Microbial fertilizer for promoting plant growth

Abstract

The invention discloses a microbial fertilizer for promoting plant growth. The microbial fertilizer is prepared from the following raw materials in parts by weight: 45-55 parts of urea, 30-40 parts of monoammonium phosphate, 1-3 parts of copper sulfate, 1.3-2.8 parts of ferrous sulfate, 1.1-2.4 parts of zinc oxide, 3-7 parts of calcium sulfate, 35-45 parts of wheat bran, 65-75 parts of pig manure, 35-45 parts of maize straw, 5-15 parts of bentonite, 0.5-2.5 parts of bacillus amyloliquefaciens, 0.5-2.5 parts of bacillus subtilis, 0.5-2.5 parts of colloid bacillus, 45-55 parts of potash fertilizer and 5-15 parts of organic acid. The microbial fertilizer for promoting plant growth disclosed by the invention is a powdery bottom applying type fertilizer; the fertilizing time is at the initial stage of planting of the plant; the invention aims to supply the nutrition required by the plant growth, promote the plant growth, increase the setting percentage and achieve the functions of preventing and controlling insect diseases and overcoming soil acidification, hardening and continuous cropping obstacle of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer for promoting plant growth. Background technique [0002] At present, the world is facing severe problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be incr...

Problems solved by technology

This shows that it is limited to increase crop yields only by increasing the application of chemical fertilizers in large quantities, not to mention a series of problems such as environmental pollution.
