[0002] Bamboo grows rapidly, and its rhizomes (root systems) have an extremely strong ability to spread underground, mainly manifested in their rapid lateral growth. Around buildings, bamboo root spread can damage foundations, underground pipelines, and other infrastructure; near farmland, bamboo roots can invade crops, competing for nutrients and growing space, affecting crop yields; in nature reserves, the uncontrolled spread of bamboo can disrupt the balance of the original ecosystem. Currently, although there are some methods to prevent plant root spread, such as using concrete walls, trenches, and irrigation for isolation, many suffer from high construction costs, complex installation of some fixed protective devices, and difficulty in adjusting or dismantling them according to actual needs. When the needs of the protected area change, these devices become unusable, resulting in resource waste. Therefore, developing an efficient and detachable bamboo root spread prevention device is of significant practical importance. Utility Model Content

[0033] The purpose of this utility model is to provide a bamboo rhizome prevention board and a bamboo rhizome prevention device to solve the problems existing in the prior art. It prevents bamboo rhizome from spreading by combining physical barriers and chemical root pruning, thereby protecting the growing space of underground plants or other crops.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figures 1-11 As shown, this utility model provides a bamboo rhizome prevention board, including a protective board 1, a chemical barrier layer 2 is provided on the side of the protective board 1 facing the bamboo rhizome, and the chemical barrier layer 2 is attached to the protective board 1.

[0037] Working principle:

[0038] The bamboo rhizome-preventing board is vertically installed underground, with its surface facing the tip of the bamboo rhizome. The protective board 1, made of rigid material, acts as a physical barrier to directly block the spread of bamboo rhizomes. The chemical barrier layer 2 is rich in substances that kill bamboo rhizome cells. When the tip of the bamboo rhizome comes into contact with the chemical barrier layer 2, it dies and stops growing, achieving a chemical root-pruning effect. Chemical root pruning refers to the technique of treating plant roots with chemical substances (such as hormones, acids, oxidants, or other chemical agents) to regulate their growth, morphology, or function. This invention utilizes the root-killing function of chemical root pruning. This invention prevents bamboo rhizome spread by combining physical barriers and chemical root pruning, protecting the underground planting space or the growing space of other crops. The chemical barrier layer 2 is positioned on the side of the protective board 1 facing the bamboo rhizome, allowing the bamboo rhizome to be chemically pruned first, directly killing it and preventing further growth. This achieves the best effect in preventing bamboo rhizome spread while also preventing the bamboo rhizome from directly impacting the protective board 1, extending the service life of the protective board 1.

[0039] When installing bamboo spread prevention boards, dig a trench at the designated location to place the boards. The trench depth should be slightly less than the vertical length of the boards when placed vertically. Then, place the boards vertically into the trench, backfill with soil, and compact it. The portion of the boards not buried in the soil will serve as a warning strip.

[0040] In one embodiment, the chemical barrier layer 2 is coated onto the surface of the protective plate 1.

[0041] In one embodiment, the chemical barrier layer 2 is a finished product, and the chemical barrier layer 2 is fixedly installed on the protective plate 1, with the chemical barrier layer 2 and the opposite surface of the protective plate 1 being in contact.

[0042] In one embodiment, the protective plate 1 is a flat plate structure.

[0043] In one embodiment, the protective plate 1 is a corrugated plate, and the corrugated structure of the protective plate 1 is arranged in a horizontal direction. When the chemical barrier layer 2 fails, the tip of the bamboo whip will directly contact and squeeze the protective plate 1. The corrugated plate has a stronger mechanical force resistance and can reduce the destructive effect of the bamboo whip tip on the protective plate 1.

[0044] In one embodiment, the bottom of the protective plate 1 is provided with a pin 3, the insertion end of which has a pointed structure. When installing the anti-bamboo spread plate, the pin 3 can be directly inserted into the ground for fixation, and the protective plate 1 can be kept stable without the need for external force during the backfilling and compaction steps. It is understood that the shape of the pointed structure is a shape that ensures that the pin 3 is firmly inserted into the ground, including but not limited to cone, thatch-shaped, arrow-shaped, etc.

[0045] In one embodiment, the pin 3 and the protective plate 1 are an integral structure.

[0046] In one embodiment, the protective plate 1 is a high-density polyethylene (HDPE) plate, with a thickness of not less than 2 mm and a height of not less than 80 cm. HDPE is inexpensive, strong, and chemically stable, and will not cause soil pollution when buried underground. It is understood that the protective plate 1 can also be made of other inexpensive, strong, and chemically stable materials.

[0047] In one embodiment, the chemical barrier layer 2 contains a copper compound. Copper ions or copper elements can interfere with root cell division and elongation, leading to root cutinization or changes in growth direction, while high concentrations of copper ions or copper elements can directly kill plant roots.

[0048] In one embodiment, the chemical barrier layer 2 includes a first membrane 201, a first modified bitumen layer 202, a copper compound layer 203, a second modified bitumen layer 204, and a second membrane 205 sequentially bonded together, with either the first membrane 201 or the second membrane 205 bonded to the protective plate 1. When the tip of the bamboo rhizome pierces the first membrane 201 (second membrane 205) and the first modified bitumen layer 202 (second modified bitumen layer 204), it comes into contact with the copper compound layer 203. The copper ions in the copper compound layer 203 then interfere with the growth of the bamboo rhizome or directly kill it, thus providing a chemical barrier. The first membrane 201 (second membrane 205) and the first modified bitumen layer 202 (second modified bitumen layer 204) isolate the copper compound layer 203 from the soil, preventing copper ions from directly penetrating the soil. It is understood that the thicknesses of the first membrane 201, the first modified bitumen layer 202, the copper compound layer 203, the second modified bitumen layer 204, and the second membrane 205 can be adjusted according to actual needs.

[0049] In one embodiment, the copper compound layer 203 comprises one or more combinations of copper sulfate, copper complex, copper chloride, and copper-based nanoparticles.

[0050] Example 2

[0051] like Figures 1-11 As shown, this utility model also provides a device to prevent the spread of bamboo shoots, including a connector 4 for connecting the bamboo shoot-prevention plates and the aforementioned bamboo shoot-prevention plates. The first end of the connector 4 is located on the side of one bamboo shoot-prevention plate, and the second end of the connector 4 is located on the side of another bamboo shoot-prevention plate. Multiple bamboo shoot-prevention plates are connected sequentially to form the device, which can cover a larger area. Preferably, the connector 4 is a waterproof hinge, and adjacent bamboo shoot-prevention plates can adjust their angle to match the terrain.

[0052] In one embodiment, the connector 4 is a column connector 41. The column connector 41 includes two connected connecting plates, which are perpendicular to each other. The bottom of the column connector 41 has a pointed structure, and the side of the anti-bamboo spread plate is installed on the connecting plate and located inside the column connector 41. When it is necessary to connect the anti-bamboo spread plates into a closed protective area, the column connector 41 can be used to seal the corner positions of the area. The inside of the column connector 41 is the area corresponding to the 90-degree angle formed by the two connecting plates. Two adjacent anti-bamboo spread plates installed inside the column connector 41 can form a corner structure, achieving a sealing effect. Preferably, the column connector 41 is made of cast iron, and the anti-bamboo spread plate is fixed to the column connector 41 by bolts.

[0053] In one embodiment, connector 4 is a long strip plate with a pointed bottom, which is used to connect adjacent anti-spreading bamboo strip plates.
