Economic benefit and cost Accounting of sexual Reproduction of Gastrodia elata
Breeding and cultivation of sexual reproduction of Gastrodia elata (also known as sexual breeding of Gastrodia elata): we have successfully studied the new technology of sexual rapid growth of Gastrodia elata hybrids in summer. That is, using the "Yihongyou 1" Gastrodia elata hybrid capsule (pollen) seeds, germinating bacteria and Armillaria mellea species "synchronous cultivation", sowing 20 "Yihongyou 1" hybrid Gastrodia elata capsules per square meter, 2 bags of germinating bacteria, 3 bottles of Armillaria mellea, and half a bottle of insecticide. Half a package of auxin. Supplemented by the right amount of wood sticks, river sand planting. The original seed of 0 generation of sexual hybrid Gastrodia elata can be harvested in 5 months, and the size of each seed is between 2 and 7 grams. Then transferred to asexual planting, that is, the harvested flax seeds were cultivated synchronously with Armillaria mellea, insecticidal, auxin, wood stick and river sand, which could be expanded by 10 square meters and 20 square meters. In the same year, seed breeding benefited from the same year, with a success rate of 100%, which is the only shortcut for planting Gastrodia elata to obtain the best economic benefits.
Matching supply of sexual reproduction of Gastrodia elata: "Yihongyou 1" sexual hybrid Gastrodia elata capsule, leaf germination and Armillaria mellea can be supplied from May to June. Every 10 sets of 1 group 800 yuan, can grow 10 square meters. There are 200 capsule species of Gastrodia elata "Yihongyou 1", 20 bags of leaf germination bacteria, 30 bottles of Armillaria mellea, 5 bottles of insecticidal, 5 packets of auxin (double-acting hormone powder) and 1 cultivation technical data. Fresh parcels are mailed or consigned by train.
The cultivation cost of sexual reproduction and breeding of Gastrodia elata was calculated as follows: a total of 80 yuan of capsule species, germinating bacteria, Armillaria mellea, insecticides (Chongling) and auxin (double effect powder) needed for sexual reproduction in 1 square meter. 33 kilograms of fresh wood sticks are 6.6 to 9.9 yuan (including 30 kilograms of thick sticks about 4 centimeters in diameter and 3 kilograms of fine branches about 2 centimeters in diameter) and 0.25 cubic meters of sand in clean medium river sand. The labor cost and other expenses are about 5 yuan, and the total investment is about 100 yuan. The original seed of 0 generation of sexual hybrid Gastrodia elata can be harvested 4-5 months after sowing, and the current market price is 120 yuan / kg. If the minimum output is 3 kg and the market price is half of 60 yuan / kg, the output value is 180 yuan, and more than 20 kilograms of Armillaria mellea can be harvested, worth 20 yuan. The total output value is 200 yuan, minus the cost of 100 yuan, the net income of 1 square meter is 100 yuan. 1 kg sexual Gastrodia elata 0 generation can be propagated (asexual reproduction) cultivation 5 square meters, then, 3 kg Gastrodia elata harvested by sexual reproduction can be propagated and cultivated at least 15 square meters, and 10 square meters Gastrodia elata 0 generation species can be expanded and cultivated 150 square meters, and the breeding harvest in that year, this is the significance of Gastrodia elata sexual reproduction to obtain the best economic benefits. However, the sexual reproduction of Gastrodia elata is very seasonal and can only be carried out from May to June. Therefore, it is very important to seize the opportunity and seize the opportunity.

Production technology of sexual reproduction of Gastrodia elata
In recent years, in the production of Gastrodia elata in our county, we have adopted the technology of direct seeding sexual reproduction of Gastrodia elata seeds to replace the previous asexual reproduction cultivation method, which not only saves labor and time, increases the yield of farmers, but also reduces the amount of wood cutting. it is beneficial to the maintenance of hydraulic engineering in Tongbai Mountain area at the source of the Huaihe River, obtains double benefits and alleviates the contradiction between bacteria and forests. Because the sexual reproduction technology of Gastrodia elata uses the branches, small wood and broad-leaf deciduous leaves of 3~6cm with stem diameter, 4kg can be obtained for every 0.5m2 of cultivation holes in the same year.

Sexual reproduction technique of Gastrodia elata
Early breeding and early sowing is an important measure to shorten the growth cycle of Gastrodia elata. Gastrodia elata planting areas are all above 1500 meters above sea level, the temperature is low, and the breeding harvest period is in July. Because Gastrodia elata is bred and sown in the same year, attention should be paid to the festival season. In order to shorten the production cycle of Gastrodia elata, breeding in low altitude and high temperature area or greenhouse breeding can be used. When picking and digging Gastrodia elata in winter, according to the requirements of selecting the seed of Gastrodia elata, leave enough of the seed of next year. Cover the seed hemp with soil to maintain a certain temperature and humidity, and greenhouse breeding can be carried out in late February of the following year.
