Description

Technical Field

[0001] This invention relates to the field of potato seedling cultivation technology, and in particular to a constant temperature and humidity potato seedling rapid propagation equipment and its cultivation method. Background Technology

[0002] Potato seedling cultivation refers to the process of cultivating potato seed tubers or seedlings into robust, uniform seedlings of the appropriate age to provide high-quality seedlings for subsequent transplanting or breeding. It requires the use of constant temperature and humidity cultivation equipment to avoid soil-borne diseases and solve problems such as poor root development, in order to cultivate uniform and robust seedlings.

[0003] For example, Chinese patent CN222284224U discloses a soilless potato seedling cultivation device. It includes a water tank with an open top; a box body with a hollow, inverted isosceles trapezoidal cross-section, its bottom positioned above the water tank; a planting trough located on top of the box body; and a sprayer located inside the box body.

[0004] The aforementioned patent provides a relatively spacious growing space that facilitates the diffusion of nutrient solution mist, thus promoting absorption by potato seedling roots. However, existing cultivation equipment still has some shortcomings that urgently need improvement. In mainstream cultivation methods such as potato aeroponics and hydroponics, potato roots tend to intertwine and clump together during growth, forming a dense root cluster structure. The mist sprayed from the nozzles of existing equipment cannot effectively penetrate this dense root cluster, resulting in obvious dead zones for water and fertilizer spraying. Consequently, some roots within the root cluster remain dry due to lack of water and fertilizer access, while others rot and deteriorate due to the accumulation of water and fertilizer that cannot evaporate in time. This significantly reduces the survival rate of potato seedlings and also affects the quality of breeding and cultivation, reducing the efficiency of rapid propagation of potato seedlings. Summary of the Invention

[0005] The purpose of this invention is to provide a constant temperature and humidity potato seedling rapid propagation equipment and its cultivation method to solve the problems mentioned in the background art.

The guide blocks are fixedly connected to both sides of the linkage block.

[0008] Furthermore, the root thinning mechanism includes a reciprocating assembly, which is located on both sides inside the cultivation cylinder. One side of the mounting base is slidably connected to an assembly ring via the reciprocating assembly and is located above the linkage empty rod. Flexible comb teeth are installed on the periphery of the assembly ring, and an assembly block is fixedly connected to the periphery of the assembly ring. The flexible comb teeth are rotatably connected to the assembly block via a shaft. The reciprocating assembly allows the flexible comb teeth to oscillate slightly, facilitating root thinning.

[0009] Furthermore, the reciprocating assembly includes an air pump, which is fixedly connected to both sides inside the cultivation cylinder. A spring air tube is fixedly connected to the output end of the air pump. One side of the spring air tube is fixedly connected to one side of the linkage block. One side of the linkage rod extends into the linkage block and is fixedly connected to the air guide tube. An air inlet pipe is fixedly connected to the input end of the air pump. A piston is slidably connected to one side of the linkage rod through the assembly seat. A push rod is fixedly connected to the top of the piston. A push block is fixedly connected to one side of the push rod. One side of the push block is fixedly connected to one side of the assembly ring.

[0010] Furthermore, the liquid supply mechanism includes an annular spray head, which is embedded and connected to the upper side of the assembly ring. Flexible hoses are fixedly connected to both sides of the bottom end of the annular spray head, and a ring pipe is fixedly connected between the two hoses. A fixed pipe is fixedly connected to the bottom end of each hose.

[0011] Furthermore, the installation component includes a mounting bracket, which is fixedly connected to both sides of the upper outer portion of the cultivation cylinder. The mounting bracket has a sliding groove inside, and an elastic locking block is fixedly connected to one side of the sliding groove. A slider is slidably connected inside the sliding groove, and locking holes are provided on both sides of the slider. The elastic locking block engages with the locking holes.

