Abstract

The invention discloses a compound microorganism fertilizer specially used for corns and capable of improving soil and a preparation method thereof. The preparation method comprises the steps of: firstly deodorizing fresh poultry dung and cow dung, then adding sporotrichum thermophile, aspergillus niger, distillers' grains, brown sugar, ground straws, corn meal and potassium dihydrogen phosphate to carry out fermentation twice and then drying the product to obtain a preparation I; then taking soybean meal, wheat bran, calcium meal, bacillus megaterium, bacillus subtilis, lactobacillus, cane sugar and ferrous sulfate to carry out fermentation twice and drying the product to obtain a preparation II; and then mixing the preparation I with the preparation II, then adding bacillus megaterium, bacillus subtilis, aspergillus niger, streptomyces alboniger, terrestrial cyanobacterium, photosynthetic bacteria and dinoflagellate to carry out fermentation and finally adding chemical fertilizers needed by corns, thus obtaining the compound microorganism fertilizer specially used for corns. The prepared product contains surviving beneficial microorganisms and can improve the crumb structure and other indexes of soil and increase the corn yield.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preparing soil-improving compound microbial fertilizer special for corn, and also relates to a product prepared by the method. Background technique [0002] With the vigorous development of the tertiary industry in rural areas, there are more and more farmers in rural areas. While the number of farmers is increasing, the amount of manure raised is also increasing. It contains many nutrients that have not been digested and absorbed, such as crude fiber in ruminant manure, nitrogen in pig and chicken manure, calcium in caged laying hen manure, etc., which have great potential for utilization. If these feces are not treated in a timely and effective manner, they will seriously occupy and pollute the soil and water bodies, produce malodorous gases and cause serious pollution. The traditional manure treatment method is to use manure directly as fertilizer, but comp...
