Description

Acidic solid environment modifier for pig farm and preparation method and application thereof Technical Field The invention relates to the technical field of livestock breeding, in particular to an acidic solid environment modifier for a pig farm, and a preparation method and application thereof. Background Along with the acceleration of the large-scale and intensive process of pig breeding in China, the continuous increase of pork consumption demands promotes the remarkable improvement of industrial economic benefits. However, the problem of centralized treatment of the manure in the high-density cultivation mode is remarkable, the manure is fermented to generate harmful gases such as hydrogen sulfide, ammonia nitrogen, manure stink and the like, and pathogenic microorganisms are added to breed, so that the pigsty environment is deteriorated, the health of pigs is threatened, the complaints of surrounding residents and the ecological pollution risks are also caused, and the sustainable development of the industry is severely restricted. A deodorant for farm in China patent publication No. CN108097032A and a method for improving the production performance of livestock by using the deodorant are disclosed, wherein the deodorant comprises the following components, by mass, 1% -5% of propionic acid, 0.5% -8% of malic acid, 5% -20% of saccharomycetes, 2% -15% of bacillus, 10% -30% of lactic acid bacteria and the balance of water. The composite material contains various strains and chemical components, can quickly eliminate harmful gases in farms, and prolongs the duration after odor elimination. However, the deodorant of the patent depends on microorganisms only, and has unstable deodorizing effect under the action and influence of the microorganisms, and the deodorizing agent inhibits partial bacteria in an acidification environment by organic acid, has low ammonia removal rate, and cannot treat complex odor components such as hydrogen sulfide, skatole and the like. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides an acidic solid environment modifier for a pig farm, a preparation method and application thereof, wherein the acidic solid environment modifier comprises natural mineral components (calcium bentonite and nano titanium dioxide) and natural active extract components (phenyllactic acid, citric acid and plant extract deodorant), is safe and nontoxic, has no drug resistance and no residue when being applied to the environment of the pig farm, is low in cost and stable in performance, is simple to use, can obviously reduce the number of bacteria in the pig farm, reduces the ammonia concentration of the pig farm and the humidity of the environment, and has an important effect on maintaining good culture environment and reducing the morbidity of pigs. The invention is realized by the following technical scheme that on the one hand, the acidic solid environment improver for pig farms is provided, and the raw materials comprise, by mass, 80% -90% of natural minerals, 4% -8% of natural acidic extracts, 4% -8% of natural organic acids, 0.5% -1% of photocatalytic nano materials and 1.5% -3.0% of natural composite essential oil, wherein the sum of the mass percentages of the components is 100%.
