What to do with the growing insects of Cymbidium? pest control of Orchid / three insect pests and four diseases

No matter what plant it is, as long as it is kept indoors, it will inevitably be disturbed by diseases and insect pests. In the cultivation method of Cymbidium, we introduce that Cymbidium has to go to soil, light, temperature, fertilization and so on, and once these requirements are not up to the standard, Cymbidium will get sick and grow worms, what about the worms? In fact, it is very simple, just find the cause and solve it. The following is the prevention and control of diseases and insect pests of Magnolia. Let's go and have a look.

First, what if the magnolia grows bugs? spray them with medicine

Most of the beauty of the magnolia is reflected in the leaves, so once the worms get sick, the leaves will wither and yellow, and the ornamental value will seriously decline. What about the worms? In fact, it is very simple to spray. As for what medicine is used, it depends on what kind of insect it is. Next, let's take a look at the pest symptoms and solutions of the magnolia.

(1) the pest symptoms of Cymbidium and its solution.

1. Scale insects

As one of the main insect pests of flowers, shell insects naturally also infringe on magnolia. It mainly lives in groups in leaves and leaf sheaths, prickling and sucking juice, resulting in withered and yellow leaves and poor plant growth. In addition, they are also vectors for the transmission of plant viruses, so the insect must be killed quickly when it is found.

Solution: when there are few shell insects, brush them off with a brush, or wipe them off with wet gauze, or wash them with water; when there are too many shell insects, spray 1000-1200 times of omethoate EC to the leaves, spray once every 7-8 days, and solve the bug 2-3 times in a row.

2. Rat woman

Rat woman, also known as tide worm, watermelon worm, it is also one of the pests of orchid, mainly invading the root and stem of orchid, causing stem fester. This insect mainly harms the root and stem of Magnolia, causing stem engraving and ulceration.

Solution: when the above symptoms are found, florists should immediately spray 30% monocrotophos mixture 3000 times on the flowerpot, ground or plant. If you want to avoid this bug, you should keep the greenhouse clean and remove excess bricks, weeds and all kinds of debris.

3. Nematode disease

Another kind of insect that invades the magnolia. It is a kind of tiny animal with a body length of less than 1 inch. After being attacked by this insect, the orchid will grow poorly, the plant will be short, the leaves will shrink, and even die at an early stage.

Solution: after the above symptoms are found, it will be very effective to spray with dibromochloropropane, carbofuran, mirabilone and other drugs.

(2) the disease symptoms of Cymbidium and its solution.

Gentleman orchid long bug how to do, read the above content we should know how to deal with it! However, in addition to being attacked by insects, the disease also endangers the orchid all the time. The common diseases of the orchid are brown spot, white silk disease, anthracnose and soft rot. The specific symptoms and solutions are as follows:

1. Brown spot

The disease is one of the main diseases of Cymbidium, it mainly harms the leaves, the symptoms are: dark green watery spots at the initial stage, then expand into a round or irregular shape, sunken in the center, reddish brown to grayish brown, and the texture is harder than anthrax.

Solution: from the initial stage of the disease, 40% nail cream copper wettable powder 600-700 times liquid or 64% germicidal alum wettable powder 500 times liquid, once every 10 days, continuous prevention and treatment 1-2 times.

2. White silk disease

The disease is not common, but once suffering from the disease, the harm to the magnolia is very great. Symptoms: at the initial stage, the stem near the root appeared water-stained brown irregular spots, cortical soft rot, followed by white silk mycelium spread in the rhizosphere soil surface, the later stage into a small sclerotia, and finally color rapeseed-like, expanded to the whole base rot and necrosis.

Solution: always pay attention to observe the soil surface and find that the white bacteria line is picked out and burned. In the early stage of the disease, the disease can be solved by pouring 50% carbendazim wettable powder 500 times on and around the base of the plant stem, once a week, 2-3 times.

3. Anthrax

One of the main diseases of Cymbidium, it mainly harms the leaves. Symptoms: the disease spot is round or nearly round, the center is gray-white, sunken, the edge is dark brown, penetrating both sides of the leaf, showing a thin film, or even perforation. On the disease spots on both sides of the leaves, occasionally there are conidia with small black spots as pathogens, and most of them are pink myxospore clusters, especially under wet conditions.

Solution: after finding the above symptoms, you can use 50% methyl thiophanate (methyl thiophanate) wettable powder 700 times liquid, add 75% chlorothalonil wettable powder 700 times solution or 36% methyl thiophanate suspension 400-500 times solution, once every 7-10 days, continuous prevention and treatment for 2-3 times can be cured.

4. Soft rot

Another common disease of Cymbidium, it mainly harms leaves and stems, and when it is serious, the whole plant rots to death quickly. Symptoms: dark green watery spots appeared in the leaves, which gradually expanded and spread, and the stem infection spread upward to the whole leaves and downward to the roots. In serious cases, almost all the leaves fall and rot, and if the seedlings are young, the whole plant will die soon.

Solution: after finding the above symptoms, agricultural streptomycin 200ppm plus 20% toluene topazine wettable powder 1000 times solution, once every 7 days, continuous prevention and treatment for 2-3 times.

How to raise the Ten elements of the growth of Cymbidium

Ten factors for the growth of Cymbidium

Taking care of gentleman orchids; whether to live to see the water, whether to look good and fat, and to raise orchids meticulously and slowly are the essence of orchids.

As most people know, it is not easy to raise a gentleman orchid to die, and it is even more difficult to raise it well. it takes nearly four years for a gentleman orchid to grow and bloom from sowing to flowering. Daily maintenance should have many links, such as suitable environment, soil change, watering, fertilization, light control, temperature, humidity, temperature difference control, ventilation and so on. If you neglect any of them, it will directly affect its normal growth.

However, it is certain that the magnolia has strong vitality and strong ability to adapt to the environment, such as Put a gentleman orchid on cool and damp land or in an indoor toilet for 100 days, it will not die and can still grow, but some people like to take good care of it and raise it to death, which shows what it means. People all know that plants can not grow without soil, light, temperature, water, fertilizer, etc., if there is too much water, the root will rot and die if there is too much water, and the root will drown without water, without fertilizer and without fine products. Fertilizer will burn to death. If the light is too strong, it will die in the sun, it will not grow below 10 degrees, it will dormancy if the temperature is higher than 35 degrees, and the temperature will freeze to death if the temperature is below zero, so it is necessary to understand its habits and physiological characteristics in order to raise it well.

I. growth environment

Magnolia grows in the tropical primitive rainforest of South Africa, which is like spring all the year round, with a perennial temperature of 10-25 degrees and humidity of more than 60%. There is an obvious temperature difference of 8-10 degrees between day and night, and the soil is natural humus. Rain Water is moist, clean and ventilated, and grows in the shade of astigmatism trees. now people move it indoors or in a flower cellar to cultivate it, which is necessary to create a similar natural environment for him to return to nature. Only when he can grow healthily, can his appearance and characteristics be revealed.

2. Potted soil

Soil. It is the basis of the growth of Magnolia, the prerequisite for the cultivation of Magnolia, the prerequisite for the growth of Cymbidium, the nutrient soil originally grown in the South African rainforest humus, so the man-made nutrient soil must be close to the soil composition in the natural environment, loose, fertile, breathable, leached, adapted to the growth of fleshy roots, and its main medium materials, like leaves. (humus soil) ingredients include fresh pine needles, buckwheat bark, charcoal powder, pebbles, etc. Humus soil 80% pine needle 10% buckwheat skin 5% charcoal powder 3% pebbles 2%. The above is the proportion of nutrient soil of orchid, and the proportion of humus soil of seedlings should be larger, which is beneficial to the growth of seedlings. Different seasons in spring and autumn, the proportion of ingredients is also different, in line with the principle of tight spring and autumn, summer high temperature ingredients to add more, fast drainage, quick drying block wet, conducive to protect the roots, but also prevent running. Changing soil in autumn to keep more humus soil, more nutrients are conducive to Arrow flowering and reproduction.

