1-Methylcyclopropene(whakarāpopototia ko 1-MCP) Ko te CAS 3100-04-7, he matū ngota iti me te hanganga huringa, ā, e whakamahia whānuitia ana i roto i te mara o te tiaki hua ahuwhenua nā tōna tūranga ahurei i roto i te whakahaere ā-tinana o ngā tipu.
He matū ahurei te 1-Methylcyclopropene (1-MCP) me te tikanga mahi, ā, he nui ngā whakamahinga i roto i ngā mara maha, inā koa i roto i te ahuwhenua me te tiaki kai. Ko ngā whakamahinga matua me ngā taipitopito e pā ana ki ēnei:
Te mara o te ahuwhenua me te tiaki hua
1. Ārai i te pānga o te ethylene me te whakaroa i te wā hou o ngā hua
Mātāpono mahi: Ko te ethylene te homoni matua mō te pakari me te koroheketanga o ngā hua tipu. Ka taea e te 1-MCP te herea tonu ki ngā kaiwhakawhiwhi ethylene, te aukati i te tuku tohu ethylene, ā, nā reira ka whakaroa i ngā tukanga pakari, whakangawari me te koroheketanga o ngā hua.
Ngā horopaki tono:
Te tiaki i ngā momo hua: pērā i te aporo, te pea, te panana, te kiwi, te māngo, te rōpere, me ētahi atu. Hei tauira, ki te rongoatia ngā aporo ki te 1-MCP i muri i te kohi, ka roa ake te ora o te pupuri i roto i te pouaka whakamātao, i te pāmahana rūma rānei, ā, ka mau tonu te pakari me te kakano o te kikokiko.
Te whakahaere i ngā mate ā-tinana i muri i te kotinga: Te whakaiti i ngā raruraru pēnei i te parauri me te pirau o ngā hua i puta mai i te ethylene (pēnei i te mate ira pango i roto i ngā panana).
Ngā Painga: Ki te whakatauritea ki ngā mea mimiti ethylene tuku iho (pērā i te pāhare pākawa waro),1-MCPhe roa ake te pānga, he whai hua ake hoki, ā, he iti ake te horopeta e hiahiatia ana (he torutoru ppm te nuinga o te wā).
2. Whakahaere i te koroheketanga o ngā putiputi me ngā tipu whakapaipai
Whakamahia hei tiaki i ngā putiputi kua tapahia: Ka roa ake te ora o ngā putiputi kua tapahia pērā i te rōhi, te karonati me te rengarenga, ā, ka whakaroa i te memenge me te memeha o ngā rau.
Te whakahaere i ngā tipu i roto i ngā kohua: Ārai i te koroheketanga wawe o ngā tipu whakapaipai o roto (pērā i te Phalaenopsis) me te pupuri i te āhua ataahua o te tipu.
Te Mara Whakatipu Māra me te Whakatipu Tipu
1. Whakahaere i te tipu me te whanaketanga o ngā tipu
Te whakaroa i te koroheketanga o ngā huawhenua: Ka whakamahia mō te maimoatanga i muri i te kotinga o ngā huawhenua pēnei i te broccoli me te rētihi kia mau tonu ai te tae kakariki me te hou.
Te whakahaere i te ōritetanga o te pakari o te hua: I roto i te whakatipu hua pēnei i te tōmato me te pepa, ka whakamahia te maimoatanga 1-MCP kia ōrite ake te pakari o te hua, kia māmā ake ai te hauhake me te tukatuka pokapū.
2. Whakaitihia ngā urupare ahotea o ngā tipu
Te ātete ki te ahotea kua whakapakaritia: I raro i te ahotea o te kawe waka, i te ahotea taiao rānei (pērā i te pāmahana teitei, iti rānei), ka whakaitihia te urupare ahotea i puta mai i te ethylene i roto i ngā tipu, ā, ka whakaitihia te kōwhai me te hinga o ngā rau.
