The method of Flower Culture of Cymbidium

Propagation and culture (1) Propagation: the method of plant division and sowing are mainly used. How did the gentleman orchid grow up? Magnolia usually uses only two methods of reproduction: one is sexual reproduction, that is, sowing and reproduction, and the other is the method of spreading ramets in asexual reproduction. Large flowers such as orchids are more commonly used for sowing and reproduction. The advantage of breeding methods is that they can be multiplied to meet the needs of many growers. However, artificial pollination must be carried out through the front board of sowing and reproduction. It is better to carry out different planting, and the pollination rate of different plants is very high. Robust plants can usually have a speed of 10 knots after being propagated by different plants; grain. The method of pollination is: when the flower splits for 2-3 days, when the bud matures and the stigma secretes mucus, that is the time for pollination. When pollinating, pick up the pollen of the stamens with a new brush and gently shake it on the stigma of the pistil. In order to improve the setting rate, pollination can be carried out every 9-10 hours and 2-3 p.m. The seeds mature after about 8-9 months. When the pericarp changes from green to dark purple, the ears can be cut off and the seeds can be peeled off after 10-20 days. Before sowing, put the seeds in warm water at 30-35 °C for 20-30 minutes, remove and dry for 1-2 hours. If you can soak them in 10% sodium phosphate solution for 20-30 minutes, remove them and wash them. If you soak it in clean water for 10-15 hours, it will be better. It can be planted in cultured soil. Place the planted flowerpot at a room temperature of 20-25 ℃, keep the humidity at about 90%, and germinate for about 1-2 weeks. To produce radicles. One of the tasks that must be accomplished in sowing and reproduction is to prepare the soil first. There are many materials that can be used to produce cultured soil, but one of the more easily available materials is to use loose soil, in which enough humus comes from the forest surface and mixed with clean fine sand. Magnolia prefers slightly acidic soil with a pH value between 6 and 6.5. The time required to propagate Cymbidium by sowing is not strict. It can be sown in spring, autumn and winter, but temperature is an important condition. It is better to sow seeds at a temperature of 20-25 °C to meet the temperature requirements of bacteria. . How do orchids reproduce asexually? The asexual reproduction of flowers includes cuttings, ramets, beads, grafting, etc., but the asexual reproduction of Cymbidium is usually based only on ramet methods. It is more common to use this method. In order to use the ramet method for reproduction, we must first do some preparatory work: 1 potted plants should be ready for potted plants. The basin is preferably a basin. Don't buy porcelain and ceramics because their surfaces are beautiful and their air permeability is poor. It is not conducive to the growth and development of plants. 2 prepare medium soil, it is better to disinfect. If fine sand is mixed with humus soil, humus soil should be sprayed and disinfected with potassium permanganate 1000-2000 times aqueous solution; fine river sand should also be washed and disinfected with boiling water to prevent seedlings from being infected by bacteria. 3 prepare a little charcoal powder to absorb moisture from the wound to prevent decay. 4 the knife is sharp, and then dry grinding (without water) is carried out on the grindstone for dozens of times, so that the knife body is highly heated and bacteria are killed. In the case of ramets, the mother plant of Cymbidium is first collected from the basin, and perennial buds can be found. If the daughter strain is born on the outer edge of the mother plant and the plant is small, you can hold the part of the bulb with one hand, hold the base of the seed plant with the other, and then tear off the sputum. Remove the seed plant from the mother; if the strain is thick and difficult to squat, it should be cut off with a prepared sharp knife. Don't be strong, so as not to damage the seedlings. After cutting the seeds, the wound should be immediately coated with dry charcoal powder to absorb liquid to prevent decay. Next, plant the seedlings on the pot. When planting, the planting depth should bury the false bulb at the base of the seed plant, the part of the seedling should be slightly higher, and should be covered with disinfected sand. Immediately after planting, pour the water into the water. After 2 weeks, after the wound healed, a layer of culture soil was added. It usually takes 1-2 months to produce new roots and 1-2 years of flowering. Cymbidium propagated by ramet method is relatively stable in heredity and can maintain various characteristics of the original species. (2) planting 1 soil: Magnolia is suitable for soil rich in humus. The soil has good air permeability, good water permeability, and is fertile and slightly acidic (pH6.5). Infiltration of about 20% sand into humus soil is beneficial to rooting. When growing, as the plant grows, the basin increases gradually. When planting one-year-old seedlings, use a 3-inch basin. In a good year, the 5-inch basin will be replaced. After every 1-1 to 2 years, the larger one will be replaced. Basins can be replaced in spring and autumn. 