Kusukela ekuqaleni kwehlobo, amazinga okushisa ezindaweni ezahlukene abelokhu ekhuphuka njalo. Sonke siyazi ukuthi izithelo nemifino kulula kakhulu ukubola njengoba amazinga okushisa enyuka. Lokhu kungenxa yokuthi imifino nezithelo ziqukethe izakhamzimba eziningi nama-enzyme ngokwawo. Njengoba amazinga okushisa enyuka, ukuphefumula kwezithelo nemifino nge-aerobic kuyashesha. Ngaphezu kwalokho, amazinga okushisa aphezulu azokwandisa kakhulu ukwanda kwamagciwane nesikhunta, okubangela izithelo ukuba zisheshise ukubola. Ngakho-ke, indlela yokulondoloza izithelo nemifino ehlobo isibe enye yezinkinga wonke umuntu akhathazekile ngazo.
Njengoba kwaziwa kahle, kunezinhlobo eziningi zezithelo zesizini ehlobo, ezihlukile kwezithelo zasekwindla futhi zingalengiswa ezihlahleni isikhathi eside. Uma izithelo ehlobo zingavunwa ngesikhathi esifanele ngemva kokuvuthwa, zingabola kalula noma zidliwe yizinyoni. Ngakho-ke, lokhu kudinga abalimi ukuthi bavune futhi bafake efrijini izithelo nemifino ngokushesha ngemva kokuvuthwa. Njengoba sibhekene nomsebenzi omkhulu kangaka, singazilondoloza kanjani kangcono izithelo nemifino ehlobo?
Empilweni yansuku zonke, lapho sibhekene nesimo sezulu esishisayo, sivame ukusebenzisa isiqandisi sethu ekhaya ukuze silondoloze ubusha bezithelo nemifino. Yiqiniso, lokhu kuzonciphisa ngezinga elithile inani lokuthenga kwethu. Ezitolo ezinkulu ezinkulu, indawo yokugcina ebandayo ingasetshenziswa ukugcina, okwandisa nezindleko zokugcina. Njengoba sibhekene nale nkinga, sithuthukise i-1-mcp, okuwubuchwepheshe bokugcina izinto zokugcina ezingonakalisi ukungcola, obungenabo ubuthi, futhi obungenazo izinsalela, obubaluleke kakhulu ekwandiseni impilo yeshelufu yemifino, izithelo nezimbali.
Kuyini i-1-MCP?
1-MCPyi-1-Methylcyclopene, inombolo ye-cas.3100-04-7I-1-MCP, njenge-cyclopropene compound, iphephile futhi ayinabo ubuthi. Empeleni, iyi-ethylene antagonist compound ephumelelayo futhi iyingxenye yesigaba se-synthetic plant growth controls. Njenge-food preservative, isetshenziswe kabanzi kwezentengiselwano. Abasabalalisi abaningi basebenzisa i-1-MCP ukugcina endaweni elawulwayo ezindaweni zokugcina izithelo, okungahlala izinyanga eziningana.I-1-Methylcyclopropen (1-MCP)ixazulula ngempumelelo inkinga yobunzima bokugcina izithelo nemifino ehlobo.
Imininingwane ye-1-MCP:
| Into | Okujwayelekile | Umphumela |
| Ukubukeka | Cishe i-powder emhlophe | Abafanelekile |
| Ukuhlolwa (%) | ≥3.3 | 3.6 |
| Ubumsulwa (%) | ≥98 | 99.9 |
| Ukungcola | Akukho ukungcola okukhulu | Akukho ukungcola okukhulu |
| Umswakama (%) | ≤10.0 | 5.2 |
| Umlotha（%） | ≤2.0 | 0.2 |
| Amanzi ancibilikayo | Isampula eli-1g lincibilikiswe ngokuphelele ku-100g wamanzi | Kuqediwe ngokuphelele |
Ukusetshenziswa kwe-1-MCP:
1-Methylcyclopropeneingasetshenziswa ekulondolozweni kwezithelo, imifino, nezimbali ukuze zingaboli futhi zibune. Isibonelo, ingasetshenziswa ezithelweni nasemifino ehlukahlukene efana nama-apula, amapheya, ama-cherries, isipinashi, iklabishi, i-celery, upelepele oluhlaza, izaqathi, njll. Umsebenzi wayo oyinhloko ukunciphisa ukuhwamuka kwamanzi, ukubambezela ukuvuthwa kwezithelo nemifino, nokugcina ubulukhuni bazo, ukunambitheka, kanye nokwakheka kokudla okunempilo; Ngokuphathelene nezimbali, i-1-Methylcyclopropene ingaqinisekisa umbala nephunga lezimbali, njenge-tulips, izimbali eziyisithupha, ama-carnation, ama-orchid, njll. Ngaphezu kwalokho, i-1-MCP ingathuthukisa ukumelana nezifo kwezitshalo ezifana nezimbali. Ukusetshenziswa kabanzi kwe1-MCPfuthi kuyingqophamlando entsha ekulondolozweni kwezithelo, imifino, nezimbali.
I-1-Methylcyclopropene inganciphisa kakhulu ukuthamba nokubola kwezithelo nemifino, futhi yandise isikhathi sayo sokugcina kanye nesikhathi sokugcina. Ngenxa yokuthuthuka okungaphelele kwe-cold chain logistics yemikhiqizo yezolimo, cishe ama-85% ezithelo nemifino asebenzisa i-logistics evamile, okuholela ekuboleni nasekulahlekelweni okukhulu. Ngakho-ke, ukukhuthazwa nokusetshenziswa kwe-1-methylcyclopropene kunikeza isikhala semakethe esibanzi.
