Abstract: The technology of biodegradable film mulching and mechanical transplanting is a technology that combines biodegradable film mulching with machine-transplanted rice to achieve integrated operation of film mulching and rice mechanical transplanting. The technology could promote the growth of rice, increase dry matter accumulation and nitrogen accumulation in rice plants, improve nitrogen fertilizer utilization and yield of rice. In terms of ecological benefits, it could significantly reduce methane emissions and the species and density of weed communities in rice fields, inhibit the growth of weeds. From the perspective of production efficiency, it could reduce the water consumption of rice growth, reduce production costs, and improve the production efficiency of rice. The use of biodegradable films to replace plastic films reduces the environmental pollution, and provides a new way for green rice production to improve quality and efficiency.

Key words: biodegradable film, mechanical transplanting, rice growth, cost-saving and efficiency-increasing, yield
