Embodiment 1

[0023] An environment-friendly algicide, the algae inhibitor is garlic water extract.

[0024] The garlic water extract is prepared by the following method: peel off the outer skin of fresh garlic bulbs, rinse them with distilled water, blot them dry with filter paper, cut them into pieces, put them into a mortar and grind until the garlic bulbs are less than 40 mesh, and form a grinding liquid , add 5 times the volume of water to the grinding liquid, mix evenly, place it on a shaker and shake for 24 hours, and filter it; the density of the garlic water infusion is 1.195 mg·mL -1

Embodiment 2

[0026] An environment-friendly algicide, the algae inhibitor is garlic water extract.

[0027] The garlic water extract is prepared by the following method: peel off the outer skin of fresh garlic bulbs, rinse them with distilled water, blot them dry with filter paper, cut them into pieces, put them into a mortar and grind until the garlic bulbs are less than 40 mesh, and form a grinding liquid , add 5.5 times the volume of water to the grinding solution, mix evenly, place it on a shaker and shake for 36 hours, and filter it; the density of the garlic infusion is 1.162 mg·mL -1

Embodiment 3

[0029] An environment-friendly algicide, the algae inhibitor is garlic water extract.

[0030] The garlic water extract is prepared by the following method: peel off the outer skin of fresh garlic bulbs, rinse them with distilled water, blot them dry with filter paper, cut them into pieces, put them into a mortar and grind until the garlic bulbs are less than 40 mesh, and form a grinding liquid , add 6 times the volume of water to the grinding liquid, mix evenly, place on a shaker and shake for 48 hours, filter, and the density of the garlic water infusion is 1.157 mg·mL -1

Abstract

The invention discloses an environmentally friendly algaecide, wherein the algaecide is garlic water extract or garlic lactic acid extract. Compared with the prior art, the algaecide has the characteristics of strong algae inhibition effect and low environmental toxicity.

Description

technical field [0001] The invention belongs to algae inhibitors, in particular to the technical field of environment-friendly algae inhibitors. Background technique [0002] The frequent occurrence of cyanobacterial blooms due to eutrophication of water bodies has become a global environmental problem. Cyanobacteria blooms not only lead to the deterioration of the aquatic ecological environment, but also pose a threat to human health due to the algal toxins they secrete (Alexander et al., 2017). Therefore, how to effectively reduce cyanobacterial blooms has been one of the hot research topics in the field of water environment in recent years (Thomas et al., 2012). Allelopathy of plants is considered to be a safe and effective method for biological control of algae (Wang et al., 2017). A large number of studies have reported that submerged plants such as Myriophyllum spicatum L., Ceratophyllum demersum L., and Chara vulgaris have very good anti-algae effects. The fatty aci...
