地膜覆盖栽培是有效保持寒旱区土壤水热条件、促进作物生产的措施之一。为解决长期覆盖普通地膜造成的土壤地膜残留污染及生物降解地膜破裂，且成本高的问题，通过多年试验研究，从地膜选择、肥料配比、绿色地膜复合覆盖技术、田间管理、地膜回收、秸秆与生物降解地膜还田等方面总结了寒旱区玉米普通地膜与生物降解膜覆盖栽培技术。

Film mulching cultivation is one of the measures for sustaining soil hydrothermal conditions and promoting crop production. To address the issues of biodegradable mulch film rupture and high cost, and residual pollution of long-term plastic film mulching, mulching cultivation technologies using plastic film and biodegradable film in the cold and arid regions were summarized through years of experiments with the following aspects i.e. mulching film selection, fertilizer combination, composite mulching techniqueusing green film, field management, film recycling, an dstraw and biodegradable film returning to land included.
