Description

A rice field carp breeding system

technical field

The utility model belongs to the technical field of fish farming and relates to a paddy field carp breeding system.

Background technique

Raising carp in rice fields is one of the traditional aquaculture projects in rice field farming in my country. The traditional method of rice field farming can produce 40-70 kg of carp per mu without affecting the rice yield. The breeding water level is low, and the excavated fish ditch is relatively shallow, which affects the yield per mu of carp, resulting in poor breeding results.

Utility model content

The purpose of the utility model is to overcome the defects of the above-mentioned technology, and provide a paddy field carp breeding system with simple structure and stable rice production. The system can effectively use the marginal area of the field to increase the breeding water surface, and increase the yield per mu of paddy field carp.

Its specific technical plan is:

A paddy field carp culture system, comprising a paddy field, the paddy field area is 22.5 mu, 200 meters long, 75 meters wide, a ring ditch is dug between the paddy field and the ridge, the ring ditch is divided into 2 layers, and the ring ditch is divided into two layers. The width of the upper layer of the ditch is 2-2.5m, the slope is 45°-60°, the width of the lower layer is 0.6-1m, the slope is 75°-90°, the depth of the ring ditch is 1.0-1.4m, and the ring ditch is set next to the road. There are culverts, which also include water inlet pipes and drain pipes. The water inlet pipes and drain pipes are connected to the ring ditch. The ends of the water inlet pipes and the drain pipes are fixed with mesh covers made of iron wires. Regulate the paddy field water level, can drain the water in the paddy field completely, in the paddy field near the water inlet pipe, dug a holding pond, the length of the holding pond is 10-15m, and the width is 8-10m, and the holding pond The depth is 0.8-1m, and a fish collection pit is dug in the paddy field near the drainage pipe. The length of the fish collection pit is 6-8m, and the width is 4-6m. The depth of the fish collection pit is 1.1-1.5m. m.

Further preferably, the annular ditch has an inclination of 3‰ from the water inlet pipe to the drain pipe.

Compared with the prior art, the beneficial effects of the utility model are: (1) the structure is simple; (2) only the ring ditch is excavated, and the marginal effect of the paddy field is used to cultivate carp, and the breeding water surface accounts for 8-10% of the total area of the paddy field, The output of carp per mu is more than 120 kg, and the output of rice is also guaranteed, and it can ensure large-scale mechanical operations in rice fields, and its breeding effect is obviously better than traditional farming methods; (3) The end of the water inlet pipe and drain pipe is equipped with a net cover, which can effectively prevent carp Escape; (4) The ring ditch is divided into two layers, one is to increase the depth of water, which is beneficial to the growth of carp, and the other is that the bottom ring ditch has a slope of 3‰ from the water inlet pipe to the drain pipe, which is good for carp to gather in the fish collection pit, (5) There is a temporary pond dug in the paddy field near the water inlet, the length of the temporary pond is 10-15m, the width is 8-10m, and the depth of the pond is 0.8-1m, which meets the requirements of carp fry. breeding conditions. The utility model is suitable for large-scale and standardized production and use, and mainly solves the problems of low yield per mu of carp raised in paddy fields, difficult fishing, mechanical operations in paddy fields, and the like.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

With reference to Fig. 1-Fig. 2, the paddy field carp breeding system of the present utility model comprises paddy field 1, and described paddy field 1 area is 22.5 mus, is long 200 meters, and is wide 75 meters, has ring ditch dug between described paddy field 1 and ridge 2 9. The ring ditch 9 is divided into 2 layers. The upper layer of the ring ditch 9 has a width of 2-2.5m, a slope of 45°-60°, a lower layer of 0.6-1m in width, and a slope of 75°-90°. The ring ditch 9 depth is 1.0-1.4m, and described ring ditch 9 is provided with culvert 5 next to the road side, guarantees that carp is unobstructed in ring ditch 9, also includes water inlet pipe 6 and drain pipe 7, and described water inlet pipe 6 and drain pipe 7 are all communicated with the ring ditch 9, and the ends of the water inlet pipe 6 and the drain pipe 7 are fixed with an escape-proof net 8 made of barbed wire. Water, in the paddy field near the water inlet pipe 6, there is a temporary maintenance pool 3, which is used to temporarily raise carp seedlings. When temporarily raising the seedlings, it is not communicated with the ring ditch 9. The length of the temporary maintenance pool 3 is 10-15m , the width is 8-10m, the depth of the said support pond 3 is 0.8-1m, and the described paddy field near the drainage pipe 7 is dug with a fish collection pit 4, which is used for carp receiving goods, and the length of the described fish collection pit 4 is 6-8m, the width is 4-6m, and the depth of the fish collection pit 4 is 1.1-1.5m.

The above is only the best implementation mode of the present utility model. Anyone familiar with the technical field within the technical scope disclosed in the present utility model can obviously obtain the simple changes or equivalent replacements of the technical solutions all fall into the scope of this utility model. within the scope of protection of utility models.
