Description

Technical Field

[0001] This invention relates to the field of Anoectochilus roxburghii cultivation technology, specifically to a method for semi-wild selection and cultivation of Anoectochilus roxburghii under forest cover. Background Technology

[0002] Golden Thread Orchid (Anoectochilus roxburghii) is a rare medicinal plant with various significant medicinal and health benefits. Its optimal growth temperature is 16-28℃, requiring well-ventilated and humid environments, ideally under the cover of trees with "three parts sun and seven parts shade." Therefore, Golden Thread Orchid is considered one of the better species for developing understory economies. Previously, many practitioners explored understory cultivation of Golden Thread Orchid, but due to various reasons, the development was not ideal. Previously, the lack of proper light management in understory cultivation led to poor growth. Fertilization is crucial during the growth period, but fertilizer solutions can be quite damaging, easily burning the leaves.

[0003] In view of this, the applicant conducted in-depth research on the aforementioned deficiencies in the prior art, which led to this case. Summary of the Invention

[0004] The main objective of this invention is to provide a method for the semi-wild selection and cultivation of Anoectochilus roxburghii under forest cover, which can solve the problems of troublesome management and easy burning of leaves by fertilizer solution, thereby improving the planting efficiency of Anoectochilus roxburghii.

[0005] To achieve the above objectives, the solution of the present invention is:

[0006] A method for semi-wild selection and cultivation of Anoectochilus roxburghii under forest cover, comprising the following steps:

[0007] ① Site selection: Choose a planting site located under a tall tree forest with abundant water, good ventilation, coolness, and diffused light. The canopy closure of the upper layer of trees should be 70%-80%, and the vegetation coverage of the lower layer should be 35-45%. The soil should be loose, well-aerated, with a humus content of more than 5% and a pH of 6.0-6.5. All tree branches below 3m above the ground level of the planting site should be removed.

[0008] ② Remove weeds, branches, and dead leaves from the surface of the planting site and burn them at a location below the elevation of the planting site and far away from the planting site; loosen the soil and disinfect the planting site; after disinfection, let it stand for 12-15 days before ridging.

[0009] ③ During the disinfection and settling period of the planting site, a light intensity control shed is built above the planting site. The light intensity control shed has a first shading curtain and a second shading curtain that are spaced apart in the height direction.

[0010] ④ Prepare tissue culture seedlings. Tissue culture seedlings should be healthy seedlings with a height of 8-10cm and a root length of more than 2.5cm, and have 3-4 leaves. Planting should be carried out during the period from Rain Water to Spring Equinox when the average temperature rises above 16℃ for five consecutive days. The plant spacing should be 4-6cm. After planting, water thoroughly to help the roots settle. If there is no natural rainfall within 7 days after planting the tissue culture seedlings, water should be applied until the soil is moist 6cm below the surface.

[0011] ⑤ During the cultivation and growth period of Anoectochilus roxburghii, the daytime light intensity should be controlled at 3200-3800 lx. If the light is too strong, use a shading curtain to reduce the light intensity.

[0012] ⑥ Apply liquid fertilizer 25-35 days after planting. At the same time, spray water on the leaves of Anoectochilus roxburghii to wash off the liquid fertilizer.

[0013] ⑦ When the seedlings of *Anoectochilus roxburghii* reach a height of 12cm or more and have 5-6 leaves by the end of October to the beginning of November, they can be harvested. Harvesting should be done on sunny days with no rainfall in the two days prior to harvesting. Harvesting time is from 10:00 AM to 4:00 PM.

[0014] Furthermore, the liquid fertilizer in step ⑥ is biogas slurry diluted 500-800 times; potassium dihydrogen phosphate at a weight of 0.2% of the total weight of the liquid fertilizer can also be added to the liquid fertilizer.

