Description

Technical Field

[0001] This utility model relates to the field of submerged plant technology, and in particular to an auxiliary device for the establishment and growth of submerged plants. Background Technology

[0002] Submerged plants are large aquatic plants that live entirely submerged in the water column. They maintain the stability of clear water bodies through various direct (adsorption of nutrients such as nitrogen and phosphorus, inhibition of sediment resuspension, and inhibition of algae growth) and indirect (providing habitats and food sources for aquatic animals) mechanisms, and their importance to the restoration of aquatic ecosystems is widely recognized. Currently, the restoration needs for submerged vegetation in aquatic ecological restoration are more focused on aquatic environments where dewatering is not feasible. Therefore, the main method used is to plant plants by submerging them in water with a soil ball. One method involves wrapping the seedlings with a soil ball: using low-pollution topsoil to wrap the roots of the seedlings, and then wrapping them with biodegradable non-woven fabric to improve the stability of the seedlings. However, in this method, the soil ball wrapped around the roots can compress and damage the seedlings. Another method involves wrapping the roots of the seedlings with gravel and mesh: this reduces the compression damage to the seedlings, but the roots lack a substrate for initial growth, and the sharp edges of the gravel can cause friction damage to the plants when disturbed.

[0003] Therefore, all of the above planting methods will damage the propagation seedlings to varying degrees, resulting in a low survival rate. Furthermore, the propagation seedlings grow at the bottom of the water and receive poor light conditions, which affects their growth, especially in open water bodies with poor light conditions.

[0042] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 The orientation is used as a reference.

[0043] Example 1

[0044] See Figure 1 The present invention provides an auxiliary device for the planting and growth of submerged plants, comprising a net bag 1, a traction rope 2, and a counterweight 3.

[0045] Net bag 1 has an opening and is capable of enclosing a submerged plant propagation seedling A. The first end of a guide rope 2 is tied to and tightens the opening of net bag 1 after enclosing the propagation seedling A. The second end of the guide rope 2 is connected to a counterweight 3, the weight of which is greater than the total weight of the propagation seedling A and net bag 1. In use, the counterweight 3 can sink to the bottom of the water, allowing net bag 1 and the propagation seedling A inside to float in the water, enabling the propagation seedling A to grow in a suspended state. It should be noted that the propagation seedling A includes broken branches, seedlings, or a mixture of broken branches and seedlings from submerged plants, and each net bag 1 encloses one or more propagation seedlings A. Broken branches refer to branches cut from mature plants, and seedlings refer to plants with complete root, stem, and leaf morphology; both broken branches and seedlings can continue to grow.

[0046] In this embodiment, the propagation seedling A is wrapped in a mesh bag 1, preventing it from being squeezed or scratched, thus ensuring a high survival rate. A counterweight 3 and a traction rope 2 suspend the propagation seedling A in the water, providing sufficient light to ensure normal photosynthetic intensity and promoting rapid growth and propagation. The counterweight 3 ensures the seedling A remains stable on the bottom, preventing displacement due to waves and high-velocity water flow, maintaining a stable distribution. Therefore, this submerged plant planting and growth assistance device improves the resistance of the wrapped propagation seedling A to low light stress and water disturbance, promoting its growth and achieving the goal of aquatic ecological restoration. It is particularly suitable for the ecological restoration of water bodies with strong disturbance and poor light conditions. Furthermore, this embodiment has a simple structure, low cost, and is easy to manufacture.

[0047] Furthermore, the method of using this submerged plant planting and growth assistance device is as follows:

[0048] S1: Preparation of submerged plant propagation seedlings A: Use submerged plants suitable for planting in net bag 1 and capable of suspended growth, including hornwort and whorled hydrangea. Select robust and well-shaped branches with a length of 30-60cm, divide them into seedling clumps according to a weight of 100-300g, and make propagation seedlings A.

[0049] S2: Preparation of net bag 1 and counterweight 3: Cut a square net according to the size of the seedling A to serve as net bag 1 for the seedling A. Wrap the seedling A with net bag 1, gather the four corners of net bag 1 together, tie the first end of the guide rope 2 to tighten the opening of net bag 1, and tie the other end to counterweight 3.

[0050] S3: Planting of submerged plant seedlings: Plant seedlings in the target water area at a density of 800-1200g per square meter. When planting, hold the counterweight 3 and gently throw it into the water to avoid damaging the propagation seedlings A by holding the net bag 1.

[0051] Preferably, the vertical distance between the top of the propagation seedling A suspended in the water and the water surface is less than 0.5m to ensure normal photosynthetic intensity of the plant. The specific vertical distance can be determined according to the water depth and wave height. This specified vertical distance refers to the vertical distance under waveless conditions.

[0052] Preferably, the traction rope 2 is made of hemp thread, which has a lower cost.

[0053] Preferably, the mesh bag 1 is a biodegradable mesh bag 1, which is friendly to the aquatic environment.

[0054] Preferably, the weight of counterweight 3 is 1.5-2 times the weight of the propagation seedling A to resist wind and wave disturbance in the water and prevent the propagation seedling A from shifting. The specific weight can be selected according to the intensity of wind and wave disturbance in the target water area.

