Abstract

The invention discloses a microbial deodorant for a pig farm and a preparation method. The preparation method comprises the steps: (1) crushing straws to obtain crushed straws, carrying out anoxybiotic calcination, and carrying out cooling, so as to obtain biochar; (2) inoculating corresponding liquid culture media with activated bacilli, activated lactic acid bacteria and activated saccharomycetes, carrying out culture so as to separately obtain bacterial solutions, of which the content of each is higher than 109CFU / mL, and carrying out mixing, so as to obtain a compounded bacterial solution;(3) uniformly mixing the biochar with the compounded bacterial solution, carrying out stirring, and carrying out culture; and (4) carrying out solid-liquid separation, and baking solids, thereby obtaining the microbial deodorant for the pig farm. The microbial deodorant for the pig farm, disclosed by the invention, can secrete active substances, promote the growth of beneficial microbes and generate fragrance; organic matters can be fermented to adjust pH and inhibit the growth of harmful bacteria; and enzymes are produced, and thus, the generation of malodorous gases is inhibited. The microbial deodorant is environmentally friendly and efficient and is low in cost and simple and convenient in preparation method.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a microbial deodorant for pig farms and a preparation method. Background technique [0002] At present, with the development of animal husbandry in various regions, intensive farming has emerged in large numbers, and the amount of feces discharged is increasing, and the problem of feces pollution has become increasingly prominent. The texture of pig manure is finer and its composition is more complex, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salt. Due to the characteristics of pig manure with many pathogenic bacteria and serious pathogen hazards, and because the odor produced by pig manure directly affects the health of humans and animals, and also deteriorates the working environment for resource utilization operators to engage in collection and utilization, it is the resource utilization of livestock and poultry manure. ...
