Method for cultivating gastrodia elata by imitative-ecological bacterial bed under forest

Abstract

The invention discloses a method for cultivating gastrodia elata by an imitative-ecological bacterial bed under forest, which is a novel method developed for solving problems of low germination rate,severe microbial contamination, high consumption of forest resource and the like. The method includes the steps of seed dressing, cultivation of original seeds by nutrient packs, harvesting of original seeds, preparation of the bacterial bed, cultivating, and harvesting of gastrodia elata ; in cultivation of original seeds by nutrient packs, symbiotic germinated strain leaves treated by seed dressing, level-3 strain of halimasch, and twigs are placed in plastic bags by a layering way respectively, gaps are filled with a mixture of humus and 10% of plant ash which are stirred uniformly, and theplastic bags are placed on indoor cultivation racks for strain cultivation; the preparation of the bacterial bed refers to digging holes (each is 50cm*60cm in size), at position where is 2m distant from the trunk, of the root, along the lateral side of the root, and then uniformly setting sticks among lateral roots. The method has high practicability and high convenience in planting, and can achieve the effects of shortening cultivation time of gastrodia elata, reducing influence to seed germination of gastrodia elata from weathers, avoiding cavities, saving bacterial materials and reducing cost.

Description

technical field [0001] The invention belongs to the technical field of Gastrodia elata production, and in particular relates to a method for cultivating Gastrodia elata by utilizing an imitation ecological fungus bed under forests. Background technique [0002] Gastrodia elata is a saprophytic herb of the Orchidaceae and Gastrodia genus. Gastrodia elata likes a cool and humid environment. Excessively high summer temperatures in low-altitude areas will inhibit the growth of Gastrodia elata and Armillaria elata. At high altitudes, when the temperature is too low, it will also affect Gastrodia elata growth. The artificial cultivation of Gastrodia elata makes the cultivation areas widely distributed across the country. As long as the high temperature in summer, the low temperature in winter, and the humidity are well controlled according to the growth conditions required for the growth of Gastrodia elata and Armillaria elata, it can be grown in plains, basins, and even hot south...

Problems solved by technology

[0004] In the process of traditional commercial Gastrodia elata cultivation, the mode of "bacteria stick + new stick" is often used to provide nutrition for the growth of white hemp, and it is necessary to cut down a section of wood as a fungus material, which consumes a lot of forest resources and affects the sustainable development of gastrodia elata planting; it is easy to cause The emergence of competitive bacteria accelerates the degradation of Armillaria armillaria, and once the contamination of bacteria occurs, it will spread rapidly in the entire cultivation hole, resulting in a reduction or failure of Gastrodia elata, resulting in "empty nests", which seriously affects farmers' enthusiasm for planting Gastrodia elata

[0005] At present, there are mainly two planting methods for asexual propagation of Gastrodia elata. One is planting with seed-mixed fungus leaves, Armillaria branch, and fresh section wood. The advantage of this method is that it saves manpower by planting once, and the germination and Armillaria grows at the same time, but there are two problems: first, the conditions for seed germination are not controlled, and if the weather is too dry, the germination rate will be very low; second, in the case of unsuitable climate conditions, Armillaria grows slowly , if the seeds germinate, but Armillaria is not well-grown, the protocorm will not be connected to Armillaria, and it will lack nutrients and die

[0006] The other is to cultivate the Armillaria fungal material first, and then plant the fungus leaves mixed with the seeds together. The advantage of this method is to ensure that Armillaria Armillaria grows well and provide sufficient nutrition for the growth of protocorms in the later stage. , but there are still two problems: First, according to the experiments of Xu Jintang et al., the extract of Armillaria armillaria has inhibitory effect on the germination of Gastrodia elata seeds. The germination rate of the seeds will be reduced if Armillaria is planted together with the fungus leaves mixed with the seeds; secondly, it will take some time for the seeds to germinate after being planted, and during this time Armillaria is in a wasteful growth and consumes wood, Shorten the utilization time of wood
