Yuav Ua Li Cas Thiaj Cia Lub Thawv Roj Hmab
1.Txiav ntsuas kub
Lub tsev muag khoom kub yuav tsum qis dua +25 ºC, nws yuav tsum yog qhov tsaus dua thiab qis dua +15 ºC. Yog tias qhov kub siab tshaj 25 ºC lossis qis dua 0 ºC, cov khoom ntawm cov roj hmab yuav hloov pauv, yog li cuam tshuam qhov kawg kev pab cuam lub neej ntawm thetire. Cov chaw cia txias tsis muaj qhov cuam tshuam zoo rau cov khoom siv roj hmab.
2.Ntawm
Huab cua txaus ntshai heev yuav tsum zam. Cov av noo hauv chav cia khoom cua yuav tsum tsis txhob nyob siab heev tias cov hws tau tshwm sim ntawm lub log tsheb. Cov log tsheb yuav tsum tsis txhob cia nyob rau hauv qhov chaw uas lawv tau tiv nag, txaws, thiab lwm yam.
3. Cov me
Cov log tsheb yuav tsum muaj kev tiv thaiv los ntawm lub teeb, tshwj xeeb los ntawm kev tshav ntuj ncaj qha thiab muaj lub zog muaj hluav taws xob nrog cov ntsiab lus siab ultraviolet.
4.Oxygen thiab ozone
