中文摘要:
      针对朝阳半干旱区春季十年九旱的实际情况,在秋后玉米地设置了玉米地留茬、留茬覆盖玉米秸秆、翻耕、翻耕后覆盖玉米秸秆和翻耕后覆盖地膜5种不同处理方式,探讨不同处理方式对春播前表层土壤水分的影响。测定结果表明,各处理春播前表层土壤水分含量大小顺序为翻耕后覆膜>翻耕后覆盖秸秆>留茬覆盖秸秆>翻耕无覆盖>留茬无覆盖,其中翻耕覆膜处理土壤含水率为17.03%,比留茬无覆盖处理高4.51%,比翻耕无覆盖处理高2.57%,比留茬覆盖秸秆处理高1.27%,比翻耕覆盖秸秆处理高0.66%。
英文摘要:
      In view of the characteristic of spring drought occurring in nine years in a decade in Chaoyang semi-arid region, five different treatments on corn stubble after autumn, including stubble remaining without covering, stubble covered with straw, tillage without covering, tillage plus straw covering and tillage plus film covering, are designed to study the effect of each treatment on surface soil moisture before spring sowing.The results indicate that before spring sowing, the amount of soil moisture of surface layer in different treatments is in the order of tillage plus film covering > tillage plus straw covering > stubble covered with straw> tillage without covering> stubble remaining without covering, and the soil water content of tillage plus film covering is 17.03%, being 4.51, 2.57, 1.27 and 0.66 percentage points higher than stubble remaining, tillage without covering, stubble plus straw covering and tillage plus straw covering respectively.
