Method for preparing compound submerged plant turf

Abstract

The invention discloses a method for preparing compound submerged plant turf; a degradable plastic grille web is adopted, and the method comprises the steps: 1) after the degradable plastic grille webis laid flatly, each grid is filled with sand and nutrient substances; 2) water is sprinkled to soak the degradable plastic grille web into water with the depth of 0.3 m; 3) vallisneria spiralls seeds are evenly spread to the upper surface of the grille web, and 2-3 months later, the water is emptied after vallisneria spiralls grows to 10-15 cm; 4) after sun-curing, since fine sand does not haveadhesive force, the degradable plastic grille web is gently lifted; and 5) ecological grids are placed in black and stinky river ways or landscape water bodies that need to be treated. According to the method for preparing the compound submerged plant turf, the turf cultivation process is simple and easy to operate and can be used for large-scale production, the produced turf is easy to transportand the survival rate is ensured. During construction, the turf is directly laid on the water bottom and is fixed, the difficulty of construction is reduced and the construction steps are simplified.

Description

technical field [0001] The invention relates to the fields of water environment ecological restoration and landscape water body construction, in particular to a method for making composite submerged plant turf. Background technique [0002] Eutrophication of water body is the response of aquatic organisms to the increase of nutrient concentration in water body and its change process. In the later stage, phenomena such as "algal bloom" and water body hypoxia usually occur, which is one of the main problems in the current water environment (Carpenter, 2005). Eutrophication causes algae to proliferate in large numbers, leading to a decrease in the transparency of the water body, a serious consumption of dissolved oxygen, and deterioration of the water quality, thereby damaging the ecosystem and functions of the water body and bringing losses to water utilization. A survey of water body eutrophication by the United Nations Environment Program (UNEP) shows that 30% to 40% of lake...

Problems solved by technology

Although these single species of turf can improve planting efficiency, they still cannot meet the actual planting needs. The most important thing for submerged phytoremediation is to build a relatively complex submerged plant ecosystem and maintain species diversity. Different aquatic plants need to be Clusters are fused together, instead of different clusters living within their own range, there is no intersection between clusters, because complex community structures are more stable and more resistant to external disturbances
