Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of biological control of agricultural pests, and in particular relates to a breeding and seedling raising device for aphididae. Technical Background
[0002] The thick-spine aphid wasp is a parasitic wasp with a body length generally ranging from 0.8 to 2.6 mm. It can parasitize on aphids such as tobacco aphids, vegetable aphids, and cotton aphids. Its larvae absorb nutrients from the aphids' bodies, eventually leading to the death of the aphids, thereby achieving the purpose of controlling the number of aphids.
[0003] However, in the process of breeding the thick-spine aphid braconid, aphids are needed as hosts for reproduction, and aphids need to choose a plant to rely on for reproduction, so it is particularly important to breed this host plant. When cultivating parasitic plants, the density of parasitic plants in the local planting area on the seedling tray in the seedling box (the seedling box consists of a bottom plate, two pairs of side plates symmetrically arranged on the bottom plate and a top plate arranged on the side plate, thereby forming a cultivation cavity) should be considered. If the parasitic plants are planted too densely in the local planting area, the parasitic plants will compete with each other for light and nutrients in the soil, resulting in individual stunted development, and poor air circulation, which will reduce the light quality between the leaves and affect photosynthesis, thereby affecting the health and yield of the parasitic plants. At the same time, high-density planting is prone to cause various diseases, because the mutual shading between the leaves of the parasitic plants provides a better living environment for the pathogens, resulting in a lack of food for the parasitic aphids, and even causing the parasitic aphids to die from infection with pathogens.
[0004] At the same time, if the parasitic plants in the local planting area are too dense, the distribution of parasitic aphids will be too dense (parasitic aphids are densely distributed in areas with dense parasitic plants), which will lead to uneven distribution of parasitic aphids in the nursery box. In this case, in areas where parasitic aphids are densely distributed, the nutrients of the parasitic plants will be consumed too quickly. At this time, the parasitic aphids on the parasitic plants whose nutrients have been exhausted will move to another parasitic plant, but the activity of the parasitic aphids will gradually weaken over time (the reason for the weakening: as the thick-backed aphid wasp grows, the aphids slowly lose the ability to control their bodies, and the thick-backed aphid wasp will gradually eat away at the aphids' organs). At this time, some parasitic aphids will die on the parasitic plants without nutrients due to their weakened activity, thereby reducing the survival rate of the thick-backed aphid wasp.
[0005] Therefore, it is necessary to provide a seedling raising device capable of changing the distance between parasitic plants to avoid the concentrated distribution of parasitic aphids, so as to improve the survival rate of the thick-spine aphid wasp. Summary of the invention
[0006] The purpose of this application is to address the problem that the spacing between seedling trays in the seedling box in the prior art is unreasonable, resulting in unreasonable planting spacing of parasitic plants, causing parasitic aphids to gather and devour parasitic plants in the same area, or the same parasitic plant, so that parasitic aphids die on parasitic plants without nutrients due to reduced activity during the process of moving to another area or another parasitic plant.
[0007] To achieve the above objectives, this application provides the following technical solutions:
[0008] A seedling raising device for aphid wasps, comprising a seedling raising box and a plurality of seedling raising trays, wherein the seedling raising box is transparent, and two opposite side panels of the seedling raising box are provided with vertical adjustment grooves and a plurality of layers of horizontal limit grooves, and the adjustment grooves are connected with the limit grooves, and the two ends of the seedling raising trays are placed on the limit grooves, and the seedling raising trays can move along the limit grooves, and the adjustment grooves provide operating space for the seedling raising trays to move up and down.
[0009] Preferably, a plurality of limiting holes are provided on the bottom side of the limiting groove, and the limiting holes cooperate with the seedling raising tray to limit the length direction of the limiting groove.
[0010] Preferably, the limiting groove is provided with a brush strip.
[0011] Preferably, the adjustment groove is detachably provided with a sealing plate.
[0012] Preferably, a corrugated tube is detachably provided between adjacent seedling raising trays.
