摘要: 阴山北麓地区常年干旱,天然降雨稀少,农作物生长受到限制,所以对有限降雨的高效利用意义重大。构建地膜垄沟集雨系统,人工降雨后,测定不同降雨处理0~50cm耕层土壤贮水情况,研究其变化规律。结果表明:不同处理垄背土壤贮水量无显著差异,垄沟贮水量表现为覆膜降雨处理显著高于单纯覆膜处理。3.14mm降雨处理土壤入渗蓄墒率最大,且与它2、3、4倍积降雨量0~50mm耕层土壤蓄水量效果无显著差异。

Abstract: Yinshan Mountain region year-round drought and scarcity of natural rainfall,and crop growth is limited,so efficient use of limited rainfall is significant.Construction of film ridge-furrow system,and determination of 0~50cm topsoil water conditions of the different rainfall treatment after artificial rain to study the variation.The results showed that:the back ridge of soil water treatment was no significant difference,but the water storage capacity of furrow of rainfall treatment was significantly higher than those of film processing.Soil moisture storage infiltration rate of 3.14 mm rainfall treat was the highest,and the replenishment effect of 0~50mm topsoil was no significant difference with it 2,3,4 times rainfall.
