A low-cost batch wormcast or activated sludge drying method comprises the following steps of: mixing sawdust with wormcast to be treated, stacking the mixture into a 1m*2.5m (height) strip stack, standing for 2-3 days, turning over the mixture for 2-3 times per day, and naturally air-drying for 3-12 days. The wormcast obtained by the invention is a black, uniform and fine substance with natural soil flavor, the physical properties of the wormcast are determined by the properties of the raw materials and the digestion degree of earthworms, and the wormcast has good porosity, air permeability, drainage property and high water holding capacity. The wormcast has a large surface area, such that a lot of beneficial microorganisms can survive. The wormcast is rich in bacteria, actinomycetes and fungi, and the microorganisms can mineralize complex substances into effective substances easily absorbed by plants, and can synthesize a series of bioactive substances such as sugar, amino acids, vitamins and the like; and m