Third, water, whether to live or not depends on the water

1. Function

Water is not only a necessary condition for plant survival, a raw material for photosynthesis, but also a carrier for absorbing and transporting nutrients. Nitrogen, phosphorus, potassium and other chemical elements in the soil can be absorbed by the roots of the plant only when they are dissolved in water. The organic matter produced by leaves must be dissolved in water before it can be transmitted to the various organs and tissues of the plant. Water is an important component of the plant. If there is no water, the plant will wilt and the leaves will droop and die. The PH value of water is required to be neutral, that is, the PH value is 6.5-7.

2. What kind of water is best to water flowers

Magnetized water, Rain Water, snow water, river water, well water, tap water (tap water must be trapped to release chlorine for three days before it can be used) stagnant water and dirty water can not be used

3. Principles

Watering principle; see dry and wet, watering thoroughly, can not be too dry, can not be too wet, too dry will make the root atrophy in case of water will rot, dry cultivation is not equal to dry maintenance, the limit of dry cultivation is that the root can not shrink, basin soil dry can not exceed 2 days, otherwise the soil will inversely absorb root water, so that the root atrophy, and can not be too wet for a long time, over-wet soil hypoxia will rot the root. The humidity limit is related to the season and temperature. The temperature and water demand is large in the growing period, which is normally watered once in 5-7 days, and must be watered once in 2-3 days in the growing period. Excessive humidity in the high-temperature period can play a cooling role. The roots are easy to rot when the low temperature, disease period and dormant period are too wet for 5-7 days, and the soil is slightly moist. Better dry and serve dampness

(4) Water is reflected in basin soil.

The main results are as follows: (1) the soil water content in the flowerpot is different, generally dry and wet. The surface of the basin soil is very dry.

Dry, but the middle of the basin is wet, down to the bottom is still wet. Especially large flowerpots over 8 inches

The law of water in basin soil is that the first stage is fully wet during watering-the second stage is upper dry-middle tide-lower wet-the third stage is upper and middle dry-lower moist-the fourth stage is all dry-water supply, and the second and third stages are the most suitable for the growth of Cymbidium.

(2) Detection method

Carry by hand; very heavy is all wet, not light is not heavy; upper dry-middle tide-lower wet, moderate humidity, lighter; upper and middle dry-lower moist, very light has been thoroughly dry. Watering is needed at this time.

(3) Gentleman orchid soil is very special, the main ingredients are rotten leaves, pine needles, buckwheat skin and other very leaking water, look at the bottom leakage has been thoroughly watered, in fact, do not worry, do not water half of the water, must be repeatedly irrigated, especially dry soil, large pots need to be repeatedly irrigated, in addition, regular basin immersion irrigation

5. Watering cycle reference

Seedlings, small pots, sunny days, high temperature, arrows, peak growing season, exuberant roots, good soil permeability to shorten watering cycle

Cymbidium, cloudy day, large basin, low temperature, high humidity, bud maturity, morbid condition and poor soil permeability all prolong the cycle.

Chenglan likes to be dry and young seedlings like to be wet. The amount of water should be strictly controlled at low temperature, and dry rather than wet.

6. large and medium-sized pots are watered differently.

In the same situation, small pots dry faster than large pots, and those with good soil permeability dry faster than those with poor soil permeability, and the water demand of high temperature is higher than that of low temperature. the normal growing period is 12-inch basin for 3 days, 20-inch middle basin for 5-6 days, and 28-inch large basin for 7-10 days.

Under normal circumstances, small and medium seedlings need a large amount of water, and when irrigating, there is a lot of big blue soil, the water content is high, and the bottom is not easy to dry.

7. Alternation of dry and wet

That is to say, dry and wet alternate with each other. But it is not absolutely copied, the humidity during the growing period is higher, and it is slightly dry at other times, but the dryness and wetness cannot be excessive, and the combination of penetration and impermeability. Can not always penetrate, still less can not always be permeable, the total permeable nutrient shunt is unhappy. Normal large pots will not dry for 7-10 days.

8 、. Watering season

The time of watering is related to the season. There is heating in the north in spring and winter. The temperature is higher from 9 to 15:00. The temperature is the lowest in the morning. It is best to water it in the morning. It should also be flexibly controlled according to the changes of season, climate and temperature. It should be too big in spring, frequent in summer, water must leak, take away mold, dry and wet in autumn and winter, watering should be strictly controlled before and after stopping air supply in the northeast, and dry rather than wet should be controlled. at the same time, it is also necessary to check the lack of water in individual carriers every day.

9. Adult orchid "does not pour white water

Add a little liquid fertilizer at a time. It is good for the growth of Cymbidium, and it is famous for increasing the thickness and intensity of leaves. (high temperature dormancy is not added)

10. Water temperature and soil temperature watering

Watering should also pay attention to the water temperature, the water can not be too cold, about 20 degrees is better. This is very important. The fleshy root of Cymbidium is most afraid of cold. When excited with cold water, it is easy to get sick and rot. The water temperature should be close to the soil temperature, and the temperature difference between the two should not be too large. Watering time is appropriate in the morning and evening. The temperature difference between flowers and water is large, which is not conducive to the growth of flowers.

11. Plant watering

Seedlings can be irrigated throughout the plant, which is conducive to the growth of seedlings. Orchids, arrows and arrows can not be irrigated by the whole plant. Watering should avoid the heart of flowers, which is very easy to cause rotten heart and rotten arrows, with serious consequences.

12. Watering time

The suitable watering time is 7-8 in the morning. watering with high temperature at noon and large water with cold and hot temperature difference is very harmful to the growth of flowers. watering in the evening does great damage to the roots of flowers, and the roots of flowers are perishable by soaking them for more than ten hours without light.

13. Spraying water conservancy on leaf surface and surface layer and its disadvantages

The water must be clean, otherwise it will pollute the leaf surface and spray water on the leaf surface, (1) increase the surrounding humidity (2) the surface spray water is beneficial to the root of the orchid hair, (3) when the surface spray water is high temperature, it is beneficial to cool down (4) keep the page clean and enhance photosynthesis.

High humidity of foliar spray is beneficial to bacterial infection and induces the occurrence of leaf spot disease and anthrax.

Will pollute the leaf surface, the leaf surface will leave water stains, need to clean to remove water stains, trouble

14. Summer watering

Watering orchid safely in summer is the key: watering frequently, and watering is not only an effective means of cooling and increasing oxygen, but also the basic skill of safely spending summer. Some people say that if the gentleman orchid is not dry or watered, it should be dry and thoroughly watered. This statement is not correct. Once dried, the fleshy root is damaged, and it is difficult to recover after the damage. At the same time, it is difficult to water thoroughly after it is dry, and once it is thoroughly watered, it will either run or rot. The hotter and drier the weather is, the more attention should be paid to "watering" and watering thoroughly.

15. Do not pour half a section of water

Gentleman orchid watering is very easy to water half of the water, it seems to water through the bottom of the water, in fact, it is not, it is a false penetration phenomenon, in fact, the gentleman orchid soil is very special, relatively loose gap is large, water will be lost with the gap, continuous leakage. The basin soil will not be thoroughly watered for six times, so it is necessary to be patient in watering the orchid, slowly watering it through many times (verify the method of watering thoroughly, using a toothpick to remove the topsoil to check). If you can't water thoroughly for a long time and pour half a section of water, the orchid will rot, and the deformation will seriously affect the normal growth of the orchid.

