摘要
为恢复冶炼厂周边工业废气污染山地的植被,采用包括增施不同量石灰粉、不同的整地措施、筛选抗污染造林树种等技术措施进行试验。结果表明:施石灰粉调节植穴土壤pH值能显著提高造林成活率;开水平带显著降低造林成活率;以造林成活率为主要筛选指标,适合在冶炼厂周边工业废气污染山地推广种植的6个树种为夹竹桃(Nerium indicum)、铁冬青(Ilex rotunda)、樟(Cinnamomum camphora)、无患子(Sapindus mukorossi)、木荷(Schima superba)、山杜英(Elaeocarpus sylvestris)。
In order to recover vegetation on industrial polluted mountain,afforestation experiments were carried out in Meizhou,Guangdong.The treatment included adding lime powder in soil and different tillage measures.15 tree species were chosen in afforestation.The results were as following：adding lime powder could significantly increase survival rate of afforestation by adjusting soil pH value.Horizontal belt tillage would significantly reduce survival rate of afforestation.Based on the growth characteristics and survival rate,6 tree species,including Nerium indicum,Ilex rotunda,Cinnamomum camphora,Sapindus mukorossi,Schima superba and Elaeocarpus sylvestris,were suitable in industrial polluted mountainous area in Meizhou.
