摘要
为筛选在鲁南地区适宜种植的饲用燕麦品种,基于主成分分析法和隶属函数法对11个燕麦品种的株高、鲜草产量、干草产量、茎叶比、粗蛋白含量、中性洗涤纤维含量和酸性洗涤纤维含量、相对饲草品质及分蘖数等方面进行综合分析。结果显示,青海444株高最高(122.3 cm),燕王株高最低(88.0 cm),但其鲜草产量最高达到66.70 t/hm^(2)。干草产量最高的是牧王16.12 t/hm^(2),林纳的鲜草产量(29.83 t/hm^(2))和干草产量(9.63 t/hm^(2))均最低。11个燕麦品种的茎叶比、中性洗涤纤维、酸性洗涤纤维、粗脂肪含量、粗蛋白、粗灰分、分蘖数及相对饲草品质含量范围分别为1.34~2.23、46.28%~63.18%、33.11%~42.63%、7.62%~12.57%、7.61%~12.33%、8.38%~11.76%、1.3~2.4、175.95~246.15。试验表明,魄力、燕王、牧王、甜燕麦、青引1号综合表现优异,可以在鲁南地区推广种植。
In order to accurately evaluate the adaptability of different forage oat varieties in south Shandong region,the plant height,fresh grass yield,hay yield,stem leaf ratio,crude protein content,neutral detergent fiber content and acid detergent fiber content,relative forage quality and fraction number of 11 oat varieties were analyzed based on principal component analysis and membership function method.The results showed that the plant height of Qinghai 444 was the highest(122.3 cm),and that of Yanwang was the lowest(88.0 cm),but its fresh grass yield was the highest(66.70 t/hm^(2)).The hay yield of Muwang was the highest(16.12 t/hm^(2)),and the fresh grass yield(29.83 t/hm^(2))and the hay yield(9.63 t/hm^(2))of Linna was the lowest.The stem leaf ratio,neutral detergent fiber,acid detergent fiber,crude fat content,crude protein,crude ash,tiller number and relative forage quality content of 11 oat varieties were 1.34~2.23,46.28%~63.18%,33.11%~42.63%,7.62%~12.57%,7.61%~12.33%,8.38%~11.76%,1.3~2.4,175.95~246.15,respectively.The experiment indicates that the comprehensive performance of Yingli,Yanwang,Muwang,Tianyanmai and Qingyin No.1 was excellent,which could be popularized in southern Shandong.
