Research On The Prevention And Control Of Agricultural Non-point Source Pollution In Zhaozhou County Based On The Fertilization Behavior Of Farmers

With the rapid development of agricultural economy,agricultural output increases year by year.Fertilizer is considered as the main cause of agricultural non-point source pollution,mainly due to soil pollution caused by farmers' unreasonable fertilization methods and residual nutrients brought by a large amount of fertilizer,which are washed by rain and irrigated into water,causing water environment pollution and causing great pressure on agricultural ecological environment.Due to the randomness and wide range of agricultural non-point source pollution,it is very difficult to control the end of agricultural non-point source pollution.As the main body of agricultural non-point pollution production and prevention and control,how to induce farmers to apply fertilizer rationally is of great significance to the effective prevention and control of agricultural non-point pollution based on fertilizer input.The research content is as follows: firstly,the definition of agricultural non-point source pollution and the prevention and control of agricultural non-point source pollution is made,and the literature research method is used to sort out the research of domestic and foreign scholars,and the situation of fertilizer application and farmers' behavior of fertilizer application in zhaozhou county are analyzed through data consulting and field investigation.Then,descriptive analysis was carried out on the status of farmers' fertilization behavior.Finally,chi-square analysis and multiple regression analysis were carried out on the sample data,and the following conclusions were drawn.Relevant countermeasures were proposed according to the conclusions.Through the analysis of the data of the sample farmers,it is concluded that the main factors affecting the fertilization behavior of farmers are the number of plots,whether there is contracted land,whether the non-point source pollution of agriculture is known,whether the technical guidance of fertilization is obtained,the number of family cultivated land,and the main source of income.Among them,farmers with more plots applied more fertilizer,those with contracted land applied more fertilizer than those without contracted land,those with no knowledge of non-point source agricultural pollution applied more fertilizer than those with knowledge of non-point source agricultural pollution,and those with vocational and technical training would reduce the amount of fertilizer applied in agricultural production activities.The more farmland a farmer has,the less fertilizer he can apply.Farmers who take agriculture as a sideline and prefer part-timejobs will increase the amount of fertilizer applied when carrying out agricultural production activities.Finally,Suggestions on prevention and control of non-point source pollution in agriculture were put forward based on the research on farmers' fertilization behavior.To strengthen the work of agricultural extension and actively carry out the work of agricultural technical training;Promote land transfer to achieve appropriate scale operation of cultivated land;Adjusting Fertilizer Application Structure and Implementing Organic Fertilizer as a Substitute for Chemical Fertilizer;We will increase input in agricultural science and technology and popularize the technology of soil testing and fertilization.Learn from the successful prevention and control experience of non-point source pollution;We will strengthen policy implementation and ensure that policies are effectively implemented.
