耕地细碎化对农户化肥减量施用的影响机制
Mechanisms of the influence of land fragmentation on fertilizer application reduction:Based on the moderating effect of outsourcing agricultural production
摘要
Abstract
In order to promote the sustainable development of agriculture and solve the problem of high application of fertilizers in China,according to the current situation of land fragmentation and focusing on the goal of reducing the application of fertilizers,this study explore the regulation mechanism of land fragmentation and outsourcing agricultural production on fertilizer application reduction based on the theory of farmers'behavior.A theoretical framework of"land fragmentation-outsourcing agricultural production-fertilizer application reduction"is constructed,and the 875 corn farmers'research data in the three northeastern provinces are used to test the theoretical framework.The results show that:Land fragmentation inhibits farmers'fertilizer application reduction;outsourcing agricultural production promotes farmers'fertilizer application reduction.It plays a moderating role in the process of land fragmentation affecting fertilizer application and able to weaken the impact of land fragmentation.Fertilizer outsourcing and non-fertilizer outsourcing have this effect;The moderating effect of non-fertilizer outsourcing on different farmers is robust,and the moderating effect of fertilizer outsourcing is more significant for farmers with a higher degree of part-time employment and with transferred land.Based on this,this study puts forward the following recommendations:Improving the land transfer system,encouraging farmers to integrate land and continuous production to improve the degree of land fragmentation;encouraging technological innovation,improving the service level of the service main body,and standardizing the standard of fertilizer application;encouraging farmers to adopt advanced science and technology and improving the efficiency of the production of agricultural inputs.关键词
