Abstract

The invention discloses a compound microbial fertilizer and a preparation method and application thereof. The compound microbial fertilizer is prepared from, by weight, 1%-2.5% of bacillus megatherium, 2%-3.5% of salt decomposing bacteria, 0.5%-1% of bacillus subtilis, 0.5%-1% of bacillus licheniformis, 0.5%-1.5% of bacillus amyloliquefaciens, 1%-3.5% of bacillus mucilaginosus, 6%-8% of nitrogen, phosphorus and potassium, 1%-3% of medium trace elements, 10%-25% of amino acid powder, 30%-55% of humic acid and 8%-20% of moisture, wherein the proportion sum of all the components contained in the compound microbial fertilizer is 100%. According to the compound microbial fertilizer, saline-alkali lands can be neutralized, the physicochemical properties of saline-alkali soil and the soil structure can be improved, the permeability can be improved to accelerate salt leaching, the utilization ratio of the medium trace elements can be increased, and the desalting effect is good; meanwhile, nitrogen, phosphorus and potassium and multiple microorganisms are added, the soil fertility is improved, decomposition of matter difficult to decompose is accelerated, soil-borne diseases are inhibited, and successive cropping obstacles are overcome.

Description

technical field [0001] The invention relates to the technical field of microbial application and the field of microbial fertilizer, in particular to a compound microbial fertilizer, its application in soil improvement and its preparation method. Background technique [0002] Soil salinization (soil salinization) refers to the natural geological process in which salt continuously accumulates on the soil surface to form saline soil. Saline soil is formed under certain natural conditions such as climate, topography, land, hydrogeology, etc. In addition, human activities, historical floods, floods, and droughts, changes in river courses, and land use, agriculture, and water conservancy technical measures will also have a major impact on the occurrence and development of soil salinization. The hazards of saline-alkali land are very serious. Due to the accumulation of a large amount of salt in the soil, a series of deterioration of soil physical properties are caused: sticky stru...
