Abstract
On the basis of N fertilization(195 kg/hm2) and P2O5 fertilization(120 kg/hm2),the effect of potassium fertilization on the yield and quality of good quality wheat was studied.The results showed that potassium fertilizer could improve the wheat yield and its component character.When the K2O fertilization was 0-120 kg/hm2,wheat yield could be improved 91.65 kg/hm2 with the K2O increase fertilization 15 kg/hm2.On the condition of soil nutrient content in Xinxiang City and normal N and P2O5 fertilization,K2O with the fertilization 120 kg/hm2 could significantly improved the wheat yield.However,the potassium fertilization had no obvious effect on the grain quality.
