Lub herbaceous txhua xyoo, biennial lossis perennial nroj tsuag rudbeckia (Rudbeckia) yog tus sawv cev ntawm tsev neeg asters. Muaj kwv yees li 40 hom nyob hauv tus xeeb ntxwv no. Hauv qab ntuj qhov xwm txheej, cov paj zoo li no tuaj yeem nrhiav tau nyob rau ntawm thaj chaw hu nkauj ntawm North America. Hauv teb chaws Africa thiab Europe, nws yog cog tshaj plaws. "Dub-eyed Suzanne" - qhov no yog dab tsi thawj cov neeg tuaj txawv teb chaws tuaj rau North America hu ua cov nroj tsuag no vim tias muaj ib qho xim nruab nrab ntawm cov xim tsaus nyob rau inflorescence. Txawm li cas los xij, cov tib neeg nyob hauv Tebchaws Europe txiav txim siab tias lub npe "hnub lub kaus mom" haum rudbeckia ntau dua ua tiav. Cov nroj tsuag no muaj npe Rudbeckia K. Linnaeus hauv kev hwm ntawm Swedes leej txiv thiab tus tub Rudbeckes, uas yog botanists, thaum tus yau tshaj yog lawv tus kws qhia thiab phooj ywg ntawm Linnaeus, thiab kuj zoo-yawg-yawg ntawm A. Nobel, thiab nws muaj koob npe rau nrhiav cov tib neeg lymphatic system hauv 1653.
Cov yam ntxwv ntawm rudbeckia
Lub paj no tau tawg lossis yub yooj yim uas txhaws nruj, qhov siab ntawm uas tuaj yeem sib txawv li ntawm 0.5 txog 2 meters. Muaj cov tsiaj qus uas tuaj yeem ncav cuag qhov siab ntawm txawm 3 meters. Cirrus-faib lossis cirrus-dissected tag nrho cov nplooj ntoo muaj cov ovoid lossis oval duab. Lawv ntev ntev los ntawm 5 mus rau 20 centimeters, thaum nyob hauv nruab nrab sab qaum ntawm cov tua lawv yog sessile, thiab hauv qis dua lawv tau ntev-kav ntev. Qhov lub cheeb ntawm inflorescence pob tawb ncav cuag 15 centimeters, lawv suav nrog sterile marginal reed paj uas tuaj yeem ua xim hauv ntau qhov ntxoov daj, thiab zoo li bisexual median tubular paj pleev xim rau ntau yam xim (ntawm dub-ntshav los yog xim av rau daj). Cov txiv hmab txiv ntoo yog ib qho aconge-oblong, uas qee zaum muaj lub taub me me. Tsis loj heev cov ntsej muag zoo nkauj tsaus xim grey nyob ntev li 2 lossis 3 xyoos.
Loj hlob rudbeckia los ntawm cov noob
Tseb
Txhua hom thiab hom tsuas yog terry hom tuaj yeem nthuav tawm los ntawm noob. Thiab perennials tseem muab ntau los ntawm kev faib cov rhizome. Sowing noob yuav nqa tawm ncaj qha rau hauv av qhib. Qhov no yog ua tiav nyob hauv lub sijhawm thib ob ntawm Lub Rau Hli ntawm lub txaj npaj ua ntej. Qhov deb ntawm 15 centimeters yog khaws cia nruab nrab ntawm cov noob kis mus, nyob rau saum toj lawv yuav tsum tau sprinkled nrog ib txheej txheej ntawm av. Tom qab ntawd lub txaj yuav tsum tau watered nplua nuj, thaum nws yuav tsum tau maj mam muab txau nrog dej kom thiaj li tsis ntxuav cov noob. Nyob rau lub caij nplooj zeeg, cov nplooj me me rosettes yuav tshwm sim rau lub vaj, thiab lwm xyoo lawv yuav dhau los ua cov tuab ntoo uas yuav pib tawg me ntsis ua ntej tshaj li cov cog rau lub caij nplooj ntoo hlav. Nws tseem yuav tsum tau nyob rau hauv lub siab tias cov nroj tsuag no ua tiav nws tus kheej nthawv. Yog tias koj xav tau, koj tsis tuaj yeem ua ib yam dab tsi nrog qhov no, tab sis tsuas yog thaum lub caij nplooj ntoo hlav kom nyias tawm ntawm cov yub tawm thiab tsis tau quaj los nrog sowing
