摘要
试验采用随机区组设计,以当地主栽品种先玉335作为对照,对14个西北组普通玉米新品种在宁夏引黄灌区大田条件下种植的适应性、丰产性和抗逆性进行比较.结果表明：参试品种均能正常成熟,生育期为128-138 d;产量为933.59-1 232.91 kg/667 m2,其中西北组10产量最高,为1 232.91 kg/667 m2,西北组8最低,为933.59 kg/667 m2.相比对照增产的品种有5个,分别是西北组3、6、10、11和13,增产率分别为1.55%、7.79%、13.21%、3.49%、8.72%,西北组10产量显著高于对照,西北组8产量显著低于对照,其余品种的产量水平与对照相当.
This experiment study the adaptability, yield ability, stress resistance of the fourteen corn varieties through randomized block design with three replications under the field in Ningxia irrigation area. We used local main cultivated variety Xianyu 335 as a control. The results showed that all of the tested corn varieties could normal mature. The rage of growth period was at 128-138 day and their yields were at 933.38-1 231.65 kg/667 m2. The highest yield was the northwest group No.10 at 933.38-1231.65 kg/667 m2 and the lowest was the northwest group No.8 at 933.38 kg/667 m2. There were 5 tested varieties had higher yield than that of control（Xianyu 335） those were northwest group No.3, northwest group No.6, northwest group No.10, northwest group No.11, northwest group No.13 and the increase rate was at 1.55%, 7.79%, 13.21%, 3.49%, 8.72%,respectively. The variance test showed that the yield of northwest group No.10 was significant higher than that of control and the northwest 8 was significant lower than that of control. Others were no significant difference.
