Agricultural pollution-free microbial improving agent for saline-alkali land

Abstract

The invention relates to an agricultural pollution-free microbial improving agent for saline-alkali land, belonging to an agricultural pollution-free product and capable of improving saline-alkali land and increasing crop yield. The agricultural pollution-free microbial improving agent for saline-alkali land comprises liquid bacteria and solid material, wherein the liquid bacteria comprise 50-70 parts of Bacillus subtilis, 5-15 parts of photosynthetic bacteria, 5-15 parts of yield-increasing bacteria, 5-15 parts of lactic acid bacteria, 5 parts of actinomycetes and 5 parts of leftover from bone meal plant; and the solid materials comprise 50-70 parts of lignite powder, 10-30 parts of leftover waste residue from sulfuric acid production, 10 parts of lower chimney soot from an electric power plant, 10 parts of whit clay, 2 parts of matrine and 3 parts of tobacco stems. The agricultural pollution-free microbial improving agent is prepared by the following steps of: pumping the liquid bacteria to a stirring tank according to a ratio, mixing and stirring to obtain composite bacterial liquid, pulverizing the solid materials by a pulverizer, screening with a 100-mesh sieve, sterilizing, delivering the composite bacterial liquid and the sterilized solid materials to a granulator for granulating, drying, cooling and screening, and checking and bagging finally.

Description

Technical field: [0001] The invention is an agricultural green microorganism saline-alkali land improver, which belongs to the field of agricultural chemical fertilizers. technical background: [0002] According to the pH value of large-scale saline-alkali land in Northeast China, most of them exceed 8 or above. Farmers use chemical fertilizers and synthetic drugs to improve treatment, which is costly and ineffective, and the pollution is serious. Invention content: [0003] The object of the present invention is to provide a green microbial saline-alkali soil improver for agriculture, which is a novel and special-effect microbial saline-alkali soil improver composed of Bacillus subtilis, photosynthetic bacteria, production-increasing bacteria, lactic acid bacteria, etc. as core materials. [0004] Above-mentioned purpose realizes through following technical scheme: [0005] The composition of a green microbial saline-alkali soil improver for agriculture comprises: [00...
