How to roll up the leaves of the Silver Queen, control fertilizer and water / pay attention to shading / timely control of diseases and insect pests

The Silver Queen is a highly ornamental green plant, which can be seen in many parts of our country, but a plant like this with beautiful leaves can also affect its appearance if its leaves are rolled up, so what about the leaves of the Silver Queen? How do we need to solve it? Next, the editor will take you to learn about it.

First, how to roll up the leaves of the Silver Queen? find the reason.

Second, the solution to the rolling up of the leaves of the Silver Queen.

1. Temperature control, 20-24 ℃

When we breed the Silver Queen, we must do a good job in temperature control, the Silver Queen is more suitable for growth in the ambient temperature between 20-24 ℃, if the indoor temperature is more than 30 ℃, it will stop growing, when the winter temperature is lower than 5 ℃, it will also affect its growth, but also affect the shape of the leaves, causing the Silver Queen leaves to roll up.

two。 Reduce fertilization and less fertilization in autumn and winter

Spring and summer are the peak growing season of the Silver Queen, and its demand for fertilizer is very high in these two seasons, so we need to fertilize frequently so that it can thrive, but after entering the autumn and winter season, its growth will gradually slow down, so at this time we have to reduce the frequency of fertilization, if it is still as frequent as the growing period, it will affect the health of the plant. It will also change the shape and color of the leaves, causing the leaves of the Silver Queen to curl up and turn yellow.

3. Control moisture and avoid stagnant water

The Silver Queen is a kind of plant that likes water, so it is necessary to keep the soil moist in the process of growth, and the leaves also need to be sprayed frequently to avoid drying up and yellowing, but we still have to control the amount of water properly. Every time we water the soil to keep a certain degree of moisture on it, remember not to water too much, if it causes stagnant water, it is easy to let it appear soft rot, and its leaves will also curl.

4. Light control, avoid strong light

The Silver Queen plant prefers to grow in a semi-shady environment, and it itself is more shady, so when we breed it, we must not put it in a place where the sun shines directly, which will cause its leaves to shrink and lack of water. as a result, the Silver Queen leaves roll up, and we should put it in indoor semi-shade when we look like it.

5. The earlier the pest control, the easier it will be.

Diseases and insect pests are also one of the reasons that cause the leaves of the Silver Queen to roll up, and in serious cases, it will also cause the plant to wither and die, so the plant must be dealt with in time when there are diseases and insect pests, because the earlier the treatment, the easier it is, and if it takes a long time, it will be very difficult to cure it. Specific prevention and control methods in the Silver Queen's pest control article has a detailed introduction, you can understand.

Practical manual for maintenance of common indoor flowers

The Azalea early flowering variety blossoms in October, the middle flowering variety blossoms in January, and the late flowering variety blossoms in February. The flowering period is about 3 months.

Cultivation principle: plant in indoor semi-shade to avoid bright light and avoid dry and high temperature environment. The lowest temperature in winter is more than 8 ℃. Watering ensures that the basin soil is moist and permeable once a week. Attention should also be paid to increasing the air humidity. Clear water should be often sprayed around the plant. If the air humidity is above 70%, it can grow well.

The key to raising cuckoos well lies in potted soil. Rhododendron is a kind of acid soil flower, which requires that the pH value of basin soil is between 5.0and 5.5. when the pH value is more than 6, it often grows badly. After the fallen pine needles are stacked and ripe, add a small part of the pastoral soil to the basin, or go to the market to buy acid soil, try not to use tap water, use cold boiled water or regularly add a small amount of ferrous sulfate diluent (about 0.1%). With the long-term use of ferrous sulfate, the soil is easy to consolidate, so it is necessary to loosen the soil.

The basin soil is also required to be loose, to maintain good drainage, and the basin bottom hole is covered upward with tile convex surface. Change the basin every spring.

Rule of thumb: remove the bud next to the bud before flowering, otherwise the flower is not easy to bloom. Take off the flower and take off the calyx. When the flower lags behind, the plant is pruned, the compound fertilizer based on nitrogen fertilizer is applied in spring and summer, and the compound fertilizer based on phosphorus and potassium is applied in autumn and winter. It is also possible to put slow-acting fertilizer into the soil when changing pots in spring, so that there is no need to apply fertilizer for a year, but the amount of fertilizer should be controlled by experience. If you don't mind the trouble, you can also rett yourself to make organic fertilizer. Go to the small mill fragrant oil factory in the free market to ask for some sesame sauce dregs, put them together with the fish scales, and completely ferment until they are foaming and odorless, mix them with water at a ratio of 1/1000, and water them once a half month.

Flowerpots with mud pots, tile pots are better, you can also use small broken flowers or blue and white porcelain pots to do set pots, do not use large pattern flowerpots.

Diseases and insect pests: small white moths will make leaves curl and wrinkle; if the air is too dry, red spiders will harm; improper cultivation methods will cause all kinds of mildew, rhododendron root rot is the most important one, the main performance is poor plant growth, leaf wilting, withering, brown spots and rotting peeling on the roots.

Daffodils like sunny, warm and humid environmental conditions. Generally select short varieties to do small potted plants, placed on the windowsill or several cases to watch, is an excellent indoor flowers in winter.

Cultivation principle: it is better to put it indoors under light. During the growing period, the ambient temperature should be kept at 15-20 ℃ and kept in clear water.

Experience: water can touch the root plate, pour it out at night and add water during the day. See the light fully, otherwise the leaves will be thin and long and will not blossom. Carving the lock will shorten the florescence, but don't touch the flower bud.

Diseases and insect pests: very few.

Poinsettia is also called Christmas poinsettia. Sex likes a sunny and warm environment. Flowering period from November to March of the following year, but also through short-day treatment, early flowering.

