添加VT菌剂和有机物料腐熟剂对堆肥的影响

Effect of inoculating VT microbes and organic matter-decomposing inoculant on high-temperature aerobic composting

通过在高温好氧堆肥中分别添加VT菌剂和有机物料腐熟剂,研究接种3‰的VT菌剂和有机物料腐熟剂促进堆肥的作用效果。结果表明,接种VT菌剂的处理与空白和接种有机物料腐熟剂的处理相比,堆肥初期升温更快;高温期更长;堆肥结束时,C/N降低的多,NO3-N增加的多,NH4+-N挥发的少,接种VT菌剂和VT有机物料腐熟剂都可促进有机质的充分降解,缩短堆肥时间,加快堆肥腐熟,提高堆肥肥力。

This paper aims to discuss the effect of VT microbes and VT organic substance decompostion maturing microbes on high-temperature aerobic composting by respectively inoculating 3%v VT microbes and organic substance decompostion maturing microbes. Results show that inoculating VT microbes led to faster temperature rising and prolonged high temperature stage; and lower C/N ratio, higher NO3-N concentration, less lose of NH4＋ -N at the end of composting. Inoculating either VT microbes or VT organic substance decompostion maturing microbes can promote decomposing of organic matter, shorten composting period and enhance composting fertility.
