The "co-cultivation of rice and duck" makes a lot of money.

Corn can be intercropped with soybeans and celery to increase income. what can traditional rice fields raise to get rich? The rice planting area of Changchun Agricultural Expo Garden shows a compound and ecological income increasing model: raising ducks in rice fields and "co-cultivation of rice and ducks" can not only reduce the cost of weeding and insecticide in rice fields, but also harvest only "green and environmentally friendly" stocking ducks.

The reporter saw in the rice-growing area that a square rice field was covered with green rice, and a half-meter-wide zigzag canal was built around the rice field with cement and red brick. The breeze blew, the water rippled and the ears of rice surged.

"in fact, you can raise both fish and crabs in rice fields, but the simplest and most efficient one is the co-cultivation of rice and ducks." Technician Li Xiaowei said that "co-cultivation of rice and duck" means that by making use of the exuberant omnivorous nature of ducks, they can eat weeds and pests in rice fields, and the continuous activities of ducks can also stimulate the growth of rice and produce muddy water in the middle of farming. At the same time, duck droppings can also be used as fertilizer to "back-feed" rice seedlings.

In this paddy field, ducks and rice depend on each other and interact with each other to form an organic circular ecological chain, and the final result is high-quality pollution-free rice and "green environmental protection" stocking ducks. "Rice-duck co-cultivation" is a comprehensive agricultural production technology of planting and raising compound and ecological type. The use of this technology can not only effectively reduce the cost of planting rice and ducks, but also promote agricultural efficiency and increase farmers' income. " Li Xiaowei said that it is very simple and inexpensive for farmers to upgrade traditional rice fields to "rice-duck co-cultivation." all they have to do is to put a half-meter-high fine net around the rice fields. "also growing 15 mu of rice, using the model of'co-cultivation of rice and duck', farmers can earn at least 5000 yuan more per year on average."
