Fertilizer for black soybeans

Abstract

The invention relates to the field of fertilizers, and especially relates to a fertilizer for black soybeans. The fertilizer comprises the following components in parts by weight: 20-25 parts of straw, 10-20 parts of sawdust, 10-12 parts of expanded perlite powder, 1-2 parts of a nitrification inhibitor DMPP, 0.3-0.5 parts of tea saponin, 100-110 parts of cow dung, 12-14 parts of mushroom dregs, 30-40 parts of bean curd residues, 8-9 parts of bacteria powder, 60-70 parts of rice husk powder, 20-40 parts of a potassium fertilizer, 3-5 parts of amino acid, 30-50 parts of a nitrogen fertilizer, 40-50 parts of bentonite, 40-60 parts of Achnatherum inebrians, and 20-40 parts of vinasse. The fertilizer overcomes the disadvantages of prior art, the preparation method is simple, and the fertilizer for black soybeans has the advantages of high utilization rate, reduced addition of common fertilizers, and improved nitrogen activity; the fertilizer can activate original nutrients in soil, ensure full absorption and utilization of crops, promote increase of crop yield, improve stress resistance of crops, and effectively improve soil. The fertilizer has good adaptability, and is suitable for most crops and soil with good compatibility, and various fertilizers can be added.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a black soybean fertilizer. Background technique [0002] At present, people generally use inorganic fertilizers for fertilization, but long-term use of inorganic fertilizers will cause soil compaction, short fertility time, poor absorption rate of plants, and serious impact on the living environment of plants, resulting in a large reduction in production. The total output of black soybeans will no longer be achieved by expanding the area, but mainly by increasing the yield per unit area. Therefore, scientific fertilization of black soybeans is very important. The special fertilizer for black soybeans produced can meet the nutritional needs of each period in the growth cycle. , greatly increased the yield of black beans, is a high-efficiency fertilizer. Contents of the invention [0003] In view of the above problems, the technical problem to be solved in the present invention is to...
