Research On Analysis Of Fertilizer Application Redundancy And Farmers' Behavior Motivation In Heilongjiang Province

The process of agricultural modernization cannot be separated from the correct handling of the relationship between the development of "agriculture,rural areas and farmers" and ecological environmental protection in China.Since the rural household contract system solved the problem of lack of incentive in agricultural production,China's rural economy has grown rapidly in more than 40 years.Agricultural production depends on the input of fertilizer,pesticide,machinery and other factors increasingly.At the same time,the agricultural environmental problems have become more serious.As the basic input of agricultural materials,fertilizer has an important influence on grain production.How to deal with the contradictory relationship between environmental pollution and economic development,especially regulate the fertilization behavior of farmers to reduce the damage to the rural environment.These problems are the focus of widespread attention by the government and all sectors of society.Since the 18th National Congress,President Xi Jinping has stressed that "We need mountains of gold and silver as well as clear water and mountains of green." "When ecology prospers,civilization prospers,when ecology declines,civilization declines." These discourses illustrate the relationship between economic development and the environment.We urgently need to develop modern agriculture guided by the concept of green development.The purpose is to promote the coordination of agricultural economic development and ecological protection and build a beautiful China.Heilongjiang Province,as a big agricultural province,is the largest commodity grain production base in China.It is a good representation.In this paper,the redundancy problem of fertilizer application is taken as the research object in Heilongjiang Province.First of all,this paper analyzes the relationship between fertilizer application and agricultural economic growth,and preliminarily determines the facts of excessive fertilizer application in Heilongjiang Province.Furthermore,the redundancy of fertilizer application is calculated through the decomposition of production efficiency,and the qualitative description of excessive fertilizer application is transformed into a quantitative measurement of fertilizer application redundancy.It is concluded that the adjustment of farmers' fertilization behavior has a decisive effect on solving the problem of fertilizer application redundancy through the influencing factors.Finally,the motivation of farmers' fertilization behavior was analyzed to explore the effective ways to solve the redundancy of fertilizer application.This paper follows the logic of "research foundation"?"problem definition"?"problem quantification"?"problem analysis"?"problem solving".In order to analyze the following issues:Whether there is a problem of excessive fertilizer application in Heilongjiang Province?If so,what is the degree of fertilizer redundancy?What factors affect fertilizer application redundancy?How to effectively reduce fertilizer application redundancy through key influencing factors?This paper focuses on the core problem of fertilizer application redundancy on the basis of the close combination of theory and reality.The influencing factors of fertilizer application redundancy are discussed through the definition and quantitative analysis.The redundancy of fertilizer application was improved by standardizing the fertilization behavior of farmers.The research mainly includes the following aspects:Firstly,research basis.The concepts of agricultural non-point source pollution,agricultural production efficiency,fertilizer application redundancy and farmers' fertilization behavior are defined.It elaborates the theory of economic growth,the theory of farmers'behavior,the theory of externality and the theory of cost-benefit in details.What's more,the logical mechanism frameworks are sorted out in this paper,which provides a good logical basis for empirical analysis.The practical problems of fertilizer application are further analyzed,based on the current situation and related factors of fertilizer application in Heilongjiang Province.The purpose is to fully grasp the status and characteristics of fertilizer application and provide effective support for further research in Heilongjiang province.Secondly,problem definition:preliminary determination of excessive fertilizer application.This part analyzes the "causality-delay" relationship between fertilizer application and agricultural economic growth.It makes economic judgments on the excessive application of fertilizers and realizes the scientific definition of excessive application of chemical fertilizers.Environmental Kuznets curve was used to test the logical relationship between fertilizer application amount and agricultural economic growth.Vector autoregressive model was used to explore the driving effect of fertilizer application and agricultural economic growth,and the impact effect and cumulative contribution degree were analyzed.The above research proves the objective fact of excessive application of fertilizer from the perspective of economics.Thirdly,problem quantification:redundancy measurement of fertilizer application.On the basis of proving the excessive use of fertilizers,it is necessary to scientifically quantify the excessive use and specific redundancy.This part takes the agricultural production efficiency decomposition as the entry point and calculates the agricultural production efficiency from the time and the space.On this basis,we measure the redundancy of fertilizer application from the perspective of provincial and farmers,judge whether there anre internal consistency and continuity between them,and how to solve the problem of fertilizer redundancy from the perspective of farmers.Fourthly,problem analysis:analysis of factors affecting fertilizer application redundancy.The solution of fertilizer application redundancy needs to identify key influencing factors.The problem of chemical fertilizer application redundancy is effectively solved through the intervention and adjustment of its influencing factors.On the basis of descriptive statistics,reliability and validity test,the influencing factors of fertilizer application redundancy were analyzed.It paves the way for exploring the solution of fertilizer redundancy from the perspective of farmers' fertilizer behavior motivation.Fifthly,problem solved:Implementation of fertilizer application redundancy.Based on the scientific definition of excessive fertilizer use and the calculation of its redundancy,further actions are needed to solve the problem.This part analyzes the factors that influence the redundancy of fertilizer application.The results show that optimizing farmers' fertilization behavior is the main direction to solve the problem of excessive fertilizer application,and it is also the fundamental way to solve the existing problems.The structural equation model is used to analyze the micro motivation of farmers' fertilization behavior.The interaction between farmers' fertilization cognition,fertilization willingness,fertilization behavior,policy cognition and soil testing formula fertilization demand were discussed from multiple perspectives.This paper analyzes the internal logical relationship between these dimensions from single relationship to mixed relationship,and makes a comprehensive discussion on farmers'fertilization behavior.It provides the basis for the countermeasures and suggestions for the rational application of fertilizer in Heilongjiang Province.
