【摘要】 利用2023年黑龙江省玉米种植农户问卷的调研数据，分析农户兼业对其化肥减量施用行为的影响。结果表明，农户兼业会显著抑制化肥减量施用行为，农机社会化服务的调节作用可有效缓解农户兼业对化肥减量施用的负向影响。随着务工距离的增加，在本县内务工的农户，兼业程度对化肥减量施用行为的负向影响最低，县外市内次之，跨市务工负向影响最高。更多还原

【Abstract】 Based on the survey data of maize farmers in Heilongjiang Province in 2023, this paper analyzes the impact of farmers’ part-time employment on their chemical fertilizer reduction and application behavior. The results showed that farmers’ part-time employment significantly inhibited the reduction of chemical fertilizer application. The moderating effect of agricultural machinery socialization service on farmers’ part-time employment positively affected the reduction and application of chemical fertilizers. With the increase of working distance, the degree of part-time employment had the lowest negative impact on the reduction and application of chemical fertilizers in the rural households working in the county, followed by the cities outside the county, and the highest negative impact on the farmers working across cities.更多还原
