Objective/Meaning The aim of this study was to provide a scientific basis for improving the farmers’ participation in organic fertilizer application and promoting the green development of agriculture by deeply analyzing the influencing factors and coupling effects of farmers’ organic fertilizer application behavior.

Methods/Procedures  The Meta-analysis method was used to sort out, integrate and analyze 76 empirical literatures at home and abroad in the database, and the individual, economic and external environmental factors and their coupling effects were explored.

Results/Conclusions The results showed that the factors such as cooperative participation, green cognition, and organic fertilizer subsidies were strongly correlated with the farmers’ behavior of applying organic fertilizer; the factors such as education level and cultivated land area were moderately correlated with the farmers’ behavior of applying organic fertilizer; the factors such as gender and annual household income were weakly correlated with it, while age was not related to it. The results of the coupling effect showed that the synergistic effect of individual and economic factors promoted the young, high-income farmers with a prominent proportion of agricultural income to actively apply organic fertilizer. The synergistic effect of economic and external environmental factors promoted the farmers with high annual household income, large proportion of agricultural income and large scale of cultivated land to be more inclined to apply organic fertilizer under the incentive of cooperative technical guidance, government subsidies and low-cost factors. The synergistic effect of individual and external environmental factors promoted the farmers with a high level of education and focus on agricultural production to be more inclined to apply organic fertilizer driven by the dual drive of professional and technical training of cooperatives and policy dividends.
