摘要
[目的]满足粮农对高产、优质、广适和多抗玉米新品种的需求,使粮食持续增产.[方法] 2015年通过不同海拔地区玉米新品种田间对比试验,对玉米产量、主要经济性状、主要农艺性状、生育期和抗逆性等指标进行分析.[结果]芮单26和永瑞16可以在海拔2200 m以下地区推广种植;华兴单88可以在海拔1 750 m以下地区推广种植,其他品种需进一步试验.[结论]该研究结果可在该地区和其他类似地区推广应用,将有效促进玉米品种更新换代,提高单位面积产量.
Abstract
[Objective] The aim was to obtain maize new varieties with high yield,high quality,wide adaptability and multi resistance ability,continuously increase grain yield.[Method] Through field demonstration test of maize new varieties in different altitudes area in 2015,maize yield,main economic characters,agronomic traits,growth period and resistance were comprehensively analyzed.[Result] Ruidan 26 and Yongrui 16 could be cultivated in the area below altitude of 2 200 m;Huaxingdan 88 could be cultivated in the area below altitude of 1 750 m,other varieties should be further tested.[Conclusion] The research results can be applied in this area and other similar areas,which will effectively promote the upgrading of maize varieties and improve the yield per unit area.
