| Abstract: | The devices of 3 factors and 2 powers saturation D were adopted in this test. Using urea, calcium superphosphate and potassium chloyide, we had quantitative studies on the issues of the optimum applying fertilizer-N, P, K and set up reaction model of fertilizer for tomato yields in the middle sheds. The optimum feritilizer dose, reaction law for output to every kind of fertilizers and interaction law were probed into respectively according to regression model. |