[0012] A cultivation method for a constant temperature and humidity potato seedling rapid propagation cultivation device includes the following steps: S1. Turn on the power to the incubator and monitor the temperature and humidity in real time to maintain stable temperature and humidity inside the chamber. Inject the prepared seedling nutrient solution into the water tank of the liquid supply mechanism and close the solenoid valve. S2. Select the appropriate positioning ring according to the size of the culture sample, and fix it to the top of the cultivation tube through the installation component. Check the honeycomb mesh inside the cultivation tube to ensure that it is firmly fixed and undamaged. S3. Select healthy, disease-free potato seedlings, pass their roots through the holes of the positioning rings and into the inner cavity of the cultivation tube, fix the main body of the seedlings by limiting the positioning rings, and press the contact parts to ensure that the seedlings do not shake. S4. Close the incubator lid, turn on the plant lights and set the illumination time and brightness. Monitor the temperature and humidity in real time. If the temperature and humidity deviate from the set value, adjust them in time through the controller to maintain a constant temperature and humidity environment. S5. When the seedling roots grow to a certain length, the power mechanism is activated to drive the assembly seat, rubber top block and elastic top plate to rise, and to initially disperse the tangled root ball; at the same time, the root-clearing mechanism air pump is activated, which drives the flexible comb teeth to move upward and swings slightly, so that they can penetrate and further comb the roots to spread out radially. S6. While dredging the root system, start the water pump of the nutrient solution supply mechanism to deliver the nutrient solution to the ring spray head through the three-way pipe, ring pipe and hose. After atomization, it is evenly sprayed onto the surface of the seedling root system to ensure that the nutrient solution is covered without dead corners. S7. Regularly open the box lid to check the growth status of the seedlings and the condition of the root system, promptly clean up rotten roots, and check the operation status of the power mechanism, root thinning mechanism, and liquid supply mechanism. S8. When the seedlings grow to the appropriate age and meet the requirements for transplanting or breeding, stop all equipment operation, open the box cover, remove the positioning ring, and gently lift the seedlings to complete the harvest. After harvesting, clean the cultivation cylinder, positioning ring, honeycomb mesh and other parts to prepare for the next batch of cultivation.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by setting up a cultivation cylinder and fixing a honeycomb mesh inside, the potato root system can be initially separated and limited, preventing the roots from becoming entangled in the early stages of growth and allowing the roots to begin to unfold and grow. Positioning rings for fixing potato seedlings of different sizes are detachably installed at the top of the cultivation cylinder to position the potato seedlings and ensure stable root growth. A power mechanism inside the cultivation cylinder moves the assembly seat upwards, allowing the conical rubber top block to smoothly insert into the growing root cluster. Combined with the elastic action of multiple elastic top plates, this initially disperses and combs through the tangled root cluster, breaking up the dense root structure, and simultaneously utilizing… The root-sparser mechanism at the mounting base further organizes the initially dispersed root system, allowing it to grow radially. This prevents roots from tangling and restricting their growth. At this point, the hydration system sprays water, allowing the mist to penetrate the spread-out roots and provide even nutrition and moisture to all areas of the potato root system. This effectively prevents some roots from drying out due to lack of water and fertilizer, and others from rotting due to accumulated water and fertilizer. This significantly improves the survival rate of potato seedlings, ensures breeding quality, and enhances the efficiency of rapid potato propagation. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-10In this embodiment of the invention, a constant temperature and humidity potato seedling rapid propagation device includes a cultivation box 1, with a main controller installed on one side of the cultivation box 1. A box cover 2 is hinged to one side of the cultivation box 1. Plant lights 201 are fixedly connected to both sides of the inside of the box cover 2. A temperature sensor 202 is fixedly connected to the box cover 2 on one side of the plant lights 201. A cultivation cylinder 3 is fixedly connected to the middle of the inside of the cultivation box 1. The cultivation cylinder 3 is made of transparent material. A humidity sensor 301 is fixedly connected to one side of the cultivation cylinder 3. The cultivation box 1 is a sealed and heat-insulating structure, which can work with the temperature sensor 202 on the box cover 2 and the humidity sensor 301 on the side of the cultivation cylinder 3 to monitor the temperature and humidity parameters in the cultivation chamber in real time, providing stable conditions for the growth of potato seedlings. A honeycomb structure is fixedly connected to the top opening of the cultivation cylinder 3. Net 302, the top of the cultivation cylinder 3 is provided with a positioning ring 12, and a mounting component 13 is provided on one side of the positioning ring 12. The two sides of the inside of the cultivation cylinder 3 are fixedly connected with a fixing frame 4. A power mechanism 5 is provided on one side of the fixing frame 4. An assembly seat 6 is movably connected to the inside of the cultivation cylinder 3 through the power mechanism 5. A rubber top block 7 is fixedly connected to the top of the assembly seat 6. The rubber top block 7 has a conical structure. An elastic top piece 8 is fixedly connected to the middle periphery of the rubber top block 7, and there are multiple elastic top pieces 8. A root thinning mechanism 9 is provided on one side of the assembly seat 6. A liquid supply mechanism 10 is provided on the assembly seat 6 on one side of the root thinning mechanism 9. The purpose of the spraying operation of the liquid supply mechanism 10 is to supply nutrient solution to the roots of potato seedlings. At the same time, the atomized nutrient solution droplets can help maintain the humidity in the cultivation chamber, without the need for an additional humidifier.

