| 摘 要： | 在温室内研究了香蕉树蒸腾量和小气候的关系，用5种方法计算了温室内的参考作物腾发量，用20 cm蒸发皿测定温室内的水面蒸发力，并和测定的香蕉树蒸腾量进行对比。试验结果显示香蕉树蒸腾量和蒸发皿水面蒸发量的回归系数(R2)最高，为0.94，而和5种公式计算的参考作物腾发量的回归系数为0.47～0.60，以蒸发皿水面蒸发量计算温室内的作物蒸腾量要优于以参考作物腾发量计算作物蒸腾量的方法。温室内香蕉树的蒸腾量和20 cm蒸发皿蒸发量线性相关，可以此计算温室内作物的蒸腾量。 |

| Abstract: | An experiment was conducted in a greenhouse to study the relationship between evapotranspiration of banana plants(ET) and climatic factors. Reference evaportranspiration(ET0) inside the greenhouse was calculated using five popular methods. Water evaporation(E) inside the greenhouse was also measured using a 20 cm diameter pan. Results showed that, the determination coefficient(R2) of 0.94 between ET and E was higher than that between ET and ET0 computed using the five methods, which ranged from 0.47 to 0.60. E was linearly related to ET and recommended to estimated crop ET inside a greenhouse. |
