Description

Technical Field

[0001] This invention relates to the field of breeding greenhouse technology, and in particular to a greenhouse for breeding *Triplophysa fasciata* and its breeding method. Background Technology

[0002] The forked-horned bug (Triplophysa fasciata) is an important predatory natural enemy of agricultural and forestry crop pests. It preys on various Lepidoptera and Coleoptera pests, particularly the larvae of diamondback moth, beet armyworm, cotton bollworm, and inchworm. The forked-horned bug is mainly distributed in many southern provinces of my country, and it is frequently seen in fields preying on the larvae of various Lepidoptera pests on vegetables, fruits, tea, and other crops, serving as a biological control force against Lepidoptera. However, because the forked-horned bug is a relatively new species and research on it is limited, it is mostly captured in the wild. The limited artificial breeding involves feeding mealworms in insect rearing boxes, which is small-scale and requires frequent replenishment of mealworms. Furthermore, since the forked-horned bug only feeds on the body fluids of insects, it leaves a large number of mealworm exoskeletons in the rearing boxes, necessitating frequent cleaning. Summary of the Invention

[0003] The purpose of this invention is to provide a greenhouse for the cultivation of Forked-horned bugs and a cultivation method thereof, which is used for the large-scale cultivation of Forked-horned bugs. The cultivation method is simple, the cultivation cost is low, and the cultivated Forked-horned bugs are of better quality.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A greenhouse for cultivating Asparagus crickets includes a ring-shaped greenhouse. The ring-shaped greenhouse is divided into multiple cultivation compartments for growing Asparagus by multiple vertical partitions arranged in a circle. Each cultivation compartment has an entrance door on the outside of the ring-shaped greenhouse, and each entrance door is hinged with a sealing door.

[0006] Each vertical partition layer includes multiple vertically arranged support columns, multiple roll blinds placed between each pair of support columns, and a storage strip horizontally arranged at the top of the support columns with an open bottom. A roller is rotatably connected to each pair of support columns within the storage strip. Each roll blind is wound around a random roller. Gears are provided at both ends of each roller. Each support column has an inwardly opening U-shaped sliding groove with an upward opening on the side closest to the corresponding roll blind. A gear belt is movably arranged within each U-shaped sliding groove. The upper end of each gear belt meshes with the corresponding gear. A connecting strip is connected to the bottom edge of each roll blind. Both ends of each connecting strip are connected to one side of the corresponding gear belt.

[0007] Each breeding cell contains multiple oviposition boxes. Each oviposition box has multiple entry and exit holes at both the front and rear ends. The size of the entry and exit holes is sufficient to allow the forked-horned bug to enter but not the adult fall armyworm. The upper end of the oviposition box has a strip-shaped insertion hole running along its length. An oviposition plate that can be detachably connected to the oviposition box and inserted through the strip-shaped insertion hole is provided inside the oviposition box. An oviposition-proof mesh layer is provided on the inner side of the oviposition box.

[0008] A further feature of the present invention is that multiple supplemental lights are installed on the top of each breeding cell inside the annular greenhouse.

[0009] A further feature of the present invention is that multiple infrared heating lamps are installed on the top of each breeding cell inside the annular greenhouse.

[0010] A further feature of the present invention is that ventilation fans are installed on both the front and back sides of each breeding cell inside the annular greenhouse, and each ventilation fan is provided with an insect-proof net on one side inside the annular greenhouse.

[0011] A further feature of the present invention is that asparagus is planted in rows in each cultivation cell, and the spawning box is located around the asparagus planting rows and around the vertical partition layer.

[0012] A further feature of the present invention is that each egg-laying plate is provided with a handle at its upper end.

[0013] A further feature of the present invention is that asparagus is planted in rows in each breeding cell, and multiple fall armyworm oviposition platforms are provided in each breeding cell around the asparagus planting rows and around the vertical dividing layer. The upper end of each fall armyworm oviposition platform is covered with rough kraft paper.

[0014] A further feature of the present invention is that a handle is provided on one side of the middle portion of each connecting strip.

