Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lake management, in particular to a management system for algal lakes. BACKGROUND

[0002] A well-functioning freshwater ecosystem is of great significance to environmental construction and building, one of which is caused by the proliferation of algae, such as cyanobacteria, leading to the abandonment or change of the environmental regulation function of the lake, which is mainly caused by high concentration of nutrients in the lake water, lack of supply chain, environmental pollution and other factors. Long-term pollution not only aggravates water pollution, but also deposits pollutants in the sediment. Even when the external pollution source is controlled, the sediment will act as an internal source of water pollution and release pollutants into the water, directly affecting the water quality.

[0003] There are several methods for lake management, generally divided into chemical method, physical dredging method and biological method, among which the chemical method will retain residues and have potential toxic effects;

[0004] The physical dredging method inevitably produces sediment particles suspended in the water and releases pollutants, causing secondary pollution, and consumes a lot of energy;

[0005] And the biological method can be treated by introducing plants, which not only consumes less energy, but also can enrich carbon dioxide, fix nitrogen and release oxygen during plant growth to form a low-carbon consumption management method.

[0006] By introducing submerged plants, the lake environment can be effectively changed and gradually transformed from an algal lake to a grassy lake. In practical application, it is found that simple planting of submerged plants can improve in the early stage, but as the depth of algal sediment degrades, the growth and development of submerged plants will be inhibited, thereby reducing the improvement effect.

[0007] Nigroa is a common submerged plant, which has the characteristics of perennial, can be used for a long time after planting, and has seed, bud, and different stages of planting methods such as adult plants, but the germination rate of seeds is not easy to control, and the root development of adult plants is slow, which is not conducive to root planting. The development of black algae bud is fast, which is conducive to the growth of black algae root system and can ensure the survival rate. However, manual underwater planting of black algae bud is not convenient, which increases the difficulty in the planting process, and because the upper sediment is loose or the sediment in the area is thin, the black algae bud is easy to float upwards and reduce the survival rate. Therefore, in order to improve the management effect, one of the ways is to improve the survival rate of black algae planting.

[0008] Therefore, we propose a management system for algal lakes. SUMMARY

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] When the black algae buds are planted, the black algae buds are buried in the soil in the object loading cavity, at this time, the second supporting plate 2 is attached and installed on the upper side of the first supporting plate 1, the rubber sheet 5 covers the upper end of the planting part 3, at this time, the first supporting plate 1 and the second supporting plate 2 attached together are placed in water, the black algae buds grow in the object loading cavity, the roots of the black algae buds grow in the object loading cavity, and the stems and leaves of the black algae buds grow upwards and push away the rubber sheet 5, so that the black algae can be planted.

[0033] As Figures 5-8As shown, in order to facilitate the growth of black algae, there is a gap between the two adjacent splicing rods 302 for the plant roots to grow outward, and the inside of the loading cavity is paved with a degradable pad 6, for example, a paper material, which is closely attached to the inner wall of the loading cavity. After the pad 6 is paved inside the loading cavity, when the planting piece 3 is immersed in water, the black algae sprouts during germination, and the pad 6 plays a protective role for the soil in the loading cavity, avoiding the soil being washed away by the water flow, reducing the sprouting rate of black algae sprouts, and after the pad 6 is immersed in water for a long time, the pad 6 can be degraded after a period of time or the black algae roots will pierce the pad 6 and grow out from the gap, which is beneficial to the black algae roots to absorb more nutrients and facilitate the growth of black algae.

[0034] And a plurality of counterweight rods 19 are arranged on the upper side of the second support plate 2, which increase the weight of the first support plate 1 and the second support plate 2, so that the first support plate 1 and the second support plate 2 can resist a certain intensity of water flow impact. The lower ends of the plurality of splicing rods 302 are gathered and spliced into a conical shape, and the arrangement of the counterweight rods 19 also facilitates the insertion of the bottom of the planting piece 3 into the bottom mud. At this time, the soil in the loading cavity is in contact and fusion with the bottom mud through the gap, increasing the root space of the black algae roots.

[0035] As shown in the figure, Figure 7 In order to further ensure the stability of the growth of black algae plants, the side wall of the splicing rod 302 is arranged in a toothed structure. When the black algae roots grow out from the gap, part of the black algae roots will be stuck in the teeth, which can stably make the roots grow inside the loading cavity, avoid the roots from moving around, and facilitate the growth of black algae plants.

During the growth of black algae, when the black algae stems and leaves lift the rubber sheet 5 and grow outward, the black algae stems and leaves intersect with the blocking rods 7. As the black algae stems and leaves continue to grow, the amount of mutual intersection between the black algae stems and leaves and the blocking rods 7 increases. At this time, the blocking rods 7 will hook the black algae stems and leaves, avoiding the black algae from separating from the planting piece 3, and the arrangement of the hooks 8 can make the blocking rods 7 more stably hook the black algae stems and leaves, ensuring the stability of the growth of black algae plants.
