| 摘 要： | 对四川9种母质发育的12种土壤的4个重要水分常数研究表明,土壤最大吸湿水为18.2～145.8g/kg,凋萎系数为27.0～200.3g/kg,毛管断裂湿度为232.3～344.2g/kg,田间持水量为369.3～498.7g/kg.各种水分常数与土壤粘粒含量呈极显著正相关,并与其它计算方法的结果吻合性较好。

| Abstract: | Four principal moisture constants of 12 soil groups generated from 9 parental materials in Sichuan wcrc studied. Maximum soil absorbed raoisture capacity, wilting coefficient, breaking capillary water capacity and field moisture capacity ranged from 18.2 to 145.8, 27.0 to 200.3, 232.3 to 344.2 and 369.3 to 498.7 gkg~(-1), respectively. Moisture constants were shown to be in significant posifive correlation with soil clay content and were in fairly good agreement with the results obtained with other estimation methods. |
