对进一步强化水稻群体光合生产能力及其调控进行了论述。认为，在保证较高适宜叶面积指数的基础上，进一步优化群体结构和选育具广幅光强适应能力的品种是实现进一步强化水稻群体光合生产能力的关键。同时，在栽培上做到合理密植、提高施肥水平、提高粒／叶比、培育强大根群和加强后期田间管理。 This paper also discussed the ability of further strengthening the photosynthetic production of rice population and its regulation. It is considered that further optimization of population structure and breeding of varieties with wide light intensity adaptability are the keys to further strengthen the photosynthetic production capacity of rice population on the basis of ensuring a high suitable leaf area index. At the same time, cultivation should be done in a close and reasonable manner, fertilization level should be improved, grain / leaf ratio should be improved, strong root groups should be nurtured, and field management should be strengthened later.
