Ukufafaza i-S-abscisic acid ngesikhathi sokuvuthwa kukakolweni nezigaba zokugcwalisa okusanhlamvu kukhulisa ngempumelelo isivuno futhi kuthuthukisa ikhwalithi. Izinzuzo zayo eziyinhloko zilele ekwandiseni isisindo sezinhlamvu eziyinkulungwane, ukukhulisa ikhwalithi yokusanhlamvu, nokuqinisa ukumelana nokucindezeleka; iyisilawuli sokukhula kwezitshalo esivame ukusetshenziswa ohlelweni "lwesifutho esisodwa, ukuvimbela okuthathu" (izinambuzane eziyinkimbinkimbi, izifo, nokulawula ukucindezeleka) kakolweni.
Ukuqinisekiswa kwemiphumela ethile ye-S-abscisic acid
Ukwandisa isisindo sokusanhlamvu okuyinkulungwane ukuze kukhuliswe isivuno
I-S-abscisic acid ivimbela ukukhula kwezitshalo ngokweqile (ukwelulwa kwesiqu namaqabunga), ngaleyo ndlela iqondise kabusha imisoco eyengeziwe ekugcwalisweni okusanhlamvu. Ngesikhathi esifanayo, ithuthukisa i-photosynthesis futhi isheshisa ukuhlanganiswa nokuqoqwa kwama-amino acid namaprotheni. Lokhu kukhuthaza ukukhula nokuthuthuka okugcwele okusanhlamvu, okwandisa kakhulu isisindo sezinhlamvu eziyinkulungwane. Idatha ibonisa ukuthi ukusetshenziswa okufanele kungakhuphula isisindo sezinhlamvu eziyinkulungwane ngamagremu angu-1-3, ekugcineni kubangele ukwanda kwesivuno ngo-5% -15%.
Ukuthuthukisa izinga likakolweni
I-S-abscisic acid ikhuthaza ukunqwabelana kwezinto ezomile—njengesitashi namaprotheni—ngaphakathi kokusanhlamvu. Iqinisekisa ukuthuthwa kwezakhi ezijwayelekile ngisho nangaphansi kwezimo zengcindezi njengesomiso noma amazinga okushisa aphezulu, inciphisa ingxenye yezinhlamvu ezishwabene noma ezingenalutho. Iphinde ithuthukise ukugcwala nokufana okusanhlamvu, ngaleyo ndlela kuthuthukise izinga lokucubungula; lokhu kuthuthukiswa kwekhwalithi kugqama kakhulu ezindaweni zokulima endaweni eyomile.
Ukuthuthukisa ukumelana nengcindezi nokunciphisa izingozi zokulahlekelwa isivuno
Izigaba zokuvuthwa kanye nokugcwaliswa okusanhlamvu yilapho ukolweni usengozini enkulu yokulimala ngenxa yemimoya eshisayo, eyomile kanye nesomiso. I-S-abscisic acid icupha izinhlelo zesitshalo zokubhekana nengcindezi, ikhulise ukumelana nomoya oshisayo, owomile, amazinga okushisa aphezulu, nesomiso. Yelula isikhathi sokusebenza kwamaqabunga, ivimbela ukuvuthwa ngaphambi kwesikhathi kanye nokuvuthwa okuphoqelelwe okubangelwa ukushisa, futhi iqinisekisa ukugcwaliswa okusanhlamvu okushelelayo-kunikeza ukusebenza okuphezulu kokumelana nokucindezeleka uma kuqhathaniswa nokusebenzisa i-brassinosteroids iyodwa. Izinkombandlela Zokusetshenziswa Ezijwayelekile
Kukolweni wasebusika, i-S-abscisic acid ivamise ukusetshenziswa "esifuthweni esisodwa, ukuvimbela okuthathu" (ukulawula okuphelele) kungxube yethangi. Imininingwane yohlelo lokusebenza imi kanje:
Umthamo: Ekubunjweni kuka-0.1%, izinga lokufaka isicelo lingama-40-50 amagremu mumu ngayinye. Uma ifuthwe iyodwa, isilinganiso esinconyiwe singamamililitha angama-20 ngemu ngayinye ekubunjweni kuka-0.1%, kuyilapho ukwakheka kuka-0.03% kufanele kuhlanjululwe ngokuphindwe ka-1,500 ngaphambi kokufafaza.
Ukuxutshwa Kwamathangi: Kuvamise ukuxutshwa nama-fungicides (njenge-pyraclostrobin), izibulala-zinambuzane (njenge-cypermethrin esebenza kahle kakhulu), kanye nezivundisi ze-foliar (njenge-potassium dihydrogen phosphate). Le ndlela ngesikhathi esisodwa ilawula izifo, izinambuzane, kanye nomonakalo ovela emoyeni owomile, oshisayo ngenkathi ithuthukisa isivuno nekhwalithi, iyenze ibe isu elijwayelekile lokufaka isicelo phakathi nezigaba zokuvuthwa kanye nokugcwaliswa okusanhlamvu.
