Through the field experiment,the paper analyzed the influence of three different drip irrigations of 1350,1800 and 2250 m3/hm2 in spring on soil salinity variation.The experiment showed that in the same amount of irrigation,the effect of desalination for wide row is the best in the three different rows of wide,narrow and each film.Result showed that the amount of irrigation of 1800 m3/hm2 has the best salt leaching effect and can provide a reference for spring irrigation and has certain reference for the formulation of irrigation schedule.
