Mtunduwu unalandira dzina kuchokera ku chi Greek "pachys", omwe amatanthauzira kuti "wakuda", ndi "stachys" kutanthauza "khutu". Pahistahis amadabwa ndi mawonekedwe a inflorescence. Bracts yowala imakhala ndi chikasu chachikasu kapena chikasu-lalanje ndipo imakhala yofanana. Mwa izi, maluwa ang'onoang'ono akuyera, amapanga inflorescence pafupifupi masentimita 10. 15-20 inflorescences amatha kuphuka pa mtengo umodzi. Maluwa otchedwa pahistahis siatalika, koma ngakhale atatha kufota ndi kugwa maluwa mu inflorescences amakhalabe mawonekedwe okongoletsa kwa masabata angapo. N'zotheka kukwaniritsa nthawi yaitali maluwa kuyambira April mpaka August.
Pakhystahis chomera chachikulu, chofikira mamita 1 m'litali, chimakhala ndi mphukira yoonda kwambiri. Masambawa ndi aakulu, ovunda, amasonyeza nsonga, mdima wobiriwira, womwe uli pafupi. Kunja, pahistahis ndi ofanana ndi aphelandra, ngakhale kuti alibe masamba okongoletsera. Pakhistahis ndi odzichepetsa, ndi osavuta kusamalira zomera. Chikhalidwe cha biennial chimalimbikitsidwa kuti chikule muzikhalidwe, monga momwe kulima kwa nthawi yayitali gawo lochepa la mbewu likuwonekera bwino, ndipo limataya kukongola kwake. Ngati iwe udzakhala mwini wa chomera chodabwitsa ichi, ndiye kuti uyenera kudziwa momwe ungasamalire zinyumba zapansi pahistahis.
Mitundu.
Pakhistahis chikasu (Chilatini cha Pachystachys lutea Nees) - theka la shrub pafupi mamita 1 okwera. Kuwombera kumayima, pansi pa lignified. Masamba ndi obiriwira obiriwira, opangira maola ndi zothandizira. Mipiringi ya mapepala: 14-20 masentimita m'litali, 4-7 masentimita m'lifupi. Pahistahis chikasu - chomera chobiriwira, ndi mawonekedwe abwino okhudza khumi opicate inflorescences. Maluwa okongola ali ndi mawonekedwe odabwitsa: iwo ndi amuna kapena akazi okhaokha, osakanikirana kwambiri, chifukwa cha zomwe zimafanana ndi mulomo wotseguka. Iwo amatsegulidwa panthawiyo, kuyambira pansi mpaka pamwamba pa inflorescence. Mitundu yamitundumitundu ndi yayikulu, yonyezimira yachikasu, yomwe inalandira dzina lake la mitundu. Odziwika ndi yaitali maluwa nyengo ku kasupe mpaka autumn.
Kusamalira zomera pahistahis.
Kuunikira. Pahistahis amakonda kuwala kowala, kupewa kuwala kwa dzuwa. Malo abwino kwambiri okonzekera kwake ndi mawindo akumadzulo ndi kummawa. Ndipo ngati muli ndi mawindo akumwera, muyenera kupanga chitetezo ku dzuwa monga mawonekedwe kapena mapepala opangidwa. M'nyengo yozizira zomera zimasowa kuunikira bwino.
Kutentha kwa boma. M'chaka ndi chilimwe, zomera zimakonda kutentha pafupifupi 20 ° C. Ngati kutentha kumadutsa 24 ° C, chinyezi chiyenera kuwonjezeka. M'nyengo yozizira, kutentha kotereku ndi 16-19 ° C. Pahistahis sakonda mpweya wotentha, kotero simungakhoze kuuyika pafupi ndi zipangizo zotentha. Dziwani kuti ngakhale kuti chomeracho chikusowa mpweya watsopano, ndizowopa kwambiri zojambula. Choyamba choyambira pa pulogalamuyi ndi kutaya masamba osayembekezereka.
Kuthirira. M'chaka ndi chilimwe, zimalimbikitsidwa kuthirira madzi pahistahis mochuluka, mwamsanga pamwamba pa dziko lapansi. M'nyengo yozizira, madzi okwanira amachepetsedwa kukhala osakwanira: kuthirira madzi atatha masiku 1-2 mutatha mpando wosanjikiza wa gawolo. Kumbukirani kuti mulimonsemo ndizosatheka kuthira pansi gawo lapansi, nthaka iyenera kukhala yonyowa. Chomeracho chimapweteka kwambiri kuumitsa kwa dziko lapansi.
