Kune madiki conifers, mamwe epakati, mamwe makuru uye mamwe anoremedza. Iyo Douglas fir ndezveboka rekupedzisira. Nechekukwirira kuri pakati pemakumi matanhatu nemakumi manomwe nemashanu emamita, ndiyo yechitatu pakureba kwazvo pasirese, iri kumashure kweiyo sequoia sempervirens (redwood) uye Sequoiadendron giganteum (hofori sequoia).
Iine hunhu ihwohwo, vashoma kwazvo vangatarise kuve nahwo mubindu, handiti? Uye hazvisi zvishoma, nekuti dhayamita ye trunk haina kusiya hanya: kubva 1,5 kusvika 2 metres. Kunyangwe zvakadaro, kuve unopokana kwazvo nechando uye kuve nekukurumidza kukura, iri mhando inonakidza kwazvo yenzvimbo dzakapamhama.
Mavambo uye hunhu
Iyo conifer inozivikanwa seGreen Douglasia, Rocky Nhema Green Hemlock, Oregon Pine, Oregon Douglas, kana Douglas Fir yemuno kuNorth America, kubva kumaodzanyemba kwakadziva kumadokero kweCanada kusvika pakati peCalifornia muUnited States. Sezvatakataura, inogona kusvika kureba kwemamita makumi manomwe nemashanu, kunyange zvakadaro zvienzaniso zve 100-120 metres zvakawanikwa ine trunk dhayamita ye4,5 kusvika 6m.
Kukura kwaro kunononoka, asi tarisiro yeupenyu hwakareba kwazvo; zvirinani kuti inogona kusvika makore mazana mashanu, uye dzimwe nguva inodarika chiuru. Inozivikanwa nekuve nehunde yakatwasuka, ine bark nyoro uye grey uchiri mudiki. .
Mashizha acho akarongedzwa achitenderera, akati akamonyoroka pazasi, uye akaita senge tsono, dzakareba kusvika pamasendimita gumi nemasere pakureba ne 5-11cm yakafara. Kana dzikakwizwa, dzinopa hwema hunoyeuchidza michero. Makoni ari peduncular, mashanu kusvika 2cm kureba ne 3,5-5cm yakafara, uye ane brownish-orenji kana akura. Mbeu idzi dzakareba 11-2mm ne 3-5mm yakafara, uye dzine 6-3mm bapiro.

Use
Ichi chi conifer chakashandiswa uye chinoshandiswa zvakanyanya kuhuni dzacho, icho chinoshandiswa mukuveza uye pakuvaka matumba, pergolas, uye fenicha yekunze, pamwe nekugadzira mapepa.
Asi zvakare Iyo yakanaka kwazvo yekushongedza chirimwa, uye yekudyara masango. MuSpain yakasimwa kubva kuma1990 kuchamhembe kwepeninsula, kunova ndiko kune mamiriro ekunze akanaka.
Ndezvipi zvinovanetsa?
Kana iwe uchida kuve neiyo Douglas fir specimen, tinokurudzira kuzvipa zvinotevera kutarisira:
- Nzvimbo: inofanira kunge iri kunze, muzuva rose kana, kana paine zuva rakasimba, mune semi-mumvuri. Dyara uri chinhambwe chemamita matanhatu kusvika matanhatu kubva pamadziro, pombi, nezvimwe.
- Pasi: inokura muvhu rakaorera, rakapfuma mune zvakasikwa, uye nyowani.
- Kudiridza: ingangoita 3-4 nguva pasvondo muzhizha, uye zvimwe zvishoma zvasara.
- Vanyoreri: muchirimo nezhizha na Organic mafetiraiza.
- Kuwanza: nembeu munguva yechando (dzinofanirwa kutonhora dzisati dzamera).
- Rusticity: inoramba kusvika -18ºC, asi haigare munzvimbo dzinopisa kana mune idzo dzinopisa kwazvo. Munzvimbo dzakaita seMediterranean, semuenzaniso, inogona kungorimwa pasina matambudziko munzvimbo dzemakomo.
