Abstract
The invention relates to a novel algicide, which is a biological preparation for controlling planktonic algae in a water body. The biological preparation is characterized by being a secondary metabolite-emodin derived from plants or artificially synthesized compound with the same structure. The biological preparation is applicable to planktonic algae such as blue-green algae, Cryptomonas, dinoflagellate, chrysophyceae, xanthophyceae, diatom, Euglena and green alga in the water body.
Description
Technical field the present invention relates to archen and kills algae compound and method for using thereof, belongs to water body environment protection field.
The pollution of background technology water body causes alga eruption, and the outburst of algae further increases the weight of the pollution of water body, seriously restricts Chinese economic development.The toxin that blue-green algae discharges brings great harm to people and animals.The algae that numerous scientific workers strive to find that exploitation is efficient, low toxicity, environment amenable algicide are killed water body prevents the generation of wawter bloom.
Archen is the middle pharmaceutically active ingredient of using always, is present in the plants such as polygonaceae, pulse family, has anti-ageing and interior polyradical and the antitumor action crossed of removing body.
Summary of the invention has found that archen has higher activity to planktonic algae in studying the natural products active process for many years.Through a large amount of indoor and outdoor tests, find archen under low concentration, blue-green algae, latent algae, dinoflagellate, chrysophyceae, xanthophyta diatom, Euglena and green alga etc. are had killing action, prevent the formation of wawter bloom.
The archen that the present invention obtains, they are secondary metabolites of plant, can be from plants, also synthetic material, but content of the present invention is not limited thereto.
The advantage that medicine of the present invention has is; The medicament that with the archen is effective ingredient is the secondary metabolite that plant produces in growth and development process; It is the medicine materical crude slice clinical commonly used of traditional Chinese medicine; It is a kind of novel algicide; Have characteristics such as low toxicity, low-residual and environmentally compatible, belong to novel biopesticide.In order to understand the present invention better, below in conjunction with embodiments of the invention, essentiality content of the present invention is described further, but content of the present invention is not limited thereto.
Embodiment
Embodiment 1: archen is to microcystic aeruginosa (Microcystis aeruginosa) determination of activity
Indoor nutrient solution is cultivated microcystic aeruginosa; Archen with the series concentration gradient adds in the algae culturing liquid then; Handle and measured the chlorophyllous content of microcystic aeruginosa in back 14 days, estimate the activity of this algae of Physcion according to the variation of microcystic aeruginosa chlorophyll content.Kill algae rate %=(chlorophyll content of blank chlorophyll content-processing)/(blank chlorophyll content) * 100, and calculate EC
50Value.The archen that test obtains is to microcystic aeruginosa EC
50Be 1.5mg/L.This result of the test shows that archen has good killing effect to microcystic aeruginosa.
Embodiment 2: Physcion is to wawter bloom anabena (Anabaena flosaquae)
Indoor nutrient solution is cultivated the wawter bloom anabena; Archen with the series concentration gradient adds in the algae culturing liquid then; Handle and measured the chlorophyllous content of microcystic aeruginosa in back 14 days, estimate the activity of this algae of Physcion according to the variation of wawter bloom anabena chlorophyll content.Kill algae rate %=(chlorophyll content of blank chlorophyll content-processing)/(blank chlorophyll content) * 100, and calculate EC
50Value.The archen that test obtains is to wawter bloom anabena EC
50Be 0.8mg/L.This result of the test shows that archen has good killing effect to the wawter bloom anabena.
Claims (2)
1. a novel algicide is characterized in that it is acceptable carrier in archen (Emodin) and the water body that this algicide contains the effective active composition.Can be used for killing planktonic algae in the water body, like microcystic aeruginosa (Microcystis aeruginosa), wawter bloom anabena (Anabaena flosaquae).
2. being plant and the microorganism extract that archen can come in the claim 1, also can be the artificial-synthetic compound.
