Study On The Mechanism And Application Of The Biogas Slurry

With the application of fertilizer, insecticide and industrializion modern agriculture gains high prosperity at the same time , the environment has been polluted, and people's health has been destroyed we are faced with ardous task to develop efficient, lower polluted organic manure and organic pesticide . This research was put forward to study the component, property, efficacy of the biogas slurry considering the environment protection, and the development oforganic agriculture, first, this research make sure the formative mechanism of the biogas slurry through studying its anaerobic fermentation , second , we study the composition of the biogas slurry , third , we make sure the ingredient which can act as pesticide through a lot of experiments finally , we preliminarily put forward the directions for producing organic pesticide .The research shows that the kinds of the ingredients of the biogas slurry contains more than 100 . More than 20 component of these ingredients can act as insecticide. A lot of experiments show that NH4 ion is the main factor which can kill pest. At the same time, according to experiments' results, we put forward the djrections for producing the organic insecticide by means of this research, the biogas slurry can be more efficiently applied.
