Current status and technical prospect of rice-duck mutualistic eco-farming in China

The eco-farming model of rice-duck mutualism is a comprehensive production technology combining the planting-breeding complex with eco-environment protection.Raising ducks in paddy fields has demonstrated positive effects on paddy ecology,such as intertilling and weeding,controlling insects and diseases,saving cost and improving soil fertility,stimulating rice growth,which significantly improves the system′s economic,social and ecological benefits.The status of the experiment and application of the technology of rice-duck mutualistic eco-farming system in China has been summarized,and some issues that need to be perfected and explored in future are put forward.pollution-free agriculture.
