Abstract

The invention relates to a dedicated composite bacterial fertilizer for saline-alkali soil and a preparation method of the composite bacterial fertilizer, and belongs to the technical field of composite bacterial fertilizers. The composite bacterial fertilizer is prepared from the following raw materials in percentage by weight: 10-20% of a phosphate-solubilizing potassium-solubilizing composite bacterial inoculant, 40-60% of kitchen waste, and 30-40% of diatomite, wherein the phosphate-solubilizing potassium-solubilizing composite bacterial inoculant is prepared by the following steps: respectively culturing and centrifuging bacillus megatherium, bacillus thuringiensis, pseudomonas fluorescens, bacillus amyloliquefaciens, bacillus mucilaginosus and azotobacter chroococcum, performing freeze drying on the centrifuged bacteria, drying, and performing balanced mix on the dried bacteria; the kitchen waste is prepared by the following steps: sorting the kitchen waste, removing impurities, dehydrating and removing oil from the kitchen waste, then crushing the kitchen waste, adding the composite bacterial inoculant and a mixed enzyme preparation, and at last performing aerobiotic solid state fermentation. The composite bacterial fertilizer is prepared by recycling the wastes such as the kitchen waste and the waste diatomite, so that the saline-alkali soil can be improved fundamentally.

Description

technical field [0001] The invention relates to a special compound bacterial fertilizer for saline-alkali soil and a preparation method of the compound bacterial fertilizer, which belongs to the technical field of compound bacterial fertilizer. Background technique [0002] Soil salinization is a worldwide problem. Saline-alkali soil is a soil type widely distributed on the earth's land, accounting for about 25% of the total land area. China's saline-alkali soil is widely distributed, with a large area and many types, with a total area of ​​about 300 million hm 2 . It is estimated that the saline-alkali soil in the world is 100,000-150,000 hm2 per year. 2 With the rapid growth rate, we are facing great challenges, and the rational use of saline-alkali land resources has become an important issue. With the increasing shortage of land resources in the world, increasing the improvement and utilization of saline-alkali land can effectively alleviate the contradiction between...
