Problems solved by technology

[0005] For a long time, the cost of planting submerged vegetation has remained high. The main influencing factor is that the natural conditions of large lakes are complex. Strong winds, high waves, rapid currents, mixed water, and algae damage have all made the restoration cost of submerged vegetation continue to rise. Severely limited the promotion of submerged vegetation throughout the lake waters, especially in the northern part of the large lake, which is significantly affected by the summer monsoon

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] The present invention relates to a simple cut-off planting method for submerged plants in a lake. In the open water area of ​​the lake, a large-area cyanobacteria protection area is established, and a planting area of ​​more than 0.25 square kilometers is formed by floating enclosures to prevent the floating cyanobacteria outside the planting area from being damaged. Invasion of submerged vegetation in planting areas. Although the algae-blocking fence adopted outside the planting area does not block waves and wind, it blocks the floating cyanobacteria from outside and cuts off the rushing lake current. Compared with wind-blocking and wave-blocking facilities, the cost is greatly reduced. Said planting area can be expanded infinitely to extend across the entire body of water, allowing all water areas to be improved. However, the cut-off breeding area surrounded by ha...

Abstract

The invention relates to an easy planting method for lake submerged plant through water interception, which proposes that lake mud containing corresponding materials capable of helping submerged plant to propagate and grow, such as roots, stems, seeds and buds are used for quickly and easily plant the lake submerged plant in a planting area without underflow. In the easy planting method, a large planting area of more than 0.25 square kilometers and a small water interception area of 2500 to 10,000 square kilometers are surrounded by floating enclosures with full height or half height so as to prevent blue algae out of the planting areas and wind-driven lake current from damaging the plant in the planting areas; the method of dredging along a strip-shaped area biennially is utilized, the lake mud in the areas for helping the submerged plant to propagate and grow is dredged to obtain the materials capable of helping the submerged plant to propagate and grow, such as roots, stems, seeds, buds and the like, and the mud is uniformly thrown into the planting areas as much as possible. The planting method of the present invention has simple and quick effect, low cost and high efficiency, the submerged plant can recover propagation and growth easily and quickly, and the problem that present technique for recovering the propagation and growth of the submerged plant in free lake water areas has complexity, high cost and difficulty in generalization is solved.

Description

technical field [0001] The invention relates to a simple and cut-off planting method for lake submerged plants, which utilizes local species to simply and quickly plant and restore submerged vegetation, and belongs to the technical field of resources and environment. Background technique [0002] In recent years, the hazards of cyanobacterial blooms in large diving lakes represented by Taihu Lake in my country have become increasingly serious, which has brought serious impacts on social economy and people's lives. Studies have shown that under the same environmental background, algae lakes and grass lakes can be converted to each other. Converting the existing algae lakes with cyanobacteria as the main primary productivity to grass lakes with aquatic plants as the main primary productivity is an important way to improve the quality of lakes. Ecological environment, an ideal way to control the harm of blue-green algae. [0003] For large lakes, restricted by conditions such ...
