Special fertilizer for Astragalus membranaceus, fertilization methods for improving the yield of Astragalus membranaceus

Abstract

The invention provides a special fertilizer for astragalus, which comprises organic fertilizer and chemical fertilizer; the mass ratio of the organic fertilizer to the chemical fertilizer is (80-90): (6-7); the organic fertilizer comprises bean green and grass P1; The mass ratio of described soybean meal and grass P1 is (0.5~1.5): (0.5~1.5); Described soybean meal is compounded by soybean meal and Trichoderma viride; The mass ratio of described soybean meal and Trichoderma viride powder is (80 ~150): 1; the grass P1 is obtained by compounding the phosphate-solubilizing bacteria P1 bacterial liquid in the logarithmic growth phase with peat soil. Compared with the prior art, the present invention is based on the fertilization technology of the joint action of organic fertilizer and calcium fertilizer. Organic fertilizer is used to activate the soil, improve the structure, and fertilize the soil, and then combine the application of chemical fertilizers to replenish soil nutrients in time to improve soil organic matter. and calcium content, increase the yield and active ingredient content of Astragalus membranaceus; at the same time, the special fertilizer for Astragalus membranaceus is used as a one-time base fertilizer to realize scientific fertilization and management.

Description

Special fertilizer for Astragalus, fertilization method for increasing the yield of Astragalus technical field The invention belongs to medicinal plant planting technical field, relate in particular to a kind of special fertilizer for Astragalus, improve Astragalus output Fertilization method. Background technique Astragalus is leguminous plant Mongolian Astragalus (Astragalus membranaceus Bungevar.mongolicus (Bge.) Hsiao) or the dried root of Astragalus membranaceus (Fisch.) Bge.). Mongolian Astragalus Sweet in taste, slightly warm in nature, containing saponins, sucrose, polysaccharides, various amino acids, folic acid, selenium, zinc, copper and other trace elements, modern research It shows that Astragalus has enhanced immune function, liver protection, diuresis, anti-aging, anti-stress, antihypertensive and a wide range of antibacterial effects. The main producing areas of astragalus have a large amount of Mongolian astragalus medicinal materials exported to ...

AI Technical Summary

Problems solved by technology

At present, Astragalus membranaceus is generally planted in sandy land or semi-fixed sand dunes, dry old riverbeds, lake basin lowlands, deserts, and semi-desert areas. These soils have poor structure, low organic matter content, and poor fertilizer retention capacity, resulting in low yields of Astragalus membranaceus and low medicinal efficacy. uneven

[0004] At present, the management of farmers' existing fertilizers is still based on traditional experience. The application of fertilizers only considers the input of nitrogen, phosphorus and potassium fertilizers. Some better ones can use livestock manure, but it does not consider the harm caused by excessive heavy metal content in livestock manure, and does not consider organic fertilizers. Fertilizer has a positive impact on the utilization rate of soil nutrients, and the positive effect of calcium fertilizer on the active substances of Astragalus is not known. During the fertilization process, organic fertilizer and calcium fertilizer were not used, and their effects were not considered, which led to excessive input of chemical fertilizers. On the one hand, fertilizer The utilization rate is low, a large amount of nutrients are lost, causing environmental pollution. On the other hand, too much fertilizer input also greatly increases the planting cost of farmers, and the planting efficiency is low.
