摘　　要：通过淡水洗盐、有机质增效和提高渗透性方法,对港城原土进行了快速改良研究。结果表明:通过淡水洗盐均可将不同含盐量土壤的盐分洗至正常水平(0.2%)以下,加水量(Y)与土壤含盐量(X)的直线回归方程为Y=1.455 2+0.597 0X(R2=0.934 5);添加玉米秸秆可明显提高土壤有机质含量,且随添加比例的增加而提高;添加玉米秸秆和珍珠岩可提高土壤渗透性,添加比例以5%为宜。The rapid improvement techniques of alkali saline soil were studied using washing salt with fresh water, increasing organic matter content, and improving soil permeability. The results showed that the soil salt content decreased below normal level （0. 2% ） by washing salt with fresh water. The linear regression equation between the soil salt content （X） and the volume of fresh water （Y） was that Y = 1. 455 2 ＋ 0. 5970X （R^2 = 0. 934 5 ） ; The soil organic matter content increased obviously by adding corn stalk, which increased with the increasing of corn stalk. The soil permeability increased by adding corn stalk and perlite, and the appropriate ratio was 5 %.
