天津滨海新区盐碱土绿化综合治理技术研究

Comprehensive Improvement Method of Saline Soil for Urban Greening in Tianjin Binhai New Area

论述了天津滨海新区自然条件与土壤盐碱化关系,当前滨海新区城市绿化盐碱土综合治理模式与技术,并提出了今后滨海新区盐碱土治理研究重点和方向。当前滨海新区盐碱土治理模式以"抬"为基础,以"排"为核心,并辅助农业措施、物理化学措施和生物措施;主要技术方法包括土方填垫、暗管排水、翻土晒垡、施肥整地、客土改良、盐生植物改土、绿肥改土、耐盐碱园林植物改土等。

The paper discussed the relationship between natural conditions and soil salinization, comprehensive improvement mode and methods of saline soil for urban greening in Tianjin Binhai New Area, and proposed the key studies on improvement of saline soil for urban greening on next step. The current improvement model of saline soil made ground elevation as the basis, took drainage as the core, and integrated agricultural practices, physical and chemical measures, and biological measures. The main methods included filling earthwork, subsurface drainage, turning and exposing soil, organic fertilizer application and soil tillage, soil improvement by soil exchange, planting halophytes, planting green manure, and planting salt-tolerant garden plants.
