摘　　要：研究结果表明：烯效唑浸种处理对高羊茅的分蘖数影响小显著，但具有降低草坪生长速度和促进叶片增宽的作用，且随着烯效唑浓度增大作用增强，同时其幼苗见绿期比对照晚7～11d；用烯效畔淋土具有降低高羊茅分蘖数和单坪生长速度、促进叶片增宽的作用，而且幼苗见绿期比对照晚9～10d；烯效唑喷叶处理后，高羊茅的生长速度显著低于对照。To resolve the problems of tall fescue growing too fast and pruning highly frequent, one new type lawn growth retardant ＂unieonazole＂ which can postpone tall rescue growth rate effectively was used. By soaking seeds, spraying on soil and leaves with uniconazole, the effects of uniconazole on tall fescue were significant. The results showed that soaking seeds with uniconazole can reduce tall fescue growth rate, widen leaves gradually along with the increase of uniconazole concentration, and postpone period of seedlings appearing green by 7-11 days, but had no remarkable effects on its tillers. However, the quantities of tillers can be indistinctively reduced by spraying on soil, which can also reduce the growth rate and widen leaves. The period of seedlings appearing green was postponed by 9- 10 days. As same as two above-mentioned methods, growth rate of tall fescue can be remarkably reduced by spraying on their leaves, too.
