Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological farming technology, specifically to an intelligent combined system for container farming and rice paddy ecological farming. Background Technology
[0002] Rice-fish farming is an agricultural production model that combines rice cultivation with aquaculture within the same paddy field. In this model, the animals not only prey on rice pests and pathogens, reducing the risk of rice diseases and pests, but their excrement also serves as organic fertilizer, improving soil fertility and reducing the use of chemical fertilizers. This lowers production costs and reduces the risk of environmental pollution, resulting in high economic and ecological benefits. However, to meet the needs of the animals, rice-fish farming typically requires a water depth of 10–25 cm, significantly higher than the 5–10 cm water depth in conventional monoculture paddy fields. This means that implementing rice-fish farming significantly increases the water demand of the paddy fields.
[0003] Container aquaculture is a new type of intensive, facility-based aquaculture method that utilizes the enclosed space of a shipping container for the efficient farming of aquatic animals such as fish and shrimp. This method not only effectively controls the aquatic environment, reducing disease transmission and animal mortality, but also enables precise feeding and water quality monitoring through intelligent equipment, greatly improving farming efficiency. While container aquaculture has the advantages of saving land resources and not being limited by traditional water bodies, the limited and enclosed space inside the container results in weak water self-purification capabilities, necessitating frequent water changes or replenishments to maintain good water quality. This means that container aquaculture consumes a significant amount of water resources. Statistics show that the water consumption of a single container during a farming period is approximately 2.25 × 10⁻⁶. 4 m 3 .
[0004] Discharging container aquaculture wastewater into paddy fields for use in rice-fish farming systems is a novel comprehensive water resource utilization solution. This method not only solves the problem of container aquaculture wastewater treatment but also provides a large amount of water and nutrient resources for rice-fish farming. Simultaneously, paddy fields efficiently remove nutrients from the aquaculture wastewater through soil adsorption, rice root absorption, and microbial decomposition. However, the water purification capacity of paddy field ecosystems is limited and requires a certain amount of time to absorb the wastewater. Improper discharge of container aquaculture wastewater may disrupt the water balance and water quality stability of the paddy field ecosystem, affecting the growth and survival of rice and animals, and consequently impacting the economic benefits of the paddy field ecosystem. Therefore, rationally managing the relationship between container aquaculture wastewater and rice-fish farming systems to achieve energy and ecological balance and ensure sustainable production is of great significance. Summary of the Invention
[0005] To overcome the aforementioned defects and shortcomings in the existing technology, this utility model provides an intelligent integrated system for container farming and rice paddy ecological farming.
[0006] This utility model is achieved through the following solution:
[0007] A system combining container aquaculture and rice-field ecological farming includes one container fish farming facility and n rice fields, where n is 2 to 6;
[0008] The containerized fish farming facility is equipped with a main drainage pipe, and a main valve is installed on the main drainage pipe;
[0009] The outlet end of the main drainage pipe is connected to the n paddy fields through a corresponding number of outflow pipes;
[0010] Each of the water outlet pipes is equipped with a valve.
[0011] Because the water purification capacity of paddy field ecosystems is limited and requires a certain amount of time to be absorbed, discharging container aquaculture wastewater into paddy fields for use in the paddy field ecological farming system can lead to water environment imbalance in the paddy field ecosystem if the wastewater is not properly discharged. This can affect the survival and growth of rice and aquatic animals, and consequently, the economic benefits of the paddy field ecosystem. This invention, through experimental observation and data calculation, demonstrates that when there are 2 to 6 paddy fields, controlling the discharging of container aquaculture wastewater into n paddy fields in a timely manner according to demand via a main valve and other valves can effectively balance the wastewater discharge, the water capacity and purification volume of the paddy field ecological farming system, thereby achieving green, ecological, efficient, and integrated rice-fish farming.
[0012] Preferably, n = 4, and the area of the paddy field is 2 to 2.5 mu per plot.
[0013] Preferably, the water volume of the containerized fish farming facility is 20-25 m³. 3 .
[0014] Preferably, the number of paddy fields is four. Due to the large size of the containerized fish farming facilities, and for the rational use of land resources, and for convenience and energy conservation considerations, the paddy fields and containerized fish farming facilities can be arranged in the following more preferably manner:
[0015] The four paddy fields are arranged adjacent to each other to form one paddy field unit, and the container fish farming facility is set around the paddy field unit.
[0016] Alternatively, the four paddy fields may be arranged in a cross shape, with the containerized fish farming facility positioned at the center of the cross formed by the four paddy fields.
[0017] Alternatively, the four paddy fields may be arranged in a cross shape to form one paddy field unit, and the containerized fish farming facility may be set up around the paddy field unit.
[0018] Preferably, the containerized fish farming facility is also equipped with a tailwater drain outlet and a tailwater drain pipe, and the tailwater drain pipe is equipped with a valve.
[0019] Preferably, the containerized fish farming facility is also equipped with an intelligent water quality monitoring instrument to monitor water temperature, pH, ammonia nitrogen, and dissolved oxygen in real time to ensure the stability of the aquaculture water.
