Method for controlling stony desertification through watercourse sludge

一种利用河道淤泥治理石漠化的方法

Abstract

本发明公开了一种利用河道淤泥治理石漠化的方法,该方法是在河道淤泥中加入粉煤灰,混合均匀,在室温环境放置5-10天,使其含水率达到45-70%,用模具制成球体,再将先锋植物的秧苗根系埋入球体中,均匀施放在石漠化地域。本发明的有益效果是:不仅解决了大量河道淤泥的处理问题和淤泥海洋抛泥或陆地填埋造成的环境污染问题,同时,还能解决因石漠化地区土壤贫瘠导致植物种植困难的问题,实现河道淤泥的资源化利用,既节约资源,又保护环境,具有良好的社会经济效益及广阔的应用前景。
The invention discloses a method for controlling stony desertification through watercourse sludge. The method includes the steps that coal ash is added to the watercourse sludge to be mixed evenly, the mixture is placed indoors for 5-10 days, the water content is made to reach 45-70%, the mixture is made to be balls through a mold, roots of seedlings of pioneer plants are buried in the balls, and the balls are evenly placed to the stony desertification areas. The method has the advantages that a large amount of watercourse sludge is processed, the problem that environmental pollution is caused when sludge is dumped to seas or used for land filling can be solved, the problem that plants are difficult to plant due to soil depletion of the stony desertification areas can also be solved, resource utilization of the watercourse sludge is achieved, resources are saved, the environment is protected, and good social and economic benefits and wide application prospects are achieved.
