1-Methylcyclopropene(yofupikitsidwa ngati 1-MCP) CAS 3100-04-7, ndi molekyulu yaying'ono yokhala ndi mawonekedwe ozungulira ndipo imagwiritsidwa ntchito kwambiri poteteza zokolola zaulimi chifukwa cha gawo lake lapadera pakuwongolera zachilengedwe.

1-Methylcyclopropene (1-MCP) ndi gulu lomwe lili ndi njira yapadera yochitira zinthu ndipo lili ndi ntchito zofunika m'madera ambiri, makamaka paulimi ndi kusunga chakudya. Zotsatirazi ndizomwe zimagwiritsidwa ntchito ndi zambiri zokhudzana nazo:

Munda waulimi ndi kusunga zipatso

1. Imalepheretsa mphamvu ya ethylene ndikukulitsa nthawi yakutsitsimuka kwa zipatso

Mfundo yoyendetsera: Ethylene ndi mahomoni ofunikira pakucha komanso kununkhira kwa zipatso. 1-MCP imatha kumangirira mosasinthika ku ma ethylene receptors, kuletsa kufalikira kwa ma ethylene, ndipo potero kuchedwetsa kucha, kufewetsa ndi kumera kwa zipatso.

Zochitika zantchito:

Kusungidwa kwa zipatso zosiyanasiyana: monga maapulo, mapeyala, nthochi, kiwi, mango, sitiroberi, ndi zina zotero. Mwachitsanzo, ngati maapulo amathandizidwa ndi 1-MCP atathyola, amatha kuwonjezera moyo wawo wa alumali pa firiji kapena kutentha kwa chipinda, ndikusunga kulimba ndi mawonekedwe a thupi.

Chepetsani matenda obwera pambuyo pokolola: Chepetsani mavuto monga Browning ndi kuwola kwa zipatso chifukwa cha ethylene (monga matenda a black spot mu nthochi).

Ubwino wake: Poyerekeza ndi zinthu zachikhalidwe za ethylene (monga potaziyamu permanganate),1-MCPimakhala ndi zotsatira zokhalitsa komanso zogwira mtima, ndipo imafuna mlingo wochepa (nthawi zambiri ppm yochepa).

2. Kuwongolera kukalamba kwa maluwa ndi zomera zokongola

Amagwiritsidwa ntchito poteteza maluwa odulidwa: Wonjezerani moyo wa mphika wa maluwa odulidwa monga maluwa, ma carnations ndi maluwa, ndikuchedwetsa kufota ndi kufota kwa maluwa.

Kusamalira mbewu zokhala ndi miphika: Kuletsa kukalamba msanga kwa mbewu zokongoletsa zamkati (monga Phalaenopsis) ndikusunga mawonekedwe okongola.

Munda Wolima Horticulture ndi Zomera

1. Kuwongolera kukula ndi kukula kwa zomera

Kuchedwetsa ukalamba wa masamba: Amagwiritsidwa ntchito pochiza masamba atakololedwa monga broccoli ndi letesi kuti asunge mtundu wawo wobiriwira wa emarodi komanso kutsitsimuka.

Kuwongolera kukhwima kwa mbewu: Polima zipatso monga tomato ndi tsabola, mankhwala a 1-MCP amatengedwa kuti apangitse kukhwima kwa chipatsocho kukhala chofanana, kuthandizira kukolola ndi kukonza pakati.

2. Chepetsani kuyankha kwa kupsinjika kwa mbewu

Kulimbana ndi kupsinjika kwamphamvu: Pakuyenda kapena kupsinjika kwa chilengedwe (monga kutentha kwambiri kapena kutsika), kumachepetsa kupsinjika komwe kumabwera chifukwa cha ethylene muzomera, komanso kumachepetsa chikasu cha masamba ndi kugwa.

