Te tipu o te tipuHe mea nui te aukati i te tipu o ngā hua. Mā te whakahaere i te tipu tipu me te tipu uri o ngā hua, ka taea te whiwhi kounga pai ake me te hua nui ake. Ko ngā mea e aukati ana i te tipu o ngā tipu ko te paclobutrazol, uniconazole, peptidomimetics, chlormethalin, me ētahi atu. Hei momo aukati tipu hou, kua aro nui te prohexadione calcium ki te mākete i ngā tau tata nei, ā, kua tere te piki haere o te maha o ngā rēhitatanga. Kātahi,paclobutrazol, niconazole, paroxamine, chlorhexidine, me te prohexadione calcium, he aha ngā rerekētanga o ngā whakamahinga mākete o ēnei hua?
(1) Prohexadione calcium: He momo hou tēnei o te aukati i te tipu o ngā tipu.
Ko te mahi he ārai i te GA1 i roto i te gibberellin, he whakapoto i te roa o te kakau o ngā tipu, ā, he whakahaere hoki i te tipu o ngā tipu. I taua wā anō, kāore he pānga ki te GA4 e whakahaere ana i te rerekētanga o te puku pua me te whanaketanga o te witi.
I whakarewaina te konupūmā Prohexadione ki Hapani i te tau 1994 hei ārai tipu acyl cyclohexanedione. He rerekē te kitenga o te konupūmā prohexadione i tērā o ngā tote ammonium quaternary (chameleon, mepinium), nā ngā triazole (paclobutrazol, alkene) kua hangaia he mara hou mō te aukati i te biosynthesis gibberellin i te wā mutunga, ā, kua hokohokohia, kua whakamahia whānuitia hoki i Ūropi me te Hononga o Amerika. I tēnei wā, he nui te aro o ngā umanga ā-rohe ki te prohexadione-calcium, ko te take matua he whakataurite ki ngā ārai triazole, kāore he paitini toenga o te prohexadione-calcium ki ngā tipu hurihuri, kāore he poke ki te taiao, ā, he painga nui tōna. I te heke mai, ka taea e ia te whakakapi i ngā ārai tipu triazole, ā, he whānui ngā tono ki ngā mara, ngā rākau hua, ngā putiputi, ngā rauemi rongoā Hainamana me ngā hua ōhanga.
(2) Paclobutrazol: He aukati i te waikawa gibberellic taketake o te tipu. He pānga tōna ki te whakaroa i te tipu o te tipu, te aukati i te roa o te kakau o te hua, te whakapoto i ngā peka, te whakatairanga i te tilling, te whakanui ake i te ātete ki te ahotea o te tipu, te whakatairanga i te whakaputa uri o te puku putiputi me te whakanui ake i te hua. He pai te Paclobutrazol mō ngā hua pēnei i te raihi, te witi, te pīnati, ngā rākau hua, te pīni soya, te tarutaru, me ētahi atu, ā, he pānga whakamiharo tōna ki te whakahaere i te tipu.
Ngā pānga taha o te paclobutrazol: Ki te nui rawa te whakamahinga ka pāngia ngā tipu e te iti, ka pirau ngā pakiaka me ngā kōpura, ka piko ngā rau, ka koretake ngā putiputi, ka marere wawe ngā rau tawhito i te pūtake, ka piko, ka mimiti hoki ngā rau taitamariki. Nā te roa o te whai huatanga o te paclobutrazol, ka noho tonu te whakamahinga nui ki te oneone, ā, ka pāngia hoki te hua e whai ake nei e te paitini tipu, ka kore ai he tipu hou, ka tōmuri te putanga mai, ka iti te tere o te putanga mai o te tipu hou, ka pirau te tipu hou me ētahi atu tohu paitini tipu.
(3) Uniconazole: He aukati hoki i te gibberellin. Ko āna mahi he whakahaere i te tipu tipu, he whakapoto i ngā internodes, he whakaiti i ngā tipu, he whakatairanga i te tipu o te puku taha me te rerekētanga o te puku putiputi, me te whakarei ake i te ātete ki te ahotea. Nā te here takirua waro o te paclobutrazol, ko tōna mahi koiora me tōna pānga rongoā he 6 ki te 10 ngā wā me te 4 ki te 10 ngā wā teitei ake i te paclobutrazol, ia, ā, ko te nui o te toenga i roto i te oneone he tata ki te hauwhā o te paclobutrazol, ā, ko tōna whai huatanga he tere ake te tere pirau, ā, ko te pānga ki ngā hua o muri mai he 1/5 noa iho o te paclobutrazol.
Ngā pānga taha o te uniconazole: ina whakamahia i roto i te nui rawa o te horopeta, ka pāngia ngā tipu e te paitini, ka wera ngā tipu, ka memeha, ka ngoikore te tipu, ka hē te ahua o ngā rau, ka hinga ngā rau, ka hinga ngā putiputi, ka hinga ngā hua, ka tōmuri te pakari, me ētahi atu, ā, ko te whakamahinga i te wā whakatipu huawhenua ka pā ki te tipu o ngā tipu. He paitini hoki ki ngā ika, ā, kāore e pai mō te whakamahi i roto i ngā roto ika me ētahi atu pāmu kararehe wai.
(4) Peptidamine (Mepinium): He aukati i te gibberellin. Ka taea e ia te whakarei ake i te hanganga o te chlorophyll, he pakari te tipu, ka taea te mimiti mā roto i ngā rau me ngā pakiaka o te tipu, ka tukuna ki te tipu katoa, ka aukati i te roa o te pūtau me te mana o runga, ā, ka taea hoki te whakapoto i ngā internodes me te hanga i te momo tipu kia kikī. Ka taea e ia te whakaroa i te tipu tipu o te tipu, te aukati i te tipu kia kore e tupu, me te whakaroa i te hiri. Ka taea e te Peptamine te whakapai ake i te pumau o ngā kiriuhi pūtau me te whakanui ake i te ātete ki te ahotea o te tipu. Ki te whakatauritea ki te paclobutrazol me te uniconazole, he ngawari ake ngā āhuatanga rongoā, kāore he riri, ā, he haumaru ake. Ka taea te whakamahi i roto i ngā wā katoa o ngā hua, tae atu ki ngā wāhanga tipu me te pua i te wā e tino pāngia ana ngā hua e ngā rongoā, ā, kāore he pānga kino.
(5) Chlormetrodin: Ka tutuki te pānga o te whakahaere i te mahi nui mā te aukati i te hanga o te gibberellin taketake. He pānga whakahaere a Chlormetrodin ki te tipu o te tipu, ka whakataurite i te tipu tipu me te tipu uri, ka whakapai ake i te tere o te whakapūpū me te whakatakoto hua, ā, ka whakanui ake i te whai hua o te tire. Ka whakaroa i te roa o te pūtau, ka whakawhāiti i ngā tipu, ka pakari ngā kakau, ā, ka whakapoto i ngā internodes.
He rerekē i te paclobutrazol me te mepiperonium, he maha ngā wā e whakamahia ana te paclobutrazol i te wāhanga tipu me te wāhanga wana hou, ā, he pai te pānga ki ngā pīnati, engari he whānui te pānga ki ngā hua o te ngahuru me te hotoke; mō ngā hua poto, ko te whakamahinga hē o te chlormethaline ka whakaiti i te hua, ā, he uaua ki te whakamamae i te paitini tipu; he ngawari te mepiperinium, ā, ka taea te whakamamae mā te rehu i te gibberellin, te whakamakuku rānei hei whakanui ake i te momona i muri i te paitini tipu.