[0018] Please see Figure 5-9The power mechanism 5 includes a motor 51, which is fixedly connected to one side of the inside of the cultivation box 1. A drive rod 52 is fixedly connected to the output end of the motor 51. The drive rod 52 is rotatably connected to the cultivation cylinder 3. Worms 53 are fixedly connected to both sides of the drive rod 52. A worm wheel 54 is meshed with one side of the worm 53. The worm wheel 54 is fixedly connected to the lower side of the lead screw 55 passing through the fixed frame 4. A linkage block 58 is threaded onto the outer surface of the lead screw 55. The linkage block 58 is slidably connected inside the fixed frame 4. A linkage empty rod 59 is fixedly connected between the linkage block 58 and the mounting base 6. Guide grooves 57 are provided on both sides of the inside of the fixed frame 4. The groove 57 has a guide block 56 that is slidably connected inside, and the guide block 56 is fixedly connected to both sides of the linkage block 58. Through the structure of motor 51, drive rod 52, worm gear 53, worm wheel 54, lead screw 55, linkage block 58, and linkage empty rod 59, the assembly seat 6 can be raised and lowered, which in turn drives the rubber top block 7, elastic top plate 8, root thinning mechanism 9, and liquid supply mechanism 10 to rise and fall synchronously. This ensures that precise guidance and liquid supply operations can be carried out for roots at different growth stages, effectively solving the problem of root tangling, avoiding dead corners in water and fertilizer spraying, ensuring that the roots can absorb water and fertilizer evenly, reducing the occurrence of root rot and drought, improving the survival rate and cultivation quality of potato seedlings, and helping the rapid propagation of seedlings to proceed smoothly.

[0019] Please see Figure 9-10 The root thinning mechanism 9 includes a reciprocating assembly 95, which is located on both sides inside the cultivation cylinder 3. One side of the mounting base 6 is slidably connected to an assembly ring 91 via the reciprocating assembly 95, and is positioned above the linkage rod 59. Flexible comb teeth 92 are mounted on the periphery of the assembly ring 91, and an assembly block 93 is fixedly connected to the periphery of the assembly ring 91. The flexible comb teeth 92 are rotatably connected to the assembly block 93 via a shaft 94. The reciprocating assembly 95 allows the flexible comb teeth 92 to oscillate slightly, facilitating root thinning. The reciprocating assembly 95 and the mounting base 6 are connected to the assembly ring 91. The structure, including the matching ring 91, flexible comb teeth 92, and assembly block 93, can gently and comprehensively comb through the tangled potato root system. The flexible comb teeth 92 can penetrate deep into the root cluster, gradually separating the intertwined roots and allowing them to spread out radially. This breaks up the dense root structure and provides favorable conditions for the mist penetration of the liquid supply mechanism 10, preventing some roots from drying out due to lack of water and fertilizer, and preventing some roots from rotting due to water and fertilizer accumulation. At the same time, the flexible structure can avoid damaging the root system, ensuring normal root growth and development, and further improving seedling quality and rapid propagation efficiency.

