Can crabs and crayfish be raised in rice fields? What other small animals can you keep?

China has a wide area of rice fields, so it is advantageous to develop three-dimensional agriculture with the combination of planting and breeding. Fish and shrimp raised in rice fields can kill weeds and aquatic organisms, especially many harmful larvae. The activity of farmed animals loosens the topsoil and promotes the decomposition of organic matter. At the same time, through metabolism, faeces discharged by animals play a role in increasing fertilizer, so that the use of chemical fertilizers and pesticides is relatively small, ensuring stable and high quality production of rice, achieving high efficiency, ecology and safety, and the price is several times that of ordinary rice. The original ecological culture way makes the farmed products grow in the imitating wild environment, and the high quality is more popular in the market, which can increase the income by thousands of yuan per mu.

"Rice field farming" can raise not only fish, but also shrimp, crabs, soft-shelled turtles, mud mackerel, rice eel and soft-shelled turtles. Let's have a look with the editor.

1. Fish culture in rice fields

Rice field fish culture is a traditional farmland production mode in the mountainous and hilly areas of southern China, which is called "rice bottom fish". Fish farmed in rice fields are mainly grass carp and carp, and crucian carp, silver carp, bighead carp, mud carp, crucian carp, catfish, tilapia and so on. One mu of rice fields raises one or two thousand fish, which can be salvaged and sold in seven or eight months, with an average yield of four to five hundred jin of fish per mu.

2. Raise crabs

River crab not only plays the role of ploughing, weeding, increasing fertilizer and oxygen, but also reduces diseases and insect pests by moving and foraging in the paddy field.

3. Raise crayfish

Lobsters can eat pests and weeds in paddy fields, and the process of swimming and foraging helps to loosen the soil, live water, aerate and increase the dissolved oxygen in paddy water. It is understood that each mu of rice fields can cultivate more than 3000 lobsters, producing about 300jin of lobsters.

4. Raise Loach

Misgurnus anguillicaudatus is an omnivorous fish, which feeds on insects, small crustaceans, tender leaves of aquatic plants, diatoms, cyanobacteria, green algae, xanthophyta and zooplankton. It also likes to eat rice borer eggs and brown planthoppers, which can help control rice field diseases and insect pests. Misgurnus anguillicaudatus swims up and down in the shallow water of the paddy field to loosen the soil to promote the growth of rice roots, while the excrement of Loach has become a high-quality organic fertilizer for rice growth. It is understood that Loach can produce about 400 jin per mu.

5. Raise frogs

Farmed frogs have become a delicacy on the dinner table, and there are good prospects for raising frogs in rice fields. Frogs are the natural enemies of pests in rice fields. Making use of the mutually beneficial symbiotic relationship between rice and frogs, rice cultivation and frog culture are organically combined to achieve the goal of increasing production and income and protecting the natural ecological environment.

When breeding in rice fields, pesticides should be used as little as possible. If necessary, pesticides with high efficiency and low toxicity should be selected and sprayed on cloudy days. At the same time, keep the water quality fresh and prevent excessive feeding and fertilization from affecting the water quality. In addition, we need to master aquaculture technology, do a good job in natural enemy defense, and increase output.

The development of comprehensive cultivation and cultivation of rice and fishing not only ensures the "rice bag" but also enriches the "vegetable basket"; it not only encourages the "money bag" of the common people, but also ensures the "safety on the tip of the tongue." it uses both water and water, gains two crops in one field, stabilizes the income of grain and increases the income of grain and fishing.
