Description

Technical Field

[0001] This utility model relates to the field of Spartina alterniflora control technology, and more specifically, to an ecological control device for Spartina alterniflora. Background Technology

[0002] Spartina alterniflora, an invasive alien species, has caused severe damage to coastal wetland ecosystems in China since its introduction in the late 1970s due to its extremely strong reproductive and dispersal capabilities. Its rapid expansion has led to a decline in native biodiversity, the disappearance of large areas of mangroves, waterway blockages, impacts on fisheries production, and the degradation of coastal wetland ecosystems.

[0003] Currently, the main methods for controlling Spartina alterniflora are manual and mechanical removal, followed by suffocation with plastic film. While this method can control most of the Spartina alterniflora, it is not very efficient. Herbicides are more effective, but require large quantities and can cause environmental pollution.

[0004] The problem this application aims to solve is how to combine the two methods to reduce environmental pollution while improving the control efficiency of Spartina alterniflora. Utility Model Content

[0005] This invention provides an ecological control device for Spartina alterniflora to solve the contradiction between the low efficiency of existing Spartina alterniflora control and the serious environmental pollution.

[0006] According to one aspect of this utility model, an ecological control device for Spartina alterniflora is provided, comprising an insertion rod, a fixing rod, and a film covering roll. Two fixing rods are spaced apart. The insertion rod is installed at both ends of the fixing rod for fixing to the soil layer. The fixing rod has a circular cross-section with its outer edge recessed inward to form two circular receiving cavities. A flange is formed between the two receiving cavities. A film is wound onto the film covering roll and installed in each receiving cavity. The insertion rod is inserted into the soil, and the film covers the upper part of the Spartina alterniflora between the two fixing rods. The two free ends of the film are pressed into the soil for fixation.

[0007] Preferably, based on the above scheme, there are two film-coating rolls, and a first film layer and a second film layer are wound on the two film-coating rolls. The first film layer is a black light-blocking film, and the second film layer is disposed below the first film layer and close to the Spartina alterniflora side.

[0008] Based on the above scheme, the second coating layer is preferably made of plant fiber woven into an inhibitory film, and the inhibitory film is embedded with anti-rice agent.

[0009] Based on the above scheme, preferably, the anti-rice cleaner is embedded in the plant fibers in a granular form.

[0010] Preferably, based on the above scheme, the black light-blocking film is an airtight PVC film.

[0011] Preferably, based on the above scheme, the insertion rod is provided with an arc-shaped hook, and the open end of the hook faces the fixed rod.

[0012] This utility model discloses an ecological control device for Spartina alterniflora. By welding inserts to both ends of a fixed rod, the device can quickly fix the fixed rod to the soil. A first and second mulch layer are stored separately using mulch rolls, which are inserted into the storage cavity for easy transfer. The first mulch layer is opaque and airtight, which reduces the growth of Spartina alterniflora. The second mulch layer contains an anti-spartinacid agent. In the space between the first mulch layer and the soil, the airtightness and sunlight exposure cause the temperature to rise, resulting in water evaporation. The evaporated water vapor comes into contact with the second mulch layer, dissolves the anti-spartinacid agent, and acts on the Spartina alterniflora to achieve the purpose of weed control.

[0013] Compared with existing technologies, the Spartina alterniflora ecological control device of this utility model has a simple structure and is easy and quick to install and operate. It uses the interaction between high-temperature evaporation of water vapor and anti-spartina alterniflora agent embedded in the second film layer to effectively reduce the amount of herbicide used and reduce environmental pollution.

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] Please see Figure 1 and combined Figure 2 and Figure 3As shown, the present invention provides an ecological control device for Spartina alterniflora, comprising a pole 1, a fixing pole 2, and a film-covering roll 3. There are two fixing poles 2, which are spaced apart. The poles 1 are installed at both ends of the fixing poles 2 for fixing to the soil layer. It should be noted that there can be four or more poles 1. In actual use, the number can be set according to the length of the fixing poles 2. Preferably, a pole is set at an interval of about 1m.

[0023] In this invention, the fixing rod 2 has a circular cross-section, and the outer edge of the fixing rod 2 is recessed inward to form two circular storage cavities 22. A flange 21 is formed between the two storage cavities 22. In this invention, a film-coated roller 3 is installed in each of the two storage cavities 22. A film is wound on the two film-coated rollers 3. The ends of the other two film-coated rollers 3 are fixed to the film opposite to the film-coated roller 3.

