Description

Technical Field

[0001] This invention relates to the field of plant preservation technology, and in particular to a device and process for preserving poplar branches. Background Technology

[0002] *Pterocarya stenoptera* is a shrub or small tree belonging to the genus *Pterocarya* of the family Pentaphyllaceae. It can reach a height of 16 meters, with grayish-brown bark, cylindrical branches, brown twigs, and terminal buds covered in grayish-brown appressed short, soft hairs. During transportation, storage, and sale after harvesting, *Pterocarya stenoptera* branches are easily dehydrated, wilted, discolored, and rotten due to the separation from the parent plant's water and nutrient supply, severely impacting their ornamental and commercial value.

[0003] In order to inhibit the growth of pathogens such as bacteria, viruses and fungi and reduce the risk of branch rot, existing branch preservation devices usually install ultraviolet lamps inside. However, ultraviolet lamps can only irradiate one side of the poplar branches, and the irradiation angle is limited, resulting in poor effectiveness. Summary of the Invention

[0004] The purpose of this invention is to provide a device and process for preserving and processing poplar branches, which solves the technical problem that the ultraviolet lamp has a limited irradiation angle and poor effect in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the enclosure includes: an enclosure door hinged to the enclosure; a temperature regulator installed on the side of the enclosure for regulating the temperature inside the enclosure; a bracket installed on the inner wall of the enclosure; and a boss installed on the inner bottom surface of the enclosure.

[0008] Preferably, the insert mechanism further includes: an internal toothed ring, installed on the bottom surface of the fixed plate; and multiple external toothed rings, respectively fixedly sleeved on multiple rotating cylinders, wherein the multiple external toothed rings are meshed with the internal toothed ring.

[0009] Preferably, the rotating cylinder comprises: a clamping slot, which is opened at the top of the rotating cylinder; a valve, which is installed on the bottom surface of the rotating cylinder; the inserting cylinder comprises: a connecting rod, which is fixedly connected with the inserting cylinder and is in inserting fit with the clamping slot; a strip-shaped groove, which penetrates through the side surface of the inserting cylinder.

[0010] Preferably, the driving mechanism comprises: a motor, which is installed on the convex platform; a shaft rod, which is arranged in a zigzag shape, one end of which is fixedly connected with the rotating plate, and the other end of which is fixedly connected with the power output shaft of the motor.

[0011] Preferably, the liquid spraying mechanism further comprises: a hollow ring, which is installed on the inner top surface of the box body; a plurality of atomizing nozzles, all of which are installed on the bottom surface of the hollow ring; a water pump, which is installed on the top surface of the water tank, the water suction pipe of which extends into the water tank, and the water outlet pipe of which is fixedly connected and communicated with the hollow ring.

[0012] Preferably, the stirring assembly comprises: two vertical rods, both of which penetrate through the bottom surface of the water tank and are rotatably connected with the water tank; a plurality of stirring rods, which are respectively installed on the two vertical rods; two second gears, which are respectively installed at the lower ends of the two vertical rods.

[0013] Preferably, the linkage mechanism comprises: a cross rod, which is slidably connected with the bracket; a strip-shaped ring member, which is sleeved on the shaft rod and is slidably connected with the shaft rod; a plurality of teeth, which are respectively installed on both sides of the cross rod in the length direction, and the teeth are in meshing fit with the second gear.

[0014] A fresh-keeping treatment process for Eurya japonica branches, comprising the following steps:

[0015] Step one, Eurya japonica branch selection: select Eurya japonica branches with a diameter of 0.8-1.2 cm, a length of 60-80 cm and bright color.

[0016] Step two, picking: complete the picking 2-3 hours after sunrise or 2-3 hours before sunset.

[0017] Step three, cleaning: rinse the Eurya japonica branches with flowing water to remove soil, insect eggs and other attachments on the Eurya japonica branches.

[0018] Step four, pruning: prune the Eurya japonica branches to a length of 40-50 cm, remove the leaves 5-10 cm at the bottom of the Eurya japonica branches, and remove excess leaves and side branches at the same time.

