酸性土壤矿区复垦中护坡植被品种筛选研究

Study on selection of slope protection plantation varieties in acid soil mine area reclamation

平果铝土矿土壤材料主要由贫瘠的矿床底板粘土构成 ,质地酸、重、粘 ,植被条件差 ,我们通过实验室盆栽与田间小区试验 ,进行了边坡地植被品种筛选 ,得到了一批具有抗逆性强、速生能力好、根系发达、网络性好的植被品种。

In view of such characteristics as the soil formed mainly by clay of poor ore deposit floor, the acid, heavy and sticky quality and poor plantation condition in Pingguo aluminum mine, and through laboratory pot culture and field experiment, the plantation varieties at the slope area are selected, and a batch of plantation varieties are obtained which have strong antireverse ability, quick growing ability, developed root system and good network. The research method of plantation varieties selection and the experiment result are emphatically introduced in the paper.
