Special active organic bacterial fertilizer for rice and preparation method of special active organic bacterial fertilizer

Abstract

The invention discloses special active organic bacterial fertilizer for rice and a preparation method of the special active organic bacterial fertilizer. The special active organic bacterial fertilizer comprises the following raw materials: traditional Chinese medicinal material residues, chicken manure, calcium humate, urea, a microbial fermentation microbial agent, rice husks and rice straw. Thepreparation method comprises the following steps: (1), pulverizing the rice husks, performing high temperature carbonization, performing processing into biochar under the anaerobic conditions, and pulverizing the prepared biochar; (2), mixing the rice straw, the traditional Chinese medicinal material residues and the chicken manure, performing crushing, mixing the crushed materials with the calcium humate and urea so as to obtain a mixture, stacking the mixture, maintaining the temperature at 50-60 DEG C and the water content of 60% or above, performing turning and stacking every 12-18 hours,and determining the total number of turning according to the decomposition degree, wherein when the water content of 15-20% and temperature of 30-40 DEG C are stably obtained in the stack, a decomposed material is obtained for later use; (3), mixing the biochar and the decomposed material, performing drying, spraying the microbial fermentation microbial agent, and performing mixing so as to obtain the special active organic bacterial fertilizer for rice.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a special active organic bacterial fertilizer for rice and a preparation method thereof. Background technique [0002] Rice is an important grain crop in my country, its sown area accounts for about 30% of the sown area of ​​grain crops, and its output is close to half of the total grain output. In the process of rice production, large-scale planting is adopted. At present, the most commonly used method for pest control is pesticide control. However, extensive use of pesticides will inevitably cause pesticide residues. Although there is no short-term effect of eating food containing pesticide residues, pesticides will gradually accumulate in the body after long-term consumption, and when the limit is reached, it will cause disease. Therefore, it is of great significance to take measures to avoid or reduce the use of pesticides from the source. Contents of the...