16. Accumulate over time

Some people say that it is difficult to water orchids and watering for three years. Watering is a crucial link in orchid cultivation. When, how much, thoroughly or leaking, the season is different, the growing period, the temperature is suitable, the high temperature period is not too long, the low temperature and dormant period is not less than ten and a half days, the growing period is completely different from the dormant period, the growing period can be watered with heavy water, and there can be no shortage of water. During the high temperature dormancy period, it is better to dry than wet, the water will rot the roots, the plant size requires different degrees of dryness and humidity, the orchid is easy to dry, the seedlings are easy to wet, the seedlings are no more than 5 days in 2-3 days, 7-10 days in the orchid, the watering is not the same, the temperature and florescence are different, the watering during the fruit setting period is different, the soil moisturizing degree is different, the watering is also different, the watering position of flowers is also different, the light is sufficient, the ventilation is good, the basin soil is easy to dry. Watering is also different, the same pot of gentleman orchid watering 365 days throughout the year is completely different, for example, 12-inch basin high summer temperature for 2-3 days, maintaining humidity is conducive to cooling, growing water demand for 3-5 days is not too small, low temperature, dormancy for 7-10 days is not less. Therefore, watering magnolia can not be clearly explained in a few words, nor can it be explained in books. It can only be understood and controlled by the accumulation of practical experience over time.

17. The watering method of Magnolia; basin soaking and basin watering

The most scientific way to supply water to gentleman orchid

First, sitting basin soaking, this method is especially suitable for family care, family care plants are few, even the flower cellar boutique orchid is also soaked in the basin. Sitting basin soaking has several advantages: 1, the root of the plant receives water evenly, 2, the source of no waste, 3, less soil loss, 4 less nutrient loss, fertilization should be soaked in the basin, receive fertilizer evenly, and the soaking standard is until the top soil of the basin soil is wet.

Second, sit in the basin to irrigate; fill the basin with water, put the flowerpot into the pot for continuous watering, use a toothpick to remove the topsoil and check the edge of the water until it is thoroughly watered.

Third, water control; move the irrigated flowerpot to the spare rack to control water, and then connect it and recycle it without wasting resources.

Fourth, fertilizer, whether it is good or not, and the essence of raising a gentleman's orchid lies in the use of fertilizer.

No fat, no high-quality products, fat little immortal orchid, fat will harm the flowers, precision is just right to see the true merit

In the process of growth and development, Magnolia needs a large number of nutrient elements, once the lack of these nutrients, there will be stunting, and the content in the soil alone can not meet the needs of the plant. it is necessary to rely on artificial supplement to provide reasonable nutrients such as nitrogen, phosphorus, potassium and other nutrients to make the plant grow healthily and as you wish. The key to orchid cultivation lies in the use of fertilizer, what fertilizer to use, what fertilizer to use at that stage, and how much to use. This is the essence of raising merit.

2. Nitrogen fertilizer is the main component of protein in the plant of Cymbidium. It is the most basic substance that makes up the plant. Without nitrogen, it is impossible to produce protein and protoplast. Nitrogen is the main raw material for chlorophyll, and chlorophyll is necessary for photosynthesis. Therefore, the nitrogen supply is good, the plant growth is exuberant, the leaf is broad and thick, the color green plant is strong, the fruiting rate is high and the grain is full. Under the condition of nitrogen deficiency, the plant grows slowly, short and thin, the leaves are narrow and thin, the flowering period is late, the fruit setting is few, and the bottom leaves turn yellow. However, when the nitrogen fertilizer is applied too much, the leaves become soft and thin, and droop, the disease resistance is weakened, and diseases and insect pests are easy to occur. The principle of proper amount of nitrogen fertilizer must be mastered in the application of nitrogen fertilizer in Magnolia. The commonly used nitrogen fertilizers are: rotten bean cake, sesame seeds, sesame seeds, fish water, kickhorn, blood is also a better nitrogen fertilizer. These fertilizers must be fully fermented and mature for two years before they can be used.

3. Phosphate fertilizer is the main component of cytoplasm and nucleus of Cymbidium. It can promote cell division and reproduction. It makes the new roots and seedlings develop and grow faster, the adult orchid plants blossom early and bear more, the grains are full, and phosphorus can enhance photosynthesis. Phosphorus can make the stems and leaves tough and enhance the disease resistance. When the plant is deficient in phosphorus, the roots and seedlings grow slowly, making the old leaves of the stem become purplish red or dark green. Affect the growth and development of reproductive organs. There are delayed flowering, few fruit grains, not full and other phenomena, the commonly used phosphate fertilizers are: bone meal, fish scales, bone, rice bran and so on, fermentation, ripening can be used.

4. Potash fertilizer is one of the most abundant elements in the plant of Cymbidium. Potassium exists in the state of potassium carbonate and is soluble in water. Potassium fertilizer is also called root fertilizer, which can promote the absorption of nitrogen and the formation of protein. Potassium can promote the activity of enzymes, accelerate sugar synthesis and starch accumulation in plants, increase the content of fiber in plants, promote the development of vascular, and enhance the strength of mechanical tissue of cell wall. It can make the leaves thick and upright, the veins clearly protruding, and improve the quality of varieties. When lack of potassium, the leaves are soft, the veins are not prominent, the old leaves are prone to chloasma, and then the leaf tip and leaf edge will also appear brown spots, brown and withered, showing scorched and strong. But it should not be excessive, the excess leaves turn yellowish brown and inhibit plant growth.

The potash fertilizers commonly used in gentleman orchids are: plant ash, charcoal ash, rice husk ash and so on.

The growth of Magnolia can not be separated from the three elements of nitrogen, phosphorus and potassium. Nitrogen fertilizer mainly promotes the rapid growth of plants, luxuriant leaves and broad leaves, which plays an obvious role in the growth of leaves. Phosphate fertilizer mainly promotes bright flowers, full fruit, high fruiting rate and early flowering. It has obvious effect on flowers and fruits. Potash fertilizer can increase the rigidity of leaves, promote the growth of root system, and has obvious effect on root system. Nitrogen, phosphorus and potassium are the necessary nutrient elements for the plant of Cymbidium, and each has its own unique function, which can not replace each other, and should be applied in combination with each other.

5. Potassium dihydrogen; it is to obtain quick-acting fertilizer with fast fertilizer effect and short duration. If applied improperly, it can produce side effects such as burning root and yellow leaf. Try not to use it as far as possible, occasionally foliar spray supplement can be used, or carry out a small amount of trial to gain experience and reuse, seedling foliar spraying effect is good, but the dosage must be small, otherwise it will burn seedlings, just the opposite

6. Seasonal fertilizer

High temperature in summer, a large amount of fertilizer decomposition, generally not lack of fertilizer in summer, only hypertrophy, hypertrophy, burning root hair, need to be washed with water, summer high temperature July-September temperature exceeds 30 degrees, plants will dormancy and stop growing, so re-fertilizing plants will rot and die. Thin fertilizer can be applied frequently in spring growth season, autumn and winter dormancy ends when the weather turns cool, and the root system is basically solid after a month of soil change. You can pour some liquid fertilizer in the right amount, and at the beginning, the amount of fertilizer should not be too large, because the solid fertilizer is still working, the interval is longer when you start pouring liquid fertilizer, and the interval in the later stage is gradually shortened (about 15 days).

7. Stage use of fertilizer

The two-leaf and five-leaf seedlings should be applied thin and frequently, once every 15 days, and the middle seedlings should have 6-13 leaves, enter the rapid growth period, keep up with the fertilizer and water, and replace some liquid fertilizer each time, blowing arrows, pregnant buds and flowering before and after flowering. As a result, a lot of nutrients are needed. Need to supplement phosphorus and potassium fertilizer, about once every 10 days.

