I-Catalpa (Catalpa bignonioides)

I-catalpa iyisihlahla esihle esikhula amahlamvu esinomqhele obanzi impela . Njengoba sinamaqabunga amakhulu aluhlaza kanye nezimbali ezimhlophe eziqhakaza ngamaqoqo, iyisitshalo esithakazelisa kakhulu ukusitshala engadini.

Ikhula ngesivinini esithi, nakuba ingekho phezulu kakhulu, isavumela izinguquko ezibonakalayo unyaka nonyaka. Ngaphezu kwalokho, ingachuma ezindaweni ezinezimo zezulu ezahlukahlukene , uma nje itholakala esifundeni esinezinkathi zonyaka ezihlukile.

Isiphi isitshalo i-catalpa?

I-catalpa, egama layo lesayensi yi- Catalpa bignonioides , iyisihlahla esikhula amahlamvu esidabuka eningizimu-mpumalanga ye-United States esifinyelela amamitha ayi-15-20 ukuphakama . Inesiqu esiqondile esifinyelela kumitha elilodwa ububanzi, kanye nomqhele onamagatsha amaningi owakhiwe ngamaqabunga amakhulu, afinyelela kumasentimitha angama-30 ububanzi namasentimitha angaba ngu-20 ubude. Lawa maqabunga anobuso obubushelelezi obungaphezulu kanye nengxenye engezansi ephansi.

Izimbali zaso ziyaqhakaza entwasahlobo , ziphuma esiqwini sezimbali esinamagatsha esakha i-terminal panicle; okungukuthi, siyafa ngokushesha nje lapho singasadingeki, okwenzeka lapho izithelo ziqeda ukuvuthwa noma lapho izimbali ezingakapholi zibuna futhi ziwela phansi. Lezi zimbali zimhlophe, kanti izithelo ziyi-capsule ende, efana ne-legume noma i-pod, engaba amasentimitha angama-30 ubude kodwa ingafinyelela amasentimitha angama-50.

Imbewu inamaphiko, inobude obungamasentimitha angu-2-4, futhi inombala onsundu okhanyayo no-beige. Ikhula isikhathi esifushane, ngakho-ke kumele ihlwanyelwe ngokushesha okukhulu ukuqinisekisa ukuthi iyahluma.

ukunakekelwa kwe-catalpa

Ungayinakekela kanjani i-catalpa? Uma ufuna ukuyithenga, noma usanda kwenza, futhi ufuna ukuhlinzeka ngokunakekelwa okungcono kakhulu, ngakho-ke sincoma ukuthi ugcine imininingwane elandelayo engqondweni:

Indawo

Kufanele igcinwe ngaphandle ukuze ikwazi ukubona izinkathi ezishintshayo futhi yazi ukuthi izokhula nini, iqhakaze, noma iphumule nini kuze kubuye intwasahlobo. Kunconywa futhi ukuthi ithole ukukhanya kwelanga okuqondile ingxenye enkulu yosuku, kodwa ibekezelela umthunzi ongaphelele ngaphandle kwezinkinga.

Akudingeki ukhathazeke ngezimpande zawo, ngoba azihlaseli. Kunoma yikuphi, awudingi ukutshala eduze kodonga, ngaphandle kwalokho isiqu saso sizoncika ngakolunye uhlangothi ukuze sifune indawo eyengeziwe yomqhele wayo. Ukuze ugweme lokhu, ukuhlukaniswa okungenani kwamamitha angu-4 noma ama-5 kufanele kushiywe phakathi kwephansi nodonga.

Umhlaba

• Isibindi: I-Catalpa ikhula emhlabathini ovundile. Khumbula ukuthi yesaba ukugcwala kwamanzi, ngakho-ke uma inhlabathi ihlangene kakhulu kuzodingeka uyixube ne-substrate enezimbotshana, njenge-pumice (iyathengiswa. Ayikho imikhiqizo etholiwe.) noma la arlita (kuyathengiswa Ayikho imikhiqizo etholiwe.).
• Imbiza yezimbali: uma uzoyikhulisa embizeni isizini eyodwa, ungasebenzisa i-universal substrate, noma i-mulch ene-perlite engu-30% (iyathengiswa Ayikho imikhiqizo etholiwe.).

