| Abstract: | 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... |
