Kuchenesa ndiro dzePetriinzira inonetesa, asi maitiro aya anogona kuita kuti kuyedza kuve nyore. Kana dhishi rePetri risina kucheneswa, muyedzisi anofanira kutambisa nguva yakawanda achigadzirisa data rekuyedza. Uye kana dhishi rePetri rakacheneswa zvakakwana, muyedzisi anogona kuita kuyedza uku zvinobudirira.
Kuchenesa ndiro dzePetri nemaoko:
Kazhinji, inopfuura nematanho mana ekunyika, kukwesha, kusukuta, uye kuchenesa.
1. Kunyika: Magirazi matsva kana akamboshandiswa anofanira kunyikwa mumvura kutanga kuti apfave nekunyungudutsa zvakabatanidzwa. Magirazi matsva anofanira kungokweshwa nemvura yepombi usati washandisa, wozonyikwa husiku hwese mu5% hydrochloric acid; magirazi akamboshandiswa anowanzova nemapuroteni nemafuta akawanda, izvo zvisiri nyore kusuka mushure mekuomeswa, saka anofanira kunyikwa mumvura yakachena mushure mekushandisa kukwesha.
2. Kukwesha: Isa magirazi akanyikwa mumvura ine sipo woakwesha kakawanda nebhurashi rakapfava. Usasiye nzvimbo yakafa uye kudzivirira kukuvara pamusoro pemidziyo. Geza uye omesa magirazi akacheneswa kuti anyungudutswe.
3. Kunyudza: Kunyudza zvinoreva kunyikisa midziyo yataurwa pamusoro apa mumushonga wekuchenesa, unozivikanwawo semushonga weasidhi, kubvisa zvinhu zvinogona kusara pamusoro pemidziyo kuburikidza nekunyudza kwakasimba kwemushonga weasidhi. Kunyudza hakufanirwe kudarika maawa matanhatu, kazhinji husiku hwese kana kupfuura. Chenjerera midziyo.
4. Sukurudza: Midziyo mushure mekukwesha nekunatsa inofanira kusukwa nemvura zvakakwana. Kana midziyo yakasukwa yakachena mushure mekunatsa zvinokanganisa kubudirira kana kutadza kwekukura kwemasero. Shamba midziyo nemaoko mushure mekunatsa, uye mudziyo wega wega unofanira kudzokororwa "uzadzwe nemvura-usina chinhu" kanenge ka15, wozopedzisira wanyikwa mumvura yakanyungudutswa kaviri ka2-3, woomeswa kana kuomeswa, wozorongedzwa kuti uzoshandiswa gare gare.

Nzira yekuchenesa yekushandisa XPZmuchina wekuwachisa magirazi murabhoritarikuchenesa ndiro yepetri:
Huwandu hwekuchenesa: Ndiro dzepetri 168 dzinogona kucheneswa muchikamu chimwe chete
Nguva yekuchenesa: maminetsi makumi mana kuti upedze kuchenesa
Maitiro ekuchenesa: 1. Isa dhishi rePetri rinofanira kucheneswa (ritsva rinogona kuiswa zvakananga muwasher yemabhodhoro, uye dhishi rePetri rine culture medium rinofanira kudurura chidimbu chikuru checulture medium zvakanyanya sezvinobvira) mudengu rinoenderana newasher yemabhodhoro. Rutivi rumwe chete runogona kuchenesa ndiro dzePetri makumi mashanu nematanhatu, uye kamwe chete runogona kuchenesa ndiro dzePetri dzine three-layer zana nemakumi matanhatu nemasere.
2. Vhara gonhi remuchina wekuwachisa mabhodhoro, sarudza purogiramu yekuchenesa, uye muchina wacho unotanga kuchenesa wega. Maitiro ekuchenesa anosanganisira kuchenesa usati watanga - kuwachisa main alkali - neutralization acid - kusukurudza nemvura yakachena.
3. Mushure mekuchenesa, gonhi remuchina wekuwachisa mabhodhoro rinovhurwa roga, roburitsa ndiro yakacheneswa, roenda kumidziyo yekubvisa utachiona kuti riparadzwe.
Kucheneswa kwemidziyo yepetri mumarabhoritari ezvebhayoloji chikamu chakakosha chekutarisira marabhoritari. Kushandisa muchina wekuwachisa mabhodhoro unongoerekana wagadzirwa panzvimbo pekuchenesa nemaoko kunogona kudzivirira kusvibiswa kwakasiyana-siyana kubva pakukanganisa data rekuyedza, kuchengetedza hutano hwevashandi vekuyedza, uye kuvandudza kushanda zvakanaka kwekuyedza.
