Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plant cultivation technology, specifically relating to a plant micro-cutting in vitro propagation system. Background Technology
[0002] Cutting propagation is a form of asexual reproduction in plant propagation. It involves taking a healthy branch, leaf, or root from the mother plant, treating it appropriately, inserting it into a suitable substrate, and allowing it to take root and sprout in a suitable artificial environment, growing into a new plant with the same genetic characteristics as the mother plant. When the cultivation volume is small, appropriate equipment is needed for micro-cutting operations.
[0003] The patent specification with announcement number CN221996238U discloses a horticultural plant cutting propagation device, including a cultivation box body, a motor fixedly installed on one side of the cultivation box body, the output shaft of the motor fixedly connected to a lead screw, a nut seat movably installed on the outside of the lead screw, a movable block fixedly installed on the top of the nut seat, a guide rod movably installed on the inner wall of the movable block, an installation plate fixedly installed on the bottom of the nut seat, and a plant lighting lamp fixedly installed on the bottom of the installation plate.
[0004] Multiple cuttings are typically propagated at once to improve cultivation efficiency. However, this type of propagation device has several drawbacks. First, the cuttings within the cultivation box need uniform lighting to prevent uneven growth. The device uses a motor to drive a lead screw with a light fixture mounted on it, attempting to provide even illumination to all cuttings. However, the motor can only move a single light fixture on the lead screw. Furthermore, the cuttings are planted not only directly below the light fixture but also across the entire bottom surface. Switching from a single-point to a single-line lighting mode still fails to provide uniform lighting to the entire bottom surface. Uniform lighting means that the device cannot effectively provide uniform lighting for multiple cuttings, maintaining a consistent growth environment for each cutting. Secondly, the use of artificial cultivation boxes is not only for the survival of cuttings, but more importantly, for hardening off the cuttings so that they gradually adapt to the external natural environment and develop the ability to survive independently. The light and ventilation intensity of the device remains constant. However, the root system of cuttings is weak in the early stages. The high temperature caused by excessive light and the strong ventilation system will evaporate the existing water in the upper part of the plant too quickly, while the water absorption capacity of the bottom roots is not yet fully developed. In other words, the use of this device will increase the probability of damage to the cuttings in the early stages.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] The purpose of this utility model is to provide a plant micro-cutting in vitro propagation system. The technical problem to be solved is as follows: when cultivating multiple cuttings, the existing plant cutting devices cannot provide uniform light to the cuttings, and the cuttings have a high probability of damage in the early stage of use.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] A plant micro-cutting in vitro propagation system includes a base, a box body mounted on top of the base, and multiple disassembly and assembly mechanisms installed along the circumferential side of the base and the box body. Ventilation mechanisms are provided on both sides of the middle section of the box body, each ventilation mechanism including an adjustable vent fixedly connected to the box body. A humidification mechanism is provided on top of the box body, and a lighting mechanism is provided inside the box body above the humidification mechanism, with adjustable light intensity. The disassembly and assembly mechanisms, ventilation mechanisms, and lighting mechanism are all used for hardening off the cuttings. Frosted glass is installed inside the box body below the lighting mechanism, and a power outlet is installed on one side of the box body.
[0009] As a further embodiment of this utility model: the disassembly and assembly mechanism includes a plug rod fixedly connected to the outer side of the base, a slide rod slidably connected to the top of the box, a baffle fixedly connected to the inner end of the slide rod located in the box, a spring fixedly connected to the baffle near the inner wall of the box, and a locking strip fixedly connected to the outer end of the slide rod located in the box, the bottom of the locking strip being sleeved with the plug rod.
[0010] As a further embodiment of this utility model: the ventilation mechanism also includes two slots fixedly connected to the outside of the box, a baffle plate slidably connected between the two slots, straight slot holes are provided on both sides of the baffle plate, a locking handle is threadedly connected between the bottom of the slot and the box, and the middle of the locking handle passes through the straight slot hole.
[0011] As a further embodiment of this utility model: the humidification mechanism includes a humidification chamber fixedly connected to the outside of the box body, a humidifier is placed inside the humidification chamber, a main pipe is installed on one side of the humidifier, and a branch ring pipe is connected to one end of the main pipe extending into the inside of the box body. Multiple atomizing nozzles are evenly installed along the circumferential side of the branch ring pipe, and the bottom of each atomizing nozzle is clustered towards the center of the box body, and all of them form an angle of 30-50 degrees with the vertical plane.
[0012] As a further embodiment of this utility model: the lighting mechanism includes a lamp plate installed on the top of the box, a lamp adjuster installed on one side of the box, the lamp plate being electrically connected to the lamp adjuster, and a plurality of heat dissipation holes being evenly arranged along the circumferential side of the top of the box.
