| Abstract: | The theoretical optimum amount of fertilization was calculated using the quadratic regression equation on three factors. Combined with the analysis of the ‘3414＇ experiment and the production practice, the optimum amount of fertilization of Xudao No. 4 planted on the desahing soil and silt soil was suggested in Guannan, Jiangsu Province, including N 304. 5 - 348.0 kg/hm^2, P2O5 52. 5 - 64. 5 kg/hm^2 and K2O 51.0 - 70. 5 kg/hm^2. |
