Problems solved by technology

Nitrohumic acid has higher chemical activity and biological activity than humic acid, which can make the water-insoluble or citric acid-insoluble phosphate in the original soil become water-soluble or citric acid-soluble and be absorbed by crops. Cooperative effect activates trace elements in the soil and is easily absorbed by plants, but the effect of using only nitro humic acid is still poor, and soil compaction may also occur during use, so the existing technology needs further improvement

Abstract

The invention belongs to the technical field of fertilizers, and in particular relates to a composite synergist. The composite synergist comprises the following raw materials in parts by weight; 300 to 500 parts of nitrohumic acid; 10 to 30 parts of a composite microbial powder, 2 to 5 parts of dicyandiamide and 2 to 5 parts of hydroquinone; the composite microbial powder is formed by compoundingtwo or more than two of bacillus subtilis, bacillus licheniformis, phosphate solubilizing bacillus, aspergillus niger and aspergillus flavus, and the mass ratio of every two strains is 1g: (1-1.2) g.The composite synergist is good in effect and capable of preventing soil hardening.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a composite synergist. Background technique [0002] Nitrohumic acid (NHA) is a complex aromatic macromolecular system containing carboxyl, phenolic hydroxyl, nitro and other groups generated by the oxygen decomposition of humic acid. Nitrohumic acid has higher chemical activity and biological activity than humic acid, which can make the water-insoluble or citric acid-insoluble phosphate in the original soil become water-soluble or citric acid-soluble and be absorbed by crops. Cooperative effect activates trace elements in the soil and is easily absorbed by plants, but the effect is still poor when only nitrohumic acid is used, and soil compaction may also occur during use, so the existing technology needs further improvement. Contents of the invention [0003] The object of the present invention is to provide a composite synergist with good effect and capable ...
