Abstract
By adopting the double optimal value method, the annual optimal amount of nitrogen fertilizer and the ratio of nitrogen fertilizer distributed among crops in the system of wheat relay intercropping with corn and peanut is studied in sandy soil. The results show that the annual optimal total amount of nitrogen fertilizer applied in this system is 311.1 kg/hm2 and the suitable distributive proportion of the fertilizer is 33. 7:35. 1:31. 2 among the three crops. It indicates that the applying amounts are 104.8 kg/hm2 , 27.3kg/hm2 and 72.8kg/hm2 in natural area for wheat, corn and peanut respectively, and the annual amount fertilized is 204.9kg/hm2 per natural hectare. Though it decreases by 29.9% compared with the rate determined by conventional fertilization for each sole crop, the yields of wheat, corn and peanut and total yield gained increase by 9.3%, 3.7% , 4.8% and 6.3% respectively.
