Under field test condition，eight kinds of fertilization treatments were set up in the salineized cultivated land of the West Liaohe Plain，namely control(CK)，organic fertilizer(M)，straw return(S)，chemical fertilizer(F)，organic fertilizer+straw return(MS)，organic fertilizer+chemical fertilizer(MF)，straw return+chemical fertilizer(SF)，organic fertilizer+straw return+chemical fertilizer(MSF)，and the effects of different fertilization measures on soil salinity characteristics and maize yield in salineized cultivated land were studied.The results showed that the pH was significantly lower than that without fertilization(P<0.05)under the application of MF and MSF，and the soil pH was the lowest in MF treatment and 13.41% lower than that of CK in the 0-10 cm soil layer.The alkalinization degree was the lowest in MF treatment，which was 35.45% lower than that of CK.Compared with CK，all fertilization treatments significantly reduced the content of harmful ions Cl- and Na+，and the differences between treatments were significant.It could be seen that the addition of organic fertilizer and straw had an obvious effect on the improvement of soil physical and chemical properties.MSF treatment processed the highest yield of corn，reaching 12231 kg/hm²，with an increase of 58.87%，compared with CK.There was a significant positive correlation between yield and organic matter，total nitrogen and available phosphorus，and a significant negative correlation with pH.It was concluded that the combined application of organic fertilizer，straw return and chemical fertilizer could significantly improve soil fertility and thus increase crop yield.The research results could provide a scientific basis for the improvement and utilization of salinized arable land and the comprehensive utilization of straw in the West Liaohe Plain.
