Planting Gastrodia elata according to different temperature conditions
The main condition needed for Gastrodia elata and Armillaria mellea is temperature. It can grow and develop normally under the condition of 2-28 ℃. How to control this condition is the most important factor in the success of Gastrodia elata production. Temperatures in various parts of the country can be divided into three types:
(1) Heilongjiang, Jilin, Liaoning, Inner Mongolia, Qinghai, *. These areas must not cause the seedlings to freeze in winter, and do not need to consider the effect of high temperature on the growth of Gastrodia elata in summer. the best plan is to plant Gastrodia elata indoors and heat it up slightly in winter so that it is appropriate not to freeze indoors. Outdoor planting Gastrodia elata is mainly covered with cold protection, or spring and autumn harvest.
(2) Shandong, Hebei, Shanxi, Shaanxi, Hubei, Anhui, Jiangsu and Henan, these areas should not only prevent frost, but also prevent heat. The best plan is to plant them in well-ventilated rooms and spray water to cool down in summer. The factory produces available air conditioners or ice cubes to cool down; keep it indoors for 2 ℃ in winter.
(3) Hunan, Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi, Sichuan and other places, mainly consider how to cool down, should make full use of air-raid shelters, caves, high mountain forests, factory production of available air conditioners. In short, try to keep the indoor temperature no more than 28 ℃ in summer and no ice in winter.

What is the effect of management level on the yield of Gastrodia elata
Strengthening management is an important measure to obtain high yield of Gastrodia elata. Mainly turn off the temperature and humidity. During the growth of Gastrodia elata, the temperature is controlled at 20-25 ℃, not more than 25 ℃. The optimum humidity for Gastrodia elata growth is 65%, not more than 70%. In the irrigated water, it is best to add some grain and vitamin B1, that is, to irrigate nutritious water. In addition, ventilation and shading are needed. To prevent and cure all kinds of miscellaneous bacteria and mice, mole cricket and other harm to Gastrodia elata. In short, it is required to promote the word "early" in flax planting, and the fungus stick requires the word "good", Wen.

Feigu artificial Gastrodia elata
Gastrodia elata was originally wild, and it was mostly collected. Through scientific experiments, the cultivation of Gastrodia elata by sexual reproduction has been successful, its planting technology and practical experience have mature theory, and the time is ripe for introduction and planting. On the basis of this, the Feigu Village Committee of Delu Township of Xuanwei City, based on the reality in the adjustment of industrial structure, and on the basis of full investigation of the market, carefully analyzed the local natural conditions such as soil structure, altitude, temperature difference between day and night, climatic environment and so on. it is considered that the conditions for planting Gastrodia elata in the local area are ripe and can be further promoted after the trial planting of some village committees.
