Preparation method for high-efficiency organic fertilizer

Abstract

The invention discloses a preparation method for a high-efficiency organic fertilizer. The preparation method comprises the following steps: a, preparing a microbial agent; b, uniformly mixing organicwaste containing a nitrogen element and straw chips under stirring, wherein a mass ratio of the organic waste containing the nitrogen element to the straw chips is 3:1, and controlling the moisture content of the mixed material to be 40%-70%; c, in the mixing and stirring process of the above step b, adding the microbial agent into the material, and performing inoculation, wherein a usage amountof the microbial agent is controlled to be 0.1-0.3% of a mass of the material; d, performing stacking fermentation on the material obtained in the step c; and e, when the temperature in a stack reaches 50 DEG C, performing primary stack turning, after stack turning is completed, performing stacking, after primary stack turning is completed, repeating stack turning once every 3-4 days, wherein thetotal times of stack turning are controlled to 8-10, and in the process, a high temperature of 60-70 DEG C can be maintained for 20 days or more, and ensuring that the moisture content of the final material is 40% or less to form the bio-organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a production method of high-efficiency organic fertilizer. Background technique [0002] In people's daily life and agricultural and industrial production processes, a large amount of organic waste and carbon-containing waste will be produced, such as livestock, poultry, and human excrement, distiller's grains discarded from wineries, bagasse discarded from sugar factories, Including various plant fibers of crop stalks, etc. At present, these materials are not fully utilized, and they are dumped everywhere, seriously affecting the environment and causing environmental pollution. Some of them are directly used as fertilizers for agricultural production. It has not been harmlessly treated before use, and has limited nutrients. More importantly, it also contains a large amount of substances harmful to crops, which brings harm to crops and land. In order t...
