摘　　要：通过盆栽试验,研究了不同浓度的4种生长调节剂对多年生黑麦草(Lolium perenne)株高、叶长、叶宽、分蘖数及地上部植株鲜、干质量的影响。结果表明,多效唑和矮必施对多年生黑麦草株高、叶长及地上部植株鲜、干质量的抑制作用显著,但浓度过高会对草坪造成较大损伤。因此,建议选用浓度为200mg.L-1的多效唑和375mg.L-1的矮必施作为多年生黑麦草的化学修剪药剂。Abstract： A pot experiment was conducted to determine the effects of different concentrations of four kinds of growth regulators on plant height, length and width of leaf, tillers, dry weight and fresh weight of perennial ryegrass （Lolium perenne）. The results showed that the different concentration of four plant growth regulators were significantly inhibited the growth of plants. 200 mg·L^-1 Of Paclobutrazol and 375 mg·L^-1 of Aibis treatments were suggested for chemical pruning of perennial ryegrass.
