Scale operation of farmland is an important path to promoting green agricultural development.As a special form of farmland scale，whether connected planting can drive farmers to engage in agricultural green production is an important topic worth discussing.This paper analyzes the impact of rice connected planting on agricultural green production by using the tracking data of farmers in Yangshan County，Guangdong Province，from 2017 to 2019，and the results show that connected planting can significantly reduce the use of fertilizers and pesticides，thereby promoting farmer’s green production practices.This finding remains robust after various tests.Second，mechanism analysis reveals that farmers engaged in connected planting achieve green production by increasing the outsourcing of mechanical services and enhancing the degree of contract of these services.Third，heterogeneity analysis indicates that farmers with smaller operational scales and smaller land plots benefit more from connected planting in terms of promoting green agricultural production.Fourth，scenario analysis shows that in contexts where land tenure is clarified and high levels of trust exist within villages，connected planting further strengthens farmers’ green production practices.Therefore，encouraging farmers to carry out connected planting and developing the market for productive agricultural social services can help integrate small farmers into the process of greening agriculture.