Kutentha kwa mpweya. Pahistahis amakonda kwambiri chinyezi, choncho ayenera kupopedwa nthawi ndi nthawi chaka chonse. Kuti muchite izi, gwiritsani ntchito madzi osasunthika kapena osankhidwa. Mu mpweya wouma kwambiri m'nyumba, zimalimbikitsa kupopera 1-2 pa tsiku. Kuti muwonjezere chinyezi, yikani mphika pa khola lodzaza ndi dothi lopaka madzi, moss, kapena miyala.
Kupaka pamwamba. Kupaka kwapamwamba kumachitika kamodzi pa masabata awiri, kuthirira madzi okwanira musanayambe. Ambiri amagwiritsidwa ntchito.
Mapangidwe a korona. Kusamalira izi m'nyumba zowonjezera kumaphatikizapo kudulira panthawi yake ndi prischipku, cholinga chake ndikupanga korona wokongola. Pangani chomera chimayamba ndi msinkhu. Chosowachi ndi chifukwa chakuti mu chilengedwe cha pahistahis akulimbana ndi malo awo pansi pa dzuwa, motero amakula mofulumira popanda kugwiritsa ntchito mphamvu pa nthambi. Ndipo amangokwana masentimita 80 m'litali, chomera chimayamba kugwira ntchito. Ngati malo a pahistahis akukula, mapangidwe a korona amtsogolo ayenera kuyamba m'chaka choyamba cha moyo wa chomerachi. Kudulira koyamba kumalimbikitsidwa pamtunda wa masentimita 11-15 kuchokera pansi. Opaleshoniyi ndi yosavuta: Kuchokera pamphuno pamapeto pake timapepala timatatu timatulutsidwa, komanso, ndi mpata wotsatira wa mphukira. Pamapeto pake, mutachita izi katatu mu chaka choyamba, m'nyengo yozizira mudzalandira chomera chokhala ndi mapepala 9-12. Pambuyo pa nyengo yozizira, muyenera kudula kapena prishchipku nsonga zonse. Chifukwa chakuti nsonga iliyonseyi idzapereka mphukira zosachepera ziwiri, mudzakhala ndi pahistahis ndi mapepala 18-24. Chomera choterocho chiyenera kukonzekera maluwa. Onaninso kuti nthambi zowonongeka zidzasiyanitsa zokhazokha ndikukhalanso pachimake. M'chaka cha chaka chamawa, muyenera kubwereza pinch.
Kusindikiza. Pahystahis ayenera kuikidwa m'chaka cha chaka chilichonse, kudulira. Pachifukwa ichi, gawo lapansi lazomwe likugwiritsidwa ntchito: dothi-kuzungulira nthaka (magawo awiri), peat (gawo limodzi), tsamba (gawo limodzi), humus (gawo limodzi) ndi mchenga (gawo limodzi). Tikulimbikitsidwa kuwonjezera zidutswa zamakala kwa osakaniza. Kumbukirani kuti pahistahis imakondweretsa nthaka yonyowa, choncho mumayenera kukhazikitsa madzi abwino kuti musayang'ane. Lembani pahistahis makamaka vegetatively (cuttings).
Zovuta za chisamaliro.
Ngati chomera chikutsikira masamba, ndiye kuti pahistahis ikuyimira. Chifukwa china chingakhale chosakwanirira kuthirira mbewu.
Ngati nsonga za masamba zikuuma, ndipo masamba ayamba kupotoza, ndiye chipinda ndi mpweya wouma kwambiri. Fulutsani chomera tsiku ndi tsiku, mwinamwake sichidzasiya pachimake.
Ngati pachystachis imabala pansi pa tsinde, ndiye kuti ikufunika kubwezeretsedwanso ngati kudulira kanthawi kochepa. Dulani mphukira akhoza kudula ndi kubzalidwa.
Ngati zidutswazo zimayamba kutayika ndipo sizingatengere mizu kwautali, dulani masamba aakulu pakati ndikuyika zidutswazo pamalo otentha.
