| 摘 要： | 为筛选出适宜晋北农牧交错区栽培的燕麦品种,对13个燕麦品种的物候期、株高、产草量、叶茎比、营养成分干物质(DM)、粗蛋白质(CP)、粗脂肪(EE)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)和粗灰分(Ash)]以及饲用价值等进行品比试验。结果表明,不同燕麦品种株高、鲜草产量、干草产量、茎叶比及其营养成分含量之间差异显著,其中太阳神的株高最高,为133.61 cm,而梦龙的株高最低,仅92.02 cm,差异极显著(P<0.01)。牧王的干草产量最高,为10511.98 kg/hm2,与牧乐思、太阳神及科纳无显著差异(P>0.05),但显著高于其他品种(P<0.05)。牧王和牧乐思的叶茎比较高于其他品种,分别为0.31和0.28。各个燕麦品种的DM、CP、EE、NDF、ADF和Ash含量的变化范围分别为93.37%~95.29%、11.03%~12.81%、2.78%~4.45%、55.51%~65.20%、26.14%~34.39%和5.70%~7.13%。美达及贝勒的饲料相对值(RFV)显著高于其他品种(P<0.05)。综合分析结果表明,牧王、牧乐思及太阳神较其他品种更适宜在该地区推广种植。

| Abstract: | In order to screen suitable forage germplasm for the agro-pasture ecotone of northern Shanxi, phonological development, height, fresh and dry (hay) yields, stem to leaf ratio, nutrient dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fibre (NDF), acid detergent fibre (ADF), Ash] content and feeding value of 13 oat varieties were assessed. The height, fresh and hay yields, stem to leaf ratio and nutrient content of different oat varieties were significant different; Titan was the tallest variety (133.61 cm) while Magnum was the lowest (92.02 cm) (P<0.01). The hay yield of Haymaker was the higher than all varieties (P<0.05) apart from Molasses, Titan and Kona. The leaf to stem ratios of Haymaker and Molasses were higher than those of the other varieties. The ranges of DM, CP, EE, NDF, ADF and Ash contents of different varieties were 93.37%-95.29%, 11.03%-12.81%, 2.78%-4.45%, 55.51%-65.20%, 26.14%-34.39% and 5.70%-7.13%, respectively. The relative feeding value of Monida and Baler were significantly (P<0.05) higher than those of other varieties. It was concluded that Haymaker, Molasses and Titan were the most suitable varieties for extensive utilization in northern Shanxi. |
