Recently, the author received a letter from many farmers' friends and asked how to store the gastrodia species. During the production process of gastrodia, rotten species often occur and cause losses. The author believes that storage of Gastrodia should be a good "three levels." The first is harvesting. Gastrodia elata is excavated in spring and winter, in which, in the winter, excavation of gastrodiae, fresh, disease-free pests and non-injurious small gastrodia are singled out, and after 1-2 days, part of the water is air-dried and then stored for another year. use. The second is the temperature off. The gastrodia species that have been partially air-dried are placed in tile ponds, large tile basins, or wooden boxes in layers. Each layer was covered with moist sand, first with yellow sand, and each layer of gastrodia was covered with a layer of sand. Storage temperature should be controlled between 2 ~ 5 °C, in order to avoid excessive temperature changes caused by Gastrodia species rotten. The third is the humidity off. During storage, it should be checked frequently. If spotting or mildew is found, the moisture content of the sand should be reduced in time and the ramie should be singled out. If the hemp seeds are found to have atrophy and shrinkage, the sand should be mixed with hot water.
