Ukukhishwa kwe-ethylene kusuka ku-i-ethephonIsixazululo asihlobene nje kuphela nenani le-pH, kodwa futhi sihlobene nezimo zemvelo zangaphandle njengokushisa, ukukhanya, umswakama, njll., ngakho-ke qiniseka ukuthi uyayinaka le nkinga esetshenziswayo.
(1) Inkinga yokushisa
Ukuqhekekai-ethephoniyanda ngokushisa okwandayo. Ngokusho kokuhlolwa, ngaphansi kwezimo ze-alkaline, i-ethephon ingabola ngokuphelele futhi ikhishwe emanzini abilayo imizuzu engama-40, kushiye ama-chloride nama-phosphate. Kuye kwafakazelwa ngomkhuba ukuthi umphumela we-ethephon ezitshalweni uhlobene nokushisa ngaleso sikhathi. Ngokuvamile, kuyadingeka ukugcina izinga lokushisa elifanele isikhathi esithile ngemva kokwelashwa ukuze kube nomphumela osobala, futhi ngaphakathi kwebanga elithile lokushisa, umphumela uyanda ngokwanda kwezinga lokushisa.
Ngokwesibonelo,i-ethephoninethonya elihle ekuvuthweni kwama-boll kakotini ekushiseni okungu-25 °C; 20~25 °C nayo inethonya elithile; ngaphansi kuka-20 °C, umphumela wokuvuthwa mubi kakhulu. Lokhu kungenxa yokuthi i-ethylene idinga izimo zokushisa ezifanele enkambisweni yokubamba iqhaza emisebenzini yezitshalo neye-biochemical. Ngesikhathi esifanayo, ngaphakathi kobubanzi obuthile bokushisa, inani le-ethephon elingena esitshalweni liyakhula ngokukhuphuka kokushisa. Ngaphezu kwalokho, izinga lokushisa eliphakeme lingasheshisa ukunyakaza kwe-ethephon esitshalweni. Ngakho-ke, izimo zokushisa ezifanele zingathuthukisa umphumela wokusetshenziswa kwe-ethephon.
(2) Izinkinga zokukhanyisa
Ukukhanya okuthile kungakhuthaza ukumuncwa nokusetshenziswa kwei-ethephonyizitshalo. Ngaphansi kwezimo zokukhanya, i-photosynthesis kanye nokuphefumulela kwezitshalo kuyaqiniswa, okusiza ekuholeni kwe-ethephon ngokuthuthwa kwezinto eziphilayo, futhi i-stomata yamaqabunga ivulekile ukuze kube lula ukungena kwe-ethephon emaqabunga. Ngakho-ke, izitshalo kufanele zisebenzise i-ethephon ezinsukwini ezinelanga. Kodwa-ke, uma ukukhanya kunamandla kakhulu, uketshezi lwe-ethephon olufuthwe emaqabungeni kulula ukuluma, okuzothinta ukumuncwa kwe-ethephon ngamaqabunga. Ngakho-ke, kubalulekile ukugwema ukufafaza ngaphansi kokukhanya okushisayo nokunamandla emini ehlobo.
(3) Umswakama womoya, umoya kanye nemvula
Umswakama womoya uzothinta nokumuncwa kwei-ethephonngezitshalo. Umswakama ophezulu akulula ukuthi uketshezi lome, okuyinto elula ukuthi i-ethephon ingene esitshalweni. Uma umswakama uphansi kakhulu, uketshezi luzoma ngokushesha ebusweni beqabunga, okuzothinta inani le-ethephon engena esitshalweni. . Kungcono ukufafaza i-ethephon ngomoya. Umoya unamandla, uketshezi luzohlakazeka nomoya, futhi ukusebenza kahle kokusetshenziswa kuphansi. Ngakho-ke, kubalulekile ukukhetha usuku olunelanga olunomoya omncane.
Akufanele kube nemvula zingakapheli amahora ayi-6 ngemuva kokufutha, ukuze kugwenywe ukuthi i-ethephon ikhukhulwe yimvula futhi ithinte ukusebenza kahle kwayo.
