摘　　要：为了对忍冬的花期进行人为干预,确保金银花的产量和品质,通过花前叶面喷施尿素、磷酸二氢钾和硼砂溶液,研究其对忍冬花期的影响.结果表明,与对照组相比,磷酸二氢钾溶液处理的忍冬植株花期均延长,且低浓度的磷酸二氢钾溶液处理使始花期推后.就尿素溶液处理组来说,随着施用浓度的提高,花期会缩短,在花发育过程中植株C/N下降;3 ～6 mg/mL的磷酸二氢钾溶液有助于忍冬可溶性糖的积累,C/N随着花的发育而升高,花期较长;低浓度硼砂溶液（低于2 mg/mL）可将初始花期推迟至四月底,当浓度为3 mg/mL时,花期则提前,但总体花期时间延长.喷施3～6 mg/mL浓度的磷酸二氢钾溶液以及1 ～3 mg/mL的硼砂溶液有利于延长忍冬花期.We addressed the impact of different foliar spraying of carbamide, monopotassium phosphate and borax solutions before florescence of Lonicera japonica Thunb. to intervene its florescence and guarantee the yield and quality of honeysuckle. Results show that the florescence treated by monopotassium phosphate solution is lengthened and the first- flowering date is delayed after the treatment of low concentration monopotassium phosphate solution compared with control group. For the treatment of carbamide nitrogenous solution, florescence shortens and C/N declines in growth with the increase of its concentration. Monopotassium phosphate solution of 3 ～ 6 mg/mL contributes to accumulation of soluble sugar. C/N increases with the growth of flower and flowering time prolongs. Low concentrations borax solution （less than 2 mg/mL） can delay initial flowering phase to the end of April. Florescence advances and general flowering time prolongs for boron solution of 3 mg/mL. Phosphate solution of 3 ～6 mg/mL and boron solution of 1 ～3 mg/mL are benefit to the prolongation of honeysuckle florescence.
