摘要
以烟末为基本原料进行堆肥试验,在添加不同微生物腐熟剂条件下采用好氧人工翻堆堆肥方式,研究了烟末高温堆肥的腐熟进程。结果表明,添加福贝、定制、榕枫微生物腐熟剂缩短了烟末堆肥达到高温的时间,延长了高温分解持续时间,加快了堆肥pH值的增加和C/N比的下降,促进了氮的矿化和氨的减少,加快了烟末高温堆肥腐熟进程。添加微生物腐熟剂福贝、定制、榕枫的堆肥处理分别在堆肥7、14、15d后进入高温分解阶段(>50℃),持续高温时间分别为14、7和6d,而未加微生物腐熟剂的对照最高温度为45℃,未进入高温分解阶段。与纯烟末处理相比,添加微生物腐熟剂福贝、定制、榕枫的腐熟堆肥NO3--N含量分别提高了18.7%、12.2%、4.7%。添加微生物腐熟剂福贝的促进效果最佳。
Under an aerobic condition, high temperature composting using tobacco fine, an industry waste, as the basic material was carried out to study the effects of different microbial blends, Faby, Dingzhi and Rongfeng on composting process and maturity. The results showed that, adding the microbial blends shortened the time of reaching high temperature, extended high temperature sustaining time, accelerated pH increasing and the ratio of C/N reducing, increased N mineralization and ammonium decreasing, accelerated the decomposing process. The highest temperature was 45 ℃ in pure tobacco fine compost. The high temperature reaching time （〉50℃） in the composts adding Faby, Dingzhi and Rongfeng was 7, 14 and 15 d, respectively and the high temperature decomposing duration was 14, 7 and 6 d, respectively. The content of NOa-N was higher by 18.7%, 12.2% and 4.7% than that of pure tobacco fine compost, respectively. Microbial blend Faby showed better effects on high temperature compost maturity than other two microbial blends.
