Effect of Plastic Film-mulching on the Yield of Maize and Soil Condition

[Objective] The aim was to study the yield and soil condition under different plastic film-mulching models,and provide theoretical basis for dry-land corn planting.[Method] The effects of plastic film-mulching on maize yield and soil moisture,temperature and nutrients were studied in field experiments.[Result] After the treatment of plastic film-mulching,the yield of maize,the contents of soil moisture and temperature were increased,and the contents of soil organic were decreased.[Conclusion] Plastic film-mulching has significantly increased yield effect in dry farming areas.