[0015] Furthermore, step ②, removing weeds, branches, and dead leaves from the planting site surface, is achieved using a cleaning machine. This machine includes a trolley body, tracks, a shovel, and a mowing wheel. The tracks are located below the trolley body and have two sets, left and right. The trolley body has a receiving cavity. A feed inlet is located at the front of the trolley body, with a mounting frame extending forward from the front of the feed inlet. A mowing wheel is rotatably mounted on the mounting frame. A shovel extends from the lower end of the feed inlet to below the mowing wheel. A handle is located on the upper part of the trolley body, and an outlet is located on the side of the trolley body away from the feed inlet, with an openable tailgate. When the cleaning machine is working, the tracks drive the mowing wheel and shovel forward. The rotating mowing wheel cuts the weeds and pushes the weeds and dead branches towards the feed inlet.

[0016] Furthermore, the mowing reel has a first end plate, a second end plate, a central shaft, a deflector plate, and a spiral blade. The first end plate and the second end plate are arranged in parallel. The central shaft passes through the center of the first end plate and the second end plate and is fixedly connected to the first end plate and the second end plate. A plurality of spiral blades are fixedly connected to the first end plate and the second end plate at even intervals around the axis of the central shaft. The same number of deflector plates as the spiral blades are fixedly connected between the first end plate and the second end plate. The length direction of the deflector plate is parallel to the axial direction of the central shaft. A spiral blade is distributed between two adjacent deflector plates.

[0017] Furthermore, in step ③, the light intensity control shed has four uprights, with crossbars between adjacent uprights; the light intensity control shed has a rectangular horizontal cross-section, and a first steel wire rope and a second steel wire rope are horizontally arranged along the long side inside the shed. The first steel wire rope is higher than the second steel wire rope. The first light-blocking curtain is slidably mounted on the first steel wire rope, and the second light-blocking curtain is slidably mounted on the second steel wire rope; the first light-blocking curtain can be unfolded or retracted on one side of the first steel wire rope, and the second light-blocking curtain can be unfolded or retracted on one side of the second steel wire rope; the first light-blocking curtain... The first light-shielding strip is formed on the upper part of the light intensity control shed, extending along the long side of the light intensity control shed. The first light-shielding strip is evenly spaced along the wide side of the light intensity control shed, and adjacent first light-shielding strips are connected by first thin connecting strips. The second light-shielding curtain is formed on the upper part of the light intensity control shed, extending along the wide side of the light intensity control shed. The second light-shielding strip is evenly spaced along the long side of the light intensity control shed, and adjacent second light-shielding strips are connected by second thin connecting strips. All the first light-shielding strips occupy half of the total area of ​​the unfolded first light-shielding curtain, and all the second light-shielding strips occupy half of the total area of ​​the unfolded second light-shielding curtain.

[0018] Furthermore, the light intensity control shed also includes a first top net and a second top net located above the first shading curtain. The first and second top nets are provided with a light-transmitting mesh material, and the light transmittance of the mesh material inside the first and second top nets is greater than 95%. The first and second top nets are connected to the long side of the light intensity control shed. The mesh size of the first and second top nets is smaller than the size of the dead leaves of the trees above the planting site. The first and second top nets have an inclined angle compared to the horizontal plane.

[0019] Furthermore, a rotating rod is installed inside the light intensity control shed below the first and second top nets. Both ends of the rotating rod are rotatably connected to the crossbar via bearing seats. The length direction of the rotating rod is parallel to the long side of the light intensity control shed. A drive motor is installed at one end of the rotating rod. A sliding rod is installed below the rotating rod, parallel to the rotating rod, and both ends of the sliding rod are fixedly connected to the crossbar. An external thread is formed on the rotating rod, and a mounting seat is also installed on the rotating rod. A nut connected to the external thread is installed inside the mounting seat, and the mounting seat is slidably connected to the sliding rod below. A fan for cleaning fallen leaves is installed above the mounting seat, blowing towards the first and second top nets.

