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

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.