8. No fertilizer taboos; no heavy fertilizer, no chemical fertilizer, high temperature, low temperature (above 30 degrees), dormant period (below 15 degrees), no fertilization in weak period, no fertilization in new soil for 20 days, no fertilization in seedling stage, no fertilization in a leaf seedling, no fertilization at noon (about 25 degrees), no fertilization without light, no fertilizer without fermentation, otherwise, it is easy to cause leaf tip leaf edge scorch and root rot. (because the unripe soil will ferment for the second time in the basin, causing the flower soil to heat up about 50 degrees quickly and burn the roots.)

9. Fertilization method

Must be diluted with water (animal retting 30-40 times plant retting 15-20 times) to do basin soaking, basin soaking is the first choice, because it is fertilized evenly and does not hurt the roots. Irrigation causes loss and waste, second, uneven fertilization, application of base fertilizer, edge fertilizer, methods; combined with soil change to stir-fried pockmarked seeds. The sesame seeds are buried at the bottom. Or the upper part of the root, remember that the fertilizer should not come into contact with the root, otherwise it will burn the root.

10. Absorption

Due to the biological characteristics of Cymbidium, fleshy root, absorption area concentrated in the new root hair root tip hair, so too fierce, too thick he can not bear, the root hair is easy to burn and fall off, lose the absorption function, so supplement fertilizer for Cymbidium, it must be fully fermented soft and easy to absorb.

12. Fertilizer application amount

Apply thin fertilizer frequently, small seedlings at 50:1, medium seedlings at 40:1 and orchid at 30:1

Interval; 15-20 days (growing period)

13. Notice when using fat.

(1) the nutrient supply of potted Magnolia is mainly guaranteed by artificial topdressing fertilization. Different fertilizers are applied in different seasons and different growth stages. (a) combined with soil exchange in autumn and adding oil crops such as sesame seeds and sesame seeds as solid fertilizer, it has the characteristics of long-lasting fertilizer effect, slow and uniform fertility release, oil plants will also make the leaves shine, (b) appropriate and timely replenishment of liquid fertilizer, lack of what, artificial control.

(2) Light, when fertilizing in autumn, winter and spring, we must choose sunny weather, plants can fully decompose and absorb nutrients under photosynthesis, if low-temperature plants can not decompose and absorb nutrients without light, at this time, fertilizer supply is very easy to cause fertilizer damage to rotting roots.

(3) Cymbidium grows normally as long as the temperature is suitable, and it does not have the function of self-absorption and regulation, that is to say, as long as you apply fertilizer, I will absorb it, grow slowly at low temperature and grow fast at high temperature, so it is easy to grow in summer (running strips). Scientific control and application is very important, otherwise improper fertilization, leaves will be uneven length, width, thickness, fat leaves become wider and thicker. Leaves are also easy to wrinkle, fat and small, leaves become narrower, change books, but also lead to non-flowering or flowering without fruit.

(4) Cymbidium is an herbaceous flower with fleshy roots and is easy to rot. Whether soybeans, pockmarked seeds or animals are retted, they must be fermented before they can be converted into substances that plants can absorb, otherwise, they will have no effect at all. on the contrary, they will burn roots and rot roots due to the second fermentation heat in the pot. and growing mosquitoes pollute the indoor air.

(5) when retting liquid fertilizer is added to orange peel, the aromatic tincture in orange peel can improve some fat odor. It is also a fertilizer after decay and fermentation, which is beneficial to plant absorption. It can also increase acidity and improve the PH value of flower soil.

(6) fertilization with dry soil moisture. Fertilization in moist soil is easy to spread in soil, and the effect is good.

(7) Potash fertilizer is the first priority for root cultivation. If the root is well raised, all appearance will be revealed, and gold will shine. Proper supplement of potash fertilizer, due to the growth of flowers, but not excess, surplus will inhibit flower growth instead.

(8) fertilization must be stopped during the period of low temperature below 10 degrees, high temperature above 30 degrees, dormant period from July to September in summer and disease period. The normal fertilizer deficiency stage of Magnolia is the two growth periods and bud need to supplement fertilizer, other stages do not need to supplement fertilizer.

13. Pertinence of fertilization

(1) nitrogen fertilizer

It is mainly used for flowers and seedlings less than three years old to make their leaves stout, wide, thick and bouncing lines. It is not easy to apply adult orchid before budding (December-January) to prevent only sterile buds.

(2) phosphate fertilizer

Apply before pregnant bud to promote the formation of flower bud, at this time also need a certain amount of potash fertilizer.

(3) potash fertilizer

It is mainly applied after flower pollination, focusing on ensuring the formation and growth of fruit embryos. Do not use too much, or it will inhibit plant growth.

(4) the use of bone powder must increase the permeability of flower soil and should not be in direct contact with flower roots. Use a little at the bottom of the flowerpot, cover the soil before planting the flower, and then apply a little more on the edge of the pot when the soil is buried in the root of the flower. It is not easy to burn roots in this way.

(5) short-leaf varieties should not add hemp seed base and edge fertilizer, but add thin and thin fertilizer every 15 days.

(6) it is better to increase the base fertilizer less than to increase it more, which will solidify the soil, because liquid fertilizer can be applied in normal management.

(7) there are not many orchids at home, so it is best to use sesame oil and water as fertilizer. A pot of flowers, 100 milliliters of oil a year is enough. Use sesame oil to water the flowers for hygiene. The best time to fertilize is during the growing period, usually from the beginning of May to the middle of September, every two weeks. "

(8) understanding of fat. It is determined by four factors: light, water, gas and temperature. In other words, the fertilizer in the soil can be decomposed and absorbed by plants only when the microorganisms are active and under the condition of good light, temperature, water and air permeability. So that he can have enough to eat, drink well and look as good as people want.

The balance of fertilizer is very important. No matter how much nitrogen is applied, your blue will not be absorbed without potassium.

Retting of water and fertilizer

1. Liquid fertilizer must be retted by itself, know yourself and know the enemy, and can be classified retting according to the main proportion of nitrogen, phosphorus and potassium, which is easy to use, high nitrogen content in sesame, sesame seed, soybean, blood and kickhorn, bones and fish scales. Bone meal contains high phosphorus, plant ash and charcoal ash contain high potassium.

In comprehensive retting, bone, kickhorn, bone meal, plant ash, sesame, sesame seeds, soybeans are retted together, retting proportion, 10 barrels of boiled sesame, sesame seeds, soybeans each 1000 grams of plant ash wood charcoal ash 2000 grams of pig hoof bone, can also add fish scales, kick horn blood, bone desalination, all kinds of waste oil, waste milk, etc., comprehensive fertilizer must be retted for more than two years. Comprehensive fertilizer is usually used the most, the utilization rate is the highest, can be retted some more, more than two barrels is better. Recycling retting to produce never-ending fertilizer

2. The main point of water and fertilizer retting is that it must be fully fermented, preferably after freezing in winter and drying in summer, it can be fully fermented for more than two years, dark brown, no foul smell, light liquid, no strange smell, and the odor dissipates quickly when in use. (no fermented odor exists for a long time) adding orange peel, apple peel edible vinegar and koji wine can improve and reduce the odor. It can also increase acidic substances and adjust the ph value of flower soil, showing weak acidity.

3. Retting tools with round plastic buckets with two covers of 5 inches. Put retting items in buckets with water, preferably in places with high temperature under light. Before use, open the lid for 10-20 days. When in use, animals, 50:1, plants, diluted with water at 30:1, are basically odorless and harmless.

5. Lighting

Light is the most important condition for the growth of Cymbidium. Cymbidium is a very light-loving plant, the longer the light time, the better the growth, the more sufficient the light, the lighter the leaf color, the higher the blue quality and various parameters, the plate is hard, striped, straight and straight. if the light is less than 3 hours, the plant indicators will be greatly reduced, obviously soft, dark, no lines, black, light demand.