[0020] Furthermore, a top net vibration mechanism is provided between the first top net, the second top net, and the rotating rod. The top net frames of the first and second top nets are rotatably connected to the horizontal bar along the long side of the light intensity control shed, respectively. A first connecting rod and a second connecting rod are rotatably provided on the lower surface of the top net frames on the side close to each other of the first and second top nets. The top net vibration mechanism also includes an eccentric wheel, a connecting rod, a sliding rod, and a sliding seat. The eccentric wheel is fixedly connected to the rotating rod. The outer contour of the eccentric wheel is a cylindrical surface. The axis of the eccentric wheel is parallel to but not aligned with the axis of the rotating rod. One end of the connecting rod has a rotating ring, which is rotatably connected to the cylindrical surface of the eccentric wheel. The sliding seat is located above the rotating rod and is connected to the horizontal bar via a bracket. The sliding rod is slidably mounted on the sliding seat along the vertical direction. The upper end of the sliding rod is rotatably connected to both the first and second connecting rods, and the lower end of the sliding rod is rotatably connected to the end of the connecting rod away from the rotating ring.

[0021] Furthermore, the top net vibration mechanism consists of two sets, located on the outer sides of the two ends of the external thread on the rotating rod; the mounting base is equipped with a battery for supplying power to the wind turbine.

[0022] Furthermore, the fertilization with liquid fertilizer in step ⑥ is achieved through a spraying device, which includes a storage tank, a connecting pipe, and a spraying rod. The storage tank contains a fertilizer solution chamber and a clear water chamber. The connecting pipe has a first channel and a second channel. The first channel communicates with the fertilizer solution chamber, and the second channel communicates with the clear water chamber. The storage tank is also equipped with a first air pump and a second air pump to pressurize the fertilizer solution chamber and the clear water chamber, respectively. The spraying rod has a third channel and a fourth channel. The first channel communicates with the third channel, and the second channel communicates with the fourth channel. The spraying rod is also equipped with an on / off valve. The end of the spraying rod away from the connecting pipe is equipped with a first nozzle and a second nozzle. The first nozzle faces the first channel, and the second nozzle is located above the first nozzle. The first nozzle communicates with the third channel, and the second nozzle communicates with the fourth channel. The first nozzle outputs liquid fertilizer to the roots of the *Anoectochilus roxburghii*, and the second nozzle sprays clear water onto the leaves of the *Anoectochilus roxburghii*.

[0023] After adopting the above method, the forest-based semi-wild selection and cultivation method for *Anoectochilus roxburghii* (a type of orchid) of the present invention has at least the following beneficial effects:

[0024] I. This invention selects the area beneath tall trees as the planting site, choosing suitable light and soil conditions for *Anoectochilus roxburghii* growth, making full use of the understory space, and removing all tree branches within 3 meters of the planting site; this facilitates planting personnel and the construction of a light intensity control shed. The light intensity control shed is equipped with a first and second shading curtain to control the light intensity. After fertilization in step ⑥, the *Anoectochilus roxburghii* leaves are sprayed with clean water to avoid fertilizer burn.

[0025] 2. After planting the tissue culture seedlings in step ④, promptly add enough clean water to help them establish roots. If there is no natural rainfall within 7 days after planting, water them manually to ensure that the seedlings of Anoectochilus roxburghii have sufficient moisture.

[0026] 3. Harvesting of *Anoectochilus roxburghii* should be carried out two days after no rainfall to avoid excessive moisture and easy rotting after harvesting. The day of harvesting should be sunny, and harvesting should be carried out after the morning dew has dissipated. Due to the high danger in the forest at night, harvesting should be controlled during the daytime as much as possible, such as from 10:00 am to 4:00 pm. After 4:00 pm, the last batch of harvested *Anoectochilus roxburghii* should be transported down the mountain before dark.

[0027] Fourth, the planting site is cleaned using cleaning machinery. The tracks of the cleaning machinery have good passability and can adapt to forest paths and complex road conditions under the forest. When the cleaning machinery is in use, the mowing wheel rotates to cut the weeds. The shovel plate and the shovel plate on the mowing wheel work together to collect the weeds and dead branches into the receiving cavity, and then unload them and pile them up for subsequent processing. The location for burning the weeds, dead branches and fallen leaves is at an altitude lower than the planting site and far away from the planting site, so as to avoid the impact of pests and insect eggs on the weeds, dead branches and fallen leaves on the cultivation of Anoectochilus roxburghii.

[0028] 5. The first shading strip on the first shading curtain and the second shading strip on the second shading curtain are set vertically. When the first shading strip and the second shading strip are used at the same time, the light transmission area will be reduced by half compared to using the first shading strip or the second shading strip alone, so that the planting area after shading has a uniform shading effect.

