南方雨水多导致土壤偏酸和电导率低，原生土一般不可直接用作园林种植土。如何提高土壤的 pH 值与电导率，成为南方园林绿化工作者的重要课题。广州市生态景观林带项目——广河高速凤凰山隧道绿化工程采用增施无机肥的方法来改良种植土，是改良南方酸性种植土电导率低的有益尝试。

In the rainy south China, the native soil is generally not qualified to be used as garden planting soil because of its acidity and low conductivity. How to raise its pH value and conductivity has become an important subject for the South greening and gardening researchers. This paper based on the greening engineering of Fenghuangshan Tunnel of Guanghe Freeway, used inorganic fertilizer to improve the soil, achieving satisfactory effect, and thus finding a method to enhance the conductivity of the acid soil in the south.
