采用田间小区试验方法研究了施用氮、磷、钾肥对黄芩产量、氮磷钾养分吸收及黄芩苷含量的影响。结果表明：N、P2 O5、K2 O用量分别在0～225，0～270，0～270 kg/hm2时，黄芩根产量及黄芩苷含量随着氮、磷、钾肥用量的增加而增加。其中，氮肥对黄芩产量的增加效应最大，磷、钾肥次之；施用氮肥黄芩产量提高幅度可达73．61％～105．10％。在本试验条件下，当N、P2 O5、K2 O用量分别为225，270，270 kg/hm2时，N∶P2 O5∶K2 O的比例为1∶1．2∶1．2时，黄芩根产量达到7158．00～7403．55 kg/hm2；黄芩苷为9．92％～11．24％，高于《中国药典》规定标准9．0％。

This experiment was carried out with the single factor randomized block design ,which studied the effect of N,P,K on root yield,nutrient absorption and baicalin content of Scutellaria baicalensis by field plot experi-ment.The amount of N,P2O5,K2O in 0-225,0-270,0-270 kg/ha,the root yield of Scutellaria baicalensis in-creased with increasing application amount of nitrogen ,phosphorus and potassium fertilizer .The nitrogen fertilization had the most significant effect on increasing yields of Scutellaria baicalensis,and compared with no nitrogen treat-ment,the yield of treatment with nitrogen increased 73.61%-105.10%.when the N,P2O5,K2O application were respectively 225,270,270 kg/ha,root yield of Scutellaria baicalensis were 7 158.00 -7 403.55 kg/ha,baicalin concent were 9.92%-11.24%and exceeded the regulation standards of 9.0%of Chinese pharmacopoeia .
