Description

Technical Field

[0001] The present invention relates to the technical field of ecological breeding, and in particular to an integrated rice, shrimp and mandarin fish breeding system. Background Art

[0002] With the growing popularity of crayfish, more and more farmers are raising them, with many even raising them in rice paddies. However, lobster farming requires not only a suitable depth and clean water source, but also aquatic plants such as waterweed to provide shelter. Given the relatively simple environment between rice paddies, utilizing rice paddy ecosystems for lobster farming presents challenges. After careful research, we discovered several drawbacks to using rice paddies for crayfish farming. For example, the shallow water level in rice paddies creates a high water temperature during the summer months, making it unsuitable for crayfish growth. Furthermore, using drainage ditches surrounding rice paddies for crayfish farming presents drawbacks, such as a small drainage area, which results in a crowded breeding environment and poor growth. Therefore, we proposed an integrated rice, shrimp, and mandarin fish farming system to address these drawbacks. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: See Figure 1-Figure 3 , a rice, shrimp and mandarin fish integrated breeding system, comprising a rice planting area 2 surrounded by a rectangular inner ridge 1, an outer ridge 3 is provided outside the inner ridge 1, in this embodiment, the outer ridge 3 is U-shaped, the inner ridge 1 and the outer ridge 3 together form a breeding area 4, it is worth mentioning that the area of ​​the breeding area 4 is less than one tenth of the area of ​​the rice planting area 2; an inlet pipe 5 and a drainage pipe 6 are respectively passed through both sides of the outer ridge 3, the inlet pipe 5 is provided with a valve, and the drainage pipe 6 is connected to a drainage pump 7 at one end located in the breeding area 4, specifically, the outlet of the drainage pump 7 is connected to the inner end of the drainage pipe 6, the top surface of the inner ridge 1 is provided with an isolation net 8 along the circumference of the inner ridge 1, and an escape-proof belt 9 is provided on the inner peripheral wall of the outer ridge 3, which is used to prevent crayfish from crawling out of the rice planting area 2 and the breeding area 4. In addition, the inner bottom surface of the breeding area 4 is lower than the inner bottom surface of the rice planting area 2, and the inner bottom surface of the breeding area 4 is between 50 cm and 100 cm high from the top surface of the outer ridge 3. Since the top surfaces of the inner ridge 1 and the outer ridge 3 are flush, the breeding depth of crayfish is between 50 cm and 100 cm, which is just suitable for the growth of crayfish.

[0019] Inside the rice planting area 2 and near the edge of the inner ridge 1, a crawling channel 10 is inserted downwardly. The crawling channel 10 is made of a stainless steel square tube. The bottom end of the crawling channel 10 extends into the breeding area 4. Figure 2 As shown, the top of the crawling channel 10 is higher than the top surface of the inner ridge 1, and its function is to prevent water in the rice planting area 2 from flowing into the breeding area 4, and the top of the crawling channel 10 is tilted with an inclined plate 11, and the bottom end of the inclined plate 11 abuts against the inner bottom surface of the rice planting area 2; in addition, the bottom of the crawling channel 10 is fixedly connected with a spike 12, and the bottom end of the spike 12 is inserted into the breeding area 4 to fix the position of the crawling channel 10, and the angle between the crawling channel 10 and the horizontal plane does not exceed 45°.

[0020] like Figure 3 As shown, a deep ditch 13 is opened in the middle section of the inner bottom surface of the breeding area 4. The height of the inner bottom surface of the deep ditch 13 from the top surface of the outer ridge 3 is between 150 cm and 200 cm, and there are slopes 14 on both sides of the deep ditch 13, and the slope 14 does not exceed 50°. The deep ditch 13 can be used for breeding mandarin fish, and the water depth of 1.5 meters to 2 meters is just suitable for the growth and reproduction of mandarin fish.