Mapulogalamu ena Otheka

1. Kusamala m'makampani azakudya

1-Methylcyclopropene imagwiritsidwa ntchito posungira zipatso zatsopano (monga magawo a maapulo ndi ma peyala), kuchedwetsa oxidation ndi Browning, ndikuwonjezera moyo wa alumali.

2. Kafukufuku wa sayansi ndi kafukufuku woyesera

Monga chida chophunzirira momwe amagwirira ntchito ethylene, amagwiritsidwa ntchito muzoyeserera zasayansi yazachilengedwe ndi ma cell biology kuti afufuze njira yoyendetsera njira yolumikizira ethylene.

Kusamala Kugwiritsa Ntchito

Nthawi:1-Methylcyclopropeneiyenera kugwiritsidwa ntchito musanatulutse ethylene ku chipatso kapena chomera (monga mwamsanga mutatha kutola) kuti ikhale yabwino. Ngati chipatso walowa mochedwa siteji yakucha, mankhwala zotsatira adzachepa.

Kuwongolera Mlingo: Mbewu zosiyanasiyana zimakhala ndi sensitito yosiyana ku 1-Methylcyclopropene 1-MCP (mwachitsanzo, mtundu wa zipatso umakhudzidwa kwambiri). Kuphatikizika kwa ntchito kuyenera kusinthidwa molingana ndi kusiyanasiyana kuti tipewe kukoma kwa zipatso zomwe zimayambitsidwa ndi kuchuluka kwa mlingo (monga "ufa" wa maapulo).

Zachilengedwe: Chithandizocho chiyenera kuchitidwa pamalo otsekedwa (monga malo osungiramo mlengalenga kapena matumba apulasitiki), chifukwa kutentha ndi chinyezi zingakhudze kutengeka ndi kuchitapo kanthu kwa 1-MCP.

Pofika pano, ndikuganiza kuti aliyense ali ndi funso limodzi:

Kodi kugwiritsa ntchito 1-methylcyclopropene ndi kovulaza thupi la munthu?

1-methylcyclopropene ilibe vuto kwa thupi la munthu pakagwiritsidwe ntchito moyenera, ndipo chitetezo chake chadziwika ndi mabungwe ovomerezeka padziko lonse lapansi. Kaya ndi chiwopsezo chachikulu, zotsatira za thanzi lanthawi yayitali kapena zoopsa zotsalira, zonse zili m'gulu lovomerezeka. Ogula asamade nkhawa akamadya zinthu zaulimi zomwe zathandizidwa ndi 1-MCP, ndipo ogwiritsira ntchito amayenera kutsatira njira zotetezera kuti apewe ngozi yokhudzana ndi ntchito. Ubwino waukulu waukadaulowu wagona pakukulitsa nthawi yatsopano yazaulimi pogwiritsa ntchito njira zasayansi m'malo mobweretsa zoopsa zomwe zingachitike.

Phindu lalikulu la 1-methylcyclopropene lagona pakuwongolera bwino momwe thupi la ethylene limakhudzira chitetezo chaulimi ndikuwongolera kukula kwa mbewu. 1-methylcyclopropene yakhala njira yofunikira yaukadaulo yochizira pambuyo pokolola muulimi wamakono, makamaka kukhala ndi maubwino owonjezera moyo wa alumali ndikuwongolera zipatso ndi maluwa. Makamaka m'chilimwe, malo otentha kwambiri komanso otentha kwambiri m'chilimwe amatha kufulumira kuwonongeka kwa zipatso. Kutetezedwa kwasayansi kumafuna kupanga mapulani ophatikizana ndi mawonekedwe a zipatso ndi zinthu zachilengedwe.

Makamaka m'chilimwe, malo otentha kwambiri komanso otentha kwambiri m'chilimwe amatha kufulumira kuwonongeka kwa zipatso. Kutetezedwa kwasayansi kumafuna kupanga mapulani ophatikizana ndi mawonekedwe a zipatso ndi zinthu zachilengedwe. Ndife akatswiri1-methylcyclopropene othandizira. 1-MCP ufa ndi chisankho chabwino kwa inu.
