从源的数量、质量角度分析作物增产的途径后指出，作物增产是沿着由源的数量增加向着数量、质量并重和以质量改善为主的方向发展。为进一步提高产量，现阶段应加强对源质量重要性的全面认识。光合速率值、光合速率高值持续期和光合对环境适应力等可作为衡量源质量的生理指标。鉴于作物基因型在源的数量、质量生理特性方面表现出的多样性，则开展不同基因型源数量、质量类型分类，选配源数量、质量高度协调的品种是非常必要的。
From the perspective of the quantity and quality of the source, it points out that the crop yield increase follows the direction of increasing the quantity of the source, increasing the quantity of the source and improving the quality of the crop. In order to further increase the output, a comprehensive understanding of the importance of source quality should be strengthened at this stage. Photosynthetic rate, photosynthetic rate of high duration and photosynthesis of the environment adaptability can be used as a measure of the quality of the physiological indicators. In view of the diversity of crop genotypes in terms of the number of sources and the quality and physiological characteristics, it is necessary to carry out varieties with different genotypes, classification of quality types, quantity of matching sources and high quality coordination.
