Combined ecological floating bed for water planting plants and flowers

Abstract

The invention relates to a combined ecological floating bed for water planting plants and flowers, which is characterized by comprising one or more ecological floating bed units which are combined, interconnected and fixed to form the combined ecological floating bed for the water planting plants and flowers with various patterns; the ecological floating bed unit comprises a planting basket, a floating bed framework and a foam piece, wherein the planting basket is placed in a planting basket placing port of the floating bed framework; the foam piece is sleeved in a cavity of the floating bed framework; and a plurality of ecological floating bed units are connected to form a large-area water planing plant-flower garden or a fixed green ecological floating island. The ecological floating bed has the advantages of unique structure, convenient manufacture and low cost, can effectively reduce the content of phosphorus and nitrogen-like eutrophic salts polluting the water and COD and BOD, promote the water quality from VI class to III class and beautify the environment, and can be widely applied to the water surfaces of extensive polluted rivers and lakes.

Description

technical field [0001] The invention relates to the field of ecological agricultural environmental engineering, in particular to a combined ecological floating bed for planting plants and flowers in water bodies. Background technique [0002] my country is a country with many lakes. With the development of social economy and the improvement of people's living standards, the discharge of industrial and agricultural production and domestic sewage exceeds the capacity of the lake water system. "Every lake will be destroyed" seems to be an irresistible force trend. The eutrophication of lakes, reservoirs, and rivers is serious, and cyanobacteria "blooms" appear frequently, and the area spreads year by year, and the duration increases year by year. Taihu Lake, Dianchi Lake, Chaohu Lake, and Hongze Lake all have "water blooms", and even flowing rivers, such as the largest tributary of the Yangtze River-the Hankou section of the lower reaches of the Han River, also have "water bloo...

AI Technical Summary

Problems solved by technology

[0005] At present, the method of using "constructed wetlands" to establish aquatic ecosystems requires plants to be planted in underwater soil, so it is limited to the shore or shallow lakes, and plants cannot grow in deep water

Using the buoyancy of the foam board, directly punch holes on the foam board to make an ecological floating bed, and plant plants suitable for aquatic growth on it. This method solves the problem of planting aquatic plants in deep water, but the foam board has almost no mechanical strength. It is easy to break and float on the water surface after breaking, causing secondary pollution

Use bamboo, wood and other materials with a specific gravity less than 1 to make an ecological floating bed, and use the buoyancy of the material itself to make aquatic plants grow on the water surface. The disadvantage of this method is that bamboo and wood are easy to rot after soaking in water for a long time, which affects the ecological floating bed. The structural strength of the ecological floating bed is limited, and the decay of the bamboo itself will also cause certain pollution to the water environment.
