| 摘 要： | 以超高产春小麦品种克丰4号为试材，以新克旱9号、东农7742、克涝3号为对照品种，综合考察其独特的产量的结构及其干物质动态积累规律。试验结果统计分析表明：超高产品种克丰4号较其它三个品种具有明显的生物学特征特性，单株小麦的生物产量和粒重相对较低，但单位面积上群体的生物产量和粒重分别提高16.7%和48.2%。尤其以杆强和耐密成为具有当今高产产量潜力的主要因素。为今后东北春小麦超级种的组合配制、后代选择及高效栽培提供理论依据。

| Abstract: | The KefengNo.4 with super high yielding was used as experimental material and Kehan No.9, Dongnong No.7742, Kelao No3 were as Check, the yield component and character of dry matter dynamic accumulation were viewed. The results showed that the KefengNo.4 yield was 16.7and 48.2 percent higher than that of other three varieties in yield, due to Kefeng No.4 with resistance lodging and close planting; this study would be proof for super variety development, making crosses generation selection culture in the future. |