[0020] Please see Figure 6 and Figure 9The reciprocating assembly 95 includes an air pump 951, which is fixedly connected to both sides inside the cultivation cylinder 3. A spring air tube 952 is fixedly connected to the output end of the air pump 951. One side of the spring air tube 952 is fixedly connected to one side of the linkage block 58. One side of the linkage rod 59 extends into the linkage block 58 and is fixedly connected to the air guide tube. An air inlet pipe 953 is fixedly connected to the input end of the air pump 951. A piston 954 is slidably connected to one side of the linkage rod 59 through the mounting base 6. A push rod 955 is fixedly connected to the top of the piston 954. A pushing block 956 is fixedly connected to one side of the pushing rod 955, and one side of the pushing block 956 is fixedly connected to one side of the assembly ring 91. Through the structure of air pump 951, spring air pipe 952, air guide pipe, piston 954, pushing rod 955 and pushing block 956, the assembly ring 91 can be stably driven to move, thereby driving the flexible comb teeth 92 into the root system. During this process, the flexible comb teeth 92 can be slightly oscillated, so that they can better enter the root system and ensure that the flexible comb teeth 92 can cover the root growth area, efficiently comb the tangled roots, and ensure that the roots are spread out more evenly.

[0021] Please see Figure 6-9 The liquid supply mechanism 10 includes an annular spray head 101, which is embedded in the upper side of the assembly ring 91. Two hoses 102 are fixedly connected to the bottom ends of the annular spray head 101. A ring pipe 104 is fixedly connected between the two hoses 102. A fixing pipe 103 is fixedly connected to the bottom end of each hose 102. A water tank 107 is fixedly connected to the bottom end of the assembly base 6. A water pump 106 is fixedly connected to the top end of the water tank 107. The input pipe of the water pump 106 extends into the water tank 107. A three-way pipe 105 is fixedly connected to the output end of the water pump 106. The ring pipe 104 is fixedly connected to the three-way pipe 105. A liquid filling pipe 108 is fixedly connected to the bottom end of the water tank 107. The liquid filling pipe 108 has an L-shaped structure, and one side of the liquid filling pipe 108 is fixed... The cultivation cylinder 3 is connected to a solenoid valve 109. A strip-shaped hole 11 is opened on one side of the cultivation cylinder 3. One side of the L-shaped liquid filling pipe 108 extends out of the strip-shaped hole 11, which facilitates subsequent replenishment of liquid to the liquid filling pipe 108 with the help of equipment, and is slidably connected to the strip-shaped hole 11. Through the structure of annular spray head 101, hose 102, ring pipe 104, fixed pipe 103, water tank 107, water pump 106, and three-way pipe 105, water and fertilizer supply and spraying can be realized. The annular spray head 101 can cover the root growth area in all directions. With the root thinning mechanism 9, the roots can be spread out, so that the mist can penetrate the root cluster smoothly and spray better onto the root surface. This ensures that the roots absorb water and fertilizer evenly and avoids the situation of some roots drying out and some roots rotting. It provides sufficient nutritional support for the rapid propagation of potato seedlings and improves cultivation efficiency and seedling quality.

[0022] Please see Figure 3-4The mounting assembly 13 includes a mounting base 131, which is fixedly connected to both sides of the upper outer portion of the cultivation cylinder 3. The mounting base 131 has a sliding groove 132 inside, and an elastic locking block 133 is fixedly connected to one side of the sliding groove 132. A slider 134 is slidably connected inside the sliding groove 132, and locking holes 135 are provided on both sides of the slider 134. The elastic locking block 133 engages with the locking holes 135. The mounting assembly 131, the sliding groove 132, and the elastic locking block 134 are connected together. The main structures, such as the positioning ring 133, slider 134, and locking hole 135, enable the rapid installation of the required positioning ring 12, facilitating the transplanting of potato cultivation samples. At the same time, it ensures that the positioning ring 12 is installed firmly, effectively fixing the main body of the potato seedling, ensuring the stability of the root growth direction, reducing the root entanglement and knotting caused by seedling shaking, providing favorable conditions for root expansion and subsequent drainage and sap supply operations, and indirectly ensuring the quality of seedling cultivation and rapid propagation efficiency.

