The workshop 5 is used for placing farm tools and performing agricultural production operations, the storage room 6 is used for storing agricultural products and agricultural supplies, and the toilet 7 is convenient for use by staff.

[0038] A pig breeding area 8 is provided at the corner of the ditch 3. The pig breeding area 8 is located at a diagonal position away from the entrance of the rice field 1 to reduce interference with the rice field 1. A pig landing road 9 is provided between the pig breeding area 8 and the internal road 4 to facilitate the entry and exit of the pigs and the transportation of feed. A septic tank 10 is provided in the pig breeding area 8 to convert pig manure into organic fertilizer for fertilizing the vegetable greenhouse 2 and the rice field 1. A water inlet and outlet system 11 is also provided at the corner of the ditch 3 to adjust the water level of the ditch 3 and irrigate the rice field 1.

[0039] A crab nest 12 for breeding crabs is arranged at the edge of the rice field 1, which can make full use of the ecological environment of the rice field 1 and improve the comprehensive benefits of agricultural production.

[0040] In the specific implementation, the vegetable greenhouse 2 can adopt a concrete frame structure, which is strong and durable, and has good heat preservation and moisture retention performance. The vegetable greenhouse 2 is provided with an inner road 13, which divides the vegetable greenhouse 2. The walls between the functional areas are provided with water habitats (hollow bricks). According to the needs of crop growth, the water level can be freely controlled, so that crops and aquatic products can achieve the best integration state, allowing the ecology to enter a virtuous cycle, saving labor and fertilizer, and achieving multi-layer space utilization.

[0041] The top of the vegetable greenhouse 2 is designed with a slope surface, which is conducive to drainage and ventilation. A sightseeing passage 15 is arranged on the top of the vegetable greenhouse 2, and a solar photovoltaic panel 16 is arranged on the top of the sightseeing passage 15 to achieve green utilization of energy. A non-powered pumping device 17 is arranged at the bottom of the sightseeing passage 15. The non-powered pumping device does not require electrical drive and operates on the siphon principle to circulate the water:

[0042] 1. It can cool down the greenhouse in summer and melt snow in winter, forming a beautiful landscape;

[0043] 2. Meet the oxygen demand of aquatic products;

[0044] 3. It can meet the irrigation needs of vegetables.

[0045] A pig jumping platform 18 is provided on one side of the pig breeding area 8 near the ditch 3, which is convenient for the pigs to enter the ditch 3 to swim and forage, which is beneficial to the healthy growth of the pigs. A feed inlet 19 is provided on one side of the pig breeding area 8 near the internal road 4, which is convenient for the transportation and feeding of feed.

[0046] The drainage system 11 includes a wire mesh gate 20 and a main drainage pipe 21. The wire mesh gate 20 can prevent debris from entering the ditch 3 and blocking the pipe. The main drainage pipe 21 is used to discharge water from the ditch 3 or introduce it into other areas. A plurality of branch drainage pipes 22 are arranged between the wire mesh gate 20 and the main drainage pipe 21. The inner diameter of the branch drainage pipe 22 can be selected as 75mm or 50mm as required to meet the requirements of different flow rates and flow rates.

[0047] A hollow water storage channel 23 is provided at the bottom of the internal road 4 and the road in the shed 13, which is beneficial to aquaculture.

[0048] In specific implementation, the indoor elevation of the vegetable greenhouse 2 is +0.7m to +1.0m, the bottom elevation of the ditch 3 is -2.5m to -1.5m, the bottom elevation of the rice field 1 is -0.3m, and the bottom elevation of the hollow water storage channel 23 under the internal road 4 and the road in the greenhouse 13 is -1.5m. Such elevation design is conducive to drainage and ventilation, and reduces water accumulation and moisture problems in agricultural production.

[0049] The internal passage is provided with an entrance and exit 24, which is used for small vehicles such as tricycles to enter and exit, so as to facilitate the transportation of agricultural products and the purchase of agricultural materials. The internal passage is made of cast-in-place slabs, which are strong and durable and have good load-bearing performance.

[0050] The concrete frame structure wall under the internal road, between the rice field and the ditch is built with hollow cement bricks. The five low sides of the first layer are filled with soil, and the four high sides of the first layer are empty, which are the nests of aquatic products (including turtles, soft-shelled turtles, crabs, etc.). The 40mm×40mm space between the hollow bricks is the nest of eels and loaches. It is the basis for ensuring the benign ecological cycle in this system.

