饱和持水量测定
measurement of saturation moisture capacity
匕aohe ehishuiliang eeding饱和持水t测定(measurement of satu-ration moisture eaPaeity)土壤农业水文特性测定项目之一，是测定土壤孔隙完全充满水时的l几壤湿度。饱和持水t所占容积等于土壤总孔隙度，可用来鉴定土壤水分饱和程度和总孔隙度。 测定方法是浸水饱和法。即在欲测地段上，用容重环刀取原状土，取土方法与测定卜壤容重时取_L相同(见土壤容l测定)。把装有未遭破坏土样的环刀称重后，使其有孔底一端(内垫滤纸)朝下，放在盛水的平底磁盘中或充满水的砂层上，使盘内水面与环刀上缘保持一样高，切勿使水面淹没环刀，以免影响空气自土壤孔隙排出，使水不能充满孔隙。经过一定时间后(砂土4一8小时，粘土8一12小时)迅速取出，用盒盖托住称重。然后再放入盘中，继续使水充满孔隙，直至前后两次重量无显著差异为止。为了计算环刀中土体的干土重，必须在同一土层上，另取土样，用称重烘干法测其湿度。用下式计算饱和持水量(占干土重的百分数): 环刀中上样吸水饱和*、、、。_后的含水量吧刊’寸小里一环万币王释的不干甭入川U.式中上样干土重(克)=环刀中的湿土重(克)xl()0100十上样湿度的百分数 此外，通过下式也可计算饱和持水量(占干土重的百分数):饱和持水量二总孔隙度 容重火10()%式中总孔隙度二1一宣重比重(林家栋)
