水稻单位面积产量的形成,取决于源库两类器官的数量及其机能相互协调的结果。而不同源库类型水稻品种(源限制型和库限制型)的最适源库指标亦有差异。现以不同栽插密度为基础,研究源限制型和库限制型品种在不同群体条件下颖花形成与物质生产能力的变化特点及其产量效应,论述品种间群体源库数量指标的适宜界限,为因种栽培和夺取高产提供依据。
The formation of rice yield per unit area depends on the number of the two types of organs in the source and the coordination of their functions. However, there are also differences in the most suitable source indicators of rice varieties (source restriction type and restriction type) of different source types. Based on different transplanting density, this paper studied the characteristics and yield effects of spikelet formation and material productivity under different population conditions in source-restricted and library-restricted cultivars, discussed the appropriate limits of quantitative indicators of source stocks in different groups, For cultivation and obtain high yield to provide the basis.
