| 摘 要： | 在灰色系统下,对10个苜蓿品种在朝阳地区的生产性能用株高、再生速度、干草产量、分枝数、叶量等指标进行分析,建立品种评价模型,综合评价各品种的生产性能。结果表明,在朝阳地区生产性能表现较好的苜蓿品种有WL-232、CW-272、苜蓿王、阿尔冈金等,而保丰、创新、敖汉等国内品种生产性能值较低。根据各项指标的权重比较再生速度所占的权重>株高>叶量>干草产量>分枝数。

| Abstract: | The grey relevancy coefficient method has been widely used in systematic evaluation in recent years,in which the distribution of all variables is blurred and analyzed by calculating the grey relational degrees.In this study,the productivity performances in Chaoyang of 10 alfalfa cultivars were evaluated using indexes including plant height,regrowth speed,hay forage yield,branch number,and leaf yield.A comprehensive cultivar evaluation model was established.The results indicated that in the Chaoyang area,cultivars including WL-232,CW-272,Alfaking and Algonguin have relatively good productive performance,while Baofeng,Chuangxin,Aohan and other local cultivars have relatively low productivity.The order of 5 indexes in the grey relevancy analysis for weight was: regrowth speed>plant height>leaf yield>hay forage yield>branch number. |
