Abstract: 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.
