摘    要:以中粳稻广陵香粳和中籼稻汕优63为材料,采用不同的肥料运筹和插栽密度等措施,研究水稻拔节期茎蘖结构与叶面积指数(LAI)及产量的关系。结果表明:水稻抽穗期适宜的LAI,拔节至抽穗期叶面积生长速率大于N-n期至拔节期,有利于形成高产叶面积动态类型;拔节期茎蘖数结构与拔节期、抽穗期LAI关系密切,拔节期适宜的茎蘖结构有利于抽穗期适宜LAI的形成。

关 键 词:水稻  茎蘖结构  叶面积指数  产量

Abstract:The relationship between tiller structure and LAI and yield formation was studied with mid-season rice indica , cv.shangyou 63 and japonica , cv. Guanglinxiangjing. The main results were as follows: Appropriate LAI at hea- ding stage and higher growth rate of LAI from elongating to heading stage than that of from N-n stage to elongating stage led to forming high-yielding LAI dynamic type. Appropriate number and structure of stems and tillers at N-n and elongating stage had close relationship with LAI of elongating and heading stage.
Keywords:rice  structure of tillers and stems  LAI  yield
