盐碱地公园绿化树种的选择

Study on the Choice of Virescence Trees in Saline-alkali Land Park

为更好地指导大庆市及采油七厂公园盐碱地的绿化,在规划地土壤表层化学性质测定的基础上,参照不同树木耐盐能力上限,分别对全盐量在0.1%～0.3%、0.3%～0.5%、0.5%～0.7%、>0.7%的131个样点上绿化树种的生长状况进行了调查及分析,并进而给出了树种选择及绿化工作的建议。

In order to instruct the afforestation in Daqing city and saline-alkali land park of the No. 7 Oil Production Company, growth conditions of afforestation trees in 131 soil point with different soil soluble salt of 0.1%-0.3%, 0.3%-0.5%, 0.5%-0.7% and 〉0.7% were investigated and analyzed based on chemical properties mensuration of the plan land soil in different surface layer and referred to different stalt-resistance upper limit of trees.
