Abstract

The invention relates to the technical field of organic fertilizer preparation and discloses a cow dung fermentation method. The cow dung fermentation method comprises the following steps: S1: weighing the following components in parts by mass: 2-4 parts of bacillus subtilis, 1-3 parts of bacillus licheniformis, 1-2 parts of penicillium and 1-5 parts of actinomycete, and carrying out activation for 22-26h; S2: placing the bacillus subtilis, the bacillus licheniformis and the penicillium subjected to activation in a first culture medium, carrying out fermentation for 18-20h, and placing the actinomycete subjected to activation in a second culture medium, and carrying out fermentation for 18-20h; S3: mixing respective microbial agents obtained after fermentation in the first culture medium and the second culture medium, taking 70-75 parts of cow dung, 20-25 parts of auxiliary material and 0.4-0.8 part of the microbial agent according to mass portion to form a mixture, and carrying out strip stacking type fermentation on the mixture; S4: when the fermentation temperature reaches 60-70 DEG C, transferring the mixture to a fermentation groove, and carrying out turning throw fermentation on the mixture in the fermentation groove until the moisture content of the mixture is lower than 30 percent. The cow dung fermentation method disclosed by the invention is rapid in temperature rise, high in decomposed degree and relatively short in fermentation period.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a cow dung fermentation method. Background technique [0002] At present, the use of organic fertilizers as fertilizers for crops has become a trend in agricultural production. Compared with chemical fertilizers, organic fertilizers contain more nutrients, which can improve soil and prevent compaction. Improve product quality, increase resistance to diseases and insect pests, and optimize utilization; compared with ordinary farmyard manure, organic fertilizer has no odor, is convenient and uniform to use. Moreover, the addition of beneficial bacteria to organic fertilizers can reduce the occurrence of diseases and the nutrient content is relatively high. [0003] Most of the existing organic fertilizers are made by fermentation of poultry manure such as chicken manure and pig manure. Compared with other poultry manure, cow manure has a higher crude fiber co...