[0029] Compared with existing technologies, this invention simplifies the cultivation and management of Anoectochilus roxburghii under forest cover by setting up a series of steps, which helps Anoectochilus roxburghii grow vigorously. Attached Figure Description

Detailed Implementation

[0045] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0046] like Figures 1 to 13 As shown, this invention relates to a method for the semi-wild selection and cultivation of Anoectochilus roxburghii under forest cover, comprising the following steps:

[0047] ① Site selection: Select a planting site 1 located under a tall tree forest with abundant water, good ventilation, coolness, and diffused light. The canopy closure of the upper layer of trees should be 70%-80%, and the vegetation coverage of the lower layer should be 35-45%. The soil should be loose, well-aerated, with a humus content of more than 5% and a pH of 6.0-6.5. All tree branches below 3m above the ground level of planting site 1 should be removed.

[0048] ② Site preparation and disinfection: Remove weeds, branches and dead leaves from the surface of planting site 1 and burn them at a location below the elevation of planting site 1 and far away from planting site 1; loosen the soil of planting site 1 and disinfect it; after disinfection, let it stand for 12-15 days before ridging.

[0049] ③ Constructing a light intensity control shed 2: During the disinfection and settling period of the planting site 1, a light intensity control shed 2 is constructed above the planting site 1. The light intensity control shed 2 has a first shading curtain 25 and a second shading curtain 26 that are spaced apart in the height direction.

[0050] ④ Planting tissue culture seedlings: Prepare tissue culture seedlings. The seedlings should be healthy, 8-10cm tall, with roots over 2.5cm long, and have 3-4 leaves. Plant them during the period from Rain Water to Spring Equinox, when the average temperature rises above 16℃ for five consecutive days. The plant spacing should be 4-6cm. Water thoroughly after planting to help the roots establish. If there is no natural rainfall within 7 days after planting the tissue culture seedlings, water until the soil is moist at a depth of 6cm. After planting the tissue culture seedlings in step ④, water thoroughly to help the roots establish. If there is no natural rainfall within 7 days after planting, water manually to ensure that the seedlings of *Anoectochilus roxburghii* have sufficient moisture.

[0051] ⑤ Control light intensity during planting: During the growing period of Anoectochilus roxburghii, the daytime light intensity should be controlled at 3200-3800 lx. If the light is too strong, use a shading curtain to reduce the light intensity.

[0052] ⑥ Fertilizer management: Apply liquid fertilizer 25-35 days after planting. At the same time, spray water on the leaves of Anoectochilus roxburghii to wash off the liquid fertilizer.

[0053] ⑦ Harvesting: Golden Thread Orchids can be harvested when they reach a height of 12cm or more and have 5-6 leaves by late October to early November. Harvesting should be done on sunny days, with no rainfall within two days prior to harvest. Harvesting time is from 10:00 AM to 4:00 PM. Harvesting should be done two days after no rainfall to prevent the harvested golden thread or orchids from becoming too moist and rotting. The day of harvest should be sunny, and harvesting should begin after the morning dew has dissipated. Due to the higher risk of danger in the forest at night, harvesting should be controlled during the daytime, such as from 10:00 AM to 4:00 PM. After 4:00 PM, the last batch of harvested golden thread orchids should be transported down the mountain before dark.

[0054] Following the above method, this invention relates to a method for the semi-wild cultivation of *Anoectochilus roxburghii* under forest cover. This invention selects the area beneath tall trees as planting site 1, choosing suitable light and soil conditions for *Anoectochilus roxburghii* growth, fully utilizing the understory space, and removing all tree branches within 3 meters of the planting site; this facilitates planting personnel and the construction of a light intensity control shed 2. The light intensity control shed 2 is equipped with a first shading curtain 25 and a second shading curtain 26 for controlling light intensity. After fertilization in step ⑥, the leaves of *Anoectochilus roxburghii* are sprayed with clean water to avoid fertilizer burn damage to the leaves.

