【摘要】 论述了用不同浓度的多效唑处理阿米哥、早熟禾,草坪的高度、地下及地上生物量、色泽和一系列的 生理生化指标均有不同程度的变化。研究结果表明:300到400μg.g-1的多效唑对植株起矮化作用,有效提高阿 米哥的草坪质量和植物根系活力、硝酸还原酶活力、叶绿素含量、可溶性糖含量和脯氨酸含量;而100~200 μg.g-1的多数唑则对早熟禾有很好的作用效果。更多还原

【Abstract】 Effect of the different concentration of PP333 to the Amigo and the Annual bluegrass on the turf colour and turf quanlity, heights, biomass undergroung and biomass of overground and a seriers of physiological and biochemical were studied. The resuilts showed that the aplication of PP333 of the concentration of 300 to 400μg.g-1 improved the turf colour and enhanced the furf quanlity, raised the activity of the NR and the activity of roots system, the contents of soluble sugar, proline, and chloropyll when lowering the heights of the Amigo, so the consentration is appropriate to Amigo while the heights of the Amigo, so the consentration is appropriate to Amigo while the concentration of 100 to 200μg.g-1 is appropriate to Annual bluegrass.更多还原
