| 摘 要： | 模拟东北寒地旱作地域的气候、降水、土壤等条件,对坡度为0°、4°、8°、12°的耕地进行秸秆深施,研究其蓄水效果及其土壤水分变化规律.结果表明,秸秆深施后在垂直方向上,深度越接近秸秆深施处土壤含水量越大;在水平方向上,距离秸秆深施处越近土壤含水量越大,反之越小;降水72 h后,在0～20 cm土层中的土壤含水量与对照地...

| Abstract: | This study simulated the climate,rainfall and the soil conditions in northeast region,and studied the effect of soil water storage and its variation law in the sloping field(The slope was 0°,4°,8°and 12°) . The results showed that,in vertical direction,the closer near the place of straw deep application,the greater the soil water content;in horizontal direction,the smaller distance between the location of straw deep application and the test position,the greater soil water content,the smaller the contrary. After 72 h precipitation,comparing with the contrast land,straw deep application could let the soil water content increase from 0.20% to 6.17% in 0-20 cm deep aera and have a significant difference(P<0.05) . With the field’s slope increasing,the lateral movement of water increased in the soil,the infiltration capacity of water in deep soil reduced,and the location of the largest increment of soil water content shallowed. |
