Many farmers will put ducks into the rice fields after harvesting the rice. What is the purpose of doing this?

Raising ducks in rice fields has also been promoted and tested in many foreign areas, and the conclusions are still very good. In this way, domestic ducks can not only eat weeds and insects in the rice fields, but the feces they pull out are equivalent to using manure to fertilize the rice fields. The coming and going of domestic ducks in rice fields can loosen the soil and stimulate the heading of rice plants. Therefore, raising ducks in rice fields is a good thing that kills two birds with one stone and can achieve double harvests of rice and ducks. However, there are various regulations for raising ducks in rice fields. It’s also time to put the ducks and geese into the rice fields. Generally, domestic ducks can be put into rice fields 10 days after planting. At this time, the seedlings have begun to change color, so duck activities in the rice fields will not affect their growth, and ducks will not eat the seedlings.

Problems of fertilizing and weeding. In fact, ducks raised in rice fields no longer expect to fertilize, weed, or spray pesticides. Some people are worried that the growth trend of rice will be affected. Since ducks actually eat weeds and insect pests, the excrement of domestic ducks is a natural organic fertilizer, which can increase the fertilizer efficiency of rice fields and thereby control costs! Duck farming in rice fields requires a reasonable distribution of the total number of domestic ducks. After planting rice fields, herbicides cannot be used and aquatic plants can grow naturally. Without the application of herbicides in this way, the drug residues in the rice will be greatly reduced, thus making progress towards pollution-free agriculture and animal husbandry. Ducks are omnivorous animals that not only peck at water plants, but also eat pests. It is recommended to stock 15 to 20 animals per square foot. The rice fields are rich, with many weeds and abundant herbivores, which can increase to 20 to 25 animals. It depends on the specific situation. The total number of ducks should not be too many. Otherwise, rice yields will be harmed.

Raising ducks in rice fields maximizes control over the application of chemical fertilizers. If poisonous or poisoned chemical fertilizers are used in rice fields, domestic ducks are strictly prohibited from getting out of their beds for at least 15 to 30 days. Therefore, harmful chemical fertilizers cannot be used. Ducks eat aquatic plants and insect pests, and rice diseases and insect pests are relatively reduced. In fact, after years of research, farmers who raise rice and ducks together have found that the chance of rice smut disease is low when ducks are raised in rice fields. Therefore, there is generally no need to inject drugs, thus saving manufacturing investment. Ducks are usually raised in rice fields, and rice diseases and insect pests are relatively reduced.

Raising ducks in rice fields is a new planting method in recent years, also known as the duck-rice interdependent planting model. Generally closely combined with organic chemistry or green planting. Neither chemical fertilizers nor organic fertilizers can be used. Use domestic ducks to weed, kill insects, and grow duck rice in duck manure fields to achieve a two-way effect of rice and ducks. It is recommended to build a goose shed every 10-15 acres to allow domestic ducks to rest at night. And prepare enough concentrated feed. Otherwise, domestic ducks will easily chew the leaves when they are hungry. After placing ducks in the rice fields, a water-proof layer of at least 10 cm should always be maintained on the field surface to facilitate the movement of domestic ducks. During the movement of domestic ducks, most of the Cyperaceae, broadleaf plants, and four families of wild grasses can be separated from the field surface, reducing the total number of native wild grasses in Guangzhou.

It can also gnaw away insect pests on the leaves, achieving the effects of weeding, killing insects, and fertilizing the fields.
