摘　　要：采用盆栽试验,研究叶面喷施不同浓度烯效唑对丹参植株生长的影响。在丹参整个生长期内,动态观测植株株高、株幅及地径的变化,并对收获期丹参叶、茎、花果、根的生物量及其所占生物量比进行测定。结果表明,叶面喷施烯效唑后,丹参植株形态发生明显变化,主要表现为株高降低、株幅减小、高径比减小等。同时,丹参各器官的生物量分配情况也发生了较大变化,茎、叶所占生物量比显著减少,而根所占生物量比显著增加。因此,在丹参生长期叶面喷施一定浓度烯效唑具有明显的矮化植株、修整株型、增强抗倒伏能力的作用,在丹参规范化生产中对其合理密植,提高产量具有一定的实际意义。In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass al- location of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.
