1-Methylcyclopropene(yakapfupikiswa se1-MCP) CAS 3100-04-7, idiki molecule musanganiswa ine cyclic chimiro uye rinoshandiswa zvakanyanya mumunda wekuchengetedza zvigadzirwa zvekurima nekuda kwechinzvimbo chayo chakasiyana mukudyara physiological regulation.

1-Methylcyclopropene (1-MCP) isanganiswa ine yakasarudzika nzira yekuita uye ine yakakosha maapplication mundima dzakawanda, kunyanya mukurima nekuchengetedza chikafu. Izvi zvinotevera mashandisirwo ayo makuru uye zvine chekuita neruzivo:

Munda wekurima uye kuchengetedza michero

1. Kudzivisa kushanda kwe ethylene uye kuwedzera nguva yekutsva kwemichero

Nheyo yekuita: Ethylene ihomoni yakakosha yekuibva uye senescence yemuchero wezvirimwa. 1-MCP inogona kusunga zvisingachinjiki kune ethylene receptors, kudzivirira ethylene chiratidzo kutapurirana, uye nekudaro kunonoka kuibva, kupfava uye senescence maitiro emichero.

Mamiriro ekushandisa:

Kuchengetedzwa kwezvibereko zvakasiyana-siyana: zvakadai semaapuro, mapeari, mabhanana, kiwis, mango, sitirobheni, etc. Somuenzaniso, kana maapuro akabatwa ne 1-MCP mushure mekutanha, inogona kuwedzera zvakanyanya hupenyu hwavo hwepasherufu pafiriji kana tembiricha yekamuri, uye kuchengetedza kusimba uye kuumbwa kwenyama.

Kudzora zvirwere zvemuviri mushure mekukohwa: Deredza matambudziko akaita seBrowning uye kuora kwemichero kunokonzerwa ne ethylene (senge black spot disease mumabanana).

Zvakanakira: Zvichienzaniswa nezvinomwisa ethylene zvechinyakare (zvakadai sepotassium permanganate),1-MCPine mhedzisiro inogara uye inoshanda, uye inoda yakaderera dosage (kazhinji mashoma ppm).

2. Kugadzirisa kukwegura kwemaruva nemiti yekushongedza

Inoshandiswa pakuchengetedza maruva akachekwa: Wedzera hupenyu hwevhasi yemaruva akachekwa semarosi, carnations uye maruva, uye kunonoka kusvava uye kupera kwemapetali.

Potted plant management: Dzivirira kuchembera kusati kwasvika kwezvirimwa zvemukati zvekushongedza (senge Phalaenopsis) uye chengetedza chimiro chechirimwa chinoyevedza.

Horticulture uye Plant Kurimwa Munda

1. Kudzora kukura uye kukura kwezvirimwa

Kunonotsa kuchembera kwemuriwo: Inoshandiswa kurapa mushure mekukohwa kwemiriwo senge broccoli uye lettuce kuchengetedza ruvara rwegirinhi rweemerald uye kutsva.

Kudzora kuenderana kwekukura kwechirimwa: Mukurima michero yakaita sematomatisi nemhiripiri, kurapwa kwe1-MCP kunogamuchirwa kuita kuti muchero uwedzere yunifomu, kufambisa kukohwa pakati uye kugadzirisa.

2. Deredza mhinduro dzekushushikana kwezvirimwa

Enhanced stress resistance: Pasi pekufambisa kana kushushikana kwezvakatipoteredza (sekupisa kana kupisa kwakadzika), kunoderedza kushushikana kunokonzerwa ne ethylene muzvirimwa, uye kunoderedza kutsvuka kwemashizha nekudonha.

Zvimwe Zvingango shandiswa

1. Pretreatment muindasitiri yezvekudya

1-Methylcyclopropene inoshandiswa kuchengetedza michero yakachena-yakatemwa (yakadai semaapuro zvimedu uye pear chunks), kunonoka oxidation uye Browning, uye kuwedzera hupenyu hwesherufu.

