A method for making composite submerged plant turf

Abstract

The invention discloses a method for making composite submerged plant turf. The method comprises the following steps of firstly, preparing a growth substrate for submerged plant turf, wherein lake mud and unpolluted soil and silver sand are treated; secondly, preparing a turf culture mould and a plant growth frame structure; thirdly, treating submerged plant transplants, wherein the treatment comprises clearing, trimming and soaking in plant growth hormone; fourthly, performing planting, culturing and seedling exercising on turf; finally, transporting the cultured composite submerged plant turf to a construction site, and fixing the composite submerged plant turf to bottom mud of water required for remediation. By the method, the turf is quickly and efficiently prepared, the survival rate of submerged plants is high, a community structure of the submerged plants is more complicated, large scale production can be implemented, the turf is convenient to plant, manpower is saved and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the fields of freshwater 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 water eutrophication survey conducted by the United Nations Environment Program (UNEP) shows that 30% to 40% ...

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