[0055] Example 2

[0056] See Figure 2-4 Based on Example 1, this embodiment provides a submerged plant planting and growth assistance device, which also includes a chassis 4 and a binding component 5.

[0057] The opening of the net bag 1 can fit over the perimeter of the base plate 4 and be secured to the perimeter of the base plate 4 by the binding device 5. The net bag 1 and the base plate 4 form a space that can enclose the seedling A, thereby expanding the space for enclosing the seedling A and promoting its growth. The binding device 5 can tie the first end of the guide rope 2 to the perimeter of the base plate 4 to secure the guide rope 2.

[0058] Optionally, the binding element 5 is a cable tie. The binding element 5 can tighten the bottom opening of the net bag 1 and tie it to the surrounding wall of the chassis 4 at the same time as the traction rope 2, so as to facilitate binding and improve the binding strength and stability, and prevent the net bag 1 and the traction rope 2 from being loosened by water waves, causing the seedling A to escape from the net bag 1.

[0059] More preferably, an annular groove is provided on the peripheral wall of the chassis 4, and the binding member 5 can bind the opening of the net bag 1 and the first end of the traction rope 2 into the annular groove to improve the binding strength of the net bag 1 and the traction rope 2.

[0060] More preferably, a slot is provided at one end of the chassis 4 for inserting the seedling A, so as to help support the seedling A and improve its ability to resist the disturbance of wind, waves and high-velocity water flow, and promote its rapid growth.

[0061] More preferably, the chassis 4 is a biodegradable plastic chassis 4, which is environmentally friendly.

[0062] Preferably, a sleeve 6 is fitted onto the traction rope 2 to improve the traction rope 2's ability to resist the disturbance of wind and waves in the water, maintain the stability of the position of the propagation seedling A, and help the propagation seedling A grow.

[0063] Optionally, sleeve 6 can be made of biodegradable plastic, which is environmentally friendly to aquatic environments.

[0064] More preferably, there are multiple traction ropes 2 and sleeves 6, with multiple sleeves 6 being fitted onto the traction rope 2 in a one-to-one correspondence. This further enhances the traction rope 2's ability to resist the strength of water waves and improves the stability of the location of the seedling A, so that the seedling A can be maintained in the water area that needs to be restored, thereby improving the water body restoration effect.

[0065] Preferably, the counterweight 3 is made of sand wrapped in biodegradable nonwoven fabric, which is low in cost, easy to prepare, and environmentally friendly.

[0066] Preferably, a drum 7 is fixedly installed on the counterweight 3, the second end of the traction rope 2 is wound around the drum 7, and a lock 8 that can be opened and closed is fitted on the free end of the second end of the traction rope 2 and the body of the traction rope 2.

[0067] When the latch 8 is opened, the free end of the traction rope 2 can move up and down relative to the body of the traction rope 2 to adjust the vertical distance between the counterweight 3 and the base plate 4, thereby adjusting the depth of the seedling A in the water so as to meet the light requirements of different types of seedling A.

[0068] When the latch 8 is closed, the free end of the traction rope 2 can be locked onto the body of the traction rope 2.

[0069] Optionally, latch 8 is a shackle.

[0070] The locking mechanism 8 includes an open connecting ring, a baffle, and a nut. Both ends of the open end of the connecting ring are threaded, allowing it to simultaneously encircle both the free end of the traction rope 2 and the body of the traction rope 2. Two through holes on the baffle allow the two ends of the connecting ring to be inserted, enabling the connecting ring and baffle to cover both the free end of the traction rope 2 and the peripheral wall of the traction rope 2 body. Nuts, screwed onto the two ends of the connecting ring that extend beyond the baffle, abut against the baffle to close the locking mechanism 8. To open the locking mechanism 8, the nut is removed, loosening the baffle and connecting ring to allow the free end of the traction rope 2 to move up and down relative to the traction rope 2 body.

[0071] Preferably, the roll 7 includes two parallel support plates 72 and a shaft 71 connected to the two support plates 72 at both ends. The two support plates 72 extend horizontally and away from each other to form connecting seats 73 with through holes. A sewing thread can be threaded through the through holes of the connecting seats 73 to sew and fix the roll 7 to the non-woven fabric of the counterweight 3, thus facilitating the fixing of the connecting seats to the roll 7. This method is easy to manufacture and has a low cost.

[0072] Furthermore, to better demonstrate the repair effect of this embodiment, the following is a comparative experiment comparing this embodiment with one using counterweight 3 directly tied to the propagation seedling A:

The counterweight 3 is made of dry yellow sand wrapped in biodegradable non-woven fabric. Wrap the propagation seedling A in net bag 1, and use the first end of the guide rope 2 to tie and tighten the opening of net bag 1, and connect the second end to the counterweight 3. The weight of the counterweight 3 is twice the weight of the propagation seedling A.

[0076] A3: Planting of Propagation Seedling A: Plant propagation seedling A at a density of 1200g per square meter in the target water area. When planting, hold the counterweight block 3 and gently toss it into the water.