[0055] Preferably, the liquid fertilizer in step ⑥ is biogas slurry diluted 500-800 times; potassium dihydrogen phosphate at 0.2% by weight of the total liquid fertilizer can also be added to the liquid fertilizer. Applying the diluted biogas slurry to the roots of *Anoectochilus roxburghii* supplements the nutrients needed by *Anoectochilus roxburghii*, which helps to increase the yield of *Anoectochilus roxburghii*.

[0056] Preferably, such as Figures 2 to 8 As shown, in step ③, the light intensity control shed 2 has four columns 21, and a crossbar 22 is set between adjacent columns 21. The light intensity control shed 2 has a rectangular horizontal cross section. A first steel wire rope 23 and a second steel wire rope 24 are horizontally arranged along the long side inside the light intensity control shed 2. The first steel wire rope 23 is higher than the second steel wire rope 24, and the two ends of the first steel wire rope 23 and the second steel wire rope 24 are fixedly connected to the crossbar 22. The first light-blocking curtain 25 is slidably mounted on the first steel wire rope 23, and the second light-blocking curtain 26 is slidably mounted on the second steel wire rope 24. The first light-blocking curtain 25 can be unfolded or stored on one side of the first steel wire rope 23, and the second light-blocking curtain 26 can be unfolded or stored on the second steel wire rope 24. On one side of 4; a plurality of first light-shielding strips 251 extending along the long side of the light intensity control shed 2 are formed on the first light-shielding curtain 25, and the plurality of first light-shielding strips 251 are evenly spaced along the wide side of the light intensity control shed 2, and adjacent two first light-shielding strips 251 are connected by a first thin connecting strip 252; a plurality of second light-shielding strips 261 extending along the wide side of the light intensity control shed 2 are formed on the second light-shielding curtain 26, and the plurality of second light-shielding strips 261 are evenly spaced along the long side of the light intensity control shed 2, and adjacent two second light-shielding strips 261 are connected by a second thin connecting strip 262; all the first light-shielding strips 251 occupy half of the total area of ​​the first light-shielding curtain 25 after unfolding, and all the second light-shielding strips 261 occupy half of the total area of ​​the second light-shielding curtain 26 after unfolding.

[0057] The first thin connecting strip 252 and the second thin connecting strip 262 serve a connecting function. Due to their thinness, they have almost no impact on the light transmission area between the shading strips. The first shading strip 251 on the first shading curtain 25 and the second shading strip 261 on the second shading curtain 26 are arranged vertically. When the first shading strip 251 and the second shading strip 261 are used simultaneously, the light transmission area will be reduced by half compared to using the first shading strip 251 or the second shading strip 261 alone, thus ensuring a uniform shading effect on the planted area. Figure 7 As shown, when the first and second blackout curtains 25 and 26 are not in use, they are stored to one side. When it is necessary to unfold the first and second blackout curtains 25 and 26, it is done manually or by a device that can move the first and second blackout curtains 25 and 26 along the first and second steel wire ropes 23 and 24, such as a mobile robot (not shown in the figure) that crawls along the first or second steel wire rope 23 or 24. A light intensity indicator 29 is also installed in the planting area 1. By measuring the light intensity for the growth of *Anoectochilus roxburghii* in real time, it reminds the manager to adjust the blackout curtains in a timely manner or communicates with the mobile robot to automatically control the state of the first and second blackout curtains 25 and 26 according to the light intensity.

[0058] To prevent fallen leaves from landing on the *Anoectochilus roxburghii* and the first and second shading curtains 25 and 26, preferably, the light intensity control shed 2 also includes a first top net 27 and a second top net 28 located above the first shading curtain 25. The first and second top nets 27 and 28 contain a light-transmitting mesh material, with a light transmittance greater than 95%. The first and second top nets 27 and 28 are connected to the long side of the light intensity control shed 2. The mesh size of the first and second top nets 27 and 28 is smaller than the size of fallen leaves from trees above the planting area 1. The first and second top nets 27 and 28 have an angle of inclination relative to the horizontal plane. The structure of the first and second top nets 27 and 28 is similar to that of a screen window, with the internal mesh structure made of a highly light-transmitting material, effectively blocking fallen leaves while avoiding interference with light. The first top net 27 and the second top net 28 are designed to be inclined, forming a sloping roof structure above the light intensity control shed 2. Fallen leaves on the first top net 27 and the second top net 28 can move to both sides of the light intensity control shed 2 on their own under the influence of gravity and natural wind disturbance. Because the first top net 27 and the second top net 28 have a mesh structure, rainwater can pass through them smoothly, allowing the planting area 1 to still receive natural rainwater.