Cultivation principle: put it in a place with plenty of light, and you can move to the outdoor shade place in summer. The high temperature environment is required, the growing period is 25-29 ℃, and the night is 18 ℃. After coloring the bracts, the temperature dropped to 18-20 ℃, about 15 ℃ at night. Poinsettia is more resistant to low temperatures and can occasionally withstand temperatures below 5 ℃. If less than 8 ℃, less watering, more sunshine. When entering the flowering stage, use warm water to irrigate, reduce water supply when blooming, too much watering will shed leaves. Moderate humidity is required, and warm water should be sprayed frequently in rooms with high temperatures. Add a small amount of sandy soil to the basin with acid peat soil and change the basin every year or every other year. It needs a lot of nutrients in the peak growing season and fertilizes once a week from April to September. The simple way to dwarf the plant is to prune the plant after flowering every year to keep the stem height 10cm. It would be more ideal if it could be used. You can also bend and reshape at will in summer. If you want to blossom ahead of time, you can artificially shorten the sunshine, see light for 9 hours a day, and then flower after 45 days.

Experience: it is easier to feed than to raise well (the Corolla is round and plump). When growing new leaves, 30% shade is required. If the light is too strong, the leaves will burn and spot; if the light is not enough, the lower leaves will fall off, the bracts will fade, and the plants will be thin and long, not strong. Don't touch the leaves when watering, or it won't suck.

Diseases and insect pests: the dry environment will cause the harm of whitefly, shell insects and red spiders, distorting the leaves or rotting the roots.

Phalaenopsis is known as the "queen of orchids". It blooms for as long as 2-3 months and can open twice a year. 10-20 flowers can bloom on each stem without pollen and will not cause respiratory allergy. The only drawback is that there is no fragrance. The life span of each Phalaenopsis can be up to 5-10 years.

Cultivation principle: the light is required for the flowers to be cool, and it is better to block the sun with bamboo or net curtains in summer. Watering should be dry and wet, in order to increase humidity, it is best to spray water once a day, be careful not to spray on flowers, and do not spray water at noon. Fertilization can be used in the market can buy orchid special fertilizer, according to the proportion of water irrigation.

Experience: Phalaenopsis likes a cool and ventilated environment. If the environment is muggy, it is easy to rot. When planting Phalaenopsis, it is best to use porous pots in flower pots.

Anthurium andraeanum has a long flowering period and can have palms all the year round, so it is a good indoor ornamental plant.

Cultivation principle: like the light but fear the strong sunshine at noon in summer. It is put indoors in the north window in summer and in the south window in other seasons. The most suitable growth temperature is 20-25 ℃, and the room temperature in winter is not less than 15 ℃.

Wet in the watering room, knock on the flowerpot with your hand. If the sound is empty, it's time to water. Watering should be thoroughly watered to the extent that water can flow out from the bottom of the basin. In order to increase the humidity, spray water on the leaves.

Fertilizer to buy a special flower nutrition solution, 5ml plus 200-300x water, stir evenly, like watering thoroughly, once a month on it. It is best to plant in pots with holes. Change the basin every 2-3 years, usually in the spring.

Diseases and insect pests: there are nematodes, aphids, shell insects and red spiders and other hazards. If the maintenance is not good, it will lead to root rot, leaves will also produce spots and discoloration.

The flowering period of Begonia bulb is long, and the branches are more brittle from spring to autumn. It can be used as medium and small potted plants, and its hanging varieties can also be used as hanging plants together with other green leaf plants.

Cultivation principle: adapt to the cold environment, afraid of extreme heat. Like the soil is dry, the air is moist, the basin soil is too wet will cause root rot, air dryness will make male flowers fall off. I'm afraid of flooding. It's better to put it in the east-west window. The suitable growth temperature is about 20 ℃, not more than 30 ℃. When dormant, about 10 ℃. The air humidity is about 70%.

It can be often watered during the growing season, with soft water with a mild temperature and a pH value of 4.5-5. Never spray water directly on leaves and flowers, otherwise it will cause leaf mildew. In the late growing season, the amount of watering decreased gradually. Cut off the withered stems after dormancy. Tubers can be stored in peat throughout the winter and keep slightly wet.

If you like fertilizer, you should apply fertilizer at the interval between flowering periods, using the nutrient solution used for viewing flowers, 5ml and 1000ml water, stirring evenly and watering like watering. Pay attention to the fact that fertilizer and water must not be poured on the leaves, otherwise they will rot easily and even cause the death of the plant.

Diseases and insect pests: nematodes, aphids and begonia mites. When the humidity is high, it is prone to bacterial diseases. Impregnated spots appear on the edge and back of the leaves, which slowly turn brown and finally dry up. The stem is lead-gray and seems to contain purulent secretions. These diseases spread quickly, and as soon as they appear, the diseased plants should be burned immediately.

Cymbidium can be used as a small and medium-sized potted plant, which is a good indoor plant for viewing flowers and leaves.

Cultivation principle: do not like to move often, it is best to find a more fixed position. For fear of bright light, it should be placed in the south window and ventilated. Too much light will cause the leaves to turn yellow. The suitable growth temperature is 20-25 ℃, and dormancy begins when the summer temperature is above 25 ℃.

The secret of the successful cultivation of Magnolia has something to do with watering. Watering should not be too much, especially during dormancy, only a small amount of water should be given to keep the basin soil slightly wet. When the flower stem grows to about 15cm, it needs to be watered properly, but too much water can lead to macula in the leaves or root rot. It is best to use warm water close to room temperature. The leaves are often wiped in summer, watering is controlled in winter, and there is no need for fertilization.

Strong plants do not have to change pots year after year. The pot change is usually carried out after flowering. The basin soil is a mixed substrate of rotten leaves plus fertile loam and river sand.