[0020] Some container aquaculture wastewater is discharged through wastewater outlets and wastewater pipes under the following circumstances:
[0021] During the rice's greening and early tillering stages, the amount of wastewater discharged from container aquaculture exceeds the demand of the paddy fields.
[0022] Or, during the later stages of rice growth, the water requirement gradually decreases;
[0023] Or, during rainy days with heavy rainfall, the paddy fields can only accommodate a portion of the container discharge wastewater from aquaculture.
[0024] Under the following circumstances, all wastewater from container aquaculture will be discharged through the wastewater outlet and wastewater pipe:
[0025] Draining and drying rice paddies;
[0026] Or, during rainy days with heavy rainfall, the paddy fields cannot accommodate the discharge of aquaculture wastewater from containers.
[0027] Preferably, the containerized fish farming facility is also equipped with an air inlet for oxygenation, which ensures that the dissolved oxygen in the water is higher than 6 mg / L, thereby avoiding the excessive levels of nitrite and ammonia nitrogen in the water caused by insufficient dissolved oxygen, which could induce fish diseases and affect the yield of the rice-fish farming system.
[0028] In order to automate the discharge of wastewater from container aquaculture and to simplify production through intelligent interconnection systems, it is preferable that the main valve is equipped with an automatic drainage device, the valve on the outlet pipe is an automatic valve, and the automatic valve is equipped with an automatic drainage device.
[0029] Compared with the prior art, the present invention has the following beneficial effects:
[0030] This utility model discloses an intelligent integrated system for container aquaculture and rice-field ecological farming. This system effectively coordinates the wastewater discharge from container aquaculture with the water capacity of the rice-field ecological farming system, while also achieving intelligent and optimized irrigation management of the rice paddies. This significantly improves the utilization rate of nutrients and water resources, as well as the yield of agricultural products from the farmland ecosystem. Simultaneously, the rice-field ecosystem also plays a role in purifying water quality, effectively absorbing and utilizing nitrogen and phosphorus nutrients from the aquaculture wastewater, thus avoiding environmental pollution caused by direct discharge of aquaculture wastewater. Therefore, this integrated system represents a highly efficient, clean, and green model of intensive container aquaculture and rice-field ecological farming, possessing significant ecological and socio-economic value.

[0037] The present invention will be further described below with reference to specific embodiments, but the embodiments do not limit the present invention in any way. Unless otherwise specified, the reagents, methods and equipment used in the present invention are conventional reagents, methods and equipment in this technical field.
[0038] Unless otherwise specified, all reagents and materials used in the following examples are commercially available.
[0039] The container fish farming facility is a land-based push-flood container aquaculture system of Guangzhou Guanxing Agricultural Technology Co., Ltd. The standard container size is 6.058m (L) × 2.438m (W) × 2.896m (H), and the bottom surface of the container is designed with a longitudinal slope of 5° to 10°.
[0040] Example 1: An intelligent integrated system for container farming and rice paddy ecological farming
[0041] The combined system includes containerized fish farming facilities. Figure 1 ), rice paddies and drainage pipes, such as Figure 2 and Figure 3 As shown.
[0042] The 10 mu paddy field was divided into four plots of 2.5 mu each (40.8m×40.8m) (6). The four plots (6) were arranged adjacent to each other, and the width of the ridge between each pair of plots was 0.5m.
[0043] A containerized fish farming facility (1) is set up around the rice paddy. The containerized fish farming facility (1) includes a water inlet (111), an air inlet (112), a drainage outlet (115), and a fish outlet (116). The container dimensions are 6.058m (length) × 2.438m (width) × 2.896m (height). The capacity of the containerized fish farming facility (1) is 25m³. 3 The top of the tank is equipped with a skylight (113) for feeding and light transmission. Inside, there is an intelligent water quality monitor (114) for real-time monitoring of water temperature, pH, ammonia nitrogen, and dissolved oxygen to ensure the stability of the aquaculture water. The tank is also equipped with a tailwater drain outlet (117) and a tailwater drain pipe (118), and an automatic valve (not shown in the figure) is installed on the tailwater drain pipe (118).
[0044] The bottom of the container is sloped to one end at a certain angle, with a slope of 5° to 10°. The side of the container is provided with a fish outlet (116) for quick fish collection, and a drain outlet (115) is connected to the main drain pipe (2). The main drain pipe (2) is equipped with a main valve (4), which controls the discharge of aquaculture wastewater (a mixture of water, aquatic excrement and uneaten feed).

[0051] When four fields need to be flooded more deeply or drained and then re-flooded, the main valve (4) on the main drainage pipe (2) and the automatic valve (5) on the outflow pipe (3) connected to each field are opened simultaneously until the target water level is reached.
[0052] Under the following circumstances, some container aquaculture wastewater is directly discharged through the wastewater outlet (117) and wastewater outlet (118):
[0053] During the rice's greening and early tillering stages, the amount of wastewater discharged from container aquaculture exceeds the demand of the paddy fields.
[0054] Or, during the later stages of rice growth, the water requirement gradually decreases;
[0055] Or, during rainy days with heavy rainfall, the paddy fields can only accommodate a portion of the container discharge wastewater from aquaculture.
