Iingcali zenzululwazi, xa ziqala ukumbona esi sityalo, ngoko wahlula njengesihlobo esiseduze, esaziwayo kwaye sithandwa kwiYurophu vinca, ngoko wayekulo hlobo lwesityalo. Kwangexesha elide lesi sityalo sabizwa ngokuthi iMadagascar, okanye i-pink, periwinkle. Kodwa kamva i-botanist yajonga ngokugqithiseleyo kwaye yaqonda ukuba ayiphutha, ukuba lo akayena umzalwana we-periwinkle, kodwa ngumzala kuphela.
Le ntlobo yokuqala yafudukela kwi-genus Lochner, yafudukela kwi-Ammocallis, kwaye ngowe-1837 yawela kwi-genus ye-cataract. Nangona iinqununu zenze umyalelo wokuhlelwa kwezihlomelo, esi sityalo sisetyenziselwa ukubiza i-pink vinca, okanye i-periwinkle ebomvu, igama elichanekileyo (catarratus) igama kwaye alisoloko lisetyenziswa namhlanje.
Inhlobo yeCattratus ineentlobo zezityalo eziyi-8, ezininzi zazo zihlala eMadagascar. Isityalo sikhula e-Indochina, eIndiya, kwiziqithi zaseStrat Mauritius, eJava, ePhilippines, eCuba, eMadagascar, naseRunion.
Kwimimandla ekumntla kubonwa njengendawo yokuhlala yangaphakathi. Kungekudala kudla ukusetyenziswa ukuhlobisa iziqhamo zangaphandle kwenkcubeko yonyaka omnye. Isityalo sihlonywa kwi-Western Transcaucasia, eKazakhstan naseKuban.
Ukunyamekelwa kwesityalo.
Indawo: ilanga, likhuselekile kwimimoya, indawo efudumeleyo. Izityalo ze-catarrhtus zangaphakathi akufanele zityalwe kwintsimi yeentyatyambo, kungenjalo kwimvula yezulu, izityalo zingenako ukuphuphuma umoya.
I-Substrate: i- fertile, i-well-moistened, ngaphandle kweetyuwa ngaphezulu, i-pH ibe yi-5.5-5.8.
Umxube womhlaba sithatha inxalenye elinganayo yamagqabi kunye nomhlaba we-sod, i-peat, i-distillation kunye nesihlabathi.
Umswakama weposi ayifunanga isityalo, kuba kwindawo enqunyanyisiweyo umhlaba utyhala ixesha elide, kwaye lo luhlobo lwenzuzo.
Izixhobo zokulima: E-UK, isityalo sandisasazeka ngaphambili kunase-Yapekazi yaseYurophu. E-Netherlands, isityalo sifakwa kumagumbi akhethekileyo, ukhuselwe kwimimoya.
I-Cataracts zezityalo ezilula ukukhula kwindawo yokulala, ngaphandle kokuba zizityalo ezinombulelo, ngoko ziya kuphendulwa kwinkathalo eninzi kunye nokude.
Khulisa isityalo esingcono kwiwindow ekhanyayo, kodwa kwindlela yokukhanya yelanga ilungele ukuba i-pritenyat. Kwakhona, isityalo kufuneka sifefe, sondliwe kanye emva kweentsuku eziyi-14-21. Ukugqoka okuphezulu kuqhutyelwa ngesisombululo se-fertilizer epheleleyo.
Ehlobo, isityalo ebhodweni singathathwa kwi-balcony, ngelixa kufuneka likhuselwe emoyeni, ubushushu nemvula. Ebusika, isityalo kufuneka sigcinwe kwindawo epholileyo kunye neqabileyo, eneqondo eliphezulu lokushisa kwama-10-15 degrees kunye nesibonakaliso esikhulu. Ngokuqala kwentwasahlobo, amasebe anqunywe kwi 1/3.
