Detailed Explanation of the Key Technical Points of Gastrodia Field Management

Gastrodia is divided into spring gastrodia and winter gastrodia, and the quality of spring gastrodia is not as good as that of winter gastrodia. Gastrodia is mainly a kind of Chinese medicinal material used to treat conditions such as dizziness and blackouts, head wind, pain, numbness of the limbs, hemiplegia, and infantile convulsions with wind. At present, it is mainly cultivated in Jilin, Hubei, Guizhou, Yunnan and other places in China. So how should management be carried out during the gastrodia planting process? Today let us learn about it together.

1. Humidity management

Gastrodia has the characteristics of preferring shade, preferring moisture, and fearing waterlogging. The planting site should maintain a certain humidity, generally kept at around 50% to 60%. The vigorous growth period of gastrodia is from May to September each year, so the demand for water is also greater, so watering should be carried out scientifically to maintain humidity. In winter, the amount of water should be reduced, and the field humidity only needs to be around 35% to 40%. In the case of continuous rainfall for many days, excess water should be drained in time and drainage ditches should be made well to avoid water accumulation in the field.

2. Temperature management

Gastrodia also has the characteristics of preferring coolness and fearing high temperatures, but this does not mean that it is particularly tolerant of low temperatures, so we need to be relatively careful in temperature management. Generally, gastrodia grows fastest at a temperature of 20 to 25, and the temperature suitable for gastrodia growth is generally around 18 to 28 degrees. At the same time, it can withstand a low-temperature environment of around minus 5 degrees, but when it is below minus 6 degrees, plastic film needs to be covered for insulation, and when the temperature rises back to around 15 degrees, the plastic film needs to be uncovered.

3. Nutrient disinfection

The nutrients used for gastrodia planting need to be disinfected. The nutrients for gastrodia generally need to be piled up and fermented before they can be applied, but during this process, many bacteria and the like may be produced. If the nutrients are applied directly without disinfection and sterilization, it is very likely to affect the growth of gastrodia plants and cause diseases.

4. Pest and disease control

The diseases of gastrodia include mold disease, rot disease, and sunscald disease. Mold disease is mainly caused by nutrients not being disinfected and later management not being handled properly, which leads to other miscellaneous fungi infecting the plants and producing mold disease. We can use carbendazim for control. Rot disease is mainly caused by high temperature and high humidity, and can be controlled by regulating the moisture and temperature in the field. Sunscald disease is a physiological disease and needs to be controlled by building shade sheds. Finally, gastrodia also has many insect pests, such as mole crickets, white grubs, ants and so on, which can be controlled with dimethoate.

The above is all the content on timely field management for gastrodia planting. I believe everyone has gained a certain understanding of gastrodia field management. That is the end of today's sharing by the editor! I hope it can help all friends who grow gastrodia.
