摘　　要：土施保水剂(用量为0～12.5g/盆)盆栽狼尾草(Pennisetum alopecuroides(L.)Spreng.),断水10天,测定基质失水率、叶片含水量.结果说明,适量保水剂提高了基质持水量,断水10天后幼苗叶片仍维持较高的含水量和叶绿素含量.The effects of super absorbent polymer （0～12.5g/pot） on water lose rate in soil and relative water content in leaves of seedling of Pennisetum alopecuroides under drought stress to 10 day through pot cultivation were studied. The results showed that appropriate use of super absorbent polymer increased soil water content, maintained higher relative water content and chloropyll content in leaves after 10 days drought.
