To study the growth and quality under Phe,Lyr,Zn²⁺ and Cu²⁺ with different concentrations,which were controlled by foliage spray,we selected 2-year-old Lonicera japonica as the material.The results showed that:(1)Spraying the Phe,Lyr,Zn²⁺ and Cu²⁺ with different concentrations has no appreciable effect on leaf area.When increasing spraying time,the content of chlorophyll under different treatments appeared some decline in resistance.The proper concentration is helpful for the synthesis of chlorophyll.Spraying the Phe,Lyr,Zn²⁺and Cu²⁺ with certain concentration can increase the weight of flower.For example,the flowers,fresh and dry weight increased 20.1% and 51.4% than control after 1 000 mg/g Phe treatment.(2)By spraying the Phe,Lyr with different concentrations can affect the C-metabolism remarkable,but made opposite effection on N-metabolism.Zn²⁺and Cu²⁺ can exert obvious influence on carbon and nitrogen metabolism.For example,CuSO₄ and ZnSO₄ with 10 mg/L can raise the content of starch and soluble carbohydrate.(3)There was no significant difference between the content of flavonoids in flower than control except Zn²⁺.All of the content of total flavonoids was lower than that of control,but the chlorogenic acid was opposite.(4)The spraying time or concentration have more influence on the ion content of leaf.The Zn²⁺,Cu²⁺,Fe²⁺ content of flower was significantly lower than that of control except 30 mg/L CuSO₄ treatment.It can be inferred that spraying the Phe,Lyr(For 1 000 mg/g Phe,2 000 mg/g Lyr),Zn and Cu(For 50 mg/L ZnSO₄,10 mg/L CuSO₄) with proper concentration can improve the growth of L.japonica,and increase the quality and yield on the branch initial stage of the first florescence of L.japonica.
