摘要/Abstract

摘要： 经过63d堆肥化处理后,猪粪与木屑混合堆肥及猪粪、木屑与树叶混合堆肥的T-N分别从开始的1.57%和1.78%增加到2.0%和2.11%;水溶性NO₃-N/水溶性T-N均从接近于0的水平增加到3%左右;水溶性有机N/水溶性T-N分别增加到70%和76%;水溶性NH4N/水溶性T-N则分别从开始的52%和61%下降至堆肥结束时的30%和24%.种子发芽系数的测定结果表明,加入树叶有利于猪粪的腐熟化,可使猪粪堆肥化处理所需的时间从42d缩短至35d.化学指标与种子发芽系数的相关分析结果表明,水溶性NH4N/水溶性T-N、水溶性NO₃-N/水溶性T-N和水溶性有机N/水溶性T-N均与种子发芽系数呈显著相关,可作为堆肥的腐熟度评价指标.

Abstract: The contents of T-N, the ratios of soluble NO₃-N/soluble T-N and soluble organic N/soluble T-N increased after co composting for 63 days of pig manure and sawdust with or without additional leaves, while the ratios of soluble NH₄-N/soluble T-N decreased. In this study, addition of leaves was beneficial for maturation of pig manure composting, and it could shorten the composting time from 42d to 35d.The ratios of soluble NH₄-N/soluble T-N,soluble NO₃-N/soluble T-N and soluble organic N/soluble T-N correlated with seed germination index (GI) significantly, and it could be used for maturity evaluation.
