畜禽废弃物的基质化处理试验采用木屑、茶渣和药渣为调理剂,分别配合0、20%、30%、40%质量比的猪粪,进行有机基质的腐熟对照实验.在整个腐熟周期,各组堆料的主要理化指标(堆温、pH值、电导率(EC)、有机质、全碳(TC)、全氮(TN)、全磷(TP)和总孔隙率等)随堆制时间呈现一定的变化规律.综合堆料的堆温变化、发酵周期和设施无土栽培对有机基质的理化指标要求,30%猪粪含量的腐熟后的有机基质,其理化性质比较适合作物栽培,腐熟周期适于工厂化生产.
Substrate treatment experiments of livestock and poultry waste Using woodchucks, tea dregs and dregs as conditioning agents, pig manure at 0, 20, 30 and 40% by mass respectively were subjected to maturity control experiment of organic substrate. Period, the main physical and chemical indicators (heap temperature, pH value, conductivity (EC), organic matter, total carbon (TC), total nitrogen (TN), total phosphorus (TP) and total porosity) The time of the system showed a certain change rule.It is required that physical and chemical indexes of the organic matrix for the composting heap temperature change, the fermentation cycle and the soilless culture of the equipment, the matured organic matrix with the 30% pig manure content is more suitable for crop cultivation , Maturity cycle suitable for factory production.
