为了研究使用过的发酵床垫料能否作为有机肥施用于土壤,采用实地采样检测的方法,测定了使用过1、2及3年的发酵床垫料中有机质、全氮、全磷、全钾、速效氮、速效磷、速效钾浓度以及总养分含量和含水量,以及垫料中砷、汞、铅、镉、铬、铜含量。以未施用垫料的土壤作为背景值,检测施用3年垫料的土壤有机质、全氮、全磷、全钾、速溶氮、速溶磷、速溶钾和重金属砷、汞、铅、镉、铬、铜含量。结果表明:发酵床垫料水分、总养分不符合有机肥标准要求,有机质、pH值达到有机肥标准要求,有机质、全氮、全磷、全钾、速溶氮、速溶磷、速溶钾浓度均随垫料使用时间延长而增高,垫料中重金属浓度未超过国家标准,但随着垫料使用时间增长而增高。施用垫料的土壤有机物质含量明显高于未施用土壤,施用垫料土壤重金属含量略高于背景土壤重金属含量,富集现象不明显。此研究结论对发酵床废弃垫料应用提供技术支撑。 In order to study whether the used fermentation bed litter can be applied to soil as organic fertilizer, the organic matter, total nitrogen and total phosphorus in the fermented mattress materials that had been used for 1, 2 and 3 years were measured by field sampling and testing Potassium, available nitrogen, available phosphorus, available potassium concentration, total nutrient and water content, and arsenic, mercury, lead, cadmium, chromium and copper in litter. The soil organic matter, total nitrogen, total phosphorus, total potassium, instant nitrogen, instant phosphorus, instant potassium and heavy metal arsenic, mercury, lead, cadmium, chromium, Copper content. The results showed that the water and total nutrients of fermentation bed litter did not meet the standard requirements of organic manure. The organic matter and pH value reached the standard of organic manure. The concentrations of organic matter, total nitrogen, total phosphorus, total potassium, instant nitrogen, instant phosphorus and instant potassium The use of dunnage prolonged and increased, the concentration of heavy metals in dunnage did not exceed the national standard, but increased with the use of litter. Soil organic matter content of litter was obviously higher than that of non-applied soil. The content of heavy metal in litter soil was slightly higher than that of background soil, and the enrichment phenomenon was not obvious. The conclusions of this study provide technical support for the application of discarded litter in fermentation beds.
