摘　　要：[目的]研究生长调节剂Primo MAXX对狗牙根草坪草生长的影响,为华南地区Primo MAXX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Primo MAXX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Primo MAXX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Primo MAXX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Primo MAXX较为适宜。[Objective] The aim was to investigate effects of primo MAXX growth regulator on growth of Bermuda grass,to provide basis for the application of Primo MAXX in Bermuda meadow.[Method] The height,leaf color 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 thickened.[Conclusion] The application of 150-300 g/hm2 effective dose of Primo MAXX to Bermuda grass in southern China is more appropriate.
