Abstract: The soil of Tianjin coastal saline alkali was treated with subcritical hydrolysis of municipal sludge, chicken manure, compound bacterial fertilizer and plant fiber binder. The results showed that using of subcritical hydrolysate（sludge+chicken manure） and mechanical construction technology could effectively promote plant growth, increase vegetation coverage, reduce soil pH and increase organic matter content in Tianjin coastal saline alkali.

Key words: soil conditioner, subcritical hydrolysis technology, municipal sludge, chicken manure
