好氧堆肥阶段对蚯蚓堆肥的影响

Effects of Aerobic Composting Periods on Earthworm Composting

好氧堆肥和蚯蚓堆肥相结合处理有机废弃物能够获得更好的堆肥产品。不同好氧堆肥阶段堆肥产品质量和性质差别很大,这必然将影响蚯蚓堆肥产品稳定性和质量。对此,将好氧堆肥与蚯蚓堆肥相结合,以能够指示堆肥产品质量和腐熟度的碳氮比(C/N)、胡敏酸比富里酸(HA/FA)和胡敏酸的E4/E6三个指标构建新的指标体系,对蚯蚓堆肥产品质量进行评价。并且在此指标体系基础上,得出将好氧堆肥高温期阶段作为蚯蚓堆肥的前期处理可以获得更加稳定和高品质的蚯蚓堆肥产品。

Combining aerobic composting with earthworm composting to treat organic waste can get a better corn- posting product. The quality and nature of composting product greatly vary in different stages of aerobic compost, which will inevitably affect the stability and quality of earthworm composting product. For this problem, we com- bined aerobic composting with earthworm composting, and then we used three indicators ： carbon-nitrogen ratio （ C/ N）, HA/FA and E4/E6 to build a new index system to evaluate the quality of earthworm composting product. Based on this index system, we find that using the high temperature period of aerobic composting as a pre-treatment of earthworm composting can get more stable and high-quality composting products.