2 watering: the orchid has a more developed fleshy root, which stores [2] and a certain amount of water, so this flower is more resistant to drought. However, drought-tolerant flowers should not be seriously short of water, especially under the condition of high temperature and dry air in summer. Don't forget to water it in time. Otherwise, the roots and leaves of the flowers will be destroyed, causing new leaves to sprout and primitive leaves. Coke is estimated to not only affect flowering, but even lead to plant death. However, too much watering will rot. Therefore, we must master it and always pay attention to the dry and wet conditions of potted soil. It should be poured once when it is semi-dry, but the pouring amount should not be too much. It is right to keep the basin soil moist without tides. So, how many times do you want to pour it in a few days? In general, spring water once a day; in summer, you can use a fine spray can to pour the leaves with the surrounding ground on sunny days, twice a day; every other day in autumn; once a day in winter; watering once a week or less in winter. But it must be pointed out that this refers to the "general situation". Must be flexible to adapt to a variety of specific circumstances. For example, you need to pour more water on a sunny day; pour less on a cloudy day and pour it every few days; when the air temperature is high and the air is dry, you should pour it several times a day; if the flowerpot is large, because there is a lot of water stored in the soil, it will not be air-dried and can be watered less; if the flowerpot is small and the water evaporates easily, you should pour in the right amount of water. Flowerpots should be placed in a well-ventilated place that is easy to evaporate. It should be poured into the right amount; if the ventilation is poor, the evaporation rate is slow, and the air humidity is high, it should be watered less. Less watering is needed at seedling stage and more watering is needed at flowering stage. In short, it depends on the circumstances to ensure that the basin is soft, not too dry and too damp. Of course, it is better to use magnetized water; secondly, Rain Water in the river, snow or domestic water, again the water in the pond, and worst of all, tap water. If flower growers living in big cities only have tap water, you can put it in a small tank or basin and pour it in 2-3 days later. This will precipitate some harmful impurities in the water. In addition, the substances contained in the water can be oxidized and purified, and the temperature of the water can be close to the humidity of the potted soil, so that it is not too cold or too hot, and the plants will be damaged. Fertilization: many flowers are high in fertilizer, but the fertilization of high-fat flowers is also limited. Excessive fertilization, adverse growth, and even rooting or burning of plants. Magnolia also belongs to this type of plant and must be fertilized appropriately. The nutrients required by flowers are also different at different stages of growth and development. Therefore, different fertilization methods suitable for plant needs should be adopted in different periods. Such as fertilization, topdressing, extra-root fertilization. (1) Fertilizer (or base fertilizer). The aim is to create conditions for the growth and development of plants to meet their nutritional needs. Magnolia must be used when changing potted plants every 2 years. Commonly used manure (livestock manure), compost, green manure and bean cake fertilizer are applied to the soil. (2) topdressing. Mainly to promote the growth of plants. Orchids can be used as fertilizers, such as cake fat, fish meal and bone meal. At first, the application of planting was less. Subsequently, with the increase of plant growth and leaves, the amount of fertilizer gradually increased. When fertilizing, potted soil can be applied to 2-3 cm deep soil, but should be careful not to put fertilizer into the root system too much, so as not to burn roots. It is enough to use this solid fertilizer once a month. It should not be dense. (3) chasing liquid fertilizer. After chasing liquid fertilizer, the supernatant of soaked plants and plants is poured into 30-40% water, and then into the potted soil. Small seedlings should be 40 times of water, medium seedlings should be 30 times of water, and large seedlings should be 20 times of water. After pouring fertilizer, water should be watered every 1-2 days (the amount of water should not be too much), so that the fertilizer can infiltrate into the potted soil and give full play to the fertilizer effect. Do not water for 1-2 days before pouring liquid fertilizer, so that the potted soil will be drier and fertilized, which is more effective. Fertilization time is better in the morning; when pouring, fertilizer should be poured along the basin and be careful to avoid applying it to plants and leaves. In addition, fertilization varieties should also be applied according to different seasons. For example, in spring and winter, it is recommended to use some phosphate and potassium fertilizers, such as fish meal, bone meal and hemp cake, which is beneficial to the formation of veins and the improvement of leaf gloss; in autumn, properly apply some rotten animal hair, horns, hooves or bean cakes. Pour the extract into 30-40 times of water to promote leaf growth. (4) topdressing. Fertilization through this method mainly makes up for the lack of nutrients in the soil, solves the problem of lack of fertilizer in plants, and makes seedlings grow rapidly and flowers and fruits grow thicker. External fertilization uses a sprayer to directly dilute the plant's leaf surface, allowing nutrients to seep into the leaf tissue through epidermal cells and leaf stomata, and then transported to the whole body. Botany. The commonly used fertilizers are urea, potassium dihydrogen phosphate and calcium superphosphate. When spraying, spray evenly on both sides of the blade. Spray every 4-6 days during the growing season, every two weeks during semi-dormancy, usually after sunrise, and plants should stop after flowering. It must be pointed out that this method only found a lack of fertilizer for plants. Available only. If plants are nutritious and thrive, they should not be used.