Muaj noob
Nws yog qhov ua tau kom loj hlob los ntawm kev cog paj ob qho tib si txhua xyoo thiab hnub nyoog ntawm rudbeckia. Sowing yog nqa tawm nyob rau hauv hnub kawg ntawm lub Peb Hlis los yog thawj - nyob rau hauv lub Plaub Hlis. Sow cov noob rau hauv cov thawv yub, thaum lawv txau rau saum nrog txheej nyias nyias thiab tsuas yog tso dej me ntsis nrog dej, siv cov tshuaj txau. Lub thawv yuav tsum tau them nrog ib zaj duab xis thiab pauv mus rau qhov chaw uas qhov ntsuas cua yuav nyob ntawm thaj tsam ntawm 20-22 degrees. Thawj cov tsiaj tuaj yeem pom hauv 7-14 hnub. Kom txog thaum cov yub pom tuaj, cov qoob loo yuav tsum tau muab ywg yog tsim nyog, nrog rau kev ua kom muaj cua tshuab thiab tshem tawm cov hws uas tau tshwm sim los ntawm qhov chaw nyob. Thaum cov yub txaij ua 2 daim nplooj ntawm cov nplooj nplooj tiag tiag, lawv yuav tsum cog kom zoo rau txoj hauv kev uas lawv tuaj yeem loj hlob ib txwm yam tsis cuam tshuam nrog ib tus. Thaum cov nroj tsuag tau noj hauv paus, koj yuav tsum npaj mus ua lawv tawv. Txhawm rau ua qhov no, lawv yuav tsum tau hloov pauv txhua hnub rau terrace lossis lawj rau ob peb teev.
Rudbeckia cog hauv av qhib
Cas lub sij hawm mus tsaws
Cov yub yuav tsum cog rau hauv av qhib hauv hnub kawg ntawm lub Tsib Hlis, tab sis tsuas yog tom qab nws paub tseeb tias hmo ntuj te yuav tsis rov qab los. Rau xws li lub paj, koj yuav tsum xaiv qhov chaw zoo uas muaj qhov permeable, cog cov av, noo nrog cov as-ham. Yog tias cov av yog av nplaum, ces cov xuab zeb tau tsim hauv qab nws rau kev khawb. Thiab hauv ib qho av ua ntej yuav pib rudbeckia nws pom zoo kom ua cov nplooj lwg. Thaum xaiv lub xaib, nws yuav tsum nco ntsoov tias cov nroj tsuag no ib txwm loj hlob thiab loj hlob nrog tsis muaj zog ntxoov ntxoo.
Tsaws Nta
Thaum cog nruab nrab ntawm tsob ntoo, qhov deb ntawm 0.3 txog 0.4 meters yuav tsum pom. Yog tias huab cua sov raug pom, ces cov paj uas cog yuav muaj hauv paus sai sai. Yog tias txoj hauv kev zoo nkauj txias (tshwj xeeb yog thaum tsaus ntuj), tom qab ntawd cov noob cog rau hauv qhov chaw qhib rau yav hmo ntuj yuav tsum tau npog nrog agrospan kom txog thaum nws siv paus. Rudbeckia, uas tau muab cov hauv paus, tuaj yeem tiv taus qhov kub tsis tshua muaj kev tiv thaiv vim tsis muaj tsev nyob. Thaum loj hlob ntau hom tsiaj thiab ntau xyoo, nws yuav tsum nco ntsoov tias xws li cov paj zoo tuaj yeem loj rau 3-5 xyoos ntawm qhov chaw nyob, yog li ntawd, tom qab cog, nws pom zoo kom cov av nyob hauv thaj chaw yog them nrog txheej txheej ntawm mulch (nplooj lwg), cov tuab uas yuav tsum tau txog 8 centimeters.
