武威南部祁连山区9个一年生牧草品比试验

Comparative Experiment of Nine Annual Forage Varieties in Qilian Mountain Area,Southern Wuwei

为了筛选适宜武威南部祁连山区种植的优良牧草品种,选择甘引1号黑麦、陇燕1号、陇燕2号、陇燕3号、定燕2号、定引1号、魁北克、白燕7号、白燕麦等9个一年生禾本科牧草品种,对其物候期、表型性状及产草量进行比较分析。结果表明,两茬累计鲜草产量陇燕3号最高,为6.42 kg/m^(2),显著高于除定燕2号、陇燕2号外的其他6个品种(P<0.05)。刈割一次的情况下,鲜草产量陇燕3号最高,为4.73 kg/m^(2),显著高于除陇燕2号外的其他7个品种(P<0.05)。经综合评价,陇燕3号、定燕2号、陇燕2号可作为武威南部祁连山区适宜种植的牧草品种。

In order to select excellent forage varieties suitable for planting in the Qilian mountain area in the southern of Wuwei,9 annual gramineae forage varieties were selected,including Ganyin 1 rye,Longyan 1,Longyan 2,Longyan 3,Dingyan 2,Dingyin 1,Quebec,Baiyan 7,and White oat.Their phenological period,phenotypic traits and yield were compared and analyzed.The results showed that Longyan 3 had the highest cumulative fresh grass yield of 6.42 kg/m^(2) in the case of second cutting,and was significantly higher than the other six varieties except Dingyan 2 and Longyan 2.Under the condition of cutting once,the fresh grass yield of Longyan 3 was the highest,at 4.73 kg/m^(2),which was significantly higher than the other 7 varieties except for Longyan 2.After comprehensive evaluation,Longyan 3,Dingyan 2,and Longyan 2 can be promoted and planted as suitable forage varieties in the Qilian mountain area of southern Wuwei.
