Problems solved by technology

[0002] At present, the fertilizers used in agriculture are mainly divided into chemical fertilizers and organic fertilizers, but with the improvement of living standards, the cultivation of crops is becoming more and more simple and mechanized. Fertilizers containing one or several nutrient elements needed for the growth of crops, long-term use will easily lead to the destruction of soil structure, reduced production potential, increased metals and toxic elements, reduced microbial activity, difficult conversion and degradation of substances, and nutrient imbalance , nitrate accumulation, acidification intensification, pH changes too much and other problems

Abstract

The invention discloses a preparation method of a biological compound fertilizer. The method comprises the following steps: weighing the following raw materials, in parts by weight: 10-15 parts of a composite biological bacteria preparation, 6-10 parts of modified biochar, 5-10 parts of an amino acid liquid, 20-30 parts of urea, 3-5 parts of ammonium sulfate, 0.5-1.5 parts of calcium phosphate, 5-10 parts of a microelement nutrient solution, and 25-35 parts of glycerol. According to the method provided by the invention, the modified biochar improves soil saturated hydraulic conductivity, can effectively reduce occurrences of surface runoff and soil erosion, the modified biochar can promote decomposition of the urea and the ammonium sulfate, so that the fertilizer can more quickly work; thecomposite biological bacteria preparation comprises a microcapsule outer shell and biological bacteria, after the modified biochar and the composite biological bacteria preparation are mixed, the mixed mixture can provide more habitat for survival of aspergillus niger and rhizobia, and promote the action of the aspergillus niger and the rhizobia on crops.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, in particular to a preparation method of biological compound fertilizers. Background technique [0002] At present, the fertilizers used in agriculture are mainly divided into chemical fertilizers and organic fertilizers, but with the improvement of living standards, the cultivation of crops is becoming more and more simple and mechanized. Fertilizers containing one or several nutrient elements needed for the growth of crops, long-term use will easily lead to the destruction of soil structure, reduced production potential, increased metals and toxic elements, reduced microbial activity, difficult conversion and degradation of substances, and nutrient imbalance , Accumulation of nitrate, intensified acidification, too much pH change and other problems. [0003] Aspergillus niger is an important fermentation industrial strain, and it is the main production strain of xylanase, acid pro...
