田间耗水量田间耗水量field water consumptiont ianiian haoshuiljang田间耗水盆(field water eonsumption)在作物整个生育期中，农田消耗的总水量。以毫米或米“/亩计。在水田，田间耗水量为作物需水量(见作物需水t)与渗漏量之和:在旱地，田间耗水量通常看作作物需水量。所以，在灌溉工作中，常以作物的最大蒸散量为耗水量。水田渗漏量包括田面垂直渗漏和田埂旁侧渗漏。在较大面积上，主要是田面垂直渗漏。这部分水不能为作物根系吸收，但保持适宜的渗漏速度，有利于土壤中空气的交换。渗漏量大小与土壤条件、农业措施、地形地势、水文地质条件以及水田分布等有关。水田的田间耗水量测定，一般采用田测法。生产中，为防止过量渗漏和减少无效蒸散，还需对作物需水量和渗漏量分别进行测定。用坑测法(有底测坑)测出需水量(蒸散量)，再用已测田间耗水量减去需水量，即为渗漏量。(丁正熙)
