摘　　要：以风干污泥、豆秸和细沙按比例混合作为草坪基质进行试验,分析污泥组配基质对草坪草种子萌发和初期生长的影响。结果表明,风干污泥组配基质对草坪草的生长起到了一定的促进作用。与纯污泥基质相比,基质中含有豆秸有助于草坪草根系生长,而基质中添加细沙有利于草坪草萌发和地上生物量的积累。A pot experiment was conducted using air-dried sewage sludge, haulm and sand as turf medium to investigate the effects of compound medium on seed germination and seedling growth of two turfgrasses.The results indicated that compound medium with air-dried sewage sludge promoted turfgrass growth. Compared with the control （100% sludge）, the addition of haulm in compound medium may contribute to root growth. However, the addition of haulm in compound medium may contribute to seed germination and accumulation of aboveground biomass.
