| 摘 要： | 秸秆覆盖可以减少土壤表面水分蒸发,提高水分利用效率.以不覆盖处理为对照,2005年10月至2007年10月在获嘉县农场对冬小麦和夏玉米生育期间进行了秸秆覆盖处理对比观测.结果表明,秸秆覆盖后近地层气象要素发生了改变,覆盖后近地层空气温度升高,水汽压降低,地表土壤温度下降;秸秆覆盖有明显的保墒、蓄水作用,提高了土壤水分利用率;同时秸秆覆盖对提高冬小麦的成穗数,增加冬小麦和玉米的千粒重有明显作用.试验期间,推广田冬小麦增产幅度为8.7%,夏玉米增产幅度为8.9%. |

| Abstract: | The straw stalk cover may reduce the soil surface moisture evaporation,and raise the moisture content use efficiency.By taking the processing without straw stalk cover as comparison,the observational experiments of the straw stalk cover in wheat and corn growing period were conducted from October 2005 to October 2007.The experimental result indicates that,the straw mulching led to changes of meteorological elements near the ground,the air temperature increased,while the vapor pressure near the ground decrea... |
