【摘要】 基于熵权赋权法,运用灰色系统理论中的灰色关联度法对26个燕麦品种的生产性能进行综合评价,结果表明,生产性能综合表现较好的是初岛燕麦、青永久409、青永久709及青永久316;青永久18综合评价值最低,生产性能最差,其余品种生产性能表现一般。经逐步回归分析,发现其中的绿叶数、叶长、茎叶比、鲜干比、生长速度、叶面积指数、相对生长速率及生长天数8个指标对饲用燕麦生产性能贡献显著。更多还原

【Abstract】 The productive performance of 26 oat(Avena sativa L.) varieties was evaluated by gray systematic theory based on Entropy weight.The results showed that ChuDao,Qingyongjiu409,Qingyongjiu709 and Qingyongjiu316 performed well,Qingyongjiu18 was the poorest,and the others were kept in the middle.At the same time,through regression analysis,found that the number of green leaves,length of leaf,ratio of stem-to-leaf,ratio of fresh-to-dry,growth speed,LAI,RGR and growth days contributed greatly to the productive performance.更多还原
