| 摘 要： | 利用离心机测定北京顺义地区典型农田土壤的含水量及其对应负压值,采用van Genuchten(1980)模型进行了土壤水分特征曲线拟合。根据农田土壤物理特性参数测定的数据,比较了不同质地、不同种植条件、不同深度的土壤特征曲线的特征。结果表明,土壤质地及种植条件等对原状土的土壤水分特征曲线有显著影响。

| Abstract: | Soil water content and the corresponding value of tension are obtained using centrifuges and was simulated by vG mode1 of soil samples from Shunyi in Beijing.According to the data tested by the parameters of the field soil physical properties,the characteristic of the soil moisture curve have been compared under the different texture,planting condition and depths.The results show that the soil texture and cultivation conditions have a significant impact on the soil moisture characteristic curve of the undis... |
