| 摘 要： | 为探索在日光温室条件下黄瓜蒸腾规律，利用大型称重式蒸渗仪对其开展相关研究。研究发现，在试验采用的种植模式下，黄瓜全生育期（105 d）蒸腾量为147.74 mm，其中：苗花期、盛果期和尾果期蒸腾耗水量分别为14.06 、102.85和30.84 mm，日均蒸腾强度为1.41 mm/d，盛果期的蒸腾量占到蒸腾总量的69.6％。各生理指标、气象因子与蒸腾强度的相关性依次为：净辐射>相对湿度>水面蒸发量>叶面积指数>温度。经回归分析，建立了多个日光温室迷你黄瓜蒸腾经验模型，可用以估算蒸腾量。

| Abstract: | A large-scale weighing lysimeter was employed to study cucumber transpiration processes in solar greenhouse in Beijing. Based on the cucumber growing processes, the growing season was divided into three stages: flowering-setting, fruiting and later fruiting with stage transpiration 14.06 mm, 102.85 mm, and 30.84 mm, respectively. The cucumber seasonal transpiration was 147.74 mm and the seasonal average transpiration rate was 1.41 mm/d. The most sensitive factor to transpiration rate was net radiation followed by air relative humidity, pan evaporation, leaf area index (LAI), and air temperature in order. Three empirical models were also proposed for estimation of cucumber transpiration rate in solar greenhouse. |
