Abstract
Description
Technical Field
[0001] The utility model relates to a lighting greenhouse breeding system for commercial turtle breeding. Background Art
[0002] In recent years, the price of soft-shelled turtles has remained low. Currently, most farmers rely on greenhouse farming, using methods described in Chinese patent CN101069490A. This has resulted in losses for farmers. Current measures are aimed at extending the growth cycle and improving the quality of soft-shelled turtles. This is achieved by switching to open-air pond farming, which is subject to extreme weather conditions, resulting in a short effective growth period, slow growth, a high feed conversion ratio, small size of the turtles, and high costs. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a lighting greenhouse breeding system for commercial turtle breeding, which has sufficient light and adopts micro-flow water breeding to maintain water quality and improve the growth rate of turtles.
[0004] In order to solve the above technical problems, the utility model provides a lighting greenhouse breeding system for commercial turtle breeding;
[0005] It consists of a rectangular concrete pool with an open upper side;
[0006] An arched roof is provided on the upper side of the pool, extending across the width of the pool. The vertical projection of the roof is sufficient to cover the entire pool. The roof comprises a plurality of arched frames evenly spaced along the length of the pool and extending across both sides of the width of the pool. A polyethylene net is laid on the upper side of the frame, a rainproof sheet is laid on the upper side of the polyethylene net, and a rope net is provided on the upper side of the rainproof sheet. The rope net presses the rainproof sheet onto the polyethylene net and the frame.
[0007] A vertical concrete partition is provided in the middle of the length of the pool. The length direction of the partition is consistent with the width direction of the pool, and the height of the partition is consistent with the height of the pool. The partition divides the pool into two breeding pools. The bottom of each breeding pool is a slope along the length of the pool, with a higher height on the side close to the partition and a lower height on the side away from the partition.
[0008] A water inlet pipe is provided near the upper part of the partition and is arranged horizontally along the length direction of the partition. A number of water outlet pipes are provided on both sides of the partition corresponding to the water inlet pipe and are arranged horizontally and with their axes perpendicular to the water inlet pipe. The water outlet pipes on each side of the partition are arranged at equal intervals along the length direction of the water inlet pipe. One end of each water outlet pipe is connected to the water inlet pipe, and the other end of each water outlet pipe passes through the partition and is installed with an inlet valve. A threaded joint is provided at the end of the water inlet valve away from the water inlet pipe in the water channel direction, and a horizontally arranged straight duckbill sprinkler is screwed onto each threaded joint.
[0009] Each aquaculture pond has a pre-buried pipe at the bottom of the pond, near the side with the lower height of the pond bottom. The pre-buried pipe is arranged below the pond bottom. One end of the pre-buried pipe vertically penetrates the bottom of the corresponding aquaculture pond and is provided with a circular plug joint. The upper side of the plug joint is flush with the bottom of the corresponding aquaculture pond. An annular slot coaxially arranged with the plug joint is provided at the corresponding plug joint at the bottom of the aquaculture pond. The upper side of the annular slot is open and its diameter is larger than the diameter of the plug joint. The upper side of the annular slot is flush with the bottom of the aquaculture pond. The other end of the pre-buried pipe is led out of the aquaculture system. The pre-buried pipe plug corresponding to the position in each aquaculture pond is connected to the aquaculture pond. A vertical drain pipe is provided at the head which is coaxially arranged with the plug joint. The drain pipe comprises an inner tube and an outer tube which are connected inside and outside. The height of the inner tube is lower than that of the outer tube. The lower part of the outer tube is plugged in with the annular slot. A number of through holes which radially penetrate the outer tube are circumferentially provided on the lower part of the outer tube. The through holes are arranged in a matrix on the outer tube. The height of the uppermost side of the perforated area of the outer tube is 400mm. The inner tube comprises an upper tube and a lower tube which are arranged up and down. The upper tube and the lower tube are coaxially plugged in with a plug-in direct joint provided therebetween. The lower tube is plugged in with the plug joint. The height of the lower tube is 600mm.
