对土壤干旱胁迫条件下金沙江干热河谷29个植被恢复树种盆植苗的蒸腾耗水特性进行了研究,结果表明:(1)白天不同幼苗蒸腾耗水量均随干旱时间的延长而持续下降,而且下降的幅度具有明显差异;当水分供给量相同时,高强度蒸腾失水的幼苗在极度干热的天气里更易亦更快地受到干旱的胁迫。

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)
