TECHNICAL FIELD

[0001] The present application relates to the technical field of rice field frog catching, in particular to a rice frog unified catching system and a catching method. BACKGROUND

[0002] The rice field frog symbiotic system is an ecological agricultural system integrating rice cultivation and rice field frog cultivation. This system realizes mutual symbiosis between the two by utilizing the ecological environment of the rice field and the biological characteristics of the rice field frog. The rice field frog is a carnivorous animal that mainly feeds on pests such as aphids, mosquitoes, and locusts. The rice field frog can effectively control the number of pests and reduce the harm to rice cultivation, thereby reducing the amount of pesticide used. The excrement of the rice field frog is rich in organic matter and nutrients, which can be used as natural fertilizer for the rice field. When the rice field frog moves in the rice field, it releases excrement to provide nutrients for rice cultivation and promote the growth and development of rice cultivation.

[0003] Therefore, the rice field frog symbiotic system can effectively reduce the amount of pesticide used, reduce production costs, and improve the ecological benefits of the rice field.

[0067] Embodiment 1:

[0068] As shown in Figures 1 to 7 , a unified fishing system for rice frogs includes: ​​

[0069] fishing net 1, fishing rope 2 and several columns 3;

[0070] The fishing net 1 is laid around the feeding area 40 on the rice field 4, the end A of the protective net 5 arranged on the fishing net 1 close to the edge of the rice field 4 is connected with the protective net 5, the end B of the fishing net 1 laid on the feeding area 40 is arranged to be freely tensioned, the width D1 and the length L1 of the fishing net 1 and the width D2 and the length L2 of the feeding area 40 satisfy the relationship: D1>D2, L1>L2;

[0071] The fishing rope 2 is arranged along the length direction of the fishing net 1 and is arranged in the freely tensioned end B of the fishing net 1, the fishing rope 2 is pulled to drive the end B of the fishing net 1 to be lifted;

[0072] The columns 3 are arranged equidistantly on the end B of the fishing net 1 along the length direction of the fishing net 1, the columns 3 support the fishing rope 2 and provide support points for the pulling and tensioning of the fishing rope 2.

[0073] The width D1 of the fishing net 1, the width D2 of the feeding area 40 and the height h of the protective net 5 satisfy the relationship: D1≥D2+h.

[0074] Further, the number of the columns 3 is n, the height of the columns 3 is H, n, H, the length L3 of the fishing rope 2 and the length L2 of the feeding area 40 satisfy the relationship: L3≥L2+2nH.

[0075] In addition, the columns 3 include a support column 31 and a limiting ring 32;

[0076] The support column 31 is vertically arranged, and the lower end thereof is arranged to be sharp;

[0077] The limiting ring 32 is arranged on the top of the support column 31, the limiting ring 32 is used for penetrating the fishing rope 2 and limiting the ring direction of the fishing rope 2.

[0078] Specifically, the length of the rice field 4 is within 60 m, the width is 15-18 m, the central part of the breeding pond 4 is excavated to have a drainage ditch with a width of 50 cm and a depth of 30 cm, a water retaining dam is built between the adjacent two breeding pond blocks, the width of the water retaining dam is about 0.8 m, a feeding area 40 is reserved at the edge, the area ratio of the feeding area 40 does not exceed 10% of the area of the rice field 4, and the area of the seedling planting area accounts for more than 90% of the area of the rice field 4. The rice field 4 must be designed and built according to a three-layer stepped structure, preferably, the height of the water retaining dam of the rice field 4 is higher than that of the feeding area 40 by 4 cm, the height of the feeding area 40 is higher than that of the planting area by 15-18 cm, the height of the planting area is higher than that of the middle drainage ditch by 30 cm, and the protective net 5 with a net height of 80 cm is arranged around the rice field 4, and the protective net 5 is made of 50-mesh brand-new polyethylene mesh cloth.

