摘　　要：为了探讨黑龙江省南部稻区不同水稻品种干物质积累与产量性状的相互关系,选用了该稻区不同时期主栽的6个品种为试验材料,通过田间小区对比试验进行研究,结果表明:不同水稻品种干物质积累总的趋势是前期低、后期高、中期次之;不同水稻品种抽穗前、抽穗后干物质积累量比例不同,抽穗后干物质积累量明显高于抽穗前干物质积累量;干物质积累量由高到低的品种为‘松粳9号’、‘松粳3号’、‘松粳2号’、‘松粳6号’、‘五优稻1号’、‘藤系138’;产量由高到低的品种为‘松粳9号’、‘松粳3号’、‘松粳6号’、‘松粳2号’、‘五优稻1号’、‘藤系138’;拔节至齐穗期和齐穗至成熟期干物质积累量与产量呈显著正相关;抽穗前干物质积累量与每穗粒数、千粒重呈极显著正相关;抽穗后干物质积累量与产量呈显著正相关;总干物质积累量与产量呈极显著正相关;成穗率与产量呈极显著正相关,结实率与产量呈显著正相关。合理提高拔节至成熟期干物质积累量有利于提高本稻区水稻产量。In order to discuss the relationship between dry matter accumulation in different rice varieties and yield character in southern rice region of Heilongjiang Province, 6 rice varieties of different main cultivated stages in this rice planting area were taken as test materials, and the research was carried out by plot experiment. The results indicated that the general trend of dry matter accumulation of different rice varieties was low in early stage, high in late stage, and middle stage took the second place; dry matter accumulation proportion of different rice varieties was different between before heading and after heading, after heading was significantly higher than before heading. The dry matter accumulation from high to low was as follows： ＇ Songgeng 9＇, ＇ Songgeng 3＇, ＇ Songgeng 2＇, ＇ Songgeng 6＇, ＇ Wuyoudao 1＇, ＇Tengxi138＇. The yield from high to low was as follows： ＇Songgeng 9＇, ＇Songgeng 3＇, ＇Songgeng 6＇, ＇Songgeng 2＇, ＇Wuyoudaol＇, ＇Tengxi138＇. Dry matter accumulation from jointing to heading stage and from heading to maturity presented significant positive correlation with yield. Dry matter accumulation before heading presented extremely significant positive correlation with grain number per panicle and 1000 grain weight. Dry matter accumulation after heading presented significant positive correlation with yield. Total dry matter accumulation presented extremely significant positive correlation with yield. Percentage of earbearing tiller presented extremely significant positive correlation with yield, maturing rate presented significant positive correlation with yield. In conclusion, reasonably increasing dry matter accumulation from jointing to maturity is beneficial to improvingthe yield in this rice planting area.
