(1) Ukulinywa kwebhanti kwimbotyi yesoya kunye nombona

Emazantsi-ntshona eTshayina, kukho imvula eninzi, iintlobo ezininzi zokhula, kwaye kunzima ukuzilawula.Umbona uhlwayelwa phambi kweembotyi zesoya, kwaye ukusetyenziswa kwemichiza yokutshabalalisa ukhula kufuneka "kutywinwe kwaye kuhlanganiswe".Emva kokuhlwayela naphambi kwezithole, umhlaba uya kutywinwa nge-metolachlor (okanye i-acetochlor)+thiofensulfuron methyl kunye nezinye ii-agent.Ukuba kukho ukhula entsimini phambi kokutyala, intsimi inokutshizwa ngesitshizi se-glyphosate;Ukuba isiphumo sokutywinwa komhlaba asifanelekanga kwaye unyango lokutshizwa kwesiqu kunye neqabunga luyafuneka, i-nicosulfuron methyl+chlorofluoropyranoxyacetic acid (okanye i-dichloropyridic acid, methimaxone) ingasetyenziselwa ukwalathisa isiqu kunye nesitshizi samagqabi (kwindawo yokutyala umbona) kwindawo yesithathu. ukuya kwisigaba sesihlanu samagqabi kwizithole zombona.

Kwiintsuku ezintathu phambi kokuhlwayelwa kweembotyi zesoya, isitshizi esisiyaleleyo se-glyphosate sasisenziwa entsimini.Emva kokuhlwayela, phambi kokuba kutyalwe izithole, amayeza okubulala izitshabalalisi afana nepromethazine (okanye i-acetochlor)+thiophensulfron ikhethwa kunyango lokutywinwa komhlaba.Ukuba isiphumo sokutywinwa komhlaba asifanelekanga kwaye sidinga ukunyangwa ngesitshizi sesiqu kunye namagqabi, iquinclovir

(2) Ukulinywa kwebhanti kwimbotyi yesoya kunye nombona

KuMlambo oMthubi, uMlambo i-Huaihai, indawo ephakathi kunye nesezantsi yoMlambo waseYangtze, kunye nemimandla yasemntla-ntshona, iimbotyi zesoya kunye nombona zihlwayelwa ngaxeshanye.Ukusetyenziswa kweimichiza yokutshabalalisa ukhula isekelwe ikakhulu kunyango lokutywinwa komhlaba phambi kwezithole emva kokuhlwayela, ekufuneka igqitywe kwiintsuku ezi-2 emva kokuhlwayela.Umhlaba uvalwe ngee-agent ezifana ne-promethamide (okanye i-metolachlor, i-acetochlor)+azosulfochlor (okanye i-thiophenuron).Xa umhlaba okwintsimi apho isityalo sangaphambili sasiyingqolowa uvalwe ngemichiza yokutshabalalisa ukhula, kungcono ukulima nge-rotary tillage ukususa iindiza, ukudala ukufuma, kwaye emva koko kulinywe kwaye kugalelwe umchiza wokutshabalalisa ukhula phambi kokutyala;Kwintsimi yembewu ethe ngqo enezikhondo zengqolowa, kuyafuneka ukwandisa usetyenziso lwamanzi ngemumu nganye, kwaye ukuba iimeko zivuma, ukunkcenkceshelwa ngexesha elifanelekileyo kufuneka kuqhutywe emva kokufakwa kweizibulali zinambuzane;Kwiindawo ezomileyo nezinomoya ezifana nomntla-ntshona, kungcono ukuxuba umhlaba emva kokufakaimichiza yokutshabalalisa ukhula, kunye neendawo zamanzi ngexesha elifanelekileyo apho iimeko zivuma.

Xa isiphumo sokutywinwa komhlaba singafanelekanga kwaye unyango lokutshizwa kwesiqu lufuneka, lunokusetyenziswa kwisigaba esi-3 ~ 5 samagqabi emva kwezithole zombona, inqanaba le-2 ~ 3 lamagqabi embotyi yesoya, inqanaba le-2 ~ 5 lamagqabi okhula. .Ngokweemeko zengca yendawo, i-nicosulfuron (okanye i-oxazolone)+bentazone (okanye i-cloflupyroxyacetic acid) Kwintsimi yeembotyi zesoya, iquinoxal (okanye ukusebenza kakuhle okuphezulu kwe-flumetafop-p-ethyl)+dimethasone (okanye i-ethyl flumetafop-ethyl) isetyenziselwa isiqu kunye negqabi. i-directional spray spraying (amakhethini omzimba asetyenziselwa ukwahlula umbona kunye neembotyi zesoya).Kwinqanaba lamva, ukhula ekunzima ukululawula lunokususwa ngesandla.
