Method for reducing ammonia emission of silage

Abstract

The invention discloses a method for reducing ammonia emission of silage, which specifically comprises the following steps: step 1, preparation of the silage: preparing silage straws and a large container, cutting the straws into small sections, loading the chopped silage into the storage container, compacting once when the silage is loaded into 20cm of the container, and drying the silage in the container; covering 10-15 cm of silage on the pressed silage raw materials, then sealing the silage raw materials with a plastic film, and waiting for 15 days; 2, liquid medicine generated by ensiling is sprayed to the position where cow dung and cow urine are accumulated through a spraying can, ammonia emission can be reduced, and the effective time is usually 96 hours or longer. According to the method for reducing ammonia emission of the silage, the raw materials are easy to obtain, and the medicament is convenient to prepare; the medicament is green, safe and harmless; the degradation is very easy in the natural environment. And the effect of reducing ammonia emission is obvious.

Description

technical field [0001] The invention relates to a fast, effective, green and pollution-free method for reducing the ammonia discharge of cow dung in a cowshed, in particular to a method for reducing the ammonia discharge of silage. Background technique [0002] In recent years, due to the continuous expansion of the scale of intensive livestock and poultry farming in my country, the output of fecal waste has increased day by day, and the ammonia (NH 3 ) is to cause water eutrophication, soil acidification and aerosol formation and the formation of greenhouse gases and many other issues have a direct or indirect impact. NH from livestock emissions 3 The least known processes contributing to this are the formation of fine particulate matter in the atmosphere, NH in animal manure 3 The formation and volatilization process is almost instantaneous and begins immediately after excretion in urine and feces. NH 3 Once emitted into the atmosphere, fine particulate matter (PM 2.5...

Problems solved by technology

[0003] Common ammonia removal methods in cowsheds include feeding probiotics, urease inhibitors, applying ferrous sulfate, activated carbon, low-volatile inorganic acids, and ammonia removal methods. The cost is high and the actual promotion is difficult. Taking the use of the urease inhibitor NBPT as an example, the market price of one kilogram of NBPT ranges from 500 yuan, which does not meet the actual production needs. Chemicals such as ferrous sulfate reduce ammonia volatilization, but also cause Potential source of pollution, when cow dung is applied to fields, it can cause environmental problems such as land acidification

Feeding probiotics, urease inhibitors and other methods are slow to take effect, and feeding urease inhibitors has also been proved to have hidden dangers to livestock health and safety
