Spatial Differentiation Characteristics And Spatial Influencing Factors Of Farmers’ Adoption Behavior Of Soil Testing And Formula Fertilization Technology In Jiangxi Province

Strengthening the protection of cultivated land and firmly guarding the lifeline of national food security is a top priority for country’s national economy and people’s livelihood.Although the state has successively formulated a series of systems such as the protection of permanent basic farmland and the balance of farmland occupation and compensation,which has effectively curbed the trend of sharp decline in the number of farmlands,the quality of farmland and the effect of ecological protection are not optimistic.Among them,the long-term unreasonable application of chemical fertilizers is one of the main factors that threaten the quality of cultivated land and ecological protection.Soil testing and formula fertilization technology,which effectively connects the links of "measurement,distribution,production,supply and application",is an effective means of scientific fertilization.Mastering the spatial differentiation characteristics and spatial influencing factors of farmers’ soil testing and formula fertilization technology adoption behavior is also an important basis for formulating incentive policies for the promotion and application of soil testing and formula fertilization technology.Using the survey data of 658 farmer households in Jiangxi Province,basing on Spatial Autoregressive Model(SEM)and Geographically Weighted Regression Model(GWR),this study analyzes the spatial differentiation characteristics of farmers’ soil testing and formula fertilization technology adoption behavior.On the other hand,an in-depth analysis of Lianhe Village in Dayu County,using 108 farmer questionnaires and 436 field data,and the binary Probit model,this study explored the spatial influencing factors of farmers’ soil testing and formula fertilization technology adoption behavior at the micro level.The research results show that:(1)On the global scale,whether the field has been tested,whether(farmers)have joined the rural cooperative and the cumulative number of technical trainings are the three most important factors that affect the adoption of soil testing and formula fertilization technology by farmers in Jiangxi Province.(2)At the local scale,the influence of the same influencing factor on whether farmers in different regions adopt soil testing and formula fertilization technology have spatial heterogeneity.(3)At the micro level,the field area,field shape,adoption situation around the field,and the adoption of farmers’ neighbors have a significant positive impact on farmers’ adoption of soil testing and formula technology,while the cultivation distance and fertilizer supply distance showed a significant negative impact on it.
