高寒地区盐碱化公路边坡绿化是一个尚未很好解决的技术难题。黑龙江省西北部有许多盐碱化地区公路绿化难度大,多年来一直没有很好的绿化手段。经人工培育的菊芋具有栽培简单、施工成本低、绿化效果好等优点。在黑龙江省道林肇线杜蒙段的工程实践中取得了理想的绿化效果,对本地区其他盐碱路段的边坡绿化具有示范意义。
Alpine region salinization of road slope greening is not yet a good solution to the technical problems. There are many roads in the northwestern part of Heilongjiang Province where salinization is difficult to green, and there has been no good means of afforestation for many years. The artificially cultivated Jerusalem artichoke has the advantages of simple cultivation, low construction cost and good greening effect. The ideal greening effect has been obtained in the engineering practice of Dumont section of Daolin-Zhaoqing line in Heilongjiang Province, demonstrating the significance of slope greening in other salty-alkaline sections in this area.
