Kubomi bemihla ngemihla, i-ethephon idla ngokusetyenziswa ukuvuthwa kweebhanana, iitumato, iipersimmons kunye nezinye iziqhamo, kodwa yintoni imisebenzi ethile ye-ethephon? Ungayisebenzisa njani kakuhle?
I-Ethephon, efana ne-ethylene, ngokuyintloko iphucula amandla okwenziwa kwe-ribonucleic acid kwiiseli kwaye ikhuthaza ukwenziwa kweproteni. Kwindawo yokuphuma kwezityalo, njengee-petioles, iziqu zeziqhamo, kunye nesiseko samagqabi, ngenxa yokwanda kokwenziwa kweproteni, ukwenziwa kwakhona kwe-cellulase kumaleko wokuphuma kwezicubu kuyakhuthazwa, kwaye ukwakheka komaleko wokuphuma kwezicubu kuyakhawuleziswa, okubangela ukuba amalungu omzimba aphulukane.
I-Ethephon inokuphucula umsebenzi wee-enzymes, kwaye ingenza i-phosphatase kunye nezinye ii-enzymes ezinxulumene nokuvuthwa kweziqhamo xa isiqhamo sivuthiwe ukukhuthaza ukuvuthwa kweziqhamo. I-Ethephon ngumlawuli wokukhula kwezityalo okumgangatho ophezulu nosebenza kakuhle. Imolekyuli ye-ethephon inokukhupha imolekyuli ye-ethylene, enefuthe lokukhuthaza ukuvuthwa kweziqhamo, ukukhuthaza ukuhamba kwamanxeba, kunye nokulawula utshintsho lwesini.
Eyona ndlela isetyenziswa ngayo i-ethephon ibandakanya: ukukhuthaza ukwahluka kweentyatyambo eziziinkonde, ukukhuthaza ukuvuthwa kweziqhamo, ukukhuthaza ukukhula kwezityalo, kunye nokuphelisa ukungakwazi kwezityalo ukuhlala ixesha elide.
Uyisebenzisa njani i-ethephon ngesiphumo esihle?
1. Isetyenziselwa ukuvuthwa komqhaphu:
Ukuba umqhaphu unamandla aneleyo, ipesika yasekwindla idla ngokuvuthwa nge-ethephon. Ukusetyenziswa kwe-ethephon kumqhaphu kufuna ukuba uninzi lweebholi zekotoni kwintsimi yomqhaphu zibe nobude beentsuku ezingaphezu kwama-45, kwaye ubushushu bemihla ngemihla kufuneka bube ngaphezulu kwama-20 degrees xa usebenzisa i-ethephon.
Kwixesha lokuvuthwa komqhaphu, i-40% ye-ethephon isetyenziselwa kakhulu ukunyibilikisa ulwelo oluphindwe kayi-300 ~ 500, kwaye lutshizwe kusasa okanye xa ubushushu buphezulu. Ngokuqhelekileyo, emva kokufaka i-ethephon kumqhaphu, inokukhawulezisa ukuqhekeka kweebholi zekotoni, inciphise ukuqhakaza emva kweqabaka, iphucule umgangatho womqhaphu ngempumelelo, ngaloo ndlela inyuse isivuno somqhaphu.
2. Isetyenziselwa ukuwa kwejujube, hawthorn, olive, ginkgo kunye nezinye iziqhamo:
I-Jujube: Ukususela kwinqanaba lokuvuthwa okumhlophe ukuya kwinqanaba lokuvuthwa okuqinileyo kwe-jujube, okanye kwiintsuku ezisi-7 ukuya kwezisi-8 ngaphambi kokuvuna, kuqhelekile ukutshiza i-ethephon. Ukuba isetyenziselwa ukucubungula imihla etyiweyo, ixesha lokutshiza linokuphuculwa ngokufanelekileyo, kwaye uxinaniso lwe-ethephon etshiziweyo yi-0.0002%. ~0.0003% lilungile. Ngenxa yokuba ixolo le-jujube lincinci kakhulu, ukuba luhlobo lokutya olungavuthwanga, akufanelekanga ukusebenzisa i-ethephon ukuyilahla.
IHawthorn: Ngokubanzi, isisombululo se-ethephon esinomlinganiselo we-0.0005% ~ 0.0008% sitshizwa kwiintsuku ezisi-7 ~ 10 ngaphambi kokuvunwa okuqhelekileyo kwehawthorn.
Ii-Olive: Ngokubanzi, isisombululo se-ethephon esingu-0.0003% sitshizwa xa ii-olive zisondele ekuvuthweni.
Iziqhamo ezingasentla zingawa emva kweentsuku ezi-3 ukuya kwezi-4 emva kokutshiza, shukumisa amasebe amakhulu.
3. Ukuvuthwa kweetamatato:
Ngokubanzi, kukho iindlela ezimbini zokuvuthwa kweetamatisi nge-ethephon. Enye kukuzifunxa iziqhamo emva kokuvuna. Kwiitamatisi ezikhule kodwa zingakavuthwa ngexesha "lokutshintsha umbala", zifake kwisisombululo se-ethephon esinoxinzelelo lwe-0.001% ~ 0.002%., kwaye emva kweentsuku ezimbalwa zokuzibeka ndawonye, iitamatisi ziya kuba bomvu kwaye zivuthwe.
Okwesibini kukupenda isiqhamo kumthi wetamatato. Faka isisombululo se-ethephon esingu-0.002% ~ 0.004% kwisiqhamo setamatato "kwixesha lokutshintsha kombala". Itamatato evuthwe ngale ndlela ifana nesiqhamo esivuthiweyo ngokwendalo.
4. Ukuze ikhukhamba itsale iintyatyambo:
Ngokwesiqhelo, xa izithole zekhukhamba zinamagqabi okwenyani ali-1 ukuya kwama-3, isisombululo se-ethephon esinoxinzelelo lwe-0.0001% ukuya kwi-0.0002% siyatshizwa. Ngokwesiqhelo, sisetyenziswa kube kanye kuphela.
Ukusetyenziswa kwe-ethephon kwinqanaba lokuqala lokwahlulwa kwamahlumela eentyatyambo kwiikhukhamba kunokutshintsha indlela ezidubula ngayo iintyatyambo, kubangele ukuvela kweentyatyambo eziziimazi kunye neentyatyambo ezimbalwa zesilisa, ngaloo ndlela kwandisa inani leemelon kunye nenani leemelon.
5. Ukuvuthwa kwebhanana:
Ukuze iibhanana zivuthwe nge-ethephon, isisombululo se-ethephon esinomlinganiselo we-0.0005% ~ 0.001% sidla ngokusetyenziselwa ukufunxa okanye ukutshiza iibhanana ezivuthiweyo ezisixhenxe okanye ezisibhozo. Kufuneka ukufudumeza kwiidigri ezingama-20. Iibhanana eziphathwe nge-ethephon zinokuthamba ngokukhawuleza kwaye zijike zibe tyheli, i-astringency iyanyamalala, istatshi siyancipha, kwaye umxholo weswekile uyanda.
