盐碱地绿化技术研究--以宁波北仑区为例

The Research on Saline and Alkaline Land Greening Technology—Beilun of Ningbo as an Example

通过调查及大量的文献查阅,分析了盐碱地的类型及其形成的原因,总结了盐碱地常用的绿化种植技术——化学改良措施、生物改良、铺设地下管网滤水排盐、灌溉与排水结合、平整土地、铺设隔离层、铺设地膜、抬高地面,并结合工程案例,具体从土壤改良、植物选择、树种种植等方面分析了提高滨海盐碱地绿化种植的技术措施,为今后滨海盐碱地的绿化奠定基础。

Through investigation and consulting literature materials,this paper analyzes the types of saline-alkali land and their formation causes,summarizes the common afforestation planting technology of saline and alkaline land — chemical improvement measures,biological improvement,laying underground pipe network to filter water salt,irrigation and drainage combination,flat land,laid isolation layer,laying mulch,driving up the ground.Combined with the company＇s project cases,the paper especially analyzed technical measures of improving coastal saline—alkaline land greening plant from soil improvement,plant selection,planting tree species,which lays the foundation for future greening of coastal saline-alkali land.