[0059] If fallen leaves continue to accumulate, causing both the first and second shading curtains 25 and 26 to be lower than the light intensity required for the growth of *Anoectochilus roxburghii* after being retracted; preferably, a rotating rod 31 is provided inside the light intensity control shed 2 below the first and second top nets 27 and 28, with both ends of the rotating rod 31 rotatably connected to the crossbar 22 via bearings 311, and the length direction of the rotating rod 31 being parallel to the long side of the light intensity control shed 2; a drive motor 312 is provided at one end of the rotating rod 31; the rotating rod 31 A sliding rod 32 is provided below, parallel to the rotating rod 31, and both ends of the sliding rod 32 are fixedly connected to the crossbar 22; an external thread 313 is formed on the rotating rod 31, and a mounting seat 33 is also provided on the rotating rod 31, with a nut connected to the external thread 313 inside the mounting seat 33, and the lower part of the mounting seat 33 is slidably connected to the sliding rod 32; a fan 331 for cleaning fallen leaves is provided above the mounting seat 33, blowing towards the first top net 27 and the second top net 28. By using a fan 331, fallen leaves are blown away from the first top net 27 and the second top net 28 by manually blowing air from bottom to top at an angle. In operation, a drive motor 312 rotates the rotating rod 31, which is threadedly connected to a nut on the mounting base 33. Therefore, the mounting base 33 moves along the axis of the rotating rod 31. The sliding rod 32 keeps the upper surface of the mounting base 33 facing upwards and ensures that the mounting base 33 can move smoothly along the axis as the rotating rod 31 rotates. Since the blowing area of ​​a single fan 331 is limited, the threaded structure on the rotating rod 31 allows the fan 331 to sweep over most of the area of ​​the first top net 27 and the second top net 28 during movement, ensuring effective leaf removal.

[0060] Preferably, to further improve the removal effect of fallen leaves on the first top net 27 and the second top net 28, such as... Figures 4 to 6 As shown, a top net vibration mechanism 34 is provided between the first top net 27, the second top net 28 and the rotating rod 31. The top net frames of the first top net 27 and the second top net 28 are rotatably connected to the horizontal bar 22 in the long side direction of the light intensity control shed 2. A first connecting rod 345 and a second connecting rod 346 are rotatably provided on the top net frame on the lower surface of the side of the first top net 27 and the second top net 28 that are close to each other. Preferably, the mesh structure of the first top net 27 and the second top net 28 is provided on the upper surface of the top net frame and is flush with the upper surface of the top net frame to reduce the number of fallen leaves caught on the mesh material in the middle of the top net frame.

[0061] The top net vibration mechanism 34 also includes an eccentric wheel 341, a connecting rod 342, a sliding rod 343, and a sliding seat 344. The eccentric wheel 341 is fixedly connected to the rotating rod 31. The outer contour of the eccentric wheel 341 is cylindrical. The axis of the eccentric wheel 341 is parallel to but not aligned with the axis of the rotating rod 31. One end of the connecting rod 342 has a rotating ring 3421, which is rotatably connected to the cylindrical surface of the eccentric wheel 341. The sliding seat 344 is located above the rotating rod 31 and is connected to the crossbar 22 via a bracket 3441. The sliding rod 32 is slidably mounted on the sliding seat 344 along the vertical direction. The upper end of the sliding rod 32 is rotatably connected to both the first connecting rod 345 and the second connecting rod 346, and the lower end of the sliding rod 32 is rotatably connected to the end of the connecting rod 342 away from the rotating ring 3421.

