Soilless Lawn Ecological Landscape Floating Island

Abstract

The invention discloses a soilless-lawn ecological landscape floating island. Each soilless lawn is made in two stand specifications, namely 1m*1m and 1m*2m. The soilless lawns are respectively used according to engineering requirements. A production process includes: material for floating each lawn is disposed below the soilless lawn which is made into a standard floating island module; on construction site, the adjacent floating island modules are tied with nylon ropes according to the engineering required area, and the required ecological landscape floating island is made; thus, construction on the engineering site is more convenient and faster. Factory production and standard production are truly achieved. The ecological landscape floating island made of soilless lawns of gramineous grasses is low in height, can withhold big wind, heavy rain and huge waves, and can be used under the conditions such as different water flows, different temperatures, and different eutrophication levels. The ecological landscape floating island has flat surface and sufficient floatage, and workers can use mowers to mow on the lawns during large-area use of the ecological landscape floating island.

Description

technical field [0001] The invention relates to a soilless lawn ecological landscape floating island, in particular to an ecological landscape floating island constructed by a soilless lawn for beautifying water body landscape and purifying polluted water body. Background technique [0002] Eutrophication of water bodies is a global water environment problem. There are more than 2,700 lakes in my country, with a total area of ​​91,000 km2. According to the survey data and domestic and foreign evaluation indicators of lake eutrophication, among the 37 typical major lakes in China, 55.8% are medium eutrophic and medium eutrophic, 14.7% are eutrophic, and 14.7% are heavy eutrophic. 8.8%. More than 90% of water pollution in China is caused by eutrophication caused by excessive N and P content in water bodies, while N and P are the most basic essential nutrients for plant growth. Ecological floating island technology uses floating materials as substrates or carriers to plant hi...

AI Technical Summary

Problems solved by technology

[0004] 1 The existing ecological floating island cultivation is not easy to carry out standardized promotion and application

Different lakes and rivers have different eutrophication levels, water flow, temperature, wind speed, water fluctuations, etc., which require corresponding floating island design combinations and floating island plant species, and it is difficult to formulate a unified standard for popularization and application.

[0005] 2. Existing ecological floating islands are difficult to implement mechanized operations

The ecological floating island is floating on the water surface, and the daily management is completed on the water surface. At present, most of its management operations are done manually, which is acceptable in small-scale experiments and demonstrations. If it is popularized in a large area, it needs to be harvested frequently and in a timely manner, and manual operation is required. cannot meet the needs and limit its development

[0006] 3. The construction period of the existing ecological floating island is long

From the current point of view, most ecological floating islands adopt the mode of on-site production and on-site planting, and the construction period of large-scale production is relatively long

[0007] 4. The existing ecological floating islands are difficult to survive the winter

[0008] 5. Most of the existing ecological floating islands use large-scale aquatic plants and aquatic vegetables, which are difficult to resist extreme winds, heavy rains and waves

[0009] 6. At present, the area of ​​ecological floating islands used at home and abroad is small, and most of them are used in small rivers and lakes. It is difficult to carry out ecological restoration on larger rivers and lakes. Now there is a need for large-scale ecological floating islands
