Growth habits and cultivation techniques of Cymbidium

First of all, it is necessary to understand the ecological habits of Cymbidium, which has important guiding significance for the cultivation of Cymbidium. The native place of Cymbidium is mostly on the top of the mountain or the upper part of the mountain, which is higher than other orchids. Rain Water is less, sunny, frosty and snowy, and the loam is barren in the forest and grass. The specific ecological environment here has developed its strong and developed roots, narrow and long leaves, thick and hard, rough, slow growth and other characteristics different from other orchid species. When Yamashita enters the orchid garden and the family is introduced and domesticated, it is relatively more difficult than other bluegrass, and it is easy to wither, wither leaves, fall seedlings, or even die the whole pot. To raise orchids well, the environment comes first. If we set up a living environment corresponding to its original place according to the ecological habits of Cymbidium and strengthen its management, Cymbidium will certainly be able to feed, grow, grow and blossom just like other orchids. According to the main habits of Cymbidium, the main points of cultivation of Huilan are discussed: 1. Huilan has an important habit of "fear the dark according to the happy sun". The original place of Cymbidium is mostly on the top of the mountain or the upper part of the mountain at a higher altitude, with plenty of light, as the ancients said, "Orchid gives birth to Yin, while Cymbidium produces Yang." Therefore, family cultivation of Cymbidium should pay attention to solving the problem of lighting and set up a similar ecological environment for it. Put the orchid basin in a sunny position facing southeast, so that it can enjoy plenty of sunshine all the year round. Except for summer and early autumn, shading nets should be used to cover the hot sun exposure around noon, other seasons can let the sun shine, in order to enhance photosynthesis, speed up the production of nutrients, and promote plant growth. Practice has proved that the sun can strengthen grass, promote roots, wide leaves, thick veins, shorter leaves and more flowering. If the light is weak, the cymbidium will be stunted. It is easy to pour grass but not easy to blossom. Only with the right light can bluegrass grow green and vivid. two。 Cymbidium has the habit of needing more nutrients than other orchids. The false bulb of Cymbidium is small, the storage of nutrients is relatively small, but the leaves are more and longer, and the nutrient consumption is correspondingly more. At the same time, the old seedlings are still sprouting new leaves, consuming more nutrients, and the crude plant material has poor water and fertilizer conservation. It is difficult to meet the needs of normal growth. In the natural environment, Cymbidium relies on its well-developed roots to absorb nutrients from the earth to meet the needs of its own growth. Orchid cultivation in nurseries and families is limited by flowerpots, which can not give full play to the advantages of developed roots, and the preferential conditions of nature have disappeared, so we must rely on more fertilization to supplement nutrients. Pot plants of Cymbidium require more fertilizer than other orchids. The fertilizer applied by Chunlan should be twice as thick as that of Chunlan, at the same time, various elements should be matched scientifically, thin fertilizer should be applied frequently, and it should rely on its own strong and developed root system to absorb nutrients in the plant material, plus appropriate extra-root topdressing (foliar spraying). If you can usually use potassium dihydrogen phosphate 2ram 1000 to prepare fertilizer solution to spray leaves. You can also use a glucose solution of 2gam1000, when the leaf seedlings are sprayed with water, which is quite effective. The effect of leaf color glowing, thickening and broadening was seen in 10 days. If the same level of fertilizer is applied to Cymbidium, it will not accelerate the breeding and growth of Cymbidium. For the old and weak, diseased seedlings, and cymbidium grass that has just gone down the hill, the main exception should be clean-up. 3. Cymbidium has the characteristics of thick and long roots, tall grass and high toenails. Therefore, potted Cymbidium is suitable for deep planting in large and deep pots to meet the growth requirements of orchid roots. It has been proved in practice that deep planting is better than shallow planting, and the new seedlings are strong and easy to bloom. 4. Cymbidium has a longer growth cycle than other orchids. Cymbidium grows slowly down the mountain, which is related to the poor soil quality of the original land. Second, the bluegrass dug down the mountain, the root damage is serious, after the mountain storage and transportation to multiple cropping time is long, nutrient consumption is large, vitality is greatly damaged. It must take quite a long maintenance cycle to recover. Generally speaking, it takes two to three years for new buds to mature in potted plants, and it takes more than one year for Cymbidium to enter the best growth period, and some even take two to three years to take pots, so it is advisable to turn the pots less after planting. Because the root system is easy to be dehydrated in a short period of time when turning the basin, relatively many roots will be damaged, and the combination of root and soil in the process of taking the basin also needs a relatively long process, so there will be a relatively long recovery period, therefore, we can not act in such a hurry, we should wait for the new orchid seedling to mature, grow the new root and then turn the pot, because it takes a long time to turn the pot, so we must replace the new plant material and ensure the fertilizer supply of the plant material. 