Description

Technical Field

[0001] This invention relates to the field of Dendrobium officinale cultivation technology, specifically to a Dendrobium officinale trunk cultivation device and cultivation method, which is particularly suitable for the epiphytic semi-wild cultivation of Dendrobium officinale on living trees. Background Technology

[0002] Dendrobium officinale is a perennial epiphytic herb belonging to the genus Dendrobium in the family Orchidaceae. It has extremely high medicinal and economic value. Epiphytic cultivation on living trees, mimicking natural growth, is a planting method for Dendrobium officinale that has been promoted in recent years. This involves planting Dendrobium officinale seedlings on living tree trunks, allowing them to grow in a natural environment, thereby improving the quality of the medicinal material.

[0003] The existing trunk epiphytic cultivation devices mainly have the following problems: Firstly, most existing cultivation devices are fixed structures, with the angle between the sidewall of the V-shaped groove and the trunk fixed. This makes it impossible to adjust according to light conditions, seasonal changes, and plant growth stages, thus failing to meet the planting needs of different seasons.

[0004] Secondly, existing devices are usually monolithic structures that need to be customized according to the trunk diameter, making them unsuitable for trunks of different thicknesses. This makes installation and operation inconvenient and hinders large-scale promotion. Summary of the Invention

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a Dendrobium officinale trunk cultivation device, which aims to achieve flexible adjustment of the V-shaped groove sidewall angle, adapt to trunks of different thicknesses, ensure continuous sealing of the sidewall, and enable tool-free and quick installation.

[0006] The technical solution of this invention is as follows: A Dendrobium officinale trunk cultivation device includes: The binding strap is a long, flexible strip whose length is cut on-site according to the circumference of the tree trunk. The binding strap is wrapped around the tree trunk once and the two ends overlap, and it is fixed to the tree trunk by locking devices. The outer circumference of the binding strap has multiple slots spaced along the length direction, while the inner circumference has several vertical saw-shaped anti-slip teeth.

[0007] The umbrella has multiple ribs, including a plug section and a support section. The lower end of the plug section is inserted into the slot and fixed. The lower end of the support section is hinged to the upper end of the plug section. Multiple threading holes are spaced apart on the outer side of the support section along its length.

[0008] Multiple ring-shaped tie members are respectively inserted into the threading holes at various height positions of each of the support segments. Each ring-shaped tie member surrounds the tree trunk and is fixed end to end. The circumference diameter of each ring-shaped tie member is determined according to the target unfolding angle, so that each ring-shaped tie member together constrains multiple support segments to the same unfolding angle.

[0009] Flexible planting bags are laid on the inner side of multiple support sections, forming a V-shaped planting space between the flexible planting bags and the tree trunk to accommodate the cultivation substrate.

[0010] Preferably, the annular tie is a bidirectional cable tie, which is threaded together end to end to form an annular loop. Its effective length can be adjusted in both directions to enlarge or reduce the diameter of the loop.

[0011] Preferably, the bidirectional cable tie does not need to be cut during adjustment; the length of the loop can be changed by pulling the protruding ends of the cable tie, thereby achieving stepless adjustment of the umbrella rib unfolding angle.

[0012] Preferably, the locking element is iron wire or steel wire, which is wrapped around the overlapping section of the binding tape at least two times and then twisted and tightened to secure the binding tape to the tree trunk.

[0013] Preferably, the locking element is a one-way cable tie, with a cable tie buckle at one end and the other end passing through the cable tie buckle and then tightened and self-locked in one direction.

[0014] Preferably, the flexible planting bag is a long strip of non-woven fabric or waterproof fabric, the width of which is greater than the length of the support section. The upper edge of the flexible planting bag is folded over to wrap around the top of each support section, and the bottom is folded up to a certain height to cover the tree trunk.

[0015] Preferably, the annular tie members in each ring are adjusted according to the same target unfolding angle. The annular tie member with the smallest diameter is inserted through the lower wire hole, and the annular tie member with the largest diameter is inserted through the higher wire hole. All annular tie members in each ring maintain the same taper.

[0016] The present invention also provides a planting method based on the above-mentioned cultivation device, comprising the following steps: Step 1: Secure with cable ties Take a long strip of flexible binding tape, cut it on site according to the circumference of the tree trunk, wrap the binding tape around the tree trunk once, overlap the two ends, and fix it to the tree trunk with locking devices; Step Two: Installing and Erecting the Umbrella Ribs Insert the lower end of the insertion section of each umbrella rib into the slot on the outer periphery of the strapping tape and fix it so that each umbrella rib is spaced apart along the length of the strapping tape. Flip the support section of each umbrella rib upward around the hinge point and stand it upright. Step 3: Angle Adjustment Take a ring-shaped tie and thread it through the threading hole at the same height position of each of the support segments, so that the ring-shaped tie wraps around the trunk and is fixed at both ends, thus constraining multiple support segments to the same unfolding angle. Step 4: Laying planting bags and epiphytic planting A flexible planting pouch is laid on the inner side of multiple support sections to form a V-shaped planting space between the flexible planting pouch and the trunk; the cultivation substrate is filled into the V-shaped planting space, and the Dendrobium officinale seedlings are planted in the cultivation substrate.

