1-Methylcyclopropene(yofupikitsidwa ngati 1-MCP) CAS 3100-04-7, ndi molekyulu yaying'ono yokhala ndi kapangidwe kozungulira ndipo imagwiritsidwa ntchito kwambiri pantchito yosunga zinthu zaulimi chifukwa cha ntchito yake yapadera pakulamulira thupi la zomera.

1-Methylcyclopropene (1-MCP) ndi mankhwala omwe ali ndi njira yapadera yogwirira ntchito ndipo amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, makamaka paulimi ndi kusunga chakudya. Izi ndi zomwe zimagwiritsidwa ntchito kwambiri komanso zina zokhudzana nazo:

Gawo la ulimi ndi kusunga zipatso

1. Letsani mphamvu ya ethylene ndikuwonjezera nthawi yatsopano ya zipatso

Mfundo Yogwirira Ntchito: Ethylene ndi mahomoni ofunikira kwambiri pakukhwima ndi ukalamba wa zipatso za zomera. 1-MCP imatha kumangirira mosasinthika ku ma ethylene receptors, kuletsa kutumiza kwa chizindikiro cha ethylene, motero kuchedwetsa kukhwima, kufewa ndi ukalamba wa zipatso.

Zochitika zogwiritsira ntchito:

Kusunga zipatso zosiyanasiyana: monga maapulo, mapeyala, nthochi, kiwi, mango, sitiroberi, ndi zina zotero. Mwachitsanzo, ngati maapulo apatsidwa 1-MCP atangokolola, amatha kutalikitsa nthawi yawo yosungiramo zinthu mufiriji kapena kutentha kwa chipinda, ndikusunga kulimba ndi kapangidwe kake.

Kuletsa matenda a thupi pambuyo pokolola: Kuchepetsa mavuto monga kufiira kwa masamba ndi kuwola kwa zipatso zomwe zimayambitsidwa ndi ethylene (monga matenda a madontho akuda mu nthochi).

Ubwino: Poyerekeza ndi zinthu zoyamwitsa ethylene (monga potaziyamu permanganate),1-MCPimakhala ndi mphamvu yokhalitsa komanso yogwira mtima, ndipo imafuna mlingo wochepa (nthawi zambiri ppm).

2. Kulamulira kukalamba kwa maluwa ndi zomera zokongoletsera

Kugwiritsa ntchito poteteza maluwa odulidwa: Kukulitsa nthawi ya maluwa odulidwa monga maluwa a ...

Kusamalira zomera m'miphika: Kuletsa kukalamba msanga kwa zomera zokongoletsera za m'nyumba (monga Phalaenopsis) ndikusunga mawonekedwe okongola a chomera.

Munda wa Ulimi ndi Kulima Zomera

1. Yang'anirani kukula ndi chitukuko cha zomera

Kuchedwetsa kukalamba kwa masamba: Amagwiritsidwa ntchito pochiza ndiwo zamasamba monga broccoli ndi letesi pambuyo pokolola kuti zisunge mtundu wawo wobiriwira komanso watsopano.

Kuwongolera kukhwima kwa mbewu: Polima zipatso monga tomato ndi tsabola, mankhwala a 1-MCP amagwiritsidwa ntchito kuti zipatso zikhwima mofanana, zomwe zimathandiza kukolola ndi kukonza zinthu pamodzi.

2. Chepetsani kupsinjika kwa zomera

Kulimbana ndi kupsinjika maganizo: Pakachitika kupsinjika maganizo kapena kupsinjika kwa chilengedwe (monga kutentha kwambiri kapena kotsika), kumachepetsa kupsinjika komwe kumachitika chifukwa cha ethylene m'zomera, ndipo kumachepetsa chikasu ndi kugwa kwa masamba.

Ntchito zina zomwe zingatheke

1. Kuchiza pasadakhale mumakampani ogulitsa chakudya

1-Methylcyclopropene imagwiritsidwa ntchito kusunga zipatso zatsopano (monga zidutswa za apulo ndi zidutswa za mapeyala), kuchedwetsa kukhuthala ndi kufiira, ndikuwonjezera nthawi yosungira.