Diseases and insect pests: sometimes harmed by scale insects and aphids. Too wet the pot soil will cause the roots to rot.

Brazilian evergreen trees. Sex likes the environment with sufficient light, high temperature and humidity, but it has a wide range of adaptation to light, is very shady, and is suitable for indoor growth.

Cultivation principle: place about 3-4 meters away from the window, or similar light, pay attention to prevent the direct light at noon, especially from March to September. However, too shady environment will lead to leaf yellowing and discoloration. As long as the temperature and other conditions are suitable, four seasons a year can be in the growth state, but it is best to make it dormant in winter, the dormancy temperature is 13 ℃. If the temperature is too low, chloasma will appear at the tip and edge of the leaf. No less than 5 ℃ in winter. Keep away from air conditioning and heating when placing.

The amount of water should be balanced and the basin soil is harmful if it is too dry or too wet. The excess water at the bottom of the basin will cause the roots to rot, so the basin floor should use a gasket with strong drainage. You'd better use Rain Water to irrigate it in summer. Water it before 10:00 or after noon, dry and wet.

Like the environment with high humidity, and keep a constant temperature, otherwise it is easy to cause diseases and insect pests. It is best to buy in spring and avoid buying in autumn and winter. Spraying can often be used to improve air humidity.

Fertilization should be applied every two weeks during the growing period, and perennial plants had better be fertilized once a week. If you want to make it dormant in winter, stop fertilization after September.

If the pot is changed every April, the new plant will be changed once a year. When the old plant is changed every other year, it generally depends on whether the root system of the old plant has grown out of the basin floor hole and then change the basin. Pot soil with peat Tujia a small amount of sesame sauce residue, because like good drainage, should add a small amount of coarse sand to mix.

Diseases and insect pests: if the environment is not suitable, there will be red spiders, thrips, shell insects harm. In addition, excessive ventilation, drought, irregular watering and excessive fertilization can cause leaf tip scorch. General plants are relatively clean and are not easy to attract insect pests. Sometimes the leaves have scorched edges, which are mostly physiological diseases caused by drought and low temperature.

Rich bamboo evergreen small trees. Suitable for medium-sized potted plants, or raised in indoor water, put in a vase, after a period of time will root out. The lighting requirement is not strict, so it can be placed anywhere indoors for a long time. Cultivation is similar to Brazilian wood, basically free of diseases and insect pests.

Tortoise back bamboo, also known as Penglai banana, Tuanlong bamboo, wire orchid.

Cultivation principle: like light, but should avoid direct light at noon in summer. The more light, the bigger the leaves and the more cracks. The tortoise-backed bamboo is very strong and shady, and can be placed in a rather dark place for a period of time. The suitable growth temperature is 20-25 ℃ and 12 ℃ in winter. The lowest temperature is 5 ℃. The air humidity is 60-70%.

The growing season should be watered frequently to keep the basin soil moderately humid. If the temperature of the plant is lower in winter, the amount of water should also decrease. Can often use lukewarm calcium-free soft water or Rain Water spray foliar, or scrub with sponge, but should stop in winter.

After June, fertilizer is applied every two weeks. When nutrients are insufficient, the leaves grow very small. If aerial roots grow into the soil, they can absorb nutrients, so part of aerial roots can be used to increase the absorption area.

Change the basin every year. Potted soil is generally potted soil. The basin is a little larger and the drainage needs to be good. In the case of totem column cultivation, the aerial root should be wrapped around the brown column to facilitate the absorption of nutrients.

Diseases and insect pests: plants are strong and rarely infected with diseases and insect pests.

Peacock bamboo taro perennial evergreen herb. Suitable for indoor small and medium-sized potted plants, not exquisite. The suitable temperature is 20 ℃.

Cultivation principle: like the half-yin and half-yang light environment, otherwise the leaves fade and affect the ornamental. It should be placed in a brighter place to avoid direct sunlight. It is also very Yin-resistant. Overwintering requires a temperature of 13-16 ℃, and normal room temperature for the other three seasons. The most suitable temperature is 18-25 ℃.

The requirement of humidity is higher, watering in spring and summer should be timely, basin soil should be moist, avoid drying and too much water. The amount of water should be reduced appropriately in autumn and winter. It is not enough to spray water alone, it is best to use a humidifier to increase humidity if possible. For beauty's sake, the leaves should be scrubbed frequently. Spraying with cold boiled water has the best effect.

Change the basin every other year. The basin soil should use a slightly acidic matrix with good ventilation and permeability, and peat soil can be used to add a small amount of coarse sand to make basin soil. During the growing period, fertilizer and water were irrigated every two weeks. Less or no fertilizer the rest of the time.

Diseases and insect pests: during the growing period, such as poor ventilation, it is easy to be harmed by shell insects, and when it is serious, it will hinder the growth of stems and leaves, so it can be sprayed with dimethoate diluent. The ornamental value of the blade is very high, so mechanical damage must be avoided.

Cinnamon cultivation principle: like wet, ventilated environment, if the ventilation is not good, the branches will turn yellow and the leaves will fall off. Sometimes its leaf shape will droop, due to lack of water, if it is watered in time, it can return to a straight state in four or five hours. Water thoroughly at once, and spray water on the leaves frequently to increase humidity.

Zhu Jiao is a small shrub with red, pink and green leaves, which is very beautiful.

Cultivation principle: like plenty of sunlight, but also can not direct sunlight, if the light is not enough, the flowers and leaves will gradually fade. When the soil is dry, water should be watered at the right time until the bottom of the basin comes out. But also regularly spray the foliar surface, which can increase the surrounding humidity and is conducive to plant growth.

The hulk rarely blossoms and blossoms for about a month. The flowers are white strips, the wrapping pieces are very high, it is plain sailing, and it is a good gift.

