不同环境下温室黄瓜叶片蒸腾速率的研究

INVESTIGATION ON TRANSPIRATION RATE OF GREENHOUSE CUCUMBER LEAVES UNDER DIFFERENT ENVIRONMENTAL CONDITIONS

为了研究环境对温室黄瓜叶片蒸腾速率的影响,以P-M方程为基础模拟了温室黄瓜叶片蒸腾速率在不同温度、相对湿度、光照和土壤温度下的响应状况。拟合结果表明:不同温度、相对湿度、光照、土壤温度下蒸腾速率的模拟值与实测值一致性较好,相关系数平方R2分别为0.728、0.667、0.818和0.824。结果表明:该模型对实现设施农业的高产、优质高效和持续发展具有重要的理论意义和实用价值。

To study cucumber leaf transpiration rate in the environment of the greenhouse, the greenhouse cucumber leaf transpiration rate was investigated based on Penman-Monteith method. It showed that the fitted values were in very close agreement with the measured values under different temPerature, relative humidity, light intensity and soil temperature with correlation coefficient square （R2） 0.728, 0.667, and 0.818 and 0.824, respectively. The results show that the model is important to theoretical significance and the practical value for achievement high yield, high quality and efficiency of facility agriculture and the sustainable development.
