Key Technical Points and Detailed Methods for Sexual Propagation of Gastrodia elata

Early breeding and early sowing are important measures for shortening the growth cycle of Gastrodia elata. The elevation of Gastrodia elata growing areas is all above 1500 m, the temperature is relatively low, and the fruit harvesting period for breeding is from July to [month]. Because Gastrodia elata is bred in the same year and sown in the same year, attention must be paid to keeping to the season. To shorten the production cycle of Gastrodia elata, breeding can be carried out in low-elevation high-temperature areas or in greenhouses. When digging Gastrodia elata in winter, according to the requirements for selecting seed tubers, leave enough seed tubers for the next year. Cover the seed tubers well with soil so that they maintain a certain temperature and humidity, and in late February of the following year greenhouse breeding can begin. Also pay attention to controlling the temperature and humidity of the greenhouse well. By April, the fruit can be harvested, and sowing can then follow. In this way, the seeds sown that year can germinate into mi-ma or small bai-tou-ma, and by the winter of the second year jian-ma will have grown, which can shorten the growth cycle of Gastrodia elata. Shortening the production cycle of Gastrodia elata can save fungal wood and reduce consumption: first, thin wood (with a diameter of 1 cun) can be used to cultivate Gastrodia elata; second, thick wood can be used a second time.