[0010] Preferably, the skeleton is a galvanized square tube.
[0011] For the purpose of simple explanation, the lighting greenhouse breeding system for commercial turtle breeding described in the present invention is referred to as this system for short.
[0012] The usage and advantages of this system are as follows: Before releasing the turtles, water is stored in the pond. At this time, there is no need to install a straight-line duckbill nozzle. Just open the water inlet valve to store water. After releasing the turtles, install a straight-line duckbill nozzle on the water inlet valve. The straight-line water flow has little impact on the water surface in the breeding pond, which can reduce water turbidity. This can also increase the contact area between water and air, and increase the dissolved oxygen content in the water. The drainage method is that the bottom water in the breeding pond passes through the through-hole of the outer pipe and enters between the outer pipe and the inner pipe, then overflows upward and enters the inner pipe from the upper end of the inner pipe. It flows from top to bottom in the inner pipe and is finally discharged from the embedded pipe. The advantage of using this overflow structure for drainage is that during the breeding process, a micro-flow is always maintained in the breeding pond, and the bottom water can be discharged. Compared with the upper water, the bottom water has low dissolved oxygen, more suspended matter, and higher ammonia nitrogen and nitrite. Through this structure, the bottom water is discharged, which better improves the water quality. Since the water level in the breeding pond is actually determined by the height of the inner pipe, the inner pipe is divided into an upper pipe and a lower pipe in order to adjust the water level in the breeding pond. By flexibly adjusting the length of the upper pipe, the appropriate water level in the breeding pond can be ensured. The upper and lower pipes are connected by a direct joint, which makes it easy to replace the upper pipe. The lower pipe is connected to the embedded pipe joint, so if you want to drain the pool water, just unplug the inner pipe from the joint.
[0013] This system has sufficient light and adopts micro-flow aquaculture, which can maintain water quality, diversify disease prevention and control, increase the growth rate of turtles, and improve the survival rate of aquaculture. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-Figure 5 (The attached figure is only a schematic representation of the structure and does not represent the specific size).
[0020] A light-collecting greenhouse culture system for commercial turtle culture;
[0021] It includes a rectangular concrete pool with an open top, 100 meters long, 13 meters wide and 1.8 meters deep. The average water depth during aquaculture is 1.2 meters.
[0022] An arched roof 2 spans the width of pool 1 above pool 1. Its vertical projection is sufficient to cover the entire pool 1. Roof 2 comprises several arched frames 21 evenly spaced along the length of pool 1 and spanning both sides of its width. Frames 21 are constructed of galvanized square tubes, 1.8 mm thick, 60 mm long and 20 mm wide, with an arch height of 2.5 meters and a spacing of 1 meter between tubes. Polyethylene mesh 22 is laid above frame 21, and a 10-wire thick tarpaulin 23 is placed above it. A rope net 24 is installed above tarpaulin 23, pressing the tarpaulin 23 against the mesh 22 and frame 21.
[0023] A vertical concrete partition 11 is provided in the middle of the length direction of the pool 1. The length direction of the partition 11 is consistent with the width direction of the pool 1. The height of the partition 11 is consistent with the height of the pool 1. The partition 11 divides the pool 1 into two breeding pools 3. The bottom 12 of each breeding pool 3 has a slope value of 20 along the length direction of the pool 1, with the side close to the partition 11 being higher and the side away from the partition 11 being lower.
[0024] A PVC water inlet pipe 4 is provided near the upper part of the partition 11 and is arranged horizontally along the length direction of the partition 11. The inner diameter of the pipe is 50 mm. The water inlet pipe 4 is provided with a number of horizontally arranged outlet pipes 41 whose axial direction is perpendicular to the water inlet pipe 4 at both sides of the partition 11. The outlet pipes 41 on each side of the partition 11 are arranged equidistantly along the length direction of the water inlet pipe 4. One end of each outlet pipe 41 in the length direction is connected to the water inlet pipe 4. The other end of each outlet pipe 41 in the length direction passes through the partition 11 and is equipped with an inlet valve 42. The inlet valve 42 has a diameter of 20 mm. A threaded joint 43 is provided at one end of the inlet valve 42 away from the inlet pipe 4 in the waterway direction. A horizontally arranged straight-line duckbill nozzle 44 is screwed on each threaded joint 43. During breeding, the nozzle 44 is 50 cm away from the water surface.
