| Abstract: | The optimum combination program of N, P, and K in the basic fertilizer on the cold type turf was studied by using three factors saturated optimum design and gray game decision method. The result showed that the optimum combination of N, P, K mixed fertilizer in the basic fertilizer of the turf was N∶P_(2)O_(5)∶K_(2)O=(9.91∶ 7.78∶ 4.63). And the optimum amount of fertilization is 108 g /m~(2) under the environment condition of this experiment. |
