不同矮化剂对小丽花植株矮化的影响

Effects of different dwarfing agent on plant dwarfing of Dahlia pinnata

研究了不同矮化剂不同浓度对小丽花植株矮化的影响,结果表明,小丽花矮化过程中,喷施2000～3000mg/kg的国光B9的矮化效果最佳,浓度过低矮化效果不明显,而浓度过高则影响开花率及植株长势。

We research effects of different Dwarfing Agent and concentrations on dwarfing of Dahlia pinnata.The result shows that spraying B9 （2000-3000 mg/kg）on Dahlia pinnata can obtain the best effect of dwarfing.Dwarfing effect was not obvious in Low Concentration and flowering and growth were effected in too high concentration.
