1-Methylcyclopropene(yakapfupikiswa se1-MCP) CAS 3100-04-7, imorekuru diki ine chimiro chinotenderera uye inoshandiswa zvakanyanya mumunda wekuchengetedza zvigadzirwa zvekurima nekuda kwebasa rayo rakasiyana mukudzora mashandiro emiti.

1-Methylcyclopropene (1-MCP) chinhu chine mashandiro akasiyana uye chinoshanda zvakanyanya muminda yakawanda, kunyanya mukurima nekuchengetedza chikafu. Izvi zvinotevera mashandisirwo aro makuru uye zvimwe zvine chekuita nazvo:

Munda wekurima nekuchengetedza michero

1. Dzivisa kushanda kwe ethylene uye wedzera nguva yekutsva kwemichero

Nheyo yekushanda: Ethylene ihormone inokosha pakuibva nekuchembera kwemichero yezvirimwa. 1-MCP inogona kusunga zvachose kuma ethylene receptors, kuvharira kutapurirana kwechiratidzo che ethylene, uye nokudaro inonotsa kuibva, kupfava uye kuchembera kwemichero.

Mamiriro ekushandisa:

Kuchengetedza michero yakasiyana-siyana: yakaita semaapuro, mapeya, mabhanana, kiwi, mango, mastrawberry, nezvimwewo. Semuenzaniso, kana maapuro akarapwa ne1-MCP mushure mekutanhwa, anogona kuwedzera nguva yawo yekuchengetera mufiriji kana tembiricha yemumba, uye kuchengetedza kusimba uye magadzirirwo enyama.

Dzora zvirwere zvemuviri mushure mekukohwa: Deredza matambudziko akadai sebrowning uye kuora kwemichero kunokonzerwa ne ethylene (senge chirwere chemavanga matema mumabhanana).

Zvakanakira: Zvichienzaniswa nezvinhu zvinonwisa ethylene zvechinyakare (zvakaita se potassium permanganate),1-MCPine simba rinogara kwenguva refu uye rinoshanda, uye inoda dose shoma (kazhinji ppm shoma).

2. Kudzora kukwegura kwemaruva nemiti yekushongedza

Kushandiswa kuchengetedza maruva akachekwa: Wedzera hupenyu hwevhasi remaruva akachekwa akadai semaruva emumaruva, macarnation nemaruva, uye kunonotsa kusvava nekuoma kwemaruva.

Kutarisira zvirimwa zviri muhari: Kudzivirira kukwegura kwezvirimwa zvekushongedza zviri mumba (zvakaita sePhalaenopsis) uye kuchengetedza chimiro chinoyevedza chezvirimwa.

Munda wekurima zvirimwa nekurima

1. Kudzora kukura nekukura kwezvirimwa

Kunonoka kukwegura kwemiriwo: Inoshandiswa pakurapa miriwo yakaita sebroccoli nelettuce mushure mekukohwa kuti irambe iine ruvara rwayo rwegirini uye itsva.

Kudzora kuenderana kwekukura kwezvirimwa: Mukurima michero yakaita sematomatisi nemhiripiri, kurapwa kwe1-MCP kunoitwa kuti kukura kwemichero kuve kwakafanana, zvichiita kuti kukohwewa nekugadzirisa zvive nyore.

2. Deredza kushushikana kwezvirimwa

Kudzivirira kushushikana kwakanyanya: Kana zvinhu zvaoma kana kuti zvaoma (sekupisa kwakanyanya kana kwakaderera), zvinoderedza kushushikana kunokonzerwa ne ethylene mumiti, uye zvinoderedza kutsvuka kwemashizha.

Mamwe maapplication anogona kuitika

1. Kurapa kwepamberi pebasa rezvekudya

1-Methylcyclopropene inoshandiswa kuchengetedza michero mitsva (yakadai semaapuro nezvidimbu zvemapeya), kunonotsa oxidation uye Browning, uye kuwedzera nguva yekushanda kwayo.

