畜禽废弃物的基质化处理研究

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.

Study on organic substrate production by composting swine manure

Wood shavings,tea and herb residue are mixed with different mass percent of swine manure,namely 0,20%,30% and 40%,as contrasting groups of the composting experiment for production of organic substrates.Composting temperature,water content,pH electrical conductivity(EC),total carbon(TC),total nitrogen(TN),total phosphorus(TP) and overall porosity were measured.Results showed that 30% swine manure are most appropriate so far as the effect on composting temperature,composting duration and physical chemistry indexes of soilless planting substrate are considered.
