近年来,为使水稻产量有大的突破,育种工作者已从生理、生态、形态等方面提出各种各样理想型的育种目标。如有从生理上要求提高品种单叶光合效率,以解决“源”的问题;有认为通过增大叶面积或通过理想株、叶型来提高群体净光合率;有从形态上通过穗、粒的合理结构来扩大“库”容等。总之最后要实现扩大“库”容为高产创造条
In recent years, in order to make a big breakthrough in rice yield, breeding workers have put forward various ideal types of breeding objectives in terms of physiology, ecology and morphology. If the physiological requirements to improve the single leaf photosynthetic efficiency in order to solve the “source” of the problem; that by increasing the leaf area or through the ideal strain, leaf type to improve the net photosynthetic rate; there are morphologically by the ear, grain The rational structure to expand the “library” capacity and so on. In short, to achieve the ultimate goal of expanding the “library” capacity to create a high yield
