Kubva pakutanga kwezhizha, tembiricha munzvimbo dzakasiyana siyana dzave dzichiwedzera. Tese tinoziva kuti michero nemiriwo zvinowanzo ora sezvo tembiricha ichiwedzera. Izvi zvinodaro nekuti miriwo nemichero zvine zvinovaka muviri zvakawanda nema enzymes pachazvo. Sezvo tembiricha ichiwedzera, kufema kwemichero nemiriwo kunokurumidza. Uyezve, tembiricha yakakwira inowedzera kuwanda kwemabhakitiriya nefungus, zvichiita kuti michero ikurumidze kuora. Saka, nzira yekuchengetedza michero nemiriwo muzhizha yave imwe yenyaya dzinonetsa munhu wese.
Sezvazvinozivikanwa, kune mhando dzakawanda dzemichero yemwaka muzhizha, dzakasiyana nemichero yemwaka wemwaka uye dzinogona kuturika pamiti kwenguva yakareba. Kana michero muzhizha ikasatorwa nenguva mushure mekuibva, inogona kuora kana kudyiwa neshiri. Saka, izvi zvinoda kuti varimi vatore michero nemiriwo nekukasika voiisa mufiriji mushure mekunge yakura. Takatarisana neprojekiti yakakura kudaro, tingachengetedza sei michero nemiriwo muzhizha?
Muhupenyu hwezuva nezuva, kana kuchipisa, tinowanzo shandisa firiji yedu kumba kuchengetedza michero nemiriwo. Ehe, izvi zvichaderedza huwandu hwezvatinotenga. Muzvitoro zvikuru, nzvimbo inotonhorera inogona kushandiswa kuchengetera, izvo zvinowedzerawo mutengo wekuchengetedza. Takatarisana nedambudziko iri, takagadzira 1-mcp, inova tekinoroji yekuchengetedza isina kusvibiswa, isina chepfu, uye isina marara, iyo ine kukosha kukuru mukuwedzera hupenyu hwemiriwo, michero, nemaruva.
Chii chinonzi 1-MCP?
1-MCPi1-Methylcyclopene, nhamba yekesi.3100-04-71-MCP, semushonga we cyclopropene, yakachengeteka uye haina chepfu. Chaizvoizvo, imushonga unoshanda we ethylene antagonist uye uri muboka revanogadzirisa kukura kwezvirimwa. Semushonga wekuchengetedza chikafu, wave uchishandiswa zvakanyanya mukutengeserana. Vatengesi vazhinji vanoshandisa 1-MCP kuichengeta munzvimbo inodzorwa mumatura emichero, ayo anogona kugara kwemwedzi yakati wandei.1-Methylcyclopropen (1-MCP)inogadzirisa zvinobudirira dambudziko rekuomerwa kwekuchengeta michero nemiriwo mitsva muzhizha.
Magadzirirwo e1-MCP:
| Chinhu | Zvakajairika | Mhedzisiro |
| Chitarisiko | Upfu hunenge huchena | Anokodzera |
| Kuyedza (%) | ≥3.3 | 3.6 |
| Kuchena (%) | ≥98 | 99.9 |
| Kusachena | Hapana tsvina huru | Hapana tsvina huru |
| Hunyoro (%) | ≤10.0 | 5.2 |
| Dota (%) | ≤2.0 | 0.2 |
| Mvura inonyunguduka | 1g yemuenzaniso yakanyungudutswa zvachose mu100g yemvura | Yakanyungudutswa zvizere |
Kushandiswa kwe1-MCP:
1-Methylcyclopropeneinogona kushandiswa mukuchengetedza michero, miriwo, nemaruva kudzivirira kuora nekuoma. Semuenzaniso, inogona kushandiswa pamichero nemiriwo yakasiyana-siyana yakaita semaapuro, mapeya, macherries, sipinachi, kabichi, celery, mhiripiri yegirini, makarotsi, nezvimwewo. Basa rayo guru nderekuderedza kupwa kwemvura, kunonoka kuibva kwemichero nemiriwo, uye kuchengetedza kuomarara kwayo, kuravira, uye kuumbwa kwezvinovaka muviri; Panyaya yemaruva, 1-Methylcyclopropene inogona kuve nechokwadi cheruvara nekunhuhwirira kwemaruva, akadai sematulip, maruva matanhatu, macarnations, maorchid, nezvimwewo. Pamusoro pezvo, 1-MCP inogona kuvandudza kurwiswa kwezvirwere kwezvirimwa zvakaita semaruva. Kushandiswa kwakapararira kwe1-MCPzvakare chiitiko chitsva mukuchengetedza michero, miriwo, nemaruva.
1-Methylcyclopropene inogona kuderedza zvakanyanya kupfava nekuora kwemichero nemiriwo, uye kuwedzera nguva yekuichengeta. Nekuda kwekusagadzikana kwekugadzirwa kwezvinhu zvinotonhora zvezvirimwa, inenge 85% yemichero nemiriwo inoshandisa zvinhu zvakajairika, zvichikonzera kuora nekurasikirwa kukuru. Nokudaro, kusimudzirwa nekushandiswa kwe1-methylcyclopropene kunopa nzvimbo yakakura yemusika.