The light demand of different varieties is different, the color orchid is weaker than the green orchid, the light color orchid is weaker than the dark color, the mature orchid is weaker than the small seedling, the annual seedling is very strong to the light adaptability, the light can restrain the seedling growth, the growth period is suitable for water and fertilizer, the light is weaker than the two years, the mature orchid is weaker than the three years, and the sunshine time can be increased during the gestation bud and flowering period.

The light intensity is inseparable from the temperature, and the chlorophyll of the orchid with sufficient light at 10-20 degrees will increase under photosynthesis, and the photosynthetic efficiency is the highest when the temperature is between 20 and 30 degrees. When the temperature exceeds 35 degrees, the photosynthesis tends to stop. If you don't hide the light at this time, the leaves will burn and die in the sun.

Plants mainly rely on light and action to produce nutrients during the day, and grow nutritionally at night, with long days and short nights in summer. The utilization of nutrients is not high, which affects the growth of plants. Proper shading can shorten the light time and let plants accumulate nutrients effectively, which can more effectively ensure the growth of Magnolia and control the running of strips.

Magnolia grows in tropical rain forest astigmatism, the sun can not directly shine on the leaves, artificial cultivation should control the light, summer high temperature light intensity 8-16:00 must be shaded, spring. 10:00-14:00 in autumn also needs shading. From mid-September to June, there can be all-weather light. In the two peak growing seasons, from September to November to March-May, the sunshine time is more than 8-10 hours, and the temperature is between 15-25 degrees. Temperature and light are suitable for the rapid growth of Cymbidium.

Second, the lighting angle determines the upright angle of the leaves. If you want the leaves to stand upright, you should not only have oblique light, but more importantly, there should be a top light. Increase the light area of leaves and enhance photosynthesis. The leaves will be upright and upright, and it will be greatly reduced if there is no top light to pull the leaves upright. The leaves of Magnolia are highly phototactic and are in phase with sunflowers, so the upright degree of the windowsill is not as upright as the flower cellar, but it lacks the top light to pull.

VI. Temperature

Cymbidium is a semi-positive flower, which is sexually fond of weak light, warm and humid, clean and pollution-free tropical rain forest, with an annual average minimum temperature of not less than 15 ℃ and a maximum temperature of not more than 25 ℃. The growth organs of Cymbidium adapt to this lukewarm, humid and warm natural environment.

(1) when the temperature exceeds 32 ℃, it will dormant and stop growing, and the organs will naturally enter a dormant state.

When the temperature drops below 10 ℃, the growth and development of the plant is slow, and the mutated leaves will grow. When the temperature is below 5 degrees, the growth and development will be inhibited and stop growing, and when the temperature falls below 0 ℃, it will freeze to death.

(2) the state of leaf growth is also different at different temperatures. In summer, high-temperature leaves are easy to grow, that is, thin, thin and long. The new leaves in spring, autumn and winter, especially in winter, are wide, thick and short. Controlling temperature is the key measure to raise orchids.

The temperature also has a great influence on the flowering period, the temperature is too high, the flowering period is short, the temperature is low and the flowering period is long. The florescence may last for 15-20 days when the temperature is above 30 ℃ in summer. In winter flowering period, the flowering period can reach more than 30 days when the temperature is 10-15 ℃. The most suitable temperature for flowering period is 15-25 ℃.

(3) the suitable temperature is different for different sizes of Cymbidium plants. The seedlings require a higher relative temperature. This is because the seedling is small, the growth power is strong, the high temperature is beneficial to the rapid growth of the seedling stage, the temperature difference needed in the seedling stage is smaller, the seedling growth temperature should be controlled at 20-30 ℃, the new leaves should grow slowly below 15 ℃, the annual seedling, the temperature should be controlled at 20-25 ℃. For plants over two years old, the temperature should be controlled at 15-25 ℃. Adult orchid, especially in the winter arrow season, the temperature can be between 10-25 ℃, artificially caused a large temperature difference, which is very conducive to the flower running arrow, does not produce the phenomenon of arrow entrapment.

(4) temperature has a direct effect on photosynthesis and respiration. In the adaptive temperature range, the metabolic function of the plant is related to the temperature. When the temperature is high, the metabolic rate accelerates the plant growth, but when the temperature is low, the metabolism is slow, the plant growth rate also slows down.

7. Temperature difference

Even the difference between the highest temperature and the lowest temperature in the care environment also refers to the temperature difference between day and night. Temperature difference can make the plant adjust the rate of nutrient absorption, which is more beneficial to the growth and development of the plant. It is beneficial to the full absorption of nutrients in the leaves of Cymbidium. It is beneficial to the accumulation of various nutrients, and the temperature difference is one of the main conditions for the growth of Cymbidium. The most suitable temperature difference is 6-10 degrees between day and night, and the temperature is controlled between 15-25 degrees. The most suitable temperature for Cheng Lanshang arrow is 10-20 degrees. A large temperature difference is favorable for archery. If there is no 8-10-degree temperature difference, the gentleman orchid will clip 80% of the arrows.

Windowsill, balcony maintenance and flower cellar cultivation of the gentleman orchid is often very different, flower cellar temperature difference is large, and windowsill temperature difference is small. Especially in winter, there is little temperature difference between the windowsill and orchid. The plants cultivated in the flower cellar are better than the windowsill in terms of leaf brightness, color and lustre, and the leaves on the windowsill all deviate in luster, color and fineness, and are easy to clip arrows, while there is almost no arrow in the flower cellar, but it is certain that the gentleman orchid cultivated by the windowsill and balcony is shorter and harder than the leaves maintained by the flower cellar (the balcony is better than the windowsill).

8. Humidity

The best humidity is 60-80%. The orchid originally grows in the tropical rain forest, and the relative humidity is relatively high. according to this characteristic, if you want to raise the orchid well, you must create a rain-like environment, and often spray water to keep the humidity at 60-70%. Especially the indoor environment is relatively dry in winter, more attention should be paid to spring. Autumn. Summer can't be ignored.

When the humidity is high, the blue is bright, while the humidity is small and waxy.

The humidity of the gentleman orchid is the key to the family care, and the delicate brightness of the leaves is good. The head width of humidity can reach the best state, and the evaporation of plants can be balanced with humidity. Raise the root. Only with strong roots can the leaves grow luxuriantly.

If the humidity is 40% lower, spray water to humidify it.

The leaf brightness and fineness will be better when the relative humidity is 60%.

When the humidity is more than 80%, the transpiration of Cymbidium leaves will be greatly inhibited, and the following situations will occur.

1. It is easy to rot roots, hearts and leaves.

2, easy to breed mold, various leaf spot, anthrax and so on.

3. Affect pollination and fruit setting at flowering stage.

4, it is not conducive to the bounce pattern on the leaf surface and the formation of wax film (bright).

IX. Ventilation

Magnolia grows in a well-ventilated tropical rain forest. If you want to raise a good orchid, you must create a good ventilated environment before it can thrive. The root is strong and hard, the leaf is tall and straight, the gentleman orchid most avoids muggy and unventilated, especially in the hot summer, the bacteria in the high temperature basin soil propagates rapidly, the basin soil is seriously lack of oxygen, and the fleshy root will rot in 3-5 days, but it is not the more ventilated the better. Gentleman orchid is more avoid cold wind, convection wind. Spring breeze can not be blown directly, some high temperatures in summer are blown by fans, but not directly to the leaves, but can be blown under the flowerpot, 1 can play the role of environmental cooling, 2 pots of soil can also cool down, which is beneficial to the growth of magnolia.

Ten nourishing merit

It is often said that three-thirds of varieties and seven-part cultivation are more important than dry cultivation, and dry cultivation is not the same as dry cultivation, which is controlled by the essence of soil, fertilizer, water, light, temperature and humidity.