5. Cymbidium has a stronger cold tolerance than other orchids. Cymbidium grows in high mountains where the altitude is higher than that of other orchids and the temperature is lower than that of other orchids, generally about 1000 meters. It is often tempered by low temperatures below 0 degrees Celsius and has an instinctive cold resistance function. After going down the mountain, it inherits the genetic factors of cold resistance to a certain extent, and the cold resistance is much stronger than other orchid species. therefore, it can enter the room later in winter, and the general temperature is below zero degrees to prevent freezing. Spring out of the room, can be earlier than its orchid, above zero can be out of the room. Give it cold-resistant training. According to the cold resistance of Cymbidium, the slow period of leaf bud is the stage of flower primordium formation, and the temperature is no higher than 23 ℃. The growth dormancy period in early spring in winter is the period of flower bud growth and development. When the temperature is no higher than 15 ℃ and the temperature in the orchid room reaches more than 15 degrees, it is necessary to open all the doors and windows of the orchid room to facilitate ventilation and cooling to meet the temperature necessary for its reproductive growth. In addition, I once made a cold resistance test. A pot of ordinary cymbidium was placed outside the south balcony all winter (avoiding the severe northwest wind in winter). The lowest outdoor temperature is about minus 50, sprouting and growing as usual in spring. It didn't freeze to death (the old leaves are a little withered), which shows its strong cold tolerance (the climate of Jiangsu and Zhejiang). This is an experiment and it is better to enter the house in the depths of winter. 6. Huilan has the habit of being full of joy. As the small bulbs store less nutrients, it is appropriate for more plants to grow in clusters, so when turning over the pot to divide and replant, the pot plants must not be less than 3 seedlings, and it is better to have more. It is not suitable to cultivate a single plant, the cultivation of a single plant is easy to fall seedlings, even if they survive, the new seedlings are also weak seedlings. Practice has proved that my single plant has been bred in a pot. Although I have survived, I will have one seedling in the first year and two seedlings in the second year. The new leaves are only more than 10 centimeters high. I don't know when they will be able to rejuvenate and blossom. 7. Cymbidium has the habit of requiring higher ventilation. Since the original cymbidium is mostly on the hillside at a higher altitude, the mountain wind is blowing wildly, which has developed the habit of requiring higher ventilation than other orchids. Therefore, planting Huilan should pay more attention to ventilation than other orchids. Put indoor cultivation, can install electric fans, exhaust fans to help exhaust ventilation, conditions, it is best to put on the shelf outside the window or in the garden to cultivate. The ancients said: ventilation is the first essence of raising orchids. This is more important for Huilan. 8. Cymbidium has the habit of relatively low air humidity, drought tolerance and waterlogging resistance. Cymbidium grows in places with high altitude, less Rain Water and strong sunshine, and the air humidity is very low. in order to adapt to the drier environment of the native place, Huilan has more vascular bundles, dense leaves, less leathery flesh, relatively low air humidity, drought tolerance and strong waterlogging resistance. Therefore, the moisture content of potted Cymbidium is better than that of wet and dry (slightly drier than Chunlan). The environmental humidity is lower than that of other orchids, and the air humidity is not less than 40%. 9. Others. ① due to the strong and thick leaves of Cymbidium, dense fiber bundles, fertilization should focus on the application of phosphorus and potassium fertilizer; ② temperature difference between day and night should be large, strive to keep the temperature difference between day and night at about 10 degrees, conducive to the storage of nutrients, timely budding; ③ orchid pots should be placed in a stable position, do not move from east to west; ④ plants should be thicker than other orchid species, (generally speaking: the root is coarse, the root is fine), which is of great benefit to the strong seedlings of Cymbidium. To sum up, Cymbidium has the characteristics of light, dark, ventilation, blocking, loosening, fertilization, concentration, dryness, humidity and temperature difference. According to these characteristics, it is not difficult to cultivate Cymbidium according to these habits. There is a jingle: "planting orchids for a few minutes, raising orchids for many years, as long as you understand habits, the more successful." It is hoped that Orchid Friends will find out their habits and increase their cultivation experience in the process of cultivating Orchid, which is bound to be successful. Finally, I would like to remind you that for the introduced mature grass with flowers, with the long-term domestication after going down the mountain and the change of the environment, the habits of Cymbidium will also change and adapt to the microclimate of the orchid garden and family. The above is mainly for the downhill cymbidium, the cymbidium must be based on their own reality, do not apply mechanically, only for reference.
