| 摘 要： | 以多年生黑麦草为试材,研究了7种基质配比、3种施肥量下对黑麦草的叶绿素含量、根系生长情况的影响。结果表明：不同基质对多年生黑麦草叶绿素含量影响显著;随着施肥量的增加黑麦草叶绿素含量呈先增加后减少的趋势,施肥水平对黑麦草叶片叶绿素含量的影响不大,不同基质对多年生黑麦草的根长发育影响显著,不同施肥水平对黑麦草的根长影响不大,不同基质对黑麦草根系活力影响显著,不同施肥水平对黑麦草根系活力没有显著影响,在A3施肥水平时,Ⅴ号、Ⅵ号和Ⅶ号基质黑麦草根系活力远远高于其他基质的处理。Ⅶ号基质结合A3施肥水平下,黑麦草生长最好,为黑麦草的首选基质和施肥水平组合。

| Abstract: | The effects of seven types of substrates,three fertilizer level on ryegrass chlorophyll content and root growth situation with the Lolium perenne to find its suitable substrates and fertilizer levels were examined.The results showed that:impact of substrates on the chlorophyll content of ryegrass was significant;with the increase of fertilizer,chlorophyll content of ryegrass increased firstly and then decreased,impact of fertilization on chlorophyll content of ryegrass was not significant;impact of substrat... |