[0025] Each culture pond 3 has a pre-buried pipe 5 at the bottom 12 thereof, which is close to the side with the lower height of the bottom 12 thereof. The pre-buried pipe 5 is arranged below the bottom 12 of the culture pond 3, and the inner diameter of the pre-buried pipe 5 is 110 mm. One end of the pre-buried pipe 5 vertically penetrates the bottom 12 of the corresponding culture pond 3 and is provided with a circular plug joint 51. The upper side of the plug joint 51 is flush with the bottom 12 of the corresponding culture pond 3, and the corresponding plug joint 51 at the bottom of the culture pond 3 is provided with an annular slot 622 coaxially arranged with the plug joint 51. The upper side of the annular slot 622 is open and its diameter is larger than the diameter of the plug joint 51. The upper side of the annular slot 622 is flush with the bottom of the culture pond 3 (due to the low slope and small diameter, the bottom 12 of the culture pond 3 is approximately regarded as a plane, and the plug joint 51 and the annular slot 622 are both regarded as vertically arranged). The other end of the pre-buried pipe 5 is led out of the culture system. The vertical drain pipe 6 is coaxially arranged with the head 51. The drain pipe 6 includes an inner pipe 61 and an outer pipe 62 that are connected to each other. The inner diameter of the inner pipe 61 is 110 mm, the inner diameter of the outer pipe 62 is 315 mm, the height of the inner pipe 61 is lower than the height of the outer pipe 62, the lower part of the outer pipe 62 is plugged into the annular slot 622, and the lower part of the outer pipe 62 is connected to the bottom 12 of the breeding pond 3. The lower part of the outer pipe 62 is circumferentially provided with a plurality of through holes 621 that penetrate the outer pipe 62 in a radial direction. The through holes 621 are provided in a circular manner. 21 are arranged in a matrix on the outer tube 62, the through hole 621 has a diameter of 10 mm and a hole pitch of 10 mm, the uppermost height of the perforated area of the outer tube 62 is 400 mm, and the inner tube 61 includes an upper tube 611 and a lower tube 612 arranged up and down, the upper tube 611 and the lower tube 612 are coaxially connected through a plug-in direct connector 613 provided therebetween, the lower tube 612 is plugged in with the plug connector 51, and the height of the lower tube 612 is 600 mm.
[0026] The advantages of this system include: Before releasing the turtles, water is stored in the pond. At this point, there's no need to install a straight-line duckbill nozzle 44; simply open the water inlet valve 42 to store water. After releasing the turtles, install the straight-line duckbill nozzle 44 on the water inlet valve 42. This straight-line flow of water exerts minimal impact on the water surface within the aquaculture pond 3, reducing water turbidity. This also increases the contact area between water and air, increasing dissolved oxygen levels. The system also features a drainage system where the bottom water within the aquaculture pond 3 flows through the through-holes 621 of the outer tube 62 and into the space between the outer tube 62 and the inner tube 61. The water then overflows upward and enters the inner tube 61 from its upper end, exiting the system from the main pre-buried pipe 5. This overflow structure maintains a constant flow of water within the aquaculture pond 3 during the aquaculture process, allowing the drainage of bottom water, which is low in dissolved oxygen, high in suspended solids, and high in ammonia, nitrogen, and nitrite. This structure allows for the drainage of bottom water, improving water quality. Since the water level in the breeding pond 3 is actually determined by the height of the inner tube 61, the inner tube 61 is divided into an upper tube 611 and a lower tube 612 in order to adjust the water level in the breeding pond 3. By flexibly adjusting the length of the upper tube 611, the appropriate water level in the breeding pond 3 can be ensured. The upper tube 611 and the lower tube 612 are connected by a direct connector 613, which makes it easy to replace the upper tube 611. The lower tube 612 is plugged into the pre-buried pipe 5 connector 51. In this way, if the pool water needs to be drained, the inner tube 61 can be unplugged from the connector 51.
