Description

Technical Field

[0001] This utility model relates to the field of strawberry tissue culture technology, and in particular to a rooting induction device for strawberry tissue culture. Background Technology

[0002] Strawberry hydroponic rooting induction is a complex process involving physiological and biochemical changes in plants. Under high humidity conditions, some terrestrial plants, such as strawberries, will regrow new adventitious roots with well-developed parenchyma tissues from injured areas or cuts to compensate for growth and maintain balance after root removal. When these adventitious roots first enter the water, environmental (oxygen) stress induces physiological and biochemical changes within the plant, leading to the formation of large amounts of cellulase. This process promotes the decomposition of cell walls in parenchyma cells, forming aerenchyma bundles or air-storage cavities, also known as lysophylloid tissue, which ultimately forms aquatic roots. Under hydroponic conditions, strawberry roots exhibit significant structural changes. The cortical cell layer of hydroponic roots has more layers, is loosely arranged, and has larger cell volume. The entire cortex occupies a larger proportion of the root cross-section, while the vascular cylinder occupies a relatively smaller proportion. The xylem and phloem are degenerate and their structure is not prominent. This process requires appropriate nutrient solution, oxygenation time, and treatment with plant growth regulators such as 3-IBA (indolebutyric acid) to screen for the optimal conditions for strawberry hydroponic root induction. These techniques can effectively promote rooting and growth of strawberries in a hydroponic environment.

[0003] Currently, strawberry hydroponic rooting can be achieved through, for example, a rooting device for hydroponic strawberries described in application number CN201820960221.7. The key technical features include a box body with a support plate slidably connected to its inner wall. Multiple placement holes are provided on the top wall of the support plate, into which culture pots are placed. Multiple limiting tubes are installed on the bottom wall of the support plate, with the bottom of the culture pots placed within the limiting tubes. A water inlet pipe is located inside the box body. An aerator is installed on the outside of the box body, with multiple air supply pipes installed on the output end of the aerator. The end of each air supply pipe away from the aerator penetrates the side wall of the box body and is fitted with an air stone. A fixing rod is installed on the inner side wall of the box body near the bottom, with each air stone mounted on the side wall of the fixing rod. A drain pipe is installed at the bottom of the box body.

[0004] The above-mentioned technical solution involves placing the strawberry plants to be hydroponically grown into a culture pot, allowing the strawberry plants to come into contact with the culture solution and thus develop roots. However, because there are small holes on the side of the culture pot, the roots of the strawberry plants may pass through the small holes during the growth process, causing the roots of the strawberry plants to become entangled in the culture pot. This makes it difficult to remove the strawberry plants from the culture pot after hydroponics is completed, and if necessary, it may cause a large number of strawberry plant roots to be torn off.

[0005] Therefore, a rooting induction device for strawberry tissue culture is proposed to solve or alleviate the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rooting induction device for strawberry tissue culture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rooting induction device for strawberry tissue culture includes a transparent cover with an open top and a light-transmitting plate that can close the top of the transparent cover. The transparent cover is filled with a culture medium. The top surface of the light-transmitting plate has several downwardly recessed grooves. The bottom surface of the grooves has several through-grooves that penetrate the light-transmitting plate. A lower permanent magnet ring is fixedly connected to the bottom of the grooves. An upper permanent magnet ring is detachably connected to the lower permanent magnet ring. The device also includes a biodegradable film bag. The biodegradable film bag includes a limiting piece that is clamped between the upper and lower permanent magnet rings and a planting receiving part that is integrally formed with the limiting piece and extends below the surface of the culture medium. The bottom of the planting receiving part has a perforation, and the lower outer ring of the planting receiving part has several water-permeable holes.

[0009] Preferably, the biodegradable film bag is made of PLA film or PCL film.

[0010] Preferably, the top surface of the light-transmitting plate has several through holes, and the bottom surface of the light-transmitting plate is fixedly connected with several support tubes that are coaxially arranged and connected with the through holes. The outer ring of the support tubes has several vent holes that are connected with the interior and located below the culture medium. The lower end of the support tubes is in contact with the bottom surface of the inner side of the light-transmitting cover.

[0011] Preferably, it also includes an air source, which aerates the inside of each support pipe.

[0012] Preferably, the air source is an air pump, and the top surface of the light-transmitting plate is fixedly connected to a connecting pipe network that communicates with a plurality of through holes. The connecting pipe network is connected to a main pipe, and the main pipe is detachably connected to the air outlet of the air pump and can be connected in a continuous manner.

[0013] Preferably, a connecting flange is fixedly connected to the outer ring of the end of the main pipe away from the connecting pipe network. The connecting flange is fitted to the flange of the air pump, and the connecting flange and the flange of the air pump can be detachably connected by a bolt and nut structure.

[0014] Preferably, the system also includes a frame, the light-transmitting cover is fixedly connected to the frame, a connecting frame is fixedly connected to one side of the frame, and the air pump is fixedly connected to the connecting frame.

[0015] This utility model has the following beneficial effects:

[0016] When using this invention, first place the strawberry to be rooted into a biodegradable film bag, ensuring that the bottom of the strawberry is in contact with the planting support. Use the weight of the strawberry itself to keep the planting support in a taut state. Then, immerse part of the film bag into a light-transmitting cover containing nutrient solution, allowing the nutrient solution to flow into the film bag through the water-permeable holes and the perforations at the bottom, nourishing the strawberry and promoting its rooting.

