摘　　要：分别对海滨雀稗品种至尊和白金建植的果岭喷施抗倒酯Trinexapac-ethyl(TE),研究在夏冬两季不同浓度TE对2种海滨雀稗果岭化学修剪的影响。结果表明,不同浓度TE对海滨雀稗果岭的修剪草屑量、草坪色泽、垂直生长速度、根冠比有很大的影响,季节的变化会明显影响TE的作用效果。在华南地区,夏季TE的化学修剪效果明显,其中,至尊果岭最适宜施用的TE浓度为5mL/100m2,而白金果岭TE使用浓度为4mL/100m2;冬季,TE在果岭的化学修剪效果不明显。Experiment was conducted to study the effect of Trinexapac-ethyl （TE）with different dosages on the chemical pruning of greens established with two cultivars of Paspalumvaginatum （Supreme and Platinum） during summer and winter in order to provide the basic information for the use of TE in south China.The re-sults indicated that different dosage of TE showed a significant impact on clipping ammount,color and lustre, vertical growth rate,and root to shoot ratio.Besides,the effectiveness of TE application in different seasons var-ied.In southern China,the effect of chemical pruning of TE is obvious,and the optimal dosage for Supreme was 5 mL/100 m2 and 4 mL/100 m2 for Platinum in summer.The effect of TE on chemical pruning is not significant in winter time.
