| 摘 要： | 早中熟杂交晚籼稻组合岳优9113,具有分蘖力强,有效穗多,株型较矮,抗倒伏能力强等特点。各产量构成因素中,有效穗、每穗粒数和千粒重与产量呈极显著的正相关,而栽插基本苗数和秧龄期长短与产量有着紧密的关系;根据这些关系,提出了保证密度、控制秧龄等栽培技术措施。 |

| Abstract: | There are some obvious characteristics in late hybrid rice of Yueyou 9113,such as strong tillering ability,high available ears,short plant and strong resistance to lodging,etc.The analysis on relationship between yield and each yield composition factors showed that correlation between available ear,solid grains per ear,1000-grain weight and yield is extremely remarkable;the correlations between of the number of basic seedling,seedling age and yields are all close remarkable.Measures ensuring proper seedlings per area and controlling seedling age are proposed according to these relations. |
| Keywords: | Yueyou 9113 Correlation Yield Yield composition |