[0023] A cultivation method for a constant temperature and humidity potato seedling rapid propagation cultivation device includes the following steps: S1. Turn on the power of the incubator 1, set the initial temperature and humidity according to the needs of potato seedling cultivation, monitor in real time through temperature sensor 202 and humidity sensor 301 to ensure stable temperature and humidity in the cultivation chamber, inject the prepared potato seedling nutrient solution into the water tank 107 of the liquid supply mechanism 10, and close the solenoid valve 109. S2. Based on the size of the potato cultivation sample, select a suitable positioning ring 12 and fix the positioning ring 12 to the top of the cultivation cylinder 3 using the mounting component 13; push the slider 134 on one side of the positioning ring 12 so that it slides in the groove 132 of the card seat 131 until the elastic card block 133 in the card seat 131 is engaged in the card hole 135 of the slider 134, thus completing the fixing of the positioning ring 12; check the honeycomb mesh 302 inside the cultivation cylinder 3 to ensure that it is firmly fixed and undamaged, so as to avoid affecting root growth and equipment operation; S3. Select healthy, disease-free potato seedlings, pass the seedling roots through the through hole of the positioning ring 12, so that the seedling roots extend into the inner cavity of the cultivation cylinder 3, and fix the main body of the seedling by the positioning ring 12. Gently press the contact part between the positioning ring 12 and the seedling to ensure that the seedling is not shaken. S4. Close the lid 2 of the incubator 1, turn on the plant light 201, set the illumination time and brightness of the plant light 201 to provide sufficient light for the growth of potato seedlings, and monitor the temperature and humidity parameters in the incubator in real time through the temperature sensor 202 and the humidity sensor 301. If the temperature and humidity deviate from the set value, adjust them in time through the controller to maintain a constant temperature and humidity incubation environment. S5. When the potato seedling roots grow to a certain length, the power mechanism 5 is activated. The motor 51 drives the drive rod 52 to rotate. The worm gears 53 on both sides of the drive rod 52 drive the worm wheel 54 to rotate. The worm wheel 54 drives the lead screw 55 to rotate. The lead screw 55 drives the linkage block 58 to slide in the guide groove 57 of the fixed frame 4. The linkage block 58 drives the assembly seat 6 to move upward through the linkage rod 59. The assembly seat 6 drives the rubber top block 7 and the elastic top plate 8 to move upward synchronously. The conical rubber top block 7 is inserted into the root system and cooperates with the elastic top plate. 8. Initially disperse the tangled root clusters, and at the same time start the air pump 951 of the root thinning mechanism 9. The air pump 951 supplies air to the linkage empty rod 59 through the spring air pipe 952 and the air guide pipe, pushing the piston 954 to move upward. The piston 954 drives the assembly ring 91 to move through the push rod 955 and the push block 956. The assembly ring 91 drives the flexible comb teeth 92 to extend into the root system. During this process, the reciprocating component 95 drives the flexible comb teeth 92 to swing slightly, further combing the initially dispersed root system, so that the root system spreads out radially. S6. While the root system is being loosened, the water pump 106 of the liquid supply mechanism 10 is started. The water pump 106 draws out the nutrient solution in the water tank 107 and delivers it to the ring spray head 101 through the three-way pipe 105, the ring pipe 104, and the hose 102. The ring spray head 101 atomizes the nutrient solution and sprays it evenly onto the surface of the potato seedling root system. With the loosened root system, the nutrient solution is covered without dead corners. S7. Regularly open the incubator 1 lid 2 to check the growth status of potato seedlings, observe whether the roots are rotten or tangled, clean up the rotten roots in time, and check the operation status of the power mechanism 5, root thinning mechanism 9, and liquid supply mechanism 10. S8. When the potato seedlings grow to the appropriate age and meet the requirements for transplanting or breeding, stop the operation of the plant light 201, power mechanism 5, root thinning mechanism 9, and liquid supply mechanism 10. Open the cover 2 of the cultivation box 1, press the elastic block 133 in the card seat 131 to disengage it from the card hole 135 of the slider 134, push the slider 134, remove the positioning ring 12, and gently lift the potato seedlings upward to allow the seedling roots to be pulled out of the cultivation cylinder 3 and pass through the honeycomb mesh 302 to complete the seedling harvest. After harvesting, clean the cultivation cylinder 3, positioning ring 12, honeycomb mesh 302, and other components to prepare for the next batch of seedling cultivation.
