The invention discloses a processing method of a goose dung fertilizer, relates to the field of livestock breeding, and in particular, relates to the processing method of the goose dung fertilizer. Provided is the processing method of the goose dung fertilizer and for turning the goose dung into treasure. The processing method comprises the following steps: mixing goose dung and corn straw powderevenly, placing the mixture in an anaerobic fermentation tank, regulating the pH to 7.5-8.5, fermenting for 50 days at the temperature of 30-50 DEG C, and discharging gas regularly during the fermentation. The mass ratio of the goose dung to the corn straw powder is 3:1 to 1:2. The gas is discharged for one time every 10 days. The processing method has the beneficial effects that the goose dung and corn straws are put into the anaerobic fermentation tank together and are fermented, the appropriate temperature, humidity and pH are adjusted, and the organic fertilizer for growing crops is obtained; the method is simple, the use of chemical fertilizers is reduced and the harm to the soil is reduced.
