Kusukela ekuqaleni kwehlobo, amazinga okushisa ezifundeni ezihlukahlukene abelokhu enyuka ngokuqhubekayo. Sonke siyazi ukuthi izithelo nemifino kujwayele ukonakala njengoba izinga lokushisa likhuphuka. Lokhu kungenxa yokuthi imifino nezithelo kuqukethe imisoco eminingi nama-enzyme ngokwawo. Njengoba izinga lokushisa likhuphuka, ukuphefumula kwe-aerobic kwezithelo nemifino kuba ngokushesha. Ngaphezu kwalokho, amazinga okushisa aphezulu azokwandisa kakhulu ukwanda kwamagciwane kanye nesikhunta, okubangela ukuthi izithelo zisheshise ukubola. Ngakho-ke, indlela yokulondoloza izithelo nemifino ehlobo isibe enye yezinkinga wonke umuntu akhathazeke ngazo.
Njengoba kwaziwa, kunezinhlobo eziningi zezithelo zonyaka ehlobo, ezingafani nezithelo zasekwindla futhi zingalengiswa ezihlahleni isikhathi eside. Uma izithelo ehlobo zingakhiwanga ngesikhathi ngemuva kokuvuthwa, zingabola kalula noma zidliwe yizinyoni. Ngakho-ke, lokhu kudinga ukuthi abalimi bakha ngokushesha futhi bafake efrijini izithelo nemifino ngemva kokuvuthwa. Njengoba sibhekene nomsebenzi omkhulu kangaka, kufanele sizigcine kanjani kangcono izithelo nemifino ehlobo?
Ekuphileni kwansuku zonke, lapho sibhekene nesimo sezulu esishisayo, sivame ukusebenzisa isiqandisi sethu ekhaya ukuze silondoloze ubusha bezithelo nemifino. Yebo, lokhu kuzokhawulela inani lokuthenga kwethu ngokwezinga elithile. Ezitolo ezinkulu, indawo yokugcina ebandayo ingase isetshenziselwe ukugcinwa, okwandisa nezindleko zokugcina. Njengoba sibhekene nale nkinga, sithuthukise i-1-mcp, engangcoli, engenabuthi, kanye nobuchwepheshe besitoreji samahhala esilondolozayo, esinokubaluleka okujulile ekwandiseni impilo yeshalofu yemifino, izithelo, nezimbali.
Iyini i-1-MCP?
1-MCPi-1-Methylcyclopene, cas No.3100-04-7I-1-MCP, njengenhlanganisela ye-cyclopropene, iphephile futhi ayinabo ubuthi. Empeleni, iyinhlanganisela esebenzayo ye-ethylene ephikisanayo futhi ingeyesigaba sezilawuli zokukhula kwezitshalo zokwenziwa. Njengesilondolozi sokudla, sesisetshenziswe kabanzi kwezentengiso Abasabalalisi abaningi basebenzisa i-1-MCP ukuze bayigcine endaweni elawulwayo ezindaweni zokugcina izithelo, ezingahlala izinyanga ezimbalwa.I-1-Methylcyclopropen ( 1-MCP)ixazulula ngempumelelo inkinga yobunzima bokugcina izithelo nemifino esisha ehlobo.
1-MCP Imininingwane:
| Into | Okujwayelekile | Umphumela |
| Ukubukeka | Cishe Impushana Emhlophe | Ufanelekile |
| Isivivinyo (%) | ≥3.3 | 3.6 |
| Ukuhlanzeka (%) | ≥98 | 99.9 |
| Ukungcola | Akukho ukungcola kwe-macroscopic | Akukho ukungcola kwe-macroscopic |
| Umswakama (%) | ≤10.0 | 5.2 |
| Umlotha (%) | ≤2.0 | 0.2 |
| Amanzi ancibilikayo | I-1 g yesampula yachithwa ngokuphelele ku-100g wamanzi | Kuhlakazwe ngokugcwele |
Ukusetshenziswa kwe-1-MCP:
1-Methylcyclopropeneingasetshenziswa ekulondolozeni izithelo, imifino, nezimbali ukuze zingaboli futhi zibune. Isibonelo, ingasetshenziswa ezithelweni nemifino ehlukahlukene njengama-apula, amapheya, ama-cherries, isipinashi, iklabishi, isilimo esidliwayo esinamagatsha anamanzi, upelepele oluhlaza, izaqathe, njll. Umsebenzi wawo oyinhloko ukunciphisa ukuhwamuka kwamanzi, ukubambezela ukuvuthwa kwezithelo nemifino, futhi zilondoloze ubulukhuni bazo, ukunambitheka, kanye nokwakheka kwazo okunomsoco; Mayelana nezimbali, i-1-Methylcyclopropene ingaqinisekisa umbala nephunga lezimbali, ezifana nama-tulips, izimbali eziyisithupha, ama-carnations, ama-orchid, njll. Ngaphezu kwalokho, i-1-MCP ingathuthukisa ukumelana nezifo zezitshalo ezifana nezimbali. Ukusetshenziswa okwandile kwe1-MCPfuthi kuyingqopha-mlando entsha ekulondolozweni kwezithelo, imifino, nezimbali.
I-1-Methylcyclopropene inganciphisa kakhulu ukuthambisa nokubola kwezithelo nemifino, futhi yandise impilo yeshalofu nesikhathi sokugcina. Ngenxa yokuthuthukiswa okungaphelele kwe-cold chain logistics yemikhiqizo yezolimo, cishe u-85% wezithelo nemifino zisebenzisa izinto ezijwayelekile, okuholela ekuboleni nasekulahlekeni okukhulu. Ngakho-ke, ukukhuthazwa nokusetshenziswa kwe-1-methylcyclopropene kunikeza indawo yemakethe ebanzi.
