摘要: |
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。 |

Exposition on Genotypes Classification and Relationship Between Quality and Quantity of Crop Source |

Abstract: |
The way of increasing crop yield has been evolved from increasing quantity and bOth quality and quantity to improving quality of source. In order to further raise the yield, a clear and overall understanding of importance of source quality should be en-hanced, photosynthetic rate, higher photosynthetic rate sustained phase and photosynsis adaptbility to enviroment. As a result of genotypes' diversities on quality and quantity of source, it is necessary to select those varieties with highly coordinated property between quality and quantity of source based on the classification of different genotypes sources in terms of quallty and quantity. |
