Ukukhululwa kwe-ethylene kusukai-ethephonIsixazululo asihlobene nje kuphela nenani le-pH, kodwa futhi sihlobene nezimo zemvelo zangaphandle ezifana nezinga lokushisa, ukukhanya, umswakama, njll., ngakho-ke qiniseka ukuthi uyayinaka le nkinga esetshenziswayo.
(1) Inkinga yezinga lokushisa
Ukubola kwei-ethephoninyuka ngokukhuphuka kwezinga lokushisa.Ngokusho kokuhlolwa, ngaphansi kwezimo ze-alkali, i-ethephon ingabola ngokuphelele futhi ikhishwe emanzini abilayo imizuzu engu-40, ishiye ama-chloride nama-phosphates.Kuye kwafakazelwa ngokwenza ukuthi umphumela we-ethephon ezitshalweni uhlobene nezinga lokushisa ngaleso sikhathi.Ngokuvamile, kuyadingeka ukugcina izinga lokushisa elifanele isikhathi esithile emva kokwelashwa ukuze kube nomphumela osobala, futhi ngaphakathi kwebanga elithile lokushisa, umphumela uyanda ngokunyuka kwezinga lokushisa.
Ngokwesibonelo,i-ethephoninomphumela omuhle ekuvuthweni kwamabholi kakotini ekushiseni okungama-25 °C;20~25 °C futhi kunomphumela othile;ngaphansi kuka-20 °C, umphumela wokuvuthwa mubi kakhulu.Lokhu kungenxa yokuthi i-ethylene idinga izimo zokushisa ezifanele ohlelweni lokubamba iqhaza emisebenzini yezitshalo ye-physiological and biochemical.Ngesikhathi esifanayo, phakathi kwebanga elithile lokushisa, inani le-ethephon elingena esitshalweni liyakhula ngokunyuka kwezinga lokushisa.Ngaphezu kwalokho, izinga lokushisa eliphakeme lingasheshisa ukunyakaza kwe-ethephon esitshalweni.Ngakho-ke, izimo zokushisa ezifanele zingathuthukisa umphumela wohlelo lwe-ethephon.
(2) Izinkinga zokukhanyisa
Ukuqina okuthile kokukhanya kungakhuthaza ukumuncwa kanye nokusetshenziswa kwei-ethephonngezitshalo.Ngaphansi kwezimo ezikhanyayo, i-photosynthesis kanye nokuphefumula kwezitshalo kuyaqiniswa, okwenza kube lula ukuqhutshwa kwe-ethephon ngokuthuthwa kwezinto eziphilayo, futhi i-stomata yamaqabunga ivulekile ukwenza lula ukungena kwe-ethephon emaqabunga.Ngakho-ke, izitshalo kufanele zisebenzise i-ethephon ezinsukwini ezinelanga.Kodwa-ke, uma ukukhanya kunamandla kakhulu, uketshezi lwe-ethephon olufuthwe emaqabunga kulula ukomisa, okuzothinta ukumuncwa kwe-ethephon ngamaqabunga.Ngakho-ke, kuyadingeka ukugwema ukufafaza ngaphansi kokukhanya okushisayo nokunamandla emini ehlobo.
(3) Umswakama womoya, umoya kanye nemvula
Umswakama womoya uzophinde uthinte ukumuncwa kwei-ethephonngezitshalo.Umswakama ophezulu akulula ukuthi uketshezi lome, okulungele ukuthi i-ethephon ingene esitshalweni.Uma umswakama uphansi kakhulu, uketshezi luzokoma ngokushesha endaweni yamaqabunga, okuzothinta inani le-ethephon engena esitshalweni..Kungcono ukufafaza i-ethephon ngomoya ohelezayo.Umoya unamandla, uketshezi luzohlakazwa nomoya, futhi ukusebenza kahle kokusetshenziswa kuphansi.Ngakho-ke, kuyadingeka ukukhetha usuku olushisayo olunomoya omncane.
Akufanele kube nemvula phakathi namahora angu-6 ngemva kokufafaza, ukuze kugwenywe ukuguguleka kwe-ethephon ngenxa yemvula futhi kuphazamise ukusebenza kahle kwayo.
