Zaukadaulo zitha kugwiritsidwa ntchito kupanga chinthu kapena kusakaniza mumankhwala, ndipo zimakhala zogwira ntchito muzamankhwala popanga mankhwala.Zikafika mankhwala ophera tizilombo, mawu odziwika bwino samakonzedwa.Zipangizo zaukadaulo zimagawidwanso m'njira zosiyanasiyana, monga zida zaukadaulo zolimba zimatchedwa ufa waiwisi, ndipo zida zaukadaulo zamadzimadzi zimatchedwa mafuta osakhwima.Monga momwe mankhwala ophera tizilombo amatha kugawidwa kukhala olimba ndi madzi, palinso ufa wonyowa, ma granules ndi zina zotero.
Kholo mankhwala amatanthauza osakaniza akamagwira Kutha yogwira zosakaniza ndi mkulu okhutira ndi zosungunulira.Kawirikawiri, tinganene kuti mankhwala ophera tizilombo amapangidwa kuchokera ku mankhwala oyambirira, koma ndi osiyana ndi kukonzekera mankhwala ophera tizilombo.
Luso zakuthupi ndi kholo mankhwala angagwiritsidwe ntchito ngati zopangira pokonzekera kukonzekera, koma si oyenera ntchito mwachindunji mbewu minda.Nthawi zambiri timagwiritsa ntchito mankhwala ophera tizilombo omwe akonzedwa.
Popeza kuchuluka kwa zinthu zaukadaulo ndikwambiri ndipo sikunasinthidwe, ndikwabwinoko komanso kothandiza?
Yankho ndi mphamvu ya ntchito mwachindunji zipangizo luso ndi otsika, kuipitsa waukulu, ndipo pangakhale mavuto chitetezo ndi kuvulaza mankhwala.
Zambiri mwazinthu zamakono sizisungunuka mwachindunji m'madzi, choncho ziyenera kukonzedwa.Mankhwala ophera tizirombo ndi herbicides omwe timagula nthawi zambiri ndi mankhwala okonzekera pambuyo pokonza.
Zokonzekera zambiri zimachokera ku zipangizo zamakono, ndikuwonjezera zowonjezera zina, monga surfactants, zipangizo zamakono, zosungunulira, etc.
Ngati sichinapangidwe kuti chikonzekere, kuchuluka kwa kagwiritsidwe ntchito ka mankhwala ophera tizilombo kumakhala kochepa, ndipo kubalalitsidwa kwake sikwabwino kwambiri, zomwe zimatha kuyambitsa kuwonongeka kwa chilengedwe ndi zovuta zachitetezo.
Ndipo zipangizo zamakono ndi za kawopsedwe kwambiri, ndipo zimakhala mankhwala ophera tizilombo toyambitsa matenda pambuyo pokonzekera, zomwe zimachepetsa kuwonongeka kwa thupi la munthu.
Tikamagwiritsa ntchito mankhwala, cholinga chachikulu ndikuteteza matenda, tizirombo ndi udzu.Kuti tikwaniritse cholingachi, sichidzawononga mbewu, choncho tiyenera kulabadira:
① Kuti mugwiritse ntchito molingana ndi malangizo a mankhwala ophera tizilombo, musawonjezere mlingo mosavuta.
② Osapoperanso kupopera mankhwala kuti asawonongeke.
③ Ndi bwino kugwiritsa ntchito mankhwala ophera tizilombo nyengo yopanda mphepo kuti muchepetse kutengeka kwa mankhwala ophera tizilombo.
