I-molecular oxygen inyibilikiswa emanzini ibizwa ngokuba yi-oksijini enyibilikileyo kwaye idla ngokuphawulwa njenge-D0. Ubungakanani beoksijini enyibilikisiweyo kumanzi angaphezulu ngu-5-10mg/L. Xa kukho imimoya enamandla namaza, ioksijini enyibilikisiweyo emanzini inokufikelela kwi-14mg/L. I-oksijeni echithiweyo i-oxygen saturation = i-oksijini echithiweyo Ixabiso elilinganisiweyo / umxholo wokugcwalisa i-oksijini echithwe phantsi kweemeko ezilinganisiweyo * 100%, oko kukuthi, i-90% nangaphezulu, ixabiso elilinganisiweyo lingaphezulu kwe-7.5mg / L, kwaye ubuncinci yi-2mg / L.
Amanzi aphantsi-oksijini aya kuhamba ngesityalo kwaye asuse i-oksijini kwi-root system, kwaye ngokufanayo, iya kuphelisa i-oksijeni emhlabeni. Zombini isityalo esisempilweni kunye nezityalo zomhlaba osempilweni zidinga ioksijini kula macandelo mabini.
Ukungabikho kweoksijini enyibilikayo emanzini kunokubangela ezinye iingxaki. Ngokomzekelo, i-nematodes ifana nomhlaba we-anoxic. Ukunkcenkceshela izityalo ngamanzi e-oksijini ephantsi kuya kubangela ukuba basondele kumphezulu kwaye zonakalise ngokulula iingcambu zezityalo.
Uphononongo lubonise ukuba ukunciphisa ukuxinana kweoksijini enyibilikisiweyo kwindawo yengcambu yesityalo kuya kunciphisa isakhono sesityalo sokufunxa initrogen namanzi. Ukungabikho kweoksijini kunokwenzakalisa iingcambu. Ngethuba lokuziqhelanisa nokugxininiswa okuphantsi kwe-oksijeni echithwe, i-metabolism yesityalo iyatshintsha. Ukungabikho kweoksijini ngaphakathi kwesityalo kubizwa ngokuba yi-hypoxia yangaphakathi. Esinye seziphumo kukuba i-sucrose iyancipha, kwaye izityalo zihambela kwiindlela zokonga amandla ukubuyisela ukungabikho komoya.
I-photosynthesis ye-phytoplankton ngumthombo oyintloko we-oksijini echibini, ngokuqhelekileyo ibala i-56% -80% yomthombo we-oksijini; enye iphuma kumaza avuthuza ngumoya ukuze ioksijini esemoyeni inyibilike ngokuthe ngqo emanzini. I-Advantageous 12-14mg/L
I-Heilongjiang: Ummandla oziimitha ezingama-600 ze-basking pool uya kuphucula ubushushu bamanzi nge-3 ukuya kwi-4 degrees kwaye yonyuse imveliso yeenkozo nge-6%.
