He Whakatakotoranga Tipu Whakaoho Pūtake Whai Hua e Hoko Ana i te Wheketere mō ngā Rākau

He rongoā a Paclobutrazol (PBZ)Kaiwhakahaere Tipu TipumePatu patu harore.He hoariri rongonui tēnei o te homoni tipu gibberellin.Ka aukati i te hanga o te gibberellin, ka whakaiti i te tipu o ngā wana waenga kia pakari ake ai ngā kakau, ka whakanui ake i te tupu o ngā pakiaka, ka hua wawe ai ngā hua, ā, ka nui ake te putanga mai o ngā purapura i roto i ngā tipu pērā i te tōmato me te pepa. E whakamahia ana te PBZ e ngā tohunga rākau hei whakaiti i te tipu o ngā wana, ā, kua whakaatuhia he pānga pai anō ki ngā rākau me ngā rakau iti.Kei roto i ēnei ko te ātete pai ake ki te ahotea tauraki, te rau matomato pouri ake, te ātete nui ake ki te harore me te huakita, me te whanaketanga pai ake o ngā pakiaka.Kua kitea te hekenga o te tipu cambial, me te tipu wana, i roto i ētahi momo rākau. Kāore he paitini ki ngā kararehe whakangote.

Whakamahinga

1. Te whakatipu tipu kaha i roto i te raihi: Ko te wā rongoā pai mō te raihi ko te wā kotahi rau, kotahi te wā ngākau, arā, 5-7 ngā rā i muri i te rui. Ko te horopeta tika mō te whakamahi ko te 15% paura paclobutrazol mākū, me te tāpiri i te 3 kirokaramu mō ia heketea me te 1500 kirokaramu wai.

Te ārai i te noho o te raihi: I te wā e whakatō ana i te raihi (30 ngā rā i mua i te kotinga), whakamahia te 1.8 kirokaramu o te paura mākū 15% paclobutrazol mō ia heketea me te 900 kirokaramu wai.

2. Whakatipuhia ngā tipu rēpī kaha i te wā e toru ngā rau, mā te whakamahi i te 600-1200 karamu o te paura mākū 15% paclobutrazol mō ia heketea me te 900 kirokaramu wai.

3. Hei ārai i te tipu nui o te pīni soya i te wā pua tuatahi, whakamahia he 600-1200 karamu o te paura makuku 15% paclobutrazol mō ia heketea, ā, tāpirihia he 900 kirokaramu wai.

4. Mā te whakahaere i te tipu o te witi me te whakakakahu i ngā purapura me te hohonutanga e tika ana o te paclobutrazol ka kaha ake te tipu o te tipu, ka nui ake te tiu, ka iti ake te teitei, ā, ka nui ake te hua o te witi.

Ngā Aro

1. He kaha te aukati tipu o te Paclobutrazol, ā, ko te haurua-ora i roto i te oneone i raro i ngā āhuatanga noa he 0.5-1.0 tau, ā, he roa te wā pānga toenga. I muri i te rehu ki te mara, ki te wāhanga tipu huawhenua rānei, he maha ngā wā ka pā ki te tipu o ngā hua o muri mai.

2. Kia tino aro turuki i te horopeta o te rongoā. Ahakoa he nui ake te kukū o te rongoā, he kaha ake te pānga o te whakahaere roa, engari ka heke iho anō te tipu. Mena ka puhoi te tipu i muri i te whakahaere nui rawa, ā, kāore e taea te whakatutuki i te pānga o te whakahaere roa i te horopeta iti, me pania kia ōrite te nui o te rehu e tika ana.

3. Ka heke te roa me te ngau o te tipu i te pikinga ake o te nui o te rui, ā, kāore te nui o te rui o te raihi mutunga ranu e neke ake i te 450 kirokaramu/heketea. Ko te whakamahi i ngā ngau hei whakakapi i ngā tipu ka ahu mai i te rui iti. Āraia te waipuke me te whakamahi nui rawa o te tongi hauota i muri i te tono.

4. He pānga ārai-aukati te pānga whakatairanga tipu o te paclobutrazol, te gibberellin, me te waikawa indoleacetic. Mēnā he nui rawa te horopeta, ā, he nui rawa te aukati i ngā tipu, ka taea te tāpiri i te tongi hauota, te gibberellin rānei hei whakaora i a rātou.

5. He rerekē te pānga whakaitiiti o te paclobutrazol ki ngā momo raihi me te witi rerekē. Ina whakamahia, me whakanui, me whakaiti rānei i te horopeta kia tika, ā, kaua e whakamahia te tikanga rongoā oneone.
