| 摘 要： | 自燃煤矸石山渣土具有高盐强酸性,严重制约了植物的生长,因此在对自燃煤矸石山进行植被恢复时,首先要对煤矸石山渣土进行改良。以研究区内黄土作为改良剂,研究了其对自燃煤矸石渣土的改良方法和效果。选取高羊茅、刺槐、紫穗槐、侧柏、山皂角在改良后的渣土中进行种植实验,测试改良效果,筛选适宜在煤矸石山上种植的植物,并确定黄土作为改良剂的施用比例。改良实验结果表明,黄土作为改良剂对自燃煤矸石渣土的强酸性改良效果良好,在pH值为2.8的强酸性渣土中,加入25%的黄土,pH值可提高到6.8。对自燃煤矸石渣土的高盐性改良效果较差,在盐分为3.8%的煤矸石渣土中,加入62.5%的黄土,盐分可降低至0.97%。种植实验也表明,高羊茅、紫穗槐、山皂角对改良后煤矸石渣土的适应性较强,刺槐、侧柏的适应性则较弱。

| Abstract: | Due to its attribute such as high salt and strong acid,the mountainous gangue which had undergone spontaneous combustion seriously constrains plant growth.Therefore it is imperative for ameliorating the conditions of gangue mountain to restore vegetation.The abundant and cheap loess was selected as ameliorant,then the ameliorative effect of the diverse ameliorated methods on Festuca elata,Robinia pseudoacacia,Amorpha fruiticosa,Platycladus orientalis and Gleditsia horrida respectively in the mixed gangue an... |
