Biological compound fertilizer and preparation method thereof

Abstract

The invention relates to a biological compound fertilizer and a preparation method thereof. The biological compound fertilizer is prepared from, by weight, 10-15 parts of a microbial agent, 5-10 parts of lactobacillus plantarum, 5-10 parts of photosynthetic bacteria, 5-10 parts of yeast, 80-120 parts of straw, 30-50 parts of bagasse, 30-50 parts of peanut hulls, 30-50 parts of soybean meal, 30-50 parts of poultry and livestock manure, 30-50 parts of water, 30-50 parts of a modified carrier, 0.5-1 part of a water retaining agent, 3-6 parts of corn starch, 0.5-3 parts of sodium carboxymethylcellulose, 3-5 parts of alkyl glycoside, 0.5-2 parts of a complex enzyme preparation, 0.5-1 part of citric acid, 5-10 parts of fulvic acid potassium powder, 5-10 parts of ammonium molybdate, 5-10 parts of urea phosphate, 5-10 parts of sodium borate, 3-5 parts of zinc sulfate heptahydrate, 3-5 parts of carboxymethyl chitosan and 3-5 parts of crospolyvinylpyrrolidone. The biological compound fertilizer can enhance the disease resistance and immunity of crops, loosen soil, improve the ecological environment, effectively degrade pesticide residues and macromolecular organic matter, increase the crop yield and improve the crop quality.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a biological compound fertilizer produced by using livestock and poultry manure and straw and a preparation method thereof. Background technique [0002] Chemical fertilizers, mainly containing nitrogen, phosphorus, and potassium elements, supplement the lost nutrients for the soil, thereby increasing the yield of crops. However, with the frequent and single use of chemical fertilizers, it has an adverse impact on the soil environment. The soil lacks sufficient nutrients. Under the condition of organic matter, the soil aggregate structure is difficult to form, and the adhesion between soil particles is weakened, which reduces the water retention capacity of the soil. When the soil cannot retain sufficient moisture, even high-quality fertilizers are not easy to release nutrients under favorable conditions. In order to solve the problems caused by the long-term use...

Problems solved by technology

To improve the environment and develop ecological agriculture, there is an urgent need to improve planting technology, completely change the past practice of relying on a large number of chemical fertilizers and pesticides to increase crop yields and produce high-volume and low-quality products, and strictly limit the use of pesticides and chemical fertilizers