2. Kafukufuku wa sayansi ndi kafukufuku woyesera

Monga chida chophunzirira momwe ethylene imagwirira ntchito, imagwiritsidwa ntchito mu physiology ya zomera ndi ma molecular biology kuti ifufuze njira yowongolera njira yolumikizirana ya ethylene.

Malangizo Ogwiritsira Ntchito

Kutsatira nthawi:1-Methylcyclopropeneayenera kugwiritsidwa ntchito asanatulutse ethylene kuchokera ku chipatso kapena chomera (monga mwamsanga mutakolola) kuti agwire bwino ntchito. Ngati chipatso chafika kumapeto kwa nthawi yokhwima, zotsatira zake zidzachepa.

Kuwongolera Mlingo: Mbewu zosiyanasiyana zimakhala ndi mphamvu yosiyana ku 1-Methylcyclopropene 1-MCP (mwachitsanzo, mtundu wa zipatso zomwe zimasinthidwa umakhala wovuta kwambiri). Kuchuluka kwa zipatso zomwe zimayikidwa kuyenera kusinthidwa malinga ndi mtundu wa zipatso kuti zipewe kukoma kosazolowereka komwe kumachitika chifukwa cha kuchuluka kwa zipatso (monga "ufa" wa maapulo).

Mkhalidwe wa chilengedwe: Kukonza kuyenera kuchitika pamalo otsekedwa (monga chipinda chosungiramo zinthu m'mlengalenga wolamulidwa kapena matumba apulasitiki), chifukwa kutentha ndi chinyezi zimatha kusokoneza kuyamwa ndi kugwira ntchito bwino kwa 1-MCP.

Pofika pano, ndikuganiza kuti aliyense adzakhala ataganizira funso limodzi:

Kodi kugwiritsa ntchito 1-methylcyclopropene ndikovulaza thupi la munthu?

1-methylcyclopropene ndi yopanda vuto kwa thupi la munthu ngati ikugwiritsidwa ntchito moyenera, ndipo mabungwe odziwika padziko lonse lapansi azindikira chitetezo chake. Kaya ndi poizoni woopsa, zotsatirapo zathanzi kwa nthawi yayitali kapena zoopsa zotsala, zonse zili mkati mwa mulingo woyenera. Ogula sayenera kuda nkhawa akamadya zinthu zaulimi zomwe zapatsidwa 1-MCP, ndipo ogwiritsa ntchito amangofunika kutsatira njira zodzitetezera kuti apewe chiopsezo chogwiritsidwa ntchito. Ubwino waukulu wa ukadaulo uwu uli pakuwonjezera nthawi yatsopano ya zinthu zaulimi kudzera munjira zasayansi m'malo mobweretsa zoopsa zomwe zingachitike.

Phindu lalikulu la 1-methylcyclopropene lili pakuwongolera bwino momwe ethylene imakhudzira thupi kuti zinthu zaulimi zisungidwe komanso kusamalira kukula kwa zomera. 1-methylcyclopropene yakhala njira yofunika kwambiri yochizira matenda pambuyo pokolola mu ulimi wamakono, makamaka kukhala ndi ubwino waukulu pakuwonjezera nthawi yogwiritsira ntchito komanso kukonza ubwino wa zipatso ndi maluwa. Makamaka m'chilimwe, malo otentha kwambiri komanso chinyezi chambiri m'chilimwe amatha kufulumizitsa kuwonongeka kwa zipatso mosavuta. Kusunga kwasayansi kumafuna kupanga mapulani pamodzi ndi makhalidwe a zipatso ndi zinthu zachilengedwe.

Makamaka nthawi yachilimwe, malo otentha kwambiri komanso chinyezi chambiri nthawi yachilimwe amatha kufulumizitsa kuwonongeka kwa zipatso. Kusunga kwasayansi kumafuna kupanga mapulani ogwirizana ndi makhalidwe a zipatso ndi zinthu zachilengedwe. Ndife akatswiri.Ogulitsa 1-methylcyclopropeneUfa wa 1-MCP ndi chisankho chabwino kwa inu.
