采用裂区试验设计,以密度为主处理、品种为副处理,密度设7.5万、9.0万、10.5万株/hm2,研究新疆主要玉米品种密植条件下农艺性状及耐密性。结果表明,密度间、品种间、密度与品种互作差异均达极显著水平。空秆率、秃尖长随密度增加而增加,株高、穗位高、穗粗、穗行数随密度变化保持恒定,茎粗、穗长、行粒数、千粒重随密度增加而减小。国外品种的耐密性普遍好于国内品种,耐密丰产型玉米品种在密植条件下空秆率低,株高、穗位高、千粒重等主要农艺性状随密度变化保持恒定。

By split plot design, and density as the main treatment, variety as the assistant treatment. Three density levels were 75 000 plants/ha, 90 000 plants/ha and 105 000 plants/ha. The agriculture character and denseness of maize hybrids in Xinjiang were analyzed. The result showed that density, variety and the intersection of density and variety were significantly variant. Foreign varieties were better than domestic varieties of resistant tightness. The empty stalk rate of the maize variety with dense-resistance and high-yielding was low. Plant height, ear seat, 1 000-grain weight and other major agronomic characters were stagnant with density change.
