摘要
为探索不同鸭茅(Dactylis glomerata)品种(系)间的差异,2012-2014年在四川雅安进行鸭茅3个品种(系)的比较试验。结果表明,参试的鸭茅品种(系)中,‘宝兴’和‘滇北’为早熟型,而‘金牛’为晚熟型,其利用时间更长。干草产量方面,2013年‘滇北’产量最高,为11 443kg·hm^(-2);2014年‘宝兴’产量最高,为8 101kg·hm^(-2)。方差分析表明,2013年‘金牛’的产量与‘滇北’和‘宝兴’均差异显著(P<0.05),而‘滇北’与‘宝兴’差异不显著(P>0.05);2014年参试的鸭茅3个品种(系)产量间均差异不显著(P>0.05)。‘金牛’的茎叶比最低,表明其叶量丰富。从营养成分分析来看,蛋白质年平均含量从高到低依次为‘金牛’(21.63%)、‘滇北’(20.70%)和‘宝兴’(20.37%),‘金牛’的粗蛋白含量较‘滇北’和‘宝兴’分别高0.93个百分点和1.26个百分点。综合来说,‘金牛’的品质更加优异。
To explore the discrepancies among several different orchardgrass（Dactylis glomerata）cultivars（lines）,cultivars comparative tests were conducted with three orchardgrass cultivars（lines）in Ya＇an from2012 to 2014.The results showed that‘Baoxing＇and ‘Dianbei＇were early-maturing,while‘Aldebaran＇was late-maturing which can be used for longer time.‘Dianbei＇had the highest yield of 11 443kg·ha-1 in 2013,while‘Baoxing＇had the highest yield of 8 101kg·ha-1in 2014.In 2013,the yields of‘Aldebaran＇had significant difference with the yields of‘Baoxing＇and‘Dianbei＇（P〈0.05）,although the latter two had no significant difference（〉0.05）.In 2014,there was no significant difference among these three cultivars（lines）.Comparing with other two cultivars,‘Aldebaran＇had the lowest stem-leaf ratio,indicating rich leaves.The results of nutrients analysis showed that the rank of protein content from high to low was ‘Aldebaran＇（21.63%）,‘Dianbei＇（20.70%）,and‘baoxing＇（20.37%）,and the crude protein content of‘Aldebaran＇exceeded‘Dianbei＇and‘Baoxing＇by 0.93%and 1.26%,respectively.In summary,‘Aldebaran＇had better quality than‘Baoxing＇and‘Dianbei＇.
