Ecological characteristics, Propagation, cultivation and Management of Garden Flower seedlings
In recent years, with the advance of greening projects in China, the seedling industry has also ushered in a new "spring", and the enthusiasm of seedling people is also rising gradually, but in order to improve the quality of landscaping construction, the reproduction, cultivation and management of flower seedlings have also become the key technology that modern seedling people should master. Below, the editor of Huinong Network will talk to you about the techniques of breeding, cultivation and management of garden flower seedlings.
1. Ecological characteristics
1.1 herbaceous flowers
Herbaceous flowers can be divided into annual flowers, biennial flowers, indoor foliage plants, bulb flowers, perennial root flowers and pulpy flowers and so on. Different flower species have different ecological habits and growth conditions, and have different requirements for growth environment. Take annual flowers as an example, their growth cycle is slightly shorter and their cold tolerance is poor, so they are suitable for sowing in spring and blooming in summer and autumn. the common annual flowers are cockscomb, marigold and peacock flowers; compared with annual flowers, biennial flowers have stronger cold tolerance and are suitable for sowing in autumn and winter, and blooming in spring. Common biennial flowers include pansy, violets and carnation. Perennial flowers are perennial flowers, which have strong growth cycle and long survival time. The common perennial flowers are peony, asparagus and African chrysanthemum.
1.2 Woody flowers
Woody flowers are mainly divided into shrubs, vines and trees. Shrub flowers usually grow in clusters, without obvious trunk and side branches, such as rose, primrose and peony, etc. Liana flowers are mostly deciduous vines, which need to be attached to other objects before they can grow; Arbor flowers are mainly divided into evergreen trees and deciduous trees, with tall and straight plants, distinct trunks and luxuriant side branches, such as cherry blossoms, crape myrtle and plum blossoms.
2. Reproduction and cultivation techniques.
2.1 sowing techniques
In the construction of landscaping, sowing is the most commonly used breeding technology, which is easy to operate and has a wide range of applications. it is a commonly used method in the reproduction and cultivation of garden flower seedlings, but the defect of this method is also obvious. that is, the survival rate of flower seeds is not high. Therefore, generally speaking, flower seeds can be treated before sowing, so as to improve the seed germination rate by shortening the germination time of flower seeds, so as to improve the seed survival rate. At the same time, some measures should be taken to control the growth rhythm of flowers, the flowers with the same growth rhythm are more convenient to manage, and make the garden flowers more beautiful, and improve the quality of landscaping construction to a certain extent.
2.2 Cuttage technique
Different from sowing technology, cutting technology uses the vegetative organs of flowers as materials for propagation, and its process is to bury the vegetative organs of flowers growing to a certain stage in the soil to make them grow into new plants. The plants cultivated by this technique can adapt to the environment and climate well, so the survival rate is also quite high. However, different varieties of flowers can be used for reproduction of different vegetative organs, which requires the relevant landscaping staff to have a full understanding and understanding of the vegetative organs of different kinds of flowers, so as to make better use of cutting technology. carry out the reproduction and cultivation of garden flower seedlings. For example, the vegetative organs that crape myrtle and pomegranate can be used for reproduction are mature branches, rose, sweet-scented osmanthus and rhododendron should use mature branches and leaves as cuttings, while American Lingxiao and cloves should use root segments for cutting.
2.3 grafting technique
Through the grafting technique, the vegetative organs of one kind of flower are grafted onto another plant, and two different flowers can be combined into a new plant. This technology requires a high technical level of garden staff, as well as the grafting time of flowers and the selection of rootstocks. Therefore, garden staff must fully understand the growth habits of flowers and master grafting techniques skillfully. In order to ensure the survival rate of grafted plants, attention should be paid to controlling light intensity, temperature and humidity during and after grafting. Generally speaking, there are many commonly used grafting methods, such as relying on grafting, cutting, splitting, lip bud grafting, square bud grafting and tender branch grafting and so on.
3. Key points of cultivation and management.
3.1 planting
In the cultivation of garden flower seedlings, the selection of suitable soil is the focus of the work. Usually, landscaping workers use rotten leaf soil, garden soil, leaf fiber and perlite and other materials to prepare cultivated soil. In the process of cultivation, the root damage of seedlings should be avoided or reduced, and the pot should not be too deep, so as to facilitate the seedlings to absorb water and fertilizer. After the plants are mature, the pots should be changed regularly to meet the nutritional needs of flower growth and ensure the healthy growth of flowers.
3.2 Water and fertilizer management
Reasonable water and fertilizer management is the key to promote the growth of flowers and plays a very important role in the healthy growth of flowers. Garden workers should reasonably arrange the watering time and cycle of flowers, and the water used for watering should be mild soft water; while fertilization requires staff to decide according to the law of fertilizer demand and actual growth of flowers, and flexibly adjust the times of fertilization with the change of season and climate to make flowers fully absorb nutrients.
3.3 Pest prevention
We should have a comprehensive understanding of the period of flower pests, regularly monitor the growth of flowers in the period of high incidence of insect pests, and formulate corresponding control strategies. For different kinds of flowers, appropriate control agents must be selected to prevent flowers from being affected by insect pests in the process of growth.
The above are the garden flower seedling breeding and cultivation management techniques arranged by Huinong Network Xiaobian. I hope it will be helpful to you.
A complete collection of hydroponic culture methods for all kinds of flowers
Hydroponic culture methods of all kinds of flowers

2. The management is extensive and the growth rate is fast. The plants should be renewed frequently. The top branches of the overgrown plants should be cut off and cultivated separately, and there will be new roots in about 10 days. The axillary buds on the old stem will also sprout quickly.
3. Hydroponic fruit taro should choose white butterfly fruit taro with bright leaves, small plants with pink butterfly fruit taro and silver leaf fruit taro for vertical cultivation, because of its bright leaf color and butterfly shape, it is of ornamental value.
Ji pineapple
After flowering, the root buds can be planted in water, and the root buds should not be too small when they are separated. They can be broken off by hand, flatten the base and peel off several leaves near the base, put them in a container and make them touch the water surface. In shade and 20 ℃ environment, they can take root in 2-3 weeks. Potted plants can also be hydroponically cultured after root washing, but it takes more than one month and less rooting. The pH of the nutrient solution is between pH4-5. Ji pineapple is small in size and bright in color. It is a good product for desk furnishings.
Tulip
Hydroponic tulips should be selected according to the needs of flowering period, so as to ensure the freshness and beauty of tulips. The second is to control the temperature. From seed germination to flowering, it can be divided into three management periods, namely, germination stage, vegetative growth stage and flowering stage.
1. Germination period management: fill the flowerpot containing the seed ball with water (ordinary domestic water is OK), so that the root of the seed ball is immersed in water. Put the flowerpot in the indoor light place (preferably on the windowsill), keep the room temperature at 13t, and the temperature does not change too much. 4 the roots and buds will grow in 7 days, thus entering the vegetative growth period, changing the water every three days and once a week after budding. The relationship between the number of days after planting and the number of germination is as follows:
Days after bulb cultivation 1 2 3 4 5 6 7
The number of germination is 0 000 15 28 39 48
2, vegetative growth period management: during this period, with the increase of the growth amount and growth rate of roots, stems and leaves, a large amount of water is needed. To maintain the amount of water in the basin, the root-straight soak in water, the growth temperature is controlled at 15 ℃-18 ℃, the temperature can not be too high, otherwise it will grow too long, the stem will be thin and long, affecting the appearance. As the plant has phototaxis, it is necessary to often turn the direction of the flowerpot so that the stem can grow upright without tilting. After 3 weeks of growth and 4 leaves, an oval flower camp will appear at the tip of the stem, thus entering the flowering period.
3, flowering management: after budding, the temperature can also be controlled at I5 ℃-18 ℃, 5-7 days, the buds open gradually, the flowers show a bright color, after the flowers open, the flowerpot can be moved to a cool indoor place, which can prolong the flowering period, and the general flowers can be kept open for 2 min for 3 weeks.
Leave the ball Lanlugen
The orchid is a good material for flower arrangement because of its fragrance, beautiful color and long flowering period.
The orchid has always been cultivated with soil. Through the experiment of exposed root hydroponics, it has the following characteristics: ① saving labor, ② sanitation, less ③ diseases and insect pests, simple ④ management, long flowering period of ⑤, and ⑥ appreciating leaves and flowers with considerable roots.
