地膜覆盖对玉米产量及其土壤状况的影响

[目的]研究旱作农业区垄膜沟种、全膜平作和裸地平作大田玉米产量及其土壤状况特点,为旱作玉米种植提供理论依据。[方法]利用大田试验研究双垄沟种、全膜平作和裸地平作对玉米产量及其农田土壤水分、温度和养分的影响。[结果]地膜覆盖处理后,玉米产量增加,土壤含水量及温度也明显增加,但土壤的有机质含量减少。[结论]在旱作区地膜覆盖玉米具有明显的增产作用。

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.
