Description
Technical field
The present invention relates to drive away the preparation of disease bacterium such as assorted algaes such as the diatom that produces in the laver culture, green alga and red rotten bacterium, chytrid, absorption bacterium.
Background technology
In laver culture, because assorted algae propagations such as diatom are online attached to laver leaf body or laver, hindered the growth of laver, even also had the situation of the death that causes laver.Even the no problem diatom that grows is adsorbed on the laver leaf body, when should former algae making product, can sneak into green spot in the dried laver of black, cause falling commodity price.Also taste hardship, unpalatable laver when edible.In addition, can cause laver that corruption, whole dead situations are arranged if produce red rotten bacterium, chytrid, absorption bacterium during laver culture.
Therefore, in order to drive away assorted algae such as diseases such as red rotten bacterium and diatom, carry out acid treatment or parch operation.Parch operation the shortcoming that workload is big, operation is poor, effect is little is arranged.Though adopt acid-treated expelling method than parching the effective of method now, can not reach ideal effect.Also producing cost increases, the problem that environmental pressure strengthens.
The report that the inorganic agent that following described laver culture uses is arranged up to now.The spy opens and has put down in writing in the clear 50-121425 communique that to contain the representative examples of saturated aliphatic monocarboxylic acid, the carbon number that are selected from carbon number 1 to 4 be that one or two or more kinds organic carboxyl acid of 2 to 4 saturated or unsaturated dicarboxylic, gluconic acid, lactic acid, tartaric acid, malic acid, citric acid is as the algicide of active ingredient.
Put down in writing in the Te Kaiping 11-286407 communique to contain the diatom expeling inorganic agent that lactic acid and/or acetate and p-hydroxybenzoate are feature.
Put down in writing in the special public clear 60-13647 communique by at the citric acid that contains 0.3～5.0%, pH soaks in 1.0～6.0 the treatment fluid, drives away, the laver culture method of the assorted algae of prevention and disease.
Be 1.0～4.0 by adding inorganic acid for adjusting pH such as hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid in the special public clear 60-13648 communique, drive away, the laver culture method of the assorted algae of prevention and disease.
Acidic treatment soaks 10～15 minutes by the laver net is taken out blocks ofly in pickling agent, then that the laver net is stretching method.Recently, because a culturist's breed sheet number increases, the time of every processing must shorten, so just progressively adopt fixing laver net to sail to carry out the acid treatment method of acid-treated so-called " cross and do not go into processing ".Because the fixing direct acid treatment of laver net can be carried out acid treatment with existing 1/5～1/10 time.But because the processing time is 10 seconds～5 minutes a weak point, carrying out acid treatment with the acid concentration of existing 0.1～0.5W/V% does not have effect, so adopt the high concentration of 2～10W/V% to handle.Even so there is not effect of sufficient yet.Usage amount increases severely and also produces Cost Growth, the problem of environmental pollution burden.
In addition, report is also arranged, improve osmotic pressure and improve acid-treated effect (spy opens flat 9-201180 communique) by adding mineral salt.But,, must in treatment fluid, add the salt of number %～10% in order to make proportion more than 1.030.Obtain certain treatment effect, treatment fluid must guarantee certain proportion, keeps its concentration for being very difficult technology with adding a large amount of salt in the operation of carrying out of working continuously, and operating efficiency is not high yet.
In general, treatment fluid is adjusted into about 1000L, handles 40～100 laver nets in 1 day, when the salinity of keeping 5% is handled, must need the salt of 20～40L acidic treatment agent and 200～400kg in 1 day.It is difficult transporting the salt of 400kg and be dissolved into certain ratio on small-sized acid treatment ship, is unusual onerous toil simultaneously.Because laver culture carries out in the high landlocked inlet of closure, if the laver culture person carries out acid-treated words all in this way, the proportion in the seawater will raise, and might destroy the ecosystem.
In sum, urgent hope exploitation is safe, low concentration, treatment fluid that operability is good and processing method.
Summary of the invention
The objective of the invention is to, inorganic agent and the processing method of at low concentration, short time in driving away disease bacterium such as assorted algae such as diatom, green alga and red rotten bacterium, chytrid, absorption bacterium harmless to laver self is provided.
For addressing the above problem, found that of further investigation is contained one or more organic acid, inorganic acid and iron sulfate and the treatment fluid of proportion less than 1.030 by use, can use low concentration when laver culture, the short time drives away, algae and disease are mixed in prevention.
That is to say that the present invention is as described below.
(1) a kind of assorted algae of driving away and producing during the prevention laver culture and disease kill the algae bactericide, it is characterized in that, contain the solution of more than one and sulphate of iron in organic acid, the inorganic acid, and solution proportion less than 1.030.
(2) the algae bactericide of using according to the laver culture described in (1) extremely is characterized in that the content of acid is 0.01～2W/V%, and the content of sulphate of iron is 0.01～1.0W/V%.
(3) according to killing the algae bactericide described in (1) or (2), it is the inorganic agent that the solution dilution that will contain the sulphate of iron of the acid of 1～99W/V% and 1～99W/V% obtains.
(4) according to the described laver culture in (1)～(3) algae bactericide extremely, it is characterized in that sulphate of iron is the sulphate of iron that is selected from ferrous sulfate, iron sulfate, ferric subsulfate.
(5) adopt according to the described laver culture in (1)～(4) the algae method for disinfection extremely that kills the algae bactericide, it is characterized in that the processing time is 10 seconds～5 minutes.
From testing example as can be seen, use acid or sulphate of iron not to drive away the effect of red rotten bacterium, diatom separately, by making the combination of acid and sulphate of iron, the low acid concentration with 0.1～2% just can be driven away red rotten bacterium.And, can in 10 seconds～5 minutes short time, drive away red rotten bacterium.
The algae bactericide that kills of the present invention can obtain by the treatment fluid of being made up of the mixed liquor of the sulphate of iron of 1～99% acid and 1～99% with the seawater dilution.Can use the solution of the sulphate of iron that contains 0.01～2% acid and 0.01～0.7% to handle.In addition, also can distinguish dilute acid and sulphate of iron solution mixes use again.