[0019] Step five, storage: inject the fresh-keeping treatment liquid into a plurality of rotating cylinders, insert the lower ends of the Eurya japonica branches into the floral foam in the inserting cylinders, then place a plurality of inserting cylinders inserted with Eurya japonica branches into the rotating cylinders, so that the floral foam can absorb the fresh-keeping treatment liquid.

[0020] Step 6, UV irradiation: Turn on the UV lamp, and then start the motor to drive the rotating plate to rotate. When the rotating plate rotates, it will drive the rotating cylinder and the insert to rotate around the center of the rotating plate. The rotating cylinder and the insert will also rotate on their own axis. When the insert rotates, it will also drive the poplar branches inside the insert to rotate, so that the UV lamp can irradiate multiple poplar branches more comprehensively.

[0021] Step 7, Temperature Control; Set the temperature inside the chamber between 2-6℃;

[0022] Step 8, Spraying the Preservative Treatment Liquid: The humidity control system regulates the air humidity inside the box through a water pump, which then delivers the preservative treatment liquid from the water tank to the hollow ring. The liquid is then sprayed onto the poplar branches through multiple atomizing nozzles, increasing the humidity inside the box and keeping the poplar branches moist.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. The poplar branch preservation device of this invention is equipped with an ultraviolet lamp, a box, an insertion mechanism, and a drive mechanism. Multiple poplar branches are inserted into the insertion mechanism, and then the ultraviolet lamp is activated to irradiate the branches. The drive mechanism then rotates a rotating plate, causing multiple rotating cylinders and insertion cylinders to rotate around the center of the rotating plate. This allows the ultraviolet lamp to irradiate multiple poplar branches from multiple angles. Ultraviolet light can destroy the DNA structure of microorganisms, effectively inhibiting the growth of pathogens such as bacteria, viruses, and fungi, reducing the risk of rotting during storage and transportation. Simultaneously, ultraviolet light can induce plants to produce secondary metabolites such as flavonoids, which have antioxidant and antibacterial effects, helping to enhance the disease resistance and preservation effect of the poplar branches.

[0025] 2. The spraying mechanism in this invention is equipped with a water tank, a water inlet, a water pump, a hollow ring, atomizing nozzles, and a stirring assembly. By starting the water pump, the water pump delivers the preservation liquid in the water tank to the hollow ring, and then sprays the preservation liquid onto the poplar branches through multiple atomizing nozzles, so as to keep the poplar branches moist.

[0026] 3. The poplar branch preservation device of the present invention is configured with a shaft, a crossbar, a strip-shaped ring, teeth, a bracket, and a second gear. When the motor drives the shaft to rotate, it drives the strip-shaped ring and the crossbar to move back and forth horizontally, which in turn drives the two second gears to rotate intermittently. This, in turn, drives the vertical rod and the stirring rod to intermittently stir the preservation liquid in the water tank. Intermittent stirring can prevent the preservation liquid from separating into layers and reduce the generation of bubbles, thereby obtaining a more stable mixing effect and avoiding the generation of a large number of bubbles due to continuous stirring.

[0027] 4. The preservation process for poplar branches in this invention involves selecting healthy, disease-free branches, pruning and removing excess leaves to reduce moisture evaporation, and then using ultraviolet irradiation, temperature control, and spraying with a preservation solution to effectively extend the shelf life of poplar branches. This allows the branches to maintain their fresh green state and good quality for a longer period of time, meeting the needs of long-term storage and transportation. Attached Figure Description

[0041] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0042] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figures 1-12 As shown, a device for preserving and treating *Pterocarya stenoptera* branches includes a housing 100, an ultraviolet lamp 103, a branch insertion mechanism 200, a drive mechanism 300, a spraying mechanism 400, and a linkage mechanism 500.

[0045] The enclosure 100 includes a door 101, a temperature regulator 102, a bracket 104, and a boss 105. The door 101 is hinged to the front of the enclosure 100; the temperature regulator 102 is installed on the side of the enclosure 100, and its temperature regulating pipe extends into the enclosure 100; the temperature regulator 102 is used to regulate the temperature inside the enclosure 100; the bracket 104 is installed on the inner wall of the enclosure 100; and the boss 105 is installed on the inner bottom surface of the enclosure 100. An ultraviolet lamp 103 is installed on the inner wall of the enclosure 100.

