在我国农村,利用人畜粪便、作物稿秆等有机物制取沼气,提供生活能源,已收到显著成效。而发酵残留物作为肥料再利用,其培肥改士效果如何?则是人所关心的问题。近年来,国内研究者,对于沼气肥的性质和肥效,有不少研究报道。但是,对于沼气发酵残渣(下简称沼渣)改良土壤、培肥地力的作用,研究还不多。作者 In China’s rural areas, the use of man and animal manure, crop draft stalks and other organic matter produced biogas, to provide energy for life, has received significant results. The fermentation residue as a fertilizer reuse, the effect of fertilizers to change how? It is a matter of concern. In recent years, many domestic researchers have reported on the nature and efficiency of biogas fertilizer. However, there is not much research on the role of biogas fermentation residue (hereinafter referred to as biogas residue) in soil improvement and soil fertility improvement. Author
