摘　　要：以夏播玉米郑单958为材料,试验探讨了麦秸还田免耕与麦秸不还田免耕两种处理对夏播玉米土壤养分动态变化规律和产量差异等,结果显示,麦秸还田免耕处理土壤养分含量比麦秸不还田处理的土壤养分含量高,对夏玉米生长有利、增产效果显著,平均单产增加1079.10 kg/hm2,增产12.09%,单穗重增加7.667 g,在夏玉米生产上应大力推广麦秸还田免耕栽培技术。With summer sowing corn ZhengDan958 does test material, and explored soil nutrient changing trends about wheat straw return fields and wheat straw not return field two disposes, yield difference etc. The results show that the wheat straw return soil exempt plowing disposal,s soil nutrient content levels higher than wheat straw not return to field disposal ,and avail corn growth ,and increase yield effect prominence. The average increase yield 1079.10 kg/hm2,increase yield rate 12.09%, single ear increase weight 7.667g. In the corn production, it was important the extension wheat straw return soil cultivation techniques.
