Abstract: This research was studied the effects N， P and K fertilizer on yields， Chlorogenic acid and Luteolin ofLonicera japonica Thunb by the field plot experiment． With the basal application of biological fermentation of chicken manure ( N-P₂O₅ -K₂O = 1 ． 58-3 ． 08-1 ． 72) 4． 5 t /ha， the yields of Lonicera japonica Thunb was increasing withthe increasing of amount of fertilizer N application at the range of 0 － 450 kg /ha． When the amount N was 450 kg /ha，the yields achieved the maximum． Chlorogenic acid content decreased after the first increase with the increased amount of nitrogen． When the nitrogen application was more than 240 kg /ha， chlorogenic acid content decreased withincreasing amount of nitrogen， but there were not significant differences among the treatments． P fretilizer could effectively improve the yield， single strains yield was the highest when P2 O5 360 kg /ha． Within the range of 0 － 180kg /ha chlorogenic acid increased with increasing P₂O₅ application． Chlorogenic acid content significantly decreasedexceed 180 kg /ha． Within the range of 0 － 300 kg /ha， the yields increased with increasing of the amount of K ferlilizer． The content of chlorogenic acid achieved the maximum when the amount of K2 O ferlilizer were 225 kg /ha．When the amount N， P₂O₅ ， and K₂O were 240 － 360， 180 － 360， 150 － 225 kg /ha respectively， the Luteolin contentachieved 0． 05% ．
