| 摘 要： | 对杂交水稻组两优培九在不同改良强化栽培条件下的群体形成特性进行了比较分析。结果显示，在改良强化栽培条件下，水稻生育后期的功能叶面积下降缓慢，叶绿素衰减幅度减小，粒叶比增大，群体质量明显改善，显著提高水稻产量。采用SRI核心技术，双本插植与单本插植产量差异不显著；直播可以减少水稻的插植的用工量，还可以获得较高的经济产量。 |

| Abstract: | The populations' characteristics of the superhybrid rice Liangyou pei 9 under different cultivation patterns were studied. Results showed that the chlorophyll contents of flag leaf Under the improving SRI cultivation were higher than under the conventional cultivation after flowering stage, the larger LAI,Spikelet/leaf area and Grain/leaf area than that of conventional cultivation.Under SRI conditions, planting two seedlings per hill has no advantage to single seedling in yield. Direct sowing can get higher yield but less labor intensification under SRI conditions. |
| Keywords: | rice SRI population characteristic direct sow |
