摘　　要：通过沙培混入不同重量保水剂(0g/盆、1.0g/盆、3.0g/盆、5.0g/盆),盆栽匍匐翦股颖,研究保水剂对匍匐翦股颖生长及保水效应。结果表明,高用量保水剂抑制株高和根长,叶片短,枯叶多,叶片叶绿素含量低。保水剂提高了基质持水量,断水7天后基质仍维持较高含水量。The effects of super absorbent polymer （SAP） （0 ～ 5g/pet） on water lose rate in soil and growth of Agrostis stolonifera under drought stress to 7 day through pot cultivation were studied. The results showed that SAP increased soil water content, and high content of SAP maintained higher relative water content after 7 days drought. High content of SAP in medium inhibited the growth of leaf, shoot and mot, increased withered leaf rate and decreased chloropyll content in leaves.
