Last Updated: 2024/11/05, Q: What are the requirements for water? How to manage water properly? A: As a plant, the main component of Gastrodia elata is water, and the weight of water accounts for about 80% of fresh hemp. This is the foundation. However, since Gastrodia elata has no roots, it cannot absorb water from the soil. It can only rely on Armillaria mellea to supply necessary water. This is the main characteristic of Gastrodia elata. The growth of Armillaria mellea also requires corresponding water supply, and it is determined by the symbiotic relationship between the two. They must live together in the same environment.

Q: what are the moisture requirements of Gastrodia elata? How to carry out proper water management?

A: as a plant, the main component of Gastrodia elata is water, which accounts for about 80% of the weight of fresh Gastrodia elata, which is the foundation. However, because Gastrodia elata has no roots and cannot absorb water from the soil, it can only rely on Armillaria mellea to supply the necessary water. This is the main feature of Gastrodia elata. The growth of Armillaria mellea also needs corresponding water supply, and, determined by the symbiotic relationship between the two, they must live together in the same environmental conditions, therefore, the appropriate water content of sandy soil has become an indispensable important condition. Under general natural conditions, through shading, watering and other management measures, the moisture content of sand cover is kept at about 10%, and the humidity reaches 70% to 80%, which can meet the growth needs of Gastrodia elata and Armillaria mellea. The specific water management operation is to determine the specific water consumption according to the temperature, wind force or degree of dryness. For example, under the climatic conditions in Shandong, it is not necessary to carry out heavy irrigation before April because of small evaporation, slow growth rate of Armillaria mellea and Gastrodia elata, and small water demand. However, if in May, with the advent of hot and dry wind, the increase of temperature will increase the amount of evaporation, then water management should be strengthened. After July, when the ground temperature reaches more than 28 ℃, Gastrodia elata is about to enter the state of summer dormancy. If there is a flood, on the one hand, appropriate moisture can effectively lower the temperature, so that Gastrodia elata can continue to maintain its growth trend, on the other hand, if the moisture is too large, it is just to meet the characteristics of Armillaria mellea liking flood, it is easy to cause "nutritional reflux", resulting in "bacteria sucking hemp", resulting in "rotten nest" phenomenon. In short, according to the specific temperature and Gastrodia elata growth law, the implementation of specific water management, do not follow others, copy.
