Chemical fertilizer for black soybean and preparation method of chemical fertilizer

Abstract

The invention discloses a chemical fertilizer for black soybean and a preparation method of the chemical fertilizer. The chemical fertilizer for the black soybean is prepared from the following constituents in parts by weight: 100-120 parts of cow dung, 30-50 parts of castor cake, 12-16 parts of mushroom dreg, 60-80 parts of rice husk powder, 20-30 parts of algae powder, 8-10 parts of bacteria powder, 30-40 parts of coal gangue, 2-4 parts of amino acid, 40-60 parts of bentonite, 20-30 parts of distillers' grains, 40-50 parts of achnatherum inebrians, and 80-100 parts of water. The chemical fertilizer for the black soybean disclosed by the invention is scientific and reasonable in formula, low in cost, environment-friendly in materials, and free of residue to cause any damage.

Description

technical field [0001] The invention relates to a plant fertilizer, in particular to a black soybean fertilizer and a preparation method thereof. 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. Contents of the invention [0003] The invention provides a black soybean fertilizer and a preparation method thereof. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A black soybean fertilizer comprises the following components in par...
