Kunenani elikhulu lezihlahla ezibonakala kakhulu emhlabeni wonke ngenxa yokuhlukahluka kwezinhlobo zezilwane, kulokhu kufanele kugqanyiswe i-Douglas Fir, engenye edume kakhulu ngokuba ngesinye sezihlahla ezinde kakhulu emhlabeni nokuba nobukhulu obukhulu. , masifunde kabanzi ngalolu hlobo lwezilwane ezinhle kakhulu.
I-Fir
I-fir ihambisana nesihlahla somndeni wakwaPinaceae noma we-Abietaceae, iphinde ithathwe njengohlobo lwe-Abies olungaholela enanini elikhulu lezinhlobo lapho zibonakala ngokuba nobude obukhulu obufinyelela kumamitha angama-50. ngisho nezinhlobo ezinamamitha angama-80, iziqu zazo zivame ukuba mhlophe, ziqonde kakhulu futhi umqhele wazo u-conical, ungaba nesimo se-cylindrical.
Ngokujwayelekile izihlahla zefir zivame ukukhula endaweni ephakeme kakhulu lapho isimo sezulu kubanda kakhulu khona, sitholakala emahlathini aseNyakatho Melika, e-Asia naseYurophu; bangadideka nemisedari. Ukhuni lwayo lufunwa kakhulu ukuze lwakhiwe futhi ngenxa yombala nobukhulu bayo luba yigugu kakhulu ukuba yingxenye yamafreyimu neminyango, efunwa kakhulu ngezindawo zayo ezingavamile ezinokuqina okukhulu.
Douglas Fir
Izihlahla zefir zenziwe ngezinhlobonhlobo ezinkulu kuleli cala, i-Douglas Fir ingagqanyiswa. Ama-firs ngokuvamile ayizinhlobo ezincane, eziphakathi, noma eziphakeme kakhulu ze-coniferous, i-Douglas-fir ingeyeqembu lokugcina. Lapho inobude obuphakathi kwamamitha angama-60 kuya ku-75, ithathwa njengendawo yesithathu ephakeme kunazo zonke emhlabeni, okokuqala ngqa. I-Sequoia sempervirens (redwood) kanti endaweni yesibili i- I-Sequoiadendron giganteum (i-giant sequoia).
I-Douglas Fir yaziwa nangokuthi i-Oregon Pine, i-British Columbia Pine, phakathi kwamanye amagama amaningi kodwa edume kakhulu ngokwaziwa ngokuthi i-giant phakathi kwama-giants, inikezwa njengengxenye yesihlanu yazo zonke iziqiwi ze-coniferous, kuba Ungasho ukuthi kukhona ziyizinhlobo ezifika kumamitha angu-126 ukuphakama namamitha angu-5,5 ububanzi.
Umsuka kanye Nezimpawu
Kubhekwa njenge-conifer eyaziwa ngokuthi iGreen Douglasia, i-Rocky Green False Tsuga, i-Oregon Pine, i-Oregon Douglas, noma i-Douglas Fir, phakathi kwamanye amagama amaningi. Itholakala eNyakatho Melika, ikakhulukazi eningizimu-ntshonalanga yeCanada kuya ezindaweni zaseCalifornia e-United States. Ziyizinhlobo ezivame kakhulu zokufinyelela kumamitha angu-75 ukuphakama, ama-specimens anobubanzi besiqu esingamamitha angu-4,5 kuya ku-6 angatholakala.
Ukukhula kwazo kuhamba kancane, ziphila isikhathi eside lapho zikwazi ukufinyelela eminyakeni engu-500 ubudala futhi kukhona ngisho nezinhlobo ezineminyaka eyi-1000 ubudala. I-Douglas fir ibonakala ngokuba nesiqu esiqondile, amagxolo ayo abushelelezi futhi ampunga uma esemncane futhi anemifantu ngokuhamba kwesikhathi futhi njengomuntu omdala.
Wonke amaqabunga anomumo ozungezayo, kwesinye isikhathi angasonteka esisekelweni futhi afane nenaliti, afinyelele ku-5 kuya ku-11 amasentimitha ubude kuya ku-2 kuya ku-3,5 amasentimitha ububanzi. Angakhuhlwa futhi akhiphe iphunga elifana nelezithelo ezifana nelamula noma i-tangerine. Izigaxa zayo ziyi-peduncular ekwazi ukukwazi ukuba nembali, iqabunga nesithelo, zingakala phakathi kwamasentimitha angu-5 kuya ku-11 ubude kanye namasentimitha angu-2 kuya kwangu-3 ububanzi; amaqabunga awo avamise ukuba nsundu kanye nowolintshi ngemva kokufinyelela ekuvuthweni. Imbewu ikala u-5-6 mm ubude no-3-4 mm ububanzi, futhi ibe nophiko oluyi-12-15 mm.
