摘    要:采用在塑料大棚内堆制方法,研究了不同工艺条件和不同调理剂的猪粪高温堆肥的影响。结果表明,原工艺堆肥初期温度上升缓慢,堆体中微生物长时间不能达到合适的生长温度,使发酵效率降低,发酵时间明显延长,同时,原工艺堆体散发出的氨味非常浓,导致肥料产品营养成分散失严重;而改进工艺堆肥升温快,微生物生长繁殖迅速,从而有效地缩短了发酵时间,堆肥物料有淡淡的氨味和酵香味;新鲜猪粪中加入锯末、干猪粪及蘑菇渣作为调理剂,调节初始物料含水率至65%左右,并接入合适的微生物菌剂有利于猪粪发酵腐熟;干猪粪和蘑菇渣作为调理剂具有相似的效果,但干猪粪容易获得,并且处理氮的转化率更高,更适合作为堆肥调理剂。

关 键 词:猪粪  堆肥  工艺  调理剂

Abstract:Effect of different technics and bulking agents on composting of swine f e ces was studied.Under the primary t echnic,the temperature during initial phas e rised so slowly that the composting cou ld not reach the suitable temperatur e for microorganismgrowth for a long time,which caused reducin g the fermentatio n efficiency and pr olonging the fermentation time obviously.At the same time, the odor of ammonia resulted from the composting under the primary techni cs was very thick,which caused dissipating of product nutrition seriously.Under the impr oved technics,the temperature went up rapidly,the microorganisms in co mp osting grewso quickly that the fermentation time was shortened efficiently,and the compostin g materiel had light ammonia odor wit h a little ferment fra-gran ce.Adding sawdust,dry feces an d mushroom dregs in fresh swine feces,regulati ng the initial water conte nt around 65%,and inoculating suitable bacterial pre paration were in favor of the maturity of composting.Dry feces and mushro o m dregs had the similar effects in fermentation,but the former,with higher tra nslating rate of nitrogen and obtaining easily,was m ore suitable for compostin g bulking agent than the latter since.
Keywords:swine feces  composting  techn ics  bulking agent
