摘要
通过对4种画眉草的种植以及调查研究,对它们的种子形状特征与发芽率、牧草生长情况、种子产量构成要素、叶片特征、产草量及营养器官物质分配以及营养成分进行了测定并比较分析。结果表明,4种画眉草均能在嵩明地区较好的生长,引进品种弯叶画眉草Eragrostis curvula和野生种嵩明画眉草E.song-mingensis各方面性状较优,能够在该地区进一步推广应用。
Four Eragrostis varieties were studied in terms of their seed characteristics, germination rate, growth status, seed yield, leaf characteristics, biomass, nutritive composition and nutrient allocation. Results showed that 4 Eragrostis varieties gave good performance in Songming area of Yunnan province, but E. curvula and E. songrningensis were better and can be extended in the area.
