I-Sequoiadendron giganteum

Umbuso wezitshalo uqukethe izigidi zezinhlobo, kodwa uma kukhulunywa ngobukhulu, awekho odlula i- giant sequoia (i-Sequoiadendron giganteum ). Akusiwo umuthi omuhle kakhulu wengadi, ngaphandle kokuthi ingadi inkulu kakhulu, kodwa iqiniso liwukuthi, ikhula kancane futhi inhle kangangokuthi cishe akunakwenzeka ukungayitholi ngokushesha nje lapho uthola ithuba.

Uma lokho bekunganele, ngaphezu kobukhulu bayo obukhulu, ingenye yezitshalo eziphila isikhathi eside kakhulu: uma nje izimo zikuvumela, ingaphila iminyaka efinyelela ku-3200 , isikhathi eside kakhulu kunanoma yisiphi esinye isidalwa esiphilayo.

Uyini umsuka nezimpawu ze- I-Sequoidendron giganteum?

Lo mthi we-conifer omuhle kakhulu, owaziwa ngokuthi i-sequoia, i-giant sequoia, i-Sierra redwood, noma umuthi omkhulu, uwumuthi ohlala uluhlaza otholakala ezintabeni zaseCalifornia entshonalanga yeSierra Nevada. Ungafinyelela ukuphakama okuphezulu kwamamitha angu-94 nobubanzi besiqu obungaphezu kwamamitha angu-11 , yize uvame ukukhula ube cishe amamitha angu-50-85 nobubanzi besiqu obungamamitha angu-5 kuya kwangu-7.

Isiqu saso siqondile, sinegxolo elinemicu, futhi sinomqhele wamaqabunga amise okwe-awl akhula ngendlela ejikelezayo futhi alinganiselwa kumamilimitha angu-3 kuya kwangu-6 ubude. Ama-cone angamasentimitha angu-4 kuya kwangu-7 ubude futhi athatha izinyanga ezingu-18 kuya kwangu-20 ukuvuthwa, yize kungathatha iminyaka engu-20 ukukhulula imbewu yawo. Lawa mancane, angamamilimitha angu-4-5 ubude no-1 millimeter ububanzi, ansundu ngokumnyama, futhi anamaphiko ansundu ngokuphuzi asiza ukuba asuke kubazali bawo lapho umoya uvunguza.

Isebenzani?

I-sequoia enkulu isetshenziswa njengesitshalo sokuhlobisa kuphela . Esikhathini esidlule, bekukhona imizamo yokuthola ukusetshenziswa kwezinkuni zayo, njengokukhiqiza izingcezu zocingo, kodwa ibuthakathaka kakhulu kangangokuthi kulezi zinsuku ngingathi ayisetshenziswa kakhulu, uma isetshenziswa nhlobo, ngaleyo njongo (yize uma nginephutha, ngicela ungitshele 😉).

Uma ikhule njengesibonelo esiyingqayizivele, kuyamangalisa, ngoba uyazi ukuthi maduze uzoba nesihlahla esizogqama kwezinye. Futhi lokho akusho ukuthi, uma unethuba lokuzibona endaweni yazo yemvelo, ngokuqinisekile uzokujabulela.

Yini ukunakekelwa kwe-sequoia enkulu?

Lesi yisihlahla se-conifer esidinga isikhala esiningi kanye nesimo sezulu esipholile noma esifudumele . Sidinga ukuvikelwa elangeni lapho sisesincane, futhi sidinga ukujwayela kancane kancane ukuchayeka elangeni okwandayo.

Inhlabathi kumele ikhiphe amanzi kahle futhi, ngaphezu kwakho konke, icebile ngezinto eziphilayo. Ithanda inhlabathi ene-acid kancane, noma okungenani i-pH engathathi hlangothi , njengoba enhlabathini ene-alkaline ivame ukuba ne-iron chlorosis ngenxa yokuntuleka kwe-iron. Ngakho-ke, amanzi okunisela kufanele futhi abe ne-acid kancane, ngakho-ke ngincoma ukusebenzisa amanzi emvula, noma uma lokho kungatholakali, amanzi angena-lime eningi. Ukunisela kufanele kwenziwe ngezikhathi ezithile, njengoba kungabekezeleli isomiso.

Isakazwa ngembewu , ehlwanyelwa ekwindla emathileyi embewu ane-substrate yezitshalo ezithanda i-asidi, ebekwa ngaphandle emthunzini ongaphelele. Uma uhlala endaweni efudumele, kungcono ukuyihlukanisa esiqandisini ngokuyihlwanyela esitsheni se-Tupperware nge-vermiculite bese uyibeka engxenyeni yobisi, emakhazeni, njll. izinyanga ezi-3.

Okokugcina, kufanele ngikutshele ukuthi ingamelana namazinga okushisa afinyelela ku--30ºC , kodwa ayikwazi ukuhlala kahle ezindaweni ezifudumele ezinamazinga okushisa aphezulu.