Izinhlobo ezingaphansi
I-Douglas Fir ithathwa njengesihlahla sobuhle obukhulu esatshalaliswa ikakhulukazi ogwini lwasePacific e-United States nasemapaki aseCentral Europe, imvamisa itholakala enhlabathini enesihlabathi nesijulile, ingaba ne-asidi elinganiselwe futhi isha, lapho. kunezinhlobo ezimbili ze-subspecies:
- I-Pseudotsuga menziesii var. menziesii: Abonakala ngokukhula ezindaweni ezisogwini ukusuka entshonalanga namaphakathi neNyakatho Melika. Njengoba isakazeke kakhulu endaweni esezingeni lolwandle, iwuhlobo oluphakathi kwamamitha angama-75 ukuphakama nobukhulu obungu-2 ububanzi.
- I-Pseudotsuga menziesii var. I-Glauca: Eyaziwa nangokuthi i-Mountain Douglasia, uhlobo olubonakala kakhulu phakathi kwe-Rocky Mountains. Iyakwazi ukufinyelela kumamitha angu-45 ukuphakama, ingatholakala ezindaweni zaseMexico, Querétaro, Puebla naseTiaxcala.
Ukusetshenziswa kwe-Douglas Fir
Ihambisana ne-conifer edume kakhulu embonini nakwezomnotho okufanele isetshenziselwe futhi isetshenziselwe ukhuni olufanelekile olunelisa izidingo eziyinhloko zokufeza ukusebenza, imboni iphethe imikhiqizo eningilizayo ngesakhiwo futhi futhi engeyona. -indlela yesakhiwo, ukubamba iqhaza ekubazeni, ukwakhiwa kwamashede, ama-pergolas noma ifenisha yangaphandle, kanye nokubamba iqhaza ekukhiqizeni iphepha.
Ibuye isetshenziswe njengesitshalo sokuhlobisa ukuhlobisa izindawo zangaphandle ezifana nezingadi, inokutshalwa kabusha kwamahlathi asetshenziswa ezindaweni ezihlukahlukene emhlabeni wonke ukuze kwandiswe izinhlobo zezilwane ezindaweni ezihlukahlukene zamazwekazi. Kulokhu, iSpain igqamile, lapho i-Douglas Fir itshalwe khona kusukela ngonyaka we-90, ikakhulukazi enyakatho ye-peninsula ngenxa yokuthi isimo sezulu sihle kakhulu.
I-Douglas Fir Care
I-Douglas fir isihlahla esikhulu futhi esikhulu esinamagxolo aminyene kakhulu, amakhokho futhi aqhekekile, umqhele wawo awujwayelekile futhi unamagatsha alenga anombala oluhlaza okotshani, agqama kakhulu ngokhuni lwawo, phakathi kwezincomo zokongiwa kwalolu hlobo. okulandelayo kuyagqama:
- Indawo: Ngenxa yobukhulu bayo obukhulu kunconywa ukuthi ibe ngaphandle, ibekwe elangeni, uma kwenzeka ukukhanya kwelanga okunamandla kunconywa ukuba ibe semithunzi. Ngakho-ke, kufanele itshalwe ebangeni eliphakathi kwamamitha angu-6 kuya kwangu-7 ukusuka ezindongeni, amapayipi, phakathi kwabanye.
- Umhlaba: I-substrate esetshenziswayo kufanele ibe ne-acidic kancane kanye nenhlabathi evundile, okungcono kunothe ngezinto eziphilayo.
- Ukunisela: Kunconywa ukuthi usebenzise amanzi izikhathi ezi-3 noma ezine ngesonto ngesikhathi sasehlobo.
- Obhalisile: umanyolo kufanele usetshenziswe entwasahlobo nasehlobo, okungcono umanyolo we-organic.
- Ukuphindaphinda: ukuzala kwawo kufanele kube ngembewu ngesikhathi sasebusika, amakhaza ayadingeka ngaphambi kokuba aqhume.
- Ukuqina: I-Douglas fir iyakwazi ukumelana nokufika ku -18ºC, kodwa ayikwazi ukumelana nalezo zimo zezulu ezishisayo noma ezishisayo. Ngakho-ke, kunconywa ukuthi ulinywe ezindaweni ezisezintabeni.
Sithemba ukuthi le ndatshana ibe wusizo, sikushiyela abanye ozokuthakasela ngokuqinisekile:
isihlahla sesundu sasebukhosini
