title: [Using compost of agricultural solid waste to produce organic-inorganic compound fertilizer].
abstract: 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.
