摘　　要：采用不同浓度的多效唑喷施高羊茅,对其生理指标及草坪质量进行测定与分析。结果表明:施用多效唑能增加叶片的叶绿素相对含量,丙二醛含量、过氧化氢酶活性,游离脯氨酸含量也随多效唑浓度的增加而增加;强劲的抗逆性好于红象,是聊城市适宜的草坪草;草坪质量综合得分以施多效唑浓度600 mg/m2时为最高,此时草坪草外观质量最好,为最佳施用量,2种草坪质量没有明显差异,这为多效唑在草坪养护管理上的合理应用提供了指导。Through determination and analysis of the physiological characteristic and quality characteristic, the method of spraying PP333 of different concentrations to deal with Festuca arundinacea was used in the experiment. The results showed that the usage of PP333 could improve the SPAD of leaves. Catalase （CAT） activity, the free praline （PRO） content and malondialdehyde （MDA） content increased with the increasing of concentration; ‘Qiangjin’ was the suitable lawn grass of the Liaocheng city because its’resistance was good than‘Hongxiang’ ; Lawn quality score was the highest when the concentration was 600 mg/m^2. Lawn quality was the best when the concentration was between 600 mg/m^2 , that was the best application rate. Lawn quality was not significantly difference between ‘Qiangjin’ and ‘Hongxiang’. Theoretic guide was provided for the management of lawn.
