| Abstract: | Through research in the intercropping system of wheat and sunflowers based on 3414 test in Hetao irrigation district of inner Mongolia,and it is established respectively one element quadratic model,two element quadratic model,three element quadratic model,linear plus platform,analyzing different models to determine the best amount of the crop local fertilizer.The results showed that the planting area ratio of the wheat and the sunflowers is 1.5∶1,the best amount of the wheat fertilizer:N 69.43 kg/hm2,P 38.89 kg/hm2,K 32.17 kg/hm2;the best amount of the sunflowers fertilizer:N 78.77 kg/hm2,P 42.54 kg/hm2,K 34.05 kg/hm2.the best amount of the crop fertilizer compared with the amount of the local customary fertilizer,the amount of N fertilize whittle down 26.62% and the amount of P fertilize whittle down 31.03% of per hectare platform. |