[0046] The insert mechanism 200 includes a fixed plate 201, an internal toothed ring 203, a rotating plate 210, multiple rotating cylinders 220, multiple insert cylinders 230, and multiple external toothed rings 222.

[0047] A fixed plate 201 is fixedly connected to the inner wall of the housing 100. Multiple drainage holes 202 are formed through the fixed plate 201. An internal toothed ring 203 is installed on the bottom surface of the fixed plate 201. A circular groove is formed at the center of the fixed plate 201, and a rotating plate 210 passes through this groove and is rotatably connected to the rotating plate 210. Multiple rotating cylinders 220 pass through the rotating plate 210 and are rotatably connected to it. Multiple inserts 230 are inserted into the rotating cylinders 220 respectively. Floral foam is placed inside the inserts 230 to facilitate the insertion of poplar branches. Multiple external toothed rings 222 are fixedly fitted onto the rotating cylinders 220 respectively, and are engaged with the internal toothed rings 203. When the rotating plate 210 rotates, it will drive multiple rotating cylinders 220 and insert cylinders 230 to rotate around the center of the rotating plate 210. Since the outer toothed ring 222 is meshed with the inner toothed ring 203, when the rotating cylinder 220 drives the outer toothed ring 222 to rotate, the rotating cylinder 220 will rotate on its own, which in turn will drive the insert cylinder 230 to rotate on its own.

[0048] The drive mechanism 300 is located inside the housing 100 and is used to drive the rotating plate 210 to rotate. The spraying mechanism 400 is used to spray the preservative treatment liquid onto the poplar branches. The spraying mechanism 400 includes a water tank 401 and a stirring assembly 410. The water tank 401 is used to hold the preservative treatment liquid. The stirring assembly 410 is used to stir the preservative treatment liquid in the water tank 401.

[0049] Specifically, multiple poplar branches are inserted into the floral foam inside multiple inserts 230. Then, the ultraviolet lamp 103 is activated to irradiate the poplar branches. The drive mechanism 300 is then activated, causing the rotating plate 210 to rotate. This causes the multiple rotating cylinders 220 and inserts 230 to rotate around the center of the rotating plate 210. Since the outer toothed ring 222 is meshed with the inner toothed ring 203, when the rotating cylinder 220 drives the outer toothed ring 222 to rotate, the rotating cylinder 220 will rotate on its own axis, which in turn causes the inserts 230 to rotate on their own axis. This allows the ultraviolet lamp 103 to irradiate the multiple poplar branches from multiple angles. At the same time, the linkage mechanism 500 also drives the stirring component 410 to intermittently stir, preventing the preservation liquid in the water tank 401 from separating into layers.

[0050] like Figure 6 and Figure 9 As shown, the rotating cylinder 220 includes a slot 221 and a valve 223. The slot 221 is located at the top of the rotating cylinder 220; the valve 223 is installed on the bottom surface of the rotating cylinder 220, and by opening the valve 223, the preservation liquid inside the rotating cylinder 220 can be easily discharged.

[0051] The insertion cylinder 230 includes a connection rod 231 and a strip-shaped groove 232. The connection rod 231 is fixedly connected to the insertion cylinder 230, and the connection rod 231 is in insertion fit with the clamping groove 221. By providing the connection rod 231 and the clamping groove 221, relative rotation between the insertion cylinder 230 and the rotating cylinder 220 can be avoided when the insertion cylinder 230 is inserted into the rotating cylinder 220; the strip-shaped groove 232 is penetratingly opened on the side surface of the insertion cylinder 230.

[0052] As shown in Figures 5-9 and Figures 10-12 , the driving mechanism 300 includes a motor 301 and a shaft rod 302; the motor 301 is mounted on the boss 105; the shaft rod 302 is arranged in a "zigzag" shape, one end of the shaft rod 302 is fixedly connected to the rotating plate 210, and the other end of the shaft rod 302 is fixedly connected to the power output shaft of the motor 301.

[0053] Specifically, when the motor 301 operates, it will drive the shaft rod 302 to rotate, and further drive the rotating rod to rotate.

[0054] As shown in Figures 4-7 and Figure 10 , the liquid spraying mechanism 400 further includes a hollow ring 404, a water inlet hopper 402, a plurality of atomizing nozzles 405 and a water pump 403.

