我们根据近几年水稻光合生产试验实测资料,分析了汕优63群体光能利用的特征,以及不同群体的光能利用率与转换效率,进而阐明该组合的光合生产潜力,试图为该组合高产栽培与最大地发挥它的增产潜力提供科学依据。 (一)群体光能利用的特征 水稻群体光能利用率的大小,决定于该品种(组合)群体单位面积上接收每卡辐射能所能产生的干物质数量。其计算方法如下:光能利用率(Eu)
According to the measured data of rice photosynthetic production in recent years, we analyzed the characteristics of light energy utilization of Shanyou 63 population, and the light energy utilization efficiency and conversion efficiency of different groups, and then clarified the potential of photosynthetic production in this group, Provide the scientific basis for cultivating and maximizing its yield-increasing potential. (I) Characteristics of Light Energy Utilization The light utilization efficiency of rice population depends on the amount of dry matter that can be generated per unit of radiant energy per unit area of the variety (combination) population. The calculation method is as follows: Light energy utilization (Eu)