Kev saib xyuas rau cov pob txha ntev ntev ntawm rudbeckia
Nws yog ib qho tsim nyog los saib xyuas rudbeckia, zoo li ntawm rau cov paj vaj feem ntau. Nws yuav tsum tau watered nyob rau lub sijhawm thaum sawv ntxov lossis yav tsaus ntuj, thaum yog tias muaj huab cua kub ntev ntev, ywg dej yuav tsum tau mus. Nws tseem yuav tsum tau nco txog tias tom qab txhua qhov kev ntsuas dej, cov av tau xoob thiab, yog tias tsim nyog, txhauv. Yog hais tias qhov ntau los yog hom tsiaj siab, ces nws yuav tsum muab txoj hlua khi kom txhawb nqa. Thaum pib ntawm lub caij cog qoob loo, nws yog qhov tsim nyog los ua kom cov nroj tsuag zoo li qhov no; rau qhov no, cov tshuaj noj muaj txiaj ntsig nrog 1 thoob dej yog siv, nyob rau hauv uas ib diav loj ntawm poov tshuaj sulfate, nitrophoska thiab Agricola-7 yuav tsum tau yaj. Rau 1 square meter ntawm lub xaib, 3 litres ntawm cov tshuaj no tau tshwm sim. Tom qab ib lis piam ob zaug, Rudbeckia yog noj rau zaum ob siv cov khoom noj zoo tib yam. Thaum lub inflorescence pib fade, nws yuav tsum tau nraus nrog ib feem ntawm lub peduncle mus rau sab saud nplooj noj qab haus huv phaj.
Hloov Mus
Nyob rau hauv qhov kev tshwm sim uas, yam tsis muaj qhov hloov ntshav, xws li lub paj tawg rau ntau tshaj 5 xyoos, tom qab ntawd ntom ntom ntom ntog hauv nws, uas ua rau txhaws ntawm qhov chaw. Yuav kom zam tau qhov no, hloov khoom siv yuav tsum ua lub sijhawm. Khawb cov nroj tsuag thiab faib nws mus rau hauv qhov chaw, uas tom qab ntawd cog rau ntawm lub txaj tshiab, thaum nco ntsoov tswj kom muaj qhov tsim nyog nyob deb ntawm cov hnoos qeev. Nws tseem yuav tsum tau coj mus rau hauv tus account tias faib lossis hloov yuav tsum tau nqa tawm kom txog thaum lub sijhawm thaum kev hnyav ntawm lub hav txwv tau pib. Yog li ntawd, nws raug nquahu kom ua qhov no thaum lub caij nplooj ntoo hlav ntxov lossis thaum lub rudbeckia yuav ploj mus.
Chaw Sau Ntawv
Yuav ua li cas propagate xws li cov nroj tsuag los ntawm cov noob, nrog rau kev faib cov hav txwv yeem yog tau piav saum toj no. Lwm txoj kev yug me nyuam tsis muaj nyob.
Kab mob thiab kab tsuag
Rudbeckia yog qhov tsis tshua muaj kev cuam tshuam los ntawm powdery mildew. Nyob rau tib lub sijhawm, ib txheej tsis khov ntawm cov xim dawb tshwm rau ntawm cov av hauv av. Txhawm rau kho cov kab mob uas muaj tus kab mob, nws yuav tsum tau kho nrog kev daws teeb meem ntawm colloidal sulfur (1%) lossis tooj liab sulfate (80 grams ntawm cov khoom siv rau 1 thoob dej). Yog tias me ntsis ntawm cov xim av daj tau tshwm sim rau ntawm daim nplooj, lawv tau pib nyias thiab thim, qhov no txhais tau tias lub hav txwv yeem muaj kab mob nrog cov nplooj nematode. Hauv qhov no, cuam tshuam thiab rudbeckia raug mob yuav tsum tau muab tshem tawm ntawm lub xaib, thiab cov thaj av ntxiv rau kev tawm tsam yuav tsum tau kho nrog Nemagon, Bazamid lossis Nemafos, thaum ua raws li cov lus qhia uas txuas nrog rau cov tshuaj. Nyob rau hauv qhov kev tshwm sim uas cov nroj tsuag txhua xyoo tau cuam tshuam, tom qab ntawd nrog qhov pib ntawm lub caij nplooj zeeg lub sijhawm tag nrho lawv cov seem yuav xav tau rhuav pov tseg, thaum lub chaw tau muab khawb thiab txau nrog kev daws ntawm manganese potassium, uas yuav tsum muaj zog heev.
