摘要

有机废物改性粉煤灰的蚯蚓复合是一种有效的生物技术，可以降解这种作为植物营养物质来源的废物。本研究试图确定这种生物转化的最佳水分状态。有机废物混合粉煤灰在不同水分条件下的蚯蚓堆肥显示出微生物活性的提高以及堆肥的不同指标，基质的水分状态提高到50-55%。紧随其后的是40-45%的湿度范围。通过三种主要植物营养素的可用性评估，该产品的质量也被发现在这些水分条件下优越。建议保持40-55%的湿度范围，以促进有机废物改良粉煤灰的最佳蚯蚓堆肥。

Effect of Moisture Status on Vermicomposting of Organic Waste Amended Fly Ash

Vermicomposting of organic waste amended fly ash has lately emerged as an effective biotechnology for degrading this waste material as source of plant nutrients. Present study attempted to determine the optimum moisture status for such bio-conversion. Vermicomposting of organic waste mixed fly ash under different moisture regimes showed improvement in microbial activity well as different indicators of composting with increase in moisture status of the substrate up to 50-55% moisture content. This was closely followed by 40-45% moisture range. The quality of the product, as assessed by availability of three major plant nutrients, was also found to be superior under these moisture regimes. Maintenance of 40-55% moisture range for facilitating optimum vermicomposting of organic waste amended fly ash has been suggested.
