Ihlobo lifikile, kwaye eyona nto ididayo kumntu wonke kukugcinwa kokutya.Ukuqinisekisa njani ukutsha kokutya kube ngumba oshushu kule mihla.Ngoko ke, sifanele sizigcine njani iziqhamo nemifuno emitsha kwihlobo elishushu ngolo hlobo?Xa ujongene nale meko, kwiminyaka yakutshanje, uphando lwezenzululwazi lufumene inhibitor esebenzayo yesenzo se-ethylene -1-MCP.I-1-MCP inhibitor ayiyona nje ityhefu, ayinabungozi, i-residue free, kwaye ihambelana nokusingqongileyo, kodwa isetyenziselwa ngokubanzi ukugcinwa kweziqhamo, imifuno kunye neentyatyambo.Ngezantsi, siya kwazisa iinkcukacha ezithile zemveliso ye-1-MCP.
Yintoni i-1-MCP?
1-MCP, ekwabizwa ngokuba yi-1-Methylcycloprotene,I-CAS 3100-04-7.I-1-MCP iyi-ethylene inhibitor esebenzayo enokuthintela uchungechunge lwe-physiological and biochemical reactions ezinxulumene nokuvuthwa kweziqhamo okubangelwa yi-ethylene, inqanda ukuphefumla kwezityalo, ukulibazisa ngokufanelekileyo ukuvuthwa kweziqhamo kunye nenkqubela phambili yokuguga, ukugcina inkangeleko yokuqala kunye nomgangatho weziqhamo kunye nemifuno. ixesha elide, ukunciphisa ukuphuphuma kwamanzi, ukunciphisa umonakalo we-pathological kunye nokubola kwe-microbial, Ukugcina umgangatho wokugcinwa kwesiqhamo.Kwaye i-1-MCP ayinayo ityhefu kunye nentsalela ekhululekile, idibana nezalathi ezahlukeneyo zokugcinwa kwevidiyo yesizwe, kwaye inokusetyenziswa ngokuzithemba.

1-MCP isicelo
Ngaphambi kokusetyenziswa kwe-1-MCP, iindlela ezininzi zokugcinwa kunye nokugcinwa komzimba zamkelwe: 1. ifriji yokushisa ephantsi, 2. ukugcinwa kwe-atmospheric elawulwayo, kunye ne-3. ukushisa, ukukhanya, kunye nonyango lwe-microwave.Nangona kunjalo, ezi ndlela zintathu zifuna abasebenzi abaninzi kunye nezibonelelo, kwaye ixesha lide kwaye lifutshane.Uphando lubonise ukuba i-1-MCP inokukhuphisana ngokufanelekileyo ukubopha kwi-ethylene receptors, ukulibazisa ukuvuthwa kweziqhamo kunye nokuguga.Ngenxa yeempawu zayo ezingenabuthi, ukusetyenziswa okuphantsi, ukusebenza kakuhle okuphezulu, kunye neepropati zekhemikhali ezizinzile, okwangoku zisetyenziswa ngokubanzi ekugcinweni kweziqhamo kunye nemifuno, kunye nokusetyenziswa kweemarike eziphezulu kunye nezinga lokunyusa.
I-1-MCP ayithinteli kuphela okanye ibambezeleke ukuguga komzimba kwizityalo, kodwa inetyhefu ephantsi.I-LD50>5000mg/kg eneneni yinto engeyotyhefu;Ugxininiso olusetyenzisiweyo luphantsi kakhulu, kwaye xa kusetyenzwa iziqhamo, imifuno kunye neentyatyambo, ukugxila emoyeni kufuneka kube sisigidi esinye, ngoko ke intsalela yeziqhamo, imifuno kunye neentyatyambo emva kokusetyenziswa iphantsi kakhulu kangangokuba ayinakubonwa. ;I-1-MCP iphinde idlulise ukuhlolwa kwe-Arhente yoKhuseleko lweNdalo yase-US (isibhengezo sewebhusayithi ye-EPA) kwaye ithathwa njengekhuselekile kwaye ingenabungozi, ifanelekile ukusetyenziswa kwiintyatyambo kunye neziqhamo kunye nemifuno, kwaye ikhuselekile kubantu, izilwanyana kunye nokusingqongileyo.Akukho mfuneko yokumisela izithintelo zedosi ngexesha lokusetyenziswa.
Ithini imbonakalo yemarike ye-1-MCP?
Kumazwe ezolimo, inani elikhulu leziqhamo kunye nemifuno ezitsha ziveliswa minyaka le.Ngenxa yophuhliso olungafezekanga lwezixhobo ezibandayo zeemveliso zezolimo, malunga ne-85% yeziqhamo kunye nemifuno zisebenzisa izixhobo eziqhelekileyo, okukhokelela ekuboleni kunye nelahleko enkulu.Oku kunika indawo yemarike ebanzi yokukhuthaza kunye nokusetyenziswa kwe-1-methylcyclopropene.Iziphumo zophando zibonisa ukuba i-1-methylcyclopropene inokunciphisa kakhulu ukuthambisa kunye nokubola kweziqhamo kunye nemifuno, kunye nokwandisa ubomi babo beshelufu kunye nexesha lokugcina.Oku kuqukumbela ukwaziswa kwe1-MCP.Ukuba ungathanda ukwazi ngakumbi malunga nemveliso, nceda undishiye umyalezo.
