摘要
对4个居群白羊草(Bothriochloa ischaemum)在晋中的生长适应性性状指标,包括干草产量、干鲜比、叶茎比、株高、秆粗、节数、叶片数、粗蛋白质等,进行了灰色关联分析。结果表明,在晋中地区生产性能表现最好的是太谷居群,其次为平定和代县居群,而平鲁居群的生产性能较低。各项指标的权重大小顺序为:粗灰分>中性洗涤纤维>酸性洗涤纤维>秆粗>节间长>叶长>粗脂肪>单株干重>叶宽>株高>叶茎比>干鲜比>粗蛋白质>节数>干草产量>叶片数。
In the present study, adaptation performance characteristics including hay yield, hay fresh ratio, leaf stem ratio, plant height, stem diameter, internode number, leaf number, and crude protein of four B. ischaernum populations grown in the Jinzhong areas of Shanxi Province were measured and analyzed by the grey correlative system. The productive performance of Taigu population was best in the studied area, Pingding and Dai County populations followed, whereas the Pinglu population had relatively low adaptive productivities. The order of weight index in the grey correlation analysis was： Ash 〉 NDF〉 ADF 〉 stem diameter 〉 internode length 〉 leaf length 〉 EE 〉 biomass per plant 〉 leaf width 〉 plant height 〉 leaf stem ratio 〉 hay fresh ratio 〉 CP 〉 internode number 〉 hay yield 〉 leaf number.
