IWashingtonia isihlahla sesundu esidumile, ukuphakama kwako endaweni yemvelo kufinyelela ngaphezu kwamamitha angama-20. Izinhlobo zaseWashington ziyefana kakhulu, kepha ngasikhathi sinye sinezinto ezithile ezihlukile. Lesi sitshalo singesomndeni iPalm (Palmae). Ukusakazeka kusuka eningizimu-ntshonalanga Melika, kanye nasenyakatho nentshonalanga yeMexico. Igama lesihlahla sesundu lanikezwa ukuhlonipha uMongameli wokuqala waseMelika, uGeorge Washington odumile.
Incazelo yemvelo
Isitshalo sikhula ikakhulukazi ezifundeni lapho isimo sezulu saseMedithera sikhona. Izinhlobo ezimbili ezikhona zezihlahla zesundu zaseWashington ezindaweni zazo zemvelo zingamelana neqhwa lesikhashana elingeqi ama-degrees ayi-12.
Ekuqaleni, iWashington yayisetshenziswa njengesitshalo sokuhlobisa kuphela emadolobheni aseCalifornia, kwezinye izimo eFlorida. Kunzima kakhulu ukuyikhulisa ezimweni zamakamelo, endaweni enjalo lolu hlobo lwesihlahla sesundu aluqhakaze. Ekwakhiweni kwangaphakathi, izimo ezincane kakhulu zivame ukusetshenziswa. Noma kunjalo, kuvulandi noma engadini, uma isimo sezulu sivuma, lesi sitshalo sikhula ngempumelelo.
Kungakuhle ukuthi ubhekisise ukuthi iWashington ayilungele indawo yezimboni ezingamapulani, ngoba ayikubekezeleli ukungcoliswa komoya okuphezulu.
Ukubukeka
Uma izinhlobo zezihlahla zesundu zaseWashington zikhula endaweni yemvelo, khona-ke lezi izitshalo ezinde ezinamaqabunga amakhulu. Lesi sitshalo sinezimbali ezinama-inflorescence, cobs kanye namaqabunga, ububanzi bawo bufinyelela kumamitha ayi-1.5. Isiqu sesundu asisihlanga, siphuzi ngombala, ukuphakama asidluli kumamitha angama-30. Amaqabunga amadala kungenzeka angawa isikhathi eside, ngenxa yalokho isiqu saso simbozwe "ngesiketi" esiminyene.
Lesi sitshalo singenye yezihlahla zesundu zabalandeli, njengoba amaqabunga awo ethatha fan. Izithelo ezivelayo zinesimo esiyindilinga, zinomzimba impela, imbewu inesilima. Ngokuvamile zithandwa izinyoni ezigoqayo.
Izinhlobo zaseWashington
Zimbili kuphela izinhlobo zezihlahla zesundu ezingahlobo lwazo:
- I-Washingtonia nitenosa (i-Washingtonia filifera). Igama lalezi zinhlobo lihunyushwa lisuselwa esiNgisini ngokuthi "fan of californian fan." Lokhu kungenxa yokuthi ekuqaleni lesi sitshalo sikhula kuphela ogwadule lwalesi simo. Kulezi zindawo, iWashington engcolile, njengoba ibizwa nangokuthiwa, yakha amahlathi futhi ifinyelela ukuphakama kwamamitha angama-20. Amaqabunga awo aluhlaza-grey anombala obophelelekile kunalokho, anemicu emincane yombala omhlophe. Lesi kwakuyisizathu sokuvela kwegama lale nhlobo. Izimbali zesitshalo ziqoqwe ku-panicle inflorescence. Ebusika, lesi sitshalo sincamela amazinga okushisa aphansi - kuze kube ngama-15 degrees.
- I-Washingtonia enamandla (i-Washingtonia robusta). Luhlobo lwendabuko eMexico. Emvelweni, isihlahla sesundu esinjalo sifinyelela ekuphakameni okumangazayo okungafika kumamitha angama-25. Kodwa-ke, ububanzi be-barrel ngokwako buhlala buqine futhi abudluli kuma-70 cm. Ngokungafani nohlobo lwangaphambilini, iWashington iqinile, njengoba ibizwa nangokuthi, iphuma nomqhele osabalele kakhulu. Amaqabunga awo awawona amakhulu kangako, aluhlaza okotshani ngombala, awunamicu, kepha kukhona ama-spikes abukhali kucezwana lamaqabunga. Izimbali zalolu hlobo zithola umbala opinki, ama-inflorescence amade. Isundu liyazwela emazingeni okushisa aphansi, ngakho-ke kufanele lihlale lifudumele ngesikhathi sokuwa.
Amathiphu Wokunakekela
Ukuze isitshalo sikhule ngesigqi esijwayelekile, kufanele kunikezwe imibandela ethile. IWashingtonia idinga ukukhanya okukhanyayo, ehlobo izinga lokushisa kufanele okungenani libe ngama-20 degrees. Ngokuqondene nomswakama womoya, ama-55% azokwanela, kanti umkhawulo omkhulu ngu-75%. Umuthi wesundu uphendula kahle emoyeni omusha, ngakho-ke, lapho kuphela intwasahlobo kungakuhle ukuwudlulisela engadini. Ngasikhathi sinye, kufanele ivikeleke kokusalungiswa, kanye nezulu, ngoba lezo zimo zizolimaza iWashington kuphela. Uma uyikhulisa endlini, lapho-ke kufanele ukhethe amakamelo afudumele nalawo akhanyiswe kakhulu. Izihlahla zesundu ezindala kuphela ezingamelana nokukhanya okukhanyayo.
Ezikhathini ezifudumele zonyaka, ukuthambisa okuningi kuyadingeka. Ukuze wenze lokhu, kunconywa ukusebenzisa amanzi afudumele. Ukunisela kufanele kwenziwe ngezikhathi ezithile ukuze ingaphezulu lomhlaba lome. Ebusika, ungazikhawulela ukunisela kwe-sparse, ngakho-ke ukomiswa kwesikhashana esifushane ngeke kulethe ukulimala. Noma kunjalo, ukomisa okuqinile kwenhlabathi kufanele kugwenywe.
Ehlobo, kungakuhle ukuthi kulondolozwe izinga eliphezulu lomswakama egumbini lapho kukhula iWashington. Ukuze wenze lokhu, ungafafaza izitshalo. Uma izinga lokushisa lasekamelweni lingaphezu kwama-20 degrees, isitshalo singamelana nezimo ezinjalo, kodwa ngentuthuko engcono kungcono ukuyifaka esikhwameni ngetshe elimanzi. Kulokhu, kufanele usule njalo amaqabunga othulini. Ukwenza isihlahla sesundu simbozwe ngokulinganayo ngamaqabunga, ungasandisa sihlobene nomthombo wokukhanya kwemvelo.
Ngokukhula okujwayelekile kwesundu, ungasebenzisa i-substrate eseqediwe. Ukugqoka okuphezulu kufanele kwenziwe ngesikhathi sentwasahlobo-ehlobo, cishe kanye njalo ezinsukwini eziyi-15. Kulokhu, ukusetshenziswa kwamanyolo owenziwe ngomumo owenziwe ngetshezi, enzelwe ukufaka umquba, kuvunyelwe.
