What should be paid attention to when planting Gastrodia elata in boxes
High quality rods must be selected for ①, and the rods with many young cords and evenly distributed are the best. ② sticks must be free from contamination by miscellaneous bacteria. ③ if there is not much fungal cord on the stick, some secondary or tertiary solid strains of Armillaria mellea can be added appropriately. It can also be covered with a layer of culture material for Armillaria mellea (because there is Armillaria mellea in the material). If ④ put a fungus material parallel to 3 cm next to the high-quality stick, it can continue to provide Gastrodia elata nutrition after it is grafted on and Armillaria mellea grows in the later stage. But not near the fungus.

What effect does summer high temperature have on Tianma
Gastrodia elata has little effect on Gastrodia elata under the condition of high temperature of 32-34℃ in low altitude hilly area for 10 days (240 hours), and can produce arrow hemp, but the yield of Gastrodia elata will be affected when high temperature lasts for 15 days (360 hours). Therefore, gastrodia elata high temperature tolerance base point is higher. Tianma summer is not only related to the absolute high temperature value, but also depends on the duration of high temperature. Because of the monthly temperature difference and the day-night temperature difference under outdoor natural conditions, and the artificial cultivation to take shading and other regulatory measures

Five reasons why it can lead to low yields
Recently, editors often receive some consultation calls, complaining that the yield of gastrodia elata cultivated by them is not high, some even lower than 3 kg/square meter, the reporter specially consulted Cao Debin, an expert of Gastrodia elata of Provincial Academy of Agricultural Sciences, according to his introduction, according to the growth principle of gastrodia elata, there are many reasons for low yield of gastrodia elata, he listed the following five reasons, farmers friends can according to their own production conditions, see whether there are the following situations: First, Armillaria mellea has been passed many times, aging and degeneration. Armillaria mellea is the only source of nutrition for Gastrodia elata, so the quality of Armillaria mellea is high and low.

Cultivation techniques of Gastrodia elata
Black Gastrodia elata has a good shape, high drying rate (3 jin of fresh products dry 1 jin of dry products), excellent quality, and the price of Gastrodia elata is three or four times higher than that of Gastrodia elata and Gastrodia elata. The reason why the price of Gastrodia elata is high, but also because of artificial cultivation, or wild distribution of the area and quantity are very small. Therefore, the artificial cultivation of Gastrodia elata needs to grasp the following key points: 1. Cultivation area. Gastrodia elata is mostly distributed in Yunnan, Guizhou, Sichuan and three northeastern provinces. In the Yangtze River basin, Gastrodia elata is distributed or cultivated only in the mountains above 1500 meters above sea level. So people

Why does Gastrodia elata rot?
This is because Gastrodia elata cultivated in border cellar is covered with 40 cm thick fresh leaves and unripe fallen leaves to protect against cold before freezing. Sawdust and fallen leaves themselves contain a certain amount of water and organic matter, and 40 cm thick fallen leaves accumulate together. In the process of oxidation reaction (fermentation), a large amount of heat is generated, which promotes the heating of Gastrodia elata border cellar, and the temperature can reach 34 ℃. If you do not pay close attention to observation, control the temperature and humidity in time. Even in winter, Gastrodia elata will burn over a long time. In the alpine forest area of Jilin Province, it can be covered with 15% before freezing.

High benefit of cultivating Gastrodia elata in courtyard
At the beginning: the artificial cultivation of Gastrodia elata has a special law, and the technical level directly affects the yield of Gastrodia elata. Comrade Zhang Youyun of Yunzhou Gastrodia Research Institute in Heze City has studied the cultivation techniques of Gastrodia elata since 1992 from Mr. Xu Jintang, a researcher at the Institute of Medicinal plants of the Chinese Academy of Sciences, the father of Gastrodia elata. Over the past ten years, he has explored a set of effective cultivation techniques of Gastrodia elata and accumulated a wealth of practical experience. In order to enable more Gastrodia elata enthusiasts to learn and master the cultivation techniques of Gastrodia elata, this newspaper has opened a column on "lectures on cultivation techniques of Gastrodia elata" from now on.

How to store gastrodia elata for winter
Hemp seeds can be stored in a pit in the cellar. First dig pits in the cellar, the size of the pit depends on the number of hemp seeds, pit depth 45-50 cm. hemp seed should be removed from the vegetative propagation stem, air 1-2 days re-entry cellar. Sand with a moisture content of 20% should be selected as filler. Sand moisture content is too large, too small for hemp seeds are unfavorable. After the pit is dug, put a layer (3 cm thick) of sand from small rice grains to sorghum grains at the bottom layer, put a layer of hemp seeds, put 4-5 layers of hemp seeds in total, and put 5-6 cm thick sand cover at the top layer. Each layer of hemp seed must be placed separately, hemp and hemp