Cultivation principle: shade tolerance, but if there is no sunlight, the leaves will fade. When the soil is completely dry, it needs watering. Usually insert a stick into the soil, if there is no soil on the stick, it means it is time to water. When watering, water thoroughly until the bottom of the basin runs. In order to maintain humidity, always spray water on the leaves.

Pueraria lobata is a kind of plant that uses aerial roots to climb other things to grow. Strong shade tolerance, is an excellent material to beautify the room, can be used as totem pole, wall hanging, can also be used as water bottle or hanging plants.

Cultivation principle: Golden Pueraria likes light, but can't stand strong sunlight. It can be placed in a cool place outside, in the east-west window indoors, and in the south window in winter. If the light is not good, the light yellow spots will turn grayish yellow. The suitable temperature for growth is 15-25 ℃, and the heated room is very suitable, the lowest in winter is not less than 10 ℃. The air humidity is 40-50%.

The basin soil maintains moderate humidity in summer, and the amount of watering decreases with the decrease of temperature in winter. The plant can tolerate temporary overdrying and wetness. It is best to water the plant with calcium-free soft water. Fertilizer is applied every two weeks during the growing season.

Young plants change pots every year, forming a change of pots every 2-3 years. The basin soil is a mixed matrix of coniferous soil, charcoal block and rotten horse manure. But other soils can also be used, as long as there is no calcium or only trace amounts of calcium in the soil. Pay attention to the drainage of the basin.

Diseases and insect pests: the plant is strong, but there are few diseases and insect pests.

Camellia oleifera vines. There are two kinds of ruby taro and emerald taro. Can be used for medium and large potted plants, generally made into totem poles. Because of its strong shade tolerance, it can be placed indoors for a long time.

Cultivation principle: Xilin taro is more shady, but in bright light, it grows faster and stronger. It can be put in the window indoors. The suitable growth temperature is 20-30 ℃, and the lowest temperature must not be lower than 14 ℃. The air humidity should be about 70%.

The growing season can be often watered and leaves are sprayed twice a day. Watering plants with lukewarm water in winter, it is best to use soft water or Rain Water. Because the minerals and harmful elements in tap water are bad for the root. Plants should not be moved outdoors and washed with tap water, but should be sprayed with lukewarm water. Liquid nitrogen fertilizer is applied every two weeks during the growing season.

Change the basin every spring, carefully shake off the old-fashioned roots and cut off the dead roots. The basin soil is a mixed matrix of coniferous soil, rotten horse dung and a small amount of granular peat. The drainage of the basin needs to be very good, the remaining water will make the leaves of the plant yellow, and if the amount of water is too little, the cotyledons will turn yellow.

Diseases and insect pests: Camellia oleifera is generally not easy to be infected with diseases and insect pests, but incorrect maintenance will make it attacked by shell insects.

Tiger tail orchid, also known as tiger skin orchid, tiger grass orchid, millennium orchid, brocade orchid. Perennial herbs. The main viewing object is its beautiful leaves.

Cultivation principle: like the warm temperature, need plenty of sunshine, can be placed on the south unsheltered windowsill. But can also endure shade, in the shade conditions will not die, but for too long, the leaves will become dark and old.

Tiger-tailed orchids are very easy to cultivate, but too much watering will hurt them. Its suitable temperature is 18-27 ℃, and it stops growing when it is lower than 13 ℃. The winter temperature should not be lower than 8-10 ℃ for a long time, otherwise the base of the plant will rot.

Secondly, we should pay special attention to control the amount of water, in addition to summer can be a little moist, other time can not be too humid. But the leaf surface can be kept clean by spraying water frequently. Keep a certain degree of low temperature and dry in winter. When using plastic pots or other decorative flowerpots with poor drainage, you should pay special attention to soil drainage, otherwise excess water will slowly gather, causing harm to plants. Tiger tail orchid is not strict with the hardness of water, and general water can be used.

When summer begins to grow, fertilizer can be applied 1-2 times a month, and the amount of fertilizer does not need to be much. The basin is usually changed every two years. Spring is the best season to change pots.

Diseases and insect pests: in the case of excessive humidity or high temperature fluctuations, brown spots or cork spots are easy to occur on the leaves.

Kidney ferns like a warm, moist and shady environment.

Cultivation principle: you don't need a lot of light, and you don't like direct sunlight, but if you put it in the dark, the leaves will fall off after a few weeks. The growth rate is very fast in the greenhouse and high humidity environment, although it can not grow very big, but it can still survive for a long time. Once the leaves turn yellow or fall off, you can transfer it to a drier area, keep the temperature at about 5 ℃, remove the old leaves from the plant, after 1-2 months, turn the pot to change the soil, and then put it back to the greenhouse to grow, and it will grow well in a few months.

Water requirements are more strict, should not be too wet, should not be too dry, it is best to use Rain Water watering.

Kidney ferns need a lot of nutrients to grow well, but the fertilizer should not be too thick, so it is best to water them with diluted water. Fertilizer should not be applied when growth stops or is dormant in winter. Change the basin every spring.

Diseases and insect pests: sometimes produce a large number of aphids, shell insects and other harmful plants.

Dryopteris fern is especially suitable for indoor foliage plants, can be used for large and medium-sized potted plants, can also be placed in a hanging basket, as a suspension plant.

Cultivation principle: only a small amount of sunlight is needed, so it can be put in the living room. Avoid the scorching sun. The suitable growth temperature is 15-25 ℃, 15 ℃ in winter and no less than 10 ℃. If the temperature is too low, the leaf edge will turn brown. The air humidity should be above 60%.

The growing season can be watered in large quantities and regularly, and the basin soil can be kept slightly moist in winter. In order to improve the air humidity, you can often spray water to the plant, preferably with demineralized soft water or Rain Water.

