In order to increase the per-mu output value of the rice industry, rice breeding technology has emerged in recent years. By utilizing the spatial environment in rice fields, multi-variety aquaculture is carried out in a timely manner, thereby increasing the diversity of rice field agricultural products and aquatic products, thereby increasing the per-mu output value.

[0029] According to a first embodiment of the present invention, a method for controlling water in a rice field aquaculture is provided:
[0030] A method for controlling water in a rice field, the method comprising the following steps:
[0031] The oxygen distribution data and the water pH distribution data in the rice field are obtained, wherein the oxygen distribution data are the oxygen content in each area of the rice field, and the pH distribution data are the acidity and alkalinity of the water in each area of the rice field; based on the oxygen distribution data and the pH distribution data, the aquatic product distribution data in the rice field are analyzed and identified, wherein the aquatic product distribution data include: first area position data with low aquatic product density, second area position data with high aquatic product density, and third area position data with medium aquatic product density; based on the aquatic product distribution data, bait is placed in the first area of the rice field, and oxygen supply is increased in the second area of the rice field.
[0032] The present application provides a technical solution for a method for controlling water bodies in rice field aquaculture. In the technical solution, the distribution of aquatic products in the rice field is determined and identified by detecting the oxygen content distribution and pH value distribution of the water bodies in each small area of the rice field. Specifically, due to the rice planted in the rice field, the wind from the outside cannot directly act on the water surface, that is, the water body in the rice field is relatively static. In a relatively static water body, the oxygen consumption per unit time in the area with high aquatic product density is higher than that in the area with low aquatic product density, so the oxygen content in the area with high aquatic product density is lower than that in the area with low aquatic product density; at the same time, the present application also determines the distribution of aquatic products by measuring the pH value of each local area. That is, the respiration or metabolism of aquatic products produces acidic substances that are discharged into the rice field, making the water body in the rice field acidic. In a relatively static water body, the amount of acidic substances produced per unit time in the area with high aquatic product density is higher than that in the area with low aquatic product density, so the pH value in the area with high aquatic product density is lower than that in the area with low aquatic product density. By comprehensively analyzing the oxygen distribution data and the water pH distribution data in the rice field, the distribution data of aquatic products in the rice field with high accuracy can be obtained. The aquatic product distribution data is divided into: the first area position data with low aquatic product density, the second area position data with high aquatic product density, and the third area position data with medium aquatic product density, which can better distinguish the distribution density types of aquatic products and facilitate control and management. Based on the aquatic product distribution data, by putting bait into the first area position in the rice field, the aquatic products around it can enter the first area position, which plays a role in controlling the uniform distribution of aquatic products in the rice field, achieving the purpose of promoting the uniform development of aquatic products, improving the balance of development in aquatic products, and improving product quality; by increasing the oxygen supply to the second area position in the rice field, it can ensure that the aquatic products at the second area position are adequately supplied with oxygen, and prevent the occurrence of aquatic product reduction caused by hypoxia. In summary, the technical solution provided by this application can effectively improve the quality uniformity of aquatic products cultured in rice fields, reduce the damage rate of aquatic products, and improve production efficiency and quality.
[0033] Specifically, in an embodiment of the present invention, the "obtaining oxygen distribution data and pH distribution data in a rice field" includes the following steps: introducing oxygen and weakly alkaline water into the rice field; performing a first real-time data collection on the rice field, collecting oxygen content data and pH data of each area in the rice field, and obtaining first oxygen distribution data and first pH distribution data; when the oxygen content data of each area of the rice field in the first oxygen distribution data are consistent, stopping the introduction of oxygen; when the pH data of each area of the rice field in the first pH distribution data are consistent, stopping the introduction of weakly alkaline water; after standing for a period of time, performing a second data collection on the rice field to obtain oxygen distribution data in the rice field and water pH distribution data.
[0034] It should be noted that the problem to be solved in this embodiment is how to accurately collect and obtain "oxygen distribution data and pH value distribution data in rice fields" and then accurately obtain "aquatic product distribution data in rice fields".
[0035] In this embodiment, "oxygen and weak alkaline water are introduced into the rice field in advance" until "the oxygen content data of each area of the rice field in the first oxygen distribution data are consistent", then the introduction of oxygen is stopped; until "the pH value data of each area of the rice field in the first pH distribution data are consistent", then the introduction of weak alkaline water is stopped; the above steps ensure that the water in each area of the entire rice field maintains the same oxygen content and pH value data; after a period of standing, such as: 10 to 200 minutes, the second data collection is performed on the rice field; and then accurate "oxygen content distribution data in the rice field and water pH value distribution data" are obtained.
[0036] This embodiment can eliminate the errors in collecting and detecting the oxygen content and pH value of paddy field water, and improve the control accuracy of the entire solution.
[0037] To explain specifically, in an embodiment of the present invention, the "obtaining oxygen content distribution data and pH value distribution data in the rice field" includes the following steps: stirring the water in the rice field; after standing for a period of time, performing a second data collection on the rice field to obtain oxygen content distribution data and pH value distribution data in the rice field.
[0038] It should be noted that another implementation method is provided to solve the technical problem of how to accurately collect and obtain "oxygen distribution data and pH value distribution data in rice fields" and then accurately obtain "aquatic product distribution data in rice fields".
