The invention provides a rice-shrimp co-cropping bio-fertilizer and a rice-shrimp co-cropping method using the same, the method comprises the following steps: filling a culture ditch with water to submerge soil, then draining water and drying the field in the sun, putting the bio-fertilizer into the culture ditch, and uniformly burying the bio-fertilizer into the soil through manual or mechanical soil turning; irrigation is conducted in the breeding ditches again, submerged plants are planted, and then lobster populations are introduced for rice-lobster co-culture; before adult shrimps are harvested in each season and shrimp seeds are supplemented and put, the steps are repeated; the biological fertilizer is buried in the soil of the culture ditch, the submerged plants are planted on the surface of the soil, and the biological fertilizer can be gradually released into the water body by utilizing the characteristic of two layers of coatings of the fertilizer, so that nutrient substances can be released through
