Description
Technical Field
The invention relates to the field of water environment treatment, in particular to a treatment method of ampullaria gigas in a landscape water body.
Background
The ampullaria gigas are native to amazon river basin in south america, introduced into china in 1981, and propagated as food materials in the guangdong after 1984. Due to excessive cultivation and bad taste, the feed is released to the field in large amount. Since the ampullaria gigas is a foreign species, the ampullaria gigas has few natural enemies in China, and the climatic conditions are very favorable for the growth and reproduction of the ampullaria gigas. The peak period of spawning and hatching of the ampullaria gigas is 4-6 months and 8-10 months every year, the ampullaria gigas can grow into adults in 2-3 months, 200 eggs are produced once, secondary spawning is carried out after 3-5 days, 20-40 eggs can be produced in one year, and the egg production amount is 3-5 ten thousand. The ampullaria gigas eggs need to be hatched for 10 to 15 days in the air, break membranes and then come out after the ampullaria gigas develop, and fall into water. Crops such as rice, astragalus sinicus, arrowhead, semen euryales, sweet potatoes, vegetables and the like are main targets of the damage to the ampullaria gigas, the damage to the rice is particularly serious, the ampullaria gigas almost generate the damage in the whole growth period of the rice, and the yield of the rice is reduced. Therefore, ampullaria gigas has been listed as one of the first 16 most harmful foreign species invading China.
The Pomacea canaliculata has strong environmental adaptability and high propagation speed, not only spreads in large areas in rivers, lakes and fields, but also shows an outbreak situation in landscape water bodies such as parks, scenic spots and the like. Not only a large amount of aquatic plants in the landscape water body are eaten by silkworms, but also the ecological balance of the landscape water body is broken, so that the water body environment is deteriorated; in addition, a large number of eggs lay around the landscape water body, such as the bank wall of a water pool, the bank side of an artificial lake and the like, and the visual effect of the landscape water body is influenced.
At present, the ampullaria gigas in the landscape water body are mainly treated by artificial fishing, and the spawn is also mainly treated by artificial shoveling, collecting and centralized processing. The method has poor treatment effect and low treatment efficiency, and is difficult to achieve the purpose of effective control on the ampullaria gigas with extremely strong fertility and extremely high propagation speed. The chemical molluscicide is also used for preventing and treating the molluscicide, but has the disadvantages of large application amount, high cost, poor effect, high toxicity to water, serious water pollution and water ecology damage.

s3: the water inlet of the landscape water body is provided with a blocking net, so that the ampullaria gigas outside the landscape water body are prevented from entering the landscape water body, and the ampullaria gigas inside the landscape water body are prevented from escaping out of the landscape water body;
s4: putting procambarus clarkii into the landscape water body;
s5: and putting the black carps in the landscape water body.
Furthermore, the scouring mechanism comprises pipelines which are continuously arranged along the periphery of the landscape water body, and scouring heads are densely distributed on the pipelines.
Furthermore, the water outlet of the flushing head on the pipeline is 6-10 cm away from the water surface.
Furthermore, the number of the turnover mechanisms is at least one, and the mutual distance is 10-30 meters.
Further, the overturning part is a rockery or an ecological floating island.
Further, the height of the part of the overturning part which is immersed in the water is always equal to that of the part which is exposed out of the water surface.
Further, the putting amount of the procambarus clarkii is 5-10 in water every 10 m.
Further, the put amount of the black carp is 5-10 in 10m water for cultivation.

Further, the method also includes step S7: a water pumping mechanism is arranged in the landscape water body, and the water pumping mechanism is communicated with a pipeline of the flushing mechanism; the water pumping mechanism comprises a water pump, a water pumping pipe and a filter screen arranged at the bottom of the water pumping pipe; and at night, the water pumping mechanism is started to pump water in the landscape water body into the scouring mechanism and scour the bank wall of the landscape water body from the scouring head.
Compared with the prior art, the invention has the following beneficial effects:
1. according to the invention, the scouring mechanism is arranged around the landscape water body, and since the ampullaria gigas spawning is carried out at night and has to leave the water surface, the scouring mechanism is started to flush water at night, so that the ampullaria gigas can be prevented from climbing above the water surface, and the ampullaria gigas can not spawn on the bank wall of the landscape water body.
2. According to the invention, the turnover mechanism is arranged in the landscape water body, and the Procambrus clarkii is thrown in the turnover mechanism, so that the ampullaria gigas cannot lay eggs on the bank wall of the landscape water body, and are inevitably concentrated on the turnover mechanism to lay eggs at night, and the turnover mechanism is turned over in the next morning, so that the laid eggs can be submerged in water, and meanwhile, the Procambrus clarkii raised in the water can eat a large amount of eggs of the ampullaria clarkii.
3. The invention puts the black carps in the landscape water body, the black carps are inhabited in the middle and lower layers of the water body, generally do not swim to the water surface, the feeding performance is simple, and mollusk snails and corbicula fluminea are taken as main food, so that the invention can prey on a large number of ampullaria gigas, thereby reducing the number of the ampullaria gigas.
4. According to the invention, the blocking nets are respectively arranged at the water inlet and the water outlet of the landscape water body, so that the external ampullaria gigas can be effectively blocked from entering, and the ampullaria gigas can be effectively prevented from escaping, and therefore, the ampullaria gigas can be killed to the maximum extent.
In conclusion, aiming at the characteristic that ampullaria gigas eggs cannot normally develop in water and can be laid on the bank wall or other objects with a certain height from the water surface to breed offspring, the ampullaria gigas cannot normally lay eggs on the bank due to the arrangement of the flushing mechanism on the bank wall of the landscape water body, and the eggs laid on the ampullaria gigas can be conveniently immersed into the water due to the arrangement of the turnover mechanism in the water body. The two are mutually matched to cut off the breeding way of the ampullaria gigas. The method comprises the following steps of putting black carps in a landscape water body by utilizing the characteristic that the black carps are relatively simple in feeding property and mainly take mollusk snails and corbicula fluminea as food, and controlling the number of ampullaria gigas; meanwhile, aiming at the habit that the black carps mainly live in the middle and lower layers of the water body and generally do not swim to the water surface, the problem that the upper water surface is difficult to care by only throwing the black carps is solved by throwing the ampullaria gigas which preys on the upper water surface and eggs laid by the ampullaria gigas.
In a word, on one hand, the invention blocks the reproduction of ampullaria gigas and controls the newly increased number of ampullaria gigas; on the other hand, the existing number of ampullaria gigas is gradually reduced through the cooperation of the black carps and the procambarus clarkia. The invention not only greatly reduces the workload of manual treatment, does not use chemical agents, but also can quickly and long-term control the adverse effects of the ampullaria gigas and maintain the excellent environment and landscape effect of the landscape water body.

