Ko te pakeketanga o te matūriki tētahi o ngā tohu kounga e aro nui ana ngā kamupene whāngai katoa. I roto i ngā whāngai kararehe me ngā heihei, ka kore e reka te kai i roto i te kai, ka whakaiti i te kai e kainga ana, ā, ka puta hoki he mate pukupuku waha i roto i ngā poaka ngote. Heoi, ki te iti te pakeketanga, ka heke te nui o te paura. Ko te pikinga ake, inā koa te iti o te pakeketanga o ngā rauemi pirepire, ka puta hoki he āhuatanga kounga kino pēnei i te whakarōpūtanga whāngai. Nō reira, me whakarite e ngā umanga kia tutuki te pakeketanga o te whāngai i ngā paerewa kounga. Haunga te whakarerekē i te tātai whāngai, ka arotahi hoki rātou ki ngā wāhanga rerekē o te tukanga whakaputa me te tukatuka, ka pā nui hoki ki te pakeketanga o te whāngai pirepire.
1) Ko te mea nui e pā ana ki te pakeketanga o ngā matūriki i roto i te tukanga huri ko te rahi o ngā matūriki huri o ngā rauemi mata. I te nuinga o te wā, ko te iti ake o te rahi o ngā matūriki huri o ngā rauemi mata, ka māmā ake te whakakorikori o te māngaro i te wā o te tukanga whakatikatika, ā, ka kaha ake te pānga piri o ngā pirepire. Ko te kore e ngawari te pakaru, ka nui ake te pakeke. Nō reira, i roto i te mahi whakaputa tuturu, me whakarite tika te rahi o te matūriki kuru kia rite ki te mahi whakaputa o ngā kararehe rerekē me te rahi o te whakatuwheratanga mowhiti.
2) Mā te tukatuka pupuhi o ngā rauemi mata, ka taea te tango i ngā paitini i roto i ngā rauemi mata, ka taea te whakamate i ngā huakita, ka taea te whakakore i ngā matū kino, ka taea te whakakore i ngā pūmua i roto i ngā rauemi mata, ā, ka taea te whakakorikori katoa i te māngaro. I tēnei wā, ko ngā rauemi mata pupuhi te nuinga o te wā e whakamahia ana mō te hanga kai poaka ngote kounga teitei me ngā kai wai motuhake. Mō ngā hua wai motuhake, i muri i te pupuhi o ngā rauemi mata, ka piki ake te kaha o te whakakorikori māngaro, ā, ka piki ake hoki te pakeke o ngā matūriki kua hangaia, he mea pai tēnei mō te whakapai ake i te pumau o ngā matūriki i roto i te wai. Mō te kai poaka ngote, me pakari ngā matūriki, kaua e tino mārō, he mea pai tēnei mō te whāngai poaka ngote. Heoi, nā te nui o te whakakorikori māngaro i roto i ngā pire poaka ngote pupuhi, he nui hoki te pakeke o ngā pire kai.
3) Mā te whakaranu i ngā rauemi mata ka taea te whakapai ake i te ōritetanga o ngā wāhanga rahi matūriki, he mea pai tēnei hei pupuri i te pakeketanga o te matūriki kia ōrite tonu, hei whakapai ake hoki i te kounga o te hua. I roto i te hanga whāngai pire mārō, mā te tāpiri i te 1% ki te 2% makuku ki roto i te mīhini whakaranu ka āwhina i te whakapai ake i te pumau me te pakeketanga o te whāngai pire. Heoi, me whakaaro anō hoki ki ngā pānga kino o te pikinga o te makuku ki te whakamaroke me te whakamatao o ngā pire. Kāore hoki e pai mō te rokiroki hua. I roto i te hanga whāngai pire mākū, ka taea te tāpiri i te 20% ki te 30% makuku ki te paura. He māmā ake te tāpiri i te 10% makuku i te wā e whakaranua ana i te wā e whakatikatika ana. He iti te pakeke, te ngawari, me te reka pai o ngā pire i hangaia mai i ngā rauemi makuku nui. Ka taea e ngā umanga whakatipu nui te whakamahi i tēnei whāngai pire mākū. Ko ngā pire mākū he mea uaua ki te penapena i te nuinga o te wā, ā, me whāngai tonu i muri i te hanga. Ko te tāpiri hinu i te wā e whakaranua ana he tukanga tāpiri hinu e whakamahia whānuitia ana i roto i ngā awheawhe hanga whāngai. He iti noa te pānga o te tāpiri i te 1% ki te 2% o te hinu ki te whakaiti i te pakeke o ngā matūriki, engari ka taea e te tāpiri i te 3% ki te 4% o te hinu te whakaiti nui i te pakeke o ngā matūriki.
4) He tukanga matua te whakamahana i te mamaoa i roto i te tukatuka whāngai pire, ā, ka pā tika te pānga whakamahana ki te hanganga ā-roto me te kounga o te āhua o ngā pire. Ko te kounga o te mamaoa me te wā whakamahana he mea nui e rua e pā ana ki te pānga whakamahana. Ka taea e te mamaoa maroke me te mamaoa kua mākū te whakarato i te wera nui ake hei whakanui ake i te pāmahana o te rauemi me te whakakorikori i te māngaro. Ka roa ake te wā whakamahana, ka teitei ake te taumata o te whakakorikori māngaro. Ka teitei ake te uara, ka matotoru ake te hanganga matūriki i muri i te hanganga, ka pai ake te pumau, ā, ka nui ake te pakeke. Mō te whāngai ika, ka whakamahia ngā koti paparua, paparua rānei mō te whakamahana hei whakanui ake i te pāmahana whakamahana me te whakaroa i te wā whakamahana. He pai ake te whakapai ake i te pumau o ngā matūriki whāngai ika i roto i te wai, ā, ka piki ake hoki te pakeke o ngā matūriki.
5) I te wā o te tukanga whakapūkara, ka pāngia hoki te pakeke o ngā matūriki e ngā tawhā hangarau pēnei i te pūaha me te ōwehenga kōpeketanga o te mate mowhiti. Ka tino piki ake te pakeke o ngā matūriki i hangaia e ngā pokepokea mowhiti me te pūaha kotahi engari he rerekē ngā ōwehenga kōpeketanga me te pikinga o te ōwehenga kōpeketanga. Mā te whiriwhiri i tētahi mate mowhiti me te ōwehenga kōpeketanga tika ka taea te whakaputa i ngā matūriki me te pakeke tika. I taua wā anō, he pānga nui anō hoki te roa o ngā matūriki ki te kaha kawe pēhanga o ngā matūriki. Mō ngā matūriki o te diameter kotahi, ki te kore he hapa o ngā matūriki, ka roa ake te roa o te matūriki, ka nui ake te pakeke i inehia. Nō reira, mā te whakarerekē i te tūranga o te kaitapahi kia mau tonu te roa o te matūriki ka taea te pupuri i te pakeke o ngā matūriki kia rite tonu. He pānga anō hoki te diameter o te matūriki me te āhua whakawhiti-wāhanga ki te pakeke o ngā matūriki. Hei tāpiri, he pānga anō hoki te rauemi o te mate mowhiti ki te kounga āhua me te pakeke o ngā pirepire. He rerekētanga mārama i waenga i te whāngai pirepire i hangaia e ngā mate mowhiti maitai noa me ngā mate mowhiti maitai kore waikura.
Hei whakaroa i te wā rokiroki o ngā hua whāngai me te whakarite i te kounga o te hua i roto i tētahi wā kua whakaritea, me whakamaroke me te whakamatao i ngā matūriki whāngai e tika ana.
