Problems solved by technology

[0008] The devices involved in the above methods are cumbersome to manufacture and complicated to operate; Chinese patent CN102177807B discloses a method for rapid colonization of floating submerged plants hornwort algae, which relatively simplifies the planting facilities, can effectively improve the water quality and transparency of the water body, but still needs to use Bundle the hornwort with cloth strips, then connect the cloth strips with a fixed bag, and finally connect the hornwort to the fixed rod through a fixed rope. The two ends of the fixed rod are connected with fixed bags, which are not conducive to the growth of hornwort; therefore, it is necessary to develop new goldfish Algae growing method

Embodiment 1

[0021] Example 1: Experiment on the treatment of Shishou Mountain Lake in Hubei

[0022] The lake covers an area of ​​more than 700 mu, and the water quality is seriously polluted (bad Water quality), the water transparency is less than 20 cm. The selected test area is about 5 acres, using bamboo poles with a diameter of about 5 cm, piling seine nets and isolation cloth every 3-4 meters, and sprinkled about 6,000 catties of hornwort salvaged and cleaned from adjacent rivers for about a week Survival reached more than 80%, the water transparency in the Banyue test area increased to more than 50 cm, and the main eutrophication components such as N and P decreased by about 20%.

Embodiment 2

[0023] Example 2: Water Treatment of Youlong Lake in Zhuzhou, Hunan

[0024] The total area of ​​the water body is 120 mu, and the water quality is Water-like, transparency 30 cm. According to the natural direction of the lakeshore, bamboo piles are placed every 3 meters in some nearshore areas. The actual fence area is about 25 mu, and 1,500 jin of hornwort are sown per mu. The survival rate is more than 70% in about a week, and the water transparency reaches 20 days later. Nearly 80 cm, providing conditions for the planting of other aquatic plants.

Embodiment 3

[0025] Example 3: Water body treatment of Suzhou Wangshi Park

[0026] The water area is more than 500 square meters, the water color is dark yellow, and the water quality is seriously polluted (poor According to the terrain near the pond, wooden poles with a diameter of about 3 cm are used to fix the seine with piles at intervals of about 2 meters. The actual area of ​​the seine is about 300 square meters, and about 700 catties of goldfish are scattered. Algae, 90% of them survived in about 20 days, and their transparency reached 1 meter, providing conditions for the construction of water ecosystems.

Abstract

The invention discloses a method for carrying out seine planting of ceratophyllum demersum, which comprises the steps of piling, seining, selecting ceratophyllum demersum, planting and the like. The ceratophyllum demersum planting method is simple, binding does not need to be carried out, the survival rate is increased and cost is reduced; the method is not influenced by variation of the depth of the water level and has obvious effects; water quality of a water body can be effectively improved, transparency of the water body is improved, conditions are provided for planting other plants, and the method can be used as an advanced step in the eco-remediation process; the method is suitable for remediation engineering of water bodies in lakes and ponds and recovery engineering of diversity of aquatic animals and plants.

Description

technical field [0001] The invention relates to the technical field of resource and environmental engineering, in particular to a method for planting hornwort algae purse seines. Background technique [0002] At present, due to the widespread problems of substandard discharge of polluted water bodies, forest vegetation destruction, and intensified soil erosion, the nitrogen and phosphorus loads of rivers, lakes and other receiving water bodies have increased, water transparency has decreased, and water eutrophication has become prominent. The area of ​​aquatic vegetation shrinks and the biodiversity drops sharply, resulting in a large number of fish deaths, and also has adverse effects on industrial, domestic and irrigation water. [0003] At present, the methods of water body restoration mainly include physical, chemical and ecological methods. Compared with physical and chemical methods, ecological methods are the cheapest, safest, simple and effective method. Submerged v...
