Manaʻo kūpono ka hapanui i ka maopopoʻana o kaʻokoʻa ma waena o kekahi kumu lāʻau a me kahi ulu lāʻau, akā e hiki iāʻoe ke wehewehe? Heʻuʻuku ke kumu lāʻau ma mua o ka lāʻau,ʻae. Akā,ʻoi aʻe. ʻO ka mea haku inoaʻo Pelekāniaʻo David Domoney e'ōlelo nei no nāʻokoʻa ma waena o nā kumu lāʻau a me nā kumu lāʻau:
"Ua weheweheʻia ka ulu lāʻau e like me ka mea kanu ulu iʻoi aku ka liʻiliʻi ma mua o ka lāʻau aʻo keʻano heʻano kepoe.ʻO ka mea nui ma waena o nā meaʻelua, he nui nāʻano kumu nui e ulu mai ana mai ka papa honua, ma mua aʻe o ka pahu hoʻokahi ...ʻO ka hua'ōlelo 'ʻuʻuku iho i ka lāʻau' hiki ke alakaʻi hewa, akā.ʻO kaʻoiaʻiʻo, hiki ke loli ke kumu i nā mea nui mai ka uhi honua a hiki i nā mea nui. "
Pono ka hopena e like lākou me ka likeʻole aʻaʻole like. E nānā i nā hiʻohiʻona o kēlā me kēia me nā kiko kiko'ī.
Nāʻano o nā lāʻau
ʻO ka mea mua, nā lāʻau, nā lāʻau liʻiliʻi, a me nā kumu waina i hoʻohuiʻia nā mea kanu wale nō me ka uluʻana o ka ulu, e like me keʻano likeʻole. Nui nā poʻe e noʻonoʻo,ʻo ka mea i kapaʻia he'ulahi he lāʻau, akā,ʻo ka mea maoli, ua manaʻoʻia lākou he ulu lāʻau nui loa o ka honua.
Keʻike wikiwikiʻoe i ka uluʻana o ka ulu, hiki iāʻoe keʻike i ka lāʻau, kahi lāʻau ulu, aiʻole he kumu waina. Heʻike nā māla no ko lākou mau mea lahilahi a me nā lālā a me ko lākou ulu ulu. Akā,ʻoi aku ka paʻakikī o kaʻokoʻa ma waena o nā kumu lāʻau a me nā kumu. ʻO ka hoʻohālikelikeʻana i keʻano o ka lāʻau, e like me ka'Āinaʻo Utah State (USU), he "kumu lāʻau i kanuʻia hoʻokahi pahu kūikawā ma lalo oʻekolu iniha ke anawaena ma ka helu 4 1/2 kapuaʻi ma luna o ka lepo, ua hanaʻia i ka lei aliʻi, a he kiʻekiʻe loa o kahi he 13 kapuaʻi. "
Uaʻaeʻo Merriam-Webster, e wehewehe ana i kahi lāʻau e like me: "he lāʻau ulu ulu e like me ka mea maʻamau i keʻano o nā mea nui a me nā lālāʻole ma konaʻaoʻao lalo."
Ke wehewehe nei ka weheweheʻana i nā lāʻau i ka nānāʻana i kā lākou physiology:
- ʻO kahi lāʻau, he ulu nui me kaʻili manu. Hiki i nā lālā ke hōʻiliʻili i ka mālamalama no ke kiʻiʻana ma o lākou mau lau; hana kēia hana i "meaʻai" no ka lāʻau.
- ʻO ka hapanui o kahi kumu lāʻau he kino make a lawelawe wale i ke kākoʻo i ke kaumaha o ka lei aliʻi. ʻO nāʻaoʻao o waho o ke kumu lāʻauʻo ia wale nō ka mea ola. Hoʻokumu ka cambium i ka lāʻau hou a me ka'ō'ō hou.
- ʻO ka pēpē lole ma waho o ka cambium ka phloem. Huakaʻiʻo Phloem i nā mea hou (nā suga i hanaʻia mai photosynthesis) mai ka lei aliʻi a hiki i ke aʻa. ʻO kaʻili o ka phloem ka make makeʻo ka lāʻau.
- ʻO ka pēpiliʻokoʻa wale nō i loko o ka cambium ka xylem , ka mea e lawe i ka wai mai ke aʻa a hiki i ka lei. ʻO nā mea make a me nā mea make e hana i nā lāʻau ulu, aiʻole ka lāʻau i hoʻohanaʻia no nā kumu likeʻole.
- I kēlā me kēia makahiki, ulu nā lāʻau iʻelua mau milika lima. I ka pūnāwai, he papa pālahalaha nui a lahilahi i kapaʻia he ulu lāʻau. I ke kauwela, kahi pālahalaha nui paʻa i ka pā, i kapaʻia he lāʻau ulu. ʻO nā'ōpili āpau keʻano i ka nahele ulu.
