菊花切花后处理菊花应在离地面约10厘米处切断,这样可避免切到不大能吸水的木质组织。切割时,剥去茎下部三分之一处的叶,并尽快将花茎放进含有生物杀灭剂的水中以预防微生物侵塞进木质部。对菊花最有效的生物杀灭剂是含硝酸银的水,有效浓度为25ppm,或者将花茎短暂泡浸在含有1000 ppm硝酸 Chrysanthemum Cut Flowers Chrysanthemum should be cut approximately 10 cm above the ground to avoid cutting to non-absorbable woody tissues. When cutting, peel the leaves at the lower third of the stem and place the stems in the biocide-containing water as soon as possible to prevent microbial invasion into the xylem. The most effective biocide for chrysanthemum is silver nitrate-containing water at an effective concentration of 25 ppm or by briefly immersing the stems in a solution containing 1000 ppm nitric acid
