摘要
煤矸石是采煤过程中产生的固体废弃物,占用大量土地资源难以处置。以煤矸石为载体,将N、P、K和微量元素等载起可制作矿物肥料。通过田间试验、数学分析相结合的方法较系统地研究了矿物肥料对试验作物产量等的影响。结果表明矸石肥料可以增加经济效益和社会环境效益,减少大气和地下水的氮污染。
Coal gangue which is a kind of solid waste to be in coal mining process occupied a lot of lands resources and was difficult to be disposed. In this paper, coal gangue as an experimental carrier with N, P, K and other trace elements, was used as a mineral fertilizer. By field experiments and mathematic analysis, the effects of the mineral fertilizer on the yield of crop were systematically studied. The results showed that mineral fertilizer can reduce the air pollution and the nitrogen pollution of groundwater. And remarkable economic benefit, social benefit and environment protection benefit were obtained.
