Esi sicwangciso solawulo lweekhemikhali sisebenzisa i-Mepiquat chloride yenzelwe inqanaba leentyantyambo eziphakamileyo zekotoni, ezijolise ekupheliseni amaqabunga angenamveliso, ukwandisa ubunzima be-boll, kunye nokukhuthaza ukukhula kwangaphambili.
1. IProtokholi yeSicelo se-Core Mepiquat Chloride
Faka i-12-16 ml ye-25% ye-Mepiquat chloride isisombululo se-aqueous (okanye i-3-4 g ye-technical-grade Mepiquat chloride) nge-mu, ehlanjululwe kwi-40-50 kg yamanzi. Sitshiza sonke isityalo ngokulinganayo, ugxininise kwisiqu esingundoqo kunye neengcebiso zamasebe avelisa iziqhamo. Kwimihlaba yekotoni ngokukhula okunamandla, umthamo unokunyuswa ukuya kwi-18 ml /mu; kumasimi anokukhula okubuthathaka, kufuneka kuncitshiswe ukuya kwi-10 ml/acre.
2. Imisebenzi ephambili yeMepiquat Chloride
Ukusetyenziswa kuthintela ukukhula kwamasebe exesha lasemva kwexesha elingavelisi mveliso, amagqabi, kunye nezihluma zezityalo, ngaloo ndlela kuncitshiswa inkunkuma yezondlo kunye nokukhuthaza ukufuduswa kwephotosynthates kwiibholi zomqhaphu. Oku kubangela ukunyuka kwesisindo sebholi enye ye-0.2-0.9 g, ukunciphisa ixesha lokuphuhlisa ibholi ngeentsuku ezi-1-2, ukuvulwa kwebholi ngokukhawuleza kunye nokugxininiswa, kunye nokwanda okukhulu kwinani le "cotton pre-frost" (umqhaphu ophezulu ovunwe ngaphambi kweqabaka yokuqala).
3. Imiqathango eyongezelelweyo
Tshiza emva kwemini enelanga; ukuba imvula ibakho kwiiyure ezi-4 zokufakwa kwesicelo, isitshizi kwakhona siyafuneka. Unyango lunokudityaniswa nesitshizi se-foliar se-0.2%–0.3% ye-potassium dihydrogen phosphate ukunyusa ngakumbi iziphumo zokunyusa ubunzima bebholi kunye nokukhuthaza ukukhula kwangoko.