2. Tsvakurudzo yesainzi uye ongororo yekuedza

Sechishandiso chemushonga wekudzidza maitiro echiito che ethylene, inoshandiswa muchirimwa physiology uye molecular biology kuyedza kuongorora nzira yekudzora ye ethylene signing nzira.

Chengetedzo Yekushandisa

Nguva:1-Methylcyclopropeneinofanira kushandiswa kusati kwasunungurwa ethylene kubva kumuchero kana chirimwa (sekunge nokukurumidza sezvinobvira mushure mekutora) kuitira zvakanakisisa. Kana chibereko chapinda muchikamu chekupedzisira chekuibva, mushonga wekurapa uchaderera.

Dosage control: Mbeu dzakasiyana dzine sensitito yakasiyana kune 1-Methylcyclopropene 1-MCP (somuenzaniso, mhando yekushandura yemuchero inonyanya kuoma). Iko kusungirirwa kwekushandisa kunofanirwa kugadziridzwa zvinoenderana nemhando dzakasiyana kuti udzivise kunhuhwirira kwemuchero kunokonzerwa nekunyanyisa dosage (senge "powderization" yemaapuro).

Mamiriro ezvakatipoteredza: Kurapa kunofanirwa kuitwa munzvimbo yakavharwa (senge inodzorwa mukamuri yekuchengetera mhepo kana mabhegi epurasitiki), sezvo tembiricha uye hunyoro zvinogona kukanganisa adsorption uye kuita kwekuita kwe1-MCP.

Parizvino, ndinofunga munhu wese achange afunga mubvunzo mumwe chete:

Iko kushandiswa kwe1-methylcyclopropene kunokuvadza kumuviri wemunhu?

1-methylcyclopropene haina ngozi kumuviri wemunhu pasi pemamiriro ekushandiswa anonzwisisika, uye kuchengetedzeka kwayo kwave kuchizivikanwa nemasangano ane masimba epasirese. Ingave iri huturu hwehupfu, hutano hwenguva refu kana njodzi dzasara, zvese zviri mukati meiyo inogamuchirwa renji. Vatengi havafanire kunetseka kana vachidya zvigadzirwa zvekurima zvakabatwa ne1-MCP, uye vashandisi vanongoda kutevedzera nzira dzekuchengetedza kudzivirira njodzi yekufumurwa pabasa. Mukana mukuru wetekinoroji iyi uri mukuwedzera nguva yekutsva kwezvigadzirwa zvekurima kuburikidza nenzira dzesainzi pane kuunza njodzi dzinogona kuitika.

Iyo yakakosha kukosha kwe1-methylcyclopropene iri mukunyatso kudzora maitiro ephysiological ethylene kuwana kuchengetedza kwezvigadzirwa zvekurima uye manejimendi ekukura kwezvirimwa. 1-methylcyclopropene yave yakakosha tekinoroji nzira yekurapa mushure mekukohwa mukurima kwemazuva ano, kunyanya kuve nemabhenefiti akakosha mukuwedzera hupenyu hwesherufu nekuvandudza mhando yemichero nemaruva. Kunyanya muzhizha, nzvimbo yepamusoro-yepamusoro uye yakakwirira-yakadzika muzhizha inogona kukurumidza kukurumidza kuparara kwemichero. Kuchengetedzwa kwesainzi kunoda kuumba zvirongwa zvakabatana nehunhu hwemichero uye zvakatipoteredza.

Kunyanya muzhizha, nzvimbo yepamusoro-yepamusoro uye yakakwirira-yakadzika muzhizha inogona kukurumidza kukurumidza kuparara kwemichero. Kuchengetedzwa kwesainzi kunoda kuumba zvirongwa zvakabatana nehunhu hwemichero uye zvakatipoteredza. Isu tiri nyanzvi1-methylcyclopropene vatengesi. 1-MCP poda isarudzo yakanaka kwauri.