[0015] This invention also discloses a method for greenhouse cultivation of the forked-horned bug, wherein the forked-horned bug is cultivated in a greenhouse, and the specific steps are as follows:

[0016] S1. Plant asparagus in each breeding cell inside the circular greenhouse and manage the water and fertilizer for the asparagus.

[0017] S2. After the asparagus leaves have grown lush, introduce fall armyworm into one of the breeding cells.

[0018] S3. When there are fall armyworm larvae in the breeding cells of fall armyworm, introduce forked bugs. When laying eggs, forked bugs will enter the dark and hidden oviposition boxes to lay eggs. Regularly check and collect the oviposition plates in the oviposition boxes.

[0019] S4. When the asparagus leaves in the breeding cell are about to be eaten up by the fall armyworm larvae, open the next adjacent breeding cell. The fall armyworm adults will migrate to the next breeding cell under the attraction of food. The forked bug will also migrate to the next breeding cell along with the fall armyworm. Alternatively, light can be used in the next breeding cell to attract the fall armyworm and forked bug to migrate.

[0020] S5. Repeat the operation of S4 to allow the fall armyworm and the forked bug to circulate and migrate within the breeding cells of the circular greenhouse.

[0021] More preferably, the temperature inside the annular greenhouse is controlled at 25-30℃, the humidity at 70±10%, and the daytime light intensity at 40000 lux.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Firstly, this invention utilizes a greenhouse for the cyclical breeding of the forked-horned bug, which facilitates the mass breeding of the bug. Asparagus is planted inside the greenhouse, and fall armyworms eat the asparagus, while the forked-horned bugs eat the fall armyworms. This cyclical food chain is used for the breeding of the forked-horned bugs. The breeding is carried out in a cyclical manner within the breeding cells. After the asparagus is consumed, it is transferred to the next breeding cell. When it returns to the original breeding cell, the asparagus has grown lush leaves again. Since asparagus is a perennial plant, it can quickly sprout and grow leaves after being consumed, eliminating the need for replanting and frequent replenishment of food sources for the forked-horned bugs, thus simplifying the breeding process.

[0024] Secondly, because asparagus is rich in nutrients, the fall armyworm that grows up eating asparagus leaves has even higher nutritional value, and the forked horned bug that grows up eating the fall armyworm has even higher quality.

[0025] Thirdly, the circular greenhouse of the present invention has multiple breeding compartments, which facilitates the cyclic breeding of the forked bug within the greenhouse. Furthermore, the design of the vertical partition layer makes it easy to open and close, which helps the fall armyworm and the forked bug migrate. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example, refer to Figure 1-5 A greenhouse for cultivating *Asparagus spp.* includes a ring-shaped greenhouse. The ring-shaped greenhouse is divided into six vertically spaced sections 1 arranged in a circular pattern, forming six cultivation compartments 2 for asparagus cultivation. Each cultivation compartment 2 has an entrance / exit 21 on its outer side, and each entrance / exit 21 is hinged with a sealing door 22. Four supplemental lighting lamps 31 are installed at the top of each cultivation compartment 2 inside the ring-shaped greenhouse to provide supplemental lighting when light is insufficient, ensuring adequate light for the asparagus. Two infrared heating lamps 32 are also installed at the top of each cultivation compartment 2 inside the ring-shaped greenhouse to supplement warmth when temperatures are too low in winter. Ventilation fans 4 are installed on both the front and back sides of each cultivation compartment 2 inside the ring-shaped greenhouse. Each ventilation fan 4 has an insect-proof net 41 installed on one side inside the ring-shaped greenhouse. The ventilation fans 4 are used for ventilation and heat dissipation, and the insect-proof nets 41 prevent *Asparagus spp.* and fall armyworm from entering the ventilation fans 4.

