摘    要: 本文从水稻栽培学角度提出了高产群体质量这一新的理论问题。重点论述了水稻抽穗后物质生产量、群体总颖花量、粒叶比、有效及高效LAI、平均茎鞘重、颖花根活量以及有效分蘖率等与高产形成的关系,分别分析了它们在群体质量上的意义,并在有些方面初步指明了作为高产群体质量指标的数量范围。文章还阐述了高产群体质量优化控制的基本程序。

关 键 词:水稻  群体质量  优化控制

Abstract:In this paper, a new theoretical point about population quality of high yield was proposed from the aspect of rice cultivation science, The relations of dry matter production after beading , total spikelet number of population, grain-leaf area ratio, effective and efficient leaf area index,single stem and sheath weight, spikelet-root activity and effective tillering percentage with high yield formation were mainly discussed. The significance of those indexes to the population quality was analised respectively. The quantitative range regarded as target for the population quality was also pointed out primarily in some aspects. At the end of the paper, the primary programme of optimizing control to the population quality of high yield was even more expounded.
Keywords:Rice  Population quality  Optimizing control
