Kuraho burundu umwanda wamavuta hejuru ya sima, sukura umucanga numukungugu, ubushuhe nibindi, kugirango urebe neza ko ubuso bworoshye, busukuye, bukomeye, bwumutse, butabira ifuro, ntabwo ari umucanga, nta guturika, nta mavuta.Ibirimo byamazi ntibigomba kuba hejuru ya 6%, agaciro ka pH ntabwo karenze 10. Urwego rwimbaraga za sima ya beto ntabwo iri munsi ya C20.
Ubushyuhe bwo hasi ntabwo buri munsi ya 5 ℃, kandi byibura 3 ℃ kurenza ubushyuhe bwikime cyikirere, ubuhehere bugereranije bugomba kuba munsi ya 85% (bigomba gupimwa hafi yibikoresho fatizo), igihu, imvura, shelegi, umuyaga n'imvura birabujijwe rwose kubaka.
1, Ubike ahantu h'umuyaga wa 25 ° C cyangwa ahantu hakonje kandi humye.Irinde urumuri rw'izuba, ubushyuhe bwinshi cyangwa ibidukikije byinshi.
2, Koresha vuba bishoboka mugihe ufunguye.Birabujijwe rwose guhumeka ikirere igihe kirekire nyuma yo gufungura kugirango birinde kugira ingaruka ku bicuruzwa.Ubuzima bwo kumara amezi atandatu mubushyuhe bwicyumba cya 25 ° C.
