Abstract: According to the exit soil problems about bad soil structure, nutrient deficiency and desalting alkalization on coastal saline soil, the experiments were carried out on improving saline soil by using soil amendments. The pot experiment was selected the best amendment by synthetically analyzing the soil salt content, soil nutrients content and growth of regrass. The field application effect showed that the amendments could prevent desalting alkalization and improve soil nutrient content, soil structure and soil fertilizer. Soil alkaline hydrolytic nitrogen, available phosphorus, available potassium, organic matter were individually increased 123.8%, 171.0%, 22.0%, 37.5%. Soil bulk density was reduced 15.54%, soil porosity and soil infiltration were increased 19.66%, 127.78%. Soil microstructure was produced the transition from plane voids to complex packing voids. Using amendments was good to adjust water, fertilizer, air and heat, it was suitable soil amendment on coastal saline soil.
