| 摘 要： | 在旱作条件下研究了不同玉米品种的穗长、穗粗，行粒数，百粒重等产量因素和亩保苗株数、灌浆期土壤含水量等环境因素对产量的影响。结果表明：穗粗对产量有极显著的正相关和正向的直接效应，百粒重和穗长对产量呈微弱的正相关，行粒数对产量有微弱的负相关。土壤含水量与产量有较高的负相关和负向的直接效应，株高、功能叶数、亩保苗与产量有较低的正相关。灌浆期比较抗旱品种是丰禾7号、绥玉7号和丰禾332品系；先玉335表现中度抗旱，龙单13、四单19表现出抗旱性较差。

| Abstract: | The ear length, ear diameter, row grains, 100 grain weight etc of corn were studied in dry codition. The result showed that ear length was significantly positive correlated with yield, 100 grain weight and ear length were lightly positive correlated with yield, and row grains was lightly negative correlated with yield. Soil water content was highly negative related with yield, plant height, leaf number and planting density were lightly negative correlated with yield. The variety relatively resistant to dry in filling period were Fenghe7, Suiyu7 and Fenghe332. Xianyu335 was the mediem one, and Longdan13 and Sidan19 were poor ones. |
