Problems solved by technology

[0006] However, the overgrowth of submerged plants will also cause some environmental problems. When submerged plants grow to a certain extent, they will break off their roots and fall off. Nitrogen, phosphorus and organic matter enter the water body, causing secondary pollution, affecting water quality and destroying the water ecological environment
At the same time, overgrown submerged plants will affect the growth of other aquatic organisms

Embodiment 1

[0034] The present embodiment is a method for compound planting submerged plants with different root-shoot ratios to purify pond water quality, which is realized in the following steps:

[0035] 1) Level and clean the pond base

[0036] Level the pond base and remove large rocks and other debris.

[0037] 2) Divide the grid

[0038] Divide the pond base into several 50cm*50cm square grids.

[0039] 3) Select submerged plants with different root-shoot ratios that have been cultivated

[0040] For submerged plants with a high root-cap ratio, choose Erythronia elegans, and for submerged plants with a low root-cap ratio, select Elodea, and use Elodea as a single Elodea without branches.

[0041] 4) Determine the planting location of bitter grass

[0042] The four vertices of the grid and the 1 / 3 and 2 / 3 positions of each side are the bitter grass planting positions, and one bitter grass is planted at each position, and the distance between the planting points of each bitter gr...

Embodiment 2

[0053] This embodiment is a method for purifying river water quality by planting submerged plants with different root-to-shoot ratios (Littleweed, Elodea) compoundly.

[0054] 1) Leveling and cleaning the river base

[0055] Level the channel base and remove large rocks and other debris.

[0056] 2) Divide the grid

[0057] Divide the channel base into a square grid of 50cm*50cm

[0058] 3) Determine the planting location of bitter grass

[0059] The four vertices of the grid and the 1 / 3 and 2 / 3 positions of each side are the bitter grass planting positions, and one bitter grass is planted at each position, and the distance between each bitter grass planting point is 16-17cm .

[0060] 4) Determine the planting range of Elodea

[0061] Each square area in the grid is the Elodea planting area, and each area is planted in 3 rows and 3 columns, with a total of 9 Elodea plants, and the distance between each planting hole is 8-13cm, and the distance between the boundary of the E...

Embodiment 3

[0070] This example is a method for purifying lake water quality by planting submerged plants with different root-to-shoot ratios (Littleweed, Elodea), which is implemented according to the following steps:

[0071] 1) Level and clean the lake base

[0072] Level the lake base and remove large rocks and other debris.

[0073] 2) Divide the grid

[0074] Basically divide the pond into a square grid of 50cm*50cm

[0075] 3) Determine the planting location of bitter grass

[0076] The four vertices of the grid and the 1 / 3 and 2 / 3 positions of each side are the bitter grass planting positions, and one bitter grass is planted at each position, and the distance between each bitter grass planting point is 16-17cm .

[0077] 4) Determine the planting range of Elodea

[0078] Each square area in the grid is the Elodea planting area, and each area is planted in 3 rows and 3 columns, with a total of 9 Elodea plants, and the distance between each planting hole is 8-13cm, and the dist...

Abstract

The invention discloses a method for purifying a water body by planting submerged plants with different root-shoot ratios together. According to the method, at least two submerge plants with different root-shoot ratios are used. The method comprises the following steps: (1) choosing a water body to be purified, and flattening and clearing the substrate of the water body; (2) manufacturing field-planting grids; (3) choosing cultured submerge plants with different root-shoot ratios, and screening and trimming the submerge plants; (4) determining the planting positions for the submerge plants with different root-shoot ratios; (5) transplanting the submerge plants. By planting different submerge plants with different root-shoot ratios, the nutritive salt loads of water body and precipitates can be reduced, moreover, the different submerge plants can inhibit each other, the excess growth can be avoided, thus the whole water ecological system will not be influenced by the excessive submerge plants, and the method can finally purify the water body.

Description

technical field [0001] The invention relates to the field of ecological restoration of water bodies, in particular to a method for purifying water bodies by compositely planting submerged plants with different root-shoot ratios. Background technique [0002] In recent years, with the continuous development of production and living standards, the production of industrial sewage and domestic sewage has gradually increased, which are discharged into lakes, reservoirs, rivers and other water bodies, especially a large amount of sewage containing nitrogen and phosphorus, which eventually leads to eutrophication in water bodies. increase in chemical substances. The eutrophication of the water body leads to the excessive reproduction of phytoplankton, the decrease of the transparency of the water body, the decrease of the dissolved oxygen content, and finally the deterioration of the water quality, and the serious damage and destruction of the function of the water body ecosystem. ...
