Submerged plant cultivation tank

Abstract

The invention provides a submerged plant cultivation tank. The submerged plant cultivation tank comprises a tank body of which the top is provided with an opening and a tank cover net (3) which is arranged at the opening of the top of the tank body. Compared with the submerged plant cultivation tank adopted by the prior art, the submerged plant cultivation tank has the advantages that: the opening of the top of the submerged plant cultivation tank is provided with the tank cover net; and mud is placed in the tank body during use, the submerged plant can pass through the tank cover net during growth, and the rhizome of the submerged plant is wound on the tank cover net, so that the submerged plant is fixed. The tank cover net has a good function of fixing the submerged plant, and can prevent the submerged plant in the cultivation tank from being washed away.

Description

technical field [0001] The invention relates to the technical field of water body pollution control, and more specifically relates to a submerged plant cultivation box for water body pollution control. Background technique [0002] The types of urban landscape water bodies mainly include rivers, lakes, reservoirs, park water systems, artificial canals and artificial lakes that flow through urban areas, and even the overall regional water systems of nature reserves and ecological zones. In recent years, the status of urban landscape water body in the city is getting higher and higher. At the same time, the eutrophication of urban landscape water body is becoming more and more serious, which seriously affects the natural environment around urban landscape water body and the living environment of residents. [0003] Due to its low cost, high environmental benefits and good restoration effect, bio-ecological restoration technology has gradually become a common means to control t...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned submerged plants have played an important role in the restoration of urban landscape water bodies, but most of the substrate environments of existing urban landscape water bodies are hard bottoms (such as cement bottoms, pebble bottoms, masonry bottoms, hard mud bottoms, etc.) , and the water body has a certain degree of fluidity, so submerged plants can hardly survive

In the era when silt dredging has always been considered as an important method and approach for the treatment of eutrophic water bodies, it is not acceptable to introduce a large amount of soil to cultivate submerged plants in the above-mentioned urban landscape water bodies, and secondly, the amount of engineering is large, especially in some Urban gardens with inconvenient transportation (such as the world cultural heritage - many gardens in Suzhou City) cannot be transported into the soil by engineering vehicles

People used to put a small amount of soil in the plastic frame to cultivate submerged plants for the treatment of water eutrophication, but the soil in the plastic frame was washed away quickly, and the submerged plants were washed away, making it difficult to restore Effect
