In this paper，the effects of humic acid enhanced effect compound fertilizer on wheat yield and nitrogen utilization rate were studied in soil with different salinization degrees.Four treatments were set up:no fertilizer control(CK)，only phosphorus and potassium fertilizer control(CK1)，conventional compound fertilizer(CF) and humic acid enhanced effect compound fertilizer(HF) treatment with equal amount of nitrogen.The field experiment was conducted in three degrees of saline soil for two consecutive years of wheat to explore the effect of humic acid enhanced effect compound fertilizer on wheat yield，nitrogen uptake and dynamic change of soil ammonium nitrogen and nitrate in the whole stages of wheat.The results showed that compared with conventional compound fertilizer，1)Humic acid enhanced effect compound fertilizer treatment increased wheat yield effectively，with an average increase of 25.26%(2018)and 19.17%(2019)，and the number of ears，grains per ear and 1000-grain weight of wheat increased at different salinization degrees；2)Humic acid enhanced effect compound fertilizer promoted the uptake of nitrogen by wheat，the total accumulation of nitrogen increased by 11.40～36.75 kg/hm²(2018)and 9.90～49.80 kg/hm²(2019).In light，moderate and heavy saline soils，the yield increases of humic acid enhanced effect compound fertilizer were 31.68%，20.53%，23.56%(2018)and 33.28%，18.86%，5.36%(2019)，respectively.3)Humic acid enhanced effect compound fertilizer increased the utilization rate of N fertilizer by 6.29～16.73 percentage points (2018)and 5.47～27.69 percentage points(2019).4)Humic acid enhanced effect compound fertilizer significantly increased the nitrate content in 0～20 cm，while reduced the content of soil ammonium nitrogen.5)The degree of soil salinization directly affected the wheat yield and nitrogen absorption，etc.The application of humic acid enhanced compound fertilizer promoted the plant nitrogen absorption compared with conventional compound fertilizer，and the wheat yield and nitrogen utilization rate increased with the decrease of soil salinity.It is suggested to apply humic acid enhanced effect compound fertilizer on low and moderate salinized soil.
