| 摘 要： | 以沈甜3号早熟超甜玉米为试材，在沈阳地区做了6个不同播期的试验研究。对产量、产量构成因素、主要农艺性状、品质等进行了比较。结果表明：该品种的适宜播期较长，在所试播期内，晚播对产量和品质的影响不大。随播期延迟增产，统计分析差异不显著；穗长、行数、行粒数变化不大；秃尖在各播期之间差异明显，可能与此期降水量的不均匀分布有关。

| Abstract: | The experiment of seeding time with 6 treatments was conducted in Shenyang based on Shentian No.3, an early mature sweet corn. The comparisons were studied through yield, yield components, main agricultural characteristics and quality. The results indicated Shentian No.3 had a strong adaptability for seeding time which made it have a large range of seeding time. The seeding time had no significant effects on yield, quality, ear length, ear lines, and kernels per line, whereas yield slightly increased with seeding time postponed. The seeding time had a significant effect on length of bald tip likely because of temporally uneven distributed precipitation. |
