Abstract: Rice-duck farming originated in China and matured in Japan.It has such significant technological advantages as protecting eco-environment and causing great economic benefits.And it is a new model of eco-agriculture which has been popularized in rice main production regions of China.The article explores some problems about rice-duck farming technology including lacking in-depth research,no matched techniques,misunderstanding of farmers,incompatible generalization mechanism,and slow generalization progress.The paper also proposes that technical research should be strengthened,and the cultivation model should be innovated.With leading enterprises as leader of agricultural industrialization,the mechanism of ＂company ＋ base ＋ farmers＂ should be implemented,and the generalization progress should be accelerated.
