Microbial phosphate fertilizer and application thereof

Abstract

The invention relates to an agricultural fertilizer, in particular to a microbial phosphate fertilizer and application thereof. The microbial phosphate fertilizer is prepared from, by weight, 50%-60% of carriers adsorbed with strains, 30%-40% of monoammonium phosphate and 10% of calcium superphosphate; the strains adsorbed by the carriers are any three of bacillus subtilis, nitrogen-fixing bacteria, nodule bacteria and silicate bacteria and are adsorbed to the carriers separately, and then the carriers are mixed according to the mass fraction of 1:1:1, wherein each gram of the microbial phosphate fertilizer contains 1.0*10<8> to 1.2*10<8> bacterial cells. By means of the microbial phosphate fertilizer, root systems of crops can grow in a developed and healthy mode, yield increasing can be achieved, and meanwhile the microbial phosphate fertilizer is also an indispensable fertilizer for green ecology and green organic foods.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a microbial phosphate fertilizer and its application. Background technique [0002] In order to ensure the demand for increasing grain production, growers apply excessive amounts of phosphorus fertilizers and inorganic nutrients, resulting in too much residue of ineffective fertilizers in the soil, resulting in serious excess of heavy metals. Phosphate ions in phosphate fertilizers combine with cations such as calcium and magnesium in the soil to form intolerant phosphates. A large number of harmful substances and pesticide residues control the growth of nutrients, water absorption, and poor growth of plant roots, resulting in reduced crop production and serious quality decline. , not only wasting phosphate fertilizer but also destroying the soil aggregate structure, resulting in soil compaction, excessive heavy metals, leading to osteoporosis of human body, seriously affecting human...

Phosphate ions in phosphate fertilizers combine with cations such as calcium and magnesium in the soil to form intolerant phosphates. A large number of harmful substances and pesticide residues control the growth of nutrients, water absorption, and poor growth of plant roots, resulting in reduced crop production and serious quality decline. , which not only wastes phosphate fertilizer but also destroys the soil aggregate structure, resulting in soil compaction and excessive heavy metals, leading to osteoporosis of the human body and seriously affecting human health.
