摘要
施用污泥堆肥后，黑麦草、紫羊茅、匍茎剪股颖、马尼拉草和白三叶都获得了良好的生长响应。它们的生物量增加，绿色期延长，土壤理化性质有明显改善。长期施用该堆肥，不会造成镉、汞对草坪草的伤害，当污泥堆肥施用量小于９ｋｇ／ｍ２时。
With the application of sewage sludge compost to ryegrass, red fescue, bentgrass, white clover and manila grass, good responses were observed among them, including increased biomass, prolonged turf green period and improved physical and chemical properties of the soil. It was shown that the application was safe, without damages on these turfgrasses caused by Cd and Hg from the compost; and when the application was less than 9 kilograms per square metre, there were no pollution problems related to nitrates through leaching and runoff.
