摘要
为了解地表覆盖物不同情况下不同层次土壤水分的差异,采集渭南塬地的耕地与荒草地的土壤样本,采用烘干法获得土壤水分含量,运用Surfer 8.0软件对土壤样本的水分曲线进行绘制研究,以期为改善土壤含水量,提高作物单位面积产量提供依据。结果表明:渭南市塬地农业用地与荒草地土壤水分整体表现为2m以上土壤水分变化幅度较大,2～5m变化幅度较小;2011年10月由于受到降水影响,土壤水分含量整体偏高。
In order to find out the difference of soil moisture at different mulches and different levels,collecting cultivated land and wasteland soil samples in Weinan plateau,the soil water content was determined using drying method,and soil moisture curve was draw using surfer 8.0 software,aiming to provide basis for improving soil moisture and yield per unit area.The results showed that soil moisture changed greatly more than 2 min agricultural land and wasteland soil of Weinan plateau,2～5 m varied less;soil moisture content was high in 2011 October because of precipitation.
