How to Grow Gastrodia elata According to Different Temperature Conditions

 The conditions required by Gastrodia elata and Armillaria are mainly temperature. It can grow and develop normally under conditions of 2-28°C. How to control this condition is the most important factor in whether Gastrodia elata production succeeds. Temperatures across the country can be broadly divided into three major types:

(1) Heilongjiang, Jilin, Liaoning, Inner Mongolia, Qinghai, Xinjiang. In these areas, it must be ensured that the seedlings do not freeze in winter, and there is no need to consider the effect of high temperatures on Gastrodia elata growth in summer. The best plan is: plant Gastrodia elata indoors, with slight heating in winter, so that the indoor temperature does not freeze. Outdoor Gastrodia elata cultivation mainly involves adding cold protection materials, or planting in spring and harvesting in autumn. (2) Shandong, Hebei, Shanxi, Shaanxi, Hubei, Anhui, Jiangsu and Henan. In these areas, in addition to preventing freezing, heat protection is also needed. The best plan is: plant in well-ventilated indoors, and spray water to cool down in summer. Factories can use air conditioning or ice cubes to cool down; in winter, keeping the indoor temperature at 2°C is sufficient. (3) Hunan, Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi, Sichuan and other places mainly need to consider how to cool down, and should make full use of air-raid shelters, mountain caves, and high mountain dense forests. For factory production, air conditioning can be used. In short, try to ensure that the indoor temperature does not exceed 28°C in summer and does not freeze in winter.