The method of water culture of dew root is:
(-) Seedling treatment: dig up the soil-grown orchids, wash them with clean water, cut off withered leaves and leaves of diseases and insect pests, and soak them in diluted flower nutrient solution for half a day.
(2) on the basin: take a glass bottle or vase (without bottom hole), put several beautiful river stones at the bottom of the bottle, move the treated orchid seedlings onto the river stone of the vase, unfold the roots, add clear water, add flower nutrient solution, and place them indoors or in a cool place.
(3) Management: first, spray leaves with clear water once a day, spray leaves with flower nutrient solution every three to four days after one or two days: change water on one side every 15 days, and add nutrient solution after changing water; third, one month after the pot, the head of orchid is injected with flower nutrient solution, half a milliliter at a time, and then once a month to promote growth, flowering and prolong flowering.
(4) it can blossom in about two to three months after potting. Flowers withered after pruning, change water, add nutrient injection, can blossom again.
Pictures are searching on the Internet. Pictures are hard to find and depressing.
Hydroponic culture method of primrose
First, water insertion time: water insertion can be carried out all the year round, winter water insertion containers can be placed indoors to the sun, summer should pay attention to shade to prevent the hot sun. The water temperature should be kept between 15 ℃ and 20 ℃ during water insertion, so that the cuttings can take root quickly and have a high survival rate.
Second, water cuttings: cuttings select branches with strong growth and full bud eyes in that year, and the cuttings are generally 8 cm to 12 cm in length, leaving 2 to 4 nodes. Cut about 2 mm below the lowest section and bind every 10. If there are too many leaves in the upper half of the cuttings, they can be removed properly to facilitate rooting.
Third, water containers: containers are large-caliber pots or shallow-bottomed wide-mouth bottles, which must be washed before use.
Fourth, the method of water insertion: the container contains clean Rain Water, river water or tap water, up to 8 cm to 10 cm deep, then arrange the bound cuttings into the water, with a depth of 4 cm to 6 cm, and then put the container in an outdoor ventilated and semi-shaded place. the water quality must be kept fresh and clean, and the water can be changed every 3 to 5 days. Generally, tumor-like healing tissue can be produced about 20 days after insertion, and fibrous roots can grow in 35 to 40 days.
Fifth, timely planting: when the whisker root grows to 3 cm to 5 cm, it must be planted in time, pay attention to the operation carefully, do not damage the root system, generally after planting shade treatment for about 10 days, you can carry out normal management.
Gentleman orchid
Container selection
In order to carry out hydroponic culture of Cymbidium, we should first choose a good container. Generally speaking, it is better to use a transparent glass container. If you raise a seedling, you only need a glass can. If you want to plant a lot of water, you can use fine wire to compile a metal mesh with a diameter of one centimeter, and make a glass hydroponic box slightly smaller than the metal mesh, or you can use a goldfish tank instead. Then the metal net was covered on the hydroponic box, and the seedlings of Cymbidium were inserted into the nutrient solution through the mesh, and the depth of the flower root in the culture medium did not exceed the limit of the false bulb of the root.
Preparation of nutrient solution
Nutrient solution is divided into inorganic and organic. The inorganic nutrient solution can be prepared according to the following proportion: calcium 1. 5 grams, ferrous sulfate 0. 01 grams, urea grams, potassium dihydrogen phosphate 1 grams, magnesium sulfate 0.5 grams, the above five inorganic salts together, dissolved in 1000 grams of water can be used. The organic culture solution was prepared as follows: fried flax seed flour 100g, bone powder (made of salt-free fresh bone) 100g, bean cake powder 150g, cooked sesame powder 50g, and then dissolved in 1000 grams of water. Compared with the above two kinds of nutrient solution, the composition of organic fertilizer is rich, but the nutrient content is not high, and the composition of inorganic fertilizer is relatively simple, but the fertilizer effect is high and the effect is fast. In order to learn from each other's strong points to offset their weaknesses, the two can be used together. If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.
Use water
In hydroponic cultivation, tap water cannot be used directly, but "trapped" water must be used. The so-called "trapped" water means putting tap water in a container and drying it in the sun for five days to precipitate chlorides such as bleach that are harmful to the roots of the orchid. The "trapped" water, from the outside, the sediment changes from strips to lumps, and the color of the water is green. After "trapping" good water, the position of the submerged root must not submerge the false bulb. If the water level is too shallow, the magnolia can not get sufficient water supply, and if the water level is too deep (flooding the false bulb), it will cause root fester. In the process of breeding, we should pay more attention to observe the changes of water quality, and find that some roots turn yellow or black, indicating that the water is both anoxic and less fertile, and the water must be changed immediately.
Air, sunshine, temperature
Whether we can deal with the ventilation of hydroponic orchid root is the key to the success or failure of hydroponic culture. After a period of culture, there is a layer of moss on the root. When the moss is too thick, it will seriously affect the respiration of the root and corrode the culture medium. At this time, you need to gently brush off the moss layer with a soft and clean brush (you don't have to brush it clean, because a small amount of moss at the root has little effect). In addition, always check whether there is enough oxygen in the water. The method of inspection is to put two or three small fish into the water culture box. If the small fish swim freely in the water, it means that there is no lack of oxygen in the water. If the small fish always float to the surface, their mouths and gills are exposed to the surface to breathe, which means there is no oxygen in the water. It is found that after anoxia in the water, oxygen must be replenished. There are two methods: one is to change the water, and the other is to supply oxygen to the water with a small oxygen pump. In the treatment of sunlight, Magnolia is a semi-yin-yang plant, we should pay attention to the light, especially in summer, to avoid the strong direct sunlight, so that it can receive scattered light. In addition, according to the light-oriented characteristics of Cymbidium leaves, we should pay attention to make the leaves receive light evenly, otherwise the leaf length will be different, the growth direction will be scattered back and forth, and the illumination angle should be adjusted every two or three days. In terms of temperature treatment, the ambient temperature of adult Cymbidium should be 11 ℃-25 ℃, and the seedlings can be slightly higher, 20 ℃-35 ℃. The temperature difference between day and night should be mastered in orchid cultivation in water, which should be kept at about 20 ℃ during the day and not less than 15 ℃ at night in winter.
Rose
After the rose flower fades, cut off the remnant flowers, let the flower branches grow for several days, wait for the first axillary bud on the flower branch to grow stout and accumulate nutrients, then cut off the cuttings of 3 nodes, remove the petiole of the bottom layer, and cut the bottom bud surface into a bevel with a sharp blade. Immediately insert it into a prepared bottle filled with clean water, and the insert can be inserted into the water. In order to reduce the water evaporation of leaves, some leaves can be cut off. In the case of avoiding light, the incision is easy to grow new roots, so brown bottles should be used. If there is no brown, you can wrap the bottle with a black plastic film. Put the bottle on the south-facing windowsill and do not bask in the sun directly.
When the temperature is high, the water can be changed once a week. When the temperature is 15-25 ℃, it only takes about 20 days to grow roots, and when the young roots grow to 1-2 cm long, they can be transplanted in a pot. Because the young root grows in water, in order to make it adapt to the environment, it is watered once a day at the beginning of transplanting, and then decreases gradually. After a week of shading, you can see the sun sooner or later, and you can survive.
The water insertion method has the advantages of simple method, high survival rate, no time limit, and can be cut and inserted after the flower fades.
Cuckoo
Soilless cultivation is characterized by replacing soil with man-made substrates. The soilless cultivation of rhododendron with solid substrate in Hunan Forestry Institute has achieved very satisfactory results. The variety is summer cuckoo, the crown structure of soilless cultivation is compact, the number of flowering is large, the flower diameter is large, and there are few diseases and insect pests. It not only improves the quality of flowers, but also greatly reduces the heavy physical work, so it is a cultivation method worth popularizing.
1. Preparation of matrix
The root system of rhododendron is very slender, which requires loose matrix to facilitate air permeability and drainage. 1 part of vermiculite, 1 part of pearl sand, 1 part of river sand and 1 part of cinder were mixed in proportion. After mixing the substrate, sterilize it with 0.1% carbendazim solution, mix it evenly into the substrate and cover the plastic film for 1 day. Then rinse with clean water for many times, dry, mix well with 0.4% agricultural compound fertilizer solution, then cover it with plastic film for a month, and then use it in the basin.
two。 Preparation of nutrient solution
Azaleas have strict requirements for fertilizers. During the growing period, thin fertilizer is applied diligently. According to the experiment, good results can be obtained by spraying low concentration foliar fertilizer with agricultural compound fertilizer as the main fertilizer, supplemented with trace elements, PH value controlled at about 5.
