| Abstract: | Objective: To study the effect of N, P, K and sowing norm on yield of Pinellia ternate. Method: The effects of N, P, K and sowing norm were studied by means of 4 factors and 3 levels orthogonal design experiments. Result and Conclusion: The effects of the 4 factors decreased in following orders is sowing norm, N, K and P. Rational amounts of fertilizer and sowing norm are 48.0-96.0 kg·hm-2 N, 90.0 kg·hm-2P, 90.0 kg·hm-2K, 3000.0-3750.0 kg·hm-2. |
