Embodiment 1

[0018] The restoration site is a landscape water area of ​​about 3,000 square meters in Changsha City. Before the restoration, the transparency of the water body was 0.08m, and the water quality met the Class IV water standard. The specific steps are:

[0019] A. Water quality detection: firstly detect various indicators of water quality;

[0020] B. Removal of weeds: prepare the treated waters for weed removal;

[0021] C. Add photosynthetic bacteria: put photosynthetic bacteria into the water body, the ratio of photosynthetic bacteria liquid to water body is 1:350, and the total number of bacteria in the photosynthetic bacteria liquid is: 3-5×10 10 cfu / ml;

[0022] D. Implantation of submerged plants: After 20 days of restoration of the water body by photosynthetic bacteria, transplant the four submerged plants of bitter grass, hydrilla, glabra and sea cauliflower into the bottom mud of the water body, specifically bitter grass accounts for the total 68% of H. verticilliu...

Embodiment 2

[0026] The restoration site is about 2,000 square meters of water in a cultural park in Changsha City. Before the restoration, the transparency of the water body was 0.06m, and the water quality met the Class IV water standard. The specific steps are:

[0027] A. Water quality detection: firstly detect various indicators of water quality;

[0028] B. Weed removal: Weed removal in the water area to be treated, and preparatory work such as enclosure of the water area to be treated with geotextiles;

[0029] C. Add photosynthetic bacteria: put photosynthetic bacteria into the water body, the ratio of photosynthetic bacteria liquid to water body is 1:250, and the total number of bacteria in the photosynthetic bacteria liquid is: 3-5×10 10 cfu / ml;

[0030] D. Implantation of submerged plants: After 25 days of repairing the water body by photosynthetic bacteria, transplant the four submerged plants of bitter grass, hydrilla, glabra and sea cauliflower into the bottom mud of the wa...

Embodiment 3

[0034] The restoration site is a water area of ​​about 2,500 square meters in Changsha. Before the restoration, the transparency of the water body was 0.07m, and the water quality met the Class IV water standard. The specific steps are:

[0035] A. Water quality detection: firstly detect various indicators of the water quality of the water body to be treated;

[0036] B. Removal of weeds: prepare the treated waters for weed removal;

[0037] C. Add photosynthetic bacteria: put photosynthetic bacteria into the water body, the ratio of photosynthetic bacteria liquid to water body is 1:300, and the total number of bacteria in the photosynthetic bacteria liquid is: 3-5×10 10 cfu / ml;

[0038] D. Implantation of submerged plants: After 23 days of restoration of the water body by photosynthetic bacteria, transplant four submerged plants of bitter grass, hydrilla, glabra and sea cauliflower into the bottom mud of the water body, specifically bitter grass accounts for the total 65% ...

Abstract

The invention discloses a method for jointly constructing an underwater landscape ecosystem by utilizing submerged plants mainly composed of bitter grass and photosynthetic bacteria, and relates to the field of water quality purification and garden landscape. The main steps include: A, water quality detection; B, removing impurities Grass; C, putting photosynthetic bacteria; D, implanting submerged plants. It has the characteristics of good water purification effect, stable later stage, low energy consumption, and simple operation. It can quickly and effectively eliminate the eutrophication phenomenon of landscape water bodies, inhibit the growth of cyanobacteria, make the water body transparency reach more than 2m, and the water body water quality reach Class III water. standards, will not produce secondary pollution, and can create a green, beautiful and rich underwater landscape ecosystem.

Description

technical field [0001] The invention relates to the fields of water quality purification and garden landscape, in particular to a method for jointly constructing an underwater landscape ecosystem by using submerged plants mainly composed of bitter grass and photosynthetic bacteria. Background technique [0002] As primary producers in aquatic ecosystems, submerged plants can exert a variety of ecological functions. The roots affect the sediment, and the leaves directly affect the water layer. On the one hand, submerged plants can absorb nutrients in the water body and sediment, store or assimilate them into their own substances, and reduce the re-release of nutrients in the sediment; on the other hand, they can secrete allelochemicals to inhibit algae by competing with algae for resources Grow and multiply. Therefore, submerged plants can purify water well. [0003] Vallisneria natans (Lour.) Hara belongs to the genus Vallisneria L., an herbaceous evergreen submerged plant...