The preparation of a large number of elements: 1 liter of water plus 2 grams of agricultural compound fertilizer and 0.5 grams of magnesium sulfate is the standard solution.
The preparation of trace elements: 1 liter of water plus 20 grams of disodium ethylenediamine tetraacetate, 15 grams of ferrous sulfate, 4 grams of manganese sulfate, 6 grams of boric acid, 0.2 grams of zinc sulfate, 0.1 grams of copper sulfate and 0.2 grams of ammonium molybdate as mother liquor. When in use, 1 liter of standard liquid and 1 ml of trace element mother liquid are all elements. The preparation of foliar fertilizer: 1g urea, 1g potassium dihydrogen phosphate, 0.02g boric acid and 0.1g V.B1 in 1 liter of water.
3. Water and fertilizer management
Because the substrate has good drainage and air permeability, but the water retention is poor, so the amount of water is generally more than that of soil culture, in order to keep the substrate moist; at this time, pregnant buds and leaf buds germinate, requiring a large amount of fertilizer, and the full amount of nutrient solution is poured once in about 10 days. From March until the buds burst, foliar fertilizer is sprayed every 15 days or so. After flowering, there is a large amount of water, in addition to watering every day, foliar watering should be carried out in the evening. At this time, the amount of fertilizer is also large, so it can be changed to irrigate the nutrient solution once a week and spray foliar fertilizer once a week to promote the sturdiness of new branches and facilitate flower bud differentiation. After the ambush, pay attention to keep the substrate moist, and sprinkle water to the leaf surface, the amount of fertilizer can be reduced to about 20 days to pour nutrient solution. After the autumn is cool, you can gradually increase the amount of fertilizer, apply a full amount of nutrient solution once in half a month, and spray 1 Mel foliar fertilizer twice to promote the robust growth of flower buds. After the beginning of winter, the physiological activity of rhododendron is weak, so it is not suitable to apply fertilizer, but can be watered properly according to the dry and wet degree of the substrate. In the process of cultivation, there were almost no diseases and insect pests.
Hyacinth hydroponics
Hyacinth is not only a lily plant, but also a bulbous flower. Hyacinth has plump inflorescences, various colors and white roots.
Key points of hydroponics:
(1) choose and buy a container that can hold the bulb, preferably a gourd-shaped container with a small top and a large bottom, with a better transparent glass texture. Some household utensils such as goblets and bottles can be selected, as well as large-mouthed containers.
(2) the water temperature should not be high, and it is better to be below 15 ℃.
(3) after putting the bulb on the bottleneck, the water level can be lowered to just touch the water surface of the root, so that the root can fully absorb oxygen and promote the growth of the root. When the root develops, the black cloth covers the culture container and allows the bulb to develop further.
(4) move the container to a sunny place in winter to make the flowers big and strong.
(5) several hyacinths can also be planted in the fish tank, and the matrix is made of sand and shady ferns to form a wild and interesting small scene, which is also very chic.
African chrysanthemum
Compositae perennial root herbs, large flower diameter, rich flowers and colors, often blooming all the year round. Like warm, sunny and well-ventilated environment, is a semi-cold-resistant flowers, like fertile and loose. African chrysanthemum is a good variety of cut flowers, which can be cultivated in water for a long time, highly ornamental, and good at absorbing formaldehyde.
Water farming of these plants generally does not require special management. Containers with a certain volume for root expansion can be used, while glass containers with open mouth are more beneficial to maintaining water quality and root growth. When planting, you should avoid immersing the leaves in water so as not to cause decay; under suitable light conditions, you can quickly take root; when you find less water, add some water to prevent the root system from drying; when the water becomes dirty, take out the plant, clean the container, and rewater it. General water plants, three days to change the water, apply a nutrient solution, the proportion of the nutrient solution and how much depends on the size of the plant.
Asparagus asparagus
Alias: Yunpian bamboo, plantain grass
Families and genera: Liliaceae, Tianmen winter genus
Morphological features: asparagus plant shape is elegant, leafy branches are slender and beautiful, shaped like clouds, bamboo is not bamboo, posture is elegant, water root is fleshy and white, coupled with a transparent container of scenery, it is not only dignified and beautiful, but also noble and elegant, so it is a good product in hydroponics.
Growth habits: like warm, humid and semi-humid environment, suitable temperature 15-25 degrees Celsius, motivation minimum temperature not less than 5 degrees Celsius, like scattered light, avoid direct strong light, avoid dry air.
Key points of hydroponics:
1) sampling: select the soil culture plants with good shape and vigorous growth, wash the soil and cut off the rotten roots and plant them in the hydroponic container, and add water to the root system of 1/3-1/2.
2) maintenance: start to change the water every 2-3 days, remove the rotten roots in time, and after two weeks, the roots basically adapt to the environment and have already grown water roots. after that, the fresh water can be changed every 5-6 days. when the plants show strong growth potential, the nutrient solution should be cultured with nutrient solution, which should be shallow rather than deep, and should be replenished every 10 days or so in summer. When the sediment of the nutrition industry is increased to renew the nutrient solution, it is generally updated once a month. Avoid bright light in summer, and the motivation should be placed in a warm place with strong light.
Keep the room temperature above 5 degrees Celsius, spray water to the leaves when the air is dry, maintain high air humidity and clean branches and leaves.
Ivy (Hedera hellx)
Alias: Ivy
Families and genera: Araliaceae. Ivy
Because of its branches and dense leaves, it is not only the most ideal indoor and outdoor wall vertical greening material, but also an excellent ground cover plant, which is suitable for climbing buildings, walls, steep slopes, rock walls and shady ground, etc., the demand for pot planting is increasing day by day.
(1) morphological characteristics and varieties
Evergreen climbing vines, branches thin and soft, with aerial roots. The vine grows in a spiral shape and can climb on other objects. Leaves alternate, leathery, dark green, with long stalks, leaves on vegetative branches triangular-ovate, entire or 3-lobed, leaves on flower branches ovate to rhombic. Racemes, florets globose, yellowish. Drupe globose, black.
Chinese ivy (H.nepalensis var.sinensis), Japanese ivy, colored leaf ivy (CV.discolor), golden ivy, silver edge ivy (CV.siluer quetn) are commonly cultivated in the same genus.
(2) Ecological habits
Ivy is a typical negative vine, which can also grow in full light, grow well in warm and humid climates, and is not hardy. Lax requirements on the soil, like moist, loose, fertile soil, not resistant to salt and alkali.
(3) methods of reproduction
The nodes of ivy can take root naturally in the moist air, and will be naturally buried in the soil after touching the ground, so cuttings are often used for propagation, vegetative branches are used as cuttings, sun shading is needed in time after planting, the air humidity should be high, and the bed soil should not be too wet, and it will take root in about 20 days. (4) cultivation techniques
The cultivation and management of ivy is simple and extensive, but it needs to be planted in a place with moist soil and good air circulation. Transplantation can be carried out in early autumn or late spring and need to be pruned after planting to promote branching. Many places in the south are planted in the shade of the garden, making it naturally prostrate on the ground or on the rockery. There are many potted plants in the north, potted plants can bind all kinds of supports, traction and plastic surgery, maintain under the shade in summer, less watering, otherwise it is easy to have stem rot, if this disease occurs, the diseased plant should be separated from health, and carbendazim and methyl thiophanate should be sprayed alternately, put into the greenhouse in winter, indoor to maintain the humidity of the air, not too dry, but the pot soil should not be too wet. Hydroponic ivy can be used as a whole plant or cuttage, preferably in spring and autumn. After the roots grow in the cutting bed, the roots can be planted in the basket for root-promoting mutagenesis. Once the cultivated ivy is excellent in maintenance, clean and hygienic, it is a good product to watch at home, and the cultivated general nutrient solution on the market can also use foliage plant nutrient solution. The concentration of nutrient solution is generally 1pm 4 of the original formula.
(4) other functions
Ivy is not only a good greening plant, the whole grass can also be used as medicine, it has the effect of dispelling wind, promoting blood circulation and detumescence, and mainly treats rheumatic joint pain, low back pain and injury. Smash the juice or add water to fry and wash the affected area, which can treat sores, measles and eczema.
