摘要
在最适湿度、接种密度和20℃的室内培养条件下,以赤子爱胜蚓(Eiseniafoetida)处理未腐熟牛粪,蚯蚓堆制产物的多种生物学和化学指标及相关分析表明:种子发芽指数、脲酶活性、NH+4 N、NO-3 N/NH+4 N可作为反映蚯蚓堆制处理腐熟度的优选指标;NO-3 N、磷酸酶活性可作为一般性指标;蔗糖酶活性,水溶性碳、氮和挥发性固体不宜作为腐熟度的指标。
Maturity indices of vermicomposted cattle manure were studied in an optimal moisture condition at 20℃ and with inoculation of Eisenia foetida in laboratory.The variations of biological and chemical parameters of cattle manure during vermicomposting and their correlation coefficients indicated that GI,URE,NH^+_4-N and NO^-_3-N/NH^+_4-N were the priority selected maturity indices for vermicomposted cattle manure,NO^-_3-N and APH common ones,and INV,WSC,WSN and VS unsuitable maturity ones.
