摘 要: 在沙质碳酸盐草甸土壤上,设置常量化肥、半量秸秆还田+常量化肥、全量秸秆还田+常量化肥三个处理,研究了秸秆还田对玉米生长发育及产量的影响。结果表明,与常量化肥相比,半量秸秆还田处理的植株抗倒伏能力增强,叶面积指数提高,叶绿素含量增加,并且显著提高了产量;而全量秸秆还田处理的各项指标与对照基本相近。 On the carbonate meadow soil contains sand, 3 trial treaments such as routine chemical fertilizer, 50% straws return to field plus routine chemical fertilizer, 100% straws return to field plus routine chemical fertilizer were designed to study the effects of straws return to field on growth, development and yield of maize. The results showed that compared to the routine chemical fertilizer, 50% straws return to field could strengthen the resistance of lodging, advanced LAI and chlorophyll contents, increased the yield of maize. There were insignificant difference between 100% straws return to field and the routine chemical fertilizer.
