所谓最大生产力是指在良好生态条件下,植株及其群体结构处于最佳状态时可能获得的产量。显而易见,这种生产力实际上就是生物产量的理论上限,它将唯一地取决于树体截获的光质、光量以及植株光合作用的效率等。根据各地测得的光能数据和作物的特征,可推定其理论上限,此值与现实生产力比较则可评定该地区自然资源的发挥程度。这项工作的意义在于揭示了进一步挖掘生产潜力的可能性,并促使人们为使产量达到这一水平而进行栽培技术和各种自然要素最优组合的研究。
The so-called maximum productivity is under good ecological conditions, plant and its population structure in the best possible yield. Obviously, this productivity is actually the theoretical limit of biological production, it will only depend on the tree light intercepted light, light and plant photosynthesis efficiency and so on. Based on the measured light energy data and the crop characteristics, the theoretical upper limit can be inferred. Compared with the actual productivity, this value can be used to assess the extent of natural resources in the region. The significance of this work lies in revealing the possibility of further digging up the potential of production and of promoting a study of the optimal combination of cultivation techniques and various natural elements to achieve this level of production.
