What conditions are needed for growing Bletilla striata? A detailed explanation of environmental requirements
Bletilla striata has been a very popular medicinal herb growing project in recent years, and at the same time a highly controversial one. Many people say growing Bletilla striata makes money, while many others say it loses money and is a growing scam. In fact, whether growing Bletilla striata is profitable must be analyzed from all aspects and cannot be discussed one-sidedly. So today let us first understand the growing conditions for Bletilla striata, and take a look together.
1. Soil requirements
The planting site for Bletilla striata should be chosen as sandy loam with loose texture, sufficient fertility, and rich in organic matter and humus, or clayey soil. Next, the drainage conditions of the planting site must be good, and it is best to choose a shady slope for planting, among which the soil pH should be moderate, ideally between 6.5 and 7.5. Also, attention must be paid to crop rotation; continuous cropping is not allowed. At the same time, note that heavy clay and sandy soil are both unsuitable for growing Bletilla striata, because their permeability is too poor.
2. Light requirements
Bletilla striata prefers shade, has strong shade tolerance, and fears strong light, so light conditions are also an important factor in growing Bletilla striata, which is also why the planting site should be chosen on a shady slope. If the light near the Bletilla striata planting site is intense, then it is necessary to build a shade shed for shading, because too strong light will slow down the growth rate of Bletilla striata, very likely cause it to stop growing, and finally lead to yellowing and falling of leaves, or even death. But reasonable light is beneficial for promoting photosynthesis in Bletilla striata, thereby forming flower buds, promoting flowering and fruiting, and ultimately achieving the goal of increasing yield.
3. Temperature requirements
Bletilla striata is suited to growing in a warm environment, but in most regions of our country the climate changes considerably across the four seasons, and the temperature difference between day and night is also relatively large, so to allow Bletilla striata to grow normally, the temperature needs to be reasonably adjusted. This is especially true in summer and winter. In summer, high temperatures and low humidity will seriously affect the growth of Bletilla striata, while in winter, low temperatures, together with frost and snowfall, will cause Bletilla striata to stop growing. So in summer we need to carry out cooling measures, and in winter we need to carry out insulation measures. Ensure that the temperature at the Bletilla striata planting site does not exceed 30 degrees at the highest and does not fall below 10 degrees at the lowest.
4. Water and fertilizer requirements
Bletilla striata has a relatively large demand for water and fertilizer, but its requirements for fertilizer and water are also quite strict, and fertilizer cannot be applied randomly. So what we need to note is that during the growing process, nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer must not be applied one-sidedly, and concentrated fertilizer must not be applied randomly. When fertilizing, we should follow the principle of frequent application of thin fertilizer, and ensure balanced nutrition, using each fertilizer type in a scientific ratio. Also, attention must be paid to the principle of watering, which is usually to alternate between dry and wet, drying thoroughly when dry, not watering when not dry, and watering thoroughly when watering, so as to promote the growth of Bletilla striata. Finally, after fertilizing, attention should be paid to watering to dilute the concentration, while also promoting the absorption of nutrients, so as to avoid causing fertilizer burn to the seedlings.
In fact, in the process of growing Bletilla striata, what we most need to pay attention to is the growing environment and growing techniques. If both of these reach the standards for growing Bletilla striata, then there will not be much trouble in growing Bletilla striata. The above points are what the editor wants to share with everyone today. Everyone must pay great attention during the growing process, and I also hope it can help all friends in need.
