High microorganism fertilizer and its preparing method

Abstract

The invention relates to a fertilizer and a preparation method thereof, in particular to a fertilizer with high microbe content and the preparation method thereof, which belongs to the technical field of agricultural fertilizer. The preparation method comprises the following steps: 1) melting sugar in water and boiling the obtained solution; 2) adding the following raw materials by proportions: combinations of bean cake, peanut cake, and castor cake by any proportion to ferment the carrier, polysaccharide and sweet water obtained in Step 1, stirring the obtained solution in Step 2 uniformly to carry out a spontaneous fermentation for 3 to 10 days after adding the strain so as to obtain pre-fermented strains; 3) drying and crushing night soils, and adding the pre-fermented strains, phosphorite powder, and microelement mineral powder into the night soils and uniformly stirring the obtained mixtures for fermentation at a temperature of 5 DEG C to 70 DEG C, while at a preferable temperature of 50 DEG C. When the number of live strains reaches 2*10<9> / g, the fermentation can be ended; wherein, the oxygen is required to be pumped at a speed of 0.3-10m<3> / min in the process of fermentation. The fertilizer has particularly obvious curing effects on the plant diseases and preventive effects on the insect pest.

Description

A kind of high microbial fertilizer and preparation method thereof (1) Technical field The invention relates to a fertilizer and a preparation method thereof, which is a fertilizer with high microbial content, referred to as high micro-fertilizer and a preparation method thereof. The invention belongs to the technical field of agricultural fertilizers. (2) Background technology Investigation and research on domestic and foreign agriculture in the 20th century was characterized by the use of chemical fertilizers to increase production by 2-3 times, but it caused soil compaction, severe disease and insect damage, excessive use of pesticides, excessive pesticide residues in agricultural products, food safety problems and environmental protection problems. Research and experiments have proved that: 1. The poor air permeability of soil compaction causes microbial population imbalance between aerobic bacteria and anaerobic bacteria, and the effect of aerobic bacteria on inhibiti...