Ntawm cov kab tsuag ntawm xws li lub paj, kab ntsig thiab cov viav vias yog qhov txaus ntshai. Tab sis nws yuav tsum nco ntsoov tias yog tias tus rudbeckia tau saib xyuas zoo, tom qab ntawd koj yuav tsis muaj teeb meem dab tsi nrog nws cov kev sau qoob loo, txij li cov nroj tsuag muaj qhov tsis kam tiv taus cov kab mob thiab cov kab tsuag.
Tom qab tawg
Kev Sau Cov Noob
Qhov kawg ntawm kev tawg paj thiab cov noob ripening tshwm sim nyob rau lub caij nplooj zeeg. Kev sau cov noob yuav tsum tau nqa tawm tsuas yog tom qab lawv tau qhuav zoo ntawm cov nroj tsuag nws tus kheej. Tom qab ntawd koj yuav tsum hnav hnab looj tes vaj thiab ua tib zoo sau lawv tshwj tsis yog los ntawm qhov chaw nruab nrab ntawm lub paj. Tom qab ntawd cov noob tau tawg ntawm daim ntawv xov xwm thiab muab tso rau hauv chav zoo ua kom muaj cua.
Perennial caij ntuj no
Nyob rau lub caij nplooj zeeg, nws yuav tsim nyog los luas lub sim saum nruab ntug ntawm cov tsaj ntev mus rau saum npoo av. Xws li cov nroj tsuag yuav tsum tau them rau lub caij ntuj no. Txhawm rau ua qhov no, lub xaib yog them nrog tuab txheej (ntawm 5 txog 7 centimeters) ntawm humus lossis npog nroj tsuag nrog cov nyom qhuav, lossis koj tuaj yeem siv lapnik.

Echinacea lossis rudbeckia
Kev kho kom zoo nkauj ntawm echinacea tau paub ntev. Qhov kom zoo siab, hauv 1753, paj yeeb cov txiv kab ntxwv Carl Linnaeus tau muab rau lub genus Rudbeckia. Lub teb chaws ntawm tag nrho ob qho nroj tsuag yog North American prairie, nyob hauv cov teb chaws Es Xias yav qab teb, thaum lawv nyiam cog qoob loo uas muaj dej noo hauv qhov av ntau heev. Tab sis Mench, uas yog German botanist, nyob rau xyoo 1794 coj echinacea purpurea, uas txog tam sim no hu ua rudbeckia purpurea, mus rau hauv ib tus kheej dua lwm qhov.
Dab tsi yog qhov sib txawv ntawm cov xim no? Piv txwv li, lawv muaj cov xim sib txawv ntawm inflorescences, yog li, hauv Rudbeckia, cov paj ntoo reed tuaj yeem muaj cov duab sib txawv ntawm cov xim daj, xim av thiab txiv kab ntxwv, thiab hauv Echinacea lawv yog raspberry lossis ntshav. Echinacea muaj cov tawv tawv, zoo nkauj, prickly, zoo li khoob khoob bracts thiab muaj khoom, thiab hauv rudbeckia lawv muag muag. Qhov tshwj xeeb no tuaj yeem raug tshawb nrhiav hauv lub npe ntawm Echinocia - "echitnos", uas los ntawm Greek txhais tau tias "prickly". Echinacea tseem tseem qhov txawv los ntawm qhov tseeb tias nws muaj cov khoom siv tshuaj, uas, txawm hais tias muaj kev lees paub ntawm qee tus neeg, ua rau tsis tuaj kiag li hauv rudbeckia.
