摘    要:选用5个不同类型和熟期的典型水稻品种,设置6个肥力水平,研究水稻穗型构成性状对肥力反应的品种间差异.结果表明,增肥使穗粒数增加主要是因为二次枝梗上着生粒数的增加;二次枝梗上粒数增加又集中在其分布的优势部位.由此提出超高产水稻品种应具有中位、偏上位或上位优势穗型.

关 键 词:水稻,品种,穗型构成性状,肥力反应

Abstract:Five typical,different type and mature date rice varieties in Heilongjiang province was tested in six fertility levels to study on the difference in the response of characters of rice panicle type to fertilrty among the varieties.The results showed that the main increasing reason of rice spikelet number per panicle after increasing fertilizer was that the spikelet number of secondary branch per panilcle increased and that the increase of spikelet number of secondary branch per panicle centralized on the superior part of its distribution.It was suggested that the super-high yield rice variety should be middle part,biasing upper part or upper part superiority panicle type according to the results.
Keywords:rice  variety  character s of panicle type  the response to fertility
