Problems solved by technology

Although this method is effective for Cladophora floating on the water surface, the cost is relatively high, and it does not involve the treatment of Cladophora attached to the water matrix or entangled on the surface of submerged plants.

Embodiment 1

[0022] A kind of method for fast control clastic algae, comprises the following steps:

[0023] Step 1: In this implementation area, Cladophora grows entwined on the surface of the submerged plant Erythrina chinensis. The growth is crazy, and the water area is about 600m 2 , the average water depth is 1.2m, and the implementation water volume is 720m 3 ;

[0024] Step 2: The mass concentration of zinc sulfate used is 50g / m 3 , the consumption of water is 10% of zinc sulfate quality. According to the volume of the water area, the dosage of zinc sulfate is 36kg, and the dosage of water is 3.6kg. Dissolve zinc sulfate in water to form a turbid state;

[0025] Step 3: the mass ratio of sedimentation agent to zinc sulfate is 0.5:1.0, 18kg of sand is added to the mixed solution of zinc sulfate in the previous step, and stirred and mixed evenly;

[0026] Step 4: Sprinkle the mixture prepared in the previous step into the water body manually, and the zinc sulfate will settle to th...

Embodiment 2

[0028] A kind of method for fast control clastic algae, comprises the following steps:

[0029] Step 1: In this implementation area, Cladophora grows entwined on the surface of submerged plants Erythrina galenica, and some Cladophora floats on the water surface. The growth of Cladophyllum in the entire water body is crazy, and the water area is about 1000m 2 , the average water depth is 1m, and the implementation water area volume is 1000m 3 ;

[0030] Step 2: The mass concentration of zinc sulfate used is 30g / m 3 , the consumption of water is 20% of zinc sulfate quality. According to the volume of the water area, the dosage of zinc sulfate is 30kg, and the dosage of water is 5.0kg. Dissolve zinc sulfate in water to form a turbid state;

[0031] Step 3: the mass ratio of sedimentation agent and zinc sulfate is 2.0:1.0, and the bentonite of 60kg is added in the mixed solution of zinc sulfate in the previous step, and stirred and mixed evenly;

[0032] Step 4: Sprinkle the m...

Embodiment 3

[0034] A kind of method for fast control clastic algae, comprises the following steps:

[0035] Step 1: Cladophora in this implementation area mainly grows on the surface of landscape stones in the water body, and grows explosively. The water area is about 64m 2 , the average water depth is 0.5m, and the implementation water area volume is 32m 3 ;

[0036] Step 2: The mass concentration of zinc sulfate used is 10g / m 3 , the consumption of water is 40% of zinc sulfate quality. According to the volume of the water area, the dosage of zinc sulfate is 320g, and the dosage of water is 80g, and the zinc sulfate is dissolved in water to form a turbid state;

[0037] Step 3: The mass ratio of sedimentation agent to zinc sulfate is 1.0:1.0, and 320g of clay is added to the mixed solution of zinc sulfate in the previous step, and stirred and mixed evenly;

[0038] Step 4: Sprinkle the mixture prepared in the previous step into the water body manually, and the zinc sulfate will settl...

Abstract

The invention discloses a method for preventing and treating cladophora, and belongs to the technical field of harmful algae control in water environment protection. The method comprises: selection ofa treatment water area: determining the volume of a treatment water area; preparation of an algicide: mixing a certain mass of zinc sulfate and a small amount of water; mixed preparation of a settling agent and the algicide: adding a settling agent into the prepared zinc sulfate mixed solution according to a certain ratio; and throwing settling: manually throwing into the water body, and settlingthe zinc sulfate to the surface of cladophora in the water body under action of the gravity of the settling agent. According to the invention, the method has advantages of simple and rapid cladophoraprevention and treatment, significant effect, low cost and safety to water and aquatic animals and plants.

Description

technical field [0001] The invention discloses a method for preventing and controlling Cladophora, and specifically belongs to the technical field of controlling harmful algae for water environment protection. Background technique [0002] Cladophora is a common filamentous green alga belonging to the Chlorophyta Cladophora genus. The cells are long and cylindrical. The larvae are a reticular chloroplast, and the adults are multiple granules with multiple starch nuclei and multiple nuclei. . The cell wall is thick and lamellar, the outermost layer is chitin. Cladophora starts to grow in April every year, and it will have a growth period of about half a year until October. The suitable temperature for growth is 10-40°C. It has strong adaptability and can reproduce asexually or produce zoospores. Sexual reproduction is isogamous. Due to the special cell structure, strong fecundity and reproductive ability and strong adaptability of Cladophora, not only has it caused serious ...
