摘要
将三种不同处理的污泥(脱水污泥、腐熟污泥和冻融污泥)分别与煤矸石、粉煤灰和土壤配制成不同复混基质用于矸石山复垦,进行了基质理化性质的分析以及沙生冰草[Agropyron desertorum(Fisch.)Schult.]和无芒雀麦(Bromus inermis Leyss.)两种禾本科植物的种植试验。结果表明:无土复混基质B2(腐熟污泥:煤矸石:粉煤灰配比分别为30:60:10:0)的理化性质优于其余基质,更有利于植株生长,又能节约成本。
Compound-mixed substrates consisted of different treated sludge(dewatered sludge、compost sludge or freeze-thaw sludge), coal gangue, fly ash and soil were used for coal gangue mountain reclamation. The physical and chemical properties were analyzed and cultivation experiment of two kinds of gramineous plants including Agropyron desertorum(Fisch.) Schult. and Bromus inermis Leyss. was implemented. The results showed that the physical and chemical properties of compound-mixed substrate B2(the quality ratio of compost sludge, coal gangue, fly ash and soil was 30:60:10:0) were better than other substrates, and were more beneficial to the growth of plants, and saved cost.
