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
Different concentrations of paclobutrazol (0.8, 1.0 and 1.3 mg g) were applied to the leaves of tall fescue turf to study the effects of paclobutrazol on the growth characteristics of tall fescue. The results showed that the three kinds of different concentrations of paclobutrazol treatment showed significantly inhibited the growth of the upper part of the tall fescue turfgrass growth effect, 1.3mg g of paclobutrazol treatment so that tall fescue growth rate and pruning significantly reduced 1.0mg g Of paclobutrazol significantly increased the density of tall fescue turfgrass, significantly promoted the tillering of tall fescue, and significantly decreased the chlorophyll content of fescue
