作物超高产栽培与株型育种的光合作用基础——以水稻为例

Photosynthetic Base of Super High Yield Planting and Plant-type Breeding of Crop: Taking Rice as an Example

粮食安全问题是中国乃至世界未来面临的重要问题。提高作物的光合作用对解决粮食安全保障具有重要意义。作物叶片利用光能的能力受外界环境的影响,同时群体对小环境的影响反过来又影响叶片的光合作用。本文以水稻为例从栽培和株型育种两个方面讨论了优化群体结构、实现作物超高产的途径。

Food supply safety is an important issue for China even for the world in the future. Improving photosynthesis of crops is of great significance for ensuring food supply safety. Environment conditions affect the capability of light utility of crop leaf, whereas, the effect of crop colony on micrometeorology will influence photosynthesis of leaf. In this paper, taking rice as an example, we discussed ways to optimizing colony structure, realizing super high yield of crop from two aspects: planting and plant-type breeding.
