生物可降解膜覆盖机插种植技术是将生物可降解地膜与水稻机插技术相结合，实现覆膜和插秧一体化作业的技术。覆膜机插种植能够促进水稻生长，增加水稻植株干物质积累和氮素积累量，提高水稻氮肥利用率和产量；从生态效益上看，覆膜机插种植能够显著降低稻田甲烷排放量，抑制稻田杂草的生长，显著减少杂草群落的种类和密度；从生产效益上看，覆膜机插种植能够减少水稻生长耗水量，降低生产成本，提高生产效益，利用生物可降解膜替代塑料薄膜还降低了水稻覆膜生产中对环境的污染，为水稻绿色提质增效生产提供了新的途径。

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.
