Field management technology of Gastrodia elata

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

1. Humidity management

Gastrodia elata has the characteristics of like yin, dampness and fear of waterlogging. The planting area should maintain a certain degree of humidity, which should be kept at about 50% to 60%. The peak growth period of Gastrodia elata is from May to September every year, so the demand for water is even greater, so it is necessary to water scientifically to maintain humidity. If the amount of water is reduced by pressure in winter, the humidity in the field only needs to be about 35% to 40%. In the case of continuous rainfall for many days, the excess water should be discharged in time and a good ditch should be set up to avoid stagnant water in the field.

2. Temperature management

Gastrodia elata also has the characteristics of being cool and afraid of high temperature, but this does not mean that it is particularly resistant to low temperature, so we should be more careful in temperature management. In general, Gastrodia elata grows fastest at a temperature of 20 to 25, and the temperature suitable for the growth of Gastrodia elata is about 18 to 28 degrees. At the same time, it can withstand a low temperature of about five degrees below zero, but when it is below six degrees below zero, it needs to be covered with plastic film to keep warm. When the temperature rises to about fifteen degrees, it is necessary to uncover the plastic film.

3. Nourishment disinfection

The nutrients planted with Gastrodia elata need to be sterilized. Generally speaking, the nutrients of Gastrodia elata need to be accumulated and fermented before they can be released, but in this process, a lot of bacteria may be produced. If the nutrients are not sterilized, they will be released directly. It is very likely to affect the growth of Gastrodia elata plants and cause diseases.

4. Pest control

The diseases of Gastrodia elata are mildew, rot and sunburn. Mildew is mainly caused by the lack of disinfection of nutrients and the management in the later stage, which causes other miscellaneous bacteria to infect the plant and produce mildew. We can use carbendazim for control. Rot is mainly caused by high temperature and humidity, which can be controlled by adjusting moisture and temperature in the field. White burn disease is a physiological disease, which needs to be controlled by building shade. Finally, Gastrodia elata has many insect pests, such as mole cricket, grubs, ants and so on, which can be controlled by dimethoate.

The above is the whole content of the field management of Gastrodia elata cultivation in time. I believe you have a certain understanding of the field management of Gastrodia elata. This is the end of the editor's sharing today! I hope I can help you to grow Gastrodia elata.