Ukunisela

Isihlahla se-catalpa sidinga amanzi, hhayi njalo, kodwa njalo. Akusona isitshalo esibekezelela isomiso, ngakho-ke bekungeke kube umqondo omuhle ukusitshala endaweni enemvula encane. Eqinisweni, kufanele sithole amanzi (kungaba emvuleni noma ekuniseleni) okungenani kathathu ngesonto ehlobo , kanti unyaka wonke, lapho izinga lokukhula kwaso lehla kakhulu, kanye noma kabili ngesonto kuyokwanela.

Ngokusekelwe kulokhu, kubalulekile ukwazi isimo sezulu sendawo esihlala kuyo, noma okungenani sazi ukuthi imvula ivamise ukuna nini ukulungisa uhlelo lokunisela okufanele sililandele.

Umbhalisile

Ukuvundisa kufanele kwenziwe phakathi nenkathi yokukhula , okungukuthi, kusukela entwasahlobo kuze kube sekuqaleni kwekwindla, kusetshenziswa umanyolo wemvelo njenge-worm humus ( imikhiqizo engatholakali ithengiswa. ), umanyolo wenkukhu (owomile) noma umanyolo wezinkomo, umquba.

Uma kusebhodweni, ngincoma ukusebenzisa umanyolo owuketshezi, njenge-guano ewuketshezi ( Ayikho imikhiqizo etholakala ithengiswa. ), noma umanyolo ofana nowe-universal ( Ayikho imikhiqizo etholakala ithengiswa. ) noma umanyolo wezitshalo eziluhlaza ( Ayikho imikhiqizo etholakala ithengiswa. ).

Ukuphindaphinda

Izihlahla ze-catalpa zisakazwa ngembewu entwasahlobo, kanye nangokusikwa kwezihlahla eziqinile ehlobo . Ukusakazwa ngembewu kulula kakhulu; mane uzitshale ebhodweni noma, okungcono nakakhulu, ithileyi yembewu, usebenzisa ingxube yokubhaka yonke indawo ( akukho mikhiqizo etholakala ithengiswa ), manzisa, bese ubeka endaweni enelanga.

Izingcezu ezikhethiwe kufanele zibe ngamagatsha anonyaka owodwa ubudala aqala ukukhula kodwa asathambile. Kufanele abe ngamasentimitha angaba ngu-40 ubude, futhi isisekelo sawo kufanele simbozwe nge-rooting hormone ( Akukho mikhiqizo etholakalayo ethengiswayo. ) ukukhuthaza izimpande. Bese, zitshalwa ezitsheni ezine-vermiculite ( Akukho mikhiqizo etholakalayo ethengiswayo. ) ezike zaniselwa ngaphambilini, futhi zagcinwa emthunzini oyingxenye.

Izihlahla

Akukhuthazwa ukuthena , njengoba i-catalpa ingalahlekelwa ubuhle bayo bemvelo. Ungasusa noma yimaphi amagatsha aphukile noma abukeka enempilo, kodwa akukho okunye. Lokhu kungenziwa ngasekupheleni kwebusika.

Ukutshala nini i-catalpa?

Ungayitshala emhlabathini noma uyitshale kabusha ngasekupheleni kwebusika , lapho ubona amahlumela eqala ukuvuvukala, noma ngisho kusenesikhathi. Yenza lokhu ngokucophelela, uqaphele ukuthi ungaphazamisi izimpande kakhulu. Ngale ndlela, izolulama kangcono kusukela ekutshalweni futhi, ngenxa yalokho, iqale ukukhula ngokushesha.

Izinhlupho nezifo

Iqinile kakhulu. Kodwa ingaba sengozini ye-aphid, i-mealybugs, kanye ne-fungi efana ne-powdery mildew noma i-Polyporus , evame ukungena esihlahleni ngamanxeba okuthena. Izinambuzane zelashwa ngezibulala-zinambuzane ezithile, kanye ne-fungicides nge-fungicides ( akukho mikhiqizo etholakala ithengiswa ), kodwa futhi nangokunisela kuphela uma kudingeka nokugcina isitshalo sinakekelwe kahle.

Isibindi

Ingamelana neqhwa elifinyelela ku--15ºC, kanye namazinga okushisa aphezulu angu-35-38ºC uma amanzi etholakala. Ingaphila ezindaweni lapho iqhwa lilula khona.
