Gastrodiae elata planting method in primitive environment

Abstract

The invention discloses a gastrodiae elata planting method in a primitive environment. the gastrodiae elata planting method comprises the following steps of: excavating local wild sisal hemps and obtaining seeds after generative propagation; seeding and cultivating, and then harvesting hemp seeds as the hemp seeds for planting; collecting, inoculating and cultivating halimasch rhizomorph on local wild gastrodiae elata, and carrying out marking separation for purifying; carrying out expanding cultivation for inoculating fungi materials or fungi bags; continuously cultivating till halimasch fruits; inoculating with marine spores with caps, cultivating to form primary slope strains, and carrying out secondary and third-level expanding cultivation to form production seeds; selecting an environment, such as a region where the wild gastrodiae elata naturally grows or a region where the wild gastrodiae elata has grown once; and carrying out originally ecological cultivation. The gastrodiae elata planting method disclosed by the invention has the capability of cultivating excellent and authentic varieties with stable hereditary character and has greatly-reduced germplasm degradation rate.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a planting method of Gastrodia elata. [0002] Background technique [0003] The traditional Chinese medicine Gastrodia elata (Rhizoma Gastrodiae) is derived from the dried tubers of Gastrodia elata Bl. Due to the improvement of the quality of life, people's demand for gastrodia elata surges, but the environmental resources are becoming increasingly scarce. The chain of interests drives barbaric and over-harvesting, and the wild gastrodia elata resources are approaching the endangered situation. According to research, Gastrodia elata mostly grows in the forests with more humus and moistness in the valley woodlands at an altitude of 700-2800 meters, and also in sunny shrubs and grass slopes. However, from the analysis of the environment of authentic production areas (such as Dafang County, Guizhou Province), the most suitable environment for Gastrodia elata is: cool and humid i...

AI Technical Summary

Problems solved by technology

But its main problems are: (1) The fungi are all transported from different places, so the utilization rate is low and the consumption is high; (2) Due to the relatively narrow location, some of them use continuous cropping, which leads to an increase in pests and diseases, and the degradation of species (3) Planting gastrodia elata requires fungus materials, and for concentrated planting, broad-leaved trees must be cut down to make fungus materials. This undoubtedly conflicts with natural forest protection and ecological environment protection. The lack of fungus materials also limits the development of gastrodia elata planting industry

(4) Due to the expansion of cultivation scale, the provenance of Gastrodia elata has been "greatly shifted", that is, hemp seeds have been introduced from areas with earlier cultivation and larger scale, so that many places with authentic Gastrodia elata medicinal materials have lost their authentic advantages

However, under-forest planting does not solve the problem of the authenticity of medicinal materials—the authentic source of seeds and the authentic coordination of environmental conditions

At the same time, the crop rotation of Gastrodia elata showed problems such as accelerated species degradation, serious pests and diseases, etc.
