Kwisicwangciso esenziwe eTshayina 2025, ukwenziwa ngobukrelekrele yeyona nto iphambili kunye nomxholo ophambili wophuhliso lwexesha elizayo loshishino lokuvelisa, kunye nendlela esisiseko yokusombulula ingxaki yoshishino lwemveliso yaseTshayina ukusuka kwilizwe elikhulu ukuya kwilizwe elinamandla.
Kwiminyaka yoo-1970 kunye no-1980, iifektri zokulungiselela zase-China zazinoxanduva lokupakishwa okulula kwezibulali-zinambuzane kunye nokusetyenzwa kwe-emulsifiable concentrate, i-ejenti yamanzi kunye nomgubo.Namhlanje, ishishini lokulungiselela laseTshayina ligqibe ulwahlulo kunye nokhethekileyo kwishishini lokulungiselela.Ngeminyaka yee-1980, ukuveliswa kwamalungiselelo okubulala izitshabalalisi kwangenisa incopho yenkqubo kunye nophuculo oluzenzekelayo.Isikhokelo sophando kunye nophuhliso lolungiselelo lwesitshabalalisi sijolise kwimisebenzi yebhayoloji, ukhuseleko, ugcino lwabasebenzi kunye nokunciphisa ukungcoliseka kwendalo.Ukukhethwa kwezixhobo kufuneka kudityaniswe nesikhokelo sophando kunye nophuhliso lolungiselelo lwesitshabalalisi, kwaye kuhlangatyezwane nale migaqo ilandelayo: ① iimfuno zomgangatho wemveliso;② iimfuno zokhuseleko lokusingqongileyo;③ iimfuno zokhuseleko;④ inkonzo emva kwentengiso.Ukongezelela, ukukhethwa kwezixhobo kufuneka kwakhona kuthathelwe ingqalelo kwiinkalo zeyunithi yokusebenza kweyunithi yokulungiswa kwemveliso kunye nezixhobo eziphambili zokulungiselela.Khokela bonke abasebenzi ukuba bathathe inxaxheba kwingxoxo yokukhethwa kwezixhobo, kwaye uzame ukwenza ukhetho lwezixhobo kwisinyathelo esinye.
Xa kuthelekiswa nokuveliswa kwemveli, umgca wokuvelisa ngokuzenzekelayo ubonakaliswe ngokuqondakalayo kunye nokucwangciswa.Ekusetyenzisweni kwenkqubo yolawulo lweyunithi, ingqwalasela eyodwa kufuneka ihlawulwe: ① ukunyangwa kwangaphambili kwemathiriyeli ekrwada kunye neyokuncedisa;② i-acid-base neutralization reaction, i-alkali yotywala yokulawula ubunzima kunye nenkqubo yokulawula ukuhamba;③ Ulawulo lwenqanaba lolwelo oluphezulu kunye noluphantsi kunye nokulawulwa kobunzima bokugcwalisa kunye ne-batching tank.
Kukho iindawo ezintlanu ezingundoqo kwinkqubo yolawulo ehlanganisiweyo yomgca wokuvelisa i-lil yesityalo glufosinate: ① inkqubo yolawulo lokusasazwa kwezinto ekrwada;② inkqubo yokulawula ukulungiswa kwemveliso;③ uthutho olugqityiweyo lwemveliso kunye nenkqubo yokuhambisa;④ umgca wemveliso wokuzalisa ngokuzenzekelayo;⑤ inkqubo yolawulo lwendawo yokugcina impahla.
Umgca wokuvelisa okrelekrele awunakuhlangabezana neemfuno zokuqhubekeka nokuzenzekela ngokulungiswa kwe-pesticide, kodwa nokwenza amashishini aphendule ngokukhawuleza.Yeyona ndlela yodwa yoshishino lokulungiselela.Ingqikelelo yayo yoyilo yile: ① ukuhambisa imathiriyeli evaliweyo;② ukucoca i-CIP kwi-intanethi;③ utshintsho olukhawulezayo lwemveliso;④ ukurisayikilisha.
