RESUMEN
OBJECTIVE: To compare the effects of the different fertilizing levels on the output, the effective element, the content of heavy-metal, the grade and the ratio of wet to dry of Pinella ternate to obtain the best fertilize ratio on the planting. METHODS: The orthogonal desing method L9 (3(4)) was applied on the comparison between the different fertilization levels. The content of alkaloid was determined by UV spectrophotometer. The content of heavy-metal was determined by atom absorption. RESULTS: The factors that affected the output and the quality of Pinellia ternate were N > P > K. CONCLUSION: The best fertilizer combination is N 25 g/m2 ,P2O5 18 g/m2, K2O9 g/m2 and the application ratio is 2. 8: 2: 1 for them, in which the higher output and the content of alkaloid should be obtained.