[0055] The hollow ring 404 is mounted on the inner top surface of the box body 100; the plurality of atomizing nozzles 405 are all mounted on the bottom surface of the hollow ring 404, and the atomizing nozzles 405 communicate with the hollow ring 404. The water pump 403 is mounted on the top surface of the water tank 401, the water suction pipe of the water pump 403 extends into the water tank 401, and the water outlet pipe of the water pump 403 is fixedly connected and communicates with the hollow ring 404. One end of the water inlet hopper 402 penetrates one side of the box body 100 and one side of the water tank 401, and the water inlet hopper 402 communicates with the interior of the water tank 401.

[0056] As shown in Figure 11 and Figure 12 , the stirring assembly 410 includes two vertical rods 411, a plurality of stirring rods 412 and two second gears 413.

[0057] The two vertical rods 411 both penetrate the bottom surface of the water tank 401 and are rotatably connected with the water tank 401; the plurality of stirring rods 412 are all located inside the water tank 401, and the plurality of stirring rods 412 are respectively mounted on the two vertical rods 411. The two second gears 413 are respectively mounted at the lower ends of the two vertical rods 411.

[0058] Specifically, when the two gears rotate, they will drive the two vertical rods 411 to rotate, and further drive the plurality of stirring rods 412 to rotate. When the plurality of stirring rods 412 rotate, they will stir the fresh-keeping treatment liquid in the water tank 401, thereby avoiding delamination and segregation of the fresh-keeping treatment liquid.

[0059] As shown in Figures 5-9 , Figure 11 and Figure 12 As shown, the linkage mechanism 500 includes a crossbar 501, a strip-shaped ring 502, and multiple teeth 503.

[0060] A groove 504 is provided on the bottom surface of the crossbar 501. The crossbar 501 is slidably connected to the bracket 104 through the groove 504. The crossbar 501 can only move horizontally left and right relative to the bracket 104. The strip-shaped ring 502 is sleeved on the shaft 302. The adjusting ring is slidably connected to the shaft 302. Multiple teeth 503 are respectively installed on both sides of the crossbar 501 along its length. The teeth 503 mesh with the second gear 413. A square groove is provided through one side surface of the housing 100. The crossbar 501 can pass through the square groove.

[0061] Specifically, when the shaft 302 rotates, the shaft 302 will drive the strip ring 502 to move back and forth left and right, which in turn will drive the crossbar 501 to move back and forth left and right. When the teeth 503 on the crossbar 501 mesh with the second gear 413, the movement of the crossbar 501 will drive the rotation of the second gear 413.

[0062] Working principle: In actual use, the preservation liquid is injected into multiple rotating cylinders 220, the floral foam is placed in the insert 230, the poplar branches are covered with an elastic ring net, the lower end of the poplar branches is inserted into the floral foam in the insert 230, and then multiple insert 230s with poplar branches inserted are placed into the rotating cylinders 220, so that the connecting rod 231 on the insert 230 is inserted into the slot 221 on the insert 230, so that the floral foam can absorb the preservation liquid.

[0063] The preservation solution is then added to the water inlet tank 401 via the water inlet hopper 402. The tank door 101 is then closed, and the ultraviolet lamp 103 is turned on. The ultraviolet light irradiates the poplar branches, which can damage the DNA structure of microorganisms, effectively inhibiting the growth of pathogens such as bacteria, viruses, and fungi, and reducing the risk of rotting during storage and transportation. Appropriate ultraviolet irradiation can also inhibit plant physiological activities, such as respiration and enzyme activity, thereby slowing down the aging process of the poplar branches and extending their shelf life. Simultaneously, ultraviolet light can induce plants to produce secondary metabolites such as flavonoids, which have antioxidant and antibacterial effects, helping to enhance the disease resistance and preservation effect of the poplar branches. Furthermore, appropriate ultraviolet irradiation can increase the content of beneficial components such as chlorophyll and vitamin C in the poplar branches, improving their nutritional value and ornamental quality.

