摘要
以试验区实测资料为基础，根据泡桐的树形特征和太阳辐射在树冠中的传播特性，建立了晴、昙、阴不同天气条件下各种密度农桐间作田内太阳辐射的分布模式，较好地体现了间作地辐射日变化趋势。并分析了影响辐射分布的因素，为配置合理的间作模式提供依据。
Based on measurements from an experimental area and considering the characteristicshape of and the propagation properties of solar radiatio11 amongst the canopy of paulownia,8model is constructed for solar radiation distribution inside a patch with crop·paulowniaintercropping at a range of densities under such skies as clear,cloudy and overcast.Compared toother analogs,the present model can better imitate the solar radiation pattern daily course in suchfields,with the factors affecting the distribution investigated,thereby providing a basis forpreparing an effective intercropping model。
