以废弃烟末和腐殖土为主要原料进行高温堆肥试验，在添加不同有机物料腐熟剂的条件下，采用好氧人工翻堆方式，研究了烟末＋腐殖土高温堆肥进程中有机碳、全氮、 C／N和T值〔（初始C／N）／（堆肥后C／N）〕的变化规律。结果表明，堆肥33天后，添加BYM菌和VT菌的堆料中有机碳的下降率比不添加腐熟剂的分别提高了49．72％、26．41％；与堆肥前相比，不添加腐熟剂的全氮含量降低了10．50％，而添加BYM菌和VT菌全氮含量增加了27．69％、43．84％，添加腐熟剂处理的C／N值小于20、 T值小于0．6，达到完全腐熟。由此可得出，添加腐熟剂加快了烟末－腐殖土联合堆肥过程中有机碳的下降速度和比例，增加了全氮含量，降低了腐熟后堆料的C／N和T值。

Using tobacco waste and humus soil as the basic raw material , adding different microbial inoculants , the change of organic carbon , total nitrogen , C/N and T value with the proceeding of aerobic composting was studied . The study results showed that 33 days after composting , the decrease ratio of organic carbon of the substrate using BYM and VT were respectively 49.72%and 26.41%higher than the control without adding microbial inoculants . After aerobic composting , the total nitrogen content of the control decreased by 10.50%, on the contrary , through adding BYM and VT , the total nitrogen contents increased by 27.69 % and 43.84 % respectively . Through adding microbial inoculants , the C/N of the substrate was lower than 20, and the T value was lower than 0.6, indi-cated the substrate was sufficiently composted .However , without adding microbial inoculants , the C/N and the T value of the substrate were still higher than 20 and 0.6 respectively.It was concluded that , during the aerobic com-posting of the mixed materials of tobacco powder and humus soil , microbial inoculants accelerated the decreasing of organic carbon , increased the content of total nitrogen , and decreased the C/N and T value .