ʻO nā lāʻau kūikawā i loaʻa maʻAmelika Huipūʻia, ua komo pū me: ke kumulāʻauʻulaʻula, ka paina pinepine, ka momona, ke kumukū Douglas, ka haʻalulu aspen, ke kumine kele, ka pua balsam, ka wili pua, ka pine pingepole, a me kaʻoloʻeleʻele.
Nāʻano o nā kumu lāʻau
Ua weheweheʻia nā kumulāʻau e like me: "kahi mea kanu ulu me kekahi mau momonaʻoihana e hiki ke hoʻokumu a kokoke paha i ka honua.
Hāʻawiʻo Merriam-Webster i kahi lāʻau ulu "he mea kanu liʻiliʻi,ʻo ia hoʻi heʻano ulu lāʻau ulu," a me "kahi kumu ulu ulu nui iʻoi aku ka liʻiliʻi ma mua o ka nui o nā lāʻau."
Inā pahaʻoe e kapa iā lākou he mau kumu lāʻau a lāʻau ulu paha, he "waiwai nui kēia mau mea kanu i kekahi'āina," wahi a Jerry Goodspeed, USU Hoʻoponopono Hōkū:
"ʻO nā kumulāʻauʻo ia nā mea kanu e kūkākūkā nei kākou - kōkua lākou iā mākou eʻike i kahi o ka'āina no ka mea ua laweʻia mai i lalo i ko mākou kiʻekiʻe. ʻO kahi kumu lāʻau a me ka nāhelehele he kumu ulu ulu me kahi kiʻekiʻe o ke kiʻekiʻe ma waena o hoʻokahi a me ka hapalua a me ka 10 kapuaʻi aʻoi aku ka mea liʻiliʻi i ka lepo.
E hoʻomaopopo he mau manaʻo likeʻole e pili ana i ka kiʻekiʻe o nā kumu liʻiliʻi.
Paiʻo Goodspeed i ka kiʻekiʻe kiʻekiʻe o kahi ulu lāʻau i 10 mau kapuaʻi, aʻo nā mea'ē aʻe, e like me kā mākou i hōʻike ai ma luna nei, e hoʻolālā i 13 kapuaʻi. I kekahi hihia,ʻoi aku ka nui o nā kiʻekiʻeʻelua ma mua o nā lāʻau kiʻekiʻe.
ʻO nā kumu kūikawā i loaʻa maʻAmelika Huipūʻia,ʻo ia nō: nā'īlio kilokilo, nā kānana, nā lilacs, ke rose o Sharon, Fothergilla,ʻo oakleaf hydrangea, ka ululāʻauʻulaʻula ulaʻula, ke kumukū, ka King Gold a me Gold Mops, Stewartstonian azalea, Roses, a me hibiscus.
Nā HōʻikeʻAna
ʻO kēia mau ho'ākāka e lilo i mau kumu hoʻomaka maikaʻi no kaʻikeʻana i waena o nā kumu lāʻau a me nā lāʻau liʻiliʻi, akā, e like me nā mea he nui, he mau hoʻokoe. ʻOiai e hahai anaʻoe i nā manaʻo nui, akā, e hiki iāʻoe ke hoʻoholo inā he lāʻau ka lāʻau ulu.
Hiki i kekahi mau lāʻau, e like me ka hoʻonani muliwai a me ka māpani Iapana paha, he mau kolamu nui. Hiki ke hoʻohālikeʻia kekahi mau lāʻau i loko o kahi kumulāʻau ma o ke aʻoʻana i kahi pahu.
ʻO nā mea kanu likeʻole e like me nā kūmole, nā kānake, he mau mea kanu ia e hiki ke ulu e like me kahi lāʻau ulu lāʻau. Inā haʻalele wale iā lākou, hiki iā lākou ke lilo i "pōpō," e like me Dennis Hinkamp o ka USU Extension. Hōʻikeʻo ia:
"He kumulāʻau kahi hikiʻole ke hoʻoholo inā he kumu lāʻau paha kahi lāʻau, ua uluʻo ia, akā ua ulu i kahi kiʻekiʻe o ka 15 kapuaʻi, aʻo ia ka mea i hoʻohālike iā ia heʻoiaʻiʻo maoli .... Jerry Goodspeed, moku'āinaʻo'Imelika Hoʻokumuʻia ka uluʻana o nā'Āleʻele ... no ka mea, uaʻoi aʻe ka hua o ka lāʻau a me ka ulu lāʻau. I ka wā i aʻoʻia ai e like me ka lāʻau, hiki i nā lālā ke ulu i kahi 20 kapuaʻi ke kiʻekiʻe, me ka palahalaha likeʻole, e'ōlelo ana [Goodspeed] No ka mea, makemake lākou i ka pollination, no laila e pono ke kanuʻia nāʻanoʻelua.
