摘要
棉花生产中棉铃的重量及其纤维品质存在时空上的差异，这是客观事实。抓好优质铃期的生产管理是提高棉花生产效益的关键途径。本文提出了一套定量分析优质铃群体结构的方法，其分析结果与实际生产管理情况基本相符。与试验设计和模拟分析方法不同，本文的分析从棉花的成铃规律入手，以田间调查数据资料为基本依据，运用模拟分析与优化设计方法相结合的方式实现产量构成及棉铃分布的设计。
It is true that there is temporal and spatial difference for weight and fibre quality of cotton bolls. The key way of raising benefit lies in paying a special attention to the stage of high quality boll forming in field management. The quantitative method,analysing the population structure of the high quality bolls, was suggested. the result was in accord with the actual situation. Out of the ways of experiment design or simulation model analysis, combining optimization method with simulation analysis, the method was proposed on the basis of the boll forming pattern and field inspection. Also, the temporal and spatial optimization model,analysing cotton yield and boll distribution, was proposed.
