How is Gastrodia elata planted according to different temperature conditions?

The conditions required by Gastrodia elata and Armillaria mellea 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, **. In these areas, it must be ensured that the seedlings are not damaged by freezing 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 it is suitable if the room does not freeze. Outdoor planting of Gastrodia elata 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 indoors with good ventilation, and in summer water can be sprayed to lower the temperature. For factory production, air conditioning or ice blocks can be used to lower the temperature; in winter, keeping the indoor temperature at 2°C is enough.

(3) Hunan, Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi, Sichuan and other places. The main consideration is how to lower the temperature. Air-raid shelters, mountain caves, and high mountain dense forests should be fully utilized. For industrial production, air conditioning can be used. In short, try to ensure that the indoor temperature does not exceed 28°C in summer, and it is best if it does not freeze in winter.
