摘要
通过对58个燕麦品种的基本苗、株高、鲜草产量的比较分析,筛选出最适宜在拉萨地区复种的燕麦品种。结果表明,总体表现均较好的是定燕2号基本苗40.12万株/667 m^(2),株高93.67 cm,鲜草产量5976.61 kg/667 m^(2);远杂2号基本苗24.54万株/667 m^(2),株高100.78 cm,鲜草产量5493.28 kg/667 m^(2);青引2号基本苗28.49万株/667 m^(2),株高103.67 cm,鲜草产量4522.62 kg/667 m^(2)。综合试验结果得出,定燕2号、远杂2号、青引2号更适合在拉萨进行复种。
In order to screen the most suitable oat variety for replanting in Lhasa,the basic seedling,plant height and fresh grass yield of 58 oat varieties were comparative analysis.The results showed that the basic seedling of Dingyan 2 was 401200 plants/667 m^(2),the plant height was 93.67 cm,and the fresh grass yield was 5976.61 kg/667 m^(2).Yuanza 2 basic Seedling 245400 plants/667 m^(2),plant height 100.78 cm,fresh grass yield 5493.28 kg/667 m^(2).The basic seedling of Qingyin 2 is 284900 plants/667 m^(2),the plant height is 103.67 cm,and the fresh grass yield is 4522.62 kg/667 m^(2).Based on the above test results,Dingyan 2,Yuanza 2 and Qingyin 2 are more suitable for Replanting of grain and grass in Lhasa.
