摘 要: | 为指导沼渣(液)的高效合理肥用,对4种不同类型原料沼气池沼渣沼液的养分情况做了分析,结果发现:以猪粪为原料的沼液中全P含量比其他原料沼液高出较多,而以秸秆为原料的沼气池,沼液中的氮含量偏低,而沼渣中的全N含量却较高;不同原料沼气池沼渣中有机质和腐殖酸含量差异不大;以玉米秸秆原料的沼渣生产有机肥时其粗纤维的降解问题需要引起重视。

Abstract: | In order to guide the using of anaerobic fermentation residue effectively, four kinds of anaerobic fermentation residues from different raw material were studied. The results indicated that total P content of biogas water-residue with pig-dung as raw material was much more higher than other treatments;total N content of biogas water-residue with maize-straw as raw material was lower and then total N content of biogas dreg-residue was higher than other treatments;the difference of biogas dreg-residue OM. and humus contents were not notable between all treatments; coarse fibre content of biogas dreg-residue with maize-straw as raw material was higher, how to degrade coarse fibre should be vital for producing fertilizer with that as raw material. |
