The invention discloses a method for integral processing of breeding waste and crop straw by earthworms. The breeding waste and the crop straw are mixed uniformly according to a weight ratio of 2:1; the biogas slurry, the weight of which is 35 percent of that of the mixture of the breeding waste and crop straw, is added for anaerobic fermentation for a week; then the processed mixture after fermentation is moved to a livestock farm. The bottom of each culture pond is paved with crop straw with a height of 5 cm; then the processed mixture after fermentation is added, and the height of the mixture inside the pond is 0.4m; then 2kg earthworms are evenly distributed in the culture pond; finally a layer of the processed mixture after fermentation is paved thereon to a height of 0.45m in the pond. In a month, the earthworms are collected, and the substance inside the culture pool is put in the farmland as a fertilizer. By the invention, the breeding waste and crop straw can be processed effectively, the sustainable
