摘　　要：为满足西藏高海拔(半农半牧)区农牧民日常粮油所需,缓解青稞连作危害等问题,通过对混作和单作两种种植方式进行比较,得出:1)单作油菜藏油3号的农艺性状综合表现最好、产量最高,油菜籽产量为2 254.46 kg/hm^(2),综合效益最高,为14 665.14元/hm^(2);单作青稞藏青3000的农艺性状综合表现最好、产量较高,青稞产量为4 382.19 kg/hm^(2),综合效益为12 531.64元/hm^(2),排名第2;2)在青稞油菜混作中,LQH的拉孜小油菜和青稞藏青3000的农艺性状综合表现最差,而拉孜小油菜的油菜籽产量最高,为942.69 kg/hm^(2),青稞藏青3000的产量最低,为1 821.65 kg/hm^(2),综合效益最高,为9 524.47元/hm^(2)。In order to meet the daily grain and oil needs of farmers and herdsmen in Xizang's high-altitude(semi agricultural and semi pastoral)ar-eas,and alleviate the harm of highland barley continuous cultivation,this study compared the mixed cropping and monoculture planting methods,and concluded that(1)monoculture Zangyou 3 had the best comprehensive performance of agronomic traits and the highest yield.The yield of rape-seed is 2254.46 kg/hm^(2),with a comprehensive benefit of 14665.14 yuan/hm^(2).The comprehensive performance of agronomic traits and higher yield of monoculture barley Zangqing 3000 are the best.The yield of barley is 4382.19 kg/hm^(2),and the comprehensive benefit is 12531.64 yuan/hm^(2).(2)In the mixed cropping of barley and rapeseed,the agronomic traits of LQH's Lazi rapeseed and barley Zangqing 3000 were the worst;The yield of Lazi small rapeseed is the highest,942.69 kg/hm^(2),while the yield of barley Zangqing 3000 is the lowest,1821.65 kg/hm^(2).The best comprehensive ben-efit is 9524.47 yuan/hm^(2).
