摘要: 以地毯草为研究对象,通过随机区组试验,初步研究不同去叶周期对地毯草克隆生长的影响。结果表明,不同的去叶周期之间存在显著或极显著性差异,中等强度去叶(D20)最适宜地毯草的生长。而过度去叶(D10)或长时间未去叶(D60)都抑制了地毯草的正常生长,从而导致地毯草草坪使用价值下降。因此,中度去叶有利于地毯草的克隆生长,提高成坪速率及其观赏价值。

Abstract: The clonal growth of carpet grass (Axonopus compressus) under periodic defoliations was studied in this randomized block experiment. There were significant, or very significant, differences between periodic defoliations and the optimum growth of carpet grass when the leaves were moderately pruned. Too high or low frequently of leaf cutting (D10 or D60) inhibited the normal growth of carpet grass and led to lower quality turf. However, moderate defoliation could contribute to clonal growth of carpet grasses and improve their ornamental value.