Thin fertilizer is applied every 10-14 days in the growing season. With reasonable fertilization, the plant will grow a large number of new leaves; lack of fertilizer or dry air can cause the leaf margin to appear brown. The basin is usually changed every 2-3 years, and the basin soil is a mixture of peat, rotten leaf soil and a small amount of rotten horse dung. Pay attention to the drainage of the basin.

Diseases and insect pests: there are red spiders, shell insects and other pests.

Asparagus perennial climbing herb is a good potted plant.

Cultivation principle: like shade, can be placed in a bright place indoors. The suitable temperature for growth is 18-25 ℃, 12-15 ℃ in winter, no less than 8 ℃. Sensitive to dry air, you should spray water frequently. It should be heavily watered in summer and keep the basin soil moist in winter.

From May to September, plants with good root growth can be fertilized once a week. In winter, if the plant is in a warm living room, thin fertilizer can be applied once a week.

Young plants change pots once a year, adult plants change pots every two years, and some old roots are removed. The basin soil can be mixed with rotten leaf soil, crushed clay and a small amount of rotten horse manure. Pad a broken tile at the drain of the basin to prevent the root from growing out of the basin.

Diseases and insect pests: aphids, shell insects, red spiders. Healthy plants are rarely infected, and once infected, the damaged branches should be cut off from the base and burned.

Longevity flower care: light is afraid of dampness, fear of waterlogging.

Selaginella officinalis, also known as soul grass, ferns, drought-resistant, even if the dry leaves hang down, as long as watered, it will come back to life. Like cool and afraid of the sun, the air humidity should be large. Can be inserted, with roots can live, very leather and solid.

Cacti are plants growing in tropical deserts, usually need to spray water properly, but in sunny conditions, do not spray water on cloudy days, some varieties can not be sprayed on the top of the grafting site, where water is easy to rot. The hole at the bottom of the flowerpot should be plugged with paper so that it can not only seep water (water will rot the root), but also prevent all the water from leaking.

Common sense of green plant maintenance

First, it is necessary to distinguish the requirements for light. Positive flowers: like sunshine, such as Magnolia, rose, pomegranate, plum blossom, pansy, Scutellaria barbata, etc. Neutral flowers: light requirements are not strict. Such as jasmine, sweet-scented osmanthus, brocade, etc. Negative flowers: such as asparagus, tortoise back bamboo, green apple, rubber tree, bamboo, dragon white tree and so on.

Second, according to the time required for light, it can be divided into 1. Long-day flowers: sunshine for more than 12 hours a day, such as iris, chrysanthemum, impatiens, etc. Sino-Japanese flowers: such as carnation, rose, etc. Short-day flowers: sunshine must be less than 12 hours a day. Such as poinsettia, chrysanthemum and so on.

Third, temperature 1. Hardy flowers: can withstand a low temperature of about 20 degrees below zero. Such as Yingchun, begonia, elm leaf plum, hairpin, cloves, day lilies, wisteria, etc. Semi-hardy flowers: can endure low temperatures of about minus 5 degrees, such as tulips, roses, chrysanthemums, pomegranates, peony, etc. Non-hardy flowers: such as asparagus, Magnolia, Magnolia, Euphorbia angustifolia, poinsettia, Fusang, calla lilies, magnolia and succulent plants.

Fourth, the important position of water in flower cultivation. Pay attention to water quality: according to the amount of magnesium salt and calcium, it is divided into hard water and soft water. Soft water is better for watering flowers. Rain Water is the most ideal, followed by river water and pond water, remember: do not use dishwashing water or water with washing powder, tap water should be hung for a day, so that the chlorine in the water is fully volatile. two。 Pay attention to the temperature of the water: don't get cold and hot. 3. Water quantity: more in spring, suitable for noon watering; summer foot, suitable for early and late watering; less watering in autumn; watering once every few days according to the dry and wet of the basin in winter. 4. Watering should be noted: according to different seasons, different weather, plant preferences to control. In short, before watering, first intuitively analyze the situation of water shortage, and then watering.

Fifth, growing flowers should also pay attention to the soil not to harden and harden. To increase the application of organic fertilizer; 2. Proper mixing of sand; 3. Drain and loosen the soil.

Sixth, family flower cultivation is often used in the production of retting fertilizer, such as grass, fallen leaves, straw, etc., adding appropriate amount of water, animal feces, human feces and a small amount of lime to grow square into the pit, covered with soil and retted for a certain period of time, which can not only kill insects and weeds, but also make the organic components decompose quickly.

7. Topdressing 1. Extra-root topdressing; 2. Urea topdressing, can also be sprayed with urea water foliar; 3. Potassium dihydrogen phosphate is beneficial to flower bud differentiation, and can also make flowers large and colorful. For iron-deficient yellow leaves, spraying ferrous sulfate is the best. Such as camellia, mast flower, Michelia, etc.; 5. Boron water can prevent falling buds, which is good for improving the number and quality of flowers. 6. Attention must be paid to the amount of topdressing. Urea and potassium dihydrogen phosphate are 0.2% Murray 0.3%, ferrous sulfate 0.3% Murray 0.5%, boron 0.05% Murray 0.1%. 7. The time of topdressing is usually 8-10:00 in the morning or evening, do not ignore the spraying on the back of the leaves.

8. in the prevention and control of diseases and insect pests in family flower cultivation, we should grasp the principle of "giving priority to prevention", strengthen management, and pay attention to maintenance work such as ventilation, light transmission, watering and fertilization, so as to make flowers and trees grow and strengthen their ability to resist diseases and insect pests. Once diseases and insect pests are found, measures should be taken as soon as possible to achieve "early treatment, small treatment, and treatment" to prevent spread. Examples of common diseases and insect pests in flowers are introduced as follows:

1. Insect pests (1) aphids are small blue-yellow insects that harm almost all flowers and trees. Between spring and summer, often concentrated in rose, pomegranate, oleander, chrysanthemum and other new shoots or buds. Sucking liquid juice with mouthparts will cause the young leaves to curl and atrophy, which will not only affect the growth and flowering, but also wither the plants. Aphids can produce 20 million 30 generations a year, and eggs can survive the winter.