[0013] Preferably, the seedling tray includes a placement tray and a connecting rod, the placement tray is used to place parasitic plants, the connecting rod is respectively placed in the limiting holes on the two side panels, both ends of the connecting rod are clamped in the limiting holes and extend to the outside of the limiting holes.
[0014] Preferably, the seedling tray also includes a blocking plate, which is symmetrically arranged on the connecting rod and located outside the seedling box for blocking the limiting hole.
[0015] Beneficial effect: when the parasitic plants on a certain layer are planted too densely, the seedling tray is moved along the limiting groove to the adjusting groove, and then the seedling tray moved out of the adjusting groove is moved up or down to the limiting groove of another layer to change the number of seedling trays in the limiting groove of the same layer, and then change the spacing between the parasitic plants on this layer to adjust the density of the parasitic plants on this layer, so as to avoid the concentrated distribution of parasitic aphids due to the excessive density of local parasitic plants; at the same time, when the parasitic aphids on a certain seedling tray are distributed too densely, another seedling tray with fewer parasitic aphids can be moved near a certain seedling tray, so that some parasitic aphids are moved to another seedling tray, so as to avoid the situation where there is no nutrients available due to too many parasitic aphids, and avoid the situation where there are too many seedling trays on the same layer and the extra seedling trays need to be taken out, resulting in the parasitic aphids flying away.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation of the present patent. For ordinary technicians in the field, the specific meanings of the above terms can be understood according to the specific circumstances.
[0023] Please see Figures 1 to 4 A breeding and seedling raising device for aphid wasps includes a seedling raising box 10 and a plurality of seedling raising trays 20. The seedling raising box 10 is transparent. Two opposite side panels 110 of the seedling raising box 10 are provided with vertical adjusting grooves 120 and a plurality of horizontal limiting grooves 130, and the adjusting grooves 120 are connected with the limiting grooves 130. Both ends of the seedling raising trays 20 are placed on the limiting grooves 130, and the seedling raising trays 20 can move along the limiting grooves 130. The adjusting grooves 120 provide an operating space for the seedling raising trays 20 to move up and down.
[0024] Several layers of transverse limiting grooves 130 are arranged along the height direction of the seedling box 10, and the limiting grooves 130 are used to place the seedling tray 20, and the seedling tray 20 can be moved along the limiting grooves 130 to the vertically arranged adjusting grooves 120, and the height of the seedling tray 20 is adjusted in the adjusting grooves 120, and the removed seedling tray 20 is moved to another layer of limiting grooves 130.
[0025] Before placing parasitic aphids into the breeding and seedling raising device of the thick-ridged aphid braconid, it is necessary to adjust the spacing between the parasitic plants. At this time, if the parasitic plants in a certain layer are too dense, the staff will lift the seedling tray 20 from the outside of the seedling box 10, move the seedling tray 20 close to the adjustment groove 120 of this layer along the limiting groove 130 into the adjustment groove 120 (the width of the adjustment groove 120 is slightly larger than the width of the seedling tray 20), and place the seedling tray 20 just moved out into another layer of limiting grooves 130 in the adjustment groove 120, and then adjust the spacing between the seedling trays 20 in this layer. This avoids the situation where the local parasitic plants are too dense due to the unreasonable spacing between the seedling trays 20, and the parasitic plants cannot grow. At the same time, it also avoids the situation where the parasitic aphids are densely distributed due to the local parasitic plants being too dense.
[0026] At the same time, after the parasitic aphids are placed in the breeding and seedling raising device of the thick-ridged aphid braconid, when the parasitic aphids in the local area are too dense, in order to transfer some of the parasitic aphids, the parasitic plants with fewer parasitic aphids can be moved into this area, close to the parasitic plants with too dense parasitic aphids. At this time, due to the living habits of animals, some parasitic aphids will slowly move to the parasitic plants with fewer parasitic aphids, avoiding the situation where there are too many parasitic aphids on the parasitic plants, resulting in the parasitic aphids having no nutrients to obtain, and also avoiding the situation where when the parasitic plant has no nutrients to obtain, when the parasitic aphids move to another parasitic plant, due to the weakened activity ability, before they move to the next parasitic plant, some of the parasitic aphids die.
