河西干旱灌区春小麦垄作沟灌栽培下适宜品种筛选研究

Study on Screen Suitable Varieties of Spring Wheat under Ridge Cultivation in Arid Hexi Irrigation Area

［目的］筛选出适合河西干旱灌区垄作节水栽培的高产、优质春小麦品种。［方法］于2005年进行了8个春小麦品种（系）的品比试验,调查比较它们的生育期、农艺性状、经济性状和产量。［结果］春小麦垄作适宜品种筛选结果表明，96123产量表现最好，折合产量7 257.00 kg/hm2，分别比其他品种高805.50-1 906.50 kg/hm2，其次为陇辐2号，折合产量6 451.50 kg/hm2，其余品种产量在5 341.50-6 135.00 kg/hm2，其中西旱1号产量表现最差，折合产量只有5 341.50 kg/hm2，暂不宜垄作栽培。［结论］96123可作为垄作栽培的适宜品种推广应用，陇辐2号和宁鉴210可作搭配品种。

[ Objective] The study was to screen some varieties with high-yield, good-quality characters for ridge of water-saving cultivation in Hexi irrigated areas. [ Method] The variety comparative test on 8 spring wheat varieties（lines） was conducted in 2005 to investigate and compare their growth periods, agronomic characters, economic characters, yields. [ Result ] The results showed that 96-123 had the highest yield, was 7 257.00 kg/hm2 ,805.50 - 1 906.50 kg/hm2 higher than other varieties, followed by was longfu 2nd, 6 451.50 kg/hm2. The conversion yield of the other varieties（lines） were 5 341.50 - 6 135.00 kg/hm2, Xihan 1 nd yields was lowest, 5 341.50 kg/hm2, was unfit for ridge cultivation. [ Conclusion] The 96-123 can be used as suitable varieties for ridge cultivation to extended application, the longfu 2nd and Ning jian-210 can be used with a collocation variety.
