How to cultivate Gastrodia elata?
How to cultivate Gastrodia elata? The production benefit of Gastrodia elata is relatively high. since the fourth quarter of 2006, the purchase price of fresh flax is generally 20 yuan per kilogram, and the planting investment in the first year is slightly higher, and the production benefit is about 200 yuan per square meter. After the second year, the cultivation can be expanded by using self-produced flax seeds, and the benefit is higher than that of the previous year. Second, it is expected that the market price will rise by a large margin by the end of this year. At present, the average purchase protection price has reached about 30 yuan per kilogram. From one side, we can see the market demand state of Gastrodia elata. Where there is demand, there is a market; if there is a market, there must be production; third, due to the increasing reputation and status of traditional Chinese medicine in the world, foreign consumers are also favored by Gastrodia elata and other products. Gastrodia elata health products are also gradually rising in foreign markets, so that Gastrodia elata exports rise synchronously on the basis of increasing domestic demand, so the market potential of Gastrodia elata is huge and the prospect is promising. Calculated according to current prices, generally, when planting a square meter of Gastrodia elata for the first time, it needs "Luji No. 2" Gastrodia elata hybrid and Armillaria mellea to be about 85 yuan, plus sand, Duan Mu, etc., with a total investment of about 120 yuan, and a general output of about 30 jin. The current market price is about 200 yuan per square meter (excluding the remaining hemp species, it can expand more than 3 square meters per square meter). The gully cultivation of Gastrodia elata is a new technology studied and popularized for many years. according to analysis, the fundamental reason why this technology can greatly increase the yield of Gastrodia elata is that: first of all, the underground temperature is suitable and is basically in a constant state all the year round. There is basically no problem of dormancy period in the growth process of Gastrodia elata. Secondly, the humidity of underground water is stable, as long as there is no stagnant water and good soil permeability, there will be no problems such as non-uniformity and imbalance of dry, wet and wet water. Finally, it is basically not affected by the ground environment. Specific cultivation techniques, mainly have the following points: ⑴ selected strains or materials: strain plus section wood cultivation, it is required to use a generation of isolated bacteria, no diseases and insect pests. ⑵ selection of hemp seed: it is required to choose sexual hybrid hemp seed, without any damage, disease spot and insect pest. ⑶ chooses a good site: slightly higher but not dry, soft soil without stagnant water and no possibility of stagnant water, good permeability. ⑷ trenching treatment: trenches with a width of about 60-80cm and a depth of 80-100cm are dug in the north-south direction; the bottom of the ditch is covered with a layer of coarse sand about 10-20cm, irrigated once, and then sprayed or irrigated with water 800x phoxim solution and 800x carbendazim solution. ⑸ sowing preparation: when using bacteria for cultivation, it is necessary to cut down trees 2-3 days in advance, or soak the dried wood in clean water and transport it to the cultivated land before sowing. ⑹ sowing: same as conventional sowing. A rain shelter should be set up at the top of the ditch to prevent Rain Water from entering the ditch directly. ⑺ management: watering once on the 10th day of sowing; building short shade such as weeds and corn stalks along the ditch. After that, it should be watered every 20 days or so; in the low temperature season, the cultivation ditch can be covered with plastic film and covered with a layer of straw to keep warm. According to the production practice and investigation for many years, the asexual reproduction and cultivation methods used in Gastrodia elata production have the problems of decreasing yield and quality year by year, so from a long-term point of view, Gastrodia elata must be "changed". The use of sexual hybrids should be promoted to achieve ideal production results. It should be noted that Gastrodia elata hybrids are not only planted for one generation like corn, but are cross-bred and can be used for self-propagation for many years, which can not only maintain the hybrid advantage of Gastrodia elata hybrids, but also reduce the production cost. It is welcomed by the majority of growers and is conducive to the promotion of technology. Click to get more planting techniques of Gastrodia elata

What is the character degradation of Gastrodia elata? The performance of hemp character degradation is that the yield of arrow hemp decreases, the individual becomes smaller and slender; the yield of rice flax and white hemp decreases greatly, ginger or light brown, the stress resistance is poor, and the original yield and characters can not be fully reflected. The reasons are generally as follows: 1. Multigenerational asexual reproduction.

Avoid exposure to the sun, then shake off the blighted seeds and store them. Seed treatment: soak the seeds in warm water of 35 ℃ 40 min before sowing for 24 hours, remove and mix.
