Self-propagation and autotrophic management techniques of snakes
The following points should be paid attention to in the self-propagation and autotrophy technology of snakes: First, seed selection: Healthy and plump female snakes should be selected as seed snakes every spring. No matter poisonous snakes or non-poisonous snakes, they generally lay eggs from late June to July. The female snakes should be fed nutritious and calcium-rich food before and after laying eggs, so as to make them full and drink as much as possible. The female snake does not need to consider whether mating, female snake mating once can lay five years of fertilized eggs. 2. incubation: in order to prevent the snake eggs from drying up and sinking, the produced snake eggs should be put into the incubation tank in time for artificial incubation.

Cultivation of Gastrodia elata seed material
Gastrodia elata can not be autotrophic and must rely on Armillaria mellea symbiosis with it in order to get nutrition and reproduction and growth. Parasitic Armillaria mellea can grow on about 200 tree species, especially in broad-leaved forests. Armillaria mellea is commonly found in cut trees, bamboo or burned trees, roots of bamboo, and dead trees that fall in the forest. Armillaria mellea can only grow vigorously under certain humid conditions, the soil water content is not less than 45%-50%, and the air relative humidity is 75%-80%. Armillaria mellea can also be cultivated artificially, which must be cultivated first.

Why does Gastrodia elata have soft rotten nest? How to avoid the occurrence of this disease
Soft rot nest disease of Gastrodia elata is one of the reasons for its low and unstable yield in cultivation. Soft rot occurred in rice hemp, white hemp and arrow hemp, the tuber bark was yellow, the central tissue was rotten, and the section of the tuber exudated a stinky white serous liquid. Armillaria mellea is lush and dense in the burrow of Gastrodia elata and in the tuber. Gastrodia elata grows on Armillaria mellea. Why do soft rot nests and tubers fill with Armillaria mellea mycelium? In order to explore this problem, we should start with the nutritional ecology of Gastrodia elata. Gastrodia elata has no roots and no green leaves, and its autotrophic organs degenerate, which depends on Armillaria mellea.

Control of diseases and insect pests in Tianma cultivation period
Gastrodia elata is a commonly used Chinese herbal medicine. It is a special seed plant, no roots, no green leaves, can not autotrophy, must rely on the symbiosis of dense ring bacteria to obtain nutrition and reproduction growth. Therefore, the cultivation of Gastrodia elata is different from planting green plants, and it must be done according to its growth law. One is the cultivation of dense ring fungus material, the other is the selection and cultivation of gastrodia elata seed hemp, and the third is the symbiotic cultivation of gastrodia elata and dense ring fungus. In these three production links, there are opportunities for contamination of miscellaneous bacteria, and each step is not good.
