Umhlinzeki Wefektri Ochwepheshe 1-MCP 1-Methylcyclopropene CAS 3100-04-7
I-1-Methylcyclopropene, efushaniswe ngokuthi i-1-MCP, ine-CAS 3100-04-7. I-1-Methylcyclopropene iwumlawuli obalulekile wokukhula kwezitshalo. I-1-MCP ingabopha kuma-receptor e-ethylene futhi inamandla okubopha aqinile kune-ethylene. Impuphu ye-1-mcp ingasebenza ngokungenakuguqulwa kuma-receptor e-ethylene futhi ivimbele ukubopha kwe-ethylene kuma-receptor ayo. Lokhu kungavimba uchungechunge lwezimpendulo zomzimba nezamakhemikhali ezihlobene nokuvuthwa kwezithelo okubangelwa yi-ethylene, kubambezele inqubo yokuvuthwa, futhi kufeze umphumela wokulondolozwa.
Ihlala isikhathi eside eshalofini. Uma nje i-1-MCP ikhona endaweni ezungezile, izithelo azikwazi ukuvuthwa kamuva. Inomsebenzi ophezulu kakhulu futhi ingasebenza ngokuhlushwa okungu-1ppm kuphela (izingxenye ngesigidi) emoyeni. I-1-methylcyclopropene, engenabo ubuthi futhi engenakho ukungcola, iyigesi eguquguqukayo engenabo ubuthi engashiyi zinsalela ngemva kokusetshenziswa. I-1-mcp ayithinti ikhwalithi yezithelo, ingalibazisa ukwehla kobulukhuni bezithelo kanye nokuqukethwe kwe-titrable acid, igcine ukunambitheka okungcono, futhi inciphise ukulahleka kwezakhamzimba. I-1-MCP ingavimbela nezifo ezivamile ezenzeka ngesikhathi sokulondolozwa kwesithelo, njengesifo sesikhumba se-tiger kuma-apula kanye nesifo samabala amnyama kumapheya. I-1-Methylcyclopropene iwumlawuli wokukhula kwezitshalo zokwenziwa, osetshenziswe kabanzi kwezentengiselwano.

1. Ukulondolozwa kwezithelo: Ukulibazisa ukuvuthwa, ukunciphisa izifo kanye nokulahlekelwa izakhamzimba
Ngezithelo ezikhiqiza i-ethylene ngokwazo (noma ezizwela kakhulu ku-ethylene), i-1-MCP ingagcina ikhwalithi yezithelo ngempumelelo futhi ingenye yezicelo eziyinhloko zokugcina nokuthutha kwezentengiselwano. I-1-Methylcyclopropene ingavimbela ukuvuthwa kwazo ngokushesha (njengokuphuzi kwesikhumba sikabhanana ngaphambi kwesikhathi kanye nokuthamba kwenyama kamango), ukuxazulula inkinga yokuthutha "yokonakala kalula ngemva kokuvuna" kwezithelo ezinjalo. Nweba irediyasi yokuthengisa.
2. Ukulondolozwa kwemifino: Gcina iqinile futhi ihlanzekile, futhi unciphise ukubuna nokubola
I-1-Methylcyclopropene isetshenziswa kakhulu emifinweni edinga ukugcina ukuthungwa okuqinile nokuqinile noma evame ukulahlekelwa amanzi nokubuna. Ifaneleka kakhulu ezinhlotsheni ezisaphefumula ngemva kokuvuna futhi ezithinteka kalula yi-ethylene, igcina isikhumba sesithelo siqinile. I-1-methylcyclopropene igwema ukugoba kwenyama noma ukungabi namandla kokunambitheka, futhi ngesikhathi esifanayo inciphisa ukubola okubangelwa yizinambuzane ezincane.
3. Ukulondolozwa kwezimbali: Yandisa isikhathi sokubuka futhi unciphise ukuwa kwezimbali nama-petal
Ezimbalini ezisikiwe noma ezifakwe ebhodweni ezizwela i-ethylene, i-1-MCP inganciphisa ukujiya kwezimbali kanye nokuphuma kwamacembe, ithuthukise inani lazo lokuhlobisa. Izinhlobo ezisebenzayo zifaka phakathi ukunciphisa ukulahleka ngesikhathi sokuthuthwa noma ukubekwa. Impuphu ye-1-mcp ifaneleka kakhulu ekuthuthweni kwezimbali ezintsha ezisikiwe kude kanye nokuthengiswa ezitolo zezimbali.
4. Okunye ukusetshenziswa okusizayo
Ngaphezu kokulondolozwa okuqondile, i-1-MCP ingadlala indima engaqondile ekukhiqizweni kwezitshalo. Ngesikhathi sesigaba sokutshala kwezithombo zezitshalo ezithile (njengezitshalo zokuhlobisa), ukuhlushwa okuphansi kwe-1-MCP kungasetshenziswa ukulawula isigqi sokukhula kwezitshalo, ukugwema ukubola noma ukuguga ngaphambi kwesikhathi. Impuphu ye-1-mcp ingasiza ekwandiseni isikhathi sokugcina ngemva kokuvuna futhi inciphise ukuwohloka kwezithako ezisebenzayo zezinye izinto zokwelapha zaseShayina ezilula.
1. Ubumsulwa: Izinga lomkhakha le-1-MCP lingu-3.3%, kodwa singafinyelela ku-3.7%.
2. Singanikeza ama-micro-doses, amaphakheji amancane angu-0.035%, ukuze asetshenziswe emashalofini ezitolo ezinkulu noma emabhokisini ezithelo.
3. Ukuphepha Komkhiqizo: I-1-MCP iyi-molecule yegesi ezonyamalala ngokuphelele ngemva kokucutshungulwa, ingashiyi nsalela yamakhemikhali kumkhiqizo.
Singabahlinzeki abangochwepheshe be-1-methylcyclopropene. Uma unentshisekelo ekuthengeni i-CAS 3100-04-71-mcp, sicela usithinte. Silangazelela ukubambisana nawe
