通过７个晚籼品种的通径分析和６０个稳定株系材料在光照不已受遮荫与互有遮荫状态下的两种取样分析，证明稳重是影响单株生产力的最主要因素，而稳重又决定于源、库、流三能力的大小及三者关系的协调。阐明了水稻丰产性的选择拟在一定穗数的基础上，主攻穗重的提高，并注重源、库、流结构的改善，培育具有源足、库大、流强基础结构和多产、快运、满存产量形成机制的高产品种。
Through the path analysis of seven late indica cultivars and the analysis of two samplings of 60 stable lines under unshaven and shaded conditions, it was demonstrated that the most important factor affecting plant productivity was stable, while the stable Also decided by the source, library, flow capacity of the three and the coordination of the three relations. It is clarified that the choice of high yield rice should be based on a certain number of spikes, the main focus to improve the spike weight, and pay attention to the source, library, flow structure improvement, cultivate a source foot, reservoir large, strong flow infrastructure and prolific , Full of high-yielding species formation mechanism.
