Potassium diformate, sechinhu chitsva chekuwedzera chekudya, chakaratidza kukosha kwekushandisa muindasitiri yezve aquaculturemumakore achangopfuura. Iyo yakasarudzika inorwisa mabhakitiriya, inosimudzira-kukura, uye yemvura-inovandudza mhedzisiro inoita kuti ive yakanakira imwe nzira yemishonga inorwisa mabhakitiriya.

1. Antibacterial Effects uye Disease Prevention
Iyo antibacterial mechanism yepotassium diformatekunyanya inovimba nefomic acid uye maion efomate anoburitswa mudumbu remhuka. Tsvagiridzo inoratidza kuti kana iyo pH iri pazasi 4.5, potassium diformate inogona kuburitsa formic acid mamorekuru ane yakasimba bactericidal mhedzisiro. Ichi chivakwa chinoratidza akakosha inhibitory mhedzisiro pane akajairika pathogenic mabhakitiriya mumhuka dzemumvura, senge Aeromonas hydrophila uye Edwardsiella. Semuenzaniso, mukuyedza nePacific white shrimp kurima, kuwedzera 0.6% potassium formate yekudyisa yakawedzera shrimp kupona mazinga ne12% -15% uku ichideredza intestinal kuzvimba chiitiko neanenge 30%. Zvinonzwisisika, iyo antibacterial efficacy ye potassium diformate inoenderana nedosi, asi kuwedzera zvakanyanya kunogona kukanganisa kunaka. Iyo inokurudzirwa dosage inowanzobva pa0.5% kusvika 1.2%.

2. Kurudzira kukura uye kushandura chikafu
Potassium diformateinowedzera kukura kwemhuka dzemumvura kuburikidza nenzira dzakawanda:
-Deredzai pH kukosha kwegumbo rekudya, activate pepsinogen, uye uvandudze mapuroteni digestion rate (experimental data inoratidza kuti inogona kuwedzera ne8% -10%);
-Kudzivisa mabhakitiriya anokuvadza, kukurudzira kupararira kwebhakitiriya inobatsira yakadai selactic acid mabhakitiriya, uye kuvandudza kuenzana kwemukati microbiota;
-Enhance mineral absorption, kunyanya mashandisiro ekushandisa kwezvinhu zvakaita secalcium uye phosphorus. Mukurima carp, kuwedzera 1% potassium diformate kunogona kuwedzera uremu hwezuva nezuva ne6.8% uye kuderedza kushanda kwekudya ne0.15%. Kuedza kweaquaculture yeSouth America white shrimp yakaratidzawo kuti boka rekuedza raive ne 11.3% kuwedzera kwehuwandu hwehuremu kana ichienzaniswa neboka rekutonga.

3. Basa rekuvandudzwa kwemvura
Iyo metabolic yekupedzisira zvigadzirwa zve potassium diformate icarbon dioxide nemvura, izvo zvisingarambe zviri munharaunda yeaquaculture. Iro antibacterial effect inogona kuderedza kubudiswa kwebhakitiriya yepathogenic mumarara, zvisina kunanga kuderedza kusanganiswa kweammonia nitrogen (NH ∝ - N) uye nitrite (NO ₂⁻) mumvura. Tsvagiridzo yakaratidza kuti kushandiswa kwe potassium diformate feed mumadziva emumvura kunoderedza huwandu hwenitrogen hwemvura ne18% -22% zvichienzaniswa neboka rinowanzoitwa, iro rinonyanya kukosha kune yakakwirira-density aquaculture masisitimu.

4. Chikumbiro chekuchengetedzwa kwekuongorora
1. Toxicological kuchengeteka
Potassium diformate yakanyorwa se "yasara yemahara" yekuwedzera chikafu neEuropean Union (EU nhamba yekunyoresa E236). Iyo acute toxicity bvunzo yakaratidza kuti LD50 yayo yekuredza yakakura kupfuura 5000 mg/kg uremu hwemuviri, chiri chinhu chisiri chepfu. Mumazuva makumi mapfumbamwe ekuyedza, uswa hwecarp hwakadyiswa chikafu chine 1.5% potassium diformate (3 nguva inokurudzirwa dose) pasina chero chiropa kana itsvo kusagadzikana kana histopathological shanduko. Zvakakosha kuziva kuti kune misiyano mukushivirira kwemhuka dzakasiyana dzemumvura kune potassium diformate, uye crustaceans (yakadai se shrimp) inowanzova nepamusoro-soro yekushivirira kupfuura hove.

2. Kusarira kwesangano uye nzira dzemagetsi
Radioisotope yekutevera zvidzidzo zvakaratidza kuti potassium diformate inogona kunyatsogadziriswa muhove mukati memaawa makumi maviri nemana, uye hapana prototype yakasara inogona kuonekwa mumamhasuru. Iyo metabolic maitiro haaburitse chepfu yepakati uye inosangana nekuchengetedza chikafu zvinodiwa.

3. Kuchengetedzwa kwezvakatipoteredza
Potassium diformate inogona kukurumidza kuderedzwa munzvimbo dzechisikigo nehafu yehupenyu hwemaawa angangoita makumi mana nemasere (pa25 ℃). Ongororo yengozi yezvakatipoteredza inoratidza kuti hapana kukanganisa kukuru pazvirimwa zvemumvura (seElodea) uye plankton pasi pemashandisirwo akajairika. Nekudaro, zvinofanirwa kucherechedzwa kuti munzvimbo dzakapfava dzemvura (kuoma kwese <50 mg / L), muyero unofanirwa kuderedzwa zvakakodzera kuti udzivise pH kushanduka.

4. Kuronga kwekushandisa kwemwaka
Inokurudzirwa kuishandisa mune zvinotevera mamiriro:
-Kunyanya kupisa mwaka (tembiricha yemvura> 28 ℃) inguva ine njodzi yezvirwere;
-Kana mutoro wemvura wakakwirira pakati uye gare gare matanho e aquaculture;
-Panguva yekunetsekana sekuendesa mbesa kumadziva kana kupatsanura kuita madziva.

Potassium diformate, nemabasa ayo akawanda uye chengetedzo, iri kuumbiridzazve kudzivirira nekudzora hurongwa hwechirwere mu aquaculture.

Mune ramangwana, zvinodikanwa kusimbisa indasitiri yekutsvagisa yunivhesiti, kuvandudza tekinoroji zviyero, uye kusimudzira kugadzwa kwemhinduro yakazara kubva pakugadzira chikafu kusvika kune aquaculture terminals, kuitira kuti iyi yegirinhi yekuwedzera inogona kuita basa rakakura mukuona kuchengetedzwa kwemhuka dzemumvura uye.kukurudzirabudiriro inogoneka.
