摘　　要：针对引黄灌区种植子粒和青贮玉米兼用品种较多的情况,研究了不同品种玉米的生物鲜重和子粒产量,并结合粗蛋白含量指标进行评价,筛选了适宜做青贮和子粒的玉米品种。研究结果表明:生物鲜产量最高的品种为张玉1355,其次为先玉1225,是较适宜的青贮玉米品种;先玉1225虽然子粒产量最高,但穗位高、易倒伏。天赐19和科河969子粒产量在供试玉米品种中并列第二,为较为适宜的子粒玉米品种;天赐19百粒重和粗蛋白含量最高,分别为36.8 g和7.3%,科河969穗位低,具有高产的潜势。Aiming at the problem that there are many varieties of seed and silage corn planted in the Yellow River irrigation area,the biological fresh weight and grain yield of different varieties of corn were studied,combined with the evaluation of crude protein content indicators,and corn varieties suitable for silage and seed were selected.The research results show that the variety Zhangyu 1355 and Xianyu 1225 with the higher biological fresh yield are more suitable silage corn variety.Although Xianyu 1225 had the highest grain yield,its ear position was as high as easy lodging and its production was low.The grain yield of both Tianci 19 and Kehe 969 rank second among all corn varieties.It is a more suitable corn variety.The grain weight and crude protein content of Tianci 19 are 36.8 g and 7.3%.The low ear position of Kehe 969 has high yield potential.
