采用3因素裂区设计,对3个耐密型品种在3个种植密度和3种行距配置方式下的农艺性状及产量的数量差异进行比较研究。结果表明,密度对3个品种的株高、穗位高、茎粗、群体最大叶面积指数(LAI)、穗数、穗粒数和百粒重的影响达极显著水平,行距配置对产量构成3因素存在显著或极显著影响,多个作用大小不一的农艺性状间的交互作用共同影响决定玉米产量。强盛51与大丰26分别在密度为82500株/hm2和“66.6+33.3”cm宽窄行配置模式下产量最高,大丰26在密度为82500株/hm2采用“50+50”cm等行距种植产量可达15000 kg/hm2以上,确定这3个组合为玉米超高产的最佳配置。
採用3因素裂區設計,對3箇耐密型品種在3箇種植密度和3種行距配置方式下的農藝性狀及產量的數量差異進行比較研究。結果錶明,密度對3箇品種的株高、穗位高、莖粗、群體最大葉麵積指數(LAI)、穗數、穗粒數和百粒重的影響達極顯著水平,行距配置對產量構成3因素存在顯著或極顯著影響,多箇作用大小不一的農藝性狀間的交互作用共同影響決定玉米產量。彊盛51與大豐26分彆在密度為82500株/hm2和“66.6+33.3”cm寬窄行配置模式下產量最高,大豐26在密度為82500株/hm2採用“50+50”cm等行距種植產量可達15000 kg/hm2以上,確定這3箇組閤為玉米超高產的最佳配置。

The plot experiment with three factors split was conducted with three maize varieties, three kinds of planting densities and row spacing. The difference of agronomic traits and yield under different experimental condi-tions were analyzed. The results showed that plant height, height of ear position, stem diameter, maximum leaf area in-dex were significantly influenced by planting density, and the three components of maize yield had significant differ-ence at different planting density and mode, interaction among agronomic traits influenced the maize yield. The yield of Qiangsheng51 and Dafeng26 both were the highest at a density of 82 500 plants per ha in wide-narrow row (66.6+33.3 cm) planting mode, Dafeng26 had the higher yield that more than 15 000 kg/ha at the density of 82 500 plants per ha in equal row(50+50 cm) planting mode.The three combinations were the optimal allocation of super high yield maize on the experimental conditions.
