摘要： 采用田间小区试验方法，研究了氮、磷、钾肥对金银花产量及药用成分绿原酸、木犀草苷含量的影响。结果表明，在基施生物发酵鸡粪(N-P₂O₅-K₂O=1.58-3.08-1.72)4.5 t/hm²基础上，施化肥氮(N)为0～450 kg/hm²的范围内，金银花产量随着施肥量的增加呈增加趋势，其中施氮(N)450 kg/hm²处理单株产量最高，而绿原酸含量随施氮量的增加呈先增加后降低的趋势，当施氮量超过240 kg/hm²时，随着施氮量的增加而下降，但各处理间差异未达到显著水平；磷肥能有效地提高金银花的产量，施磷(P₂O₅)为360 kg/hm²时单株产量最高，施P₂O₅量在0～180 kg/hm²的范围内，绿原酸随着施磷量增加而增加，超过180 kg/hm²时，绿原酸含量随施磷量的增加而显著下降；在施K₂O量在0～300 kg/hm²的范围内，金银花产量随着施钾量的增加而增加，而绿原酸含量以施钾量为225 kg/hm²时最高。其中当N、P₂O₅、K₂O施用量分别在240～360，180～360，150～225 kg/hm²范围内，四茬金银花药用成分木犀草苷平均含量达到《中国药典》标准的0.05%，处理间差异不显著，但超过此施肥量范围木犀草苷含量则下降。

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% ．