[0027] And when cultivating parasitic plants, the parasitic plants need to grow for a period of time in the breeding and seedling raising device of the thick-spine aphid bracone, and the height of the parasitic plants will become higher. For example, after the parasitic plants on the first layer (from bottom to top) seedling tray 20 grow for a period of time, their tops will contact the bottom of the second layer (from bottom to top) seedling tray 20. This situation will limit the growth of the parasitic plants on the first layer of seedling tray 20. Therefore, in order to better grow the parasitic plants on the first layer of seedling tray 20, the second layer of seedling tray 20 can be moved to the third layer (from bottom to top) limiting groove 130. At this time, there is no seedling tray 20 in the second layer of limiting groove 130, that is, there is no extra seedling tray 20 between the first layer of seedling tray 20 and the third layer of seedling tray 20, all of which are growth space for the parasitic plants on the first layer of seedling tray 20, ensuring that the parasitic plants on the first layer of seedling tray 20 can grow better.
[0028] In general, the cooperation between the limiting groove 130 and the adjusting groove 120 provides adjustment space for the seedling tray 20, so that the seedling tray 20 can switch positions arbitrarily between the multiple layers of limiting grooves 130 to adjust the number of seedling trays 20 in any layer, thereby achieving the adjustment of the density of parasitic plants in any layer.
[0029] At the same time, when setting the layer height of the limit groove 130, the height of different parasitic plants must be taken into consideration. For example, the height of wheat seedlings is about 6 to 30 cm, and the height of pumpkin seedlings is about 6-35 cm. When setting the limit groove 130, it is necessary to set the layer height of the limit groove 130 according to different parasitic plants, and then adjust the height of the seedling box 10.
[0030] It should be noted that: the opening height of the limiting groove 130 should be greater than the thickness of the seedling tray 20 to ensure that the seedling tray 20 can move in the limiting groove 130, and in order to observe the growth of the parasitic plants in the seedling box 10, the seedling box 10 can be set to be a transparent seedling box 10, and the transparent seedling box 10 can also provide sufficient light for the parasitic plants; and a fill light, a humidity detector and other components can be installed in the seedling box 10.
[0031] Furthermore, a plurality of limiting holes 131 are provided on the bottom side of the limiting groove 130 , and the limiting holes 131 cooperate with the seedling raising tray 20 to limit the length direction of the limiting groove 130 .
[0032] A plurality of limiting holes 131 are provided in the limiting groove 130. After the seedling tray 20 is moved to a suitable position, the seedling tray 20 is clamped in the limiting hole 131 to limit the lateral movement of the seedling tray 20, that is, after the seedling tray 20 is clamped in the limiting hole 131, it cannot move laterally in the limiting groove 130. When the seedling tray 20 needs to be moved, the seedling tray 20 is lifted up, taken out of the limiting hole 131, and then the position of the seedling tray 20 is adjusted.
[0033] In a preferred embodiment, the limiting groove 130 is provided with a brush strip.
[0034] The limiting groove 130 is a long through hole and is connected to the outside. At this time, some parasitic aphids will escape from the limiting groove 130. In order to prevent the parasitic aphids from escaping, a brush strip is provided on the limiting groove 130. The brush strip blocks the parasitic aphids in the breeding and seedling raising device of the thick-ridged aphid bracone. The brush strip is very soft and does not affect the movement of the seedling raising tray 20. When the brush strip is provided, it can be provided inside or outside the seedling raising box 10. At the same time, the thick-ridged aphid bracone breeding and seedling raising device must ensure air circulation when in use. The gaps between the bristles on the brush strip can be used to achieve the requirements of the thick-ridged aphid bracone breeding and seedling raising device for air circulation. When installing the brush strip, magnetic suction or sticking can be used. According to the use requirements, the brush strip can be installed inside or outside the seedling raising box 10.
