I-DCPTA ikhuthaza ngempumelelo ukulinywa kanye nokwakheka kwezikhwebu ebhali, kwenyusa isisindo sokusanhlamvu okuyinkulungwane, futhi kuthuthukise ikhwalithi yokusanhlamvu. Iwumlawuli wokukhula kwezitshalo ophephile futhi osebenza kahle kakhulu ofanele ukulawula ukukhula kwebhali kuwo wonke umjikelezo wayo wokuthuthuka.
Indlela Yesenzo kanye Nemiphumela Eyinhloko
1. Ukukhuthaza Ukulinywa Nokubunjwa Kwendlebe: Ngokuvula ukuvezwa kwezakhi zofuzo ezihlobene nokuhlukaniswa kwamaseli, i-DCPTA inyusa kakhulu inani lamathila kanye nezinga elisebenzayo lokuthwala izindlebe kubhali. Uma isetshenziswa ngesifutho se-foliar ngesikhathi sokuhlangana kwasekuqaleni, ithuthukisa ubungqabavu be-basal stem internodes, ikhuthaze amathila asendaweni ephansi ukuthi athuthuke abe izindlebe ezisebenzayo; lokhu kungaholela ekwenyukeni kwezinga lokuthwala izindlebe elingaphezu kuka-15%.
2. Ukwenyuka Kwesisindo Sokusanhlamvu Okuyinkulungwane: I-DCPTA ikhuphula izinga le-photosynthetic leqabunga lefulegi, ilibazise ukuhluma kwamaqabunga, futhi inwebe isikhathi sokugcwalisa okusanhlamvu. Ngasikhathi sinye, kusiza ukuhanjiswa kwama-carbohydrate ezinhlamvini, kuthuthukisa kakhulu ukugcwala okusanhlamvu kanye nesisindo sezinhlamvu eziyinkulungwane; idatha yesilingo ikhombisa ukukhula kwesisindo kusuka ku-8% kuya ku-12%.
3. Ukuthuthukisa Ikhwalithi: Ngokulandela ukusetshenziswa kwe-DCPTA, okuqukethwe kwezingxenye zokudla okunomsoco—njengamaprotheni kanye ne-β-glucan—ngaphakathi kwezinhlamvu zebhali kuyenyuka. Ngasikhathi sinye, izinga le-chalkiness (izikhwebu ezingacacile) liyehla, ngaleyo ndlela kuthuthukisa kakhulu ukudayiswa kwesitshalo.
Ukuthuthukisa Ukumelana Nengcindezi: Ngaphansi kwezimo zezinga lokushisa eliphansi noma ingcindezi yesomiso, i-DCPTA isiza ukugcina ibhalansi yamanzi esitshalo futhi ikhuphule umsebenzi wama-enzyme e-antioxidant (njenge-SOD ne-POD). Lokhu kunciphisa ukulimala kwe-oxidative futhi kusiza ukuqinisekisa isivuno esizinzile.
Iphrothokholi Yesicelo Enconyiwe
Isikhathi Esifanelekile: Faka isicelo ngesifutho se-foliar kanye ngesikhathi *sesiteji sokulima* futhi kanye phakathi *nesigaba sokuqalwa* ukuze ukwandise ukugqugquzelwa kokwakheka kwezikhwebu nokukhula kokusanhlamvu.
Ukugxiliswa Kwesicelo: Isilinganiso esinconywayo sokufafaza ngamaqabunga ngu-*20–30 mg/L** (noma ppm); gwema ukweqa ama-50 mg/L, njengoba lokhu kungase kuholele ekuvimbeleni ukukhula.
Iziphakamiso Zokuxuba Amathangi: Ukuze uthole imiphumela ethuthukisiwe, i-DCPTA ingaxutshwa futhi ifuthwe kanye no-0.2% we-monopotassium phosphate noma ngomanyolo we-micronutrient oqukethe i-zinc ne-boron. Le nhlanganisela ye-synergistic ithuthukisa ukusebenza kahle kwe-photosynthetic kanye nokuthathwa kwezakhi.
Ukuphepha:I-DCPTA ayinabo ubuthi futhi ayishiyi izinsalela eziyingozi; ihambisana nemvelo futhi iphephile kubantu nasezilwaneni. Iyahambisana nama-fungicides amaningi kanye nezibulala-zinambuzane, ngaleyo ndlela ithuthukise ukusebenza kahle.
