[0002] Rice field duck farming is an ecological farming model that mainly grows rice and uses ducks for free-range farming. This model uses the interaction between rice and ducks, including environmental relationships and food chain relationships, to achieve sustainable agricultural production. Specifically, the practice of rice field duck farming includes using ducks to eat weeds and pests in the rice fields. At the same time, the activities of ducks can loosen the soil, massage, and stimulate the tillering of rice plants, producing the effect of muddy water and fertilizing the fields. This practice not only improves the organic degree of rice, but also reduces the use of chemical fertilizers and pesticides, achieving pure green production of rice. In addition, rice field duck farming is also called "rice-duck farming", which is an effective ecological agricultural technology that aims to minimize pollution in the rice-growing environment, while saving breeding costs and producing green, organic, high-quality rice and duck meat.

[0033] Example 1

[0034] There are 80 mu of rice fields for duck farming, with each rice field covering about 10 mu, and the breeding density of ducks is 80 per mu. The paddy field duck farming device of the above technical scheme is specifically implemented. The puddle is built at the center of gravity of the rice field plane, 50 cm deeper than the rice field plane, and the area of ​​the puddle is 25 square meters per mu of rice field. Rice is not planted in the puddle. There are ridges around the puddle, and there are multiple openings to the rice field on the ridge. The water inlet of the rice field is opened in the puddle, and the water source outside the rice field is connected to the puddle through a small canal. The canal ridge can be used for people to walk, and its height does not affect the work of the harvester. The duck house platform is about 1.5 meters higher than the normal water surface of the puddle, and the ramp connects the rice field and the duck house platform. The photovoltaic panel is placed on the roof of the duck house, and the arms around the duck house are covered with gauze in summer and insulation film in winter. A black light is installed under the duck house platform to attract insects. The duck house door includes an upper column curtain type and a lower automatic door. The automatic door opens at daybreak and closes at dark, making it easy for the ducks to enter and exit.

[0035] After the rice field transformation is completed, according to actual needs, rice can be planted first and ducks can be released, or ducks can be raised first and rice can be planted later. The rice should be planted with spacing for ducks to move around, and fertilization or pesticide application can be carried out according to conventional methods. When the rice is harvested earlier than the ducks, the rice field is filled with water after the rice is harvested to keep the ducks active. When the ducks are released, they are first placed in the duck house for three days, during which time they are given drinking water and food. After three days, the automatic control door system is activated. The duck manure falls from the platform into the rice field and flows into the entire rice field when water is poured into the rice field, which acts as a uniform fertilization.

[0036] After the rice and ducks were harvested, the average rice yield per mu increased by 50 jin and the number of commercial ducks increased by 80 (5 jin / ducks), achieving remarkable results.

[0037] Example 2

[0038] There are 10 mu of rice fields for duck farming, with each rice field covering about 5 mu and a duck breeding density of 60 ducks per mu. The paddy field duck farming device of the above technical scheme is specifically implemented. The puddle is built at the center of gravity of the rice field plane, 60 cm deeper than the rice field plane, and the area of ​​the puddle is 30 square meters per mu of rice field. Rice is not planted in the puddle. There are ridges around the puddle, and there are multiple openings to the rice field on the ridge. The water inlet of the rice field is opened in the puddle, and the water source outside the rice field is connected to the puddle through a small canal. The canal ridge can be used for people to walk, and its height does not affect the work of the harvester. The duck house platform is about 1.0 meter higher than the normal water surface of the puddle, and the ramp connects the rice field and the duck house platform. The photovoltaic panel is placed on the roof of the duck house, and the arms around the duck house are covered with gauze in summer and insulation film in winter. A black light is installed under the duck house platform to attract insects. The duck house door includes an upper column curtain type and a lower automatic door. The automatic door opens at daybreak and closes at dark, making it easy for the ducks to enter and exit.

[0039] After the rice field transformation is completed, ducks are raised first and then rice is planted according to actual needs. When planting rice, ducks are temporarily kept in the duck house. There should be spacing between rice plants for ducks to move around, and fertilization or pesticide application can be carried out according to conventional methods. When the ducks are released, they are first placed in the duck house for 3 days, during which time they are given drinking water and food. After 3 days, the automatic control door system is activated. Duck manure falls from the platform into the rice field and flows into the entire rice field when water is poured into the rice field, which has the effect of uniform fertilization.

[0040] After the rice and ducks were harvested, the average rice yield per mu increased by 55 jin and the number of commercial ducks increased by 60 (6 jin per duck), achieving significant results.
