Abstract:
Composting is an environmentally friendly and effective way to dispose of green waste (GW), but traditional composting of GW is slow and results in the loss of many nutrients and a poor-quality compost product. In this study, mature compost (MC), which may function as an inexpensive and readily available microbial inoculant, was added to GW at 15, 20, 25, and 30% (w/w, dry weight basis) (treatments T2-T5, respectively); GW with 0.5% (v/w, dry weight basis) commercial microbial inoculum served as T1, and GW without any microbial inoculant served as the control. The treatment that produced the highest quality compost was determined based on the following compost properties: temperature, bulk density, porosity, pH, electric conductivity, contents of organic matter and nutrients, Fourier-transform infrared spectroscopy data, and phytotoxicity. The results showed that addition of 25% MC resulted in the best quality product in only 40 days.
摘要:
堆肥是一种环保而有效的处理绿色废物(GW)的方法,但是GW的传统堆肥速度很慢,会导致许多营养素的损失和劣质堆肥产品。在这项研究中,成熟堆肥(MC),它可以作为廉价和容易获得的微生物接种剂,以15%、20%、25%和30%(w/w,干重基础)(处理分别为T2-T5);GW为0.5%(v/w,干重)商业微生物接种物用作T1,没有任何微生物接种物的GW用作对照。根据以下堆肥特性确定产生最高质量堆肥的处理:温度,堆积密度,孔隙度,pH值,电导率,有机物和营养物质的含量,傅里叶变换红外光谱数据,和植物毒性。结果表明,添加25%MC仅在40天内就获得了最佳质量的产品。
