preparation example Construction

[0062] Another embodiment of the present invention also provides a method for preparing the above-mentioned red tide algae inhibitory liquid, comprising the following steps:

[0063] Step 1: put sea iris in an oven and dry until the weight does not change, and grind the dried sea iris into sea iris powder with a grinder;

[0064] Step 2: adding solvent to the calamus calamus powder, stirring to dissolve the soluble substances in the solvent;

[0065] Step 3: filter to remove bacteria and particles, and obtain the extract of calamus calamus.

[0066] The solvent includes one or more of artificial seawater, ethanol and n-hexane;

[0067] When the solvent is artificial seawater, use a 0.22 μm cellulose acetate filter to remove particles and microorganisms;

[0068] When the solvent is ethanol or n-hexane, a 0.22 μm polyethersulfone filter membrane is used to filter out bacteria and particles.

[0069] When the solvent is ethanol or n-hexane, the obtained calamus extract is blo...

[0072] Example 1: Inhibitory effect of sea calamus water extract on four kinds of red tide algae

[0073] 1. The effect of the water extract of Acorus calamus on the cell density of four kinds of red tide algae

[0074] 1.1 Inhibitory effect of the water extract of Acorus calamus on Steinerella cone

[0075] The algae density of Steinerella coniformis in the water extract of Acorus calamus dry powder see figure 1 . Compared with the blank control group, 0.1g·L -1 The treatment group began to have an inhibitory effect on Steinerella cones on the fourth day, 0.1g·L -1 The density of algae in the treatment group was significantly lower than that of the blank control group from the fifth day to the eighth day (P-1 , 1g·L -1 , 2.5g·L -1 The density of algae in the treatment group was significantly lower than that in the control group (P-1 In the treatment group, the density of algae increased in the first three days, and the density of algae decreased from the fourth day, show...

Abstract

The invention provides a method for inhibiting red tide algae. The method is characterized by comprising the following step: performing growth inhibition on the red tide algae by utilizing an extractliquid of enhalus acodoides, wherein the extract liquid of the enhalus acodoides comprises one or more selected from the group consisting of a whole-plant extract liquid of the enhalus acodoides, a root extract liquid of the enhalus acodoides, a stem extract liquid of the enhalus acodoides, a leaf extract liquid of the enhalus acodoides, a flower extract liquid of the enhalus acodoides, and a fruit extract liquid of the enhalus acodoides. The invention also discloses an inhibiting liquid of the red tide algae and a preparation method of the inhibiting liquid. The invention aims to solve the problems that costs are high and secondary pollution is easy to produce in a current red tide algae treatment process.

Description

technical field [0001] The invention belongs to the field of red tide algae control, and in particular relates to a method for inhibiting red tide algae, a red tide algae inhibiting liquid and a preparation method thereof. Background technique [0002] Among the existing physical methods for inhibiting red tide algae, there are methods such as salvage, filtration, and sedimentation, but their range of action is small, they are easy to recur, and the cost is high. Chemical methods include copper ion algae killing method, surfactant, oxidant algicidal method, etc., which are not only costly but also easy to cause secondary pollution to the environment, cannot remove nutrients in the water body, and cannot effectively prevent red tide outbreaks. In fact, There are not many methods that can be used in practice. [0003] At present, some studies have found that large seaweeds such as asparagus have an inhibitory effect on red tide algae, and some studies have found that seaweed ...
