MPT [Nta] :

Cov khoom no tsim nyog rau kev nuv ntses txhua xyoo puag ncig, thiab tsim nyog dua rau thaj chaw qis-siab thiab qhov chaw nuv ntses dej txias.

Thaum tsis muaj pa oxygen hauv dej, nws yog qhov zoo tshaj plaws los xaiv DMPT cov cuab yeej. Haum rau ntau hom ntses (tab sis qhov ua tau zoo ntawm txhua hom ntses yuav txawv), nrog rau ntau tus ntses sib sau ua ke thiab lub sijhawm ntev, thiab kev ua tau zoo heev hauv cov dej uas tsis muaj pa oxygen. Nws tuaj yeem ua rau muaj kev lom zem thiab kev ua tiav rau cov neeg nyiam nuv ntses.

Cov khoom xyaw tseem ceeb:

Dimethyl- β- Propiothetin, purity ntau dua 98% lossis 85%.

[kev siv thiab koob tshuaj]:

1. Haum rau cov ntses uas noj tau txhua yam (cov ntses crucian carp, ntses carp, ntses bream), ntses uas noj zaub (cov ntses nyom), ntses lim dej (cov ntses silver carp, cov ntses bighead carp), thiab ntses uas noj nqaij (cov ntses catfish, cov ntses catfish daj, tom qab hnov ​​tsw ntxhiab ntawm lawv lub zes, yuav tsum dai zaub mov tsiaj rau ntawm tus nuv), nrog rau cov ntses crustaceans xws li cw thiab vaub kib hauv dej qab zib. Cov ntses hauv dej hiav txwv yuav tsum tau muab cov tshuaj no ntub tag ua ntej.

2. Kev nuv ntses hmo ntuj, kev nuv ntses Taiwan yog qhov zoo tshaj plaws, thiab nws kuj siv tau ua tus pas nuv ntses rau cov khoom noj txom nyem.

3. Cov pas dej, cov pas dej loj, cov dej ntws, cov chaw khaws dej, thiab cov dej hiav txwv ntiav. Siv cov dej uas muaj cov pa oxygen ntau tshaj 4 milligrams ib liter yam tsis muaj qhov tsis txaus oxygen.

4. Nws yog qhov zoo tshaj plaws los ntxiv 0.5-1.5 grams ntawm DMPT thaum lub sijhawm ua zes kom sai sai nyiam cov ntses rau hauv lub zes. Thaum npaj cov cuab yeej, qhov feem pua ​​​​​​ntawm cov khoom noj qhuav yog 1-5%, uas txhais tau tias 5 grams ntawm DMPT thiab 95 grams txog 450 grams ntawm cov khoom noj qhuav tuaj yeem sib xyaw kom sib npaug.

5. DMPT tuaj yeem yaj rau hauv dej distilled lossis dej purified, thiab tom qab ntawd diluted rau cov kua concentration siab dua kom sib tov nrog cov kab nuv ntses. Kev siv cov kab nuv ntses thiab cov kab nuv ntses yog tib yam, yog li qhov sib xws ntawm DMPT hauv cov kab nuv ntses yuav siab dua. Tsis tas li ntawd, DMPT tuaj yeem sib xyaw ua ntej nrog cov khoom siv hmoov hauv cov khoom siv kab nuv ntses los ntawm kev muab tso rau hauv cov hnab yas kaw nruj nreem lossis cov hnab kuaj thiab co lawv rov qab thiab tawm kom ntseeg tau tias sib tov tiav thiab sib xws. Tom qab ntawd, 0.2% concentration ntawm DMPT aqueous kua tuaj yeem ntxiv rau kev hloov kho.

Tsis tas li ntawd xwb, txhawm rau kom tsis txhob sib xyaw nrog lwm cov ntses uas muag hauv khw thiab hloov lawv cov yam ntxwv thiab tsw, nws raug pom zoo kom cov phooj ywg nuv ntses sim siv cov ntses uas yog cov nplej ntshiab. Tau kawg, yog tias cov ntses uas yog cov nplej ntshiab tsis muaj, cov ntses uas muag hauv khw kuj siv tau.

Koj tuaj yeem ua cov ntses ua los ntawm cov nplej ntshiab los yog cov ntses ua los ntawm cov ntses. Piv txwv li, qhov piv ntawm DMPT uas muaj zog heev yog raws li nram no: 5 grams ntawm DMPT, yaj ua ntej hauv 100 milliliters dej ntshiab, do kom sib npaug thiab yaj tag ua ntej sib xyaw nrog 95 grams ntawm cov ntses qhuav, thiab qhov seem 0.2% ntawm cov kua dilute ntxiv raws li qib ntawm qhov qhuav thiab ntub. (5%) Piv txwv ntawm qhov piv ntawm DMPT uas muaj zog tsawg: 5 grams ntawm DMPT, yaj ua ntej hauv 500 milliliters dej ntshiab, do kom sib npaug thiab yaj tag, siv los sib xyaw nrog 450 grams ntawm cov ntses qhuav, thiab ntxiv nrog 0.2% ntawm cov kua dilute raws li qib ntawm qhov qhuav thiab ntub. (1%) Kev npaj cov kua dilute DMPT: 2 grams ntawm DMPT, yaj ua ntej hauv 1000 milliliters dej (0.2%), npaj ua cov kua dilute rau kev siv yav tom ntej. Kev Npaj DMPT thiab cov kab nuv ntses qhuav (1%): Siv 5 grams ntawm DMPT thiab 450 grams ntawm lwm yam khoom siv raw thiab muab tso rau hauv lub hnab yas kaw zoo, co rov qab thiab tawm, thiab sib tov kom sib npaug. Tom qab coj lawv tawm, ntxiv cov tshuaj 0.2% DMPT dilute kom txaus los npaj cov kab nuv ntses xav tau. Kev Npaj DMPT thiab cov kab nuv ntses qhuav (2%): Siv 5 grams ntawm DMPT thiab 245 grams ntawm lwm yam khoom siv raw thiab muab tso rau hauv lub hnab yas kaw zoo, co rov qab thiab tawm, thiab sib tov kom sib npaug. Tom qab coj lawv tawm, ntxiv cov tshuaj 0.2% DMPT dilute kom txaus los npaj cov kab nuv ntses xav tau. Kev Npaj DMPT thiab cov kab nuv ntses qhuav (5%): Siv 5 grams ntawm DMPT thiab 95 grams ntawm lwm yam khoom siv raw thiab muab tso rau hauv lub hnab yas kaw zoo, co rov qab thiab tawm, thiab sib tov kom sib npaug. Tom qab coj lawv tawm, ntxiv cov tshuaj 0.2% DMPT dilute kom txaus los npaj cov kab nuv ntses xav tau.

6. Nws yog qhov zoo tshaj plaws los npaj koj tus kheej cov cuab yeej, vim DMPT tau faib sib npaug zos hauv cov cuab yeej, nrog rau qhov nrawm sib npaug hauv dej thiab lub sijhawm ntev dua. Yog tias nws yog cov cuab yeej ua tiav lawm, nws kuj tuaj yeem muab tso rau hauv ib hmos hauv cov tshuaj DMPT sib xyaw ua ke.
