Successful Research on Timber-free cultivation of Gastrodia elata in Guizhou

The fragile ecological environment in the west is in urgent need of protection, but the poor people in the west are in urgent need of logging and planting Gastrodia elata to get rich, so environmental protection and well-off society have become a pair of inextricable contradictions. Nowadays, with the maturity and promotion of the cultivation technology of Gastrodia elata in Yunlong Gastrodia Development Co., Ltd., Dafang County, Guizhou Province, this contradiction is easily solved. Dafang County is located in the northwest of Guizhou Province. Due to the unique geographical environment and climatic conditions, the generous Gastrodia elata has a large size, transparent texture, gastrodin content and beneficial trace elements such as molybdenum, chromium, rubidium, cobalt and copper, which are far higher than those in other areas. The product is outstanding at home and abroad, known as "China Gastrodia elata in Guizhou, Guizhou Tianma generous". Yunlong Company is a private science and technology enterprise integrating Gastrodia elata research, breeding, planting, deep processing and packaging. In 1998, the company undertook the regional spark science and technology project: Gastrodia elata non-timber cultivation technology research. Through nearly a hundred repeated experiments, Yunlong Company finally used generous wild Gastrodia elata as the provenance, successfully developed the technology of sexual reproduction of Gastrodia elata which is suitable for the local climate characteristics, and according to the biological characteristics of Armillaria mellea, after scientific treatment of rural corn stamens, grain husks and other wastes instead of wood planting, not only reduce the planting cost, simplify the process, improve the quality and increase the yield. But also fundamentally solved the contradiction between Gastrodia elata cultivation and ecological protection. In June 2002, Chen Yiyu, vice president of the Chinese Academy of Sciences and academician of the Chinese Academy of Sciences, led an expert group after a generous inspection that Yunlong's sexual reproduction technology of Gastrodia elata filled the gap in the cultivation of Gastrodia elata in Guizhou. There is no doubt that non-timber cultivation is a revolution in the history of Gastrodia elata cultivation. Guo Xiangwen, general manager of Yunlong Company, said that Gastrodia elata is a rootless and leafless plant, which does not need to absorb nutrients from the soil and carry out photosynthesis. Its nutrient source comes from Armillaria mellea, and the main nutrition of Armillaria mellea comes from wood. Therefore, wood must be used to grow Gastrodia elata in the past. Since the 1970s, many experts and scholars have done a lot of exploration and research on the selection, breeding, standardized planting, processing, storage and transportation of wild Gastrodia elata, resulting in the continuous improvement of the quality and the continuous increase of output. Thousands of farmers have been able to get rid of poverty and become rich by planting Gastrodia elata, but the problem of consuming a lot of wood in planting Gastrodia elata has not been solved. What experts and drug farmers have done is the choice of wood texture, the ratio of quantity, the distribution of size and diameter, the depth of fish scale mouth and the selection of soaking solution, but failed to find a substitute for wood. It is estimated that planting one mu of Gastrodia elata requires 20,000 kilograms of 5 cm thick hardwood, which is equivalent to cutting down 7 to 8 mu of mountain forest. Yunlong Company planted 400 mu of Gastrodia elata with non-timber cultivation technology in 2002. in the past, 2800 to 3200 mu of lush trees would have disappeared. Dafang County plans to develop Tianlin to plant 20, 000 mu in the next five years, which in the past means that 140000 to 160000 mu of wood will be cut down by axe. However, from now on, the traditional planting method of "digging meat and tonifying sores" of Gastrodia elata at the expense of the ecological environment will never return with the birth and promotion of non-timber cultivation technology.
