摘要
[目的]研究多效唑(PP333)对勋章菊营养生长的影响。[方法]以3个品种勋章菊实生苗为研究对象,研究不同浓度多效唑与不同施药方法(叶喷与灌根)对不同生长时期(30、45、60 d)勋章菊营养生长的影响。[结果]叶喷40 mg/L的PP333对"白火焰"和"鸽子舞"营养指标的抑制效果最好,50 mg/L的PP333叶喷处理"黄火焰"和灌根处理"白火焰"对营养指标的抑制效果较好。[结论]该研究可为勋章菊营养生长的调控提供试验数据。
[ Objective]To study the effect of PP333 on vegetative growth of Gazania rigens. [Method]The effects of PP333 with different concentra-tions ,different application methods （foliar spray and radicular irrigation） badge in different growth periods on different species of G. rigens plant- let were investigated. [ Result] The best way of inhibiting＂ White Flame” and “Red with Ring” nutrition indicators was foliar spray with 40 mg/L of PP333 ,while“Yellow Flame” was 50 mg/L PP333 . The best concentration of radicular irrigation that inhibiting“White Flame” of nutrition indica-tors was 50 mg/L PP333 . [ Conclusion] The study provided experimental data for regulating the vegative growth of G. rigens.