[0034] Each vertical partition layer 1 includes five vertically arranged support columns 11, four roller blinds 12 arranged between each pair of support columns 11, and a horizontally arranged storage strip 13 with an open bottom end at the top of the support column 11. A roller 14 is rotatably connected within the storage strip 13 between each pair of support columns 11. Each roller blind 12 is wound around a random roller 14. A gear 15 is provided at both ends of each roller 14. Each support column 11 has an inwardly opening U-shaped sliding groove 16 on the side closest to the corresponding roller blind 12. A movable mechanism is movably arranged within each U-shaped sliding groove 16. The gear belt 17 has its upper end meshing with the corresponding gear 15. Each roller blind 12 has a connecting strip 18 connected to its lower side. Both ends of each connecting strip 18 are connected to one side of the corresponding gear belt 17. Each connecting strip 18 has a handle 19 on one side of its middle section. By pulling the connecting strip 18 up and down through the handle 19, the gear belt 17 can be driven to rotate in the U-shaped sliding groove 16. The gear belt 17 drives the gear 15 to rotate, causing the roller 14 to wind or unwind the roller blind 12, thus realizing the rapid opening and closing of the vertical partition layer 1.

[0035] In each breeding cell 2, asparagus is planted in rows. In each breeding cell 2, multiple oviposition boxes 5 are set around the asparagus planting rows and around the vertical partition layer 1. The forked-horned bug needs a hidden and quiet oviposition space to lay eggs. The oviposition boxes 5 can provide oviposition space for the forked-horned bug and can attract the forked-horned bug to lay eggs. Each oviposition box 5 has multiple entrance and exit holes 51 at both the front and rear ends. The size of the entrance and exit holes 51 is sufficient to allow the forked-horned bug to enter but not to allow the fall armyworm adult to enter. The fall armyworm adult is much larger than the forked-horned bug, which can prevent the fall armyworm from entering to lay eggs. The top of the oviposition box 5 has a downward-facing strip-shaped insertion hole 52 running along its length. An oviposition plate 6, inserted through the strip-shaped insertion hole 52, is detachably connected inside the oviposition box 5. The forked-horned bug can lay its eggs on the oviposition plate 6. Each oviposition plate 6 has a handle 61 at its top. An anti-oviposition mesh layer 53 is installed inside the oviposition box 5 to prevent the forked-horned bug from laying eggs on the inner wall of the oviposition box 5. Each breeding cell 2 has multiple fall armyworm oviposition platforms 7 located around the asparagus planting rows and the vertical dividing layer 1. Each fall armyworm oviposition platform 7 has a rough kraft paper 71 at its top, as fall armyworms prefer to lay their eggs on the rough kraft paper 71, preventing the fall armyworms from laying eggs on the inner wall of the greenhouse and making cleaning difficult.

[0036] A method for greenhouse cultivation of the forked-horn bug (Berberis thunbergii) involves using a ring-shaped greenhouse. During cultivation, the temperature inside the greenhouse is controlled at 25-30℃, humidity at 70±10%, and daytime light intensity at 40,000 lux. The specific steps are as follows:

[0037] S1. Plant asparagus in each breeding cell 2 inside the circular greenhouse and manage the water and fertilizer for the asparagus.

[0038] S2. After the asparagus leaves have grown lush, introduce fall armyworm into one of the breeding cells 2.

[0039] S3. When there are fall armyworm larvae in the breeding grid 2 of the fall armyworm, introduce the forked bug. When the forked bug lays eggs, it enters the dark and hidden oviposition box 5 to lay eggs. Regularly check and collect the oviposition plates 6 in the oviposition box 5.

[0040] S4. When the asparagus leaves in breeding cell 2 are about to be eaten up by the fall armyworm larvae, open the next adjacent breeding cell 2. The adult fall armyworms will migrate to the next breeding cell 2 under the attraction of food. The forked bug will also migrate to the next breeding cell 2 along with the fall armyworms. Alternatively, light can be used in the next breeding cell 2 to attract the fall armyworms and forked bugs to migrate.

[0041] S5. Repeat the operation of S4 to allow the fall armyworm and the forked bug to circulate and migrate within the breeding grid 2 of the circular greenhouse.

[0042] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
