Ring its existence and breeding；(3) algae secretion or generation mucus, attach on the cheek of the aquatic animals such as fish, interfere breathing, cause
Death by suffocation；(4) algae toxin is secreted, algae toxin can damage nervous system, cause numb convulsions, dispute, expiratory dyspnea or even exhale
Failure is inhaled, also results in the damage of the organs such as diarrhea, vomiting, liver kidney, has and promotees the effects that knurl is carcinogenic.In addition, algae can also influence
Water supply quality simultaneously increases water producing cost, and excessive algae can bring obstacle, it is necessary to improve and increase to water factory processed in filter process
Add filtering measure.
In view of the above-mentioned problems, how to carry out having become the research hotspot of field of Environment Protection except algae.At present, algae side is removed both at home and abroad
Method mainly has Physical, chemical method and bioanalysis three categories.Physical method is the algae removed by manual work on the water surface, no
The nutriment of enrichment, which can fundamentally be solved, stimulates the effect of algal grown, and need to expend substantial amounts of man power and material into
Row is removed repeatedly, and cost is higher；Chemical algae removing agent has time effect that is short, quick, can quickly killing algae, but at present
Chemical algae removing drug can be enriched with, amplify in vivo, so as to the serious influence ecosystem；Biological algae removal mainly passes through
The pathogenic microorganism of algae is carried out except algae, but pathogen generates variation and other biological group can be generated greatly under field conditions (factors)
Ground influences, while the effect of pathogen has very big uncertainty.
The content of the invention
In view of the deficiencies of the prior art, the invention discloses a kind of algicide, the algicide is to come from the day of grape leave
Right ingredient is carried out for active material except algae, can not only effectively kill and inhibit the growth of algae, and clear efficacy is stablized, to ring
Border is without side-effects, has good ecological benefits and economic value.
Specifically, the present invention is achieved through the following technical solutions：
A kind of algicide, active ingredient are the methanolic extract of grape leave.
The experiment that applicant carries out shows that the methanolic extract of grape leave can substantially inhibit frustule growth.
In above-mentioned, applicant has used this saying of active ingredient, it will be appreciated by those skilled in the art that in actual system
During into commercially available finished product, often also need to add in type, the use of other shaping auxiliary materials or other auxiliary agents, these auxiliary materials and auxiliary agent
Amount etc., without special difference, can be universally used in the algicide of the present invention with the other similar formulations in this field.
Wherein, in algicide, extract concentrations are not less than 100mg/ml.The algicide of higher concentration is conducive to except algae
There is the killing scope of bigger in dilution.If extract concentrations are too low, it is unfavorable for giving full play to its inhibition frustule life
Long function.
Correspondingly, the invention discloses the preparation methods of the algicide, include the following steps：
1) grape leave of drying, is taken, methanol solution is added in after being fully ground, extracts first under room temperature, dark condition
Secondary methanol extract liquid；
2) the first methanol extract liquid of gained, is taken, gained methanol extract liquid is distilled in a heated condition, until by first
Alcohol has steamed, and water is added to adjust to aimed concn.
In above-mentioned, the relative usage of grape leave, methanol solution etc. can be adjusted with production environment as needed, first
Heating temperature etc. of alcohol distillation can the existing experiment of root root organic chemistry filed etc. be adjusted.
In general, in step 1), the dosage of grape leave and methanol solution causes first methanol extract liquid concentration to be not less than
100mg/ml；In step 2), aimed concn is not less than 100mg/ml for extract concentrations.
By controlling the concentration of each step, be conducive to simplify packaging and the application of subsequent product.
Further, the algicide the invention also discloses the present invention removes algae except the application in algae using the present invention
Agent carries out the method except algae, is that algicide is added in algae solution.
After algicide is added in algae solution, the too low growth for being unfavorable for inhibiting alga cells of active ingredient concentration is excellent
Choosing, in algae solution, for the methanolic extract concentration of grape leave not less than 12mg/ml, processing time is not less than 12h.
The experiment that applicant carries out in a variety of algae is shown, is used to inhibit and kill common using the algicide of the present invention
