Kubomi bemihla ngemihla, i-ethephon isoloko isetyenziselwa ukuvuthwa kweebhanana, utamatisi, i-persimmons kunye nezinye iziqhamo, kodwa yintoni imisebenzi ethile ye-ethephon?Indlela yokuyisebenzisa kakuhle?
I-Ethephon, efana ne-ethylene, ngokuyinhloko iphakamisa amandla e-ribonucleic acid synthesis kwiiseli kwaye ikhuthaza ukuhlanganiswa kweeprotheni.Kwindawo yokukrala yezityalo, ezinje ngeepetioles, izikhondo zeziqhamo, kunye nesiseko samagqabi, ngenxa yokwanda kweprotein synthesis, ukuvuselelwa kwe-cellulase kumaleko we-abscission kuyakhuthazwa, kwaye ukwakheka komaleko we-abscission kuyakhawuleza. , okubangela ukuchithwa kwamalungu.
I-Ethephon inokunyusa umsebenzi we-enzymes, kwaye ingenza i-phosphatase kunye nezinye i-enzymes ezinxulumene nokuvuthwa kweziqhamo xa isiqhamo sivuthiwe ukukhuthaza ukuvuthwa kweziqhamo.I-Ethephon ngumgangatho ophezulu kunye nokulawula ukukhula kwezityalo.I-molecule ye-ethephon inokukhulula i-molecule ye-ethylene, enemiphumo yokukhuthaza ukuvuthwa kweziqhamo, ukuvuselela ukuhamba kwamanxeba, kunye nokulawula ukuguqulwa kwesini.
Olona setyenziso luphambili lwe-ethephon lubandakanya: ukukhuthaza ukwahlulwa kweentyantyambo zasemazi, ukukhuthaza ukuvuthwa kweziqhamo, ukukhuthaza ukuncipha kwezityalo, kunye nokophula ukungabikho kokulala kwezityalo.
Uyisebenzisa njani i-ethephon ngesiphumo esihle?
1. Isetyenziselwa ukuvuthwa komqhaphu:
Ukuba umqhaphu unamandla okwaneleyo, ipesika yasekwindla idla ngokuvuthwa nge-ethephon.Ukusetyenziswa kwe-ethephon kwikotoni kufuna ukuba uninzi lweebholi zekotoni kwibala lekotoni zineminyaka yobudala engaphezulu kweentsuku ezingama-45, kwaye ubushushu bemihla ngemihla kufuneka bube ngaphezu kwama-20 degrees xa usebenzisa i-ethephon.
Ukuvuthwa komqhaphu, i-ethephon ye-40% isetyenziselwa ukuhlambulula amaxesha angama-300 ~ 500 olwelo, kwaye uyitshize ekuseni okanye xa ubushushu buphezulu.Ngokuqhelekileyo, emva kokusetyenziswa kwe-ethephon kwikotoni, inokukhawulezisa ukuqhekeka kweebholi zekotoni, ukunciphisa ukuqhakaza emva kweqabaka, iphucule ngokufanelekileyo umgangatho wekotoni, kwaye ngaloo ndlela yandise isivuno somqhaphu.
2. Isetyenziselwa ukuwa kwe-jujube, i-hawthorn, i-olive, i-ginkgo kunye nezinye iziqhamo:
Jujube: Ukusukela kwinqanaba elimhlophe lokuvuthwa ukuya kwinqanaba lokuvuthwa kwejujube, okanye kwiintsuku ezisi-7 ukuya kwezisi-8 phambi kokuvunwa, kulisiko ukutshiza i-ethephon.Ukuba isetyenziselwa ukusetyenzwa kwemihla ye-candied, ixesha lokutshiza linokuqhubela phambili ngokufanelekileyo, kwaye i-concentration ye-ethephon etshisiweyo yi-0.0002%.~0.0003% ilungile.Kuba ixolo lejujube libhityile kakhulu, ukuba luhlobo lokutya okukrwada, akufanelekanga ukusebenzisa i-ethephon ukuyiwisa.
I-Hawthorn: Ngokuqhelekileyo, i-0.0005% ~ 0.0008% isisombululo se-ethephon sitshizwa kwiintsuku ezi-7 ~ 10 ngaphambi kokuvunwa okuqhelekileyo kwe-hawthorn.
Iminquma: Ngokuqhelekileyo, isisombululo se-ethephon se-0.0003% sitshizwa xa iminquma isondele ekuvuthweni.
Iziqhamo ezingentla zingawa emva kweentsuku ezi-3 ukuya kwezi-4 emva kokutshiza, shukumisa amasebe amakhulu.
3. Ukuvuthwa kwetumato:
Ngokuqhelekileyo, kukho iindlela ezimbini zokuvuthwa kweetumato nge-ethephon.Enye kukufunxa isiqhamo emva kokuvuna.Kwiitumato eziye zakhula kodwa zingekavuthwa "kwixesha lokutshintsha umbala", zibeke kwisisombululo se-ethephon kunye noxinzelelo lwe-0.001% ~ 0.002%., kwaye emva kweentsuku ezimbalwa zokupakisha, utamatisi uya kuba bomvu kwaye ukhule.
Okwesibini kukupenda isiqhamo kumthi wetamatato.Faka i-0.002% ~ 0.004% isisombululo se-ethephon kwisiqhamo setamatato "kwixesha lokutshintsha umbala".Itumato evuthwe ngale ndlela iyafana nesiqhamo esikhule ngokwendalo.
4. Ukuze ukhukhamba utsale iintyatyambo:
Ngokuqhelekileyo, xa izithole zekhukhamba zine-1 ukuya kwi-3 amaqabunga okwenyaniso, isisombululo se-ethephon kunye ne-concentration ye-0.0001% ukuya kwi-0.0002% ifafazwe.Ngokuqhelekileyo, isetyenziswa kanye kuphela.
Ukusetyenziswa kwe-ethephon kwinqanaba lokuqala lokwahlulahlula kweentyatyambo kwikhukhamba kunokutshintsha umkhwa weentyatyambo, kubangele ukuba kwenzeke iintyatyambo zabasetyhini kunye neentyantyambo ezimbalwa zamadoda, ngaloo ndlela ukwandisa inani leemelon kunye nenani leemelon.
5. Ukuvuthwa kwebhanana:
Ukuvuthwa kweebhanana nge-ethephon, i-0.0005% ~ 0.001% isisombululo se-ethephon ye-concentration idla ngokusetyenziselwa ukumitha okanye ukutshiza kwiibhanana ezisixhenxe okanye ezisibhozo ezivuthiweyo.Ukufudumala kuyadingeka kwii-degrees ezingama-20.Iibhanana eziphathwa nge-ethephon zinokukhawuleza zithobe kwaye zijike ziphuzi, i-astringency iyanyamalala, isitashi siyancipha, kwaye umthamo weswekile uyanda.