Kylin
Kirin is usually propagated by cutting. From April to early September, strong branches are cut as cuttings, and white milk will flow out from the wounds of newly cut stems, which can be dipped in plant ash or charcoal powder to prevent the outflow of milk. Then leave it in a dry and cool place for 3 to 4 days. After the cut is dried and shrunk, Qilin palm has no close relationship with aquatic plants, and the principle of pollution-free cultivation must be strictly followed when hydroponics. And regular replacement of new nutrient solution to increase dissolved oxygen. The temperature should not be too low in winter, or the leaves will fall. The concentration of nutrient solution must not be too high, nor should it be overshadowed, otherwise it will cause atavism, and the columnar fleshy stem of the original unicorn palm will grow, which will affect the ornamental effect; in serious cases, it will lead to rotten root death. The white floating juice of Euphorbiaceae is poisonous. In particular, do not enter the eye, be careful not to let the child misuse the entrance, the eye.
Brazilian wood
Brazilian wood has a strong adaptability to light. In the north, it can be continuously placed and watched for more than a month in the dark room, and can be placed for long-term viewing in the bright room. Like high temperature, high humidity and well-ventilated environment, prefer light and shade, but afraid of hot sun, avoid dryness, drought, loose and well-drained sandy soil. The suitable temperature for growth is from 20 ℃ to 28 ℃, the leaves should be protected from withering and drying under 13 ℃ in winter, and the overwintering temperature is 5 ℃.
Brazilian wood is often propagated by cuttings. The best season is from April to June in the north. Large columnar Brazilian wood, the perennial stem itself contains nutrients and water, and the hidden buds on the stem have a strong ability of regeneration, because of the need of decoration, it can be sawed into stem segments of different length for planting, but the end of the stem segment is sealed with paraffin to prevent water loss or infection, which is particularly important in the dry season in the north. Or choose mature and robust stem (unlignified), cut off the top of the stem with leaves, cut the upper leaves in half, peel off the lower leaves, expose stem nodes, about 10 cm to 20 cm per segment, cuttings in coarse sand, fine sawdust or humus soil 3 cm to 4 cm, insert the bed in a semi-shady environment, maintain high humidity, accept 50% to 60% sunshine, temperature 25 ℃ to 30 ℃, about 20 to 30 days can take root and sprout, on the basin. When the stem segment is used as cuttings, the rooting is slow, and sometimes it takes 2 to 3 months to sprout and root. It can also be inserted with water and propagated under high pressure, but it should be carried out under the condition of more than 25 ℃. Water insertion propagation, that is, the stem cuttings 1x3 immersed in water, 3 to 5 days a change of water, and add a small amount of carbendazim aqueous solution antiseptic disinfection, can promote fast rooting and bud growth.
Tequila
Common varieties of tequila are: Phnom Penh tequila, Jinxin tequila, silver tequila, green tequila and narrow tequila and so on.
Strong sex, like the sun, not resistant to shade. It is slightly cold-tolerant and can be cultivated in the open field at the temperature above 5C. The leaves of adult tequila are only slightly frostdamaged at the low temperature of-5C, the aboveground parts of-13C are frozen and rot, the underground stem does not die, and the leaves can sprout and grow normally in the next year. Strong resistance to drought. Like well-drained, fertile and moist sandy soil. The origin usually takes several decades before flowering, but the mother plant dies after flowering and does not blossom in Nanjing. Cross-pollination can only bear fruit.
Tequila can be hydroponically cultured all year round in a heated environment. When hydroponic, all its roots need to be removed, disinfected with disinfectant, and then soaked in rooting solution for a certain period of time. During hydroponic culture, attention should be paid to cabbage insects eating their leaves and hearts, thus losing commercial value and ornamental value. If insects are found to be caught manually, insecticides can also be used to kill them.
Hydroponics should always get a sunny place, do not put it in a dark place for a long time, so that the leaves are easy to whiten and become thinner, thus losing ornamental value, pay attention to heat preservation in winter, put them near the window in the sunny place during the day, and put glass bottles in plastic or cardboard boxes if there is no heating at night. If the leaves turn yellow or droop downward, it may be frostbite. At this time, we need to give it some measures to keep warm. Then put it away from the door and window, and remember not to put it near the north. When changing water in winter, you can change water with warm water of 12 to 18 degrees. Tequila is resistant and can pass the winter safely as long as you pay attention to management.
Make a fortune tree
The rich tree is a perennial evergreen shrub, native to the Malay Peninsula and the Nanyang Islands. In recent years, through cultivation and breeding, it has widely entered the urban and rural families of our country. As a family cultivation, we should pay attention to the following four points according to their living habits of high temperature, humidity, frost and dryness:
One is to pay attention to the sunshine. The rich tree likes high temperature, humidity and sunlight, so it can't be shaded for a long time. Therefore, it should be placed in a sunny place indoors during maintenance and management. When placed, the leaves must be facing the sun. Otherwise, because the leaves tend to light, the whole branches and leaves will be distorted. In addition, spray water on the leaves every 3 to 5 days, which is not only conducive to photosynthesis, but also make the branches and leaves more beautiful.
Hydroponic Culture method of Catharanthus roseus
Apocynaceae Catharanthus roseus, also known as five-petal plum.
Biological characteristics: Catharanthus roseus is native to eastern Africa. Prefer a warm, slightly dry and sunny environment. The suitable temperature for growth is 18: 24 ℃ from March to July, 13: 18 ℃ from September to March of the following year, and the winter temperature is not lower than 10 ℃.
Catharanthus roseus avoid dampness and fear of waterlogging, basin soil watering should not be too much, too wet affects growth and development. In particular, indoor winter plants should be strictly controlled watering, it is better to dry, otherwise it is easy to freeze. Open field cultivation, midsummer showers, pay attention to timely drainage, so as not to cause the whole area to die by waterlogging.
Catharanthus roseus is a light-loving plant, there must be sufficient sunshine during the growing period, the leaves are green and shiny, and the flowers are bright. If you grow in the shade for a long time, the leaves will turn yellow and fall.
Suitable for fertile and well-drained loam, resistant to barren soil, but do not be alkaline. Clayey soil with hardening and poor ventilation results in poor growth of plants, yellowing leaves and no flowering.
Propagation methods: commonly used sowing, cutting and propagation.
Cultivation and management: seedlings with 3 pairs of true leaves were transplanted to 10 cm pots with 3 plants in each pot. When the seedling is 7cm high, the heart is removed once, and then twice again, so as to promote more germination and branching and more flowering. Fertilize once every semimonthly during the growing period, or use the special fertilizer of "Huiyou" potted flowers with 15mur15Mu30. Potted plants or flower beds were planted in the basin, blooming from late May to early November for more than 5 months. Remove the residual flowers at any time during the flowering period so as not to affect the plant growth and ornamental value. The harvest period of Catharanthus roseus is from August to October, and it should be picked along with ripening so as not to lose the seeds.
Pest control: often harmed by leaf rot, rust and root wart nematodes. Leaf rot was sprayed with 65% Dysen zinc wettable powder 500 times. The rust was sprayed with 2000 times the solution of 50% verapamil wettable powder. Control of root wart nematode with 50-fold solution of 80% dibromochloropropane EC
The method of hydroponics in Caiyun Pavilion
Euphorbiaceae Euphorbiaceae, also known as the triangular overlord whip. Originally from South Africa.
Features
Caiyun Pavilion is a perennial succulent plant. The stem is erect, 3-angled and 4-angled, dark green, with gray-green irregular beautiful markings in the center of the stem. The edge has a dentate process, and there are Obovate leaves at the protuberance. There are many branches, all vertical upward, forming a unique plant shape. The whole plant contains repeated milk. Caiyun Pavilion, with its peculiar shape and exotic customs, is a good product for several tables of green decoration.
Habit
Caiyun Pavilion likes to be half overcast, but it requires sufficient scattered light. Can withstand a low temperature of 5 degrees. Caiyun cabinet likes to dry and avoid wetting for a long time, but it is very suitable for hydroponic conditions.
