Empilweni yansuku zonke, i-ethephon ivame ukusetshenziselwa ukuvuthwa kukabhanana, utamatisi, ama-persimmon nezinye izithelo, kodwa yimiphi imisebenzi ethile ye-ethephon? Ungayisebenzisa kanjani kahle?
I-Ethephon, efana ne-ethylene, ithuthukisa kakhulu ikhono lokwakheka kwe-ribonucleic acid emaseli futhi ikhuthaza ukwakheka kwamaprotheni. Endaweni yokuphuma kwezitshalo, njenge-petioles, iziqu zezithelo, kanye nesisekelo samacembe, ngenxa yokwanda kokwakheka kwamaprotheni, ukwenziwa kabusha kwe-cellulase kungqimba lokuphuma kwezicubu kuyakhuthazwa, futhi ukwakheka kwengqimba yokuphuma kwezicubu kuyasheshiswa, okuholela ekuqhekekeni kwezitho zomzimba.
I-Ethephon ingathuthukisa umsebenzi wama-enzyme, futhi ingavuselela i-phosphatase namanye ama-enzyme ahlobene nokuvuthwa kwezithelo lapho izithelo sezivuthiwe ukuze ikhuthaze ukuvuthwa kwezithelo. I-Ethephon iwumlawuli wokukhula kwezitshalo osezingeni eliphezulu futhi osebenza kahle kakhulu. I-molecule ye-ethephon ingakhipha i-molecule ye-ethylene, enemiphumela yokukhuthaza ukuvuthwa kwezithelo, ukukhuthaza ukugeleza kwezilonda, kanye nokulawula ukuguqulwa kobulili.
Ukusetshenziswa okuyinhloko kwe-ethephon kufaka phakathi: ukukhuthaza ukuhlukaniswa kwezimbali zesifazane, ukukhuthaza ukuvuthwa kwezithelo, ukukhuthaza ukufiphala kwezitshalo, kanye nokuqeda ukungakwazi ukutshala.
Ungayisebenzisa kanjani i-ethephon ngomphumela omuhle?
1. Isetshenziselwa ukuvuthwa kwekotini:
Uma ukotini unamandla anele, ipentshisi lasekwindla livame ukuvuthwa nge-ethephon. Ukusetshenziswa kwe-ethephon kukotini kudinga ukuthi iningi lama-boll ekotini ensimini yokotini libe nobudala bezinsuku ezingaphezu kuka-45, futhi izinga lokushisa lansuku zonke kufanele libe ngaphezu kwama-degrees angu-20 uma kusetshenziswa i-ethephon.
Ukuze kuvuthwe ukotini, i-ethephon engu-40% isetshenziswa kakhulu ukuncibilikisa uketshezi izikhathi ezingu-300 ~ 500, bese ifafazwa ekuseni noma lapho izinga lokushisa liphezulu. Ngokuvamile, ngemva kokufaka i-ethephon kukotini, ingasheshisa ukuqhekeka kwama-boll okotini, inciphise ukuqhakaza ngemva kwesithwathwa, ithuthukise ngempumelelo ikhwalithi yokotini, ngaleyo ndlela ikhulise isivuno sokotini.
2. Isetshenziselwa ukuna kwe-jujube, i-hawthorn, i-olive, i-ginkgo nezinye izithelo:
I-Jujube: Kusukela esigabeni sokuvuthwa okumhlophe kuya esigabeni sokuvuthwa okuqinile kwe-jujube, noma ezinsukwini eziyi-7 kuya kweziyi-8 ngaphambi kokuvuna, kuyinto evamile ukufafaza i-ethephon. Uma isetshenziselwa ukucubungula izinsuku ezifakwe amaswidi, isikhathi sokufafaza singathuthukiswa ngokufanele, futhi ukuhlushwa kwe-ethephon efafaziwe kungu-0.0002%. ~0.0003% kuhle. Ngenxa yokuthi ikhasi le-jujube lincane kakhulu, uma liwuhlobo lokudla okuluhlaza, akufaneleki ukusebenzisa i-ethephon ukuze ulilahle.
I-Hawthorn: Ngokuvamile, isisombululo se-ethephon esingu-0.0005% ~ 0.0008% sifuthwa ezinsukwini ezingu-7 ~ 10 ngaphambi kokuvunwa okuvamile kwe-hawthorn.
Ama-olive: Ngokuvamile, isixazululo se-ethephon esingu-0.0003% siyafuthwa lapho ama-olive esesondele ekuvuthweni.
Izithelo ezingenhla zingawa ngemva kwezinsuku ezintathu kuya kwezine emva kokufutha, shukumisa amagatsha amakhulu.
3. Ukuvuthwa kukatamatisi:
Ngokuvamile, kunezindlela ezimbili zokuvuthwa kwamatamatisi nge-ethephon. Enye iwukucwilisa izithelo ngemva kokuvuna. Kumatamatisi akhule kodwa angakavuthwa “ngesikhathi sokushintsha umbala”, wafake esixazululweni se-ethephon esinokuqukethwe okungu-0.001% ~ 0.002%., futhi ngemva kwezinsuku ezimbalwa zokufakwa, amatamatisi azophenduka abe bomvu futhi avuthwe.
Okwesibili ukupenda isithelo esihlahleni sikatamatisi. Faka isisombululo se-ethephon esingu-0.002% ~ 0.004% esithelweni sikatamatisi "esikhathini sokushintsha umbala". Utamatisi ovuthwe ngale ndlela ufana nesithelo esivuthiwe ngokwemvelo.
4. Ukuze ikhukhamba likhange izimbali:
Ngokuvamile, uma izithombo zekhukhamba zinamaqabunga eqiniso angu-1 kuya kwangu-3, isixazululo se-ethephon esinokuqukethwe okungu-0.0001% kuya ku-0.0002% siyafuthwa. Ngokuvamile, sisetshenziswa kanye kuphela.
Ukusetshenziswa kwe-ethephon esigabeni sokuqala sokwehlukaniswa kwamahlumela ezimbali kumakhukhamba kungashintsha umkhuba wokuqhakaza, kubangele ukuvela kwezimbali zesifazane kanye nezimbali zesilisa ezimbalwa, ngaleyo ndlela kwandise inani lamakhabe kanye nenani lamakhabe.
5. Ukuvuthwa kukabhanana:
Ukuze ubhanana uvuthwe nge-ethephon, isisombululo se-ethephon esingu-0.0005% ~ 0.001% sivame ukusetshenziselwa ukufutha noma ukufutha ubhanana ovuthiwe oyisikhombisa noma ayisishiyagalombili. Ukushisa kuyadingeka kuma-degrees angu-20. Ubhanana ophathwe nge-ethephon ungathamba ngokushesha futhi uphenduke ophuzi, i-astringency iyanyamalala, isitashi siyancipha, futhi okuqukethwe ushukela kuyanda.
