施肥对野牛草生长及叶片叶绿素含量的影响

Effect of fertilization on the growth and chlorophyll content of Buffalograss

采用盆栽试验设计研究了不同氮、磷用量对野牛草生长和叶片叶绿素含量的影响,结果表明:氮的施用可明显改善野牛草的生长,表现为显著增加草屑积累量,提高生长速率和叶片叶绿素含量,但磷的效果不显著。

A pot experiment was conducted to study the influence of N and P fertilizre application on growth and chlorophyli content of buffalograss [Buchloe dactyloides （ Nutt, ） Engelm]. The results indicated that Nitrogen improved the growth of buffalograss （ Buchloe dactyloides （Nutt.） Engelm. ）. The clipping yield, the growth rate, and the chlorophyll content of buffalograss ascended significantly when nitrogen rate increased. However, phosphorus had no effects on these traits mentioned above.
