Abstract

The invention discloses a preparation method and application of a special fertilizer for astragalus planting. The preparation method of the special fertilizer for astragalus planting comprises the following steps: S1, preparing an inducer solution, preparing SNP into a solution with distilled water, S2, fermenting green manure, S3, preparation of nitrogen-fixing bacteria solution, respectively culturing nitrogen-fixing bacteria T16 and T21 to make bacteria solution, S4, mixing green manure with elicitor solution and nitrogen-fixing bacteria solution to prepare solid fertilizer. The present invention prepares solid fertilizer by mixing the stems and leaves of Astragalus membranaceus with three kinds of elicitors and two kinds of nitrogen-fixing bacteria after fermenting. The amount of polysaccharides and the accumulation of polysaccharides in Astragalus root were significantly increased. Moreover, the special fertilizer of the present invention can increase soil nutrient content, so that organic matter, total nitrogen, phosphorus and potassium, and available nitrogen, phosphorus and potassium contents in the soil are all increased. In addition, the special fertilizer for astragalus of the present invention has a simple manufacturing method and low investment cost.

Description

technical field [0001] The invention relates to the technical field of astragalus cultivation, in particular to a preparation method and application of a special fertilizer for astragalus cultivation. Background technique [0002] Astragalus is a plant with both medicinal and edible uses, and its medicinal use has a history of more than 2,000 years. Astragalus is rich in a variety of bioactive components, the most important and most researched are flavonoids, saponins and polysaccharides. Food tonic or medicinal tonic Astragalus can strengthen the heart, improve immune function, and has anti-aging effects, and is widely used in cardiovascular diseases. Astragalus membranaceus in Shanxi Province officially became a national authentic medicinal material in 2004, and the most famous one is the Astragalus membranaceus produced in Hunyuan, Datong. Hunyuan's high terrain, cool climate, abundant sunshine, loose soil and rich nutrient elements, and unique ecological environment pr...