(1) to cultivate merit, that is, to fully understand and master the growth habits of Cymbidium, to artificially create a similar natural environment of warmth, slight tide and suitable light, and to accurately control the whole process of watering, fertilization and soil change. it is also necessary to skillfully master the techniques of cultivation, reproduction, breeding and breeding, so that the quality, character and appearance of different varieties of Cymbidium can be fully reflected.

(2) Modern magnolia grows, multiplies and evolves under the action of man-made factors. It can be said that a good variety only has the basic conditions to become a high-quality orchid, if it cannot be matched with excellent nourishment, great water and fertilizer, the leaves will become wider, the veins will be widened, the lines are not protruding, the plates are not thick and the shape is not good, and various indicators will be greatly discounted. If coupled with excellent nourishment, a perfect combination of internal and external factors, then the cultivation of fine orchids is not an extravagant hope. It is certain that high-quality goods are experts, on the contrary, although the cultivation is excellent, but the variety is general, it is impossible to produce high-quality products, general varieties, coupled with low maintenance skills, the cultivation is nothing more than unfashionable products.

(3) it is necessary to have "three minds": concentration, mediocrity and perseverance. Concentration is the premise of good orchid cultivation, ordinary mind, doting, seeking speed, will be contrary to one's wishes, the combination of orchid cultivation and spiritual cultivation, perseverance: to cultivate a good variety can not be achieved in 3muri-5 years, you must persevere, only by becoming an expert, can you get twice the result with half the effort and get what you want.

(4) Orchid cultivation trilogy; Ailan understands orchid recognition orchid-orchid view orchid appreciation orchid-health and mind cultivation is leisurely and enjoyable among them, orchid cultivation must first cultivate its mind before it can become a positive fruit how to raise a pot of high-standard gentleman orchids

First, cultivate high-quality magnolia

Friends who have just entered the orchid world will often hear the words of a hundred schools of thought. After a period of time, they will find that there are different views, and some theories contradict each other, leaving themselves at a loss as to what to do and blindly. A little carelessness is easy to be misled or even fooled. How can I take a shortcut on the road of playing orchid? Through my own practice, I have summed up the following experiences:

(1) to cultivate merit

Cultivation is mainly reflected in soil allocation, fertilization, watering and disease prevention. It is the basic work of playing orchid, no matter how good orchid you can't raise well, you can't show the status quo it should be. After decades of practice, the elders of Lanjie have summed up a lot of successful experience. On the basis of summarizing the experience of my predecessors, I have developed a set of simple and easy to learn-"Fool raising method".

1. The formula of culture medium

Cymbidium is a semi-aerial and semi-water rooting plant, so the water permeability of the culture medium is very important, and most of the rotten roots of many friends are caused by large water. My recipe is:

Broad-leaved soil 30%; coniferous soil 30%; sand 15% wood carbon 10%; dehydrated bone particles 5%. Among them, the sand is the size of sorghum rice, the size of charcoal is the size of corn, the bottom of the basin is charcoal and bone grains with a diameter of 1 cm, and the pelvic waist is filled with bone grains.

The characteristics of this formula are that it is not easy to store water, good air permeability, short dry and wet cycle, easy to root; phosphorus and potassium fertilizer and trace elements are saturated and do not need to be replenished at ordinary times.

2. Watering

According to the above formula cultivation of the gentleman orchid, the watering method is very simple, no matter what season, when you see the basin soil surface dry 1 cm, it is best to use trapped water.

3. Fertilization

Fertilizer should be applied according to the principle of balance of nitrogen, phosphorus and potassium. Most of the leaf channeling we see is caused by excessive nitrogen fertilizer, except for the variety. Like a slim person, it is a reason that you give him big fish and meat every day. How can we achieve a balance? This is a very complicated problem. Through my research, I found that using charcoal as potash fertilizer and defatted bone particles as phosphate fertilizer does not burn roots, and putting a large number of media into the culture medium does not produce side effects on the growth of Cymbidium. Therefore, in the allocation of soil, let phosphorus and potassium fertilizer in a state of saturation, so in nitrogen, phosphorus, potassium these three unknowns, phosphorus and potassium into a constant, thus simplifying the complex problem, usually only give nitrogen fertilizer on it.

So how to give nitrogen fertilizer? How can I be sure of how much? There are three main methods to supply fertilizer: solid base fertilizer, liquid water fertilizer and foliar fertilizer, and the usual method is burying base fertilizer and watering fertilizer. I think: from the point of view of easy to control the amount of fertilizer, watering fertilizer is better than burying base fertilizer. because the concentration of nitrogen fertilizer produced by retting is different for each person, there is no unified standard, so we can only find out the best ratio of fertilizer and water by talking about concentration test, based on the principle of not burning roots. Remember that it is better to have less than more! In addition, fertilizer should be given every four seasons, once every semimonthly, so as to maintain the stability of leaf growth.

4. Disease prevention

The diseases of Cymbidium are mainly insect pests and bacterial pests, which should give priority to prevention. Every time an appropriate amount of "bacteria and insect pests" is added to the fertilizer and water, effective prevention can be achieved. Usually, you only need to use a brush to deal with cotton insects.

The above are the main contents of the "Fool cultivation method", which is characterized by simple daily management, no rotten roots, good roots, not easy to occur diseases, and stable growth all the year round.

(2) Flower recognition

To cultivate fine orchids, we must first understand what is a good orchid. What kind of orchid is easy to cultivate high-quality orchid? To put it simply, the orchid whose comprehensive index is close to the top of the "top ten standards" is a fine orchid. This is very general. In reality, where do we start? How to get closer to this vertex? I put forward the "triple water theory" with the method of reverse thinking. According to the logic of raising, analyzing and solving problems, we call the orchid to be cultivated the ideal orchid, and then dissect its composition. First of all, the orchid quality of the ideal orchid should be the best, so which orchid is the best among the various varieties we see today? I think the technician is the best, which should tell us that the ideal orchid should have the ingredient of the technician; second, the ideal orchid has a good degree of standing, so which variety of orchid is the best at present? That is short leaves, so there should be short leaves in the ideal orchid; third, if the grain, head and seat of the ideal orchid are better, we will naturally think of the round head, that is to say, the ideal orchid should have a round composition. From this we can draw a conclusion that there should be at least three genetic components of short leaves, technicians and round heads in the ideal orchid.

At present, there are very few pure short leaves, pure technicians and round heads, even if most of them are algebraic for a long time and can not be used as the basic orchid. The orchid with high brightness, fineness, thickness and hardness should be selected as the basic orchid which contains short skills, short round skills and short round skills. The advantages of orchids containing these four combined genes complement each other, so that it is easy to cultivate higher quality orchids. In addition, technicians with high quality components will also show corpus luteum or flower body, which is more ideal.

(3) Powder

At present, the cultivation of new varieties is mainly carried out by means of sexual hybridization. The above four basic orchids are carried out in accordance with the principle of complementary advantages, and after the offspring are bred, choose the ideal basic orchid to be the next generation, and also cross or backcross according to the principle of complementary advantages, so that the quality of the orchid will continue to approach the ideal goal. If you need to stabilize the gene, you need to self-cross repeatedly, but it takes seven generations of 5muri to basically complete it.

Second, the cross experience of Magnolia.

It is best not to use Henglan as the male parent, Henglan itself is unstable, and there will be too many variations in the process of cultivation.

Most pockmarked faces walk through Henglan noodles.

The advantages of the male parent should outweigh the female parent.

To cultivate Huang short, it is necessary to use the technician as the female parent and the short leaf as the male parent. For example, if the short leaf is used as the female parent and the technician as the male parent, the cultivated offspring will also produce a small amount of yellow short, but the effect is not as good as that of the former.

Now good orchids are made of short leaves as female parents, and the hardness of the male parent must be stronger than that of the female parent in order to produce more offspring along with the male parent! Otherwise, go with the mother!