The control method was sprayed with 3000 times of 40% dimethoate emulsion (that is, 3 kg of water added to 1 gram of dimethoate emulsion), or 1000 times of imidophos emulsion. In addition, there are two simple methods of prevention and treatment: one is to soak 5 grams of cigarette butts in the proportion of 70-80 grams of water, soak for 24 hours, knead slightly, filter out the dregs with gauze, and then spray them; the other is to use washing powder water (soap liquid water) of 1-100%. In order to improve the effect, a few drops of vegetable oil can be added, stirred fully, and sprayed with a sprayer when there is no oil on the surface.

(2) Spodoptera litura is commonly known as Caterpillar and itchy spicy seed. This pest bites on leaves such as rose, magnolia, peony, pomegranate, plum blossom, lotus, rose and so on. When seriously injured, the leaves of the whole pot of flowers were eaten up in less than a few days. The diamondback moth lurks on the back of the leaves and is often ignored if it is not careful. There are two generations in a year, once in early June and once in late June, and cocoon overwintering after mid-October.

When there are few pests and light harm, the damaged leaves can be removed and burned. Spray 90% crystal trichlorfon 1200 times (that is, 1 kilogram of water added to 1 gram or more of trichlorfon), or 50% fenitrothion emulsion 500 rain 800 times.

(3) the spider mite is also known as red spider. Often harm azaleas, roses, a string of red, begonia and real cypress, kumquat, generations, cactus, cypress and so on, of which azaleas and cypresses suffer the most. The leaf mite is small and red, so it is difficult for the naked eye.

See. Like to absorb juice on the back of the leaves, the injured leaves turn yellow, there are many small white spots, and soon wither and yellow fall off. The reproductive ability of spider mites is very strong, which can occur for more than 10 generations a year, and often breeds in the environment of high temperature and low humidity.

The control method removes the weeds in the basin and eliminates the overwintering eggs. When damaging, 40% dimethoate emulsion 1000 / 1500 times (that is, 1 kilogram of water added to 1 / 1.5 grams of dimethoate), or sprayed with 40% dicofol emulsion 2000 times.

(4) longicorn beetles are also known as stem borer and heart borer. It often harms grapes, azaleas, peaches, apricots, plums and so on. The control method cuts off the damaged tree trunk, captures and destroys it. Or use a knife to remove insect dung and sawdust, inject omethoate 1:50 liquid from the hole, and then seal the hole with mud.

(5) the beetle is also known as Bombyx mori and Bombyx mori. Its larvae are called grubs and their feeding habits are very miscellaneous. They are the main underground pests of many kinds of flowers. Winter ploughing and deep ploughing can promote the death of the overwintering dynasty. During the active period, 50% marathon emulsion will be irrigated 800 times as much as you wish to protect your natural enemies.

2. Disease

Powdery mildew, also known as powdery mildew, harms rose, rose, big-leaf yellow poplar, kumquat and so on, and often harms the leaves, stems and stalks of flowers and trees. A layer of white powder appeared on the injured surface, and the leaves withered when the disease was serious. This disease is easy to occur in a hot, humid and unventilated environment.

Control methods can be sprayed with topiramate, carbendazim and other agents.

(2) White silk disease harms rose, jasmine, magnolia, pomegranate, peach leaf coral, orchid, chrysanthemum and so on. At the time of the disease, the base of the stem was brown and rotten, and the mycelium was silk-like, initially white, and then turned yellow to brown. The disease often occurs in the middle of summer when the soil is moist, rainy and hot.

The prevention and cure method basin soil should disinfect, at the same time pay attention to the environment ventilation, avoid planting too dense, trim the diseased branches. Spray 50% carbendazim wettable powder 500 times before onset.

(3) Leaf spot is also called black spot, brown spot and so on. It is harmful to rose, camellia, rhododendron, rose, chrysanthemum and so on. First, black spots appear in the middle of the leaves, and then the leaves turn yellow and fall off. The causes are mostly caused by muggy, unventilated and humid environment.

The prevention and control methods should pay attention to improve the environmental conditions, and the damaged leaves can be removed and burned at the beginning of the disease. 1% Bordeaux solution can be sprayed for prevention and control, once every 7 days, for a total of 5 times during the whole growing period.

How to raise rose flowers, the culture methods and matters needing attention of Chinese rose / Chinese rose / four seasons flowers

Rose (scientific name: Rosa chinensis Jacq.), known as the queen of flowers, also known as "moon red", is an evergreen, semi-evergreen low shrub, flowering four seasons, usually red, or pink, occasionally white and yellow, can be used as an ornamental plant, can also be used as a medicinal plant, also known as rose. There are three natural varieties, modern rose flowers are diverse, single and double, and beautiful flower patterns such as high-heart crimping; its colors are bright and rich, not only red, pink, white and other monochrome, but also mixed color, silver edge and other varieties; most varieties have fragrance. There are many varieties of rose, there are nearly ten thousand in the world, and there are more than a thousand in China.

The natural flowering period is from August to April of the following year, and the flowers are large, from inside to outside, divergent and full-bodied, which can be widely used in horticulture and cut flowers. Rose has strong adaptability, cold resistance and cold resistance, regardless of ground or potted plants. it is suitable for beautifying courtyards, decorating gardens, arranging flower beds, planting hedgerows and flower racks. Rose cultivation is easy, can be used as cut flowers, used as bouquets and various flower baskets, rose flowers can be extracted essence, and can be used as medicine. It also has good antifungal and synergistic antifungal activity. Red cut flowers have become one of the necessary gifts between lovers, and become the theme of love poetry.

