摘　　要：利用土培盆栽试验对多年生黑麦草接种菌根菌后坪草的生长、色泽以及养分吸收状况进行了探讨。结果表明 :接种菌根真菌可使多年生黑麦草根系受到侵染 ,并可明显增加多年生黑麦草叶片中叶绿素含量。 VA菌根可促进黑麦草对 P、Fe、Cu、Mg、K、B、Si、S和 N等矿质养分的吸收 ,但却使黑麦草组织中 Mn的浓度降低。The effects of Versicular-arbuscular mycorrhiza fungi on the growth, leaf color and mineral elements concentration of the perennial ryegrass were studied. The results showed that when the VAM fungi were inoculated, the roots of perennial ryegrass could be infected and the content of chlorophyll in the turfgrass leaves was increased. The VA mycorrhiza could improve the absorption of mineral elements such as P,Fe, cu, Mg, K, B, Si, S and N, but concentration of Mn was reduced.