[0024] When in use, insert the rod 1 into the soil, cover the upper part of Spartina alterniflora between the two fixing rods 2 with the film, and press the two free ends of the film into the soil to fix it.

[0025] In this invention, there are two film-coating rolls 3, and a first film layer 31 and a second film layer 32 are wound on the two film-coating rolls 3. The first film layer 31 is a black light-blocking film, and the second film is disposed under the first film layer and close to the side of Spartina alterniflora.

[0026] When using it, first, measure the Spartina alterniflora and compare the tidal water level. Then, take into account factors such as the treatment time, the amount of Spartina alterniflora submerged, and the equipment construction time when selecting the cutting equipment.

[0027] Before the Spartina alterniflora germinates and the seeds mature, in the Spartina alterniflora growing area at a higher elevation, an amphibious rotary tillage cutter can be used for cutting, which can be carried out at both high and low tides. The height of the basal stubble should be controlled at 1-3 cm. After cutting, the Spartina alterniflora should be salvaged and processed on land.

[0028] After cutting, the fixing rods 2 are pulled apart relative to each other according to the position of the base residue of Spartina alterniflora. The film on the two film rolls 3 inside the fixing rods 2 is fixed to one of the film rolls 3 and rolled on the other film roll 3. When subjected to external force, the film is relatively stretched and covers the base residue of Spartina alterniflora. In order to avoid the base residue of Spartina alterniflora from piercing the film, the height of the film is controlled to be 5-6 cm greater than the height of the base residue.

[0029] In this way, a relatively closed space can be formed between the basal stubble of Spartina alterniflora and the film. The first covering layer 31 of this invention is a black light-blocking film, and the black light-blocking film is an airtight PVC film. In this way, the black light-blocking not only absorbs external heat, causing the temperature inside the closed space to rise, but also prevents Spartina alterniflora from photosynthesizing and inhibits its growth. At the same time, when the temperature inside the closed space rises, the second covering layer 32 is an inhibitory film made of plant fiber warp and weft, and anti-spartinacid is embedded in the inhibitory film. Water vapor acts on the anti-spartinacid, causing it to be released into the closed space and quickly absorbed by Spartina alterniflora to achieve the purpose of rapid and efficient weed control. Among them, anti-spartinacid is a new pollution-free preparation developed by Beijing Forestry University. Its main component is 25% imidazole nicotinic acid aqueous solution. The inhibitory film made of plant fiber warp and weft is immersed in the second covering layer 32 and dried, so that the anti-spartinacid is embedded in the plant fiber.

[0030] In another preferred embodiment of this utility model, in order to ensure the sealing effect between the film and the base residue of Spartina alterniflora and to prevent light from entering from both ends and affecting its effect, a layer of film can be set around both ends of the film to ensure its weeding effect.

[0031] Furthermore, in order to improve the stability of the mulch and avoid the problem of the mulch being overturned by wind and waves, the insertion rod 1 of this utility model is provided with an arc-shaped hook 33. The open end of the hook 33 faces the fixed rod 2. When inserted inward, the outer arc-shaped hook 33 can be quickly inserted through arc-shaped friction. When pulled outward, the interaction between the hook and the soil can increase the resistance to pulling outward, thereby improving its resistance to wind and waves.

[0032] This utility model discloses an ecological control device for Spartina alterniflora. By welding the insertion rod 1 to both ends of the fixing rod 2, the device can quickly fix the fixing rod 2 to the soil. The first covering layer 31 and the second covering layer 32 are respectively housed by the covering roll 3. The covering roll 3 is inserted into the housing cavity 22 for easy transfer. The first covering layer 31 is opaque and airtight, which can reduce the growth of Spartina alterniflora. The second covering layer 32 is embedded with anti-spartina alterniflora agent. In the space formed between the first covering layer 31 and the soil, the temperature rises due to the airtightness and sunlight, causing water evaporation. The evaporated water vapor comes into contact with the second covering layer 32, and the anti-spartina alterniflora agent dissolves and acts on the Spartina alterniflora to achieve the purpose of weed control.

[0033] Compared with existing technologies, the Spartina alterniflora ecological control device of this utility model has a simple structure and is easy and quick to install and operate. It uses high-temperature evaporation of water vapor and the interaction between the anti-spartina alterniflora agent embedded in the second film layer 32 to effectively reduce the amount of herbicide used. At the same time, the anti-spartina alterniflora agent of this utility model is 25% imidazole nicotinic acid, which has low residue and can effectively reduce environmental pollution.

[0034] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
