| 摘 要： | 本文在田间实测基础上,根据泡桐树冠的几何学特征和辐射在植冠中传输的理论,模拟出不同天气条件下、不同农桐间作田内辐照度的时间、空间分布与树木阴影的移动规律,以及它们对小麦产量的影响。得出农桐间作的最佳模式依间作年期而异,以辐照分布与农林综合效益确定最佳树行距,间作3年以内可为10m,第4—5年为20m,间作6年以后应为40m。

| Abstract: | Based on field observations and following the geometric properties of the canopy of paulownia and principle of polar radiation transfer inside the canopy,a variety of patterns are simulated of solar irradiance distribution in fields with crop-paulownia intercropping of various structures under clear and overcast skies,and the shift of the tree shade is investigated.Results show that under the condition of the paulownia lined in the S-N direction with a 5m specing between trees the optimal structure of the intercropping is formed on the basis of the growth of the tree row spacing from 10 to 40m as a function of the continued operation.Simulations also indicate that the highest yields and hence economic benefits are gained after a 6-year intercropping with the row spacing of 40m. |
