【摘要】 通过在园林废弃物堆肥中添加不同比例污泥进行混合堆肥实验,研究堆肥过程中温度、pH值等指标变化情况,探究堆肥产物应用于绿化行业的可行性。研究发现:园林废弃物堆肥中添加一定量的污泥,能优化堆肥环境,堆肥效果较好;比例适宜的混合堆肥表现出升温速度、高温期时间、腐熟效率、安全性等方面具有一定优势;目前我国园林废弃物资源化比例较低,混合堆肥产物可作为土壤改良基质进行土地利用,实现资源化利用,促进园林绿化产业发展。更多还原

【Abstract】 In order to solve the increasing problem of garden wastes year by year, the different proportion mixing compost experiments in garden wastes and sludge are conducted to study the changes of temperature and PH targets in the garden waste composting process and the feasibility of compost products applied in greening industry. The result shows that a certain quantitative sludge in the garden wastes compost can optimize the compost conditions and achieve the better compost result. The proportion appropriate mixing composts have the advantages of warming speed, high temperature period, rotten efficiency and high security. At the present, the resource proportions of garden wastes in our country are relatively lower. The garden wastes can use the mixing compost products as a sample of soil ameliorations to carry out the land use and realize the utilization of resource and promote the development of garden greening industry.更多还原
