[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7 d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。
[Objective] The research aimed to study the influence of fermentation conditions on manure fermentation. [Method] The effects of fermentation time, fermentation season and the amount of compound bactericide on the fermentation efficiency of manure in pig farms were studied. Through crop cultivation experiments, and compared with chemical fertilizers and biogas slurry to verify the manure fertilizer efficiency. [Result] The fermentation time of manure was about 7 d, and the content of fertilizing element reached the maximum value. The fermenting effect in summer was better, and the content of ammonium nitrogen and nitrate nitrogen in manure increased most significantly. Adding compound fungicide to manure could help Fermentation. Pig manure and fertilizer farms have a considerable effect. [Conclusion] The fermentation time, fermentation season and compound bacteria agent could affect the fertilizer efficiency of manure fermentation in pig farms and should be paid attention to in the production.
