Abstract:The distribution,type,and salt characteristics of inland saline soil in the Hexi corridor were analyzed.Experiments of bioremediation and control were conducted with the alkali meadow grass planted in saline soil for 3 years.Contrasted with control group,topsoil desalination rate was up to 77.00%;pH value decreased 0.25 pH unit;soil bulk density decreased 0.14 g/m3;total porosity increased by 5.29%;soil aggregate structure increased by 23.14%;soil water content increased 70.30 g/kg;average triennial alkali grass yield was 36 000 kg/hm2(fresh weight).In addition,planting forage in saline soil as a medium and establishing a compound agro-forestry-animal system promoted the sound combination of planting industry,forestry,and livestock husbandry.Because of the reasons,utilization ratio of land reached more than 184.00%;the income of land increased from 16 300 to 35 500 yuan/hm2;average income per farmer in the controlling region increased by 66.00%,from 2 160.70 to 1300.80 yuan.
