摘要：This paper explores 9 different composting schemes to determine the optimal strategy to improve thecompost maturity of municipal solid waste. The second-time compost, in the volume ratios of 0%, 25%,50%, 75%, 100%, was used to plant Amorpha fruticosa and Festuca arundinacea. We measuredemergence time and plant growth to determine the effect of the compost on the growth of Amorphafruticosa and Festuca arundinacea. After fuzzy analysis, we found that maturity of T5 and T6 is thebest, and compost maturity was optimal resulting from the process with no additional water, addingagents every 9 days, and turning every 3 days with an initial C/N of 20. The main factors affecting thedegree of maturity are the initial C/N, followed by water situation, inoculated case, and turning frequency.The second-time compost allows reduction of soil heavy metal content and is conducive to Amorphafruticosa survival and Festuca arundinacea germination. However, the high adding proportion ofsecond-time compost delays the survival and emergence time, and also makes higher stems root ratioof Festuca arundinacea. The 50% and 75% proportion has higher seedling height and ground diametergrowth of Amorpha fruticosa. The seedling height of Festuca arundinacea is better in the 75%proportion.
