田间耗水量
field water consumption

  t 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)
