为探明行距配置对紧凑型冬小麦品种粒质量的影响，在大田条件下，设置15 cm、20 cm、25 cm 3种行距处理，研究了其对紧凑型冬小麦品种新麦26灌浆特性的影响。结果表明，新麦26的粒质量增加动态、灌浆速率、灌浆持续期和最终粒质量受行距的影响。15 cm 处理的籽粒干物质累积增长量在灌浆前期较低，但后期增加速度较快，至花后31 d 分别比20 cm 处理、25 cm 处理增加1％、5％。籽粒灌浆速率在灌浆前期表现为20 cm 处理＞25 cm 处理＞15 cm 处理，灌浆后期表现为15 cm 处理＞20 cm 处理＞25 cm 处理。相对灌浆速率随行距增大而上升，最大灌浆速率和平均灌浆速率受行距的影响较小。灌浆持续期随行距增大而缩短；最终粒质量和理论粒质量随行距增大而下降，下降幅度分别为4％和8．5％。因此，缩小行距能延长灌浆持续期，提高粒质量。

In order to evaluate the effect of row spacing patterns on grain filling characters of compact winter wheat variety Xinmai 26,a field experiment was carried out with three row spacing patterns:15 cm,20 cm and 25 cm.The results showed that row spacing patterns could influence the dry matter accumulation of gain,gain filling rate,grain filling duration and final grain weight.The gain weight increment were lower and higher during earlier and later grain filling period respectively in 15 cm treatment,which was 1% amd 5% higher than that in 20 cm and 25 cm treatments after flowering 31 d.The grain filling rate of different treatments order was 20 cm>15 cm> 25 cm during early grain filling stage,and 15 cm> 20 cm> 25 cm during later grain filling stage.Increasing row space raised the relative grain filling rate,but cut down the grain filling duration.The maximum and mean grain filling rates were relatively stable.The final and predicted grain weights decreased by 4% and 8·5%,respectively,along with the increase of row space.Therefore,the narrow row space could extend the grain filling duration and increase the grain weight.
