The latest course on technical methods of field management of Gastrodia elata

Gastrodia elata is divided into spring hemp and winter hemp, spring hemp quality and winter hemp is good. Gastrodia elata is mainly a kind of traditional Chinese medicine used to treat vertigo, black eyes, head wind, pain, limb numbness, hemiplegia, infantile convulsion and wind. At present, it is mainly planted in Jilin, Hubei, Guizhou, Yunnan and other places in China. So how do you manage the planting process? Let's study together today.

1. Humidity management

Gastrodia elata has the characteristics of yin, dampness and waterlogging. The planting area should maintain a certain humidity, generally about 50 to 60 percent. Gastrodia elata growth period is in the annual May to September this period of time, then the demand for water is also greater, then scientific watering, to maintain humidity. In winter, the amount of water was reduced, and the humidity in the field only needed to be about 35 to 40 percent. In the case of continuous rainfall for many days, excess water should be drained in time and ditches should be built to avoid ponding in the field.

2. Temperature management

Gastrodia elata also has the characteristics of being cool and afraid of high temperatures, but this does not mean that it is particularly resistant to low temperatures, so we must be more careful in temperature management. Generally, Gastrodia elata grows fastest at a temperature of 20 to 25 degrees Celsius, and the temperature suitable for Gastrodia elata growth is generally around 18 to 28 degrees Celsius. At the same time, it can withstand a low temperature environment of about minus five degrees Celsius, but when it is lower than minus six degrees Celsius, it needs to be covered with plastic film for insulation. When the temperature rises to about fifteen degrees Celsius, it needs to be uncovered.

3. Nutrient disinfection

Gastrodia elata planting nutrients need to be disinfected. The nutrients of Gastrodia elata generally need to be accumulated and fermented before they can be released. However, in this process, a lot of bacteria and the like may be produced. If the nutrients are released directly without disinfection and sterilization, it is likely to affect the growth of Gastrodia elata plants and cause diseases.

4. Pest control

Gastrodia elata diseases have mold disease, rot disease, sunburn disease, mold disease is mainly nutrients do not disinfect and late management in place, caused by other miscellaneous bacteria, infected plants, resulting in mold disease. We can use carbendazim for control. Rot disease is mainly caused by high temperature and humidity, and can be controlled by adjusting the moisture and temperature in the field. Whiteburn is a physiological disease, which needs to be controlled by setting up shade shed. Finally, Tianma still has a lot of pests, such as mole cricket, grubs, ants, etc., you can use dimethoate control.

The above is the field management of Tianma planting timely all the content, I believe we also have a certain understanding of Tianma field management. That's the end of today's sharing! Hope to help you grow gastrodia elata friends.
