How to grow Gastrodia elata to get high yield?

How to grow Gastrodia elata to get high yield? What do you need to pay attention to? Netizens are also asked to help introduce the three high-yield methods of Gastrodia elata, which are listed below for netizens' study and reference. Method 1. From the improvement method of Armillaria mellea, the strain of Gastrodia elata was cultivated by the new method: the new strain was obtained by the new method. The new method is to use the latest biotechnology to detoxify the bacteria, which is by far the most advanced method to obtain strains. The traditional Armillaria mellea strain has the best effect when it is obtained by tissue isolation or spore isolation, and most of the general units or individuals use the purchased mother species for re-expansion, so the cultivation effect is not good. 2. Select new strains: pure isolated strains within three generations are required. The pure isolated strain referred to in this paper refers to the Armillaria mellea strain that uses the latest biotechnology for detoxification; the third generation, that is, the first generation of virus-free Armillaria mellea, is only subcultured once, that is, it is used for the production of secondary and tertiary species, and does not continue to expand. The traditional Armillaria mellea strains do not carry out detoxification treatment, and due to the need of quantity, they are continuously expanded, and some even unrestricted transfer culture, resulting in the decline of strain vitality and serious degradation of strain characteristics. After being used in production, the mycelium can not meet the needs of Gastrodia elata growth, and the cultivation results can be imagined. 3. Select new strain cultivation materials: the cultivation of fungus materials should make use of the oak of the current year and the honey ring bacteria treated with detoxification treatment. After about 4 months of inoculation, the hyphae can go deep into the subcutaneous xylem of oak. On the surface, the bark is tight and there is no shedding phenomenon. Cut and check, the subcutaneous hyphae are dense, indicating that the cultivation can be carried out successfully. When Armillaria mellea and Artemisia mandshurica are directly used for cultivation, the amount of strain is slightly larger, and the effect is the same. It should be noted that Duan wood should be broad-leaved trees, can not use pine, fir, cypress, camphor and other tree species, try not to use poplar, paulownia and other soft tissue tree species. After one year of use, the fungus can be used as mycelium transmission interval, not directly as cultivation material. Second, from the selection and improvement of Gastrodia elata species 1, the use of high-tech Gastrodia elata species: the latest technology is to carry out sexual hybridization of Gastrodia elata, the hybrid advantage can enable people to obtain ideal production results; traditional flax species, mostly small hemp rice produced by "handed down from generation to generation", therefore, it is difficult to have a good cultivation effect. 2. Adopt Gastrodia elata species with high survival rate: the best seed is white hemp, and 10-50 grams is suitable for a single; the most important thing is that the individual should be complete, no mechanical damage, no disease spots, no pests, etc., observed in strong light, the whole body of the seed is transparent, without any shadow attachment. 3. Select Gastrodia elata species with high yield: this is the final result of hybrid Gastrodia elata. Generally, the yield of ordinary Gastrodia elata is low, and the maximum yield of 5 kg is good, while the yield of hybrid Gastrodia elata can reach more than 20 kg or even higher. Third, improve the yield method from the aspect of cultivation. 1. Select a suitable planting site: the ideal cultivation site should be warm and moist, not cold, dry or stagnant water, generally in wild wasteland, forest gaps, hillside shade and sandy soil, and can also make full use of indoor, basement, cave, courtyard, vines hidden open space cultivation, in short, artificially create an environment suitable for Gastrodia elata growth. Gastrodia elata can be cultivated in any area. 2. Scientific management: the cultivation technology of Gastrodia elata is relatively simple, and the basic operation can be learned at the level of education. After sowing, Gastrodia elata is only managed in terms of humidity and temperature. However, to adhere to scientific management, specific cultivation management to achieve: first, the site soil to maintain a certain moisture content, timely watering in times of drought; second, the temperature in the cultivation border (pond) is not higher than 28 ℃; third, to control moisture, continuous rain to clear ditches and drainage; finally, build a shed for shade to avoid high temperature and rotting flax. 3. Timely harvest of Gastrodia elata: practice has proved that timely harvest is a very important link, but this point is often ignored in the cultivation of Gastrodia elata, which finally leads to the emergence of "hollow hemp" and so on. Gastrodia elata, which is generally cultivated after November, must be harvested for a year, and for those cultivated in spring, do not delay the harvest time, so as not to cause rotten hemp and moth, if bolting occurs, it will have no commercial value.
