Method for removing peculiar smell of captive sheep house in winter

Abstract

The invention discloses a method for removing peculiar smell of a captive sheep house in winter, and belongs to the technical field of sheep breeding methods. The method specifically comprises the steps that quick lime is applied to the ground and rice husks are laid before sheep are introduced into a sheep house, then a sheep flock is introduced on the second to third days, beneficial microbial liquid is sprayed once in the morning of the day when the sheep flock is introduced, then zymophyte is sprayed once again every 1-2 days, and spraying is continuously conducted twice; and calcium superphosphate is applied once every 7-10 days, the process is repeated once every 15-20 days until the sheep flock is slaughtered, and all the rice husks on the ground of the sheep house are shoveled after the sheep flock is slaughtered. The method can effectively remove the peculiar smell in the sheep house, and particularly has a remarkable removal effect on ammonia nitrogen and hydrogen sulfide; the rice husks do not need to be turned over in the whole sheep flock breeding period and only need to be cleaned once after the sheep flock is slaughtered, so that the breeding labor cost can be greatly reduced; and in the whole breeding process, the sheep house does not need to be washed with water, so that the breeding water consumption is reduced, and zero emission is achieved in the whole process.

Description

technical field [0001] The invention relates to the technical field of breeding methods for sheep, in particular to a method for removing peculiar smell in sheep houses raised in winter. Background technique: [0002] Large-scale and intensive production has become the inevitable development trend of my country's raw sheep production. my country's sheep farming industry has developed rapidly in recent years and its scale has continued to expand. This mode of production improves the production management level, labor productivity and economic benefits of sheep farms, but also causes excessive concentrated discharge of manure and waste water from sheep farms. It puts a lot of pressure on the environment. If it is not treated properly, it will seriously pollute the environment and water sources, and also affect its normal production. [0003] At present, large-scale farmers have introduced the slatted floor model into sheep breeding, and sheep manure enters the cesspit under th...

Problems solved by technology

[0006] The present invention aims at the serious foul gas pollution of sheep sheds in the existing slatted floor breeding mode, the large amount of water used for flushing pens and the production of a large amount of excrement; the need for a large amount of manpower to be invested in the fermentation bed breeding mode due to the need for regular flipping, At the same time, it will also require a large initial investment and other problems. A method for removing odors from sheep houses in winter is invented. This method has an obvious effect of removing odors, does not need to be washed with water, and requires a small investment to achieve zero emissions.