[0062] When the rotating rod 31 rotates, the mounting base 33 moves axially, and the fan 331 blows air, the top net vibration mechanism 34 drives the top net frames of the first top net 27 and the second top net 28 to reciprocate around the outer axis, causing fallen leaves to be shaken off the inclined first top net 27 and the second top net 28. For each rotation of the rotating rod 31, the mounting base 33 moves one pitch. The first top net 27 and the second top net 28 complete one cycle of oscillation. Although the amplitude of a single oscillation is small, the mounting base 33 travels a certain distance from one side of the external thread 313 to the other. The rotating rod 31 rotates a sufficient number of times at a relatively high speed, thus requiring the first top net 27 and the second top net 28 to reciprocate multiple times at high frequency. Combined with the blowing force of the fan 331, the two work together to allow the fallen leaves to be blown off the first top net 27 and the second top net 28 more smoothly. For example, if the pitch of the external thread 313 on the rotating rod 31 is 2cm and the rotating rod 31 rotates at a speed of 30 revolutions per minute, then the mounting base 33 will move along the axis of the rotating shaft at a speed of 60cm / min, and the reciprocating vibration frequency of the first top net 27 and the second top net 28 is 30 times / min; preferably, two fans 331 are provided on the mounting base 33, respectively facing the first top net 27 and the second top net 28.

[0063] Preferably, there are two sets of top net vibration mechanisms 34, located on the outer sides of the two ends of the external thread 313 on the rotating rod 31; the mounting base 33 is provided with a battery for supplying power to the fan 331. If the length of the rotating rod 31 is too long, multiple external threads 313 can be provided on the rotating rod 31, each external thread 313 is provided with a set of mounting bases 33, and a set of top net vibration mechanisms 34 is also provided between each two adjacent external thread segments 313.

[0064] Preferably, such as Figure 10 and Figure 11 As shown, step ②, clearing weeds, branches, and dead leaves from the surface of planting site 1, is achieved using a cleaning machine 4. The cleaning machine 4 includes a cart body 41, a walking track 42, a shovel 43, and a mowing wheel 44. The walking track 42 is located below the cart body 41 and has two sets, left and right. The cart body 41 has a receiving cavity 411. A feed inlet 412 is located at the front of the cart body 41, and a mounting frame 413 extends forward from the front of the feed inlet 412. A mowing wheel is rotatably mounted on the mounting frame 413. 44. A shovel 43 extending below the mowing wheel 44 is formed at the lower end of the feed inlet 412; a handle 414 is provided on the upper part of the trolley body 41; a discharge port 415 is provided on the side of the trolley body 41 away from the feed inlet 412; the discharge port 415 is provided with an openable tailgate 416; when the cleaning machine 4 is working, the walking track 42 drives the mowing wheel 44 and the shovel 43 to move forward, the mowing wheel 44 rotates to cut weeds and pushes weeds and dead branches toward the feed inlet 412. The cleaning machine 4 is used to clean the planting site 1. The walking track 42 of the cleaning machine 4 has good passability and can adapt to forest paths and complex road conditions under the forest; the trolley body 41 is provided with a power source (such as a gasoline engine or a battery and an electric motor), the power source drives the walking track 42 and the mowing wheel 44 to rotate through a transmission mechanism, the transmission mechanism is a conventional structure that can be designed by those skilled in mechanical design. In use, the user holds the handle 414 and controls the direction of the cleaning machine 4 and the rotation of the mowing wheel 44 through the direction control mechanism on the handle. The discharge port 415 is provided with a tailgate 416. When unloading is required, the tailgate 416 opens to unload the weeds and dead branches in the receiving cavity 411.

[0065] Preferably, such as Figure 11As shown, the mowing wheel 44 has a first end plate 441, a second end plate 442, a central shaft 443, a pawl 444, and spiral blades 445. The first end plate 441 and the second end plate 442 are arranged parallel to each other. The central shaft 443 passes through the center of the first end plate 441 and the second end plate 442 and is fixedly connected to the first end plate 441 and the second end plate 442. A plurality of spiral blades 445 are fixedly connected to the first end plate 441 and the second end plate 442 at even intervals around the axis of the central shaft 443. The same number of pawls 444 as the spiral blades 445 are fixedly connected between the first end plate 441 and the second end plate 442. The length direction of the pawl 444 is parallel to the axis of the central shaft 443. A spiral blade 445 is distributed between two adjacent pawls 444. The spiral blades mainly serve to cut the grass. The spiral blades 445 are provided with cutting edges. When the mowing wheel 44 rotates, the cutting edges cut the weeds.

