探讨了喷施不同浓度的矮壮素和一定浓度的多效唑对建植五年的高羊茅草坪质量的影响。结果表明，施用矮壮素可延缓高羊茅的生长速度，随着浓度的增加延缓作用加强，高羊茅的地下生物量及抗病性随矮壮素浓度增加而提高，低、中浓度的矮壮素改善了高羊茅的颜色、整齐度，随着浓度增加，这种作用由促进转为抑制，矮壮素以２００μｇ／ｇ 浓度为宜；施用多效唑可延缓高羊茅的生长速度，促进地下生物量积累，增强抗病性，但抑制分蘖，对颜色、整齐度有伤害作用。
The effects of spraying different concentrations of CCC and PP333 on the quality of tall fescue turfgrass grown for five years were discussed. The results showed that the application of CCC could slow the growth of tall fescue, with the increasing of the concentration, the retarding effect was strengthened. The underground biomass and disease resistance of tall fescue increased with the increase of CCC. The contents of low and medium Chlormequat improved the color and uniformity of tall fescue. With the increase of concentration, this effect was changed from inhibition to inhibition. Chlormequat at 200 μg / g was the best. Paclobutrazol could delay the growth of tall fescue, Promote the accumulation of underground biomass, enhance disease resistance, but inhibit tillering, the color, uniformity of injury.
