What are the conditions for planting small white medicine? What are the conditions for planting Bletilla striata?

1, soil requirements: Bletilla striata should be planted in sandy loam with loose soil, sufficient fertility and rich organic matter and humus, or in cohesive soil. Secondly, the drainage conditions of the planting site need to be good, and it is best to choose shady slope planting, in which the PH value of the soil needs to be moderate, and the pH value is preferably between 6.5 and 7.5. There is also the need to pay attention to crop rotation and not to repeat crops; At the same time, it should be noted that heavy clay and sandy soil are basically not suitable for planting bletilla striata because the permeability of soil is too poor.

2. Lighting requirements: Bletilla striata likes shade, has strong tolerance to shade and is afraid of strong light, so lighting conditions are also a crucial factor for planting Bletilla striata, which is why planting sites need to be selected on shady slopes. If the light near the planting area of Bletilla striata is strong, then a shade shed must be built to shade the sun. Because the light is too strong, it will slow down the growth rate of Bletilla striata, which is likely to affect the growth of Bletilla striata, and finally the leaves will wither, fall and even die. However, reasonable light is beneficial to promote the photosynthesis of Bletilla striata, which will form flower buds, promote flowering and fruiting, and finally achieve the goal of increasing production.

3. Requirements of _ _ _ degree: Bletilla striata is suitable for growing in a warm environment, but in most parts of China, the climate changes greatly in four seasons, and the temperature difference between day and night is also quite large. For the normal growth of Bletilla striata, it is necessary to adjust _ _ degree appropriately. Especially in hot days and winter, high temperature and low humidity will seriously affect the growth of Bletilla striata, while low temperature in winter, frost weather and snowfall will affect the growth of Bletilla striata. Then it is necessary to do a good job of cooling in hot weather and heat preservation in winter. Ensure that the highest temperature in the planting area of Bletilla striata does not exceed 30 degrees, and the lowest temperature is not lower than 10 degrees.

4. Water and fertilizer requirements: Bletilla striata has a great demand for water and fertilizer, but the requirements for fertilizer and water are also quite strict, and indiscriminate fertilization is not allowed. It should be noted, then, that nitrogen fertilizer, potassium fertilizer and phosphate fertilizer should not be applied in a partial way, and concentrated fertilizer should not be applied indiscriminately. When applying fertilizer, it is necessary to follow the principle of applying thin fertilizer frequently to ensure balanced nutrition, and all kinds of fertilizers should be used in a scientific proportion. There is also the need to pay attention to the principle of watering. Under normal circumstances, it is the principle of both wet and dry, and it needs to be dried thoroughly. If you don't do it, you can water it thoroughly. Only in this way can you promote the growth of Bletilla striata. Finally, attention should be paid to the dilution concentration of water after fertilization, which can promote the absorption of nutrients and avoid burning seedlings.