[0039] In this embodiment, the oxygen content and pH value of each area in the rice field are kept consistent by directly stirring the water in the rice field. After a period of standing, such as 10 to 200 minutes, the second data collection is performed on the rice field to obtain accurate "oxygen content distribution data and water pH value distribution data in the rice field".
[0040] This embodiment can also eliminate the errors in collecting and detecting the oxygen content and pH value of the water in the rice field, thereby improving the control accuracy of the entire solution.
[0041] Specifically, in an embodiment of the present invention, the “muddying the water in the rice field” includes the following steps: extracting rice field water from one side of the same rice field, and injecting the rice field water into the other side of the same rice field.
[0042] It should be noted that the problem to be solved in this embodiment is: how to "muddy the water in the rice field".
[0043] By extracting water from one side of the rice field and injecting it into the other side, a certain effect of muddying the water in the rice field can be achieved.
[0044] Furthermore, the method of “muddying the water in the rice field” also includes another implementation scheme, performing the following steps:
[0045] The paddy field water is extracted from the middle of the paddy field; the water is injected into the paddy field through the water injection device arranged on the ridges around the paddy field, and the water injection direction deviates from the center of the paddy field.
[0046] Specifically, in an embodiment of the present invention, the method further includes the following steps: setting a fish pond in a rice field; extracting a first water body from the bottom of the fish pond; and injecting the first water body into a first area of the rice field.
[0047] It should be noted that by setting up a fish pond in the rice field, the comprehensive utilization efficiency of the nutrients in the rice field can be effectively improved. At the same time, since a large amount of fish excrement is precipitated at the bottom of the fish pond, it can be beneficial to the growth of rice. By passing the first water body at the bottom of the fish pond into the rice field, the waste of the fish pond can be reused.
[0048] In addition, using the nutrients at the bottom of the fish pond to attract crayfish in the rice field is one of the innovations of this embodiment. By putting the nutrients at the bottom of the fish pond into the first area, the aquatic products (crayfish in the rice field) at the second area can be attracted to migrate in the rice field, thereby promoting the uniform distribution of aquatic products in the rice field.
[0049] Specifically, in an embodiment of the present invention, the method further includes the following steps: extracting a second water body from a first area position in the rice field; and introducing the second water body from the second area position toward the first area position.
[0050] It should be noted that, in the present embodiment, since bait or the first water body has been put into the first area, the bait is abundant in the first area; by extracting the second water body at the first area and putting the second water body into the second water body from the second area toward the first area, the aquatic products in the second area with a high density of aquatic products are further guided into the first area, thereby better realizing the uniform distribution of aquatic products inside the rice field.
[0051] To explain specifically, in an embodiment of the present invention, the method also includes the following steps: obtaining weather forecast data and current temperature data; when the current temperature data is lower than a first temperature threshold; obtaining a third water body from the center of the rice field; putting bait at the edge of the rice field; and injecting the third water body from the edge of the rice field into the center of the rice field.
[0052] It should be noted that the problem that the present application needs to solve is "how to control the unified movement of aquatic products inside the rice fields before or when the temperature changes, in combination with the developmental characteristics of aquatic products, to avoid the aquatic products in the rice fields being exposed to cold or heat", thereby improving the quality of aquatic products in the rice fields.
[0053] By obtaining weather forecast data and current temperature data, when the current temperature data is lower than the first temperature threshold, it means that the area where the rice field is located is about to enter a low temperature state, and aquatic products need to be introduced into the rice field to improve the cold resistance of aquatic products. Specifically, the third water body is obtained from the center of the rice field, and the third water body is injected from the edge of the rice field to the center of the rice field, driving the bait placed at the edge, and then guiding the aquatic products from the edge of the rice field into the interior of the rice field.
[0054] To explain specifically, in an embodiment of the present invention, the method also includes the following steps: when the current temperature data is higher than the second temperature threshold, obtaining a fourth water body from the edge of the rice field; putting bait in the center of the rice field; and injecting the fourth water body from the center of the rice field into the center of the rice field.
[0055] It should be noted that in order to solve the above problem, the present embodiment also includes obtaining a fourth water body from the edge of the rice field when the current temperature data is higher than the second temperature threshold, and injecting the fourth water body from the middle of the rice field to the edge of the rice field, and at the same time putting bait in the middle of the rice field to promote aquatic products to enter the edge of the rice field from the rice field when the temperature is high.
[0056] According to a second embodiment of the present invention, a rice field aquaculture water control system is provided:
[0057] A rice field aquaculture water control system, the system comprising:
[0058] A first acquisition module for acquiring oxygen distribution data in a rice field; a second acquisition module for acquiring pH value distribution data of water in a rice field; a first analysis module for analyzing and identifying aquatic product distribution data in a rice field based on the oxygen distribution data and the pH value distribution data; a first execution module for placing bait in a first area of a rice field based on the aquatic product distribution data; a second execution module for increasing oxygen supply to a second area of a rice field based on the aquatic product distribution data.
[0059] The present application also provides a rice field aquaculture water control system, which is used to execute the control method described in the first embodiment and has the same technical effects as the first embodiment.
[0060] According to a second embodiment of the present invention, a rice field aquaculture water control system is provided:
