蒸腾
transpiration
zhengteng燕腾(transpi俪on)植物体内水分以气态形式向外散失的过程。燕腾是正常状态下水分近饱和的植株与较干的大气之间的水气梯度造成的水分交换，蒸腾造成植株体水分移动的水势差是植物吸收和输送水分的动力之一。蒸腾能够降低植物体温度，可以使溶于水中的矿物质营养随上升液流分布到植物各部位，以维持正常的生命活动。在相同水分条件下，蒸腾强度反映作物生长势强弱和作物吸收水分、养分能力大小。蒸腾与植物干物质、产量有关。影响蒸腾量大小的有气象条件、土壤、农业措施、植物生长状况，尤其是叶片气孔的开张程度。在自然条件下，准确测定植物蒸腾量是很困难的，群体作物蒸腾量测定更为困难。确定农田作物蒸腾量有两种方法:一种是差值法，即根据农田总耗水量E和株间土壤蒸发量Ep差值来确定。另一种方法是直接测定法，直接测定装置是在种有作物蒸渗计的土面上用覆盖物密封，使其不进行土壤蒸发，这时测出的蒸发量即为作物蒸腾量。11一62(X)便携式光合作用仪可用于测定叶片蒸腾强度 用数学方法计算蒸腾量的方程式为: 液相气相 。必乙一必七c;一C.
