Harvesting and processing technology of Gastrodia elata
Gastrodia elata is a perennial parasitic herb. First, the harvest of Gastrodia elata, asexual reproduction, winter planting Gastrodia elata, the following winter or the third spring mining. Gastrodia elata planted in spring was harvested in winter of the same year or in spring of the following year. In the first year of sexual reproduction, the seeds were sown in June, and in November of the second year, 80% were commercial and 20% were seed hemp. Therefore, the harvest time of sexual reproduction can be determined according to the needs of production. Second, Gastrodia elata commodity processing fresh Gastrodia elata after harvest, stacked for 3-5 days began to rot. Therefore, it should be processed in time. Grading should be selected before processing:

Common processing methods of Gastrodia elata
Gastrodia elata processing must be careful, otherwise it will be painstakingly cultivated good gastrodia elata processing into defective products, failure, not good economic benefits. There are three common methods of processing Gastrodia elata: ① Cage steaming method: The method of steaming Gastrodia elata with cage is called cage steaming method. The gastrodia elata processed by this method has bright color and best quality. Will use water to clean the skin of the soil gastrodia elata, divided into large, medium and small three levels were placed in the cage steamed for 10 - 20 minutes, small time to be short, large time slightly longer, to steam through no white heart for the degree.② Rice soup boiling method: use 5

Gastrodia elata is rotten when it is ripe. What's the matter?
Li Zongguo, a farmer from Jinluanshan Village, Jiahe Town, Yunxi County, wrote to ask: I began to learn to grow Gastrodia elata last year. According to relevant introductions, I planted 50 to 60 square meters indoors, and last year's harvest was good. This year I began to expand the planting, or to follow the method of last year. In September this year, I started digging and sold it on the market for only three days. Then I dug again, only to find that all the Gastrodia elata was rotten. How is this going on? Zhang Qiudong, Department of Disease and Pest Control of Provincial Plant Control Station, answered: most of the causes are due to bad environment, such as high temperature, high humidity, poor ventilation and so on.

Three-dimensional cultivation of Gastrodia elata soybean
Gastrodia elata is a kind of traditional Chinese medicine, which can replenish qi, calm shock, nourish liver and stop dizziness, and dispel rheumatism. Strengthen muscles and bones and other effects. In recent years, on the basis of artificial box planting and making full use of the growth characteristics of Gastrodia elata, we have successfully planted Gastrodia elata underground and dwarf crop soybean above ground. According to the investigation and determination of Shuidian Town Agricultural Station, the three-dimensional cultivation of soybean Gastrodia elata produces 200,300kg of commercial dried products per mu, with an output value of 8000-10000 yuan (calculated as 36-40 yuan / kg), and 150,175kg of soybean per mu, with an output value of 360.

Preliminary report on substitute cultivation of Gastrodia elata
Artificial cultivation of Gastrodia elata mainly uses oak, birch, hazel, elm, willow, jujube, locust, wild cherry and other broad-leaved trunks, and the diameter is more than 5cm. For a long time, forest resources have been seriously damaged and are on the verge of exhaustion. Therefore, the research on substitute cultivation technology of Gastrodia elata has gradually become a hot spot. At present, there are precedents for cultivation of Gastrodia elata with corn shaft, shrub seed, bract rice bone, bract rice pulp, branch, straw and so on, but there is no report about the cultivation of Gastrodia elata with cottonseed husk.

Preservation of Gastrodia elata
After processing, Gastrodia elata must be properly preserved to prevent insect moths and mildew, so as not to affect the quality of the product. After the finished Gastrodia elata is made, it should be sealed with a non-toxic plastic containing white paper, or packed with a magnetic altar. Then cover it with clean thick paper and store it in a dry place to prevent it from returning to moisture and mildew. At the same time, it is re-fumigated with sulfur before the annual moth season (March-April) to prevent moth.

Preliminary harvesting and processing technology of Gastrodia elata
Gastrodia elata, such as fresh sales, as long as it does not collide, do not hit, and no mechanical scars after harvest, then gently brush off the sediment from the flax body with a soft brush and load it into a soft-lined wooden box or plastic box. If the processing of dry hemp, the method is more complex, generally with water boiling or cage steaming method for ripening, and then drying or sun drying. Cage steaming and Kang drying are generally used in actual production, and the operation process is as follows: grade selection-washing-steaming-Kang drying. 1. The grades are graded according to the weight of Gastrodia elata, that is, less than 50 grams and 50-

Harvest season and processing of Gastrodia elata
Sexual reproduction, sowing in June and July, and harvest in November of the following year. Asexual reproduction, winter sowing, harvest in November of the following year, spring sowing, harvest in November of that year or spring of the following year. After ploughing, the big ones are used as medicine, and the small ones are used as seed hemp. Medicinal Gastrodia elata, washed away from the soil, divided into 2-3 grades, put into water (with a little alum), large boiled 10~15min, small boiled 5~10min, to boil the heart shall prevail, from the dark to the bright, there is no black heart and transparent is ripe. Then fumigate with sulfur for 20 ~

Reproduction of Gastrodia elata
First, asexual reproduction 1. The period of cultivation. Generally, winter planting is carried out in November, spring planting is carried out from March to April, and winter planting is better. two。 Seed hemp choice. White hemp and rice hemp is the best, each weight 5 grams-10 grams is the best. The seed flax with no disease spot, no trauma, no frost injury, no decay, spindle shape and obvious bud eyes was selected. Some also use arrow hemp as seed hemp, but the top bud should be removed. 3. The amount of hemp used. It depends on the size of the seed and the number of fungus in a litter. Generally, 9-10 fungi are used in each nest.

Grasp the three key points for the high yield of Gastrodia elata
Due to the sharp decrease in the production area of Gastrodia elata in recent years, the market demand is on the rise, and the price of Gastrodia elata is on the rise. Recently, many growers have called to inquire about the cultivation techniques of Gastrodia elata. The reporter interviewed Professor Cao Debin of Shandong Academy of Agricultural Sciences, an expert on Gastrodia elata, and now makes an important introduction to the high-yield cultivation techniques of Gastrodia elata, hoping to be helpful to the majority of farmers. First, Armillaria mellea should be "three new" 1. New technology: new methods to obtain new strains. The new method is to use the latest biotechnology to detoxify the bacteria.
