The large-particle modifying agent is filled in the reticular shell 4, so that the modifying agent is not dissolved in the water body rapidly under the condition of ensuring that the water body can be fully contacted with the modifying agent particles, and the slow-release effect is achieved.
And step three, starting the aeration mechanism 2 to aerate the water body through the aeration pipe 3, fully mixing the water body, the oxygen and the modifying agent through aeration, and fully diffusing the modifying agent components gradually dissolved in the water body into the water body through air aeration.
It should be noted that although the water depth is shallow in the rice and shrimp farming environment, the application method of the water quality improver is still applicable because the purpose of the application method is to fill the particle improver in the shell 4 so as to be capable of gathering in the water to form a continuous diffusion source of the improver; the purpose of the aeration means 2 is to allow the agent in the casing 4 as the agent diffusion source to be sufficiently mixed in the water and diffused to all over the water, so that the aeration means 2 can employ a small-sized blower.
In addition, the use method of the water quality improver is not only suitable for the rice and shrimp farming environment, but also suitable for the deep water environment such as rivers and the like.
Example five:
in order to further improve the effectiveness of the modifying agent, in the second step, after the shell 4 is installed at the tail end of the aeration pipe 3, at least one branch pipe 5 is communicated with the part, close to the tail end, of the aeration pipe 3, a tank body 6 is installed at the tail end of the branch pipe 5, the branch pipe 5 is communicated with the interior of the tank body 6, the tank body 6 is connected to the floating island 1 through a chain, the surface of the tank body 6 is provided with meshes, the tank body 6 is also filled with the water modifying agent, and then the shell 4, the branch pipe 5 of the tank body 6 and the tail end of the aeration pipe 3 are all placed into water to enable the shell, the branch pipe 5 of the tank body and the tail end of the aeration pipe 3 to sink. The reason for filling the agent in the tank 6 is the same as that of the case 4,
meanwhile, in the third step, the aeration mechanism 2 is discontinuously started for aeration and the aeration mechanism 2 is closed for stopping aeration, when the aeration is stopped, the air pressure in the aeration pipe 3 is suddenly reduced, so that the water body flows through the tank body 6 through the branch pipe 5 and backflushes into the aeration pipe 3, and then flows back into the water body, and the diffusion effect of the modifying agent is further improved.
Example six:
on the basis of the fifth embodiment, in the second step, a movable plate 7 is arranged at the position where the branch pipe 5 is communicated with the aeration pipe 3, and when the aeration mechanism 2 performs aeration through the aeration pipe 3, the movable plate 7 closes the position where the branch pipe 5 is communicated with the aeration pipe 3; when the aeration mechanism 2 stops aeration, water backflushes to the branch pipe 5 and pushes the movable plate 7 to enter the aeration pipe 3, and then flows through the shell 4 from the aeration pipe 3 to flow back into the water, so that the water is prevented from flowing back from the branch pipe 5, and a smooth circulation loop is formed.
Repeated tests and analysis of results:
the rice and shrimp co-culture paddy field is set for testing, 6 test groups with the same area are randomly divided in the paddy field, and the area of each test group is half mu (namely 333 square meters). Every two groups are divided into 3 groups, and the first group is a blank control group; the second group is a test group 1, and the water quality modifier is used according to the dosage of 5kg per mu by adopting the using method of the invention; the third group is a test group 2, the water quality modifier is used according to the using amount of 10kg per mu by adopting the using method of the invention, the test period is 60 days, and the detection is carried out every 15 days. And (4) after the test period is finished, sampling and measuring the contents of total nitrogen, ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in water respectively, and detecting the heavy metal content in the lobster meat in the test field, wherein the results are shown in the following table.
The tests show that the contents of ammonia nitrogen and nitrite nitrogen in the water body can be effectively reduced, so that the water quality of the aquaculture water body is improved; but also can effectively reduce the content of heavy metals in the lobster meat and improve the quality of the lobsters. Meanwhile, the detection results of the test group 1 and the test group 2 in 4 detections carried out within 60 days are all changed within a very small range, so that the water quality modifier of the invention also has good sustained-release continuity.
In the test of the present invention, although each test group and the control group are located in the same paddy field, the intervals between the groups are far, and even if the agent in the test group is diffused into the control group or another test group with water, the influence is limited, and the principle of the test is that the modifying agent filled in the casing 4 or the tank 6 is used as a diffusion source, and the water quality improvement effect of the water body close to the diffusion source is naturally better, so that the strict limitation on the test field is not required.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
