中文摘要:

为筛选出适宜在齐齐哈尔地区推广种植的燕麦品种，用基于熵权的灰色关联方法对9个燕麦品种的农艺性状和饲草品质进行综合评价。结果发现，9个品种中，梦龙株高达到120 cm以上，与吉利和摩登差异不显著，但显著高于其他品种（P<0.05）；悍马鲜草产量最高（49 395 kg·hm^-2），龙牧12号干草产量最高（13 837 kg·hm^-2）。9个燕麦品种的可溶性碳水化合物（WSC）、粗蛋白（CP）、粗脂肪（EE）、酸性洗涤纤维（ADF）、中性洗涤纤维（NDF）、粗灰分（ASH）、木质素（ADL）含量和相对牧草质量（RFQ）分别为10.52%～12.55%、6.58%～9.88%、1.96%～2.83%、32.67%～39.52%、59.47%～68.34%、6.99%～10.40%、3.50%～4.47%、85.00～110.67。梦龙、龙牧12号和吉利的CP含量显著低于其他品种（P<0.05）；泰克的ASH含量显著高于其他品种（P<0.05）；龙牧12号的ADF和NDF含量均显著高于其他品种（P<0.05）。应用灰色关联度法对9个燕麦品种的农艺性状与饲草品质指标进行综合分析发现，作为饲草最适宜在该地区推广种植的燕麦品种为龙牧12号、悍马和优牧1号。

英文摘要:

In order to screen oat varieties suitable for planting in Qiqihar region, entropy weight based gray relational analysis was used to evaluate agronomic characteristics and forage quality of nine oat (Avena sativa L.) varieties. The results showed that the plant height of Menglong was more than 120 cm, which was not significantly different from Jili and Modeng, but significantly higher than the other varieties(P<0.05). Hanma showed the highest fresh grass yield (49 395 kg·hm^-2); Longmu 12 showed the highest hay yield (13 837 kg·hm^-2). The contents of water-soluble carbohydrates (WSC), crude protein(CP), ether extract(EE), acid detergent fiber(ADF), neutral detergent fiber(NDF), crude ash(ASH), acid detergent lignin(ADL) and relative forage quality(RFQ) of the nine oat varieties were 10.52%-12.55%, 6.58%-9.88%, 1.96%-2.83%, 32.67%-39.52%, 59.47%-68.34%, 6.99%-10.40%, 3.50%-4.47% and 85.00-110.67, respectively. Menglong, Longmu 12 and Jili had significantly lower CP than other varieties(P<0.05). Taike showed significantly higher ASH than other varieties. Longmu 12 showed significantly higher ADF and NDF than other varieties. Base on grey relational analysis of agronomic characteristics and forage quality, it was found that Longmu 12, Hanma and Youmu 1 are the most suitable varieties as forage planted in the region.
