Increases in N,P，K,Fe,Zn,B and Mn ferhiizer application resulifd in a remarkable change in the wheat population, tilling increases of 1.71 ?2.45 millions/hm²，yield increases of 751.5 kg/hm², and earnings increases of 840 Yuan/hm² (the average earning of effective normal fertiiizer is 3.10 Yuan/kg). Furthering this fertilizer investment, the yield increases by 1147.5 kg /hm² and earnings increase by 1347 Yuan/hm² by doubling trace elements Fe, Zn, B and Mn; trace fertilizer profit in this case is 30.71 Yuan/kg. Yield increases by 1117.5 kg/hm² and earnings increase by 1716 Yuan/hm² by doubling the trace elements and P fertilizer (the average earning of effective P fertilizer is 7.53 Yuan/kg). Yield increases by 405 kg/hm² and earnings decrease by doubling potash fertilizer. Yield increases by 945 kg/hm² and earnings increase by 1314 Yuan/hm² by increased fertilizer content of P,K,Fe,Zn，B and Mn (except N). In this fertilizer investment type, the profit increased 3932 Yuan/hm² and the earning is 17.54 Yuan/kg by doubling phosphate fertilizer. Tht experiments show that phosphate fertilizer arul irace fertilizer are a key factor in improvement of wheat production capacity and profitability of high fertilizer levels.
