以黑龙江省育成的4个超高产水稻品种东农423、龙稻5、松粳3和松粳9为试验材料，以松粳6为对照，系统研究超高产水稻品种的干物质积累规律，结果表明：不同品种在孕穗期以前干物质积累速率无明显差异，孕穗期到齐穗期干物质积累速率的差异明显加大；不同品种在整个生育过程中干物质积累量不同，差异显著；品种间单位面积干物质积累总量与产量呈显著正相关，相关系数为0.904；生育中、后期干物质积累量与产量均呈显著正相关，相关系数为0.897、0.928，说明高产品种的干物质积累量的优势在生育中、后期。

Regulation of dry matter accumulation were systematic researched on super-high-yield rice variety which use Dongnong-423, Longdao-5, Songjing-3 and Songijng-9 as test material and use Songjing-6 as control, The result indicated that accumulation rate of dry materials showed no significant difference on different varieties before the booting stage, and from booting stage to full heading stage its difference increased noticeably. During the whole growing period, dry matter accumulation of varieties were different and the difference was significant. There were significant positive correlation between dry matter accumulation per unit and yield(correlation=0.904). There were significant positive correlation between dry matter accumulation and yield in the middle and late growth period (correlation = 0.897 and 0.928), it showed that the advantage of dry matter accumulation on high-yield rice variety in the middle and late growth period.
