The effects of row spacing,density and nitrogen rate on the yield of maize variety Jindan 65 were studied with the application of ternary quadraticor thogonal regress ionrotary combination design.The math ematical model between the main cultivation technology and the output index was established.By computer simulating and optimizing,the optimal combinational scheme and high yield cultivation model for yield above 11 777 kg/hm2 of Jindan 65 were proposed,namely the row spacing was 55 cm,the density was 47 385 the plants/hm2,the pure nitrogen rate was 415 kg/hm2 (46%of urea reduced pure nitrogen)
