旱地玉米整秸秆不同覆盖形式的增产效应

The Effect of Different Mulching Methods with Whole Maize Straw in Dry Land on Maize Yield

通过对玉米整秸秆不同覆盖形式的大田试验表明 ,玉米整秸秆不同覆盖形式均有不同程度的增产效应 ,其中以秸秆地膜二元单覆盖效果最佳 ,比对照增产 54.5% ,整秆半耕半覆盖增产4 0 8% ,秸秆地膜二元双覆盖增产 36 .0 %

The results of a field experiment of different mulching methods with whole maize straw showed that different mulching methods had different effect on maize yield. The best method in this experiment was the combination of mulching with plastic film and maize straw. The yield of dual mulching was 36 0%～54 5% higher than CK, and the yield of mulching with maize straw only was 40.8% higher than CK.
