A wild growth imitating cultivation method for astragalus propinquus

Abstract

The invention provides a wild growth imitating cultivation method for astragalus propinquus. The method comprises the steps of 1) land selection and soil preparation: digging planting holes after selecting a plantation, drying dug-out weeds and root hair to prepare natural fertilizer, mixing river sand, the natural fertilizer and land soil uniformly and placing the mixture in the planting holes; 2) base fertilizer application: feeding water into the holes thoroughly before transplanting and spreading mixed fertilizer with a thickness of 2-3mm after the water permeates soil thoroughly, wherein the mixed fertilizer is formed by mixing livestock manure, plant ash, urea, calcium ammonium nitrate and vermiculite power; 3) transplanting; 4) field management; 5) disease and pest control; 6) harvesting and processing. The method selects shady wasteland in mountainous areas or half-mountainous areas, does not occupy fertile farmland, selects growing environment similar to that of wild astragalus propinquus, enables astragalus propinquus to grow naturally and reduces human factor interference as much as possible, thereby guaranteeing the original medicinal purpose quality of astragalus propinquus. With the planting method, astragalus propinquus has the advantages of high survival rate, high medicinal material quality, high yield and low disease and pest damage incidence rate.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and in particular relates to a method for imitating wild cultivation of Astragalus membranaceus. Background technique [0002] Astragalus is the dried root of the leguminous plant Astragalus mongolica or Astragalus membranaceus, and is one of the commonly used Chinese medicinal materials. Astragalus has a medicinal history of more than 2,000 years. It is slightly warm in nature and sweet in taste. It has the functions of invigorating qi and strengthening the exterior, diuresis, detoxification, and granulation. Astragalus is a deep-rooted plant, suitable for growing in sandy loam with deep soil, fertile, loose, and good drainage; it likes cool climate, strong drought resistance; cold-resistant, afraid of heat and waterlogging; too high temperature often inhibits growth; too wet soil It often causes root rot; the seed coat is relatively hard, and germination does not l...

Problems solved by technology

[0004] The purpose of the present invention is to: provide a method for imitating wild cultivation of Astragalus membranaceus, moderately control the interference of human factors on Astragalus membranaceus, create a growth environment imitating wild for Astragalus membranaceus, make Astragalus membranaceus imitate natural growth, and solve the chemical problem in the existing artificial planting Astragalus membranaceus technology. Large amounts of fertilizers and pesticides are used frequently, resulting in the decline of resistance and medicinal properties of Astragalus
