多效唑对高羊茅草坪草生长特性的影响

采用了不同浓度的多效唑（0．8、1．0、1．3mg/g)对高羊茅草坪进行叶面喷施，以研究多效唑对高羊茅生长特性的影响。结果表明：3种不同浓度的多效唑处理均表现出显著抑制高羊茅草坪草地上部分的伸长生长的效果，1．3mg/g的多效唑处理使高羊茅生长速度和修剪量明显降低1．0mg/g的多效唑使高羊茅草坪草的密度显著增加，明显促进高羊茅的分蘖，却使高羊茅叶绿素含量明显降低。

Effect of multiple-effect-triazole on growth characters of tall fescue

In order to study the effect of multiple-effect-triazole (MET) on the growth speed of tall fescue, three different concentrations (0.8?1.0 and 1.3 mg/g) of MET were sprayed on the leaf of tall fescue lawn. The results showed that all three concentrations restrained the growth of the tall fescue above-ground. At the dosage of 1.0 mg/g, the grass density, number of tiller were increased, but chlorophyll content was decreased. However, at the dosage of 1.3 mg/g, the growth speed and cutting quantity were declined.