[0064] At the same time, by starting the motor 301, the power output shaft of the motor 301 drives the shaft 302 to rotate, which in turn drives the rotating plate 210 to rotate. When the rotating plate 210 rotates, it will drive multiple rotating cylinders 220 and insert cylinders 230 to rotate around the center of the rotating plate 210. Since the outer gear ring 222 is meshed with the inner gear ring 203, when the rotating cylinder 220 drives the outer gear ring 222 to rotate, the outer gear ring 222 meshing with the inner gear ring 203 will also cause the rotating cylinder 220 to rotate, which in turn drives the insert cylinder 230 to rotate. When the insert cylinder 230 rotates, it will also drive the poplar branches inside the insert cylinder 230 to rotate, so that the ultraviolet lamp 103 can irradiate multiple poplar branches more comprehensively.

[0065] Furthermore, when the shaft 302 rotates, it drives the strip ring 502 to move back and forth, which in turn drives the crossbar 501 to move back and forth. When the teeth 503 on the crossbar 501 mesh with the second gear 413, the movement of the crossbar 501 will drive the rotation of the second gear 413. When the two second gears 413 rotate, they will drive the two vertical rods 411 to rotate, which in turn will drive the multiple stirring rods 412 to rotate. When the multiple stirring rods 412 rotate, they will stir the preservation liquid in the water tank 401, thereby preventing the preservation liquid from separating into layers.

[0066] When the teeth 503 on the crossbar 501 are not engaged with the second gear 413, the movement of the crossbar 501 will not drive the rotation of the second gear 413. When the motor 301 drives the shaft 302 to rotate, it will drive the strip ring 502 and the crossbar 501 to move back and forth horizontally, thereby driving the two second gears 413 to rotate intermittently, which in turn drives the vertical rod 411 and the stirring rod 412 to intermittently stir the preservation treatment liquid in the water tank 401. Intermittent stirring can prevent the preservation treatment liquid from separating into layers, and can also reduce the generation of bubbles, thereby obtaining a more stable mixing effect and avoiding the generation of a large number of bubbles due to continuous stirring.

[0067] When the temperature inside the chamber 100 is higher than the preset temperature range, the temperature regulator 102 can be activated to adjust the temperature inside the chamber 100, thereby slowing down the physiological activity of the poplar branches and extending the shelf life.

[0068] When the humidity inside the chamber 100 is lower than the preset value, the water pump 403 is started, which transports the preservation liquid in the water tank 401 to the hollow ring 404. The preservation liquid is then sprayed onto the poplar branches through multiple atomizing nozzles 405, thereby increasing the humidity inside the chamber 100 and keeping the poplar branches moist.

[0069] The preservation solution mentioned above can be a commercially available plant preservation solution, or it can be prepared by oneself according to the patent publication number CN102511474B (the patent name is a method for producing a pretreatment mother liquor for the preservation of cut branches of *Pterocarya stenoptera*).

[0070] Example 2

[0071] like Figures 1-12 As shown, while all other parts are the same as in Example 1, the difference between this embodiment and Example 1 is that: a device for preserving and treating poplar branches also includes a humidity control system for adjusting the air humidity inside the box 100, and the humidity control system includes a data acquisition module, a data processing module and a control module.

[0072] The data acquisition module is used to collect the air humidity inside the housing 100; the data processing module is used to receive the data from the data acquisition module and determine whether a processing instruction needs to be generated; the control module is used to generate a control instruction based on the processing instruction, and the control instruction is to adjust the running time of the water pump 403.

[0073] The data processing module determines whether an adjustment command needs to be generated as follows:

[0074] Receive the user's preset air humidity threshold inside the box and mark the preset air humidity threshold as H1;

[0075] The humidity inside the chamber is recorded by the data acquisition module and labeled as H0.

[0076] If H0 ≥ H1, no adjustment command will be generated;

[0077] If H0 < H1, then an adjustment command is generated;

[0078] Then, based on the formulas ΔH=H1-H0 and ΔH=k*τ+H0, the required running time of water pump 403 is calculated; the data acquisition module sends the calculated running time of water pump 403 to the control module, which then controls the start of water pump 403.

[0079] In the formula, H1 is the preset air humidity threshold, H0 is the initial humidity inside the chamber 100 before the water pump 403 is turned on, ΔH is the increase in humidity, τ is the duration of the water pump 403 being turned on, and k is a constant representing the efficiency of multiple atomizing nozzles in increasing the humidity inside the chamber per unit time.

