Microbial organic fertilizer and preparation method thereof

Abstract

The invention relates to a microbial organic fertilizer, belonging to the field of a fertilizer. The microbial organic fertilizer is prepared from the following raw materials in parts by weight: 80-100 parts of crop straws, 35-45 parts of livestock and poultry stools, 0.01-0.03 part of VT-1000 fermented strain, and 0.1-0.3 part of anti-caking agent. A preparation method of the microbial organic fertilizer comprises the following steps: mixing the crop straws, livestock and poultry stools and VT-1000 fermented strain according to the proportion, adding into a fermentation tank, performing primary fermentation and then stack-up fermentation (namely secondary fermentation); mixing and stirring and grinding the biologically fermented materials, introducing vapor into a pelletizer and pelletizing, drying, cooling and screening, so as to obtain primary microbial organic fertilizer particles; and adding the anti-caking agent into the primary microbial organic fertilizer particles and performing enveloping treatment. The microbial organic fertilizer contains a great amount of organic matters and microorganisms, has higher fertilizer utilization ratio during application, can strengthen roots and promote seedlings to accelerate early ripe of the crops, the quality of crops can be improved, the soil structure can be improved, and the sustainable high yield capability of soil can be enhanced.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a microbial organic fertilizer and a preparation method of the microbial organic fertilizer. Background technique [0002] At present, with the rapid development of science and technology, people's living standards are gradually improving, and people's requirements for crop yield and quality are getting higher and higher. Therefore, chemical fertilizers are widely used in agriculture as a fast and efficient agricultural fertilizer. In production, the yield and quality of crops are effectively improved. However, the utilization rate of chemical fertilizers is relatively low, long-term use causes huge waste, and the nutrient elements of chemical fertilizers are single, often used to cause soil erosion and damage the soil structure. Severe soil erosion reduces the grain production capacity of large areas of land. In the early days of the founding of the People's Republic of C...
