(1) Ukulinywa kweembotyi zesoya kunye nombona

Kummandla osemzantsi-ntshona, imvula ininzi, kwaye kukho iindidi ezininzi zokhula, ekunzima ukuzilawula.Umbona utyalwa phambi kokuba iimbotyi zesoya kwaye ukusetyenziswa kwemichiza yokutshabalalisa ukhula kufuneka “kubulawe ngokudibeneyo”.Emva kokuba umbona uhlwayelwe, sebenzisa i-metolachlor (okanye i-acetochlor) + i-thifensulfuron-methyl ukutywina umhlaba.Ukuba kukho ukhula entsimini ngaphambi kokuba umbona uhlwayelwe, ungasebenzisa i-glufosinate-ammonium spray;Isiphumo sokutywinwa komhlaba asilunganga Ukuba ngaba kuyafuneka unyango lokutshizwa kwesiqu kunye namagqabi, i-nicosulfuron + fluroxypyr (okanye i-clopyralid, i-bentazone) ingasetyenziselwa ukukhomba indlela (indawo yokutyala umbona) isiqu kunye nesitshizi samagqabi kwinqanaba le-3 ukuya kwele-5 emva kwezithole zombona.

Kwiintsuku ezintathu phambi kokuhlwayelwa kweembotyi zesoya, kwakhethwa iglufosinate ukuze kutshizwe ngendlela eyalathiswayo kwimiqolo engenanto entsimini.Emva kokuhlwayela naphambi kwezithole, umhlaba uvalwe nge-pesticides ezifana ne-metolachlor (okanye i-acetochlor) + thifensulfuron-methyl.Ukuba isiphumo sokutywinwa komhlaba asifanelekanga kwaye ukutshizwa kweziqu kunye namagqabi kuyafuneka, i-quizalofop-pp (okanye i-high-efficiency fluroxyfop-pp, fluazifop-pp, clethodim) + B Carboxyfluorfen (okanye i-bentazone) ekujoliswe kuyo (indawo yokutyala iimbotyi zesoya) isiqu kunye isitshizi samagqabi.

(2) Ukulinywa kweembotyi zesoya kunye nombona

E-Huanghuaihai, indawo ephakathi kunye nesezantsi yoMlambo waseYangtze, kunye neNyakatho-ntshona yeChina, iimbotyi zesoya kunye nombona zihlwayelwa ngexesha elifanayo, kwaye i-herbicides isetyenziswa kakhulu emva kokuhlwayela kunye nonyango lokutywinwa komhlaba kwangaphambili, olufunekayo ukuba lugqitywe ngaphakathi kwe-2. iintsuku emva kokuhlwayela.Ukutywinwa komhlaba kuqhutyelwa ngokusebenzisa i-metolachlor ecocekileyo (okanye i-metolachlor, i-acetochlor) + i-fensulfame (okanye i-thifensulfuron-methyl) kunye nezinye ii-agent.Xa umhlaba uvalwe ngemichiza yokutshabalalisa ukhula entsimini apho iindiza zangaphambili ziyingqolowa, kungcono ukulima ngokujikelezayo ukususa iindiza, ukudala ukufuma, kwaye emva koko kuhlwayelwe kwaye kugalelwe izitshabalalisi phambi kokutyala;kumasimi apho iindiza zengqolowa zisasazwa ngokuthe ngqo, kuyafuneka ukwandisa usetyenziso lwamanzi ngemumu nganye, kwaye kugalelwe nemichiza yokutshabalalisa izinambuzane ukuba kuyenzeka.Emva koko, amanzi ngexesha;kwiindawo ezinembalela kunye nezivunguvungu zesanti ezifana noMntla-ntshona, kungcono ukuxuba umhlaba emva kokusetyenziswa kwe-herbicides, kunye namanzi ngexesha apho iimeko zivuma.

Xa isiphumo sokutywinwa komhlaba singafanelekanga kwaye unyango lokutshizwa kwesiqu kunye namagqabi luyafuneka, lunokusetyenziswa kwinqanaba lama-3-5 amagqabi emva kwezithole zombona, iimbotyi zesoya ezi-2-3 kwinqanaba lamagqabi amathathu, kunye nokhula kwi-2-5 isigaba samagqabi.Ngokweemeko zengca yendawo, umbona unokukhethwa.I-Nicosulfuron (okanye i-oxaflumezone) + i-bentazone (okanye i-fluroxypyr), kunye namasimi eembotyi zesoya akhetha i-quizalofop-p-ethyl (okanye i-fluroxyfop ephezulu) + i-bentazone (okanye i-fluroxyfen-ethanol) ) Ukutshiza ngendlela ye-Stem-leaf directional ukuhlakula (sebenzisa amakhethini omzimba ukwahlula umbona kunye neembotyi zesoya zokutshiza).Kwinqanaba lamva, ukhula okunzima ukululawula lunokususwa ngesandla.