[0080] By adjusting the operating time of water pump 403, the spray volume of the atomizing nozzle can be precisely controlled, thereby achieving precise regulation of the humidity inside the box 100. This helps maintain a stable humidity level inside the box 100 and meets the storage requirements of the poplar branches.

[0081] Meanwhile, the water pump 403 is activated based on the humidity level inside the enclosure 100, avoiding unnecessary energy waste. Furthermore, by setting up a humidity control system, automated and intelligent management of the humidity inside the enclosure 100 can be achieved, reducing the burden of manual operation, improving management efficiency, and minimizing the risk of improper humidity control due to human error.

[0082] The method for obtaining the value of k is as follows:

[0083] Prepare a hygrometer that can accurately measure humidity, and install the hygrometer inside the box 100;

[0084] Select a set of initial and target humidity values, and determine the operating duration range of the spray mechanism 400. For example, start with 5 seconds and increase by 5 seconds each time until a reasonable maximum duration is reached; for each selected spray duration, record the humidity values ​​before and after spraying. Ensure that the chamber 100 is returned to its initial state between each experiment to eliminate the influence of the previous experiment.

[0085] For each spray duration, calculate the increase in humidity ΔH. Then, plot a scatter plot with the spray duration τ on the x-axis and the increase in humidity ΔH on the y-axis.

[0086] By observing the trend of the scatter plot, if the data points are roughly distributed along a straight line, then a linear regression method can be used to fit these data points and obtain the slope of the line. This slope is an estimate of k.

[0087] Finally, several verification experiments were conducted using the obtained k value to check whether the predicted increase in humidity was close to the actual measured value.

[0088] Example 3

[0089] like Figures 1-12 As shown, a preservation process for poplar branches includes the following steps:

[0090] Step 1, Selection of Populus euphratica branches: Select Populus euphratica branches with a diameter of 0.8 cm, a length of 60 cm, and a bright color. Avoid selecting Populus euphratica branches that are too old, too young, or have obvious mechanical damage.

[0091] Step two, harvesting: Harvesting should be completed 2-3 hours after sunrise;

[0092] Step 3, Cleaning: Use running water to clean the poplar branches to remove soil, insect eggs and other attached substances;

[0093] Step 4, pruning: Prune the poplar branches to a length of 40 cm, remove the leaves from the bottom 5 cm of the branches, and remove excess leaves and side branches to reduce water evaporation and nutrient consumption.

[0094] Step 5, storage: By injecting preservation liquid into multiple rotating cylinders 220, insert the lower end of the poplar branch into the floral foam in the insert 230, and then place multiple inserts 230 with poplar branches inserted into the rotating cylinder 220 so that the floral foam can absorb the preservation liquid.

[0095] Step 6, Ultraviolet Irradiation: When the ultraviolet lamp 103 is turned on and the motor 301 is started to drive the rotating plate 210 to rotate, the rotating plate 210 will drive multiple rotating cylinders 220 and insert cylinders 230 to rotate around the center of the rotating plate 210. Since the outer toothed ring 222 is meshed with the inner toothed ring 203, when the rotating cylinder 220 drives the outer toothed ring 222 to rotate, the rotating cylinder 220 and insert cylinder 230 will rotate. When the insert cylinder 230 rotates, it will also drive the poplar branches inside the insert cylinder 230 to rotate, so that the ultraviolet lamp 103 can irradiate multiple poplar branches more comprehensively.

[0096] Step 7, Temperature Control: Set the temperature inside the chamber 100 to between 2℃;

[0097] Step 8, spraying preservation solution: The humidity control system starts the water pump 403, which delivers the preservation solution in the water tank 401 to the hollow ring 404, and then sprays the preservation solution onto the poplar branches through multiple atomizing nozzles 405, thereby increasing the humidity in the box 100 and keeping the poplar branches moist.

[0098] By selecting healthy, disease-free branches and pruning away excess leaves to reduce moisture evaporation, and then using ultraviolet radiation, temperature control, and spraying with preservative solution, the shelf life of Yangtongxie branches can be effectively extended. This allows the branches to maintain their fresh green color and good quality for a longer period of time, meeting the needs of long-term storage and transportation.
