本试验研究了热生物质灰对提高肉鸡粪便中矿物质含量和降低水分含量的贡献。为此，根据家禽粪便的干物质含量（74.77%），在不同的温度（100°C、150°C、200°C和250°C）下，以不同的速率（10%、20%、30%、40%和50%）添加生物质灰来制备混合物。结果表明：在250℃条件下，将生物质灰以50%的比例掺入禽粪中，可使禽粪含水率由25.23%降至9.82%；对于最终产物中N的最大值，生物质灰的理想温度为150℃。生物量灰分掺入50%时，养分含量最高。施用最高剂量的生物质灰显著提高了最终有机肥配方中Ca（19.34%）、K（4.03%）、Fe （1,545 mg/kg）、Mn （812 mg/kg）和Zn （479 mg/kg）等养分含量。综上所述，添加热生物质灰可以显著降低禽粪的水分含量，从而起到除臭和去除病原体的作用，并提高其植物营养成分含量。
In this study, the contribution of hot biomass ash to enrichment of the mineral content and to reducing the moisture content of broiler poultry manure was investigated. For this purpose, the mixtures have been prepared by adding biomass ash at varying rates (10%, 20%, 30%, 40% and 50%) and at different temperatures (100°C, 150°C, 200°C and 250°C) according to the dry matter content (74.77%) of the poultry manure. The results showed that incorporation of biomass ash into poultry manure at 50% at 250°C reduced the moisture content from 25.23% to 9.82%. Regarding the maximum N in the final product, the ideal temperature of biomass ash has been obtained at 150°C. The highest nutrient contents were obtained at 50% biomass ash incorporation. The highest dose of biomass ash application had significantly increased nutrients, such as Ca (19.34%), K (4.03%), Fe (1,545 mg/kg), Mn (812 mg/kg) and Zn (479 mg/kg) in the final organomineral fertiliser formulation. Overall, it was concluded that the addition of hot biomass ash can dramatically decrease the moisture content of poultry manure and therefore provide odour and pathogen removal and increase its plant nutrient content.
