Abstract

The invention relates to a method for preparing biological organic fertilizer from cow dung. The organic fertilizer is prepared from the following raw materials in parts by weight: 80 to 160 parts ofcow dung, 15 to 40 parts of rice bran, 20 to 30 parts of silkworm excrement, 45 to 65 parts of sludge, 8 to 18 parts of urea, 0.05 to 0.5 part of fungicide and the like. The preparation method comprises the steps: preparing the raw materials, stacking, adding the fungicide, stirring and fermenting and sieving. The biological organic fertilizer prepared by the method disclosed by the invention hasthe characteristics of having a high biological organic matter content, improving soil, preventing soil hardening, effectively inhibiting harmful bacteria in soil, effectively and quickly promoting crop growth and the like.

Description

technical field [0001] The invention relates to the technical field of biological organic fertilizer, in particular to a method for making biological organic fertilizer by utilizing cow dung. Background technique [0002] The utilization rate of chemical fertilizers in my country is not high, and the utilization rate of nitrogen fertilizer in the current season is only 35%. According to the Food and Agriculture Organization of the United Nations, China's fertilizer use increased by 61% from 1980 to 2002, while grain production only increased by 31%. Low fertilizer utilization rate has always been a problem in China's agricultural fertilization. The disadvantages of long-term application of chemical fertilizers are: (1) heavy metals and toxic elements increase; (2) microbial activity decreases, and substances are difficult to transform and degrade; (3) nutrient imbalance, nitrate accumulation; (4) acidification intensifies, The pH changes too much. [0003] The total amoun...