If the short leaf is pointed, the round head of the thick plate can be given to improve the head shape, but it is best not to give the round head flower face, because the genes are too miscellaneous! There are many varieties of flower faces, the variables of monks are more unstable, and the flower faces of technicians and dark orchids are more stable.

Now the so-called gaudy face is worthless in the northeast. Because the rigidity is poor, the orchid quality is poor, can achieve the Tiebei orchid quality flower face now too few! This is the reason why you can't see the flower face in the appreciation of famous and fine works. Now the flower face can only be used as an ornament, not as a parent! Also do not return to the monks, because the monks are poor in quality and rigidity.

The round-headed monk had better give short leaf powder! It can enhance the rigidity of the offspring.

The offspring of Tiebei short leaves can produce light-colored flowers and short leaves.

Without the descendants of technicians and oil craftsmen, high-quality orchids can never be cultivated. Technicians and oil craftsmen are not extinct, but have been improved. although the improved varieties have become wider and shorter, they are not as good as a generation in terms of orchid quality. now relatively pure technicians and oil craftsmen are rare. Relatively pure old technicians and oil craftsmen are genetically stable and are a necessary tool for directional training.

Technicians, oil craftsmen and short leaves cross each other, technicians, oil craftsmen as female parents, short leaves as male parents. The tips of technicians and oil craftsmen are hard to string off! Even if the round head string is used, it can not be removed at once, and the rigidity can exceed the technician's short leaf head, or the rigidity can exceed the technician's short leaf transformation. If the "Huang technician" as the father, the offspring are prone to face, so "Huang technician" can be called the father of the gentleman orchid. At present, most of the Huang technicians in the society are the N-generation hybrid seedlings cultivated by Huang technicians as their male parents, and purebred "Huang technicians" are very rare. To transform the irregular horizontal pattern of the technician, use a variety string with regular horizontal pattern, such as round head and short leaf.

Anshan orchid is a Japanese string, and there are many fine products, but the genes are unstable, wide and short, but lack of veins.

Japanese orchid is better as a female parent! The male parent had better be a national orchid with good rigidity, high brightness and protruding veins, because the Japanese orchid gene is stable, and the head shape and width of the female parent can be preserved. The purpose of lighting the national orchid is to take advantage of the brightness, vein pattern and rigidity of the national orchid.

If you use the national orchid as the female parent and order the Japanese orchid, the national orchid should not be too thick, and the plate is too thick to have an impact on rigidity. The board is too rigid, but the veins will not jump up. In general, the veins jump up, especially those out of the pit, the blades are thick, but the rigidity is poor.

If you want to come up with a high-quality Japanese string, it is recommended to use a good tattoo, highlight short leaves as the mother, and click the Japanese orchid, which can produce flowers similar to the Morningstar. Japanese orchid string as the female parent, to use strong rigidity, gluten jumping, bright national orchid as the male parent.

Young orchids from young orchids are more like their parents, while those from older orchids are more chaotic and atavistic. What I found is that the powder is older and the mother orchid is young, the older powder is genetically stable and has a high fruiting rate, while the young powder is unstable but has strong vitality when used as a mother orchid.

Third, the cultivation of Cymbidium

The Tiebei generation used Gong Zhanyuan as the female parent, Huang technician as the male parent, and the improved flower length decreased to 40 cm. The head shape is acuminate. The leaf width is 10 cm. The glossy wax veins are obviously concave, this is the Tiebeizhang generation, the disadvantage is that the leaves are long, not erect, and the head shape is not ideal. So after crossing with short leaves as male parents, the leaf drops to 35 cm, the flower shape is beautiful, and the head shape is sharp. The pulse crotch is not wide. The pigment is poor. This is the second generation of Tiebei. The third generation is the cross between the round head monk and the second generation Tiebei, the head shape becomes the most ideal oval shape. The fourth generation uses the third generation Tiebei flower face and the powder leaf of the monk drops to 30 cm. The leaf is 12 cm wide, the leaf surface is bright, the head shape is oval, the color is light green, and has the vein pattern of green veins and yellow ground. The plant is shaped like a fan, straight and elegant. Wax film flower face: by the "monk", as the female parent "Huang technician", as the male parent, the offspring selected by the hybrid combination. Its features: delicate orchid, large vein, light color, green veins, yellow or green veins, luster such as wax, dignified and elegant, green and delicate, giving people a refreshing feeling, with a high ornamental value. The degree of the face flower is related to the blue and color of the leaves of the male and female parents selected in the hybrid combination, and related to the light and humidity. The emergence of "wax flower face" has not only the congenital nature of hybrid combination, but also the acquired cultivation conditions of light and humidity, both of which are the secret of cultivating "wax film flower face". "Wax Film Flower face" is also an important index for the appreciation and evaluation of gentleman orchids. This is not an article by Mr. Yuan Qinglin of Japan:

"flower face" refers to the clear and obvious vein of the leaves of Cymbidium, and the distinct depth of the veins (refers to the mesophyll).

"Flower face" gentleman orchid, as early as the sixties has been published. Comrades Gong Zhanyuan, Liu Renduo, Zhang Wenyue, etc. Choose different characters of Cymbidium as female parent or male parent, cultivate many different characters of "flower face" Cymbidium.

The reasons for the emergence of "flower face" gentleman orchid:

In combinatorial hybridization, the leaf color of the selected female parent and male parent must be dark and light, so that their offspring will appear "flower face" due to the genetic results of their parents. Have plenty of light time. To have a certain degree of humidity.

There is also a controversial view: the thinner the mesophyll (or thick muscle) of the leaf, the brighter the "flower face" will be. The gentleman orchid said to himself:

1) before you adopt me, you need to know that my life is infinite and will never die, so some people call me longevity flower. But my puberty is only about 10 to 15 years, but I will continue to be with you with asexual budding.

2) Please give me time in advance when giving me orders, do not water or fertilize me indiscriminately, although I will certainly be resurrected, your patience and understanding will make me grow faster and more luxuriantly.

3) Please be kind to me, because I am the one who cherishes and needs your love most in the world. Don't cover me for too long and don't lock me up. I need ventilation and talk to you. Because, you have your life, your friends, your work and play, while I have only one friend.

4) talk to me often. Although I don't understand your language, I know your voice. You know how happy I am when you go home, because I have been waiting for your footsteps.

5) Please pay attention to your kindness to me, I will never forget it, if it is cruel, it may affect me forever. Even let me die.

Please don't hit me and scold me. Remember, I showed resistance, but I won't bite you.

7) before you scold me, please think that there may be something wrong with me. Maybe I am too dry, too wet, fat and deficient, barefoot and dark, too many bugs or fungi, too many worms or fungi, and too much substrate or water.

8) when I am old and no longer as cute as a baby or adolescence, please still take care of me, see a doctor, separate my budding, cut off my old stems and roots, and I will be reborn. Please still be nice to me, because we will all grow old one day.

9) when I am very old, when my health has passed away and I can no longer live a normal life, please do not try to keep me alive, because I am no longer able to live, I will continue to exist with my budding. I know you don't want me to leave either, but please accept the fact and be with me at the last minute. Please don't walk away by saying, "I can't bear to see it die," because at the last moment of my life, will be reborn in a new posture. I will always be with you.

The precautions of growing flowers in summer, the skills of growing flowers that will not die.

Flower bonsai network guide: today, the editor of the flower bonsai network is to share with you the matters needing attention about growing flowers in summer, so that the flowers will not die. Let's have a look at the flowers who like them.

Seeing that summer is coming and the temperature begins to rise gradually, the flowers at home should pay more attention to maintenance, otherwise they will have to die. But don't worry, flower friends. Today, Huahua will give you a focus on how to raise the flowers this summer in order to spend the summer safely!

