Description

Technical Field

[0001] The utility model relates to the technical field of composite cultivation, in particular to a fish-vegetable symbiotic composite cultivation system suitable for light and simple facilities. Background Technique

[0002] Industrialized recirculating aquaculture has received extensive attention due to its high production efficiency, small environmental constraints, water and land conservation, etc. However, due to high stocking density, a large amount of aquaculture solid and liquid waste (about 80% of which is organic matter) will be generated during the production process. Direct discharge will cause environmental pollution and water eutrophication in the surrounding areas. Therefore, how to realize the resource utilization of waste is an urgent problem to be solved in industrialized recirculating aquaculture. The fish-vegetable symbiotic technology combines industrialized recirculating aquaculture with soilless vegetable cultivation, uses vegetables to absorb nitrate nitrogen, realizes biomass growth while being able to recycle the excess nitrogen (N) discharged from the aquaculture system, and maintains the controllability of aquaculture water quality. However, it fails to effectively solve the problem of the recycling of solid wastes such as fish feces and residual baits. At present, the treatment of aquaculture solid wastes mainly includes artificial wetland, composting, biofloc, fermentation and other technical methods, but there are different problems such as being greatly affected by the external environment, cumbersome operation and management, long treatment time, high labor and land costs, etc. Daylily is an important cash crop. Its flowers are steamed and dried to be processed into dried vegetables, namely golden needle vegetables or daylilies, which are sold far and wide at home and abroad and are very popular foods. Daylily is a fertilizer-loving crop. When cultivating, the land should be deeply plowed and a lot of organic fertilizer should be applied. When the fertilizer is sufficient, the plants grow vigorously and the yield is high. When the fertilizer is insufficient, the plants are short, the tillering is less, and the fertilizer requirement is the largest during the bolting period. Applying N, P, and K fertilizers in combination before bolting can make the flower stalks thick, the bolting neat, the flower buds plump, and the budding rate high.

[0003] In the existing fish-vegetable symbiotic composite cultivation system suitable for light and simple facilities, the problem of recycling solid wastes such as fish feces and residual baits has not been effectively solved. At present, the fertilization and water management of daylily planting land generally adopts the methods of centralized topdressing and manual fertilization, and mainly uses chemical fertilizers, resulting in waste of fertilizers and pollution of the soil environment, and at the same time affecting the improvement of daylily yield. For this reason, the utility model provides a fish-vegetable symbiotic composite cultivation system suitable for light and simple facilities. Content of the Utility Model

The surface of the driving block 524 is slidably connected to the inner surface of the sliding groove 514. The drainage component 53 includes a first water pump 531 installed on the left side of the aquaculture pond 1. The first water pump 531 is connected to the external circuit through a wire. The top of the first water pump 531 is fixedly connected to a connecting pipe 532 through a three-way valve. The top end of the connecting pipe 532 is fixedly connected to a hose 533. One end of the hose 533 is fixedly connected to one end of a drip irrigation pipe 515 through a shunt pipe 534.

The top end of the third water pump 71 is fixedly connected to the surface of the aquaculture pond 1 through a circulation water pipe 72. By starting the first water pump 531, the water in the aquaculture pond 1 is transported to the hydroponic system 4. After the water is purified by the crayfish and snails cultured in the hydroponic system 4, then by starting the third water pump 71, the purified water is circulated into the aquaculture pond 1, realizing water circulation and improving the utilization rate of water resources. By starting the second water pump 61, a small amount of tail water discharged from the sediment at the bottom of the aquaculture pond 1 enters the tail water pond 3. After microbial fermentation and mineralization, it is irrigated to the daylilies cultivated in the soil through the integrated water and fertilizer system, solving the problems of waste discharge and nitrate excess in the aquaculture pond 1, providing the nutrient components required for the growth of daylilies, realizing the ecological utilization of aquaculture water resources and waste, and the daylilies achieving water-saving and fertilizer-reducing cultivation, reducing production costs and improving efficiency.

[0028] In summary, aiming at the problem of resource utilization of solid-liquid waste in aquaculture and combining the water-saving and fertilizer-saving requirements in vegetable greenhouse production, based on the fish-vegetable symbiosis technology, a compound facility cultivation and breeding mode of vegetables and fish is proposed.

[0029] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] During operation, first, open the connecting water pipe 8 through the control valve, so that a small amount of tail water from the sediment at the bottom of the aquaculture pond 1 is discharged into the tail water pond 3.

At this time, start the driving motor 522 to drive the driving rod 523 and the driving block 524 to rotate. The driving block 524 slides on the inner surface of the sliding groove 514, so that the sliding plate 513 makes a reciprocating left and right sliding. The sliding of the sliding plate 513 drives the connecting plate 512 and the drip irrigation pipe 515 to slide reciprocally synchronously, so as to make the irrigation of the drip irrigation pipe 515 more uniform. In daily work, the diversion pipe 9 is connected to the aquaculture pond 1 through the three-way valve, and the connecting pipe 532 is closed. By starting the first water pump 531, the water in the aquaculture pond 1 is introduced into the hydroponic system 4 through the drainage pipe and the diversion pipe 9, and the water is purified and filtered by the crayfish and snails cultured in the hydroponic system 4. At this time, start the third water pump 71, and reintroduce the purified water into the aquaculture pond 1 through the branch pipe and the circulating water pipe 72 to form a water cycle and avoid waste of water resources. When the aquaculture pond 1 needs to be changed water or the daylilies in the soil cultivation system 2 need to be irrigated, the connecting pipe 532 can be opened through the three-way valve, so that the drainage pipe, the connecting pipe 532, the hose 533 and the drip irrigation pipe 515 are connected, and the diversion pipe 9 is closed. By starting the first water pump 531 and the driving motor 52, directly irrigate the daylilies planted inside the soil cultivation system 2, and the aquaculture pond 1 is replenished with fresh water from the outside.
