| Abstract: | A field experiment of quadratic orthogonal regressive rotation design of three factors was conducted. The mathematical models of planting density, application rate of nitrogen and phosphorus for high-yielding and other economic characters were established and the scheme of cultural practices for yielding above 2.25t/hm 2 was computed from the model as fellows: transplanting at the densities of 15.5—16.5 plants/m 2 , applying the fertilizers N 100—150 kg/hm 2 and P 2 O 5 45—75kg/hm 2 . |