[0017] To secure the film bag, the upper end of the bag is unfolded to form a limiting piece, which is then placed in a recess. Subsequently, the upper permanent magnet ring is placed into the recess, so that it attracts the lower permanent magnet ring, thereby clamping the limiting piece and fixing the film bag.

[0018] During daily cultivation, in order to avoid strawberry hypoxia and sedimentation of the culture solution, the air pump will work continuously to deliver air into the culture solution through a series of pipes and vents to achieve aeration. This process not only prevents the culture solution from settling, but also provides the strawberry with the necessary oxygen to maintain its growth vitality.

[0019] The light-transmitting cover, light-transmitting plate, and film bag are all made of transparent materials to ensure that the light required for strawberry rooting is not affected, creating an ideal rooting environment.

[0020] After the rooting culture is completed, the user only needs to manually remove the upper permanent magnet ring, take out the film bag, and cut, tear or leave the planting receiving part as needed. Then, the rooted strawberry plant is transferred to the soil for cultivation. This method reduces damage to the strawberry roots and significantly improves the survival rate of the plant after soil cultivation. Attached Figure Description

[0031] A rooting induction device for strawberry tissue culture, such as Figure 1 and Figure 2As shown, the device includes a frame 1, a transparent cover with an open top, and a light-transmitting plate 3 that can close the top of the transparent cover. The light-transmitting cover 2 is fixedly connected inside the frame 1. The transparent cover is filled with culture medium. The top surface of the light-transmitting plate 3 has several downwardly recessed grooves. The bottom surface of the grooves has several through grooves that penetrate the light-transmitting plate 3. A lower permanent magnet ring is fixedly connected to the bottom of the grooves. The lower permanent magnet ring is detachably connected to an upper permanent magnet ring 5. The device also includes a biodegradable film bag. Specifically, the biodegradable film bag is made of PLA film or PCL film. The biodegradable film bag includes a limiting piece 4 that is sandwiched between the upper permanent magnet ring 5 and the lower permanent magnet ring, and a planting receiving part 11 that is integrally formed with the limiting piece 4 and extends to the bottom of the culture medium. The bottom of the planting receiving part 11 has a perforation, and the lower outer ring of the planting receiving part 11 has several water-permeable holes 12.

[0032] The top surface of the light-transmitting plate 3 has several through holes. The bottom surface of the light-transmitting plate 3 is fixedly connected to several support tubes 13 that are coaxially arranged and connected to the through holes. The outer ring of the support tubes 13 has several vent holes 14 that are connected to the inside and located below the culture medium. The lower end of the support tubes 13 is in contact with the bottom surface of the light-transmitting cover 2. It also includes an air source, which aerates each support tube 13. The air source is an air pump 9. A connecting frame 8 is fixedly connected to one side of the frame 1. The air pump 9 is fixedly connected to the connecting frame 8. The top surface of the light-transmitting plate 3 is fixedly connected to a connecting pipe network 6 that is connected to several through holes. The connecting pipe network 6 is connected to a main pipe 7. The main pipe 7 is detachably connected to the air outlet of the air pump 9 and can be connected. Specifically, the outer ring of the main pipe 7 away from the connecting pipe network 6 is fixedly connected to a connecting flange 10. The connecting flange 10 is fitted with the flange of the air pump 9, and the connecting flange 10 and the flange of the air pump 9 can be detachably connected by a bolt and nut structure.

[0033] In practical use, the strawberries that need to be rooted and induced are first placed into the biodegradable film bag, and the strawberries are allowed to fall to the bottom of the planting receiving part 11. The weight of the strawberries keeps the planting receiving part 11 taut and partially submerged in the culture solution of the light-transmitting cover 2. The culture solution can enter the biodegradable film bag through the water-permeable hole 12 and the bottom perforation, so that the strawberries needing to be rooted and induced are nourished by the culture solution. Then, in order to fix it, the upper end of the biodegradable film bag is spread out in the sink, forming a limiting piece 4. The upper permanent magnet ring 5 is then placed in the sink, so that the upper permanent magnet ring 5 can be attracted together with the lower permanent magnet ring, thereby clamping the limiting piece 4 and fixing the biodegradable film bag.

[0034] In the daily rooting culture process, in order to avoid the strawberry that needs to be rooted and induced to develop oxygen deficiency, and to ensure that the culture solution does not settle in the light-transmitting cover 2, the air pump 9 can be put into operation. This allows air to be blown into the culture solution through the main pipe 7, connecting pipe network 6, through hole, support pipe 13, and vent hole 14 to aerate the culture solution. This keeps the culture solution in a bubbling and flowing state, making it less prone to settling, and also provides the necessary oxygen for the strawberry that needs to be rooted and induced to develop oxygen.

[0035] The light-transmitting cover 2, the light-transmitting plate 3, and the biodegradable film bag are all transparent, so the light required for the strawberry to undergo rooting induction culture will not be blocked, and a more suitable rooting culture environment can be provided for the strawberry to undergo rooting induction culture.

[0036] Once the rooting culture is complete, people only need to manually remove the upper permanent magnet ring 5, take out the biodegradable film bag, and then cut, tear, or leave the planting receiving part 11 of the biodegradable film bag untreated. The rooted strawberry plant can then be planted in soil. In this way, it is less likely to damage the roots and stems of the strawberry plant, greatly improving its survival rate after soil cultivation.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
