摘要:本试验选用 5 个鸭茅新品系(01472,01-103,79-9,金牛和阿索斯),及对照品种
宝兴和安巴,从物候期、生长速度、产量、质量、营养成分、形态农艺指标等方面综合评定
其在雅安的适应能力。结果表明:1)01472、79-9、01-103 为早熟型,金牛、阿索斯为晚熟
型,可用于满足不同生产市场需求;2)在整个生长发育过程中,01472 生长速度增幅大,
明显高于其他材料;3)在参试材料中,金牛品质好,01472 产量高,随刈割次数增加,金
牛产量增幅明显,01472 品质逐渐提高;4)01472 具有较好的再生性及抗逆性,金牛营养价
值和适口性好;5)各参试材料的植物学形态特征差异显著,尤其在旗叶长度、株高、穗叶
距上表现为极显著。通过对试验材料适应性的研究,为鸭茅品种选育和优良饲草畜牧业供应
做下铺垫。

Abstract: In this study, the adaption of seven orchardgrass were been evaluated in Ya’an, China,
including 5 new breeding lines (01472, 01-103, 79-9, Aldebaran and Athos) and 2 cultivars
(Baoxing and Amba), which from phenophase, regrowth, yield, quality, nutrition, morphology and
agronomic traits, compared with Baoxing and Amba. Results were as follows: 1) 01472, 79-9 and
01-103 were precoucius types, but Aldebaran and Athos were late maturing types, which has
directive function for the needs of different production; 2) In the whole
