| Abstract: | A mathematic model,Y=37.620 86-2.099 78X21-2.030 13X22-2.677 67X23,for the application of nitrogen(X1),phosphorus(X2),planting density(X3)and the yield(Y) of 'Longshu No.8' potato had been built by the quadratic general rotational combination design.The results showed that the influencing order of three factors on the yield was planting density>nitrogen> phosphorus.The yield reached the maximum 37.62 t/hm2 when three factors were all at 0 level,that meant the application of pure N was 150 kg/hm2,P2O5 was 13... |
