| 摘 要： | 以高原粳稻区大面积应用的大穗型、穗粒型、多穗型品种为材料,研究不同穗型品种的产量潜力。结果表明,这3种穗型品种均可获得11.00 t/hm2以上的超高产,其主要原因是穗粒协调,形成了较多的颖花数;多穗型品种的颖花数主要靠有效穗贡献,大穗型品种的颖花数主要靠穗粒数贡献,穗粒型品种的颖花数靠有效穗和穗粒数协调贡献;抽穗前期干物质积累量为多穗型品种穗粒型品种大穗型品种,抽穗后期干物质积累量为大穗型品种穗粒型品种多穗型品种。

Analysis on Yield of Different Panicle Types Plateau Japonica Rice |

| Abstract: | The yield potential of different panicle types plateau japonica rice varieties were studied, using multiple panicle varieties, large panicle varieties, medium panicle varieties in large area cultivation as materials. The results indicated that a high yield above 11.00 t/hm2 is achievable for all of them, primarily because of ear-grain coordination, which helps develop more spikelets. The more spikelets of multiple panicle varieties are mainly contributed by effective panicle, those of large panicle varieties mainly contributed by the number of grains per panicle, and those of the medium panicle varieties mainly contributed by the coordination between effective panicle and grains. It was also noted that in terms of the quantity of accumulated dry matter before heading, multiple panicle vari-eties>medium panicle varieties>large panicle varieties, after heading, medium panicle varieties>large panicle varieties>multiple pani-cle varieties. |
