水稻秸秆全量还田模式下小麦高产增效创建示范

摘要

This paper discussed the measures to reach wheat yield of 7 500 kg/hm2 under returning total rice straw to field model,pointed out soil compaction can improve physics and chemistry character of soil and increase the rate of wheat seeds emergence.A high rate of seedling emergence was got under wheat straw returning to field and then the rice.%探索水稻秸秆全量还田技术下实现小麦单产7 500 kg/hm2的措施,指出镇压可有效改善土壤的理化性状,提高小麦的出苗率;不同秸秆还田方式下,以小麦秸秆还田出苗数最高,秸秆不还田次之。