[0079] First of all, it needs to be noted that the height of the feeding area 40 in the rice field 4 is higher than the soil height of the rice planting area in the rice field 4, because when the rice is planted in the rice field, water needs to be stored to keep the soil moist, and if the horizontal height of the feeding area 40 is the same as or lower than the soil surface of the rice field 4, the water in the rice field will infiltrate the rice frog bait in the feeding area 40, causing the bait to disperse in water and not available for the rice frog to eat, therefore, the height of the feeding area 40 is higher than the height of the rice field, specifically, the height of the feeding area 40 is generally about 15-18 cm higher than the planting area 15 in the rice field 4, and the rice frog will actively climb to the feeding area 40 to find a landing point when the water in the rice planting area is more than 10 cm above the water surface, because the rice frog does not like to stay on the water surface for a long time. Therefore, after the rice field is filled with water, the rice frog will actively move to the relatively dry feeding area, and due to the previous feeding habits, the rice frog will concentrate in the feeding area 40 for feeding at feeding time, which facilitates the concentrated capture of the rice frog in the feeding area 40 by the present application.

[0080] Before the feeding time, the fishing net 1 is laid on the feeding area 40, so that the end A of the fishing net 1 is connected with the top of the protective net 5, and the end B of the fishing net 1 is located between the feeding area 1 and the rice field 4, then the support column 3 is inserted at a certain distance along the end B of the fishing net 1 one by one, after the installation of the support column 3 is completed, the fishing rope 2 is then threaded through the end B, the end B is provided with a circular ring for the fishing rope 2 to pass through, and the fishing rope 2 is sequentially threaded through the circular ring on the fishing net 1 and the limiting ring 32 on the support column 3, after the threading of the fishing rope 2 is completed, water is poured into the rice field 4, as the water in the rice field 4 continues to be poured, once the water level reaches more than 10 cm above the water surface in the rice planting area, the rice frog will continuously move from the planting area of the rice field 4 to the feeding area 40, and the bait is pre-placed in the feeding area 40, which can attract and retain the rice frog in the feeding area 40, after the rice frog concentrates in the feeding area 40, the end B is lifted by pulling the fishing rope 2, and a fishing area for limiting the rice frog is formed between the end B and the end A, and then the capture is concentrated.

[0081] Specifically, the mesh diameter of the fishing net 1 is 2 cm, the width of the fishing net 1 is preferably about 3:1 of the width of the feeding area 40, the width of the fishing net 1 is 3.5 meters, and the length is preferably about 1 meter longer than the length of the feeding area 40, the length is customized according to the length of the self-site breeding pond, generally within 100 meters, and the mature rice frog has a weight of 40g-100g.

[0082] It is worth emphasizing that the upper part of the limiting ring 32 is provided with a notch 320 for placing the fishing rope 2, and the notch 320 is close to the connecting position of the limiting ring 32 and the support 31. The notch 320 is arranged to facilitate the placement and removal of the fishing rope 2, and is convenient for assembly and disassembly. The position of the notch 320 is arranged to avoid the fishing rope 2 from being pulled out of the limiting ring 32 during work.

[0083] The feeding area 40 can be arranged on one side of the rice field, on both sides of the rice field, or even around the edge of the rice field, and the number and manner of arranging the feeding area 40 are not limited.

[0088] The movable ring 322 is rotatably installed on the fixed ring 321, and the movable ring 322 and the fixed ring 321 combine to form a limiting ring for limiting the fishing rope 2 in a ring direction.

[0089] Further, the movable ring 322 is rotatably connected with the end of the fixed ring 321 away from the support 31. The movable ring 322 is arranged to rotate along the horizontal plane, and the rotating end of the movable ring 322 is provided with a U-shaped bayonet 323. The bayonet 323 is provided with a snap spring 324. The snap spring 324 is in tension with the support 31.

[0090] It should be noted that in this embodiment, the limiting ring 32 is arranged as a fixed ring 321 fixedly connected with the support 31 and a movable ring 322 rotating relative to the fixed ring 321. When the fishing rope 2 needs to be inserted, the movable ring 322 is rotated and swung to make the movable ring 322 and the fixed ring 321 misaligned, and the notch 320 is exposed, so that the fishing rope 2 can be easily inserted. After the fishing rope 2 is inserted, the movable ring 322 is reset to splice with the fixed ring 321 to complete the limiting ring 32, which limits and supports the fishing rope 2.

