摘　　要：以城市垃圾堆肥为主,添加不同比例的磷石膏组成基质,对4种常见的冷季型草坪草的生长状况及草坪质量进行了研究。结果表明:添加磷石膏的城市垃圾堆肥基质上多年生黑麦草和高羊茅获得良好的生长响应,草坪质量高,出苗、生长和成坪速度快,色泽和均一性好;匍匐翦股颖和草地早熟禾的长势和草坪质量较差。表明,添加磷石膏可促进多年生黑麦草和高羊茅的生长,提高草坪质量,但对匍匐翦股颖和草地早熟禾的促进作用较小。草坪质量综合评定得出,以添加磷石膏的城市垃圾堆肥为基质建植多年生黑麦草和高羊茅草坪是可行的,最适合的基质分别为90%城市垃圾堆肥与10%磷石膏和85%城市垃圾堆肥与15%磷石膏。Four lawn grass species with the cold season type were tested on the substrates of urban rubbish compositing manure with different phosphogypsum proportion to study the effect on grass growth and lawn quality. The results showed that the growth vigor, lawn quality, grass color and evenness of perennial ryegrass and tall feseue are better than creeping bent grass and annual bluegrass, which indicates that phosphogypsum can promote growth and lawn quality of perennial ryegrass and tall rescue. The comprehensive assessment results of lawn quality showed that it is feasible to culture the lawns of perennial ryegrass and tall fescue on the substrate of urban rubbish compositing manure with phosphogypsum and the optimum formulation substrate is 90% urban rubbish compositing manure and 10% phosphogypsum or 85% urban rubbish compositing manure and 15% phosphogypsum.
