What effect does high summer temperature have on Gastrodia elata?
In low-altitude hilly areas, under high temperatures of 32-34°C, lasting 10 days (240 hours) has little effect on Gastrodia elata and can still produce arrow tubers, while when the high temperature lasts 15 days (360 hours), the yield of Gastrodia elata will be affected. Therefore, the baseline of Gastrodia elata's tolerance to high temperature is relatively high. Summering of Gastrodia elata is not only related to the value of the absolute high temperature, but depends even more on the duration of the high temperature. Because under outdoor natural conditions there are monthly temperature differences and daily differences from day-night changes, and in addition artificial cultivation adopts shading and other regulating measures

How to regulate temperature when cultivating Gastrodia elata in plains and low mountain areas
The biggest difficulty in cultivating Gastrodia elata in plains and low mountain areas is controlling high temperatures and regulating temperature differences. (1) For indoor cultivation, cold water can be sprayed in the walkways and space, but water must not accumulate at the bottom layer of the Gastrodia elata. At the same time, open the opposing windows facing north and south for ventilation, or use an electric fan to cool down while opening the windows, so that air convection is achieved and the cooling goal is reached. When the temperature is low, close the doors and windows, and make the temperature difference as small as possible. (2) For outdoor cultivation, more broadleaf trees and green vine plants can be planted on the cultivation site, so that the cultivation site is cool and moist.

Cultivation Methods for Gastrodia elata Under 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 or fails. 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 do not freeze in winter, and in summer there is no need to consider the effect of high temperatures on the growth of Gastrodia elata. The best plan is: plant Gastrodia elata indoors, with slight heating in winter, so that the indoor space does not freeze.

What temperature requirements does Gastrodia elata have for cultivation?
Temperature is an important factor affecting the growth and development of Gastrodia elata, and besides the influence of seasons, temperature is also affected by latitude and altitude. Generally speaking, for every 10° increase in latitude, the average temperature drops by 0.5°C, and for every 1000 m increase in altitude, the climate drops by about 6.5°C. Therefore, wild Gastrodia elata mostly grows in mountainous areas and has an ecological preference for cool, humid conditions. During artificial cultivation, we found that: when the temperature of the planting layer rises above 10°C, the terminal buds of Gastrodia elata begin to sprout and start to grow; when the temperature rises above 20°C, it grows rapid

What temperature conditions does Gastrodia elata need to grow?
Q: What kind of temperature conditions does Gastrodia elata need to grow? What are the extreme temperatures? A: This question seems simple, but is actually rather complex. Based on the actual situation in our province, we might as well give a brief explanation from the following two aspects. First, the original intention of most farmer friends in asking this question should refer to the adaptability of Gastrodia elata tubers to temperature in asexual cultivation. As a plant, Gastrodia elata has no roots and no leaves, and its ability to adapt to and regulate temperature is weak, which is its growth disadvantage. However, since

What effect does low winter temperature have on Gastrodia elata
The tubers of Gastrodia elata are buried underground and overwinter in a dormant state; the stable low temperature they can tolerate is 0-5°C. However, if winter temperatures fluctuate frequently, with large swings in temperature difference, sudden warmth followed by sudden cold, Gastrodia elata is prone to cold damage. Therefore, special attention should be paid to cold protection and heat preservation for overwintering Gastrodia elata, especially for box-cultivated Gastrodia elata, which should be covered even more carefully to preserve warmth and prevent cold damage. But Gastrodia elata has a certain low-temperature cycle and requires an appropriate stable low temperature in winter, otherwise its sprouting will be adversely affected.

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