[0035] In a preferred embodiment, the adjustment groove 120 is detachably provided with a sealing plate 121 .
[0036] In order to prevent parasitic aphids from escaping from the adjustment groove 120, when the seedling tray 20 does not need to be adjusted, the adjustment groove 120 is blocked using the sealing plate 121. When the seedling tray 20 needs to be adjusted, the sealing plate 121 can be removed from the seedling box 10. The sealing plate 121 can also be a door that can be opened and closed, a gauze, etc.
[0037] Specifically, a corrugated tube is detachably provided between adjacent seedling raising trays 20 .
[0038] In some special usage scenarios, it is only necessary to adjust the limiting grooves 130 on the same layer to adjust the spacing between the seedling trays 20. At this time, a corrugated tube is arranged between adjacent seedling trays 20. When adjusting the spacing between the seedling trays 20, it is only necessary to pull one of the seedling trays 20. Under the action of the corrugated tube, the other seedling trays 20 are driven to move, and the corrugated tube connects the separate seedling trays 20 together to facilitate the collection of the seedling trays 20.
[0039] In a specific embodiment, the seedling tray 20 includes a placement tray 210 and a connecting rod 220, the placement tray 210 is used to place parasitic plants, and the connecting rod 220 is respectively placed in the limiting holes 131 on the two side panels 110, and both ends of the connecting rod 220 are clamped in the limiting holes 131 and extend to the outside of the limiting holes 131.
[0040] The parasitic plants at both ends of the connecting rod are placed in the placement tray 210 for cultivation, and the seedling tray 20 is suspended in the seedling box 10 by using the connecting rod 220. When the seedling tray 20 needs to be moved, the staff only needs to grab the connecting rod 220 extending to the outside of the limiting hole 131 to move the seedling tray 20.
[0041] Specifically, a plurality of groups of placement holes are provided in the placement tray 210, and each group of the placement holes is kept parallel to each other, and is used to place the seedling cups for cultivating parasitic plants. The seedling cup is divided into a nutrient solution placement layer and a matrix placement layer. The matrix placement layer is arranged above the nutrient solution placement layer, and the nutrient solution placement layer and the matrix placement layer are separated by a partition. At the same time, a plurality of penetration holes are provided on the partition, and the roots of the parasitic plants can pass through the penetration holes to absorb the nutrient solution. In order to prevent the seedling cup from falling from the placement hole, a limiting clamp is fixedly provided on the outer wall of the seedling cup and at the top position, and the outer ring diameter of the limiting clamp is larger than the diameter of the placement hole, so that the seedling cup is clamped in the placement hole.
[0042] In a preferred embodiment, the seedling tray 20 further includes a blocking plate 230 , which is symmetrically arranged on the connecting rod 220 and located outside the seedling box 10 for blocking the limiting hole 131 .
[0043] The blocking plate 230 is fixedly arranged on the connecting rod 220, and the distance between the blocking plate 230 and the placing tray 210 is greater than the thickness of the side wall of the thick-ridged aphid bracone breeding and seedling raising device, which ensures that the seedling raising tray 20 can be stuck in the limiting through hole; at the same time, the setting of the blocking plate 230 also has the following beneficial effects: the blocking plate 230 can block the limiting hole 131 to prevent parasitic aphids from running out of the limiting hole 131, and the blocking plate 230 can limit the sliding position of the seedling raising tray 20, that is: when the seedling raising tray 20 is moved, if the connecting rod 220 at one end cannot overlap in the limiting hole 131, the seedling raising tray 20 will fall into the seedling raising box 10, and the seedling raising tray 20 will be tilted, and even the next layer of parasitic plants will be crushed.
[0044] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