[0027] This system has sufficient light and adopts micro-flow aquaculture, which can maintain water quality, diversify disease prevention and control, increase the growth rate of turtles, and improve the survival rate of aquaculture.
[0028] Regarding the specific variety selection, the patented breeding variety is the new variety of Chinese soft-shelled turtle "Changhuai No. 1". This variety grows fast and its weight increases by 16% at 5 months of age compared with conventional varieties of the same type. It has high market recognition for its body shape and color, good quality, and stable economic benefits.
[0029] Traditional aquaculture uses soft pellets by mixing powdered turtle feed with water. These pellets are then prepared and used immediately. However, this approach is labor-intensive and prone to spoilage in hot weather. Furthermore, the wet feed sinks in the water due to its poor stability, dispersing upon contact with water and causing waste and water pollution. Furthermore, the sinking of the feed makes it difficult to determine whether the turtles have consumed the feed. The feed coefficient is therefore above 2. Flow-through aquaculture uses floating, extruded pellets. These pellets are purchased from a professional feed manufacturer and stored in sealed containers. When feeding, the package is opened and the feed is directly placed in the feeding basket according to the feeding amount. Extruded feed reduces manual preparation, allowing the feed to float in the water's feeding basket, making it easier to monitor consumption. Furthermore, since the feed is processed by a professional feed manufacturer, it is highly stable and can float in water for six hours without dissipating. The feed coefficient is 1.8. The food frame is rectangular, 4 meters long and 2.5 meters wide. The long side and the wide side are connected with the same type of PVC elbows. When installing, apply sealant inside the elbow to ensure that water cannot enter the pipe. When the glue is almost dry, insert the long and wide side pipes into place. The material is a 50 mm diameter PVC pipe.
[0030] Whether disinfection is scientifically sound affects survival rates. Two conditions are necessary for turtles to become sick: an opportunity for infection and the presence of sufficient pathogens. When turtles are injured by stacking, squeezing, or transport, creating opportunities for pathogens to invade, or when environmental changes such as air temperature, water temperature, and light levels cause stress reactions, weakening their immunity and leading to organic diseases. Traditional disinfection methods involve applying a medicated bath to the turtles before they are released into the pond for 5-10 minutes, followed by continuous application of disinfectant for 3-5 days. This method has the disadvantages of secondary scratching and squeezing of the turtles, the high concentration of irritants in the bath, and the high stress levels. Furthermore, continuous disinfection with a single drug after release narrows the sterilization range and results in poor disinfection effectiveness. The disinfection method adopted by this patent is: no concentrated medicinal bath is performed on the turtles before they are put into the pond to reduce the chance of being squeezed and scratched; anti-stress products are sprinkled into the micro-flow pool when the turtles are about to be put into the pond; 5 hours after the turtles are put into the pond, a low-irritation disinfectant is sprinkled once; after 10 days, a high-efficiency disinfectant is sprinkled once; after another 17 days, an oxidant is sprinkled once. The survival rate of aquaculture using this disinfection method reaches 98%, which is 6% higher than the survival rate of conventional disinfection, and the defective rate of commercial turtles is reduced by 10%.
[0031] This patent has achieved the following results: the Chinese soft-shelled turtle "Changhuai No. 1" was cultivated. A total of 7.5 catties of seed turtles were stocked per square meter, with a size of 1.5 catties. After five months of cultivation, the turtles were 2.5 catties in size, with a net weight gain of 1 catties. The yield per square meter was 11.25 catties. The turtles were greenish-yellow in color and were very popular in the Yangtze River Delta market. The feed coefficient was 1.8. Compared with conventional aquaculture, the size of the turtles increased by 15%, the feed coefficient decreased by 12%, the cultivation cost decreased by 23%, and the profit per square meter increased by 45 yuan.
