摘　　要：对不同菌种组合的4组有机肥料发酵菌剂进行筛选的结果表明,筛选出的4号菌剂接种于农业废弃物与对照相比,堆肥初期达到高温期的时间缩短4d,堆肥发酵周期缩短38d,成品有机肥的微生物群体数量增加6.55亿个/g,同时成品肥中N、P、K养分含量比其它菌剂处理的成品肥平均提高11.33%,3.11%,16.12%。Four different combinations of fermentation inoculia were sele ct ed in the agricultural syn-thetic manure.The result showed when inoculum No. 4was inoculated in the manure,the time reach-ing to the high temperature was shorter than ck;the fermentation period was shortened38days;the number of m icroorganisms was increased by6.55×108/g.The contents of N,P,K in th e finished ma-nure were higher11.33%,3.11%and16.12%respective ly than that in the manures treated by other inoculia.
