1. Select suitable tree species to cultivate Armillaria mellea. Gastrodia elata can be cultivated in FAGACEAE, betulaceae, Rosaceae, Leguminosae and other tree species without aromatic oil. Among them, oak, birch, watermelon, cherry, acacia and Toona sinensis are better. Armillaria mellea should be cultivated 2 ~ 3 months in advance in winter, and a fixed Armillaria bed should be built; Armillaria materials for spring planting should be built in September ~ 65438+1October. Cutting time of trees: during the winter solstice, after the trees are cut and broken, they will be cultivated in the cellar for 20-30 days, and can be cultivated in the cellar from June to September. 2. The dosage of Armillaria species and Armillaria material is 2 bottles per square meter. The amount of Armillaria mellea fungus is 6-8 coarse fungus materials per square meter (6- 12 cm in diameter and 50 cm in length) and weighs 25-30kg. There are 5 ~ 8 bacterial materials (2 ~ 5cm in diameter and 10cm in length) weighing about 6kg. 3. The characteristics of the sown Gastrodia elata variety 1 are biased towards the female parent, that is, the main characteristics are similar to those of Gastrodia elata, and the outstanding point is that the seed Gastrodia elata has poor meristematic ability. In production, the first generation of sexual hybrid hemp has the best cultivation effect, followed by the first and second generations of asexual hybrid hemp, and there is almost no separation of white and rice hemp seeds after three generations of cultivation. When sowing, put the seed hemp near the fungus material, 6 seed hemp on one fungus material, 4 in the middle of the fungus material, 1 at both ends. The dosage of seeds is about per square meter 1 kg, and the seeds of white and rice hemp are about 40 ~ 50. Both hole sowing and line sowing can be done. The cultivation depth is about 15cm. When the cultivation hole is covered with soil, it should be covered and filled with fine soil. There is no gap between the seed hemp and the soil, between the fungus material and the fungus branch and the soil. The cultivation holes are covered with deciduous broad-leaved trees, thatch, rice straw, corn stalk, etc., and the covering thickness is 2 ~ 3 cm. Then open the drain pipe. 4. Tian Tuan management

(1) Use plastic film to keep warm in winter and early spring. The temperature of the soil layer below 10 cm in the cave should be kept at 0℃ ~ 5℃. In July, August and September, it must be adjusted with plastic film or shade shed to control the temperature within 26℃.

(2) Moisture management: 12 ~ 3 months, humidity control and frost prevention, soil moisture content is 30%, just look at the water content. Increase moisture to promote growth from April to June, and the soil moisture content is 60% ~ 70%, which can be dispersed when held in your hand. From July to August, the humidity and temperature decrease, and the soil moisture content is about 60%. September-65438+10 month, water control and bacteriostasis. The soil moisture content is about 50%, and it will be slightly caked when held in your hand, and then it will be scattered when gently rubbed. 1 1 month, the soil moisture content is about 30%, and it is dry and loose. At the same time, pay attention to weeding and insect prevention during the growing season. 5. Harvesting areas below the altitude of1200m should be excavated after the first frost. When excavating, it should be carried out when the weather is clear and the soil is cool. It is forbidden to excavate in rainy days or after rainy days 1 ~ 2 days. When digging, two kinds of baskets and boxes should be prepared, one for planting marijuana and the other for commercial marijuana. Seed hemp should be sown or transported and stored in time as required, and commercial hemp should also be processed and dried in time. Gastrodia elata belongs to Armillaria species and should be sold on Taobao.