Reproduction
Caiyun Pavilion usually uses cutting to propagate. From May to September, about 10 cm of the branches of the mother plant were taken as cuttings for cutting. The cuttings cut should not be cut immediately, for immediate cutting will cause the rot of the cut and lead to the failure of cutting. Caiyun Pavilion cut will flow out of milk, cut should be dipped in plant ash or toner, and dry in the shade for several days, after the incision is fully dry before cutting, it is very easy to take root.
Key points of water training
1: if there is a shell bug, in addition to moving it to a ventilated and transparent place, you can use a toothbrush to remove the shell bug and spray 250 liquid detergent to kill it.
2: the white emulsion in the stem of Caiyun cabinet is poisonous. Be especially careful not to look into the eye.
The method of obtaining hydroponic material
Cuttings and root washing. The cut branches should be dried in a cool and ventilated place for several days, and then inserted into the water after the incision is dry, otherwise it will rot and new roots can grow after a month.
Hydroponic method of cyclamen
Select cyclamen and containers to select 1-3-year-old cyclamen plants that are pest-free, vigorous and budding, and are best cultivated with soilless substrates such as perlite, vermiculite and sawdust. After changing the environment, it does not hurt the roots, does not slow the seedlings, and adapts quickly. Water containers are simple and economical, and can play the role of waste utilization in daily life, as long as they can hold water, such as fish tanks, teacups, beverage boxes, wine bottles and vases; transparent containers are the best, and roots, stems, leaves, flowers and fruits can be fully viewed. No matter what kind of container is used, its size, height and color should be consistent with cyclamen plants, so as to show the exquisitely carved, crystal and elegant charm of water-raised cyclamen.
Water culture time and methods the florescence of cyclamen is usually from October to June of the second year, so the water culture time is generally from September to April of the second year. The selected cyclamen plants are removed from the pot and washed with 20 ℃ warm water to wash the matrix adhered to by the root system. Then put it directly into a pre-prepared container, the depth of the water is flush with the rhizosphere, the deepest can not exceed 1 / 3 of the bulb to prevent the corm from rotting. Finally, put it in the right place in the room, add water and nutrient solution regularly. After the flowers failed in water for two to three months, the plants were taken out and planted in the cultivation medium for the summer.
Water quality, water temperature water cyclamen water used had better be mountain spring water or magnetized water, the water quality is clean, not turbid, not precipitated, and contains a variety of trace elements necessary for plants, there is no need to change water during the whole water culture period. Tap water contains chlorine, which is disadvantageous to the growth of flowers, and it is easy to be turbid and precipitate. It should be changed every few days and should not be used as far as possible. The water temperature should be close to the indoor temperature at that time, usually 10 ℃ to 20 ℃.
Light, indoor temperature cyclamen like sunny environment, water containers should be placed on the indoor sunny table or windowsill, not directly on the radiator. The most suitable indoor temperature is 15 ℃ to 20 ℃, the highest is not more than 25 ℃ and the lowest is not less than 10 ℃. Adding nutrient solution to raise cyclamen should also supplement nutrition regularly during flowering. Generally, 50ml 1 ∶ 100x ornamental plant nutrient solution is added to each plant every 10 days, and mountain spring water is also used to prepare nutrient solution. If you find yellow leaves, small leaves, small flowers, etc., in the case of excluding rotten roots, you can add more nutrient solution as appropriate.

The pH of the nutrient solution is between pH4-5. Ji pineapple is small in size and bright in color. It is a good product for desk furnishings.
Tulip
Hydroponic tulips should be selected according to the needs of flowering period, so as to ensure the freshness and beauty of tulips. The second is to control the temperature. From seed germination to flowering, it can be divided into three management periods, namely, germination stage, vegetative growth stage and flowering stage.
1. Germination period management: fill the flowerpot containing the seed ball with water (ordinary domestic water is OK), so that the root of the seed ball is immersed in water. Put the flowerpot in the indoor light place (preferably on the windowsill), keep the room temperature at 13t, and the temperature does not change too much. 4 the roots and buds will grow in 7 days, thus entering the vegetative growth period, changing the water every three days and once a week after budding. The relationship between the number of days after planting and the number of germination is as follows:
Days after bulb cultivation 1 2 3 4 5 6 7
The number of germination is 0 000 15 28 39 48
2, vegetative growth period management: during this period, with the increase of the growth amount and growth rate of roots, stems and leaves, a large amount of water is needed. To maintain the amount of water in the basin, the root-straight soak in water, the growth temperature is controlled at 15 ℃-18 ℃, the temperature can not be too high, otherwise it will grow too long, the stem will be thin and long, affecting the appearance. As the plant has phototaxis, it is necessary to often turn the direction of the flowerpot so that the stem can grow upright without tilting. After 3 weeks of growth and 4 leaves, an oval flower camp will appear at the tip of the stem, thus entering the flowering period.
3, flowering management: after budding, the temperature can also be controlled at I5 ℃-18 ℃, 5-7 days, the buds open gradually, the flowers show a bright color, after the flowers open, the flowerpot can be moved to a cool indoor place, which can prolong the flowering period, and the general flowers can be kept open for 2 min for 3 weeks.
Leave the ball Lanlugen
The orchid is a good material for flower arrangement because of its fragrance, beautiful color and long flowering period.
The orchid has always been cultivated with soil. Through the experiment of exposed root hydroponics, it has the following characteristics: ① saving labor, ② sanitation, less ③ diseases and insect pests, simple ④ management, long flowering period of ⑤, and ⑥ appreciating leaves and flowers with considerable roots.
The method of water culture of dew root is:
(-) Seedling treatment: dig up the soil-grown orchids, wash them with clean water, cut off withered leaves and leaves of diseases and insect pests, and soak them in diluted flower nutrient solution for half a day.
(2) on the basin: take a glass bottle or vase (without bottom hole), put several beautiful river stones at the bottom of the bottle, move the treated orchid seedlings onto the river stone of the vase, unfold the roots, add clear water, add flower nutrient solution, and place them indoors or in a cool place.
(3) Management: first, spray leaves with clear water once a day, spray leaves with flower nutrient solution every three to four days after one or two days: change water on one side every 15 days, and add nutrient solution after changing water; third, one month after the pot, the head of orchid is injected with flower nutrient solution, half a milliliter at a time, and then once a month to promote growth, flowering and prolong flowering.
(4) it can blossom in about two to three months after potting. Flowers withered after pruning, change water, add nutrient injection, can blossom again.
Pictures are searching on the Internet. Pictures are hard to find and depressing.
Hydroponic culture method of primrose
First, water insertion time: water insertion can be carried out all the year round, winter water insertion containers can be placed indoors to the sun, summer should pay attention to shade to prevent the hot sun. The water temperature should be kept between 15 ℃ and 20 ℃ during water insertion, so that the cuttings can take root quickly and have a high survival rate.
Second, water cuttings: cuttings select branches with strong growth and full bud eyes in that year, and the cuttings are generally 8 cm to 12 cm in length, leaving 2 to 4 nodes. Cut about 2 mm below the lowest section and bind every 10. If there are too many leaves in the upper half of the cuttings, they can be removed properly to facilitate rooting.
Third, water containers: containers are large-caliber pots or shallow-bottomed wide-mouth bottles, which must be washed before use.
Fourth, the method of water insertion: the container contains clean Rain Water, river water or tap water, up to 8 cm to 10 cm deep, then arrange the bound cuttings into the water, with a depth of 4 cm to 6 cm, and then put the container in an outdoor ventilated and semi-shaded place. the water quality must be kept fresh and clean, and the water can be changed every 3 to 5 days. Generally, tumor-like healing tissue can be produced about 20 days after insertion, and fibrous roots can grow in 35 to 40 days.
Fifth, timely planting: when the whisker root grows to 3 cm to 5 cm, it must be planted in time, pay attention to the operation carefully, do not damage the root system, generally after planting shade treatment for about 10 days, you can carry out normal management.
Gentleman orchid
Container selection
In order to carry out hydroponic culture of Cymbidium, we should first choose a good container. Generally speaking, it is better to use a transparent glass container. If you raise a seedling, you only need a glass can. If you want to plant a lot of water, you can use fine wire to compile a metal mesh with a diameter of one centimeter, and make a glass hydroponic box slightly smaller than the metal mesh, or you can use a goldfish tank instead. Then the metal net was covered on the hydroponic box, and the seedlings of Cymbidium were inserted into the nutrient solution through the mesh, and the depth of the flower root in the culture medium did not exceed the limit of the false bulb of the root.
