光合作用是植物营养的基本形式。产量的高低,首先是最紧密地取决于群体植物光合作用的强度和结果,而光合作用又与太阳辐射有极为密切的关系。在研究群体植物的光合作用——生产力之主要因素——的基础上,产生了关于作物群体的最适结构,关于其叶面积的最适增长进程及其工作指标的概念体系。
Photosynthesis is the basic form of plant nutrition. The level of yield, first and foremost, depends most strongly on the intensity and the results of the photosynthesis of the population of plants, and the photosynthesis has a very close relationship with solar radiation. Based on a study of the photosynthesis of plant populations, the main factor of productivity, a conceptual system about the optimum structure of crop populations, the process of optimum growth of their leaf area, and their work targets has been developed.