[0051] In specific implementation, the proportion and layout of the vegetable greenhouse 2, the ditch 3, and the rice field 1 can be adjusted according to actual conditions. For example, in a unit of green circular agricultural system, the proportion of the vegetable greenhouse 2, the ditch 3, and the rice field 1 can be 3:2:5 for 50 mu; 2:1:7 for 100 mu; 1.5:1:7.5 for 200 mu; 1:1:8 for 500 mu, etc. Such proportion and layout can be flexibly adjusted according to local climate conditions, soil types, market demand and other factors to achieve the best agricultural production benefits and sightseeing tourism effects.

[0052] Embodiment 2

[0053] Based on the first embodiment, this embodiment optimizes and improves some details of the green circular agriculture system.

[0054] First, the design of the top sightseeing passage 15 and the solar photovoltaic panel 16 of the vegetable greenhouse 2 is optimized. The width and height of the sightseeing passage 15 can be adjusted according to actual conditions to meet the sightseeing needs and safety requirements of tourists. The inclination angle and layout of the solar photovoltaic panel 16 are also optimized to improve the utilization rate of solar energy and the power generation efficiency. Guardrails and rest seats can also be set on both sides of the sightseeing passage 15 to provide tourists with a more comfortable and safe sightseeing experience.

[0055] Secondly, the design of the flower pig breeding area 8 has also been improved. In addition to the flower pig jumping platform 18 and the feed inlet 19, an automatic feeding system and a drinking water system are also added in the flower pig breeding area 8 to reduce the labor intensity of manual feeding and improve feeding efficiency. At the same time, the ground of the flower pig breeding area 8 has also been hardened and paved with anti-slip materials to ensure the safety and health of the flower pigs.

[0056] In addition, the water inlet and outlet system 11 has also been optimized. A filter and a regulating valve are added between the wire mesh gate 20 and the main drainage pipe 21 to further prevent debris from entering the ditch 3 and clogging the pipe, and the flow rate and flow rate of the water flow can be adjusted as needed. At the same time, a water level monitoring system and an alarm device are also added to monitor the water level in the ditch 3 in real time and give an alarm in time when the water level is abnormal, ensuring the safety and stability of agricultural production.

[0057] In specific implementation, the planting and breeding varieties of the green circular agricultural system can also be selected and adjusted according to local climate conditions and market demand. For example, double-season rice or high-quality rice varieties can be planted in the rice field 1 to improve the yield and quality of rice; off-season vegetables or special vegetable varieties can be planted in the vegetable greenhouse 2 to meet the market demand for fresh vegetables; lean meat-type spotted pigs or special varieties of spotted pigs can be raised in the spotted pig breeding area 8 to improve the meat quality and taste of the spotted pigs.

[0058] The meat and aquatic products in this system are not fed with concentrated feed, but all with roughage (forage). The longer the growth cycle, the better the quality. We will be positioned as a supplier of high-quality agricultural products.

[0059] At the same time, we can also take advantage of the ecological advantages of the green circular agricultural system to develop ecological agricultural tourism projects. For example, we can set up ecological agricultural experience areas to allow tourists to experience agricultural production processes such as planting, breeding and agricultural product processing; we can set up ecological agricultural education areas to popularize ecological agricultural knowledge and environmental protection concepts to tourists; we can also set up ecological agricultural leisure areas to provide tourists with leisure services such as catering, accommodation and entertainment.

[0060] In the specific implementation, the following points should be noted:

[0061] Reasonable planning and layout: The layout of the green circular agricultural system should be rationally planned according to natural conditions such as terrain, climate, and soil to ensure coordination and complementarity among various functional areas.

[0062] Scientific management and operation: The management and operation of the green circular agricultural system should follow the principles of science, standardization and efficiency, establish a sound management system and operation mechanism, and ensure the stability and sustainable development of agricultural production.

[0063] Strengthen environmental protection: The green circular agricultural system should focus on environmental protection and ecological construction, take scientific and reasonable measures to reduce pollution and waste emissions, and protect the ecological environment and biodiversity.

[0064] Promote advanced technology: The green circular agricultural system should actively introduce and promote advanced agricultural technology and equipment, improve the scientific and technological content and added value of agricultural production, and enhance market competitiveness.

[0065] Strengthen talent training: The development of green circular agricultural systems requires the support of high-quality talents. We should strengthen talent training and introduction to improve the professional skills and comprehensive quality of agricultural practitioners.

[0066] In summary, the green circular agricultural system of the present invention realizes the organic integration of high-efficiency, ecological and sightseeing tourism functions of agricultural production through scientific and reasonable layout and advanced facility design. The system not only improves the utilization rate of agricultural land and agricultural production efficiency, but also meets the needs of modern people for leisure and tourism, and provides new ideas for the sustainable development of modern agriculture. In specific implementation, it can be flexibly adjusted and optimized according to actual conditions to achieve the best agricultural production efficiency and sightseeing tourism effect.

[0067] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