China is one of the places of origin of rose. Rose Rong is beautiful and varied. It often blooms at 04:00 and is very popular. 52 cities in China chose it as the city flower, and the rose in May 1985 was named the fifth of the top ten famous flowers in China.

Growth habits of Chinese rose

Although the requirements of rose on climate and soil are not strict, it is more suitable for loam which is loose, fertile, rich in organic matter, slightly acidic and well drained, and likes the environment of warmth, sufficient sunshine and air circulation.

The optimum temperature of most varieties is 15-26 ℃ during the day and 10-15 ℃ at night. Dormancy occurs when the winter temperature is below 5 ℃. Some varieties can withstand low temperatures of-15 ℃ and high temperatures of 35 ℃. When the summer temperature lasts more than 30 ℃, it enters semi-dormancy and the plant grows poorly. Although it can also conceive buds, the flower petals are few, the color is dim and dull, and the ornamental value is lost.

Key points of planting Chinese rose

Line spacing

The roses planted in the open field have developed roots, rapid growth, strong plants, small flowers and high ornamental value. the cultivation measures are selected according to different types, growth habits and geographical conditions in management. the planting density of upright varieties is 75 cm x 75 cm. The plant row spacing of expansive varieties is 100 cm x 100 cm, that of longitudinal varieties is 40 cm x 50 cm, and that of rattan varieties is 200 cm x 200 cm. The distance between plants planted in the rose is 50-100 cm, depending on the size and needs of the seedlings.

Soil

The cultivated land in the open field has high topography, plenty of sunshine, good ventilation and slightly acidic soil. Turn the soil deeply during cultivation and apply organic fertilizer as base fertilizer. Potted rose flowers should use sandy soil rich in humus and slightly acidic and fertile, but not alkaline soil. Before the new buds sprout in spring every year, the basin soil should be changed to facilitate its exuberant growth, and the change of soil will help blossom in the same year. Rose flowers can be planted in flowerpots of various materials, and earthen pots are naturally possible. The preparation of nutritious soil should pay attention to drainage, ventilation and the combination of various nutrients. The ratio is garden soil: rotten leaf soil: Rice chaff ash = 5:3:2. Before and after overwintering every year, it is suitable to turn the basin, trim the root, change the soil, and increase the basin diameter year by year, especially the mud tile basin.

Light

Rose flowers like light, there should be plenty of sunshine in the growing season, and there should be at least 6 hours of light every day, otherwise, only leaves will not blossom, even if the flower buds are formed, the flower color is not bright and fragrant after flowering.

Watering

Watering rose flowers is fastidious, to achieve dry see wet, do not dry do not water, watering is thoroughly. Rose flowers are afraid of flooding, there can be no stagnant water in the basin, the water is too big to rot. In the middle of summer, water should be watered once a day, and it can be watered when the surface of the basin soil turns white. Winter dormancy period must be less watering, keep semi-wet. Rose watering varies from season to season. Keep the soil moist and dry during winter dormancy. The branches grow before the beginning of spring, the branches and leaves grow, increase the amount of water appropriately, and irrigate once every morning and evening. Need to increase the amount of water in the growing season and flowering season, high temperature in summer, the amount of water evaporation increases, plants are in a weak semi-dormant state, the most avoid drying and dehydration, watering once every morning and evening to avoid sun exposure. When watering at high temperature, a small amount of water should seep out from the bottom of the basin each time, indicating that it has been watered thoroughly. Do not splash water on the leaves when watering to prevent diseases.

Overwintering

If you have warm conditions at home in winter, it is best to keep the room temperature above 18 ℃ and have more than 6 hours of light every day. If there are no measures to keep warm, then let it sleep naturally. When it comes to the Beginning of Winter's season, after the leaves fall off, only 5 centimeters of branches are left in each branch, and all the branches more than 5 centimeters are cut off, and then the flowerpots are stored in a cool place of about 0 ℃. The pot soil should be a little dry, but not too dry to prevent drying to death.

Fertilizer application

Rose flowers like to be fat. Potted rose flowers should be fertilized frequently and watered with light fertilizer every ten days during the growing season. No matter what kind of fertilizer you use, remember not to overdo it to prevent fertilizer damage and damage the seedlings. However, fertilization is not allowed during the dormant period in winter. Rose likes fertilizer, and the base fertilizer is mainly slow-acting organic fertilizer, such as rotten cow manure, chicken manure, bean cake, oil residue and so on. Adding liquid fertilizer and water every semimonthly can always keep the leaves thick, dark green and shiny. Before sprouting in early spring, thick liquid fertilizer can be applied once, no fertilizer should be applied at flowering stage, liquid fertilizer can be applied again after blooming in June, medium liquid fertilizer can be applied again when the fourth or fifth axillary bud is about to sprout in September, and rotten organic fertilizer can be applied to overwintering in December. Winter ploughing can apply human dung and urine or sprinkle with mature organic fertilizer, and then turn it into the soil, fertilize frequently during the growing period, and apply 1-2 times of quick-acting fertilizer after flower fade. Thin fertilizer should be applied in high temperature and drought, the last fertilizer should be applied before winter, and weeds should be removed in time before fertilization.

Pruning

Cut off the dry buds after blooming. When the flower buds first appear in the month, choose one of the well-shaped buds to stay, and cut off the rest. The aim is to leave only one bud for each branch, so that in the future the flowers will be full and bright, large and fragrant. A full pruning must be carried out after the blooming of the first period of each season. It is generally appropriate to trim lightly, cut off the blooming residual flowers and thin, crossed and overlapping branches in time, leave stout and young branches only 3-6 cm from the base, leave lateral buds, trim into a natural happy shape, make the plant beautiful and prolong the flowering period. In addition, potted roses should choose varieties with short, multi-flowered and rich aroma.

