| 摘 要： | 研究表明，滇中盆地和金沙江谷地高产水稻（10．5－15t.hm^-2)的产量形成特点为：（1）产量结构上具有单位面积穗数多和每穗粒数多的优势，在大数体条件下仍保持高的结实率和大穗优势；（2）水稻的生育期长和高原独特的光温条件有利于植株的稳健生长和产量器官的协调发展；（3）光合速率高，干物质积累量大，库源关系协调，这些特点的形成与高原独特的气候生态条件和栽培管理密切相关。 |

| Abstract: | The characteristics of yield formation of high-yield rice with yield of 10.5-15.0t*hm－2 in the middle basin and Jinsha River valley of Yunnan plateau were studied.The yield formation of high-yield rice in those areas was characterized by the following three aspects:(1)more ears per unit area and more grains per ear,higher seed setting rate and bigger ear;(2)full growth and harmonic development of yield organs due to the long growth duration and favorable photo-thermal conditions in those areas;(3)higher rate of photosynthesis,more dry matter accumulation,and harmonic relation between sink and source.The formation of these characteristics is closely related to the u nique climatic ecological environment in the plateau and the rice cultivation and management. |
| Keywords: | middle Yunnan plateau Jinsha River valley rice yield formation |