2. Tsvagiridzo yesainzi uye tsvagiridzo yekuedza

Sechishandiso chekudzidza mashandiro anoita ethylene, inoshandiswa mukuyedza physiology yemiti uye molecular biology kuongorora mashandiro ekutonga kwenzira yekutumira ethylene.

Nzira dzekudzivirira pakushandisa

Nguva yakatarwa:1-Methylcyclopropeneinofanira kushandiswa isati yaburitswa ethylene kubva pamuchero kana chirimwa (senge nekukurumidza sezvinobvira mushure mekutanhwa) kuti ive nemigumisiro yakanaka. Kana muchero wasvika padanho rekupedzisira rekuibva, mhedzisiro yekurapa ichaderera.

Kudzora mwero wemushonga: Zvirimwa zvakasiyana zvine mwero wemushonga wakasiyana ku1-Methylcyclopropene 1-MCP (semuenzaniso, mhando yemushonga wemushonga inonyanyo shandiswa). Kuwanda kwemushonga kunofanira kugadziriswa zvichienderana nerudzi rwemuti kudzivirira kunaka kwemuchero kunokonzerwa nekuwanda kwemushonga (sekunge "kuumbwa kwemushonga" wemaapuro).

Mamiriro ekunze: Kurapa kunofanirwa kuitwa munzvimbo yakavharwa (senge imba yekuchengetera zvinhu ine mhepo inodzorwa kana mabhegi epurasitiki), sezvo tembiricha nehunyoro zvinogona kukanganisa kunyudzwa uye kushanda zvakanaka kwe1-MCP.

Pari zvino, ndinofunga kuti munhu wese anenge afunga nezvemubvunzo mumwe chete:

Kushandisa 1-methylcyclopropene kune njodzi kumuviri wemunhu here?

1-methylcyclopropene haina njodzi kumuviri wemunhu kana ikashandiswa zvine mwero, uye kuchengetedzeka kwayo kwakazivikanwa nemasangano ane masimba epasi rose. Ingava chepfu yakanyanya, migumisiro yehutano kwenguva refu kana njodzi dzasara, zvese zviri mukati mehuwandu hunogamuchirwa. Vatengi havafanirwe kunetseka pavanodya zvigadzirwa zvekurima zvakarapwa ne1-MCP, uye vanoshanda vanofanirwa kutevedzera nzira dzekuchengetedza kuti vadzivise njodzi yekusangana nebasa. Chinhu chikuru chehunyanzvi uhwu chiri mukuwedzera nguva yekutsva kwezvigadzirwa zvekurima kuburikidza nenzira dzesainzi pane kuisa njodzi dzinogona kuitika.

Kukosha kukuru kwe1-methylcyclopropene kuri mukudzora zvakanyatsonaka mhedzisiro ye ethylene mumuviri kuti ichengetedze zvigadzirwa zvekurima uye kutarisira kukura kwezvirimwa. 1-methylcyclopropene yave nzira yakakosha yekurapa mushure mekukohwa mukurima kwemazuva ano, kunyanya iine mabhenefiti makuru mukuwedzera hupenyu hwemichero nemaruva uye kuvandudza mhando yemichero nemaruva. ​​Kunyanya muzhizha, mamiriro ekupisa kwakanyanya uye hunyoro hwakawanda muzhizha anogona kukurumidza kukuvadza michero. Kuchengetedza kwesainzi kunoda kugadzira mapurani pamwe chete nehunhu hwemichero nezvinhu zvakatipoteredza.

Kunyanya muzhizha, mamiriro ekunze anodziya zvakanyanya uye ane hunyoro hwakawanda muzhizha anogona kukurumidza kukuvadza michero. Kuchengetedza kwesainzi kunoda kugadzira mapurani pamwe chete nehunhu hwemichero nezvinhu zvezvakatipoteredza. Isu tiri nyanzvi.Vatengesi ve1-methylcyclopropene. 1-MCP powder isarudzo yakanaka kwauri.
