1. Hunyoro hwemashizha.Nekuramba kuri kurasikirwa kwemvura yakachena yemashizha, huwandu hukuru hwezviri mukati mayo huchaora, hune oxidized uye kurasika, izvo zvinokanganisa kunaka kweti padiki diki, uye zvinozotungamira mukuipa kwefresh leaves uye kurasikirwa kwehupfumi mumatambudziko akaoma.Naizvozvo, kuitira kuchengetedza tii nyowani, nzira yekupfapfaidza inowanzogamuchirwa kuchengetedza nzvimbo yekuchengetera mashizha pahunyoro hwepamusoro.

2. Tembiricha.Kupisa kwekunze kunonyanya kukanganisa kufema kwemashizha matsva.Iyo yakakwira tembiricha, iyo yakasimba kufema kwemashizha matsva, uye nekukwirira kwekushisa kweshizha, kusimba kwekuita kwe enzyme, iyo isingaenderane nemhando yetii.Naizvozvo, tembiricha yakakodzera yakaderera inobatsira kuchengetedza kutsva kwemashizha etii.

3. Okisijeni.Kana kufefetera kuri kushomeka panguva yekuchengetera, iyo anaerobic kufema kwetii kuchawedzera enzyme chiitiko, kukurumidza kuparara kwe organic matter, uye kuwedzera oxidation ye polyphenols.Mukuita kwe hypoxia, mashizha matsva zvishoma nezvishoma anoburitsa kunhuwa kwakashata kana rancid kuvava kuravira, izvo zvinokanganisa kunhuhwirira kwekupedza tea.Naizvozvo, mukunhonga mashizha matsva, kutakura, uye chengetedzo yechinyakare Chinese mushonga, chengetedza kutenderera kwemhepo kudzivirira kufema kweanaerobic kwemashizha matsva uye kukanganisa kunaka kwetii.

4. Mechanicalkukuvara.Mushure mokunge mashizha matsva atambura nekukuvara kwemagetsi, kune rumwe rutivi, kufema kwemashizha matsva kunowedzera kusimba uye kupisa kwemashizha kunokwira nokukurumidza;kune rumwe rutivi, inokonzera enzymatic oxidation ye polyphenols, iyo inowanzoita mashizha tsvuku kuchinja.