[0017] The advantages of this invention are: (i) Adjustable angle: By setting threading holes of different heights on each support section and using multi-ring tie pieces (two-way cable ties), the umbrella rib support section can be adjusted to different unfolding angles as needed, achieving stepless adjustment from 30° to 60° to adapt to the light requirements of different seasons.

[0018] (ii) Adaptable to any tree diameter: The binding strap is a long, flexible strip that can be cut on-site according to the trunk circumference and secured to the trunk with locking devices, eliminating the need for customization. The serrated anti-slip teeth on the inner circumference of the binding strap embed into the bark texture when locked, effectively preventing the device from slipping.

[0019] (iii) Continuous sealing of side walls: The flexible planting bag is laid on the inside of the support section. No matter what the support section is at the unfolding angle, the flexible planting bag can naturally fit the shape of the umbrella rib, maintain the continuity of the side walls, and fundamentally prevent substrate leakage.

[0020] (iv) Tool-free quick installation: The umbrella rib connector is fixed by inserting it into the cable tie slot; the ring tie uses a two-way cable tie, and the angle can be adjusted by pulling both ends without tools; the locking part can be made of wire or one-way cable tie, which can be completed with simple tools or even by hand.

Detailed Implementation

[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1-4 As shown: Basic structure and installation The present invention is mainly composed of a binding strap 2, multiple umbrella ribs 3, multiple ring-shaped tie members 4, and a flexible planting bag 5.

[0025] The binding strap 2 is a long, flexible strip made of polyester fiber or nylon, with a width of 30-60mm and a thickness of 2-3mm. The length of the binding strap 2 is cut on-site according to the circumference of the tree trunk 1, and after wrapping around the tree trunk 1 once, the two ends overlap and are fixed to the tree trunk 1 by the locking device 6.

[0026] The outer periphery of the binding strap 2 has multiple slots 21 spaced along its length. The slots 21 are any one of dovetail grooves, T-shaped grooves, or straight-insertion square holes, used to fix the insertion section 31 of the umbrella rib 3. The inner periphery of the binding strap 2 has several vertically serrated anti-slip teeth 22. After locking, the anti-slip teeth 22 can embed into the bark texture, significantly increasing the friction and effectively preventing the device from sliding down the tree trunk under the action of gravity, thus improving the stability of long-term use.

[0027] The umbrella rib 3 includes a connector section 31 and a support section 32. The lower end of the connector section 31 is inserted into and fixed in a slot 21, and its cross-sectional shape matches that of the slot 21. The connector section 31 can be easily removed from the slot 21 for convenient replacement of individual umbrella ribs. The lower end of the support section 32 is hinged to the upper end of the connector section 31 via a hinge shaft 33 or a rivet. The support section 32 can rotate relative to the connector section 31 around the hinge point. Multiple threading holes 34 are spaced apart along the length of the support section 32, preferably 3-5 holes.

[0028] Multiple ring-shaped tie members 4 are respectively inserted into the threading holes 34 at various height positions of each support section 32. The same ring-shaped tie member 4 is inserted into the threading hole 34 at the same height position. Each ring-shaped tie member 4 is wrapped around the trunk 1 and fixed end to end. Its circumference diameter is determined according to the target unfolding angle, so that each ring-shaped tie member 4 together constrains multiple support sections 32 at the same unfolding angle.

[0029] Each ring-shaped tie member 4 is adjusted according to the same target unfolding angle. The ring-shaped tie member 4 with the smallest diameter is inserted through the low-position threading hole, and the ring-shaped tie member 4 with the largest diameter is inserted through the high-position threading hole. Each ring-shaped tie member 4 maintains the same taper to ensure that the unfolding angle of all umbrella rib support sections 32 is consistent and the V-groove shape is uniform.

[0030] The flexible planting pouch 5 is laid inside the multiple support sections 32. It is a long strip of non-woven fabric or waterproof cloth, and its width is greater than the length of the support section 32. The upper edge of the flexible planting pouch 5 is folded over to wrap around the top of each support section 32 to form an upward folded edge 51, and the bottom is folded up to a certain height to wrap around the trunk 1 to form a downward folded edge 52. After filling with substrate, the bottom will naturally press against the trunk and seal the bottom end. A V-shaped planting space for containing cultivation substrate is formed between the flexible planting pouch 5 and the trunk 1. When using non-woven fabric, there are no holes at the bottom. If waterproof cloth is used, drainage holes are made at the bottom, and a filter pad needs to be placed on the drainage holes.

[0031] The ring tie 4 is preferably a two-way tie. The two-way tie is threaded together to form a ring. Its effective length can be adjusted in both directions to enlarge or reduce the ring diameter, and to achieve stepless adjustment of the umbrella rib opening angle. There is no need to cut the tie after the adjustment process, which is convenient for repeated adjustment next time.

