Abstract

The invention relates to the field of fertilizers, particularly a straw corrosion promoting microbial inoculant-coated biological organic fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 35-56 parts of inorganic fertilizer, 20-40 parts of organic fertilizer, 1-6 parts of humic acid, 4-16 parts of filler, 5-10 parts of polysaccharide assistant and a right amount of corrosion promoting microbial inoculant. By adding the corrosion promoting microbial inoculant, every gram of biological organic fertilizer contains at least 1.1*10<10> cfu of corrosion promoting microbial strain. The granular biological fertilizer is prepared by proper fermentation and processing. The biological organic fertilizer can degrade crop straw residues in the last season. The biological fertilizer obviously increases the yield of the field crops, obviously lowers the morbidity, and enhances the organic matter content in the soil.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biological fertilizer coated with a straw decay-promoting bacterial agent and a preparation method thereof. Background technique [0002] China's crop straw resources are very rich and rank first in the world, with 600 million tons of crop straw produced every year. Corn, wheat and rice straw are the three major crop straw resources in my country. Northeast China and North China are the main grain producing areas in my country, with corn production accounting for about one-third of the country's total and wheat production accounting for about one-fourth of the country's total. In these areas, the multiple cropping index is high, and a large amount of biomass resources (straw) cannot be effectively returned to the field for utilization. Among them, 31.5% of the straw is used as cooking energy in rural areas, and 25% of the straw is burned on the farmland. According to the research o...
