摘　　要：为筛选出适合宁夏引黄灌区滴灌种植的玉米新品种,以天赐19号、宁单19号、正大12号等11个玉米新品种为试材,对其生育期、农艺性状、产量等进行比较分析。结果表明,以天赐19号、宁单19号、正大12号3个玉米品种表现最好,其产量分别为12 363.0 kg/hm^2、12 157.5 kg/hm^2、12 112.5 kg/hm^2,百粒重分别为30.80 g、25.25 g、32.26 g,穗粒数、穗长、秃尖长、出籽率等各项指标较也有明显优势,适合在宁夏引黄灌区进行滴灌种植。To screen suitable maize strains for drip irrigation in Ningxia Yellow River irrigation area, with 11 new maize strains such as ＂Tianci＂ No.19, ＂Ningdan＂ No.19 and ＂Zhengda＂ No.12, etc. as testing materials to analyze their growth duration, agronomic traits and output. The results showed that these 3 strains were the best with output of 12 363.0 kg/hm^2,12 157.5 kg/hm^2 and 12 112.5 kg/hm^2 respectively, and with 100-kernel weight of 30.80 g, 25.25 g and 32.26 g respectively. Meanwhile, the ear kernel number, panicle length, bare tip length and kernel ratio had significant advantages, and the strains were suitable for drip irrigation in Ningxia Yellow River irrigation area.
