The unique skill of Huilan cultivation

The cultivation of Huilan seems to have reached a consensus on the method of burying large basins and deep burial to control water. The method of deep burial and water control in a large basin: first, plant Cymbidium in a large basin, because the root system of Cymbidium is more developed than that of Chunlan, and the small basin is not conducive to root growth; second, the false bulb should be buried in the soil 2 or 3 centimeters when potting, and the plant material should not be exposed; third, Cymbidium is more drought-resistant and cannot be watered too frequently. Under the same dry and wet conditions, the overall growth of Cymbidium will improve a day or two later than Chunlan. At the same time, pay attention to moisturizing, the air humidity is higher, the basin is slightly drier, and the grass is easy to pull up. I would like to express my views on the observation of wild cymbidium and my usual conservation experience over the past few years.

The main results are as follows: 1. The growth of Cymbidium in nature makes us think: the native place of Cymbidium is higher than that of Chunlan, it is more cold-resistant, dry-resistant and likes to grow in sunny and ventilated places on hills and hilltops. Because Cymbidium grows at high altitude, strong wind and small pseudobulbs, in order to adapt to the living environment, Cymbidium: (1) develop by the depth of the stout orchid root. If the orchid root with a deep layer of rotten leaves will be deeply rooted in the soil, because of the wind, the false bulbs will naturally be buried deep in it. Cymbidium grows particularly tall in this environment, and you will see Cymbidium which grows more than 1 meter tall on the mountain. (2) rely on the developed group root hand in hand and heart-to-heart spirit of unity and cooperation to absorb the nutrition of the earth. Most of these cymbidium grow in the shallow soil layer on the cliff, characterized by a small stature, but a large number of seedlings. Sometimes you will see a cluster of more than 70 seedlings of the original population, very spectacular. All you have to do is sled with a stick and all will be unearthed. Seeing such roots with only a little rotten leaf soil in them will give you a lot of inspiration for the cultivation of Cymbidium.

2. The thinking brought to us by the changes of cultivation environment and climate: in ancient times, most of them were literati and aristocrats, who all had a good orchid environment in the hall and courtyard, unlike most of us now growing orchids on balconies or roofs. Fundamental changes have taken place in the cultivation environment. The weather this year is rare in a century, with no continuous spring rain, no rain in the plum rainy season, and persistent high temperatures in summer. In such an environment, planting Cymbidium pseudobulbs deep in the soil is as uncomfortable as wearing a scarf in summer. This year, local orchids have also suffered from the deep planting of Cymbidium. Many solitary products of Cymbidium have died of stem rot. Of course, there are many other causes of death, such as plant material, water, fertilizer and so on, but according to my investigation, the vast majority of people who died was Huilan. This has to arouse our vigilance. At the same time, as we all know, the false bulb is the reservoir of orchid nourishment and water, which plays an important role as a connecting link between the preceding and the following. Soil decomposition, root absorption, after photosynthesis, processing into all kinds of organic matter, transported to pseudo-bulb storage, and then continuously supply the growth of new roots and seedlings. This complex process of processing, manufacturing, and supply all depends on the power of light, so from this principle, Cymbidium can not be deeply planted, and pseudobulbs should be slightly exposed on the surface to ensure that sufficient light is given to activate this driving force.

The enlightenment from the growing 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 sufficient light, it is not suitable for strong direct light in summer, and the best light intensity is 15000 to 25000 lux. Sufficient light, strong plant growth, straight leaves and rich luster; lack of light, the plant weak, slender leaves, sagging, no luster, the number of flowers decreased. In general, the first layer of light transmittance 50% shading net is better in summer. The humidity is maintained at about 70-85%, and the windows are naturally ventilated at night to meet the needs of the temperature difference. In summer, various methods are taken to cool down the temperature to keep 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 compared with 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. I would like to pass on to you the experience I have learned over the years. In addition to strengthening photosynthesis, another key point for Cymbidium seedlings is to withhold water in March so that the basin soil can dry out so that new buds can be forced. This is rarely mentioned in the Lan Shu. We may all know the fact that buckle water can produce more flower buds in July, 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 small 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.
