Production method and equipment of pig manure fertilizer influencing yield of single-cropping late rice

The invention discloses a production method and equipment of a pig manure fertilizer influencing the yield of single-cropping late rice. The pig manure fertilizer is prepared from the following raw materials in parts by weight: 50 to 100 parts of biogas slurry, 0 to 0.196 part of nitrogen fertilizer, 0 to 0.275 part of phosphate fertilizer and 0 to 0.173 part of potash fertilizer. The biogas slurry formed by fermenting pig manure is used as a main raw material, a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer are added as auxiliary materials, and the biogas slurry and the phosphate fertilizer are used as base fertilizers to be applied at a time through sedimentation fermentation of the biogas slurry; the chemical potash fertilizer comprises 50% of base fertilizer and 50% of jointing fertilizer which are applied twice; 30% of the nitrogen fertilizer as the base fertilizer, 50% of the additional fertilizer in the seedling establishment period and 20% of the jointing fertilizer are applied f
