Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
A lotus root-fish integrated ecological culture system is shown in figure 1 and comprises a hardening pool 10, wherein the hardening pool 10 is provided with a sludge layer 20 for lotus root growth and a water body layer 30 for fish life, the hardening pool 10 further comprises a nutrition pool 40 for providing nutrition required by lotus root fish growth, the nutrition pool 40 is communicated with the bottom of the water body layer 30 through a drain pipe 41, and the nutrition pool 40 is communicated with the top of the water body layer 30 through a water inlet pipe 42. The water at the lower part of the water body layer 30 enters the nutrition tank 40 through the drain pipe 41, is sent into the water body layer 30 after the nutrition adding and nutrition redistributing actions of the nutrition tank 40, and can impact the water body in the water body layer 30 and the sludge layer 20 at the bottom to a certain degree when entering the water body layer 30, so that the activity of the water body layer 30 is maintained, and the sludge layer 20 is properly turned and injected with oxygen.
Wherein, a filter element 41a is arranged in the drain pipe 41 to clean the water body to a certain degree.
In addition, the adding mode of the fish feed is designed to be intermittent adding to prevent the fish feed from being excessively input, namely, the fish feed feeding device 44 comprises a feed hopper 44a and an intermittent closing plate 44b arranged at the outlet of the feed hopper 44a, one end of the intermittent closing plate 44b is provided with a rack 51, the other end of the intermittent closing plate is provided with an elastic piece 52 connected with the wall of the nutrition pool 40, the rack 51 is meshed with a half-circumference gear 53 with teeth at the half circumference, and the half-circumference gear 53 is meshed with a driving gear 54. In the direction shown in fig. 1, the driving gear 54 rotates counterclockwise, which drives the half-cycle gear 53 to rotate clockwise, thereby driving the rack 51 and the intermittent closing plate 44b to move leftward, thereby opening the outlet of the feeding hopper 44a to allow the fish feed to fall into the feeding tank 40; when the half-cycle gear 53 rotates a certain angle, the part without the gear gradually approaches the rack 51, but cannot be meshed with the rack 51 to drive the intermittent closing plate 44b to move, so that the intermittent closing plate 44b returns to the outlet of the feed hopper 44a under the action of the elastic member 52 to close the outlet; when the portion of the half-gear 53 provided with the gear is rotated to above the portion not provided with the gear, the portion provided with the gear falls back to below due to the gravity of the gear to be engaged with the rack 51.
An inclined bottom layer 11 can be arranged at the bottom of the hardening pool 10, and the included angle between the bottom layer 11 and the side surface of the hardening pool 10 is 100-120 degrees; the sludge layer 20 is laid parallel to the bottom layer 11. The water outlet pipe 41 is arranged parallel to the bottom layer 11, and the nozzle of the water inlet pipe 42 is arranged above the highest point of the bottom layer 11 relative to the horizontal plane. Therefore, the interior of the hardening pool 10 can be divided into a shallow water area and a deep water area through the inclined bottom layer 11, moisture and nutrition in the shallow water area can flow to the deep water area under the natural action, and are automatically discharged into the nutrition pool 40 through the inclined drain pipe 41, the use of a water pump is reduced, and the effects of energy conservation and environmental protection are achieved. Then oxygen enrichment, fish feed addition and stirring redistribution are carried out in the nutrition pond 40, and the water returns to the shallow water area through the water inlet pipe 42, and the circulation is carried out, so that the energy is saved, the water activity is improved, and the growth environment of the lotus root fish is improved.
The nozzle of the water inlet pipe 42 can be connected with the spray head 42b through the bamboo joint pipe 42a, so that the nutrient water can be uniformly sprayed to any part of the hardening pool 10, and the uniformity of the nutrition in the hardening pool 10 is improved.
In order to improve the growth of lotus roots, appropriate top dressing is required to be carried out on the lotus roots, so that a top dressing pipe 21 is arranged in the sludge layer 20, and as shown in fig. 2, a plurality of fertilizer outlets are arranged on the pipe wall of the top dressing pipe 21. The top dressing pipe 21 comprises a plurality of concentric regular octagonal pipes 21a with sequentially regular large side lengths, the edges and corners of the regular octagonal pipes 21a are sequentially connected through a main pipe 21b, and a lotus root planting area is formed between the regular octagonal pipes 21a and the main pipe 21 b. The cobweb-shaped topdressing pipe 21 is directly buried in the sludge layer 20, and fertilizer is directly injected into the sludge layer 20 through a fertilizer outlet arranged on the pipe wall, so that the water body layer 30 is not polluted, and the growth environment of fishes is not influenced. The hardening pool 10 is partitioned by the topdressing pipe 21, so that the problem of nutrition competition caused by over crowding of the lotus root growth is prevented.
Meanwhile, in the hardening tank 10 provided with the inclined bottom layer 11, the fertilizer inlet of the topdressing pipe 21 is arranged at the highest point of the sludge layer 20 relative to the horizontal plane, and fertilizer can be automatically distributed in the whole topdressing pipe 21 under the action of gravity, so that the energy-saving effect is achieved.
In addition, the wall of the hardening pool 10 is provided with an overflow gap 12, when the water level of the water body layer 30 is too high, water can automatically overflow from the overflow gap 12, and the problems of waterlogging and the like caused by too high water level are prevented.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
