Embodiment 1
[0028] A method for constructing lakeside wetland emergent plant communities, comprising the following steps:
[0029] S1. Select the lakeside shallow water area of Haizhu Lake in Guangzhou City with a water depth of less than 0.5 meters as the planting area for emergent plants;
[0030] S2. Construct the emergent plant community in the selected planting area: the emergent plants are papyrus, calamus, canna, barracuda; in terms of spatial configuration, papyrus, calamus, and canna are planted respectively from the shallow water area to the shore , barracuda (namely community 1);
[0031] S3. After the planting is completed, pest control should be carried out in time, and weeds and duckweed-like harmful plants in the plant area should be removed in time to prevent the adverse effects of excessive accumulation of harmful aquatic plants on emerging plants.
[0032] Among them, the plant height and number of tillers of emergent plants are: Canna ≥ 0.5 meters, 3; Barracuda ≥ 0.3...
Embodiment 2
[0035] A method for constructing lakeside wetland emergent plant communities, comprising the following steps:
[0036] S1. The planting area of emergent plants is selected as tidal flats or islands formed by blowing and filling the lakeside with sediment. The beach elevation of tidal flats or islands should ensure local dew or average water depth in the basement restoration area during the planting season in spring and summer. The range is 0-0.3 meters, and the bandwidth of the repair area is 1-5 meters;
[0037] S2. Construct the emergent plant community in the selected planting area: the emergent plants are papyrus, calamus, canna, pikegrass; mainly calamus, and the rows of calamus are mixed with paper from the shallow water area to the bank Sedge rows, canna rows, pike grass rows;
[0038] S3. After the planting is completed, pest control should be carried out in time, and weeds and duckweed-like harmful plants in the plant area should be removed in time to prevent the a...

Abstract
The invention relates to the technical field of wetland plant building, and discloses a building method of an aquatic-terrestrial wetland emergent plant community. The method comprises the following steps that firstly, an aquatic-terrestrial shallow water area with the depth lower than 0.5 meter is selected to serve as an emergent plant growing region; secondly, the emergent plant community is built in the selected growing region, wherein the emergent plant comprises cyperus papyrus, acorus calamus, India canna and pontederia cordata, and according to spatial arrangement, cyperus papyrus, acorus calamus, India canna and pontederia cordata are planted from the shallow water area to a side respectively; thirdly, after planting is completed, pest and disease control is conducted in time, and weeds and duckweed noxious plants are cleared away in time. The community composed of the four species of emergent plants including cyperus papyrus, acorus calamus, India canna and pontederia cordata has a high purification effect on eutrophic waters, is capable of keeping the stability of the wetland aquatic plant community, and has an important significance on ecological remediation of the eutrophic waters; the four species of emergent plants are matched reasonably to form the emergent plant community adapting to local natural environmental conditions, and the wetland landscape effect is enhanced.
Description
technical field [0001] The invention relates to the technical field of wetland plant construction, and more specifically, to a method for constructing lakeside wetland emergent plant communities. Background technique [0002] Wetland is a unique ecosystem formed by the interaction of water and land on the earth. It is the ecological landscape with the richest biodiversity in nature and one of the most important living environments for human beings. With the in-depth study of wetlands, the research direction of wetland plants is no longer limited to its decontamination mechanism, and gradually focuses on the structural characteristics of wetland plant communities, biodiversity, spatial and temporal dynamic changes of communities, community succession, and plant ecology. Restoration, research on the relationship between plant community structure and water environment. [0003] In view of the fact that the wetlands in southern my country are generally polluted and have a high ...