Preparation of nutrient solution
Nutrient solution is divided into inorganic and organic. The inorganic nutrient solution can be prepared according to the following proportion: calcium 1. 5 grams, ferrous sulfate 0. 01 grams, urea grams, potassium dihydrogen phosphate 1 grams, magnesium sulfate 0.5 grams, the above five inorganic salts together, dissolved in 1000 grams of water can be used. The organic culture solution was prepared as follows: fried flax seed flour 100g, bone powder (made of salt-free fresh bone) 100g, bean cake powder 150g, cooked sesame powder 50g, and then dissolved in 1000 grams of water. Compared with the above two kinds of nutrient solution, the composition of organic fertilizer is rich, but the nutrient content is not high, and the composition of inorganic fertilizer is relatively simple, but the fertilizer effect is high and the effect is fast. In order to learn from each other's strong points to offset their weaknesses, the two can be used together. If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.
Use water
In hydroponic cultivation, tap water cannot be used directly, but "trapped" water must be used. The so-called "trapped" water means putting tap water in a container and drying it in the sun for five days to precipitate chlorides such as bleach that are harmful to the roots of the orchid. The "trapped" water, from the outside, the sediment changes from strips to lumps, and the color of the water is green. After "trapping" good water, the position of the submerged root must not submerge the false bulb. If the water level is too shallow, the magnolia can not get sufficient water supply, and if the water level is too deep (flooding the false bulb), it will cause root fester. In the process of breeding, we should pay more attention to observe the changes of water quality, and find that some roots turn yellow or black, indicating that the water is both anoxic and less fertile, and the water must be changed immediately.
Air, sunshine, temperature
Whether we can deal with the ventilation of hydroponic orchid root is the key to the success or failure of hydroponic culture. After a period of culture, there is a layer of moss on the root. When the moss is too thick, it will seriously affect the respiration of the root and corrode the culture medium. At this time, you need to gently brush off the moss layer with a soft and clean brush (you don't have to brush it clean, because a small amount of moss at the root has little effect). In addition, always check whether there is enough oxygen in the water. The method of inspection is to put two or three small fish into the water culture box. If the small fish swim freely in the water, it means that there is no lack of oxygen in the water. If the small fish always float to the surface, their mouths and gills are exposed to the surface to breathe, which means there is no oxygen in the water. It is found that after anoxia in the water, oxygen must be replenished. There are two methods: one is to change the water, and the other is to supply oxygen to the water with a small oxygen pump. In the treatment of sunlight, magnolia is a semi-yin-yang plant, we should pay attention to the light, especially in summer, to avoid the strong direct sunlight, so that it can receive scattered light. In addition, according to the light-oriented characteristics of Cymbidium leaves, we should pay attention to make the leaves receive light evenly, otherwise the leaf length will be different, the growth direction will be scattered back and forth, and the illumination angle should be adjusted every two or three days. In terms of temperature treatment, the ambient temperature of adult Cymbidium should be 11 ℃-25 ℃, and the seedlings can be slightly higher, 20 ℃-35 ℃. The temperature difference between day and night should be mastered in orchid cultivation in water, which should be kept at about 20 ℃ during the day and not less than 15 ℃ at night in winter.
Rose
After the rose flower fades, cut off the remnant flowers, let the flower branches grow for several days, wait for the first axillary bud on the flower branch to grow stout and accumulate nutrients, then cut off the cuttings of 3 nodes, remove the petiole of the bottom layer, and cut the bottom bud surface into a bevel with a sharp blade. Immediately insert it into a prepared bottle filled with clean water, and the insert can be inserted into the water. In order to reduce the water evaporation of leaves, some leaves can be cut off. In the case of avoiding light, the incision is easy to grow new roots, so brown bottles should be used. If there is no brown, you can wrap the bottle with a black plastic film. Put the bottle on the south-facing windowsill and do not bask in the sun directly.
When the temperature is high, the water can be changed once a week. When the temperature is 15-25 ℃, it only takes about 20 days to grow roots, and when the young roots grow to 1-2 cm long, they can be transplanted in a pot. Because the young root grows in water, in order to make it adapt to the environment, it is watered once a day at the beginning of transplanting, and then decreases gradually. After a week of shading, you can see the sun sooner or later, and you can survive.
The water insertion method has the advantages of simple method, high survival rate, no time limit, and can be cut and inserted after the flower fades.
Cuckoo
Soilless cultivation is characterized by replacing soil with man-made substrates. The soilless cultivation of rhododendron with solid substrate in Hunan Forestry Institute has achieved very satisfactory results. The variety is summer cuckoo, the crown structure of soilless cultivation is compact, the number of flowering is large, the flower diameter is large, and there are few diseases and insect pests. It not only improves the quality of flowers, but also greatly reduces the heavy physical work, so it is a cultivation method worth popularizing.
1. Preparation of matrix
The root system of rhododendron is very slender, which requires loose matrix to facilitate air permeability and drainage. 1 part of vermiculite, 1 part of pearl sand, 1 part of river sand and 1 part of cinder were mixed in proportion. After mixing the substrate, sterilize it with 0.1% carbendazim solution, mix it evenly into the substrate and cover the plastic film for 1 day. Then rinse with clean water for many times, dry, mix well with 0.4% agricultural compound fertilizer solution, then cover it with plastic film for a month, and then use it in the basin.
two。 Preparation of nutrient solution
Azaleas have strict requirements for fertilizers. During the growing period, thin fertilizer is applied diligently. According to the experiment, good results can be obtained by spraying low concentration foliar fertilizer with agricultural compound fertilizer as the main fertilizer, supplemented with trace elements, PH value controlled at about 5.
The preparation of a large number of elements: 1 liter of water plus 2 grams of agricultural compound fertilizer and 0.5 grams of magnesium sulfate is the standard solution.
The preparation of trace elements: 1 liter of water plus 20 grams of disodium ethylenediamine tetraacetate, 15 grams of ferrous sulfate, 4 grams of manganese sulfate, 6 grams of boric acid, 0.2 grams of zinc sulfate, 0.1 grams of copper sulfate and 0.2 grams of ammonium molybdate as mother liquor. When in use, 1 liter of standard liquid and 1 ml of trace element mother liquid are all elements. The preparation of foliar fertilizer: 1g urea, 1g potassium dihydrogen phosphate, 0.02g boric acid and 0.1g V.B1 in 1 liter of water.
3. Water and fertilizer management
Because the substrate has good drainage and air permeability, but the water retention is poor, so the amount of water is generally more than that of soil culture, in order to keep the substrate moist; at this time, pregnant buds and leaf buds germinate, requiring a large amount of fertilizer, and the full amount of nutrient solution is poured once in about 10 days. From March until the buds burst, foliar fertilizer is sprayed every 15 days or so. After flowering, there is a large amount of water, in addition to watering every day, foliar watering should be carried out in the evening. At this time, the amount of fertilizer is also large, so it can be changed to irrigate the nutrient solution once a week and spray foliar fertilizer once a week to promote the sturdiness of new branches and facilitate flower bud differentiation. After the ambush, pay attention to keep the substrate moist, and sprinkle water to the leaf surface, the amount of fertilizer can be reduced to about 20 days to pour nutrient solution. After the autumn is cool, you can gradually increase the amount of fertilizer, apply a full amount of nutrient solution once in half a month, and spray 1 Mel foliar fertilizer twice to promote the robust growth of flower buds. After the beginning of winter, the physiological activity of rhododendron is weak, so it is not suitable to apply fertilizer, but can be watered properly according to the dry and wet degree of the substrate. In the process of cultivation, there were almost no diseases and insect pests.
Hyacinth hydroponics
Hyacinth is not only a lily plant, but also a bulbous flower. Hyacinth has plump inflorescences, various colors and white roots.
Key points of hydroponics:
(1) choose and buy a container that can hold the bulb, preferably a gourd-shaped container with a small top and a large bottom, with a better transparent glass texture. Some household utensils such as goblets and bottles can be selected, as well as large-mouthed containers.
(2) the water temperature should not be high, and it is better to be below 15 ℃.
(3) after putting the bulb on the bottleneck, the water level can be lowered to just touch the water surface of the root, so that the root can fully absorb oxygen and promote the growth of the root. When the root develops, the black cloth covers the culture container and allows the bulb to develop further.
