Abstract

Increases in N ,P.K,Fe,Zn,B and Mn ferhlizer application resulted in a remarkable change in the wheat population, tilling increases of 1. 71 ~ 2. 45 millions/hm2, yield increases of 754. 5 kg/hm2, and earnings increases of 840 Yuan/hm2 (the average earning of effective normal fertilizer is 3. 10 Yuan/kg). Furthering this fertilizer investment, the yield increases by 1 147. 5 kg/hm2 and earnings increase by 1 347 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 1 417. 5 kg/hm2 and earnings increase by 1 7 Hi 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 1 314 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. The experiments show that phosphate fertilizer and trace fertilizer are a key factor in improvement of wheat production capacity and profitability of high fertilizer levels.
