What kind of Gastrodia elata tuber should be selected for planting
No damage, no diseases and insect pests, no deformity of Gastrodia elata tuber is the best cultivation. However, when the seed is scarce, the tuber is not seriously damaged, it can also be planted and cultivated after treatment. The treatment method is: first cut off the damaged part with a knife or bamboo, the knife edge is insolated to the extent that it does not run pulp, and then plant it, which can grow as usual.
After a year of cultivation, it can be turned into a large arrow hemp. Arrow hemp to do asexual reproduction of seed cultivation must break the top of the arrow hemp "parrot mouth"-like mixed buds, so that arrow hemp does not produce arrows (no longer stem), called "killing arrows". After killing the arrow, it should be hung to dry, so that the part of the broken bud can form a film (no longer exosmosis) before it can be cultivated, otherwise it is easy to rot. Three or five large, medium white hemp and a small amount of millet hemp can be grown one year after the arrow flax is planted.
Large white hemp can be processed into commercial hemp as medicine, but it is not cost-effective to cultivate it as a species, but some people have used the method of killing arrows to kill buds (mainly to break the top advantage). The method of killing buds is the same as that of arrow hemp, cutting out buds with a sterilized knife (because the buds of hemp are small, you can't break them off with your hands). Each time it is cut, the knife is disinfected once, and then the hemp body is slightly exposed to the sun, so that the exudate slurry of the cut part is dried into a film. After the film is formed, don't continue to dry, take it back and plant it immediately. After planting, many bud eyes on the hemp body can sprout more new hemp successively, some of which grow into arrow hemp, some grow into white hemp, and some grow into small hemp. A large white hemp can produce several arrow hemp, white hemp and a lot of millet hemp. During the harvest of Dongfeng 3 team of Dishuipu Commune in Ningqiang County, Shaanxi Province in the spring of 1975, there was a withered white hemp with an original weight of 20 grams, and eight arrow hemps (weighing 0.925 kilograms), seven white flax (weighing 0.15kg) and 78 flax rice were grown all over the body.
The number of Arrow hemp and white hemp is mainly determined by the nutrition and degree of Armillaria mellea. If the supply of nutrition is sufficient, there will be more arrow hemp, white hemp and millet hemp.

Sexual reproduction and seed production techniques of wild Gastrodia elata
Guizhou is the third largest province in the production of traditional Chinese medicine in China. It has been approved by the Ministry of Science and Technology as a national modern science and technology industry base province of traditional Chinese medicine. Traditional Chinese medicine is an important pillar industry in our province. At the same time, Yinjiang has become one of the first batch of traditional Chinese medicine base counties in our province. In order to make full use of the advantages of traditional Chinese medicine resources and transform the abundant wild Gastrodia elata into economic advantages as soon as possible, the principle of "sexual reproduction and sowing technology of Gastrodia elata seeds" successfully researched by Professor Xu Jintang of Chinese Academy of Sciences was introduced. Indoor seed production and cultivation were carried out at Zeng Jiyong's home of Luochang Township. After pollination,

The method of selecting and purchasing Gastrodia elata strains and Gastrodia elata seeds
1. Armillaria mellea: some Armillaria mellea varieties have high yield and high quality, while others do harm to Gastrodia elata, so farmers must be careful when introducing them. Our company promotes Armillaria mellea Amur9 selected by the Institute of Pharmaceutical Plant of Chinese Academy of Medical Sciences from many varieties at home and abroad. The large-scale popularization and application of this variety shows that it has strong vitality, dense branches, high fruiting rate, high yield and high quality, and is the first choice for planting Gastrodia elata. 2. Germinating bacteria: the germination of Gastrodia elata seeds must be provided by the seed embryos infected by the hyphae of a class of fungi of the genus Pleurotus ostreatus.