(4) move the container to a sunny place in winter to make the flowers big and strong.
(5) several hyacinths can also be planted in the fish tank, and the matrix is made of sand and shady ferns to form a wild and interesting small scene, which is also very chic.
African chrysanthemum
Compositae perennial root herbs, large flower diameter, rich flowers and colors, often blooming all the year round. Like warm, sunny and well-ventilated environment, is a semi-cold-resistant flowers, like fertile and loose. African chrysanthemum is a good variety of cut flowers, which can be cultivated in water for a long time, highly ornamental, and good at absorbing formaldehyde.
Water farming of these plants generally does not require special management. Containers with a certain volume for root expansion can be used, while glass containers with open mouth are more beneficial to maintaining water quality and root growth. When planting, you should avoid immersing the leaves in water so as not to cause decay; under suitable light conditions, you can quickly take root; when you find less water, add some water to prevent the root system from drying; when the water becomes dirty, take out the plant, clean the container, and rewater it. General water plants, three days to change the water, apply a nutrient solution, the proportion of the nutrient solution and how much depends on the size of the plant.
Asparagus asparagus
Alias: Yunpian bamboo, plantain grass
Families and genera: Liliaceae, Tianmen winter genus
Morphological features: asparagus plant shape is elegant, leafy branches are slender and beautiful, shaped like clouds, bamboo is not bamboo, posture is elegant, water root is fleshy and white, coupled with a transparent container of scenery, it is not only dignified and beautiful, but also noble and elegant, so it is a good product in hydroponics.
Growth habits: like warm, humid and semi-humid environment, suitable temperature 15-25 degrees Celsius, motivation minimum temperature not less than 5 degrees Celsius, like scattered light, avoid direct strong light, avoid dry air.
Key points of hydroponics:
1) sampling: select the soil culture plants with good shape and vigorous growth, wash the soil and cut off the rotten roots and plant them in the hydroponic container, and add water to the root system of 1/3-1/2.
2) maintenance: start to change the water every 2-3 days, remove the rotten roots in time, and after two weeks, the roots basically adapt to the environment and have already grown water roots. after that, the fresh water can be changed every 5-6 days. when the plants show strong growth potential, the nutrient solution should be cultured with nutrient solution, which should be shallow rather than deep, and should be replenished every 10 days or so in summer. When the sediment of the nutrition industry is increased to renew the nutrient solution, it is generally updated once a month. Avoid bright light in summer, and the motivation should be placed in a warm place with strong light.
Keep the room temperature above 5 degrees Celsius, spray water to the leaves when the air is dry, maintain high air humidity and clean branches and leaves.
Ivy (Hedera hellx)
Alias: Ivy
Families and genera: Araliaceae. Ivy
Because of its branches and dense leaves, it is not only the most ideal indoor and outdoor wall vertical greening material, but also an excellent ground cover plant, which is suitable for climbing buildings, walls, steep slopes, rock walls and shady ground, etc., the demand for pot planting is increasing day by day.
(1) morphological characteristics and varieties
Evergreen climbing vines, branches thin and soft, with aerial roots. The vine grows in a spiral shape and can climb on other objects. Leaves alternate, leathery, dark green, with long stalks, leaves on vegetative branches triangular-ovate, entire or 3-lobed, leaves on flower branches ovate to rhombic. Racemes, florets globose, yellowish. Drupe globose, black.
Chinese ivy (H.nepalensis var.sinensis), Japanese ivy, colored leaf ivy (CV.discolor), golden ivy, silver edge ivy (CV.siluer quetn) are commonly cultivated in the same genus.
(2) Ecological habits
Ivy is a typical negative vine, which can also grow in full light, grow well in warm and humid climates, and is not hardy. Lax requirements on the soil, like moist, loose, fertile soil, not resistant to salt and alkali.
(3) methods of reproduction
The nodes of ivy can take root naturally in the moist air, and will be naturally buried in the soil after touching the ground, so cuttings are often used for propagation, vegetative branches are used as cuttings, sun shading is needed in time after planting, the air humidity should be high, and the bed soil should not be too wet, and it will take root in about 20 days. (4) cultivation techniques
The cultivation and management of ivy is simple and extensive, but it needs to be planted in a place with moist soil and good air circulation. Transplantation can be carried out in early autumn or late spring and need to be pruned after planting to promote branching. Many places in the south are planted in the shade of the garden, making it naturally prostrate on the ground or on the rockery. There are many potted plants in the north, potted plants can bind all kinds of brackets, traction and plastic surgery, maintain under the shade in summer, less watering, otherwise it is easy to have stem rot, if this disease occurs, the diseased plant should be separated from health, and carbendazim and methyl thiophanate should be sprayed alternately, put into the greenhouse in winter, indoor to maintain the humidity of the air, not too dry, but the pot soil should not be too wet. Hydroponic ivy can be used as a whole plant or cuttage, preferably in spring and autumn, when the root system grows in the cutting bed, it can be planted in the basket for root mutagenesis, once the cultivated ivy is excellent maintenance, but also clean and sanitary, it is a good product to watch at home, and the general nutrient solution that can be used on the market can also be used as foliage plant nutrient solution, and the concentration of the nutrient solution is generally one of the original formula.
(4) other functions
Ivy is not only a good greening plant, the whole grass can also be used as medicine, it has the effect of dispelling wind, promoting blood circulation and detumescence, and mainly treats rheumatic joint pain, low back pain and injury. Smash the juice or add water to fry and wash the affected area, which can treat sores, measles and eczema.
Kylin
Kirin is usually propagated by cutting. From April to early September, strong branches are cut as cuttings, and white milk will flow out from the wounds of newly cut stems, which can be dipped in plant ash or charcoal powder to prevent the outflow of milk. Then leave it in a dry and cool place for 3 to 4 days. After the cut is dried and shrunk, Qilin palm has no close relationship with aquatic plants, and the principle of pollution-free cultivation must be strictly followed when hydroponics. And regular replacement of new nutrient solution to increase dissolved oxygen. The temperature should not be too low in winter, or the leaves will fall. The concentration of nutrient solution must not be too high, nor should it be overshadowed, otherwise it will cause atavism, and the columnar fleshy stem of the original unicorn palm will grow, which will affect the ornamental effect; in serious cases, it will lead to rotten root death. The white juice of Euphorbiaceae is poisonous. In particular, do not enter the eye, be careful not to let the child misuse the entrance, the eye.
Brazilian wood
Brazilian wood has a strong adaptability to light. In the north, it can be continuously placed and watched for more than a month in the dark room, and can be placed for long-term viewing in the bright room. Like high temperature, high humidity and well-ventilated environment, prefer light and shade, but afraid of hot sun, avoid dryness, drought, loose and well-drained sandy soil. The suitable temperature for growth is from 20 ℃ to 28 ℃, the leaves should be protected from withering and drying under 13 ℃ in winter, and the overwintering temperature is 5 ℃.
Brazilian wood is often propagated by cuttings. The best season is from April to June in the north. Large columnar Brazilian wood, the perennial stem itself contains nutrients and water, and the hidden buds on the stem have a strong ability of regeneration, because of the need of decoration, it can be sawed into stem segments of different length for planting, but the end of the stem segment is sealed with paraffin to prevent water loss or infection, which is particularly important in the dry season in the north. Or choose mature and robust stem (unlignified), cut off the top of the stem with leaves, cut the upper leaves in half, peel off the lower leaves, expose stem nodes, about 10 cm to 20 cm per segment, cuttings in coarse sand, fine sawdust or humus soil 3 cm to 4 cm, insert the bed in a semi-shady environment, maintain high humidity, accept 50% to 60% sunshine, temperature 25 ℃ to 30 ℃, about 20 to 30 days can take root and sprout, on the basin. When the stem segment is used as cuttings, the rooting is slow, and sometimes it takes 2 to 3 months to sprout and root. It can also be inserted with water and propagated under high pressure, but it should be carried out under the condition of more than 25 ℃. Water insertion propagation, that is, the stem cuttings 1x3 immersed in water, 3 to 5 days a change of water, and add a small amount of carbendazim aqueous solution antiseptic disinfection, can promote fast rooting and bud growth.
Tequila
Common varieties of tequila are: Phnom Penh tequila, Jinxin tequila, silver tequila, green tequila and narrow tequila and so on.
