摘要
[目的]研究发酵条件对粪肥发酵的影响。[方法]研究发酵时间、发酵季节、复合菌剂添加量对猪场粪肥发酵效果的影响。通过作物种植试验，并与化肥和沼液进行比较，验证猪场粪肥的肥效。[结果]粪肥发酵时间以7d左右较好，肥效元素含量可达最大值；夏季发酵效果较好，粪肥中铵态氮和硝态氮含量增幅最大；向粪肥中添加复合菌剂有助于发酵。猪场粪肥与化肥具有相当的肥效。[结论]发酵时间、发酵季节及复合菌剂可影响猪场粪肥发酵的肥效，在生产中应予以重视。
Abstract
Objective] To determine the effects of fermentation conditions on the pig manure fermentation.[Method] We researched the effects of fermentation time, fermentation season and compound bacteria additive dosage on the fermentation effects of pig manure.Crop planting test was carried out.It was compared with the fertilizer and biogas slurry so as to verify the fertilizer efficiency of pig farm.[ Result] The best manure fer-mentation time was around 7 days, and the fertilizer elements reached the maximum value;fermentation effect in summer was better, ammonium nitrogen and nitrate content in manure increased sharply;adding bacteria additive into the manure could contribute to fermentation.manure in pig farm and fertilizer had equal fertilizer efficiency.[Conclusion] Fermentation time, season and compound bacteria additive can affect the fertilizer effect of pig manure fermentation, so we should attach importance to them in production.
