A high-density duck raising system and duck raising method in double-cropping rice paddy field

Abstract

The invention discloses a high-density duck breeding system of a double cropping rice field and a duck breeding system. The duck breeding system comprises a rice field ditch system installed in the rice field. The rice field ditch system is internally provided with a first island for distributing the ducks entering and exiting the rice field; and a second island for insulating two groups of ducks visually. The duck breeding system is capable of remarkably improving the duck breeding density of unit rice field, wherein the duck breeding density is improved from 225-450 ducks / hectare to 1350-1500 ducks / hectare, remarkably increasing the number of the unit ducks and improving the unit production value. Through the change of the rice field landscape, the problem that the local rice seedlings are seriously damaged because of the congestion and trampling of the duck group in the process of entering the rice field can be solved.

Description

technical field [0001] The invention relates to a high-density duck raising system and a duck raising method in a double-cropping rice paddy field, belonging 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 number of ducks raised in traditional paddy field ecology is generally controlled at 15-30 per mu, such as a method for raising ducks in rice fields disclosed by Chinese Patent Publication No. CN105284732A, and a method for raising ducks and rice by Chinese Patent Publication No. CN102860286A. , 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 it...

Problems solved by technology

The number of ducks raised in traditional paddy field ecology is generally controlled at 15-30 per mu, such as a method for raising ducks in rice fields disclosed by Chinese Patent Publication No. CN105284732A, and a method for raising ducks and rice by Chinese Patent Publication No. CN102860286A. , 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
