High-density duck raising system and method for raising ducks in paddy fields of early rice and ratooned rice

Abstract

The invention discloses a high intensity duck breeding system for the early season rice ratooning rice field and a duck breeding method. The duck breeding system comprises a rice field canal system arranged in the rice field, and a first island and a second island are arranged in the rice field canal system. The duck breeding intensity of a unit rice field is obviously increased by the system, duck breeding intensity increases from 225-450 piece / hectare to 1350-1500 piece / hectare, the unit quantity of duck breeding is obviously increased and the unit output value is increased; meanwhile the problem that local rice seedlings are seriously damaged by the congestion and trampling of the duck entering the rice field is solved by the change of the landscape of the rice field.

Description

technical field [0001] The invention relates to a high-density duck raising system and a method for raising ducks in paddy fields of early rice and ratooned rice, and belongs to the technical field of ecological breeding. Background technique [0002] Ecological duck raising technology in rice fields has been vigorously promoted and applied due to its functions of increasing production and efficiency and reducing methane emission in rice fields. The quantity of traditional paddy field ecological raising duck is generally controlled at 15-30 / mu, a kind of method utilizing paddy field breeding duck disclosed as Chinese Patent Publication No. CN105284732A, a kind of ecological raising duck rice breeding method that Chinese Patent Publication No. CN102860286A discloses , a method for raising ducks in paddy fields disclosed in Chinese Patent Publication No. CN1539274, these breeding densities can basically realize the control of weeds and pests, but cannot fully adapt to the need...

Problems solved by technology

The quantity of traditional paddy field ecological raising duck is generally controlled at 15-30 / mu, a kind of method utilizing paddy field breeding duck disclosed as Chinese Patent Publication No. CN105284732A, a kind of ecological raising duck rice breeding method that Chinese Patent Publication No. CN102860286A discloses , a method for raising ducks in paddy fields disclosed in Chinese Patent Publication No. CN1539274, these breeding densities can basically realize the control of weeds and pests, but cannot fully adapt to the needs of economic and social development, and its unit output value no longer possesses advantages. Therefore, further increase The unit output value contributes to the development and popularization of ecological duck raising technology in rice fields
