根据土壤分布在河流入海平原处及土壤含盐量０２％～０３％、ｐＨ８５～１００、碱化度５０％～６０％、总碱度０８～１０、总碱度占阴离子之和的４０％左右等指标，确定滨海苏打盐渍土。改良该土壤的有效措施是修台田后整地、压稻乱、覆山皮土、压沙及种植沙枣和绿肥植物。改良后的苏打盐渍土选择造林树种的顺序：沙枣、小胡杨、群众杨、绒毛白蜡。 According to the soil distribution in the rivers into the sea plain and the soil salinity 0  2% ~ 0  3%, pH 8  5 ~ 10  0, alkalinity 50% ~ 60%, total alkalinity 0  8 ~ 1  0 , Total alkalinity accounted for about 40% of the sum of anions and other indicators to determine the coastal soda saline soil. Effective measures to improve the soil is to repair the field after land preparation, pressure rice chaos, cover the mountain earth, sand and planting sand date and green manure plants. Improved sodic saline soil selection afforestation tree order: jujube, Populus euphratica, poplar, fluff white wax.
