Nkhungu pazenera, komanso pamkati mwa makoma a nyumba ndi nyumba, zimapezeka chifukwa cha mvula yambiri mu chipinda. Chotsani bowa chochuluka mofulumira ndipo chiyenera kukhala, chifukwa nkhungu imafalikira mofulumira kwambiri. Kuphatikizanso apo, kukhalapo kwawo kumakhala kovulaza kwa anthu: nkhungu ikhoza kuyambitsa zotsatira zoopsa za matenda, matenda a khungu, kapweya wam'mwamba, ndi zina zotero.
Kodi kuchotsa nkhungu pamtunda wa mawindo apulasitiki?
Zindikirani kuti chifukwa cha nkhungu pazenera za pulasitiki zikuwonekera mochuluka. Chifukwa cha ichi ndi "cholakwika" microclimate cha chipinda chomwecho, kumene kulibe mpweya wokhala ndi mpweya wabwino kupyolera muzitsulo zazikulu, monga momwe zilili ndi mawindo a matabwa, koma pali kutentha kwakukulu (60% kapena kuposerapo).
Kulimbana ndi nkhungu ziyenera kukhala motere: pamwambapa zomwe zimakhudzidwa ndi bowa ayenera kuyamba kutsukidwa ndikuzitsatiridwa ndi mankhwala a chlorini. Zikhoza kukhala zapakhomo, zoyera, vitriol zamkuwa kapena antiti ("Risana", "Tiprom", "Sto"). Ngati palibe nkhungu zambiri, mukhoza kuyesa malo okhudzidwa ndi soda wamba, zomwe zimapangitsa kununkhira bwino, kapena ndi mankhwala oyenera a mtengo wa tiyi.
Kuposa kukonza nkhungu pazenera za matabwa?
Nthawi zina ndi bwino kuchotsa nkhungu ndi nkhuni. Pachifukwachi, amagwiritsira ntchito mabotolo, omwe amapezeka pamtunda pambuyo pochiza matendawa. "NEOMID", "Senezh INSA" amatanthauza kuti ndi otchuka. Ngati tikulankhula za woyera ndi hydrogen peroxide, ndiye kuti kuyanjana kwawo ndi nkhuni sikuli koyenera, chifukwa kumapangitsa kufotokoza kwakukulu kwa mafelemu a matabwa. Ponena za biocides - zimadzimadzimadzi - zimayenera kugwira ntchito mosamala, chifukwa zonse ndizoopsa.