Through the means, after 1 month of treatment, red egg masses of ampullaria gigas cannot be seen on the artificial lake shore wall 1 and the ecological floating island completely; after 3 months, the egg-laying peak season under ordinary conditions is entered, but red egg masses are still not seen on the artificial lake bank wall 1, and only 1-2 egg masses can be seen on the ecological floating island every week.
Example three:
the method of the invention is adopted to treat the artificial lake in a certain scenic spot in Leshan City. The artificial lake is an oblong water pool, and the distance between the lake banks at the two ends is about 120 m. The density of the ampullaria gigas in the artificial lake is high, and red egg masses produced by the ampullaria gigas are attached to the bank wall 1 for a long time, so that the normal ecology of the artificial lake is greatly damaged, and the attractiveness of the lake bank is also influenced. Specially-assigned people are arranged in scenic spots throughout the year to catch ampullaria gigas, egg masses are collected and concentrated, the treatment effect is limited, and the catching speed is far lower than the breeding speed of the ampullaria gigas. The treatment is carried out by putting fishes predating ampullaria gigas, but the effect is not obvious.
For the artificial lake, the technical scheme of the invention is adopted to treat ampullaria gigas, and the specific implementation conditions are as follows:
s1: arranging a flushing mechanism 2 on the artificial lake, specifically arranging a continuous pipeline 22 along the wall 1 of the artificial lake, densely distributing downward flushing heads 21 on the pipeline 22, and enabling the flushing heads 21 to be 8cm away from the water surface; the pipeline 22 is communicated with a water pump 23, the other end of the water pump 23 is connected with a water pumping pipe 24, the bottom of the water pumping pipe 24 is provided with a filter screen 25, and the water pumping pipe 24 extends into the water pool. At night, a water pump 23 is started, the water pump 23 pumps water from the water pool and pumps the water out through a flushing brush head 21 on a pipeline 22 around the quay wall 1, and the ampullaria gigas climbing up the quay wall 1 are flushed and flushed back to the water pool, so that the ampullaria gigas are prevented from spawning on the quay wall 1;
s2: a plurality of turnover mechanisms 3 are arranged at the artificial lake, and one turnover mechanism is arranged at intervals of 20 m. The turnover mechanism 3 comprises a supporting part 32, a fixing part 31 and a turnover part 30, wherein the turnover part 30 is an ecological floating island which is made into a symmetrical structure, the ecological floating island is supported by the supporting part 32 which is erected at the bottom of the pool, the supporting part 32 is two upright posts, the fixing part 31 is arranged between the two upright posts, the fixing part 31 is rotatably connected with the upright posts, and the ecological floating island is fixed on the fixing part 31. One half of the ecological floating island is submerged in water, and the other half of the ecological floating island is exposed out of the water surface. Enabling the ampullaria gigas to climb up the part of the ecological floating island exposed out of the water surface at night to lay eggs, and turning over the ecological floating island every morning to immerse the laid eggs into the water;
s3: an iron wire barrier net 13 is arranged at a water inlet 11 of the artificial lake, the aperture of meshes is 2cm, so that external ampullaria gigas are prevented from entering, and internal ampullaria gigas are prevented from escaping;
s4: putting the Procambrus clarkii into the water pool, putting 8 Procambrus clarkii into water every 10m, and automatically taking the ampullaria gigas and egg masses which eat the upper water body;
s5: and (3) putting the black carps into the water pool, and putting 8 black carps into the water during each 10m of cultivation, wherein the black carps automatically prey the ampullaria gigas in the middle-lower water body.
S6: an iron wire separation net 13 is arranged at the water outlet 12 of the water pool, the aperture of the mesh is 2cm, the ampullaria gigas are prevented from escaping, and meanwhile, the external ampullaria gigas are prevented from entering.
By the means, after one and a half months, red egg masses of ampullaria gigas cannot be seen on the artificial lake wall 1 and the ecological floating island completely; after entering the spawning peak period under the ordinary condition, red egg masses can still not be seen on the artificial lake bank wall 1 and the ecological floating island.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
