摘    要:在自动高温堆肥装置中,进行了4种调理剂对鸡粪锯末高温堆肥中的保氮效果实验,分析了堆肥化不同时期各处理中的堆温、pH值、水溶性氨氮、水溶性有机氮、全氮和有机碳的变化.结果表明,几种调理剂的加人对高温堆肥的堆温、pH值、水溶性氨氮、水溶性有机氮、TN和OC指标都有影响.都可降低堆肥过程氮素的损失;对OC的分解都有一定的促进作用.特别是同时添加草炭和过磷酸钙使堆肥高温期延长了5d,使堆制初期和高温期的pH值分别降低了0.89pH单位和0.44pH单位,使OC的降解率增加了60.7%,且使堆制过程中氮素的损失率下降了65.1%,有明显的保氮效果;而单加草炭或过磷酸钙效果次之;加沸石效果不明显.

关 键 词:鸡粪锯末  高温堆肥  调理剂  保氮效果

Abstract:In the automatic aerobic compost device, experiments were carried out to investigate the effect of four amendments on inhibition of nitrogen losses during the chicken manure and saw composting .The changes of chemical parameters, temperature, pH, water soluble ammonium and organic nitrogen, total nitrogen and organic carbon with time during the aerobic composting process were investigated. The results suggested that adding four amendments have certain effect on preserve nitrogen and chemical parameters. Treatments added different amendments all decreased the nitrogen losses and increased the decomposition of organic carbon for 40 days-composting. The effect extent of four amendments was adding peat and superphosphate together >adding peat >adding superphosphate >adding zeolite. Especially adding peat and superphosphate together prolonged the high temperature stage 5 days, decreased the pH 0.89pH unit in the initial stage and 0.44 pH unit in the high temperature stage during composting, and it decreased the nitrogen losses about 65.1% during the composting.
Keywords:chicken manure and saw  aerobic composting  amendment  effect of preserve nitrogen
