摘要: 为了筛选出适合在西藏河谷区种植的燕麦品种,本研究通过田间试验测定了9个燕麦品种的产量和营养品质。参试的燕麦品种为阿坝燕麦、青引1号、青引2号、青海444、青燕1号、林纳、边锋、加燕2号和青海甜燕麦,于2016年5月8日播种,小区面积为3 m×4 m,设3次重复。对9个燕麦品种抽穗期、孕穗期和成熟期的鲜重、干重、干鲜比、株高和叶茎比以及成熟期的营养品质[粗蛋白(CP)、粗脂肪(EE)、粗灰分(Ash)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、木质素(ADL)]进行测定。成熟期的地上部干重结果表明,青燕1号、林纳、边锋和加燕2号的产量均大于26000 kg·hm-2,青引1号、青引2号、青海444和青海甜燕麦产量为2200026000 kg·hm-2,阿坝燕麦产量低于22000 kg·hm-2。9个燕麦品种的CP、EE、Ash、ADF、NDF、ADL含量的变化范围分别为4.5%7.2%、21.7%57.3%、4.5%5.7%、24.9%35.4%、58.2%80.5%和30.6%42.0%,营养品质结果表明,青燕1号、青引2号和加燕2号的CP含量显著低于其他品种(P<0.05);边锋的NDF含量显著低于其他品种(P<0.05),青海甜燕麦含量最高;青海444的EE含量显著高于其他品种(P<0.05)。应用灰色关联度理论方法对9个燕麦品种的产量与营养品质指标进行综合分析得出,青海444、青燕1号和阿坝燕麦较其他燕麦品种更适宜在该地区种植推广。

Abstract: A field experiment measuring yield and nutritive value was conducted to select oat varieties suitable for cultivation in the Valley region of Tibet. Varieties tested were: Aba, Qingyin No.1, Qingyin No.2, Qinghai 444, Qingyan No.1, Linna, Bianfeng, Jiayan No.2, and Qinghai sweet oat; these were planted on 8th May 2016 in 3 m×4 m plots with 3 replicates. Yield measurements included fresh weight, dry weight (DW), dry matter%, plant height, leaf/stem, and nutritional quality of the nine varieties at heading, booting and maturity stages. Nutritive value measurements included crude protein (CP), ether extract (EE), crude ash (Ash), acid detergent fiber (ADF), neutral detergent fiber (NDF), and lignin (ADL), measured at maturity. For above-ground DW at maturity, the varieties could be divided into groups of high yield (>26 t·ha-1; Qingyan No.2, Linna, Bianfeng, and Jiayan No.2), medium yield (22-26 t·ha-1; Qingyin1 No.1, Qingyin No.2, Qinghai 444, and Qinghai sweet oat), and low yield (<22 t·ha-1; Aba). With respect to the nutritional quality results, the ranges observed for CP, EE, Ash, ADF, NDF, and ADL content were, respectively, 4.5%-7.2%, 21.7%-57.3%, 4.5%-5.7%, 24.9%-35.4%, 58.2%-80.5% and 30.6%-42.0%. Among variety differences in nutritive value observed were: CP, Qingyan No.1, Qingyin No.2 and Jiayan No.2 significantly lower than other varieties; ADF, Bianfeng lower and Qinghai sweet oat higher than others; NDF, Bianfeng higher and Linna lower than other varieties; EE, Qinghai 444 higher than other varieties. Based on grey relational analysis of yields and nutritional quality, it was concluded that Qinghai 444, Qingyan No.1 and Aba oats are the best performing varieties in this region.
