Katswiri Wopereka Fakitale 1-MCP 1-Methylcyclopropene CAS 3100-04-7
1-Methylcyclopropene, yomwe chidule chake ndi 1-MCP, ili ndi CAS 3100-04-7. 1-Methylcyclopropene ndi chinthu chofunikira kwambiri chowongolera kukula kwa zomera. 1-MCP imatha kumangirira ku ma receptors a ethylene ndipo imakhala ndi mphamvu yolimba yomangirira kuposa ethylene. Ufa wa 1-mcp ukhoza kugwira ntchito mosasinthika pa ma receptors a ethylene ndikuletsa kumangirira kwa ethylene ku ma receptors ake. Izi zitha kuletsa machitidwe osiyanasiyana okhudzana ndi thupi komanso a biochemical okhudzana ndi kukhwima kwa zipatso chifukwa cha ethylene, kuchedwetsa kukhwima, ndikukwaniritsa zotsatira za kusungidwa.
Ili ndi nthawi yayitali yosungira. Malingana ngati 1-MCP ilipo m'chilengedwe, chipatso sichingapse pambuyo pake. Chimagwira ntchito kwambiri ndipo chimatha kugwira ntchito pamlingo wa 1ppm (zigawo pa miliyoni) mumlengalenga. 1-methylcyclopropene, yopanda poizoni komanso yopanda kuipitsa, ndi mpweya wosasunthika womwe susiya zotsalira mutagwiritsa ntchito. 1-mcp sikhudza ubwino wa zipatso, imatha kuchedwetsa kuchepa kwa kuuma kwa zipatso ndi kuchuluka kwa asidi woti titha kuigwiritsa ntchito, kusunga kukoma kwabwino, ndikuchepetsa kutayika kwa michere. 1-MCP ikhozanso kuletsa matenda ofala omwe amapezeka panthawi yosungidwa kwa zipatso, monga matenda a khungu la tiger pa maapulo ndi matenda akuda pa mapeyala. 1-Methylcyclopropene ndi mankhwala oletsa kukula kwa zomera zopangidwa, omwe akhala akugwiritsidwa ntchito kwambiri m'malonda.

1. Kusunga zipatso: Kuchedwetsa kucha, kuchepetsa matenda ndi kutayika kwa michere
Pa zipatso zomwe zimapanga ethylene zokha (kapena zomwe zimakhudzidwa ndi ethylene), 1-MCP imatha kusunga bwino zipatso ndipo ndi imodzi mwa ntchito zofunika kwambiri posungira ndi kutumiza m'masitolo. 1-Methylcyclopropene imatha kuletsa kukhwima kwawo mwachangu (monga chikasu cha nthochi komanso kufewa kwa mnofu wa mango), kuthetsa ululu wonyamulira womwe "umawonongeka mosavuta mutakolola" zipatso zotere. Wonjezerani kuchuluka kwa malonda.
2. Kusunga masamba: Sungani kuti aziuma komanso atsopano, ndikuchepetsa kufota ndi kuwola
1-Methylcyclopropene imagwiritsidwa ntchito makamaka pa ndiwo zamasamba zomwe zimafunika kusunga mawonekedwe olimba komanso olimba kapena zomwe zimataya madzi ndikufota. Ndi yoyenera makamaka mitundu yomwe imapumabe ikatha kukolola ndipo imakhudzidwa mosavuta ndi ethylene, zomwe zimapangitsa kuti khungu la zipatso likhale lolimba. 1-methylcyclopropene imapewa kusweka kwa mnofu kapena kufooka kwa kukoma, ndipo nthawi yomweyo imachepetsa kuwola komwe kumachitika chifukwa cha tizilombo toyambitsa matenda.
3. Kusunga maluwa: Kuonjezera nthawi yowonera maluwa ndikuchepetsa kugwa kwa maluwa ndi maluwa
Pa maluwa odulidwa kapena opangidwa m'miphika omwe ali ndi vuto la ethylene, 1-MCP imatha kuchepetsa kupangika kwa maluwa ndi kutayika kwa maluwa, zomwe zimapangitsa kuti maluwawo azikongoletsa kwambiri. Mitundu yogwiritsidwa ntchito imaphatikizapo kuchepetsa kutayika panthawi yonyamula kapena kuyika maluwa. Ufa wa 1-mcp ndi woyenera kwambiri ponyamula maluwa atsopano odulidwa kutali komanso m'masitolo ogulitsa maluwa.
4. Ntchito zina zothandizira
Kuwonjezera pa kusungidwa mwachindunji, 1-MCP ingathandizenso kupanga mbewu. Pa nthawi yobzala mbewu zina za m'munda (monga zomera zokongoletsera), kuchuluka kochepa kwa 1-MCP kungagwiritsidwe ntchito kulamulira kakulidwe ka zomera, kupewa kuphuka msanga kapena kukalamba. Ufa wa 1-mcp ungathandize kukulitsa nthawi yosungiramo mbewu mutakolola ndikuchepetsa kuwonongeka kwa zosakaniza zogwira ntchito za mankhwala ena aku China omwe ndi osavuta kugwiritsa ntchito.
1. Chiyero: Muyezo wa makampani a 1-MCP ndi 3.3%, koma tikhoza kufika pa 3.7%.
2. Tikhoza kupereka ma dose ang'onoang'ono, mapaketi ang'onoang'ono a 0.035%, kuti tigwiritse ntchito pa mashelufu a masitolo akuluakulu kapena m'mabokosi a zipatso.
3. Chitetezo cha Katundu: 1-MCP ndi molekyulu ya mpweya yomwe imasungunuka kwathunthu ikakonzedwa, osasiya zotsalira za mankhwala pa chinthucho.
Ndife akatswiri ogulitsa mankhwala a 1-methylcyclopropene. Ngati mukufuna kugula mankhwala a CAS 3100-04-71-mcp, chonde titumizireni uthenga. Tikuyembekezera kugwira nanu ntchito limodzi.
