摘要
就煤矸石利用技术提出了一种新途径。试验中通过不同方法处理煤矸石,进行了油菜的育苗试验,统计分析表明经复合脱硫剂和碱液浸泡处理过的煤矸石,出苗率均在80%以上,幼苗根系活力、叶绿素含量、叶面积、光合速率等均大于土壤。结果表明:未经处理的煤矸石不能直接作为无土栽培的基质,而脱硫处理后就能够作为无土栽培基质被利用。
In this study, we come up with a new approach to utilizing the gangue as soilless culture substrate. The experiment wascarried out with the ganguetreated with different methods growing seedlingof rape plant(Brassica campestrisssp.chinensis (L.)Makino). The results showed that the germination rate of rape plants was more than 80% with the gangues treated with compound desulphurization and soaking in alkali liquid. And the root activity, Chlorophyll content, leaf areaand the photosynthesisrate of rape plant growing on the treated gangue were more excellent than that of the soil.
