基于Meta分析的农户有机肥施用行为影响因素研究

目的 有机肥施用对实现中国农业绿色发展、缓解生态环境压力至关重要，厘清农户有机肥施用行为的影响因素可为农业绿色生产行为等相关政策的制定提供参考依据。方法 文章通过荟萃中国农户有机肥施用行为影响因素的相关实证文献，首次运用Meta分析方法评估了已有研究结论的综合效应量并明确相关影响因素的作用方向和强度。结果 性别、家庭人口数量、家庭年收入、是否接受过技术培训及政府补贴对农户有机肥施用行为有正向促进作用，而土壤肥力对农户施用有机肥行为的影响为负作用。结论 性别、是否接受过技术培训及政府补贴与农户有机肥施用行为存在强相关性关系；土壤肥力为中相关性影响因素，家庭人口数量为弱相关性影响因素；年龄、农户受教育年限、耕地块数、是否饲养家禽的影响较为微弱，仅属于可忽略相关性影响因素。可忽略相关性影响因素数量较多，说明目前围绕农户有机肥施用行为影响因素的实证研究尚未溯及根本，依然存在较大的研究空间。

RESEARCH ON INFLUENCING FACTORS OF ORGANIC FERTILIZER APPLICATION BEHAVIOR OF FARMERS BASED ON META ANALYSIS

The application of organic fertilizer is essential to realizing the green development of China''s agriculture and alleviating the pressure on the ecological environment. Clarifying the influencing factors of farmers'' organic fertilizer application behavior can provide reference for the formulation of related policies such as agricultural green production behavior. Based on a collection of relevant empirical literature on the factors affecting the behavior of organic fertilizer application by Chinese farmers, this article used Meta analysis for the first time to evaluate the comprehensive effect size of the existing research conclusions and clarify the direction and intensity of related influencing factors.The results showed that gender, family population, annual family income, technical training, and government subsidies had a positive effect on farmers'' organic fertilizer application behavior, while soil fertility had a negative effect on farmers'' organic fertilizer application behavior. In summary, there is a strong correlation between famers'' gender, whether or not they have received technical training, government subsidies, and farmers'' organic fertilizer application behavior.Soil fertility is a medium correlation factor, and the family population is a weak correlation factor.Farmers'' age, education, the number of cultivated land and whether raise poultry are relatively weak, which are only negligible relevant factors. There are a large number of negligible correlation factors, indicating that the current empirical research on the influencing factors of farmers'' organic fertilizer application behavior has not been traced to the root, and there is still a long way to go.