[0013] As a further embodiment of this utility model: the bottom of the base is provided with a limiting ring chamber, the bottom of the box body is inserted into the outer peripheral side of the limiting ring chamber, a plurality of support rods are fixedly connected in the middle of the limiting ring chamber, a cultivation plate is fixedly connected between the top ends of each support rod, a plurality of cultivation chambers are evenly arranged on the cultivation plate, and the bottom of each cultivation chamber is suspended.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up multiple cultivation chambers in the base and installing a light panel with frosted glass on the top of the box, the cuttings in the multiple cultivation chambers can receive more uniform and natural light conditions by using the multi-point light source of the LED beads on the light panel and the light diffusion of the frosted glass. The purpose is to provide uniform light conditions for each cutting to control their growth rate and make it easier for each cutting to be at the same growth stage during the subsequent hardening-off process, thus avoiding damage to some cuttings during hardening-off.
[0016] 2. By installing ventilation mechanisms on both sides of the box, airflow channels are created during ventilation. The size of the ventilation openings can be controlled by adjusting the baffles, thereby controlling the air circulation efficiency and the rate of water evaporation from the cuttings. An adjustable light switch is used in conjunction with the lighting mechanism to provide different levels of light intensity for different stages of the cuttings' hardening-off process. This prevents excessive water loss and low survival rates caused by immature root systems. Furthermore, in the later stages of hardening-off, the disassembly mechanism can be used to... The base of the seedlings is easily separated from the top box, allowing the cuttings to adapt locally to the external natural temperature variation environment. This is achieved by adjusting the ventilation efficiency of the ventilation mechanism, adjusting the light intensity and temperature of the lighting mechanism, and the convenient external placement of the cuttings through the later disassembly mechanism. Combined with uniform lighting to provide a unified growth environment for the survival and growth of multiple cuttings in the early stages, this constitutes an integrated and stable cultivation scheme for multiple cuttings, and improves the overall survival rate of all cuttings from the initial growth stage to the stage where they can be transplanted to the natural environment.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] like Figures 1 to 6 As shown, a plant micro-cutting in vitro propagation system includes a base 1, a box 2 mounted on top of the base 1, and four disassembly / assembly mechanisms 3 installed along the circumferential side between the base 1 and the box 2. Ventilation mechanisms 4 are provided on both sides of the middle of the box 2, each including a vent 41 fixedly connected to the box 2, the size of which is adjustable. A humidification mechanism 5 is provided on top of the box 2 for humidifying the cuttings. A lighting mechanism 6 is provided inside the box 2, above the humidification mechanism 5, with adjustable light intensity. The disassembly / assembly mechanisms 3, ventilation mechanisms 4, and lighting mechanism 6 are all used for hardening off the cuttings. Frosted glass 7 is installed inside the box 2 between the humidification mechanism 5 and the lighting mechanism 6.
[0027] It should be noted that the bottom of base 1 (see...) Figure 3A limiting ring chamber is set up, and the outer periphery of the limiting ring chamber is used to insert into the box body 2. Multiple support rods are fixedly connected to the bottom of the limiting ring chamber, and a cultivation board is fixedly connected between the tops of each support rod. Twelve cultivation chambers are evenly arranged on the cultivation board. The bottom of each cultivation chamber is suspended and located above the limiting ring chamber. A water passage hole (not shown) is set at the bottom of each cultivation chamber. That is, the pool inside the limiting ring chamber is used to collect the water leakage when watering the cuttings, so as to prevent water from accumulating in the cultivation chamber and causing root rot. In addition, four slots 8 are evenly arranged along the edge of the bottom of the base 1. The top of the box body 2 is fitted with each slot 8 and fixedly connected to the slots 8. The slot 9 is a platform with a small top and a large bottom. It is used for stacking the system. The platform shape avoids the risk of stacking and slipping, and also facilitates the separation of each system, thereby improving the space utilization of the system. At the same time, a power socket 10 is installed in the middle of the box body 2. The power socket 10 includes a power outlet and a power off switch to supply power to the humidification mechanism 5 and the lighting mechanism 6.
[0028] like Figure 1 and Figure 5 As shown, the disassembly and assembly mechanism 3 includes a plug rod 31 fixedly connected to the outer side of the base 1, a slide rod 32 slidably connected to the top of the box 2, a baffle 33 fixedly connected to the inner end of the slide rod 32, a spring 34 fixedly connected to the baffle 33 near the inner wall of the box 2, and a locking strip 35 fixedly connected to the outer end of the slide rod 32, with the bottom of the locking strip 35 sleeved with the plug rod 31.
