Zinc ndi gawo lofunikira pakusunga kukula kwa mitengo yazipatso. Mu mitengo yazipatso chobzala, kugwiritsa ntchito zinc sulfate sikungochepetsa zofooka za zipatso, komanso zimachulukitsa zipatso za zipatso.
Zizindikiro za kuperewera kwa zinc mumitengo yazipatso: Mitengo yopanda zipatso nthawi zambiri imakhala yofupikirapo ma ratus, masamba ochepa, maluwa ochepa, osavuta kufooka, ngakhale kufa Mtengo wonse.
Pamene zaka ndi zipatso za mitengo yazipatso zimachuluka, makamaka mitengo yamchenga ya zipatso, makamaka mainchesi amchenga, maiko a saline-alkali ndi zipatso zochulukitsa.
Kuthana ndi zizindikiro za kuperewera kwa zinc kuchepa mu mitengo yazipatso, njira zotsatirazi zingatengedwe:
1. Ikani feteleza wa zin ku dothi. Kuphatikizidwa ndi kugwiritsa ntchito feteleza wa base ndi feteleza, nthawi zambiri 100-200 magalamu mtengo kwa mitengo yazipatso yomwe ili ndi mitengo yazipatso, ndi 250-300 magalamu pamtengo uliwonse kapena pamwambapa.
2. Spray zinc sulfate kunja kwa mizu. Mitengo yazipatso isanafike, utsi wa 1 ~ 5% zinc sulfate solution pamtengo wonse, utsi wa spray 0.1 ~ ~% zinc sulfate pambuyo pa masamba atatuwo kuti mukwaniritse zotsatira zabwino.
3. Chiwerengero chaichi ndi zinc sulfate: Flylime: Madzi = 1: 2: 240, ndipo njira yosinthira ndi bordeaux.
