【摘要】：为探讨缩短城市沼渣堆肥时间,提高堆肥效率和沼渣施肥技术,采用二步法对好氧堆肥工艺进行物料配比中试试验,开展毛豆种植的沼渣施肥试验.研究结果表明:调理剂菇土、稻壳、木屑可以促进堆肥效率;堆体初期24h,它们比对照组的温度分别提高8,5,3℃,产品水的质量分数分别减少45%,38%,14%,种子发芽率指数分别提高10%,8%,7%,产品粒度分别减少54%,34%,20%;毛豆种植配施沼渣有机肥与对照施肥比较,产量增加9.4%,土壤渗漏水硝态氮、总磷质量浓度分别减少13.4%,21.6%,配施沼渣有机肥有利于毛豆增产和降低菜田氮磷淋失.
[Abstract]:In order to shorten the composting time and improve the composting efficiency and the technology of biogas residue composting, a pilot experiment was carried out on the aerobic composting process by two-step method. The experiment of applying fertilizer from marsh dregs of soybean planting was carried out. The results showed that the composting efficiency could be promoted by the treatments of mushroom soil, rice husk and sawdust. At the beginning of 24 hours, the temperature of the stacks increased by 8 ~ 5 ~ 3 鈩，
