Ekuphileni kwansuku zonke, i-ethephon ivame ukusetshenziselwa ukuvuthwa ubhanana, utamatisi, ama-persimmons nezinye izithelo, kodwa yimiphi imisebenzi ethile ye-ethephon?Ungayisebenzisa kanjani kahle?
I-Ethephon, efana ne-ethylene, ngokuyinhloko ithuthukisa ikhono le-ribonucleic acid synthesis kumaseli futhi ikhuthaza ukuhlanganiswa kwamaprotheni.Endaweni yezitshalo, njengama-petioles, iziqu zezithelo, kanye nesisekelo samacembe, ngenxa yokwanda kwe-protein synthesis, ukuvuselelwa kabusha kwe-cellulase kungqimba lwe-abscission kuyakhuthazwa, futhi ukwakheka kongqimba lwe-abscission kuyashesha. , okuholela ekuchithekeni kwezitho zomzimba.
I-Ethephon ingathuthukisa umsebenzi wama-enzyme, futhi ingaphinda isebenze i-phosphatase namanye ama-enzyme ahlobene nokuvuthwa kwezithelo lapho isithelo sesivuthiwe ukukhuthaza ukuvuthwa kwezithelo.I-Ethephon iyisilawuli sokukhula kwezitshalo esisezingeni eliphezulu futhi esisebenza kahle kakhulu.I-molecule ye-ethephon ingakhulula i-molecule ye-ethylene, enemiphumela yokugqugquzela ukuvuthwa kwezithelo, ukuvuselela ukugeleza kwamanxeba, nokulawula ukuguqulwa kobulili.
Ukusetshenziswa okuyinhloko kwe-ethephon kuhlanganisa: ukugqugquzela ukuhlukaniswa kwezimbali zabesifazane, ukugqugquzela ukuvuthwa kwezithelo, ukugqugquzela ukufiphaza kwezitshalo, nokuphula ukulala kwezitshalo.
Ungayisebenzisa kanjani i-ethephon ngomphumela omuhle?
1. Isetshenziselwa ukuvuthwa ukotini:
Uma ukotini unamandla okwanele, ipentshisi lasekwindla livame ukuvuthwa nge-ethephon.Ukusetshenziswa kwe-ethephon ukotini kudinga ukuthi iningi lamabholi kakotini ensimini kakotini abe nobudala obungaphezu kwezinsuku ezingama-45, futhi izinga lokushisa lansuku zonke kufanele libe ngaphezu kwama-degree angu-20 uma usebenzisa i-ethephon.
Ekuvuthweni kukakotini, i-ethephon engu-40% isetshenziswa kakhulu ukuhlambulula izikhathi ezingama-300 ~ 500 zoketshezi, bese uyifutha ekuseni noma lapho izinga lokushisa liphezulu.Ngokuvamile, ngemva kokusetshenziswa kwe-ethephon ukotini, ingasheshisa ukuqhekeka kwamabholi kakotini, inciphise ukuqhakaza ngemva kwesithwathwa, ithuthukise ngokuphumelelayo izinga likakotini, ngaleyo ndlela yandise isivuno sikakotini.
2. Isetshenziselwa ukuwa kwe-jujube, i-hawthorn, umnqumo, i-ginkgo nezinye izithelo:
I-Jujube: Kusukela esigabeni sokuvuthwa esimhlophe kuya esigabeni sokuvuthwa okupholile kwejujube, noma izinsuku eziyi-7 kuya kweziyi-8 ngaphambi kokuvuna, kuyisiko ukufafaza i-ethephon.Uma isetshenziselwa ukucubungula izinsuku ze-candied, isikhathi sokufafaza singathuthukiswa ngokufanele, futhi ukugxiliswa kwe-ethephon okufafaziwe ngu-0.0002%.~0.0003% yinhle.Ngenxa yokuthi ikhasi le-jujube lincane kakhulu, uma kuwuhlobo lokudla okuluhlaza, akufanelekile ukusebenzisa i-ethephon ukuyiyeka.
I-Hawthorn: Ngokuvamile, isisombululo se-ethephon sokugxilisa esingu-0.0005% ~ 0.0008% sifuthwa ezinsukwini ezingu-7~10 ngaphambi kokuvunwa okujwayelekile kwe-hawthorn.
Iminqumo: Ngokuvamile, isixazululo se-ethephon esingu-0.0003% siyafafazwa lapho iminqumo isiseduze nokuvuthwa.
Izithelo ezingenhla zingawa emva kwezinsuku ezi-3 kuya kwezi-4 emva kokufafaza, nyakazisa amagatsha amakhulu.
3. Ukuvuthwa kukatamatisi:
Ngokuvamile, kunezindlela ezimbili zokuvuthwa utamatisi nge-ethephon.Enye iwukucwilisa isithelo ngemva kokuvuna.Kutamatisi osekhulile kodwa ongakavuthwa “enkathini yokushintsha umbala”, wabeke esixazululweni se-ethephon ngokugxila kuka-0.001%~0.002%., futhi ngemva kwezinsuku ezimbalwa zokupakisha, utamatisi uzoba bomvu futhi uvuthwe.
Okwesibili ukudweba isithelo esihlahleni sikatamatisi.Faka isixazululo se-ethephon esingu-0.002%~0.004% esithelweni sikatamatisi "esikhathini sokushintsha umbala".Utamatisi ovuthwe ngale ndlela ufana nesithelo esivuthiwe ngokwemvelo.
4. Ukuze ikhukhamba ihehe izimbali:
Ngokuvamile, lapho izithombo zekhukhamba zinamaqabunga eqiniso angu-1 kuya kwangu-3, isisombululo se-ethephon esine-concentration ye-0.0001% kuya ku-0.0002% siyafafazwa.Ngokuvamile, isetshenziswa kanye kuphela.
Ukusetshenziswa kwe-ethephon esigabeni sokuqala sokuhlukaniswa kwezimbali zamakhukhamba kungashintsha umkhuba wokuqhakaza, kubangele ukuvela kwezimbali zabesifazane kanye nezimbali ezimbalwa zesilisa, ngaleyo ndlela kwandise inani lamakhabe kanye nenani lamakhabe.
5. Ukuvuthwa kukabhanana:
Ukuvuthwa kukabhanana nge-ethephon, isisombululo se-ethephon esingu-0.0005%~0.001% sivame ukusetshenziselwa ukumithisa noma ukufafaza kubhanana ovuthiwe oyisikhombisa noma ayisishiyagalombili.Ukushisa kuyadingeka kuma-degree angu-20.Ubhanana ophathwa nge-ethephon ungashesha ukuthambisa futhi uphenduke ophuzi, i-astringency iyanyamalala, isitashi siyancipha, futhi okuqukethwe ushukela kuyanda.