[0066] When the cleaning machine 4 is in use, the mowing wheel 44 rotates to cut the weeds. The shovel 43 and the shovel 444 on the mowing wheel 44 cooperate to collect the weeds and dead branches into the receiving cavity 411, and unload them and pile them up for subsequent processing. The location for burning the weeds, dead branches and fallen leaves is at an altitude lower than the planting site 1 and far away from the planting site 1, so as to avoid the pests and insect eggs on the weeds, dead branches and fallen leaves from affecting the planting of Anoectochilus roxburghii.

[0067] like Figures 12 to 13 As shown, preferably, the fertilization with liquid fertilizer in step ⑥ is achieved by a spraying device 5. The spraying device 5 includes a storage tank 51, a connecting pipe 52, and a spraying rod 53. The storage tank 51 has a fertilizer liquid chamber 511 and a clear water chamber 512. The connecting pipe 52 has a first channel 521 and a second channel 522. The first channel 521 is connected to the fertilizer liquid chamber 511, and the second channel 522 is connected to the clear water chamber 512. The storage tank 51 is also equipped with a first air pump 513 and a second air pump 514 to pressurize the fertilizer liquid chamber 511 and the clear water chamber 512, respectively. When the pressure of the fertilizer liquid chamber 511 and the clear water chamber 512 is insufficient, the first air pump 513 and the second air pump 514 pressurize the fertilizer liquid chamber 511 and the clear water chamber 512 by pumping air into them, so that the first nozzle 533 and the second nozzle 534 can spray out liquid fertilizer and clear water smoothly. Furthermore, the liquid storage tank 51 is equipped with a shoulder strap, allowing the liquid storage tank 51 to be carried on the operator's back, or the liquid storage tank 51 can be mounted on a trolley, and the liquid storage tank 51 can be moved by moving the trolley, thereby reducing the operator's labor intensity.

[0068] The spray rod 53 has a third channel 531 and a fourth channel 532. The first channel 521 is connected to the third channel 531, and the second channel 522 is connected to the fourth channel 532. The spray rod 53 is also equipped with an on / off valve 54. The end of the spray rod 53 away from the connecting pipe 52 is equipped with a first nozzle 533 and a second nozzle 534. The first nozzle 533 faces the first nozzle, and the second nozzle 534 is located above the first nozzle 533. The first nozzle 533 is connected to the third channel 531, and the second nozzle 534 is connected to the fourth channel 532. The first nozzle 533 outputs liquid fertilizer to the roots of the Anoectochilus roxburghii, and the second nozzle 534 sprays water onto the leaves of the Anoectochilus roxburghii. By using a specially designed spraying device 5 with a first nozzle 533 and a second nozzle 534, after opening the on / off valve 54, the liquid fertilizer in the fertilizer chamber 511 is transported to the first nozzle 533 through the first channel 521 and the third channel 531, while the clear water in the clear water chamber 512 is transported to the second nozzle 534 through the second channel 522 and the fourth channel 532. Since the second nozzle 534 is higher than the first nozzle 533, the distance between the second nozzle 534 and the first nozzle 533 is 15cm, preferably 18cm. Thus, when the liquid fertilizer is delivered to the roots of the *Anoectochilus roxburghii*, even if a small amount of splashed fertilizer falls on the leaves, it will be washed away by the second nozzle 534. Due to the special design of the spraying device 5, there is no need to spray clear water after fertilization; instead, clear water is sprayed simultaneously with the liquid fertilizer during fertilization, achieving integrated operation and simplifying the operation steps.

[0069] Compared with existing technologies, this invention simplifies the cultivation and management of Anoectochilus roxburghii under forest cover by setting up a series of steps, which helps Anoectochilus roxburghii grow vigorously.
