摘　　要：为了筛选适宜在高寒农区种植的春小麦新品种,2019—2020年在拉龙村引进试种了"高原437""藏春951""藏春11号"等春小麦新品种,通过田间观察鉴定其适应性和稳产性,为当地小麦生产提供理论依据。鉴定结果显示:春小麦"藏春11号"生育期适中,分蘖力强,产量稳定,在拉龙村正常成熟且产量较高,适宜进一步示范种植;"藏春951"由于生育期较长,按照当地的生产习惯不能完全成熟,籽粒产量偏低,但该品种生物产量较高,可作为半农半牧区饲料补给品种;"高原437"生育期偏长,在当地成熟度较差,如果适当调整播种期,在相邻海拔3 900~4 000 m的区域可以正常成熟,产量潜力较大。In order to screen new spring wheat varieties,which are suitable for planting in alpine agricultural areas,new spring wheat varieties such as"Gaoyao437""Cangchun 951"and"Cangchun 11"were introduced and planted in Lalong Village from 2019 to 2020. Through field observation,their adaptability and stable yield were identified,which provided theoretical basis for local wheat production. The identification results showed that spring wheat"Cangchun 11"had moderate growth period,strong tillering ability,stable yield,normal maturity and high yield in Lalong Village,which was suitable for further demonstration planting. "Cangchun 951" had a longer growth period,which can not mature completely according to the local production habits,and lower grain yield,but it had higher biological yield and can be used as feed supplement variety in semi-agricultural and semi-pastoral areas."Plateau 437"had a long growth period and poor maturity in the local area. If the sowing time is properly adjusted, "Plateau437" can mature normally in the adjacent area with an altitude of 3 900~4 000 meters,and the yield potential is large.
