| Cultivated land is the basis of agricultural production and development,the agricultural economy and even the whole national economic growth have a major impact.In recent years,China's faster economic growth at the same time,also spent a lot of cultivated land into non-agricultural purposes,the second and the third industry will occupy more arable land year by year.Cultivated land situation situation of serious not only reflect on the reduction in the number of cultivated land,cultivated land quality also nots allow to ignore.Released at the end of 2014,the ministry of agriculture and the ministry of land and resources and cultivated land quality grade in China is gazette and released on the national farmland quality don't investigation and evaluation of the main data results announcement,report,according to the evaluation of first to third accounts for only 27.3%of the total cultivated land,cultivated land and cultivated land such as four to ten is about 72.7%.In addition to the problems of arable land in quantity and quality,the present situation of the rural ageing is faced with farming now.The aging situation of our country is becoming more and more serious,as of the end of 2013,the proportion of people 65 and older in China has reached 9.7%,mainly young and middle-aged labor transfer from countryside to city,makes the rural population aging degree is more serious,mainly engaged in agricultural production labor also shows a tendency of aging population.Of rural ageing labor force will have significant influence on our country's economy and society,especially affects the food security of our country.There are a lot of scholars for aging and the problem of cultivated land quality to do a lot of research,but few have the aging of the population status quo that is associated with cultivated land quality.In this article,therefore,our country agricultural labor force aging population growing and loss of cultivated land quality under the background of reality,on the basis of questionnaire investigation and research,from the choice of the small-scale peasant household the farmyard manure and fertilizer perspective,build the influence of age on farmers fertilizer use behavior mechanism analysis framework.Based on the economics perspective,and through the physical effect,employment effect and the effect of path dependence theory,this paper agricultural labor force aging may affect fertilization behavior intrinsic mechanism,and further use of hilly mountain area in jiangxi province data of theoretical analysis to make empirical test.For our country in aging under the background of how to guide farmers scientific fertilization to improve cultivated land quality put forward the corresponding policy recommendations.To ask questions,analyze and solve problems,on the basis of research on this article specific description of content:the first chapter is the introduction part,mainly is to made clear in this article to the background of the research problem,purpose,significance,research content,and according to the specific content in this paper,the technical route,at the same time inform this article possible innovation and deficiency.Second chapter for literature review part,mainly for ageing this subject studies the influence factors of the mainstream,fertilizer,and summarizes the influence factors of farmyard manure application,found the study of aging more than from the choice of land use efficiency and crop planting,more research on the influence factors of farmyard manure application from the Angle of the property security and stability,the factors affecting both of farmyard manure and chemical fertilizer research,are not systematically analyzed from the perspective of age.This article is on the basis of summarizing the predecessors' research,systematically analyzes the effects of aging for fertilizer selection.The third chapter is theoretical basis and research design section of this article,in order to avoid the conceptual confusion,to involve defining the concept of this paper.Then based on the economics perspective,put forward the agricultural labor force aging may produce physical effect,employment effect and the effect of path dependence,and respectively analyze the three effect on farmers will impact before choosing a fertilizer,and put forward the concrete analysis according to the fact that three of superposition effect,finally is briefly introduced in this paper mainly adopts the econometric model.The fourth chapter for the introduction of the study area and the research of regional data descriptive statistical analysis,including the age of the study area as well as the chemical fertilizer,farm manure application.The fifth chapter is the empirical analysis section,on the basis of the above theoretical analysis,according to the specific condition of fengcheng and suichuan county in jiangxi province,the agricultural labor force aging on fanners fertilizer choice behavior differences of empirical analysis,through the Probit model to the ageing to examine whether farmers use of farmyard manure,using Tobit model to examine the influence of aging on the number of farmers use of farmyard manure,found that aging can significantly increase the size of the application of probability and fertilization.Indicates that the employment effect of aging and the positive effects of path dependence corresponding is greater than the physical effects of inhibition.Again through the Tobit model to examine the influence of aging on the number of peasant household chemical fertilizers,the results show that the aging has not significant influence on the peasant household behavior of chemical fertilizers,illustrate the physical effects of aging and the positive effects of path dependence corresponl 6 part for policy recommendations,mainly is aims at the research conclusion of this article,combining the actual situation of the study area,has certain feasibility policy Suggestions are put forward... |
