摘　　要：围绕煤矸石缺乏有机活性物质及有效养分的问题，在矸石山复垦种植时，对施肥作了试验研究。结果表明，煤矸石风化物由于吸附性能低，保肥性差，所以施用化肥时一次用量不宜过大。并从降低复垦的投资与难度以及尽快建立一个可自我维持生长的植被出发，提出了矸石山复垦种植时化肥与污泥配合施用的施肥策略，并对污泥的施用效果做了研究。This paper studies the fertilization of gangue weathering matter centered around its serious deficiencies in organic active matter and available nutrients. The results showed that application rate of each time should not be high because of its low absorbability and low fertility preserving capability. Proceed from reducing investment and difficulties in reclamation and quick establishment of a self maintaining vegetation, the paper advances a fertilization strategy of combining chemical fertilizer with sludge, and studies the fertilization effect of sludge.
