Enlightenment from the Growth Environment of Wild Cymbidium

1. The key to good cultivation of Cymbidium is sufficient light, high humidity, large temperature difference and good ventilation. (because modern orchid cultivation, plant materials, water and fertilizer are no longer the main problem) how to combine the three elements organically and reasonably is the success. Although Huilan requires an environment with sufficient light, it is not suitable for strong direct light in summer. Sufficient light, suitable humidity, strong plant growth, straight leaves and rich luster; lack of light, the plant is weak, the leaves are slender, sagging, no luster, and the number of flowers decreases. In general, the first layer of light transmittance 50% shading net is better in summer. Humidity is kept at about 70-85%, windows are opened for natural ventilation at night to meet the needs of temperature differences, and various methods are taken to cool down in summer, such as air conditioners, fans, water curtains, walls and floors, and so on. Control the temperature below 31 degrees, so that the leaves of Cymbidium are not spotted, not scorched, green and beautiful, and appear more atmospheric and fluffy than Chunlan.

2. The problem of seedling emergence rate: for example, if the female parent is strong, if you want to send more seedlings, you need to plant them shallowly, because they are planted deeply, such as living in a wet state for a long time. The reserve buds of bluegrass are necrotic by excessive dampness and moisture, so it is difficult for many seedlings to grow new buds. Here I would like to dedicate to you what I have learned over the years. In order to make the seedlings of Cymbidium grow in full light from November to March, it is best to cut open the plant so that the false bulbs are slightly exposed to the basin, and ensure that sufficient light is given to activate this driving force. At the same time, another key point is to deduct water in March and let the basin soil dry several times so as to force new buds, which is rarely mentioned in the Lan Shu. We may all know the fact that withholding water in July can force flower buds, but in fact, their reasons are the same. Over the past few years, the seedling rate of my Cymbidium has been more than 100%, and this year is a new record for two seedlings, four false bulbs and seven seedlings. In addition, if the orchid is not very healthy or is still in the conservation stage, it is not easy to use the method of deep planting, otherwise the core is perishable. If the number of seedlings is also large but need to be rejuvenated, the cymbidium can be slightly planted deeper, and the deep planting in large pots has a good effect, which is easy to produce strong seedlings, which is conducive to the rejuvenation of orchids, but the seedling rate will be lower than that of shallow species in large pots. Of course, the premise of large pot deep planting is that orchid farmers should be able to make the correct nursing action of watering buckle suitable for the application of large basin deep planting, otherwise it will also produce unfavorable conditions.
