我省由于冬季气候严寒,土壤有机物分解慢,粪堆冻结,发酵粪肥时多采用柴烧,不仅发酵粪肥时间长,而且不易发透,影响肥效,达不到无害化的目的。同时,每年春季送粪时,又要花费大量劳力刨粪。为此,我县贫下中农和科技人员组成试验小组,开展了应用黑曲霉发酵粪肥的试验,经多次试验,终于取得了黑曲霉冬季发酵粪肥的成功。现已在本省一些地区推广使用。
Due to the cold winter climate in our province, soil organic matter decomposition slow, fecal pile freezing, fermentation of manure used more firewood, not only fermented manure for a long time, but not easy to penetrate, affecting fertilizer efficiency, reach the goal of harmless. At the same time, it takes a lot of labor to dig manure when sending feces in spring each year. To this end, the poor and middle peasants in our county and scientific and technological personnel to form a test group to carry out the application of manure fermentation Aspergillus niger, after many tests, finally made the success of Aspergillus niger winter fermented manure. Now some areas in the province to promote the use.
