| 摘 要： | 探讨了3种植物生长调节剂烯效唑、缩节胺和防落素对黑麦草生长特性的影响。结果表明:单独喷施烯效唑(50mg/L)和缩节胺(300mg/L)均能显著延缓黑麦草生长,矮化其株高,增加根冠比,提高叶绿素含量,其中50mg/L烯效唑的处理效果比较显著;烯效唑、缩节胺和不同浓度的防落素(50mg/L和100mg/L)混合喷施,只有烯效唑的复合使用能显著提高叶绿素含量,对改善黑麦草坪用性状的作用较好。

| Abstract: | The effects of 3 types of plant growth regulators--uniconazole （S-3307）, mepiquat ehloride（Pix） and P-chlorophenoxyacetic aeid （PCPA） on the growth of perennial ryegrass were studied by spraying on leaf surtaces. The results showed thal S-3307 （50 mg/L） and Pix （300 mg/L） not only had inhibitory effects on plant height, regenerative power and leaf length, hut also had promotive effects on the root-shoot ratio and chlorophyll content, and the effect of S-3307 （50 mg/L） was much better than that of Pix （300 mg/L）. The results also indicated that S-3307（50 mg/L） applied with PCPA had higher chlorophyll content than S-3307（50 mg/L） applied solely did. |
