| 摘 要： | 目的]品种和海拔是影响燕麦草产量和品质的重要因素,高产品种可以提高干草产量20%以上,而且茎叶比也不同,产量越高,叶量越丰富,其干草产量和品质均高。所以,不断进行品种比较试验,引进新品种,对燕麦草生产的效益影响重大。方法]试验研究了不同品种的燕麦在不同海拔地区的产量及品质的差异。结果]经研究,青海444在甘南州不同海拔地区表现出良好的适应性,林纳和加燕2号在低海拔区产量较高,但在高海拔地区的产量不及本地燕麦。从茎叶比和营养物质含量分析,林纳和加燕2号的茎叶比较高,ADF和NDF的含量较低,因此,其品质好于青海444和本地燕麦。结论]综合考虑燕麦草产量与品质2个因素,在甘南州低海拔地区适合推广林纳和加燕2号,高海拔地区适合种植本地燕麦和青海444。

| Abstract: | Objective] Variety and altitude are the important factors influencing the yield and quality of oat grass.High-yield varieties can increase hay yield by more than 20%, and with higher the yield, the stem leaf ratio is more abundant. Therefore,varieties comparison experiment and the introduction of new varieties have a great influence on the benefit of tall oat grass production.Method] This experiment studied the variety of oats in the differences in yield and quality at different altitudes.Result] After research, Qinghai No.444 different altitudes in Gannan area showed good adaptability, and Linna and Jiayan No.2 locating in low altitude area showed the abundant yield, but in high altitude areas, the yield was not as good as local oats. From the stem leaf ratio and nutrient content analysis, Jiayan No.2 cauline leaf was quite high, ADF and NDF content was low. Therefore, its quality was better than Qinghai NO.444 and local oats.Conclusion] Considering two factors of yield and quality of oat grass, it is suitable to promote Linna and Jiayan No. 2 in low altitude area of Gannan area, and it is suitable for planting local oats and Qinghai No. 444 in high altitude areas. |
