Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, specifically to an ecological and efficient rice-fish co-culture facility. Background Technology

[0002] As is well known, aquaculture, due to its high stocking density, often leads to a decline in water quality caused by feed and fish excrement. At the same time, fish need a well-developed aquatic plant environment to survive. Simple aquaculture ponds generally cannot build a three-dimensional aquatic plant system. Rice requires essential nutrients during its growth. Usually, large amounts of chemical fertilizers are used to meet the high yield of rice, but the utilization rate is generally limited, resulting in the loss of some nutrients and agricultural non-point source pollution. If rice growth is combined with aquaculture, the excrement produced by fish can serve as nutrients for rice growth. At the same time, rice provides a good aquatic ecological environment and habitat for fish growth under flooded conditions, achieving a double harvest of fish and grain. Therefore, the symbiotic technology of rice production and aquaculture is particularly practical in areas with well-developed water systems.

[0003] Various rice-fish co-culture facilities exist in the existing technology. In order to enable the symbiotic co-culture of fish fry and rice, as well as the convenient flow of water and fertilization in the paddy field, a rice-fish co-culture facility that is easy to assemble and convenient to fertilize has been designed, thus creating a need for the use of such an ecological and efficient rice-fish co-culture facility. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an ecological and efficient rice-fish co-culture facility that solves the technical problems of symbiotic co-culture of fish fry and rice, convenient water flow within the paddy field, and fertilization.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an ecological and efficient rice-fish co-culture facility, comprising an isosceles trapezoidal trough, wherein three first circular through holes are respectively opened on the side walls at both ends of the isosceles trapezoidal trough, and a first tube is installed inside each of the three first circular through holes; a first rectangular through hole is opened on the upper wall of each pair of first tubes near the other side wall; a first rectangular groove is opened on the outer wall at both ends of the isosceles trapezoidal trough, and five first L-shaped hooks are respectively installed inside each pair of first rectangular grooves; two pairs of circular rings are respectively installed on the outer wall at the other two ends of the isosceles trapezoidal trough; and a rice placement mechanism is fitted on the upper wall of the first tube.

[0006] Preferably, the inner wall of the isosceles trapezoidal groove is provided with two pairs of second rectangular grooves, and an isosceles trapezoidal plate is movably inserted into each pair of second rectangular grooves.

[0007] Preferably, the rice placement mechanism includes a first box, the upper wall of the first box has a third rectangular groove, five second L-shaped hooks are respectively installed on the side walls at both ends of the first box, and three U-shaped grooves are provided on the lower wall of the first box.

[0008] Preferably, a triangular groove is installed on the side wall of the first box, and both the triangular groove and the first box are made of bamboo strips.

[0009] Preferably, each of the three U-shaped grooves has an arc-shaped plate installed inside, and each of the three arc-shaped plates has several second circular through holes on its side wall. Beneficial effects

[0010] This invention provides an ecological and efficient rice-fish polyculture facility. Rice seedlings are transplanted from late April to mid-May each year. Before transplanting, the paddy field is treated and fertilized with base fertilizer. The field is then irrigated for 10-15 days until the water quality stabilizes. After transplanting, the seedlings are nurtured. Ten to fifteen days after transplanting, the first batch of fish fry (specifically, rice paddy fish fry) is released, with a body length of 3-5 cm and a stocking density of 0.3-0.7 fry / m². Rice paddy fish feed is also provided to the fry, and daily management of both the rice and the fish is carried out. If it is necessary to change the water flow, this can be done by adjusting the water level... The trapezoidal plate 9 is fixed inside the isosceles trapezoidal trough 1, thereby enabling water to flow through the first pipe 2 and adjusting the water flow. Since the first box 5 is made of bamboo strips, the excrement produced by the fish fry can be used to fertilize the rice through the holes in the arc-shaped plate 8 and the first box 5. At this time, the fertilizer can be poured into the triangular trough 6, and the rice inside the first box 5 can be easily fertilized by diluting it with water and holes. Furthermore, through the connection of the first pipe, the fish fry can swim inside different isosceles trapezoidal troughs. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4 This invention provides a technical solution: an ecological and efficient rice-fish co-culture facility, comprising an isosceles trapezoidal trough 1, wherein three first circular through holes are respectively opened on the side walls at both ends of the isosceles trapezoidal trough 1, and a first tube 2 is installed inside each of the three first circular through holes. A first rectangular through hole is opened on the upper wall of each pair of first tubes 2 near the other side wall. A first rectangular groove is opened on the outer wall at both ends of the isosceles trapezoidal trough 1, and five first L-shaped hooks 4 are respectively installed inside each pair of first rectangular grooves. Two pairs of circular rings 3 are respectively installed on the outer wall at the other two ends of the isosceles trapezoidal trough 1. A rice placement mechanism is fitted on the upper wall of the first tube 2.

