摘    要:[目的]为建立高效的玉米光合生产体系提供参考。[方法]采用紧凑型玉米(先玉335和郑单958)与平展型玉米品种(长城799和通吉100)为材料,通过田间试验,解析紧凑型玉米群体的冠层结构特性,比较不同株型玉米品种的产量。[结果]先玉335和郑单958茎叶夹角表现为:下层叶〉中层叶〉上层叶,长城799和通吉100茎叶夹角表现为:中层叶〉下层叶〉上层叶。紧凑型玉米品种上部茎叶夹角小,群体透光率较好,有利于增加叶面积指数;下部茎叶夹角相对较大,可充分利用光能;生育后期具有较高的叶面积指数和较强的生理活性,能够充分利用生育后期的光能资源,延长灌浆期,从而制造更多的干物质,为高产奠定基础。先玉335的产量最高,为13 716.3 kg/hm^2,紧凑型玉米品种与平展型玉米品种产量之间存在着显著差异。[结论]为探索合理的群体布局及保证玉米高产提供了理论依据。
