Ukukhululwa kwe-ethylene kwii-ethephonIsisombululo asihambelani nje kuphela nexabiso le-pH, kodwa sinxulumene neemeko zangaphandle zokusingqongileyo ezifana nobushushu, ukukhanya, ukufuma, njl.njl., ngoko ke qiniseka ukuba uyinika ingqalelo le ngxaki isetyenziswayo.
(1) Ingxaki yobushushu
Ukuqhekeka kwei-ethephoniyanda xa ubushushu bunyuka. Ngokwesi vavanyo, phantsi kweemeko ze-alkaline, i-ethephon inokubola ngokupheleleyo kwaye ikhutshwe emanzini abilayo imizuzu engama-40, ishiye ii-chloride kunye nee-phosphates. Kuye kwabonakaliswa ngokwesiqhelo ukuba isiphumo se-ethephon kwizityalo sinxulumene nobushushu ngelo xesha. Ngokubanzi, kuyimfuneko ukugcina ubushushu obufanelekileyo ixesha elithile emva konyango ukuze kube nesiphumo esicacileyo, kwaye ngaphakathi kobubanzi obuthile bobushushu, isiphumo siyanda xa ubushushu bunyuka.
Umzekelo,i-ethephoninefuthe elihle ekuvuthweni kweebholi zekotoni kubushushu obuyi-25 °C; 20 ~ 25 °C nayo inefuthe elithile; ngaphantsi kwe-20 °C, isiphumo sokuvuthwa asisihle kakhulu. Oku kungenxa yokuba i-ethylene ifuna iimeko ezifanelekileyo zobushushu kwinkqubo yokuthatha inxaxheba kwimisebenzi ye-physiological kunye ne-biochemical yezityalo. Kwangaxeshanye, ngaphakathi koluhlu oluthile lobushushu, ubungakanani be-ethephon engena kwisityalo buyanda ngokunyuka kobushushu. Ukongeza, ubushushu obuphezulu bunokukhawulezisa intshukumo ye-ethephon kwisityalo. Ke ngoko, iimeko ezifanelekileyo zobushushu zinokuphucula isiphumo sokusebenzisa i-ethephon.
(2) Iingxaki zokukhanyisa
Ukukhanya okunamandla athile kunokukhuthaza ukufunxwa nokusetyenziswai-ethephonyizityalo. Phantsi kweemeko zokukhanya, i-photosynthesis kunye nokuphefumla kwezityalo kuyaqiniswa, nto leyo enceda ekuhanjisweni kwe-ethephon kunye nokuthuthwa kwezinto eziphilayo, kwaye i-stomata yamagqabi ivulekile ukuze kube lula ukungena kwe-ethephon kumagqabi. Ke ngoko, izityalo kufuneka zisebenzise i-ethephon kwiintsuku ezinelanga. Nangona kunjalo, ukuba ukukhanya kunamandla kakhulu, ulwelo lwe-ethephon olutshizwa kumagqabi kulula ukuluma, nto leyo eya kuchaphazela ukufunxwa kwe-ethephon ngamagqabi. Ke ngoko, kuyimfuneko ukuphepha ukutshiza phantsi kokukhanya okushushu nokunamandla emini ehlotyeni.
(3) Ukufuma komoya, umoya kunye nemvula
Ukufuma komoya kuya kuchaphazela ukufunxwai-ethephonngezityalo. Umswakama ophezulu akulula ukuba ulwelo lome, nto leyo elula ukuba i-ethephon ingene kwisityalo. Ukuba umswakama uphantsi kakhulu, ulwelo luya koma ngokukhawuleza kumphezulu wegqabi, nto leyo eya kuchaphazela ubungakanani be-ethephon engena kwisityalo. . Kungcono ukutshiza i-ethephon ngomoya. Umoya unamandla, ulwelo luya kusasazeka nomoya, kwaye ukusebenza kakuhle kokusetyenziswa kuphantsi. Ke ngoko, kuyimfuneko ukukhetha usuku olunelanga olunomoya omncinci.
Akufuneki kubekho mvula zingadlulanga iiyure ezi-6 emva kokutshiza, ukuze kuthintelwe ukuba i-ethephon ingakhukuliswa yimvula ize ichaphazele ukusebenza kwayo.
