| 摘 要： | 为探明Trinexapac-ethyl和Prohexadione-Ca用于草坪化学控制的可行性,研究了其对高羊茅(Festuca arundinacea)生长发育的影响.结果显示:使用剂量高于0.095 kg/hm2时, Trinexapac-ethyl对高羊茅具有明显的矮化作用,在0.36 kg/hm2剂量下Prohexadione-Ca的抑制率可达95.2%;Trinexapac-ethyl和Prohexadione-Ca都能使植株新增鲜重显著降低,但对新增干重影响很小,Trinexapac-ethyl对植株新增干重无影响;在施用Trinexapac-ethyl的情况下,随着留茬高度的增加新增株高减少,合理留茬高度为4～6 cm;Trinexapac-ethyl和Prohexadione-Ca可以有效降低株高,从而减少草坪修剪次数. |

| Abstract: | A two-year study was undertaken to evaluate the feasibility of growth control of Trinexapac-ethyl and Prohexadione-Ca to turfgrass, more particularly, to the growth control of Festuca arundinacea Schreb.The result shows that Trinexapac-ethyl reduced the shoot height of Festuca arundinacea Schreb distinctly when the applying rate was above O. 095 kg/hm^2; while Prohexadione-Ca suppressed the shoot height by 95.2% at a 0. 36 kg/hm^2 rate. At the same time, both Trinexapac-ethyl and Prohexadione-Ca reduced the clipping fresh weight of grasses, but did not affect the clipping dry weight. When Trinexapac-ethyl was applied to clipped turf, the taller the stubble was left, the lower the re-growing plant would be. The equitable stubble height is 4-6 cm. Trinexapac-ethyl and Prohexadione-Ca could improve turf quality and reduce the shoot height and subsequently the frequency of clipping. |
