How to plant 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. The temperature all over 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.
