| 摘 要： | 分别采用不同浓度的PP333(多效唑)、CCC(矮壮素)对黑麦草进行叶面喷施处理。结果表明,这两种药剂均减缓了黑麦草地上部分的生长,抑制叶片增长,减少草坪修剪频率,促进分蘖形成,并使叶片增厚加宽,叶绿素含量提高,因此降低了生产管理成本,提高了草坪的观赏效果。其中,以300mg/kg的多效唑的处理效果最好,且药效可以持续50～60d左右。

| Abstract: | Lolium perenne was treated with plant growth regulator- PP333 and CCC at different concentration levels. The results showed that both PP333 and CCC could slow down the growth of the leaves and other organs aboveground, reduce the frequency of lawn pruning and accelerate the tillering. After PP333 and CCC treatment, the leaves became thicker and wider, the content of the chlorophyll was increased. Therefore, the cost of production was reduced and the visual effect of lawn was improved. When Lolium perenne was treated with 300mg/kg PP333, the effect was the best and could last 50 to 60 days. |
