The latest field management points of Bletilla striata

Bletilla striata is a kind of traditional Chinese medicine, which is mainly used in plant tuber. Bletilla striata has the functions of astringent hemostasis, detumescence and muscle production. There is a wide range of planting area in our country, but although the planting area of Bletilla striata is wide, it is not so simple to grow, so we need to have certain management skills. Many people fail to plant because of poor management. The following editor brings you the key points of field management of Bletilla striata. Let's have a look!

1. Ploughing and weeding

The plants of Bletilla striata are very small, and it is almost impossible to distinguish Bletilla striata from weeds in the later stage if the weeding work is not done well. And the nutrient absorption capacity of Bletilla striata is relatively weak, can not seize the weeds, so we must do a good job in ploughing weeds. Weeding must not be less than three times a year, and the first weeding work is needed after sowing and emergence. Then in June gradually into the summer again, this stage is not only the vigorous growth of Bletilla striata, the growth rate of weeds is also very fast, accidentally there will be grass famine. When weeding, we should pay attention to avoid injuring the root of Bletilla striata, which will further affect the growth of Bletilla striata.

2. Water management

Bletilla striata is very fond of water and is suitable to grow in a wet environment, so our water management in the planting process is very important. After sowing, it is necessary to timely watering to promote seed germination and seedling emergence to ensure that the soil is in a moist state. Then adjust the amount of water according to the growth of Bletilla striata, shorten the watering frequency in hot and dry weather, and water at least twice a day. Watering should not be flooded to avoid waterlogging of Bletilla striata and pay attention to drainage on rainy days. Stagnant water in the field may cause root rot of Bletilla striata and cause diseases and insect pests.

3. topdressing at the right time

Like the water demand of Bletilla striata, Bletilla striata has a great demand for nutrition, and the number of topdressing should not be less than twice a year. Mid-tillage can improve soil permeability, enhance soil fertilizer absorption and promote the growth of Bletilla striata. Each topdressing can be carried out with ploughing and weeding, the first time the fertilizer is mainly manure, and then an appropriate amount of ammonium sulfate is added. The second time is based on peracid phosphorus and calcium, mixed with farm manure, and the third time is mature farm manure. Topdressing should be based on a small amount of topdressing, which should not only meet the nutrition needed for the growth of Bletilla striata, but also prevent the occurrence of fertilizer damage.

4. Control lighting

In the growth process of Bletilla striata, the light must be adjusted well, and the demand for light is relatively small in the early stage of growth. At least 70% shading is needed in the first week of seedling transplanting, and then it can be adjusted to about half. If it is not shaded in time in summer, the growth rate of Bletilla striata will be very slow, even stop growing, and the leaves will be burned, resulting in yellowing and falling leaves. In addition, the three seasons with lower temperature should have proper direct light to promote the photosynthesis of Bletilla striata and increase the accumulation of photosynthetic matter in the plant.

In winter, because the temperature is too low, we also have to do a good job of overwintering and properly cover the plastic film, but we need to uncover it once in two days or so to promote ventilation and then cover it. In addition, we also need to do a good job in the prevention and control of diseases and insect pests to avoid threats to the growth of Bletilla striata. That's all for today's introduction.