Ētahi atu tono pea
1. Te tukatuka i mua i te ahumahi kai
E whakamahia ana te 1-Methylcyclopropene hei tiaki i ngā hua hou kua tapahia (pērā i ngā poro aporo me ngā poraka pea), hei whakaroa i te waikura me te parauri, hei whakaroa hoki i te ora o te rokiroki.
2. Rangahau pūtaiao me te rangahau whakamātautau
Hei taputapu matū mō te ako i te tikanga mahi a te ethylene, e whakamahia ana i roto i ngā whakamātautau koiora tipu me ngā whakamātautau koiora ngota hei tūhura i te tikanga whakahaere o te ara tohu ethylene.
Ngā Whakatūpato mō te Whakamahinga
Te Wā:1-Methylcyclopropeneme whakamahi i mua i te tukunga o te ethylene mai i te hua, i te tipu rānei (pērā i te wā e taea ai i muri i te kohi) kia pai ai te hua. Mēnā kua tae te hua ki te wā mutunga o te pakari, ka heke te hua o te maimoatanga.
Te whakahaere inenga: He rerekē te aro o ngā hua rerekē ki te 1-Methylcyclopropene 1-MCP (hei tauira, he aro ake te momo hua whakawhiti). Me whakarerekē te kukū o te tono kia rite ki te momo hei karo i te reka rerekē o te hua i puta mai i te nui rawa o te inenga (pērā i te "paura" o ngā aporo).
Ngā āhuatanga taiao: Me whakahaere te maimoatanga i roto i tētahi taiao kati (pērā i tētahi rūma rokiroki hau whakahaeretia, i ngā putea kirihou rānei), nā te mea ka pā te pāmahana me te haumākū ki te mimiti me te whai huatanga o te mahi a te 1-MCP.
I tēnei wā, ki taku whakaaro kua whakaarohia e te katoa tētahi pātai:
He kino te whakamahinga o te 1-methylcyclopropene ki te tinana tangata?
Kāore te 1-methylcyclopropene e kino ki te tinana tangata i raro i ngā tikanga whakamahinga tika, ā, kua mōhiotia tōna haumaru e ngā umanga mana o te ao. Ahakoa he paitini nui, he pānga hauora mō te wā roa, he mōrearea toenga rānei, kei roto katoa i te awhe e whakaaetia ana. Kāore he take e manukanuka ai ngā kaihoko i te wā e kai ana i ngā hua ahuwhenua kua rongoatia ki te 1-MCP, ā, me whai noa ngā kaiwhakahaere i ngā tikanga haumaru hei karo i te mōrearea o te tūponotanga mahi. Ko te painga matua o tēnei hangarau ko te whakaroa i te wā hou o ngā hua ahuwhenua mā roto i ngā tikanga pūtaiao, kaua ki te whakauru i ngā mōrearea haumaru pea.
Ko te uara matua o te 1-methylcyclopropene kei roto i te whakahaere tika i ngā pānga ā-tinana o te ethylene kia tutuki ai te tiaki i ngā hua ahuwhenua me te whakahaere i te tipu o ngā tipu. Kua noho te 1-methylcyclopropene hei huarahi hangarau nui mō te maimoatanga i muri i te kotinga i roto i te ahuwhenua hou, inā koa he painga nui ki te whakaroa i te roa o te wā rokiroki me te whakapai ake i te kounga o ngā hua me ngā putiputi. Ina koa i te raumati, ka taea e te taiao pāmahana teitei me te haumākū teitei i te raumati te tere ake te pirau o ngā hua. Ko te tiaki pūtaiao me whakatakoto mahere me te whakakotahi i ngā āhuatanga o ngā hua me ngā āhuatanga taiao.
Ina koa i te raumati, ka tere ake te pirau o ngā hua nā te pāmahana teitei me te makuku nui i te raumati. Me whakatakoto mahere te tiaki pūtaiao me ngā āhuatanga o ngā hua me ngā āhuatanga taiao. He ngaio mātou.Ngā kaiwhakarato 1-methylcyclopropeneHe kōwhiringa pai te paura 1-MCP māu.
