Taking the copper accumulator plant Elsholtizia Sspledens as the raw material for composting,inoculated with the microorganism agent (mixed with cellulose utilization microorganisms and EMs),researches on different combination of microbes and environmental factors were conducted.Results indicated that during the composting period,water content of all the treatments descended dramatically.Total organic carbon decreased obviously,but total nitrogen concentration significantly increased.Mixed microbe agent paid much contribution to the quality of the product,making the C/N to 17.9.While concerning the outdoor temperature,75% water content treatment produced good compost,making the C/N to 13.7,and the η_C/N was about 60.8%,which met the standard of first level.Meanwhile,through the whole procedure,cellulose utilization microorganisms kept a vigorous ability to breakdown the cellulose,the microbe density sustained at nearly 2.79×10⁵ CFU/g (dry weight).By means of the effect of cooperation of microorganisms,the Elsholtizia spledens plant was composted quickly.