[0018] In terraced fields, suitable rice-fish co-culture paddy fields are selected. The planting area is chosen as a slightly acidic paddy field unit with a soil pH of 6 (triangular trough 6 to second L-shaped hook 7), free from pollution, and with good irrigation and drainage conditions. The paddy field is treated by draining the water before treatment and then disinfecting it. After disinfection, interval trenches are dug along the length of the paddy field. Isosceles trapezoidal troughs 1 are placed inside the trenches. The two end walls of multiple isosceles trapezoidal troughs 1 are then fixed to rings 3 using ropes. First tubes 2, placed side-by-side, are then joined together. A first box 5 is placed on top of the first tube 2. An arc-shaped plate 8 is placed above the through-hole of the first tube 2. The first box 5 and the isosceles trapezoidal troughs 1 are then secured by wrapping ropes around them. Soil and rice are placed inside the first box 5. Rice seedlings are transplanted from late April to mid-May each year. Before transplanting, the paddy field should be treated and fertilized with base fertilizer. The field should be irrigated for 10-15 days until the water quality stabilizes. After transplanting, the seedlings should be nurtured. Ten to fifteen days after transplanting, the first batch of fish fry (specifically, rice paddy fish fry) should be introduced. The fry should be 3-5 cm in length, and the stocking density should be 0.3-0.7 fry / m². Rice paddy fish feed should be provided at the same time, and daily management of both the rice and the fish should be carried out. If it is necessary to change the water flow at this time, this can be done by using an isosceles trapezoidal... The plate 9 is fixed inside the isosceles trapezoidal trough 1, thereby completing the flow of water through the first pipe 2 and thus adjusting the flow of water. Since the first box 5 is made of bamboo strips, the excrement produced by the fish fry can be used to fertilize the rice through the holes in the arc-shaped plate 8 and the first box 5. At this time, the fertilizer can be poured into the triangular trough 6, and the rice inside the first box 5 can be easily fertilized by diluting it with water and holes.

[0019] In this embodiment, the inner wall of the isosceles trapezoidal groove 1 is provided with two pairs of second rectangular grooves, and an isosceles trapezoidal plate 9 is movably inserted into each pair of second rectangular grooves.

[0020] In this embodiment, the rice placement mechanism includes a first box 5, a third rectangular groove is provided on the upper wall of the first box 5, five second L-shaped hooks 7 are respectively installed on the side walls at both ends of the first box 5, and three U-shaped grooves are provided on the lower wall of the first box 5.

[0021] Since the first box 5 is made of bamboo strips, the excrement produced by the fish fry can be used to fertilize the rice through the holes in the arc-shaped plate 8 and the first box 5. At this time, the fertilizer can be poured into the triangular trough 6, and the rice inside the first box 5 can be easily fertilized through the dilution of water and holes.

[0022] In this embodiment, a triangular groove 6 is installed on the side wall of the first box 5, and both the triangular groove 6 and the first box 5 are made of bamboo strips.

[0023] In this embodiment, each of the three U-shaped grooves is equipped with an arc-shaped plate 8, and each of the three arc-shaped plate 8 has a plurality of second circular through holes on its side wall.

[0024] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0025] Example: In a terraced field, a suitable rice-fish co-culture paddy field is selected. The planting area is a slightly acidic paddy field unit with a soil pH of 6 (triangular trough 6 to second L-shaped hook 7), free from pollution, and with good irrigation and drainage conditions. The paddy field is treated by draining the water before treatment and then disinfecting it. After disinfection, interval trenches are dug along the length of the paddy field. Isosceles trapezoidal troughs 1 are placed inside the trenches. The two end sidewalls of multiple isosceles trapezoidal troughs 1 are fixed to rings 3 with ropes. First tubes 2 are placed side-by-side and joined together. A first box 5 is placed on top of the first tube 2. An arc-shaped plate 8 is placed on top of the through-hole of the first tube 2. The first box 5 and the isosceles trapezoidal troughs 1 are secured by the first L-shaped hooks 4 and second L-shaped hooks 7 wrapped with ropes. Soil and rice are placed inside the first box 5 trough. Rice seedlings are transplanted from late April to mid-May each year. Before transplanting rice seedlings, the paddy field should be treated and fertilized with base fertilizer. The field should be irrigated for 10-15 days until the water quality stabilizes. After transplanting, the seedlings should be cared for. Ten to fifteen days after transplanting, the first batch of fish fry (specifically, rice paddy fish fry) should be introduced, with a body length of 3-5 cm and a stocking density of 0.3-0.7 fry / m². Rice paddy fish feed should be provided at the same time, and daily management of both the rice and the fish should be carried out. If it is necessary to change the water flow at this time, this can be done by adjusting the isosceles ladder. The shaped plate 9 is fixed inside the isosceles trapezoidal trough 1, thereby completing the flow of water through the first pipe 2 and thus completing the adjustment and circulation of water flow. Since the first box 5 is made of bamboo strips, the excrement produced by the fish fry can be used to fertilize the rice through the holes of the arc-shaped plate 8 and the first box 5. At this time, the fertilizer can be poured into the triangular trough 6, and the rice inside the first box 5 can be easily fertilized through the dilution of water and holes.