[0029] It should be noted that when docking the base 1 and the box 2, the box 2 can be engaged by snapping it along the outer ring surface of the limiting ring compartment. Then, the locking strip 35 is moved on the outside of the box 2, and the sliding rod 32, which is fixedly connected to the locking strip 35, extends outward of the box 2 and compresses the internal spring 34. At the same time, the inner side of the locking strip 35 extends outward beyond the outermost end of the insertion rod 31 and aligns with the bottom through hole of the locking strip 35. Simultaneously, the locking strip 35 is released, and the spring 34 contracts, causing the bottom of the locking strip 35 to engage with the insertion rod 31. This achieves the assembly between the base 1 and the box 2. When disassembling, the locking strip 35 can be moved outward again, and the sliding rod 32 can be rotated to place the locking strip 35 on one side of the insertion rod 31. At this time, the base 1 and the box 2 are in a separated state. The purpose is to facilitate the disassembly and assembly of the various cultivation compartments during the cutting process, and further, to provide convenience for subsequent seedling hardening.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the ventilation mechanism 4 also includes two slots 42 fixedly connected to the outside of the housing 2. A baffle plate 43 is slidably connected between the two slots 42. Straight slot holes 44 are provided on both sides of the baffle plate 43. A locking handle 45 is threaded between the bottom of the slot 42 and the housing 2. The middle of the locking handle 45 passes through the straight slot hole 44.
[0031] It should be noted that the ventilation requirements for cuttings differ during the cultivation and hardening-off processes. Specifically, the initial ventilation requirement is less than that in the later stages. Therefore, during actual ventilation, workers can loosen the two locking handles 45 of the ventilation mechanism 4, then push the wind deflector 43 to slide along the slots 42 on both sides to expose the ventilation opening 41 to a suitable size. After that, the locking handles 45 are tightened to fix the position of the wind deflector 43, thereby achieving the function of controlling the ventilation level.
[0032] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the humidification mechanism 5 includes a humidification chamber 51 fixedly connected to the outside of the box 2. A humidifier 52 is placed inside the humidification chamber 51. A main pipe 53 is installed on one side of the humidifier 52. The main pipe 53 extends into the inside of the box 2 and connects to the branch ring pipe 54. Atomizing nozzles 55 are installed at the bottom of each branch ring pipe 54. The bottom of each atomizing nozzle 55 is clustered towards the center of the box 2. Specifically, they are all at a 45-degree angle to the vertical plane.
[0033] It should be noted that in addition to watering the roots of the cuttings during the cutting process, it is also necessary to control the humidity of the stems and leaves to avoid water shortage. The humidifier 52 controls the humidity inside the box 2 through the atomizing nozzle 55. Since the atomizing nozzle 55 is located diagonally above each cutting, in order to avoid uneven water vapor input vertically downward, water vapor is added by installing the atomizing nozzle 55 diagonally downward, thereby improving the uniformity of internal humidification.
[0034] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the lighting mechanism 6 includes a lamp plate 61 installed on the top of the housing 2. A lamp switch 62 is electrically connected to the lamp plate 61 on one side of the housing 2. Multiple heat dissipation holes 11 are evenly arranged on the top of the housing 2 along the circumferential side. The heat dissipation holes 11 are used to provide heat dissipation channels for the lamp plate 61 during operation.
[0035] It should be noted that the lamp board 61 is a lamp fixture with LED beads evenly arranged on a substrate. When it is located above each cultivation chamber, the light emitted is more uniform. Combined with the frosted glass 7 at the bottom of the lamp board 61, the light in the system is closer to natural light and maintains uniform light for all cuttings. This provides uniform light growth conditions for each cutting. Furthermore, the light intensity can be adjusted by the lamp adjuster 62. Specifically, the lamp adjuster 62 has a built-in potentiometer to adjust the resistor and is equipped with a corresponding drive circuit to convert the voltage and current through the lamp board 61 when adjusting the resistor, thereby realizing the brightness adjustment of the LED beads. The lamp adjuster 62 is equipped with a brightness percentage adjustment indicator and a corresponding knob (this is prior art) on the outside. The purpose is to control the uniform growth process of each cutting by uniformly irradiating the light intensity and to adjust the light intensity at each stage of the growth process to improve the overall survival rate of each cutting.
[0036] Working principle:
[0037] After placing the detached cuttings into the respective cultivation chambers on the base 1, the cultivators first perform germination and planting. At this stage, a relatively large amount of water needs to be applied to each cultivation chamber. Since the cuttings have not yet developed root systems and their water absorption capacity is limited, after assembling the box 2 and base 1 using the disassembly and assembly mechanism 3, only a small number of ventilation openings 41 are opened. The light intensity of the lamp panel 61 is also maintained at a low level by the lamp adjuster 62. When a gentle lift of the cutting reveals resistance and white roots appear in the water passage at the bottom of the cultivation chamber, it indicates that the cutting has survived. As the root system grows stronger during the hardening-off stage, the ventilation openings 41 are gradually opened to increase ventilation intensity, and the light intensity is gradually increased to approach natural light. After the upper stems and leaves of the cuttings have grown, the box 2 is opened through the disassembly mechanism 3 and the box 2 is separated from the base 1. Each cutting is exposed to the natural environment for a period of time to allow it to adapt to the temperature changes in the external environment. This allows the cuttings to gradually adapt to the external natural growth environment and improves their survival rate when transplanted.
[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