Ukuzaliswa: Ezi ntloplants zivelisa izityalo kunye nembewu. Ekupheleni konyaka wobusika, okanye ekuqaleni kwentwasahlobo, imbewu ihlwayelwe kwi-1-2 cm. Ukuhlwayela kuhlanganiswe ifilimu emnyama, kuba ukuhluma kweso sityalo kugcwele ubumnyama kuyimfuneko. Ukuba iqondo lokushisa lingama- 24 о С, emva kweentsuku ezili-10 kuya kubonakala izityalo. Iqondo lokushisa liyancipha ngokukhawuleza xa kubonakala izityalo, ngoko kufuneka zifakwe ekukhanyeni.
I-fertilizing yokuqala iyenzeka ubuncinane iintsuku ezili-14 emva kokuba ihluma ivele. Ngomanyolo, i-phosphorus ayifanele ibe yinto eninzi, kuya kuba ngcono ukuba i-nitrogen kwisichumisi ifom yefomati ye-nitrate.
Iipokto zenziwa ngokufanelekileyo xa isityalo sikhula ukuya ku-6-8 cm ukuphakama, kunye nobukho beemakhishithi ezine zangempela.
I-Cataract, iphinda ikhiqize ngoncedo lwezityalo eziluhlaza. Iinqununu zifakwe kwisanti ehlanjwe, ihlanganiswe ngesikhwama seplastiki okanye ingqayi. Iinqununu nazo zinokunika iingcambu kumanzi.
Ngama-prishchipke amancinci ama-catarrhtum imibono ahlukana. Imimandla yangoku-mfuneko ayifuni i-pinch, kuba uphawu lokunyuka kwindleko ku-genotype yabo. Nangona kunjalo, ukufumana isiqithi esingaphezulu, ama-catarrhtal amancinci kufuneka atyunwe amaxesha ambalwa. Isityalo sityalwe omnye komnye kumgama ongama-50 cm.
Ukusetyenziswa kwezityalo.
Izityalo zeCatarrhtas zisetyenziswe njengesigubungelo somhlaba ngenxa yokuba ziyakwazi ukusasaza ngokukhawuleza, zihlala kuyo yonke indawo engenakho, ngelixa zifihla iinjongo ngepetti eluhlaza. Ukuthandwa kwe-cataracts kubangelwa imfashiso ekhulayo yokuvelisa izityalo kwiimbobozi, ezazisetyenziselwa ukuhlobisa.
E-Indiya naseMadagascar, iipilisi zenkcubeko zasebenzisa i-cataracts ukuphatha isifo sikashukela, ukukhwehlela ukunciphisa uxinzelelo lwegazi, ukuphatha izicathulo ezahlukeneyo.
Iipropati zonyango zalesi sityalo zaba mnandi kubaphandi eCanada naseUnited States, emva kokuphela kweMfazwe Yehlabathi II. Bafunda ukuba amajoni asePhilippines ngexesha lemfazwe asebenzisa amaqabunga e-catarratus endaweni yoko-insulin engenakufikeleleka ngelo xesha.
Ucwaningo luye lwabonisa ukuba ukusetyenziswa kwezicatshulwa zezitshalo akukho ncitshiseko ekunciphiseni kwimizinga yeshukela yegazi. Nangona kunjalo, kwizilwanyana zebhubhoratri ezine-leukemia, kwakukho utshintsho olukhulu kwi-formula yegazi ukuze kube ngcono.
Emva kancinci, izazinzulu zakwazi ukukhishwa kwi-alkaloids ye-catarrhtal, enomsebenzi ochasayo. Ngesiseko sabo, ukuveliswa kwezidakamizwa ezilandelayo kwasungulwa: i-vincristine ne-vinblastine.
Amachiza anokwenziwe okwenziwe kwi-cataract, okanye ama-tinctures ahleliwe ngokuzimeleyo, kunye namafutha okugcoba, athetha ukunyanga, kodwa kaninzi ukuphazamisa iziphumo ezibi kakhulu. Ngoko ke, ukuba i-cataract isetyenziselwa unyango, ke ukubonisana kunye nolawulo lwegqirha kuyimfuneko.
