| 摘 要： | 采用二裂式裂区设计,对紧凑型、半紧凑型、平展型3种株型玉米品种的密度及产量结构、叶面积系数、干物质重、光合势、净同化率等主要群体质量指标进行了研究.结果表明,紧凑型玉米临奥4号最佳产量水平密度为4000～4800株/667m2,其主要质量指标:最大叶面积系数3.39～4.14,干物质积累量1523.60～1632.00kg/667m2,总光合势16.11万～19.98万m2·d/667m2,平均净同化率为7.39～8.34g/(m2·d).半紧凑型玉米毕玉2406最佳产量水平密度为3200～4000株/667m2,其主要质量指标:最大叶面积系数2.67～3.15,干物质积累量1159.36～1334.80kg/667m2,总光合势16.35万～18.79万m2·d/667m2,平均净同化率为6.68～6.82g/(m2·d).平展型玉米毕单13号最佳产量水平密度为3200～4000株/667m2,其主要质量指标:最大叶面积系数3.81～4.23,干物质积累量1209.60～1390.00株/667m2,总光合势22.68万～24.96万m2·d/667m2,平均净同化率为5.16～5.22g/(m2·d). |
