| 摘 要： | 在3种秸秆覆盖量(CK0kg/hm2、A14000kg/hm2、A28000kg/hm2)条件下,研究了玉米田土壤水分的动态变化,其结果表明:秸秆覆盖处理可以增加土壤水分,主要表现在作物生育前期(7月份以前),以20cm土层内效果明显;秸秆覆盖处理增加土壤水分的效果,覆盖量4000kg/hm2要明显好于8000kg/hm2。 |

| Abstract: | This work had researched the dynamics of soil moisture in maize field under three cultivation treatments:routine cultivation,half covering straw minimum tillage,and whole covering straw minimum tillage.The result showed:the treatment of covering straw could increase soil moisture,mainly in the previous development(before July),and obviously in soil layer of 20cm.The effect of increasing soil moisture treatment under the cover measures 4000kg/Hm2 obviously wants to be good in 8000kg/Hm2. |
