【摘要】:為探討縮短城市沼渣堆肥時間,提高堆肥效率和沼渣施肥技術(shù),采用二步法對好氧堆肥工藝進(jìn)行物料配比中試試驗,開展毛豆種植的沼渣施肥試驗.研究結(jié)果表明:調(diào)理劑菇土、稻殼、木屑可以促進(jìn)堆肥效率;堆體初期24h,它們比對照組的溫度分別提高8,5,3℃,產(chǎn)品水的質(zhì)量分?jǐn)?shù)分別減少45%,38%,14%,種子發(fā)芽率指數(shù)分別提高10%,8%,7%,產(chǎn)品粒度分別減少54%,34%,20%;毛豆種植配施沼渣有機(jī)肥與對照施肥比較,產(chǎn)量增加9.4%,土壤滲漏水硝態(tài)氮、總磷質(zhì)量濃度分別減少13.4%,21.6%,配施沼渣有機(jī)肥有利于毛豆增產(chǎn)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,
