Effect of Fertilizer Application on Yield and Population of Strong Gluten Wheat Xinong 979

The effects of fertilizer application on yield and population of strong gluten wheat of Xinong 979 were studied by using different combinations of N,P,K fertilizers.The results showed that application of different N,P,K fertilizers could significantly improve wheat population at different stage,the treatment of high P had the most significant effect on population of wheat and the P fertilizer was the best.The effect on the biological yield of wheat was different at different stage by different fertilizer application and there was closely related to biological yield of wheat between winter stage and mature stage.The highest yield was obtained in the treatment of high N fertilizer,with the 33.1% yield increase than CK0.There was more significantly effect on yield of wheat by increase N and K fertilizer.The yield was increased 5.8% than farmer fertilizer level by increase K fertilizer.The yield was increased 11.8% under some N and P fertilizer level by increase K fertilizer and there was not significantly effects on yield by high K fertilizer application.The yield was increased 12.6% under some P and K fertilizer by increasing suite N fertilizer and the yield reduced 3.9% by high N fertilizer.There was not increase on yield under some N and K fertilizer level by increase P fertilizer.
