| Abstract: | The effects of N,K and planting density on the yield of maize variety Dong No.315 were studied with the application of ternary quadratic orthogonal regression rotary combination design.The mathematical model between the main cultivation factors and the output index was established.By computer simulating and optimizing,the optimal combinational scheme and high-yield cultivation model for yield above 639.1 kg/667 m2 of Dong No.315 were proposed.The result indicated that in the present agricultural production ... |
