| 摘 要： | 在宁夏中部干旱带同心县下马关镇五里墩村,对引进的12个玉米品种的株高、茎粗、穗位高、穗长、穗粗、行数、行粒数、千粒重、产量等生物学指标进行比较研究,结果表明：强盛12号、长城799、先锋335、郑单14号的生物学性状表现较好,产量在5 250 kg/hm2以上,显著高于其他品种;各玉米品种的光合特性测定结果表明：强盛12号、长城799、先锋335、郑单14号等品种的光合速率、蒸腾速率和气孔导度的日变化均值分别大于18μmol/（m2.s）、4.5 mmol/（m2.s）和165mmol/（m2.s）,表现出较好的光合特性。可见,强盛12号、长城799、先锋335、郑单14号适合在宁夏中部干旱带种植。
