Ukukhutshwa kwe-ethylene ukusukaethephonisisombululo asihambelani nje ngokusondeleyo nexabiso le-pH, kodwa sinxulumene neemeko zangaphandle zokusingqongileyo ezifana neqondo lokushisa, ukukhanya, ukufuma, njl., Ngoko qiniseka ukuba ubeke ingqalelo kule ngxaki esetyenziswayo.
(1) Ingxaki yobushushu
Ukubola kweethephonkwandisa ngokunyuka kwamaqondo obushushu.Ngokovavanyo, phantsi kweemeko ze-alkaline, i-ethephon inokuchithwa ngokupheleleyo kwaye ikhutshwe emanzini abilayo imizuzu engama-40, ishiya i-chlorides kunye ne-phosphates.Kungqinwe ngokwenza ukuba ifuthe le-ethephon kwizityalo linxulumene nobushushu ngelo xesha.Ngokuqhelekileyo, kuyimfuneko ukugcina ubushushu obufanelekileyo kwixesha elithile emva kokuba unyango lube nefuthe elicacileyo, kwaye ngaphakathi kwinqanaba elithile lokushisa, umphumo uyanda ngokunyuka kweqondo lokushisa.
Umzekelo,ethephoninefuthe elihle ekuvuthweni kweeboli zomqhaphu kubushushu obungama-25 °C;20 ~ 25 °C nayo inesiphumo esithile;ngaphantsi kwe-20 °C, isiphumo sokuvuthwa sibi kakhulu.Oku kungenxa yokuba i-ethylene idinga iimeko ezifanelekileyo zokushisa kwinkqubo yokuthatha inxaxheba kwizityalo ze-physiological and biochemical activities.Ngexesha elifanayo, ngaphakathi kwinqanaba elithile lobushushu, inani le-ethephon elingena kwisityalo liyakhula ngokunyuka kweqondo lokushisa.Ukongeza, ubushushu obuphezulu bunokukhawulezisa ukuhamba kwe-ethephon kwisityalo.Ngoko ke, iimeko ezifanelekileyo zokushisa zinokuphucula umphumo wesicelo se-ethephon.
(2) Iingxaki zokukhanyisa
Ubunzulu bokukhanya obuthile bunokukhuthaza ukufunxwa kunye nokusetyenziswa kweethephonngezityalo.Ngaphantsi kweemeko zokukhanya, i-photosynthesis kunye nokuguqulwa kwezityalo ziqiniswa, ezihambelana nokuqhutyelwa kwe-ethephon kunye nokuthuthwa kwezinto eziphilayo, kwaye i-stomata yamagqabi ivulekile ukuququzelela ukungena kwe-ethephon emagqabini.Ngoko ke, izityalo kufuneka zisebenzise i-ethephon kwiintsuku ezinelanga.Nangona kunjalo, ukuba ukukhanya kunamandla kakhulu, ulwelo lwe-ethephon olutshizwe emagqabini lulula ukomisa, oluya kuchaphazela ukufunxwa kwe-ethephon ngamagqabi.Ngoko ke, kuyimfuneko ukuphepha ukutshiza phantsi kokukhanya okutshisayo kunye nokunamandla emini ehlobo.
(3) Ukufuma komoya, umoya kunye nemvula
Ukufuma komoya kuya kuchaphazela ukufunxaethephonngezityalo.Ukufuma okuphezulu akulula ukuba ulwelo lome, olulungele ukuba i-ethephon ingene kwisityalo.Ukuba umswakama uphantsi kakhulu, i-liquid iya koma ngokukhawuleza kwindawo yeqabunga, eya kuchaphazela inani le-ethephon engena kwisityalo..Kungcono ukutshiza i-ethephon ngempepho.Umoya unamandla, ulwelo luya kusasazwa ngumoya, kwaye ukusebenza kakuhle kokusetyenziswa kuphantsi.Ngoko ke, kuyimfuneko ukukhetha usuku olunelanga kunye nomoya omncinci.
Kufuneka kungabikho mvula kwiiyure ezi-6 emva kokutshiza, ukuze kuthintelwe ukukhukuliseka kwe-ethephon yimvula kwaye kuchaphazele ukusebenza kakuhle.
