【摘要】 玉米是辽宁省第一大粮食作物，但传统种植模式容易引发土壤退化、秸秆处理不当等问题，现有秸秆还田模式也存在缺陷。为此，研究提出玉米秸秆错位覆盖技术，并在辽宁省调兵山市设置试验，对比该技术与传统全覆盖、裸地模式的效果。结果显示，错位覆盖能提升地温、优化土壤含水率，出苗率达91.00%，产量达785 kg/667 m~2，综合成本较传统全覆盖降低20.00%，可破解“地温—水分—结构”协同难题，为玉米可持续生产提供支撑。更多还原

【Abstract】 Corn is the largest grain crop in Liaoning Province, but the traditional planting mode is prone to problems such as soil degradation and improper straw treatment, and the existing straw returning to the field mode also has flaws. For this reason, this study proposes the corn straw offset mulching technology and conducts experiments in Diaobingshan, Liaoning Province to compare the effects of this technology with the traditional full mulching and bare land mode. The results show that offset mulching can increase ground temperature, optimize soil moisture content, with a germination rate of 91.00%, a yield of 785 kg/667 m~2, and the comprehensive cost was reduced by 20.00% compared with the traditional full mulching. It can solve the problem of the synergy of "ground temperature-moisture-structure" and provide support for sustainable corn production.更多还原