Strong sex, like the sun, not resistant to shade. It is slightly cold-tolerant and can be cultivated in the open field at the temperature above 5C. The leaves of adult tequila are only slightly frostdamaged at the low temperature of-5C, the aboveground parts of-13C are frozen and rot, the underground stem does not die, and the leaves can sprout and grow normally in the next year. Strong resistance to drought. Like well-drained, fertile and moist sandy soil. The origin usually takes several decades before flowering, but the mother plant dies after flowering and does not blossom in Nanjing. Cross-pollination can only bear fruit.
Tequila can be hydroponically cultured all year round in a heated environment. When hydroponic, all its roots need to be removed, disinfected with disinfectant, and then soaked in rooting solution for a certain period of time. During hydroponic culture, attention should be paid to cabbage insects eating their leaves and hearts, thus losing commercial value and ornamental value. If insects are found to be caught manually, insecticides can also be used to kill them.
Hydroponics should always get the place where the sun is good, and do not put it in a dark place for a long time, so that the leaves are easy to whiten and become thinner, thus losing their ornamental value, pay attention to heat preservation in winter, put them near the window in the sunny place during the day, and put glass bottles in plastic or cardboard boxes if there is no heating at night. If the leaves turn yellow or droop downward, it may be frostbite. At this time, we need to give it some measures to keep warm. Then put it away from the doors and windows, and remember not to put it near the north. When changing water in winter, you can change water with warm water of 12 to 18 degrees. Tequila is resistant and can pass the winter safely as long as you pay attention to management.
Make a fortune tree
The rich tree is a perennial evergreen shrub, native to the Malay Peninsula and the Nanyang Islands. In recent years, through cultivation and breeding, it has widely entered the urban and rural families of our country. As a family cultivation, we should pay attention to the following four points according to their living habits of high temperature, humidity, frost and dryness:
One is to pay attention to the sunshine. The rich tree likes high temperature, humidity and sunlight, so it can't be shaded for a long time. Therefore, it should be placed in a sunny place indoors during maintenance and management. When placed, the leaves must be facing the sun. Otherwise, because the leaves tend to light, the whole branches and leaves will be distorted. In addition, spray water on the leaves every 3 to 5 days, which is not only conducive to photosynthesis, but also make the branches and leaves more beautiful.
Hydroponic Culture method of Catharanthus roseus
Apocynaceae Catharanthus roseus, also known as five-petal plum.
Biological characteristics: Catharanthus roseus is native to eastern Africa. Prefer a warm, slightly dry and sunny environment. The suitable temperature for growth is 18: 24 ℃ from March to July, 13: 18 ℃ from September to March of the following year, and the winter temperature is not lower than 10 ℃.
Catharanthus roseus avoid dampness and fear of waterlogging, basin soil watering should not be too much, too wet affects growth and development. In particular, indoor winter plants should be strictly controlled watering, it is better to dry, otherwise it is easy to freeze. Open field cultivation, midsummer showers, pay attention to timely drainage, so as not to cause the whole area to die by waterlogging.
Catharanthus roseus is a light-loving plant, there must be sufficient sunshine during the growing period, the leaves are green and shiny, and the flowers are bright. If you grow in the shade for a long time, the leaves will turn yellow and fall.
Fertile and well-drained soil should be used, and barren soil should be tolerated, but alkaline soil should be avoided. Hardened, poorly aerated, clayey soil resulting in poor plant growth, yellow leaves, and no flowering
Propagation methods: commonly used sowing, cuttage and propagation.
Cultivation management: seedlings with 3 pairs of true leaves transplanted to 10 cm pots, 3 plants per pot. When the seedlings are 7~8 cm high, they are picked once and then twice to promote more germination, branching and flowering. Fertilize once every half month in the growth period, or use 15-15-30 "Huyou" special fertilizer for potted flowers. Pot or flower bed from basin planting, flowering from late May to early November, as long as more than 5 months. Remove residual flowers at any time during flowering to avoid moldy residual flowers affecting plant growth and ornamental value. 8~10 months for periwinkle seed harvest period, should be picked with maturity, so as not to lose seeds.
Pest control: often leaf rot, rust and root wart nematode damage. Leaf rot was treated by spraying 500 times solution of 65% zebrazine wettable powder. Rust was sprayed with 2000 times solution of 50% chlorhexidine WP. Control of root wart nematode by spraying 50 times solution of 80% dibromochloropropane EC
Cultivation method of Caiyun Pavilion
Euphorbia family Euphorbia, also known as the triangle king whip. Originated in South Africa.
features
Caiyunge is a perennial succulent plant. Stem erect, 3~4 ribs, dark green, stem center has grayish green irregular beautiful stripes. Edge has dentate protuberances, protuberances place unripe have obovate blade,. Branches are more vertical upward, forming a unique plant shape. The whole plant contains repeated milk. Colorful clouds pavilion shape peculiar, rich exotic flavor, is a few tables green decoration Jiapin.
habits
Caiyun Pavilion likes half shade, but requires sufficient scattered light. It can withstand low temperatures of 5 degrees. Caiyun Pavilion likes to be dry, avoid long-term humidity, but it is very suitable for hydroponic conditions.
breeding
Colourful cloud Ge uses cuttage method to carry on propagation normally. From May to September, about 10 cm branches of the mother plant are taken as cuttings for cutting. Cut cuttings should not immediately cuttage, immediately cuttage will cause the rot of the incision and lead to cuttage failure. The incision of Caiyun Pavilion will flow out milk. When cutting, it should be dipped in plant ash or carbon powder, and dried in a cool place for several days. After the incision is fully dried, it is easy to take root.
Key Points of Hydroponic Conservation
1: If there are scale insects, in addition to moving them to a ventilated place, the scale insects can be brushed with a toothbrush and sprayed with detergent 250 to kill them.
2: The white emulsion in the stems of Caiyun Pavilion is poisonous. Be especially careful not to get into the eyes.
Method for obtaining hydroponic materials
Cutting and root washing. Cut branches should be dried in a cool and ventilated place for several days, and then inserted into water after the incision is dry, otherwise it will cause rot and new roots can grow after a month.
Cyclamen hydroponics
Cyclamen and container selection 1 - 3 years old cyclamen plant without diseases and insect pests, vigorous growth, budding, with soilless culture substrate such as pearlite, vermiculite, sawdust and other substrate culture is the best, after changing the environment does not hurt roots, slow seedlings, adapt quickly. Aquatic containers are simple and economical, and can play a role in waste utilization in life, as long as they are containers that can hold water, such as fish tanks, cups, beverage boxes, wine bottles, vases; transparent containers are best, roots, stems, leaves, flowers, fruits can be fully viewed. No matter what container is used, its size, height, color, etc. should be coordinated with cyclamen plants, so as to show the exquisite, crystal elegant flavor of cyclamen cultivated in water.
Cyclamen flowering time and method is generally in October to June of the second year, so the water cultivation time is generally in September to April of the second year, the selected cyclamen plants will be removed from the pot, with 20℃ warm water to wash the root adhesion matrix, pay attention not to damage the roots. Then put it directly into the prepared container, the depth of water should be flush with the rhizosphere, and the deepest should not exceed 1/3 of the bulb, so as not to rot the bulb. Finally, put it in a suitable position indoors, add water regularly, and add nutrient solution. After two to three months of water cultivation, the flowers are destroyed, and the plants are taken out and planted in the cultivation medium for summer.
Water quality, water warm water cyclamen water is best spring water or magnetized water, clean water quality, no turbidity, no precipitation, and contains a variety of trace elements necessary for plants, the whole water culture period does not need to change water. Tap water contains chlorine, adverse to flower growth, and easy to turbidity, easy to precipitate, every few days to change the water once, should try not to use. The water temperature should be close to the indoor temperature at that time, generally 10℃ to 20℃.
; light, indoor temperature Cyclamen likes a sunny environment, water containers should be placed on the indoor sunny desktop or windowsill, not directly on the radiator. The indoor temperature should be 15℃ to 20℃, the highest should not exceed 25℃, and the lowest should not be lower than 10℃. Add nutrient solution water cyclamen in flowering period should also regularly supplement nutrition, generally every 10 days each plant to add 50 ml 1:100 times of flowering plant nutrient solution, the preparation of nutrient solution should also use mountain spring water. Such as yellow leaves, small leaves, small flowers, etc., in the case of eliminating rotten roots, you can add some nutrient solution as appropriate.
