To clarify the impact of different fertilization trusteeship methods on the level of chemical fertilizer application, based on the survey data of 1 511 maize growers in 12 provinces across the country, such as agricultural production trusteeship and fertilizer input, multivariate treatment effect model was used to empirically analyze the effects and mechanisms of the “operation system” and the “contract system” trusteeship on the level of chemical fertilizer application. The results show that: 1) Compared with the non-trusteeship of fertilization, both the “operation system” and the “contract system” trusteeship can significantly reduce the level of chemical fertilizer application, and the chemical fertilizer reduction effect of the “contract system” trusteeship is more significant, and this conclusion is still valid after the robustness test. 2) Both the “operation system” and the “contract system” trusteeship are effective in reducing the level of fertilizer application by reducing the number of fertilizations. 3) From the perspective of the heterogeneity of labor, land, information and knowledge, compared with the “operation system”, the “contract system” trusteeship can significantly reduce the level of fertilizer application of farmers, and the elderly farmers, small scale farmers, farmers with low information level and farmers participating in the training are more likely to reduce the level of chemical fertilizer application through the “contract system” trusteeship. Based on the research results, the following policy suggestions are put forward: Promoting the precision of agricultural production trusteeship services, promoting the fertilization trusteeship method by classification, empowering farmers to improve their capacity through differentiated training, and strengthening the trusteeship incentive mechanism and effect monitoring.
