Description

A planting device for submerged plants

technical field

The invention relates to the field of ecological restoration of water bodies, in particular to a device for planting submerged plants and a corresponding method.

Background technique

Restoring submerged plants is the key to ecological restoration of water bodies. Submerged plants are an important part of the water ecosystem, which can provide foraging, spawning and fattening habitats for fish and shelter for zooplankton. ecological niche and improve its habitat, which is beneficial to improve the biodiversity and stability of the ecosystem. In addition, submerged plants can absorb nutrients such as nitrogen and phosphorus in the water body, fix the sediment and inhibit the release of endogenous pollutants in the sediment, and at the same time inhibit the growth of cyanobacteria and other harmful organisms through niche competition, which is beneficial to controlling the eutrophication of the water body and purifying the water quality. It is of great value to improve water ecology.

Among the existing planting methods of submerged plants, the first is to use artificial planting. In the shallow water range, the operators directly cut the cuttings by hand in the water body; in the case of a slightly deeper water level, the operators generally use a bamboo pole or wood with a fork. The rod is used as a tool. When working, the operator uses a fork to fork the stem of the plant and fork it into the water. This method consumes a lot of labor costs and is time-consuming and labor-intensive. The second is the throwing method, which directly throws submerged plant seeds or seedlings into water or throws them in agar or non-woven fabrics. The latter is expected to carry submerged plants to the bottom through attachments, such as a method for rapidly cultivating and transplanting submerged plants disclosed in Patent Application No. 201710748656.5, using agar to fix, non-woven wrapping submerged plants into water bodies for planting, no The woven fabric gradually degrades and disappears with the growth of submerged plants, and the agar finally diffuses into the water body. This method is conducive to the submerged plants sinking to the bottom and provides certain nutrients for the growth of the submerged plants in the early stage. However, among the selected materials, the dissolution of the agar needs to be above 40 ° C, which is basically difficult to achieve in the underwater environment. The degradation of woven fabrics takes more than several months, and at the same time, it needs to consume the dissolved oxygen in the water body, which creates an unfavorable environment for improving the water body ecology. The third is to build some planting devices. For example, patent application number: 201720529945.1 discloses a submerged plant floating island with adjustable depth. Under the action of the pulling mechanism, the position of the planting box can be automatically adjusted according to the fluctuation of the water body, and the phenomenon of floating away of the planting box can be avoided. Another example is the patent application number: 201420563098.7, which discloses a submerged plant planting device. In this method, a positioning column is arranged on a river channel, a gabion is constructed in the positioning structure, and a submerged plant is planted on the gabion for fixing. However, these methods all have the problem of equipment recycling. After the sleeping plants are restored, the entire planting device must be manually recycled. At the same time, during the construction process, it will inevitably bring new pollution to the water environment. In addition, in the current submerged plant restoration projects, less attention is paid to the post-planting stage. During this period, due to the disturbance of wind and waves and organisms in the water environment, there is a risk that the sediments will rise and spread into the water, and the pollutants brought by them will cause harm to the growth of submerged plants.

SUMMARY OF THE INVENTION

In order to make up for the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a planting device for submerged plants, which uses bentonite and zeolite particles to press and form soil molds, carries submerged plants, and puts them into a target water body for planting.

The technical solution of the present invention includes the following steps:

1. Mix the bentonite and zeolite particles with tap water, and use the good plasticity of the bentonite to fully mix and stir to obtain the raw materials for the soil mold.

2. Fill the raw materials into the soil mold bottom plate mold and the pillar mold that have been made respectively. The bottom plate is designed as a triangle with three corners chamfered, a groove is set in the center, and a hole is opened near each corner, and each pillar is close to One end is provided with a card slot, which is taken out after pressing and molding, and dried for later use.

3. Use the holes of the bottom plate and the slots of the pillars to assemble a complete triangular pyramid soil mold. Wrap the roots of submerged plants with dry sphagnum moss and place them in the central groove of the floor, and tie them to a pillar of the soil mold.

4. Put the entire planting device into the target water body for planting.

Preferably, sodium bentonite is used as bentonite, and zeolite particles are used in a size of 20-40 mesh.

Preferably, the mass mixing ratio of bentonite, zeolite particles and water is 4:1:4.

The beneficial effects possessed by the present invention are as follows:

1. The overall mechanical structure of the triangular pyramid soil model made is stable. After carrying submerged plants, it is directly put into the target water body, which is convenient for planting and easy to sink to the bottom, which greatly reduces the risk of being washed away by unfavorable conditions such as water flow and improves planting efficiency. .

2. Use dry sphagnum moss to wrap the roots of submerged plants and tie them to the soil mold pillars. After sinking to the bottom, the dry sphagnum moss absorbs water as a good medium for the initial growth of submerged plants, and the survival rate at the early stage of planting can be improved.

3. Within a few days after the soil mold sinks to the bottom, it can absorb water, swell and crack, and collapse into a layer of soil cover, without the need to deal with subsequent recycling problems, saving a lot of work.

4. A layer of soil covering layer formed after the soil mold is cracked isolates the sediment and water body through physical isolation. At the same time, the zeolite particles contained in it rely on its huge inner cavity specific surface area and its own negative charge. It can adsorb organic pollutants and heavy metal ions in the sediment, and avoid the pollution caused by the pollutants in the sediment entering the water body due to disturbance.

5. The materials used in the whole planting device are simple and easy to obtain and will not cause secondary pollution to the environment. At the same time, the design is reasonable, the overall structure and operation process are simple, and the production cost is low, which is convenient for large-scale production.

Detailed ways

Below by embodiment, and in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

Mix the sodium bentonite with high plasticity and strong cohesiveness with the zeolite particles of 20-40 mesh in a mass ratio of 4:1, and gradually add tap water with the same quality as the bentonite and stir continuously. After complete homogenization, fill the prepared birch earth mold base mold and pillar mold respectively, apply pressure on the top, and take out and dry after molding. As shown in Figure 1, the bottom plate is designed as a triangle with three corners chamfered, with a circular groove in the center and a hole near each corner. As shown in Figure 2, the pillars are designed as oblique rectangular parallelepipeds, each pillar is provided with a slot near one end, and a part of the two corners is cut off at the top. Pass the pillars through the holes of the bottom plate and clamp them with the card slots. The three pillars are operated in the same way, the tops are close together, and the whole is assembled into a triangular pyramid soil mold.

Wrap the roots of the submerged plant to be planted into a spherical shape with dry sphagnum moss, place it in the groove in the center of the bottom plate, and tie it to a pillar of the soil mold, as shown in Figure 3. According to this method, batch production is performed in sequence, and the whole planting device is put into the target water body. After the soil mold is loaded with submerged plants and sinks to the bottom, the dry sphagnum moss absorbs water and becomes a good medium for the initial growth of submerged plants. After a few days, the soil mold broke down and collapsed into a layer of soil covering, covering the roots of submerged plants, and at the same time isolating the sediment sediment and the water environment, preventing the release of pollutants in the sediment into the water body.
