I-Prohexadione calcium isetshenziswa ngesikhathi sokwelulwa komoba, ngokuyinhloko ngokuvimbela ukwelulwa kwesiqu ngokweqile, ukuqinisa ukumelana nendawo yokuhlala, kanye nokugqugquzela ukudluliselwa kwezakhi ezihlahleni zomoba, ngaleyo ndlela kuzuzwe umphumela wokulawula ukuphakama kanye nokwanda kwesivuno.
Imiphumela eyinhloko ye-Prohexadione calcium:
1. Ivimbela ukwelulwa kwesiqu futhi yenza ama-internode abe mfishane: I-Prohexadione calcium iphazamisa ngokuphumelelayo ukwakheka kwe-gibberellin kumoba, ivimbele ukunwebeka ngokweqile kwama-internode phakathi nesigaba sokwelulwa, ilawula ukuphakama kwesitshalo, yenza iziqu zibe ukuqina futhi ziqine, futhi inciphisa ngokuphawulekayo ingozi yokulala.
2. Ithuthukisa ukumelana nendawo yokuhlala: Ngokufinyeza ubude bama-basal internode nokwandisa ukujiya nokugoba kwezindonga ze-internode, i-Prohexadione calcium ithuthukisa ngokuphawulekayo ukumelana nendawo yokulala yomoba, ikakhulukazi ezindaweni ezivame ukuba nomoya onamandla nemvula enamandla noma ngaphansi kwezimo eziphakeme zikamanyolo namanzi.
3. Ikhuthaza ukudluliselwa komsoco ezihlahleni zomoba futhi ikhulise isivuno: Nakuba ivimbela ukukhula kwezitshalo, i-Prohexadione calcium ikhuthaza ukunqwabelana kwemikhiqizo ye-photosynthetic ezinhlangeni zomoba, ikhulise okuqukethwe kwe-sucrose nokunqwabelana kwento eyomile, ngaleyo ndlela ithuthukise isivuno nekhwalithi.
4. Ithuthukisa isimo sokuphila kwezitshalo: I-Prohexadione calcium ingakhuphula okuqukethwe kwe-chlorophyll emaqabunga futhi ithuthukise ukusebenza kahle kwe-photosynthetic; iphinde ikhuthaze ukukhula kwezimpande, ibambezele ukubukeka kwezimpande ezigabeni zakamuva, futhi igcine isitshalo sinempilo.
Izincomo zohlelo lokusebenza:
Isikhathi sokufaka isicelo: Kunconywa ukuthi ufake isifutho se-foliar ngesikhathi sokuqala sobude bomoba (izinsuku ezingu-5-10 ngemva kokuqala kokwelula). Leli iwindi elibalulekile lokulawula ukukhula ngokweqile; ukufaka isicelo sekwephuzile kakhulu kuzonciphisa umphumela.
Umthamo onconyiwe: Bheka izindinganiso zokusetshenziswa kwezitshalo ezifana nerayisi. Sebenzisa amagremu angu-3-6 esithako esisebenzayo ku-667 m² (cishe 1 mu) (inani elithile lidinga ukulungiswa ngokuya ngokugxila komkhiqizo nokukhula kwesitshalo), lihlanjululwe ngamanzi futhi lifuthwe ngokulinganayo eziqwini nasemaqabungeni.
Izinyathelo zokuqapha: I-Prohexadione calcium iwohloka ngokushesha futhi inensalela encane, iyenze iphephe ezitshalweni ezilandelayo, kodwa kufanele igwenywe ukuxubana nezibulala-zinambuzane ezinamandla ezine-asidi. Uma imvula enkulu iba ngemva kokufakwa, ukufafazwa okwengeziwe kungase kudingeke.
