公路绿化工程立体复合种植技术分析

Analysis on planting technology of highway greening landfill

结合工程实例,通过分析种植绿化的种植工序、种植模式、种植物配置、种植方式、主要事项、技术要求,分析研究表明,种植前须对回填土进行改良,提高土体渗水率和通气性,补充土体营养成分,改善土体理化性状,从而提高土壤保肥程度、透水程度、通气程度,达到有利于植物根系生长扩展的目的。

Through the analysis of the growing process of planting afforestation,planting patterns,plant configuration,technical requirements,planting method,the main items,analysis showed that must be modified to backfill soil before planting,improve soil water penetration rate and air permeability,replenish the soil nutrients,improve soil physical and chemical properties,thus improve the degree of soil protecting fertilizer level,the degree of water,ventilation,achieve the goal of conducive to plant root growth extension.
