Biological compound fertilizer

Abstract

The invention discloses a biological compound fertilizer. The biological compound fertilizer is prepared from, by weight, 2-4 parts of a microbial agent, 30-40 parts of a monosodium glutamate concentrated waste liquid, 30-40 parts of puffed chicken manure, 20-30 parts of straw, 10-20 parts of fruit residues, 10-15 parts of ammonium bicarbonate, 10-15 parts of diammonium phosphate, 15-20 parts of potassium chloride, 5-10 parts of zinc sulfate, 10-15 parts of ferrous sulfate, 50-60 parts of grass carbon and 20-30 parts of pine needle soil; the microbial agent is prepared from, by weight, 2 partsof EM bacteria, 0.5 part of aspergillus oryzae, 0.5 part of bacillus amyloliquefaciens, 0.5 part of streptomyces jingyangensis and 1 part of nitrogen-fixing bacteria. The biological compound fertilizer has the advantages that the preparation process is simple, secondary utilization of various waste resources is achieved, various microbial effects are combined, the environment is protected, the energy is saved, the fertilizer effect is lasting, the pollution to the environment is small, the soil quality cannot be destroyed, requirements for nutrient elements required for crop growth are met, and the promotion effect on plant growth is positive.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a biological compound fertilizer. Background technique [0002] During agricultural planting, farmers will use chemical fertilizers to provide the crops with the required nutrients to ensure the yield. However, due to the long-term application of large amounts of inorganic fertilizers and high-concentration chemical fertilizers on the land, the trace elements in the soil have decreased, and the soil fertility maintenance effect is poor. The overall quality of soil has declined. The research report of the Chinese Academy of Engineering on the National Soil Environmental Protection and Pollution Prevention Strategy Consulting Project shows that the contribution rate of soil to agricultural production in my country is about 50% to 60%, which is 10% lower than that of 40 years ago and at least lower than that of Western countries. 10 to 20 percent lower.
