| 摘 要： | 通过试验测定苹果园土壤水分特征曲线、饱和导水率、土壤体积质量、有机质等土壤理化指标,分析了陕西省优质苹果园表层土壤的水分特征。结果表明,礼泉土壤的饱和含水量最高,超过0.600 0 m3/m3;洛川最低,为0.473 9 m3/m3。蒲城土壤的凋萎含水量最高,陇县最低。安塞、富平土壤的有效含水量较高,均超过0.250 0 m3/m3;蒲城最低,不到0.150 0 m3/m3。礼泉土壤的饱和导水率超过250 cm/d,入渗能力最强;洛川和韩城则不足15 cm/d。

| Abstract: | By measuring soil water characteristic curves,saturated hydraulic conductivity,bulk density,soil organic matter and other indicators,the topsoil water characteristics of high quality apple orchards in Shaanxi province were studied.The results showed that the saturated water content of Liquan is the highest with more than 0.600 0 m3/m3;Luochuan is lowest with 0.473 9 m3/m3.The wilting point of Pucheng is highest,Longxian fall into the last.The effective water content of Ansai and Fuping are higher,exceeded 0... |
