Okuvamile emasimini ethu ungahlangabezana nalesi sitshalo esithakazelisayo - i-rodzersiyu, nakuba ijwayele kusukela ekhulwini leshumi nesishiyagalolunye, lapho ifike ezweni lethu livela eChina . Kuyimangaliso yemvelo ekudumiseni indoda eyayiqondisa uMbuso WaseCelestial - uJohn Rogers.
Lesi sitshalo esingapheli iminyaka embalwa siyakhula kakhulu, ngakho-ke sidinga indawo enkulu yokutshala. Amaqabunga ama-brown-burgundy noma ama-emerald, lapho i-rodzersiya ekwaziswa khona futhi ehlonishwayo engadini ye-diameter enhle kakhulu. Kodwa izimbali ngokuphambene - ezincane, eziqoqiwe kwi-paniculate inflorescences futhi ziyakubonga zingaba cishe inyanga kusukela ngoMeyi kuya kuJuni.
Izinhlobo nezinhlobonhlobo ze-rogernia
Namuhla, abalimi bethu bahlakulela izinhlobo ezine ezidumile kakhulu ze-rogiersia:
- I-elderberry iyizinhlobo ezingavamile, okungafani nezinhlobonhlobo zama-congeners eziphakathi kwehlobo; Izimbali ezincane ezimhlophe zesimo esingavamile ziphunga iphunga elimnandi;
- i-lamellar - uhlobo olungavamile kakhulu lwe-rosergesia, amaqabunga awo afana nezitsha ezinkulu, futhi ezihlukahlukeneyo azizithobeki ekunakekeleni;
- cirrus - uhlobo oluthile lweRogersia ngezimbali ezincane ze-pink, ezisezingeni eliphezulu;
- i-chestnut-leaf - izinhlobo ezivame kakhulu, ezaba negama layo ngokufana namaqabunga omuthi ofanayo; kanye ne-rosacea cirrus, i-blooms in pink, futhi ikhetha ukukhula emaphethelweni emzimbeni wamanzi nemvelo.
Indawo yokutshala
Ukuze Rogersia ibonise ubuhle bayo obugcwele ngokugcwele, kuzodingeka ukuthi ucabange ngokucophelela ngendawo. Phela, lesi sitshalo asiwuthandi ilanga, kodwa ku-penumbra sikhula kahle, sijabulisa iso nge-shade yamahlamvu angavamile.
Umhlabathi wesitshalo uzohambisana ne-loamy, kodwa unomsoco ngokwanele. Ngaphezu kwalokho, isayithi okuhlongozwa ukuthi isitshalo sitshale kufanele sivikeleke kahle emoyeni ngesikhathi sebandayo.
Lesi sitshalo siphendula kakhulu ekutheni, kodwa kungcono nakakhulu uma izitshalo zitholakala emzimbeni wamanzi, ngoba lapho umoya ogcwele umswakama unomphumela omuhle kakhulu ekukhanyeni kwamaqabunga.
Ukunakekela i-rodgersia
Lesi sitshalo singahle sibekwe ngokuphepha njengendlela elula neyinkinga. Uma utshala i-rodgersia emhlabathini ovulekile, ukunakekelwa kwayo kunciphisa kuphela ukuchelela okuvamile nokuningi, ngaphandle kokuthi isitshalo asiyikukhula. Ngendawo efanele, lesi sitshalo sokuhlobisa sihlala ngaphandle kokufakelwa kuze kuphele iminyaka eyi-10.
Ngaphezu kokuchelela okunengi ngesikhathi sehlobo, umvunyi uzodingeka nje asuse amaqabunga omisiwe nama-peduncles uma sekuphelile. Ngenxa yokuthi uRogersia cishe ayithinteki izinambuzane, ungakhohlwa mayelana nokwelapha nge-fungicides ekhoneni legadi noma imbali yezithelo. Ngokuvamile, uRogersia ubekezelela kahle ubusika ngaphansi kweqhwa elikhulu leqhwa. Kodwa uma kungakafiki, futhi amaqhwa awasekude, kufanele umboze izitshalo ngamaqabunga noma i-lapnika. Ezindaweni ezisenyakatho lapho kukhona usongo lokuqhwaza, kungcono ukubeka ama-rhizomes ekwindlabeni emgodini esitsheni nge-sawdust noma umhlaba, njengoba sasivame ukukwenza nama- dahlias .
Ukukhiqiza
Ukufakelwa kwe-Rodgersia kwenziwa yonke inkathi yehlobo, nakuba isitshalo esisha singcono kakhulu etshalwe entwasahlobo. Ukuze usakaze isihlahla, kubalulekile ukumba ingxenye edingekayo ye-rhizome ngefosholo, ngokuyisika kahle. Imbewu ye-rodsya isakazekile, ngoba le nqubo ide kakhulu futhi iyinkimbinkimbi.
Kungani izimbali zingaqhakazi?
Futhi nakuba lonke ubuhle besitshalo lisemahlamvu, hhayi izimbali, abalimi abaningi abangenalwazi bakhathazeke ngokuntuleka kwezimbali. Lokhu kungenzeka uma lesi sitshalo singekho okuthile noma kusukela ekudleni okukhulu. Ukuthola lokhu kungatholakala kuphela ngokubuka isihlahla.
Kwenzeka ukuthi umhlaba ugcwele kakhulu nge-nitrogen, ngakho-ke amahlamvu akhula ngokumangalisayo, kepha ngenxa yezimbali. Noma okokuqala kusukela entwasahlobo kwakukhona ukuchelela okungavamile nokunganele, futhi i-rozdersiya ayikwazanga ukubeka amafihledi. Uma indawo yesitshalo ikhethiwe ayiphumelelanga - ilanga elikhanyayo noma eliphansi, lapho izimpande zifile, khona-ke izimbali azikwazi ukulinda.