Summer pruning is mainly to cut off the sprouting flowers of grafted rootstocks, cut off residual flowers with leaves after flowering and remove excess buds, so as to reduce nutrient consumption and create good conditions for next flowering. In order to make the plant shape beautiful, you can cut off 3 or half of the long branch, 1 inch of the middle branch and 1 cm above the leaf. If the pruning is too light, the plant will grow taller and taller, the branches will be longer and thinner, and the flowers will bloom smaller and smaller. Winter pruning depends on varieties and cultivation purposes, and branches should be kept during pruning, and attention should be paid to the overall shape of the plant. Large flower varieties should leave 4-6 branches, select one side to grow strong buds with a length of 30-45 cm, cut off their upper branches, and vine or vine varieties should remove old techniques. cut off weak branches, diseased branches and cultivate the trunk.

Ventilation

Whether it is courtyard cultivation or balcony cultivation, we must pay attention to ventilation. With good ventilation, rose flowers can grow healthily and reduce the occurrence of diseases and insect pests.

Temperature

Rose flowers like a cool and warm climate and are afraid of high temperatures. The most suitable temperature is 18-28 ℃. When the temperature exceeds 32 ℃, flower bud differentiation will be inhibited. Therefore, in the summer when the temperature is high, the rose usually does not blossom, and even if there are a small number of flowers, they are much inferior to those at room temperature. In high temperature, the flowerpot can be moved to a cool environment for maintenance.

The mode of propagation of Chinese rose

Grafting method

Wild rose is commonly used as rootstock for grafting, which is divided into bud grafting and branch grafting. The survival rate of bud grafting is relatively high, which is generally carried out from August to September, and the grafting site should be as close to the ground as possible. The specific method is to make a T-shaped incision in the skin with a bud grafting knife on one side of the stem branch of the rootstock. Then select buds from the middle of the branches that grow well in the same year. After inserting the buds into a "T"-shaped incision, tie them with a plastic bag and give proper shade so that they can heal after about two weeks.

Sowing method

That is, sowing and breeding in spring. It can be sown in holes or in trenches, and it can usually sprout and sprout in the first and middle of April. The transplanting time can be divided into two types: spring planting and autumn planting, usually after the defoliation in late autumn or before the sap flow in early spring.

Split-plant method

Ramet propagation is mostly carried out in early spring or late autumn, the method is to dig up the whole rose belt soil for ramet, each plant has 1 or 2 branches and slightly with some fibrous roots, planted in the basin or open field, it can bloom in the same year.

Cutting method

Generally, when roses are dormant in early spring or late autumn, mature branches with 3 to 4 buds are cut for cutting. If softwood cuttings, shade properly and keep the seedbed moist. It can take root in 30 days after cutting, and the survival rate is 70% to 80%. If the rooting powder is dipped in the branch when cutting, the survival rate is higher.

Strip pressing method

Generally carried out in summer, the method is to bend the rose branch from the matrix and press it into the soil, peel off the bark of the lower half of the branch in the middle of the branch, expose the end of the branch, and wait for the branch to produce adventitious roots and new leaves, and then cut off with the mother.

Prevention and control of common diseases and insect pests in rose flowers

Spodoptera litura

The larvae of Plutella xylostella, Spodoptera litura, Plutella xylostella, Plutella xylostella and Plutella xylostella are mainly the larvae of yellow diamondback moth, green diamondback moth, brown diamondback moth and flat diamondback moth. Prevention and control method: once found, it should be sprayed immediately with 90% trichlorfon crystal 800x liquid, or with 2.5% fenvalerate EC 1500.

Shell worm

There are mainly white wheel scale, Japanese tortoise wax scale, red wax scale, brown soft wax scale, blow cotton scale, bran shield scale, snake eye scale and so on, which is characterized by sucking the juice of tender stems and young leaves of rose, resulting in poor plant growth. it is mainly induced by high temperature and humidity, poor ventilation and poor light. Control method: during the peak incubation period of nymphs, 2000 times of prolactin wettable powder can be sprayed and killed.

Aphids

They are mainly rose aphids and peach aphids, which absorb the sap of young organs of plants, harm tender stems, young leaves and flower buds, and seriously affect the growth and flowering of plants. Prevention and control method: spray with 2000 times of imidacloprid wettable powder in time.

Rosa trifoliata

Mostly in the larval stage, dozens or more than a hundred clusters harm, which can eat up the young leaves of the plant in a short time, leaving only a few main leaf veins, seriously endangering the normal growth of the plant. Prevention and treatment: a small number of potted plants can pick leaves with a large number of larvae and trample them to death. It appears in large quantities and can be sprayed with 4000 times of phoxim EC.

Cinnabar spider mite

Mainly copper green beetle, black velvet beetle, white star beetle, small blue and white beetle, etc., often eat new leaves, shoots and buds with adults, seriously affecting plant growth and flowering. Prevention and control method: make use of the false death of adults to vibrate and kill in the evening. Make use of the phototaxis of adults, trap and kill with black light. When adults feed, spray with 1000 times 50% malathion EC.

Heart-drilling worm

The rose heart driller is the larva of the rose stem wasp, which has wormholes in the stem and gnaws into the stem, causing the branch to break and the upper part to die. The larvae are white, with a yellowish head and a body length of about 15-17 mm. The adult has wings, a black body and a yellow belly. Pupa scarlet. It usually occurs one generation a year and causes damage from May to June. It pupates in the stem and overwinters. It is a kind of harmful pest.
