Abstract

The invention discloses an animal excrement and straw bio-organic fertilizer and a preparation method thereof. The fertilizer is prepared from animal manure and urine, straw, a straw decomposition agent and probiotic liquid, wherein the raw materials comprise the following components in parts by weight: 60-70 parts of animal manure and urine, 30-40 parts of straws, 0.2-0.3 part of the straw decomposition agent and 0.1-0.2 part of probiotic liquid. The method comprises the following steps: mixing bacillus licheniformis, lactobacillus casei and saccharomyces cerevisiae to obtain the probiotic liquid, and mixing bacillus subtilis, aspergillus oryzae and candida utilis to obtain the straw decomposition agent; mixing the raw material components to obtain a mixed material, wherein the initial pH value of the material is natural; and carrying out facultative aerobic fermentation for 90-120 days at a temperature higher than 4 DEG C, and ending fermentation when the number of fecal coliform bacteria in the material is less than or equal to 50, so that the bio-organic fertilizer is obtained. Animal manure and urine and straw can be converted into organic fertilizer, crop growth can be promoted by applying the organic fertilizer, and the crop yield can be increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a biological organic fertilizer of animal manure and straw and a preparation method thereof. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, the demand for animal products in the domestic market has continued to increase, which has promoted the rapid development of the animal breeding industry, and a large number of large-scale and industrialized farms and breeding enterprises have grown rapidly. However, animals will produce a large amount of waste such as feces and urine during the growth process. There are a large amount of organic matter in these wastes. Direct discharge of these wastes will cause waste of resources and serious environmental pollution problems. Therefore, how to effectively deal with these wastes and reduce environmental pollution has become a difficu...
