以水稻新品种松粳20和松08378为材料 ，探讨了其在黑龙江省第一积温区适宜的高产优质群体构成指标。结果表明，松粳20和松08378均以24丛/m2、5苗/丛为最佳配置，可获得较高产量；产量与株距呈显著负相关关系，与基本苗数相关不显著；不同株距和基本苗数处理对水稻穗部性状和产量构成因素有较大影响。

Using Songjing 20 and Song 08378 as materials, its high yield and fine quality construction were discussed in this paper. The results showed that Songjing 20 and Song 08378 would get high yield when planted with 24 point/m2 and 5 seedlings / point. There was a significant negative correlation between yield and plant spacing. Plant spacing and the number of seedlings had greater effects on the panicle traits and yield components
