Abstract: Rice-duck farming ecological technology is to leave the ducklings in the paddies all day long, to stimulate the growth of rice, promote the material circulation and improve paddy environment by using ducks’ continuous activities. As a result, a new farming mode was built, which combined planting and feeding together, reduced cost and increased efficiency and promoted the matter cycle. The authors reviewed the impacts of integrated rice-duck farming technology on matter accumulation of rice, strong stem effect, root activity, injurious insects and weeds controlling, biological diversity, soil physical-chemical properties, methane emission and controlling nitrogen loss, and elaborated the successful planting and feeding mode practices of the integrated rice-duck farming ecological implementation such as the release of duckweed, rice-duck farming system with two-batch-duck raising, the release of ducks aged zero day, methane-rice-duck cycling, insect-proof screen mulching and so on. The authors also pointed out the problems that to be solved in integrated rice-duck farming ecological agricultural development, and the study could provide references for the technological theories and practice development of integrated duck-rice farming system.
