摘　　要：[Objective] The aim was to investigate the effects of Primo MAXX growth regulator on growth of Bermuda grass,explore appropriate application concentration of Primo MAXX on Bermuda grass,and provide basis for the application of Primo MAXX in Bermuda meadow.[Method]The height,leaf colour and the aerial part＇s fresh weight of Bermuda grass treated with different concentrations were researched using single factor random block test.[Result]Primo MAXX application effectively reduced the height in all treatment without significant difference;appropriate application of Primo MAXX can enrich the color;and 35 days after application,Bermuda grass roots were become thicker.[Conclusion]The application of Primo MAXX with effective dose of 150-300 g/hm2 on Bermuda grass in southern China is more appropriate.[目的]研究生长调节剂PrimoMAXX对狗牙根草坪草生长的影响,为华南地区PrimoMAXX在狗牙根草坪上的应用提供依据。[方法]采用单因素随机区组试验设计,研究不同浓度的PrimoMAXX对狗牙根草坪草自然生长高度、叶色及地上部鲜重的影响。[结果]不同浓度的PrimoMAXX对狗牙根的生长高度有较好的抑制作用,且各浓度之间差异不显著;适量施用PrimoMAXX可以丰富草坪色彩;施药后35d狗牙根茎变粗。[结论]在华南地区狗牙根草坪上使用有效剂量为150～300g/hm2的PrimoMAXX较为适宜。
