用产量结构要素来分析产量的变化原因及其规律是一种直观而又简捷的方法,但产量结构要素一般要在生育末期才能确切获取,因而作动态分析时并不理想。本文以全国杂交稻气象科研协作组的分期播种资料(汕优六号、1981年)在分析干物质积累规律的基础上,对籼型杂交水稻的干物质积累特征进行了分型,并根据气象条件对作物生产力诸要素的影响规律,分析了形成各类生长型的气象原因,试图就如何通过合理布局和播栽期的安排来改变干物质的积累过程,为提高生物学产量提供农业气象依据。
It is an intuitive and simple method to analyze the reason of yield change and its regularity with the elements of production structure. However, the elements of yield structure are usually obtained exactly in the late growth period, so it is not ideal for dynamic analysis. In this paper, the dry matter accumulation characteristics of indica hybrid rice were classified on the basis of the analysis of dry matter accumulation rules based on the staged seeding data (Shanyou No.6, 1981) of the National Hybrid Rice Meteorological Research Collaboration. According to the meteorological Conditions on the productivity of various elements of the law to analyze the formation of various types of growth meteorological reasons, trying to how to change the process of accumulation of dry matter through reasonable layout and sowing date arrangements to improve the yield of biological agricultural meteorological basis .
