| 摘 要： | 利用时域反射仪，对不同灌水次数下土壤含水量的变化进行了研究，分析了不同灌水定额下的土壤含水量随深度变化的特征。结果表明：土壤含水量变化的深度一般在0-100cm内，尤其0～60cm土层变化尤为激烈，在100～180cm范围内各处理土壤水分变化不明显，按枸杞土壤水分运移规律将0～180cm土层进行划分，土壤湿度垂直分布分...

| Abstract: | Through the Time Domain Reflectometry,the soil water change under different irrigation times condition is studied and the change characteristic of soil water along with the depth under different irrigation quota condition is analyzed in this paper.The results show that the depth,in which the soil water content changes,is generally within the range of 0~100 cm,especially intensely in the depth of 0~60 cm.The soil water content change is not obvious in the depth of 100~180 cm.According to the soil water movem... |
