摘要
根据田间试验观测结果，分析了夏玉米叶片气孔导度与环境因素之间的关系，应用多元非线性回归分析技术建立了气孔阻力的估算模型；对叶片正反两面不同部位和垂向不同层次上叶片气孔阻力的差异及其日变化过程和季节变化规律进行了分析，又用叶片气孔阻力估算模型导出了冠层阻力的计算模型。
Based on the observations of field experiment and the analysis of relationships among the leaf stomatal conductance and environmental factors,the estimating model of stomatal resistance for summer corn has been established by using the technique of non- linear regression analysis.In addition,the differences in stomatal resistance of different leaves in their vertical direction and the observations of stomatal resistance at the different places on two sides of leaves as well as the diurnal courses and the seasonal variations of stomatal resistance are analysed.Then,the calculation model of canopy resistance is derived by using the estimating model of leaf stomatal resistance.
