摘要
应用气象学原理推导了不同纬度、不同栽植行向、不同树形的苹果园光能截获率的数学模型，给出在保证树冠基部外围日照时间大于２５％总日照时间的条件下，生长季中充分截获光能的最佳树形、行距、冠高、冠径的优化组合方案．实例分析表明，计算结果与专家经验基本一致．本研究为果园合理栽植，充分利用光能，合理整形修剪提供理论依据与参考方案．
The meteorological theories were used to establish the mathematical model of the light interception of apple trees at different latitudes, in different row orientation, with three tree form.(spindle, cone, and cylinder). The optimum schemes were given for selecting tree forms, row spacings. tree heights and canopy diameters, under the light interception more than 2.5%. The analysis of the example has shown that the computing results agreed with expertise and production practice. The reference plans were given for rational growing of apple orchard. This investigation will be instrumental to abundant light interception and suitable pruning.
