中文摘要：
研究比较了甘肃引黄灌区主栽玉米品种沈单16号与引进的10个玉米品种对盐碱地适应性。结果表明,与沈单16比较,敦玉2号增产最为明显,KWS 2564、甘鑫吉祥1号的增产不明显,其他品种都有不同程度的减产。从籽粒变异系数分析,变异系数高的品种受盐分胁迫后的适应性较差。种植敦玉2号土层的离子含量较其他品种的低,种植KWS 2564、甘鑫吉祥1号的土层离子含量也较低。敦玉2号无论是在耐盐碱以及稳产方面均有优势,可作为耐盐碱玉米品种在当地种植推广。
英文摘要：
In this study,the adaptability of corn cultivars which Shendan 16 and the introduced 10 corn cultivars,to saline alkali soil in the Yellow River irrigation area is studied.The result shows that compared with Shendan 16,the yield increase of Dunyu 2 is the most obvious,and the yield of KWS 2564 and Ganxinjixiang 1 is not obvious,and the other cultivars have different levels of yield reduction.The analysis of coefficient shows that the cultivars of high coefficient are less adaptable after salt stress.The content of ion in soil layer of Dunyu 2 is lower than that of other cultivars,and the content of ion in soil layer of KWS 2564 and Ganxinjixiang 1 is lower.Dunyu 2 both in terms of salt resistance and stable yields have advantages,can be used as a salt tolerant corn cultivars planted in the local promotion.
