Effect on the Yield of Artemisia annul using Different Amount of Fertilizer of N,P,and P

Objective To study the effect on the yield of Artemisia annul using different amount of N,.P,K.Methods The field experiment was designed by the orthogonal experiment of four factors and three levels.Results It has no marked difference using different amount of N.P.K.Conclusion The dosage of potassium fertilizer has greater influence on the yield of leaf and bud, and the suitable quantity is 8kg/mu;the dosage of nitrogen fertilizer has greater effect on the yield of seed, and the suitable quantity is 12kg/mu.
