Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a rice, shrimp, and fish symbiotic breeding method. Background Art

[0002] Traditional rice-fish farming methods require excavating rice paddies (fishing ditches). These ditches are then cut off from the rice fields during tillering, drying, fertilizing, spraying, and tillage to prevent adverse effects on the fish. This method suffers from the impact of excavating rice paddies on food production, and the small size of the fishing ditches prevents large-scale farming.

[0003] Barrel aquaculture is a facility-based fish farming method characterized by high density, high output, high profitability, and short production cycles. However, high levels of feeding also lead to significant pollution. Aquaculture effluent treatment primarily involves chemical methods and the "three ponds, two dams" approach. Chemical methods require large amounts of chemical reagents and are costly to operate. The "three ponds, two dams" approach requires significant land use, wastes nutrients in the water, and has low overall economic returns.

[0004] With the rapid expansion of intensive farming methods such as barrel aquaculture, the treatment of aquaculture tailwater is becoming increasingly urgent. Therefore, integrating rice farming with aquaculture tailwater treatment will help promote high-quality development of the fishery industry. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a method for symbiotic cultivation of rice, shrimp and fish. The tail water generated by the fish culture in the barrel is passed through the rice ecosystem of the A field and the B field to absorb ammonia nitrogen, nutrients, etc., and the purified water is circulated into the barrel, thereby achieving efficient cultivation and breeding of rice, crayfish and freshwater fish, and realizing efficient resource utilization.

[0006] The present invention provides a technical solution to solve the above problems: a rice, shrimp and fish symbiotic cultivation method, comprising three relatively independent systems: a barrel fish cultivation system, a "shrimp-rice" integrated cultivation and breeding system in field A, and a "shrimp-rice-rice" integrated cultivation and breeding system in field B, which are connected together by a circulation component;

[0007] Barrels can achieve high-density farming;

[0008] The tailwater from the barrel fish farming system is discharged into the integrated shrimp-rice farming system in plot A and the integrated shrimp-rice-rice farming system in plot B.

[0009] The "shrimp-rice" integrated farming system in plot A and the "shrimp-rice-rice" integrated farming system in plot B purify the aquaculture tail water;

The periphery of the barrel is a metal circle frame and the inner layer is a barrel-shaped structure composed of canvas with an upper opening. The bait feeding machine automatically feeds the barrel with bait at a fixed time. The bird-proof net covers the top of the barrel. The aerator is connected to the barrel through an air duct.

[0014] Preferably, the second delivery pipe is tangentially connected to the barrel.

[0015] Preferably, a water quality sensor 1 is installed in the circle barrel, and the water quality sensor 1 is electrically connected to the sewage pump; a water quality sensor 2 is installed at the water outlet of the A field "shrimp-rice" integrated breeding system and the B field "shrimp-rice-rice" integrated breeding system, and the water quality sensor 2 is electrically connected to the circulating water pump.

[0016] Preferably, the ridges of the "shrimp-rice" integrated farming system in field A are made by compacting the soil layer by layer to increase height, width and reinforcement, with a height greater than 100 cm and a width greater than 80 cm. 50 cm high glass tiles or porcelain pieces are buried in the ridges as escape prevention facilities.

This integrated rice farming method requires no excavation and does not damage farmland. This fully utilizes rice field resources without impacting rice production or grain yields.

[0034] 2. This rice-shrimp-fish symbiotic farming method uses plots B and A with different growing periods (early rice, mid-season rice, late rice) and different cropping patterns (single-season rice and double-season rice). This ensures sufficient water for barrel farming during special periods, such as rice tillering and drying, fertilizing, and spraying pesticides.

[0035] 3. This rice-shrimp-fish symbiotic farming method divides the rice field into multiple "S"-shaped water flow channels, improving the rice field's absorption and utilization of ammonia nitrogen and phosphate in the aquaculture tail water;

[0036] 4. This rice-shrimp-fish symbiotic farming method cultivates a batch of crayfish before transplanting rice, thereby improving economic benefits by bringing crayfish to the market early and cultivating large-sized crayfish;

[0037] 5. This rice, shrimp and fish symbiotic breeding method separates the barrel farming system from the rice field breeding system, making up for the shortcomings of traditional rice field fish farming with low fish yield and low efficiency, and greatly improving fish farming output and ecological and economic benefits.
