摘要
应用植物抑制剂ＰＰ_(３３３)不同浓度和喷施不同次数对秋菊矮化的试验，结果表明有明显的矮化效果，其最佳浓度为０．０３６％，一般喷施１—２次，可降低秋菊的高度，叶片叶绿素含量增加，叶片变原，花径增大，花期延长，全面提高秋菊的观赏价值。
An experiment of plant inhibitor PP_(333) is spurted under different density and times onautumn chrysanthemum. The results show that it has been shorterned obviously, the bestdensity is 0. 036%. It is spurted for one to two times, the autumn chrysanthemum's height canbe lowered, chlorophll content and leaf thickness, dium and period of flower are increased.
