The effect of sexual reproduction of Gastrodia elata is good.

Gastrodia elata is the leading product of traditional Chinese medicine in our province. As the planting quality of Gastrodia elata deteriorates year by year and the disease is serious, the yield of Gastrodia elata is low and the benefit is poor. How to solve this problem, Fengcheng Yulong sexual reproduction demonstration service base experts have a trick: the method of sexual reproduction Gastrodia elata, not only the yield than asexual reproduction Gastrodia elata increased by 2 times, but also greatly enhanced the disease resistance.

What is the sexual reproduction of Gastrodia elata

According to Mo Bingyao, an expert from the demonstration service base of sexual reproduction in Yulong, Fengcheng, asexual reproduction is basically used in the cultivation of Gastrodia elata in our province, that is, direct contact with Armillaria mellea from the original bulb to make Gastrodia elata grow continuously.

The sexual reproduction of Gastrodia elata refers to the selection of strong northeast Artemisia mandshurica, such as red stalk, green stalk and black stalk, which have full terminal buds, no diseases and insect pests, no scars, moderate size, cross-pollination and spore fruit. the process of rice and white hemp harvested by sowing together with germinating bacteria and Armillaria mellea. It is understood that Armillaria mellea and germinating bacteria play an important role in the sexual reproduction of Gastrodia elata. Armillaria mellea is the only nutrient to promote the growth of Gastrodia elata, and its quality directly affects the yield of Gastrodia elata.

How to "plant" sexual reproduction

Mo Bingyao said: first of all, around June, Gastrodia elata seeds and germinating fungus leaves were evenly dipped with Gastrodia elata seeds, and wet coarse sandy soil or sandy loam was selected for sowing to prevent flooding and stagnant water. then spread the mixed germinating fungus leaves evenly on the leaves, then spread the branches on the germinating leaves, put Armillaria mellea next to the branches, and cover them with sand, so that the first layer of sowing is finished. According to the above order, sow the second layer, and finally cover the soil with leaves to prevent light and Rain Water from scouring. After sowing, water should be irrigated once every half a month to promote the germination of Gastrodia elata to form protocorms, but it should be noted that there should not be a large amount of fruit water, which will rot the germinated seeds. In November, Gastrodia elata can be taken and stored or planted at the same time. Mo Bingyao said that if separate planting is carried out during the dormant period of Gastrodia elata, the yield will increase by 15% and 20%.

In Liberty Village, Baiqi Town, Fengcheng City, villager Kang Jingwei made use of the technology of sexual reproduction of Gastrodia elata. He said happily that his family produces more than 1000 kilograms of dry products Gastrodia elata per mu, and the market price of Gastrodia elata is as high as 136yuan per kilogram and the lowest is 50 yuan. in this way, planting Gastrodia elata can bring him a maximum net income of 50,000 yuan a year and a minimum of 20,000 yuan.
