Abstract:: Taking Peristrophe japonica (Thunb.) Bremek.as the research object，by using level of the orthogonal experiment design L9(33)，to explore the influence of the fertilizing treatment on its vegetative growth and flowering.The results showed that the treatments，compared with the control，were more effective for vegetative growth and normal flower induction of Peristrophe japonica (Thunb.) Bremek.(P<0.05).Among the treatments，N1P2K2 was the optimal condition to speed up the growth of the plants and it was also the most effective for flowering，about one week advanced to the emergence.The effect of fertilization was in the order of N>K>P in the growth period.K was the key factor to affect the absorption of mineral elements in the plant.The total level of N，P，K，Mg was positive correlated with it.P was the secondary factor and the contents of P and K increased with the increasing of its dosage.
