摘要/Abstract

摘要： 本文应用以下模型或子模型:(1)有效穗数子模型,(2)每穗粒数子模型,(3)结实率子模型,(4)生育期“水稻钟”模型,(5)群体光合生产(或“源”产量)模型,(6)“库”产量模型,对不同品种或品种类型水稻的穗粒结构在长江流域的气候生态特征和“库”、“源”产量的协调性特征进行了数最分析。分析结果对于评价不同品种或类型的水稻在长江流域的气候适应性,找出限制产量的气候因素,指出增产途径和制定生产对策具有重要价值。最后还利用长江流域水稻气候生态鉴定试验(1985～1986)的有关资料对上述分析结果进行了验证和评价。

Abstract: In this paper, the characteristics of geographical distributions for rice yield components in the Yangtze Valley were described, and also the sinksource relations of different rice varietal types in the concerned region were analysed, based on the following established models or submodels, named, 1) effective panicle number per unit field area, 2) grain number pet" panicle, 3) filled-grain percentage, 4) "rice clock" model for development, 5) "source" yield model, 6) "sink" yield model. The results are of great importance to assessing the climatic suitability of different rice varietal types in the studied region, to finding the climatic constrains on rice yield, to pointing out the way to increase yield and to making decisions in rice managements. The authors finally tested and evaluated the results, using the data taken from the Rice Climatic-Ecological Experiment conducted in the Yangtze Valley between 1985—1986,
