I-catalpa isihlahla esihle esivuthuluka esinomqhele obanzi. Ngamaqabunga amakhulu, aluhlaza kanye nezimbali ezimhlophe ezihluma ngamaqoqo, lesi sitshalo esithakazelisa kakhulu ukukhula engadini.
Ikhula ngezinga okuthi, ngaphandle kokuba phezulu kakhulu, kusivumele ukuthi sibone izinguquko eziphawulekayo unyaka nonyaka. Yini enye, Iyakwazi ukuhlala kuma-microclimate ahlukahlukene, inqobo nje uma usesifundeni lapho kuhlukaniswa khona izinkathi ezine zonyaka.
Isiphi isitshalo i-catalpa?
ICatalpa bignonioides 'Aurea'
UCatalpa, ogama lakhe lesayensi ngu ICatalpa bignonioides, Isihlahla esivuthulukayo esidabuka eningizimu-mpumalanga ye-United States esifinyelela kumamitha ayi-15-20 ukuphakama.. Inesiqu esicishe sihlale siqondile, esingafika kumitha elingu-1 ububanzi, kanye nomqhele onamagatsha amaningi owakhiwe ngamahlamvu amakhulu, afinyelela kumasentimitha angama-30 ububanzi namasentimitha angama-20 ubude. Lezi zine-glabrous beam kanye ne-tomentose engaphansi.
Izimbali zawo ziyaqhakaza entwasahlobo, ehluma esiqwini sezimbali esinamagatsha esakha i-panicle, eyisiphetho; okungukuthi, liyafa ngokushesha lapho lingasadingeki, into eyenzekayo lapho izithelo ziqeda ukuvuthwa noma lapho izimbali ezinganayo impova zibuna futhi ziwe. Lezi zimbali zimhlophe, futhi isithelo siyi-capsule emide, efana ne-legume noma i-pod, engaba amasentimitha angu-30 ubude kodwa ingafinyelela amasentimitha angu-50.
Imbewu inamaphiko, amasentimitha angu-2-4 ubude kanye nombala onsundu-beige okhanyayo. Ziyakwazi ukusebenza iDemo, ngakho kufanele zitshalwe ngokushesha ngangokunokwenzeka ukuze ziqhume.
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
Kumele ibe ngaphandle ukuze uzwe ukuhamba kwezinkathi zonyaka futhi ngaleyo ndlela wazi ukuthi kufanele ukhule nini, uqhakaze, noma uphumule kuze kubuye intwasahlobo. Ngaphezu kwalokho, kuhle ukunikeza ukukhanya kwelanga okuqondile ingxenye enhle yosuku, kodwa ibekezelela umthunzi we-semi-shade 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. lapha) noma la arlita (kuyathengiswa lapha).
- Imbiza yezimbali: uma uzoyikhulisa embizeni isizini eyodwa, ungasebenzisa i-universal substrate, noma i-mulch ene-perlite engu-30% (iyathengiswa lapha).
Ukunisela
I-catalpa isihlahla esidinga amanzi, hhayi njalo, kodwa njalo. Akusona isitshalo esibekezelela isomiso, ngakho-ke ngeke kube wumqondo omuhle ukusitshala endaweni lapho imvula enetha kancane. Empeleni, kufanele ithole amanzi (kungakhathaliseki ukuthi avela emvuleni noma ngokuchelela) okungenani izikhathi ezi-3 ngeviki ehlobo, futhi unyaka wonke, njengoba izinga lokukhula kwawo 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
Kufanele ikhokhwe phakathi nenkathi yokukhula, okungukuthi, kusukela entwasahlobo kuya ekuqaleni kwekwindla, usebenzisa umanyolo we-organic, njenge-earthworm humus (ukuthengiswa lapha), umquba wenkukhu (omile) noma inkomo, umquba.
Uma sinayo ebhodweni, ngincoma ukusebenzisa umanyolo owuketshezi, njenge-guano owuketshezi (uyathengiswa lapha), noma izivundisi ezifana ne-universal (iyathengiswa lapha) noma izitshalo eziluhlaza (ziyathengiswa lapha).
Ukuphindaphinda

i-catalpa iphindaphindeka ngembewu ngesikhathi sasentwasahlobo, futhi nangokusikwa okungamapulangwe ehlobo. Ngembewu kulula, ngoba kufanele uyihlwanyele ebhodweni noma, kangcono, ethreyini yamahlathi, ene-substrate yendawo yonke (iyathengiswa. lapha), amanzi abeke endaweni enelanga.
Ama-cuttings akhethiwe kufanele asuke emagatsheni anonyaka owodwa ubudala, aqala ukugqama kodwa asathambile. Ngaphezu kwalokho, kufanele zilinganise cishe amasentimitha angama-40 ubude, futhi isisekelo sazo kufanele sifakwe amahomoni e-rooting (ayathengiswa. lapha) ukuze bangene ezimpandeni. Ngemuva kwalokho, zitshalwa ezimbizeni ezine-vermiculite (zithengiswa lapha) iphuziswe ngaphambilini, futhi igcinwe endaweni engaphansi komthunzi.
Izihlahla
Akukhuthazwa ukuthena, njengoba i-catalpa ingase ilahlekelwe ingxenye yobuhle bayo bemvelo. Mhlawumbe susa amagatsha aphukile noma abukeka kabi, kodwa akukho okunye. Lokhu kungenziwa ngasekupheleni kobusika.
Ukutshala nini i-catalpa?
Ingatshalwa emhlabathini noma ifakwe kabusha sekwephuzile ebusika, lapho ubona ukuthi izikhupha ziqala ukuvuvuka noma kancane ngaphambili. Kufanele ukwenze ngokucophelela, uzama ukungasebenzisi izimpande kakhulu. Ngale ndlela, izokwazi ukululama kangcono ekufakweni futhi, ngakho-ke, izoqala kabusha ukukhula kwayo kusenesikhathi.
Izinhlupho nezifo
Iqine kakhulu. Kodwa ingaba nama-aphid, mealybugs kanye nesikhunta njenge powdery mildew noma iPolyporus, evame ukufika phakathi kwesihlahla ngamanxeba okuthena. Izinambuzane ziphathwa ngama-insecticides athile, kanye nesikhunta ngama-fungicides (iyathengiswa Ayikho imikhiqizo etholiwe.) kodwa futhi ukuchelela kuphela lapho kudingekile futhi nokugcina isitshalo sinakekelwe kahle.
Isibindi
Imelana nesithwathwa ukuya ku-15ºC, kanye nezinga lokushisa eliphezulu elingu-35-38ºC uma unamanzi. Ingahlala ezindaweni lapho isithwathwa sibuthakathaka khona.
