摘　　要：针对农业固体废物复混肥的生产工艺进行了工厂规模的试验研究，分别测定了物料含水率、有机物含量和无机物含量比例以及粒度对复混肥造粒效果的影响．通过工艺研究，确定出农村固体废物复混肥的最优生产工艺参数范围：原料含水率35％～40％，原料有机一无机比例80％～90％，原料粒度20目．田间种植试验的结果表明：在植株高度、重量以及有机质含量上，施用专用复混肥的作物高于施用化肥的作物，尤其是有机质含量，其差别尤为突出．说明农业固体废物复混肥具有增产增收的作用．Techniques of compound fertilizer production from solid waste compost were studied. Different ratio of water moisture, proportion between organic and inorganic and infection of different granularity to the effect of granulation is separately determined through experiments at the pilot scale in the field. The optimal parameters of the techniques are determined. The moisture content is 35 % -40 % ; the rate of organic matter is 80 % -90 % ; granularity is 20 mu. According the data of the organism＇s concentration, height and weight in crop, the crop was fertilized compound fertilizer is batter than chemical fertilizer. And the ability of increasing the production of the compound fertilizer was testified.
