Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] The invention relates to a rice-duck symbiotic breeding method in which individual ducks of different sizes coexist, which comprises the construction of a rice field ditch system, a rice planting area, a duck pen area, and a feed isolation island.

[0031] The rice field ditch system in the construction of the paddy field ditch system is a "one-shaped" structure, and the "one-shaped" ditch is excavated along the inner side of the field ridge and other suitable areas in the field. A ring ditch is formed inside the edge of the field, and the center of the field remains in its original shape, forming a plane that is the field surface. The field surface is the part other than the ditch, that is, the field surface, which...

Abstract

The invention discloses a rice and duck symbiosis breeding method. The rice and duck symbiosis breeding method comprises the steps as follows: S1, constructing a rice field ditch system, and dividing the rice field into a rice planting area, a dusk fence area for ducks to stay at night and a feed isolation island; S2, planting early rice; S3, placing the first batch of ducklings 3-7 days after planting of the early rice; S4, placing the second batch of ducklings 40-55 days after planting of the early rice; S5, harvesting the first batch of ducks when the rice grows and develops to the filling stage; S6, harvesting the second batch of ducks before the rice is ripe and harvested. The rice-duck symbiotic period is significantly prolonged and the earrings are increased.

Description

technical field [0001] The invention relates to a rice-duck symbiotic breeding method, which 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 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. There...
