在接种和未接种条件下,研究了一种菌剂YD-KF1对堆肥制作效果。结果发现,接种该菌剂加快堆肥升温速度、提高最高温度、延长高温维持时间;堆肥制作的升温期和高温期,接种菌剂分别促进了淀粉、可溶性糖和粗纤维等物质的降解,加快了堆肥的腐熟进程。采用PCR-DGGE方法,分析该菌剂对堆肥制作不同阶段微生物群落的影响,发现在堆肥制作升温期和未接种处理相比,接种菌剂的处理微生物群落发生了明显的变化。结果表明,该菌剂通过调整堆肥制作前期的微生物群落,加快堆肥进程,在堆肥制作中表现出良好应用前景。
Under inoculation and non-inoculation conditions, the effect of YD-KF1, a fungicide, on compost production was studied. The results showed that inoculation of the fungicide accelerates the compost heating rate, increases the maximum temperature and prolongs the maintenance time of high temperature. The inoculation agents promote the degradation of starch, soluble sugar and crude fiber, respectively, at the elevated temperature and high temperature, Composting process of maturity. The PCR-DGGE method was used to analyze the effect of the agent on the microbial community at different stages of compost production. It was found that the microbial community inoculated with inoculant significantly changed compared with the non-inoculation treatment during the temperature-rising period of composting. The results showed that the fungicide showed a good application prospect in the compost production by adjusting the pre-microbial community in composting and accelerating the composting process.