[0091] Further, in order to facilitate the connection between the movable ring 322 and the support 31, a bayonet 323 is arranged at the position where the movable ring 322 is connected with the support, a snap spring 324 is arranged in the bayonet 323, when the support 31 is matched with the snap spring 324, the snap spring 324 is extruded in the ring direction of the support 31, so that the snap spring 324 is expanded, the support 31 is clamped, and the connection between the movable ring 322 and the support 31 is completed.

[0092] Embodiment 3:

[0093] As Figures 9 to 16 shown, the difference between the embodiment 3 and the embodiment 2 of the present application described with reference to the embodiment 2 is that:

By rotating the movable ring 322 around the fixed ring 321, the notch 320 on the fixed ring 321 can be opened, and after the fishing rope 2 is placed into the fixed ring 321, the movable ring 322 is rotated to combine the fixed ring 321 and the movable ring 322 to form the limiting ring 32 again, so as to limit the fishing rope 2.

[0096] Embodiment 4:

[0097] As Figures 17 to 20 shown, the difference between the embodiment 4 and the embodiment 3 of the present application described with reference to the embodiment 3 is that:

[0098] On the basis of the embodiment 3, a fixed half-circular pipe 3211 is added to the middle part of the fixed ring 321, an active half-circular pipe 3221 is added to one end of the movable ring 322, a handle 327 is added to the other end of the movable ring 322, and a floating seat 329 is arranged on the fixed half-circular pipe 3211 in a floating and lifting manner, wherein the lower end of the floating seat 329 on the fixed half-circular pipe 3211 penetrates through the fixed half-circular pipe 3211 and is arranged outside the fixed half-circular pipe 3211, the floating seat 329 and the fishing rope 2 are in contact with each other, and a plurality of rollers 328 are arranged on the floating seat 329 and the fishing rope 2, the floating seat 329 and the rollers 328 are hingedly arranged, and the roller 328 is a movable plate provided with a plurality of parallel rollers.

[0099] In operation, first, the rotating handle 327 is used to rotate the movable ring 322, so that the fixed semicircular tube 3211 coincides with the movable semicircular tube 3221, the diameter of the movable semicircular tube 3221 is larger than that of the fixed semicircular tube 3211, and the opening on the fixed semicircular tube 3211 is exposed. Then the fishing rope 2 is placed on the floating seat 329, and two groups of rollers 328 are arranged around the fishing rope 2 on the floating seat 329, forming a V-shaped space. After rotating the movable ring 322 again by the handle 327, the movable ring 322 is reset to form a complete limiting ring 32 with the fixed ring 321. At this time, the floating seat 329 is lowered, and the included angle between the two rollers 328 is reduced, so that the fishing rope 2 is positioned and covered, which is more conducive to subsequent pulling work.

[0100] Embodiment 5

[0101] As shown in Figures 21 to 24 Embodiment 5 of the present application is described with reference to Embodiments 1 to 4, which is a fishing method based on the above-mentioned rice frog unified fishing system, comprising the following steps:

[0102] Step one, laying the fishing net, laying the fishing net 1 on the feeding area 40 of the edge of the rice field 4, and connecting the end A of the fishing net 1 in the width direction with the protective net 5 on the edge of the rice field 4;

[0103] Step two, inserting the stand, inserting the stand 3 equidistantly along the length direction on the end B of the fishing net 1 in the width direction;

[0104] Step three, threading the fishing rope, threading the fishing rope 2 on the end B of the fishing net 1, and sequentially threading the limiting ring 32 on the stand 3 in order while the fishing rope 2 passes through the fishing net 1;

[0105] Step four, water storage, pouring water into the rice field 4 to raise the water level of the rice field 4 to the soil surface of the rice field 4, so that the rice frogs are transferred to the feeding area 40;

[0106] Step five, capture, pulling the fishing rope 2 to tighten it, lifting the end B on the fishing net 1 to the limiting ring 32 on the stand 3, and capturing the rice frogs on the feeding area 40 by the fishing net 1.