Rose

As soon as the May flowering period is over, the summer is hot and rainy, and the rose is about to usher in a dormant and semi-dormant state. For the rose, the focus of summer conservation is to make the flowering plant grow strong, so that it can blossom for the next time as soon as possible.

1 shading and cooling

The soil of potted rose is limited, and it is easy to bask in the pot soil in hot weather, so it is necessary to shade and cool the rose. Today, Huahua will introduce you to several shading methods to let the rose at home receive scattered light.

1. Use a shade net or straw mat to cover the rose into a semi-shaded state, so that the ground forms a shadow, and the purpose of cooling can be achieved.

2. You can put a large flowerpot outside the flowerpot of the rose and add something like light stone and ceramsite between the bottom of the big flowerpot and the space between the two flowerpots, which can also play a cooling role.

2 watering and fertilizing

In the hot summer weather, the rose began to enter the dormant period gradually. But the rose is still blooming in summer, so it also needs fertilization, but the amount of fertilization is less than that in spring and autumn.

1. In summer, a thin liquid fertilizer can be applied at intervals of about 15 days. Liquid fertilizer can be formed from moldy soybeans or animal manure after soaking and sealing fermentation with water. The best concentration is more than 50%, which can meet the growth needs of Chinese rose.

2. The evaporation capacity is large in summer and can be watered once every 2-4 days. Watering rose water is best used after drying in the sun, which can reduce the temperature difference between basin soil and water. If you use ultra-cold water, it will stimulate rose roots and affect the normal development of plants.

3. in addition to watering the rose normally, you should also spray water on the leaves, preferably once in the morning and afternoon, before eight o'clock and after five o'clock in the evening. When spraying water, you can also add 0.2% potassium dihydrogen phosphate solution to make the rose flowers bright.

3. Pest control and disease control.

Summer is the high incidence period of rose diseases. Leaf spot, scale insects, powdery mildew and so on all occur in summer.

1. When the weather is hot, the floor of rose pots should be often sprayed with 15% quicklime or carbendazim or potassium permanganate solution to achieve sterilization and prevent the invasion of diseases and insect pests.

2. If the rose has been found to have powdery mildew and leaf spot, it can be sprayed with 0.3% stone sulfur mixture, once a week, about 2-3 times; if you find a small bug, you can immediately spray 800 times the enemy to control the disease and kill the eggs.

Geranium

With the advent of summer, whether geraniums can spend the summer safely is an issue of great concern to many flower friends. Just follow Huaxue and do these things, and you can keep your geraniums safe for the summer.

1 shading and ventilation

It is hot and muggy in summer, and if the air is not well ventilated, it is likely to cause the death of geraniums.

1. In summer, you can add some mulch to the basin soil of the geranium to reduce water evaporation, avoid the rise of soil temperature caused by direct sunlight, and isolate the bacteria on the surface of the basin soil. Blue stone and ceramsite can be used. Do not choose bark that is prone to bugs and airtight stones.

2. Geraniums should be properly shaded in summer. They can bask in the sun sooner or later. At noon, they should be transferred to the place where scattered light shines. Those placed by the window can pull down the curtains or add a sunshade net.

(author: Ly A Yi Source: geranium bar)

2 watering and fertilizing

The summer watering of geraniums is the biggest headache.

1, watering time is best in the morning or evening, wait until the soil temperature dropped before watering, watering should be hung for a period of time, so that the temperature of the water can be similar to room temperature.

2, there are many watering methods, do not use head watering, this can easily lead to water in the upper part of the flowerpot but the root system at the bottom of the pot does not absorb water, resulting in death, you can use the pot method to water to ensure the water demand of geraniums.

3. Pelargonium does not apply fertilizer in summer, because the dormant geranium can not absorb fertilizer at all, and may cause fertilizer to accumulate rotten roots.

(author: Ly A Yi Source: geranium bar)

3. Diseases and insect pests

Geraniums are also particularly vulnerable to diseases and insect pests in summer, and prevention work needs to be done in advance.

1. In order to avoid stem rot of geranium, carbendazim solution, root rot solution or potassium permanganate solution can be infused once a month to prevent bacterial infection. If the geraniums are found to have stem rot, they can only abandon the seedlings and soil.

2. If it is found that geranium has leaf spot disease, flower wilt and so on, the diseased leaves should be removed in time to prevent the spread of infection, and then spray Bordeaux solution for prevention and control.

Gentleman orchid

Gentleman orchid summer is basically in a dormant state, in order to let the gentleman orchid can safely spend the summer, Huahua for you to find a few points that must be paid attention to, flower friends must remember.

(author: Qiuhe speechless Source: gentleman Orchid)

1 shading and ventilation

Summer high temperature, gentleman orchid in a semi-dormant state, we must do a good job of heat prevention and cooling.

1. The gentleman orchid likes weak light rather than strong light, and is most afraid of direct sunlight, so it must be placed in a cool and ventilated place in summer so that it can see scattered light sooner or later.

2. The method of burying sand can be used to cool down. That is, to bury the magnolia and the basin in the sand, to bury the basin, and then spray water on the sand every morning and evening. By doing so, we can not only keep the basin soil moist, but also achieve the purpose of cooling with the help of the heat absorption of sand water evaporation.

2 watering and fertilizing

The watering of the gentleman orchid is also very important.

1. Because of the high temperature and evaporation in summer, the water demand of Cymbidium is relatively large. For 1-2 years of magnolia, about 5-7 days watering; more than 3 years of magnolia, but also according to the size of the flowerpot and the number of years to decide.

2. The water for watering the magnolia had better use the stored Rain Water. The tap water can only be used after 24 hours of precipitation to prevent the soil from deteriorating. If the drainage of the basin soil is not smooth and the stagnant water time is too long, it is easy to cause the succulent root system of Cymbidium to rot.

3. It is hot and rainy in summer, so fertilizer should be stopped to avoid rotting roots. If the orchid is placed in a cool and ventilated place, it will not be completely dormant, you can apply thin bean cake liquid fertilizer every 10-15 days, and keep the pot soil dry before fertilization.

3. Diseases and insect pests

Because the orchid is in the dormant period in summer and has poor ventilation, it is particularly vulnerable to scale insects. At this time, drugs such as scale must-cure or dichlorvos can be used to mix with water according to the ratio of 1 to 2000, and then sprayed on the leaves of the orchid and irrigated at the same time, which can effectively kill scale insects and other pests.

Longevity flower

With the coming of summer, the temperature has been rising. In the hot weather, how to maintain longevity flowers? Huahua will give you a detailed introduction.

1 shading and cooling

High temperature in summer, longevity flowers are basically in a dormant state, at this time the resistance of longevity flowers is relatively poor, the need for proper shading and cooling.

1. In order to reduce the temperature, you can spray more water on the ground. When the water evaporates, you can take away part of the heat. You can also spray water on the leaf surface to lower the temperature around the longevity flowers. Be careful not to spray too much when spraying water, otherwise it will easily lead to decay of longevity flowers.

2. In order to avoid strong light burning longevity flower leaves, shading treatment is needed in summer, shading net can be added, or longevity flowers can be moved to places with weak light.

2 watering and fertilizing

Long-lived flowers that are dormant in summer should pay attention to water control. Water control is to reduce watering, but must be irrigated, otherwise long-term drought will easily lead to root water shortage and death.

1. For people who grow longevity flowers indoors, water them once every 10-15 days to keep the soil slightly moist. If the water is too much, the fleshy roots of longevity flowers are easy to rot. For outdoor longevity flowers, it is OK to be moderately drenched in a light rain, but in case of heavy rain, move indoors in time.

2, longevity flower summer fertilization, the concentration should be low, basically thin liquid fertilizer can meet its growth needs, about 8-10 days, you can use rotten bean cake fertilizer or traditional Chinese medicine residue.

That's all for today.