[0032] The two-way cable ties are made of UV-resistant nylon PA66, with a width of 4.8-7.6mm, a length of 200-800mm (depending on the trunk diameter), a black color, and a tensile strength of ≥150kg.

[0033] The locking element 6 is used to fix both ends of the binding strap 2 to the tree trunk 1, and can be done in the following two ways: Method 1: Locking with iron or steel wire Wrap the wire or steel wire around the overlapping section of the binding tape 2 at least two times, then twist and tighten it to secure the binding tape 2 to the tree trunk 1. To fix it, first wrap the cut binding tape 2 around the tree trunk 1 once, overlapping the ends. Then, tightly wrap the wire or steel wire around the overlapping section 2-3 times. Next, twist and tighten the ends of the wire with pliers, cut off the excess, and the binding tape is now secured. This method is suitable for large tree diameters or heavy loads, offering high strength and resistance to aging.

[0034] Method 2: One-way cable tie locking After the unidirectional cable tie is threaded through the cable tie buckle and tightened, the unidirectional teeth inside the buckle engage with the toothed strips on the surface of the cable tie to achieve unidirectional self-locking. Excess cable tie is cut off. This method is suitable for small and medium-sized trees and general load scenarios. No tools are required and installation can be completed in seconds.

[0035] Angle adjustment principle The angle adjustment is achieved by changing the diameter of each ring-shaped tie member 4. The specific principle is as follows: The insertion section 31 is inserted into the slot 21 of the binding strap 2 and remains fixed, while the support section 32 rotates around the hinge axis 33. The distance from the threading holes 34 at different heights on the support section 32 to the center of the tree trunk is different—the lower threading holes are closer to the tree trunk, and the higher threading holes are farther away from the tree trunk.

[0036] When the diameters of all the ring-shaped tie members 4 change synchronously, the support section 32 is constrained at different angles: Reduce the angle (approximately 30°, summer strong light mode): Tighten the bidirectional ties in each loop simultaneously, reduce the ring diameter, minimize constraint at the low-position hole, maximize constraint at the high-position hole, and converge the support section 32 towards the trunk, making the V-shaped groove deeper and steeper. At this point, the groove is deeper, the substrate capacity is larger, and the shading effect is better, suitable for summer strong light environments, reducing water evaporation.

[0037] Magnification angle (approximately 60°, low-light winter mode): All double-sided ties are simultaneously loosened, the ring diameter is enlarged, the support section 32 is extended away from the trunk, and the V-groove becomes shallower and gentler. At this time, the amount of light incident increases, suitable for the low-light winter environment, improving the plant's photosynthetic efficiency.

[0038] Median angle (approximately 45°, standard spring and autumn model): The annular diameter is of medium size, and the V-groove depth is moderate, suitable for mild climate conditions.

[0039] The angle adjustment range is 30-60°, which can be steplessly adjusted according to actual needs to adapt to different seasons, different light conditions and different plant growth stages.

[0040] Planting methods The installation method of the present invention includes the following steps: Step 1 – Cutting the binding tape: Measure the circumference of the trunk 1, mark the cutting length (trunk circumference + 20-30cm allowance) on the binding tape 2, and cut the binding tape 2.

[0041] Step 2 – Secure the umbrella ribs and binding straps: Wrap the binding straps 2 around the trunk 1, overlapping the two ends. Insert the lower ends of the insertion sections 31 of each umbrella rib 3 into the slots 21 on the outer periphery of the binding straps 2 in sequence to secure them. Use wire to wrap and twist or pull the one-way cable ties to tighten and lock them in place, thus securing the binding straps 2 to the trunk 1.

[0042] Step 4 – Erect the umbrella ribs: Flip all the support sections 32 of the umbrella ribs 3 upward around the hinge axis 33 and erect them.

[0043] Step 5 – Inserting the ring tie: Insert bidirectional cable ties into the wire holes 34 at each height of each support section 32. Connect the two-way cable ties end to end to form a ring. Adjust the length of each ring of bidirectional cable ties according to the target unfolding angle.

[0044] Step 6 – Laying the flexible planting bag: Lay the flexible planting bag 5 inside the support section 32, fold the upper edge over to wrap around the top of the support section 32 and clamp it tightly, and fold the bottom upward to cover the trunk 1.

[0045] Step 7 – Filling the substrate and planting: Fill the V-shaped planting space with pine bark substrate 7, and plant the Dendrobium officinale seedlings 8 in substrate 7 (3-5 seedlings per clump, spaced 10-15cm apart).

[0046] Maintenance and Harvesting During routine maintenance, regularly check the fixing status of the cable ties 2 and re-fix them if they are loose; regularly check whether the locking buckles 41 of the two-way cable ties are secure; check whether the flexible planting bag 5 is damaged and replace it in time if it is damaged.

[0047] When harvesting Dendrobium officinale, the ring diameter can be enlarged by pulling the bidirectional tie, which expands the support section 32 and makes the V-groove shallower, making it easier to operate and harvest. After harvesting, the bidirectional tie can be readjusted to the target angle to continue planting without disassembling the entire device.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
