| 摘 要： | 为了筛选出在渝西地区生态适应性强的鸭茅(Dactylis glomerata)品种(系),本试验从物候期、生长状况、鲜草产量、干草产量、茎叶比、农艺性状和营养成分等方面连续两年对01472、79-9、02-116、01-103、金牛、阿索斯、宝兴、安巴8个品种(系)的鸭茅进行了综合评价。结果表明,所有材料均能适应渝西地区的自然环境条件;02-116生长速度最快,连续两年干草产量最高,分别可达15 914和17 031kg·hm~(-2),金牛茎叶比(干)最低,两年分别为0.26和0.24,营养价值最高。根据干草产量和营养价值综合评价得出,02-116和金牛表现出优于其它鸭茅品种(系)的潜力,适合在渝西地区推广种植。

| Abstract: | In order to select ecologically adaptable orchardgrass cultivars (lines)in western Chongqing,the phe-nophase,growth rate,yield,stem/leaf ratio,agronomic characters,and nutrient components of eight or-chardgrass cultivars/lines were tested for two years.The results showed that all orchardgrass cultivars/lines were able to adapt to the natural environment in western Chongqing.02-116 showed the fastest growth and the highest hay yield.Aldebaran had the lowest stem/leaf ratio and the highest nutrition value.The comprehensive evaluation showed that 02-116 and Aldebaran were better cultivar/lines compared to others,suitable for plant-ing in western Chongqing. |
