Lub pinnacle ntawm cov nroj tsuag evolution yog ib tug paub, tab sis tsis muaj tsawg amazing thiab txawv incredibly lub neej daim ntawv - ntoo. Hauv ntau txoj kev ntseeg, tsob ntoo yog lub cim ntawm lub neej, fertility lossis kev paub, thiab hauv cov dab neeg ua haujlwm nws nyob deb ntawm qhov kawg. Leej twg tsis nco qab tsob txiv apples cawm cov me nyuam los ntawm swan geese, los yog epic willow quaj rau cov tub rog Lavxias tuag? Tab sishnub no peb yuav tsis nco qab txog cov dab neeg dab neeg thiab tham txog cov yam ntxwv ntawm daim ntawv no lub neej tshwj xeeb, tsim cov yas, lawv hom thiab ntom.
Krone yam
Dendrologists tau qhia txog qhov ntsuas qhov txawv ntawm cov ntoo. Lawv qhia txog cov ntoo uas ua rau sab saud - txog li 20 meters. Qhov loj ntawm qib thib ob yog los ntawm 10 txog 20 meters, qhov thib peb - 5-10 meters.
Thaum tsim qhov chaw, cov neeg tsim qauv toj roob hauv pes yuav tsum coj mus rau hauv tus account tsis tsuas yog qhov loj, tab sis kuj zoo li lub cev thiab hom yas. Lub crown ntawm tsob ntoo tsis nyob ntawm nws qhov siab ntawm txhua qhov, tab sis nws txiav txim siab qhov zoo. Ib tsob ntoo loj 30-meter thiab tsob ntoo uas tsis ncav cuag ib 'meter' qhov siab tuaj yeem muaj qhov zoo ib yam.
Cov ntaub ntawv hauv qab no ntawm tsob ntoo ntoo yog qhov txawv txav:
• pyramidal (poplar);
• elongated (juniper);
• columnar(kum apple tree);
• umbrella (Italian ntoo thuv);
• spherical, oval (Siberian kua, elm, txiv ntseej, larch);
• quaj (weeping willow, birch);
• longline (pine);
• creeping (cedar elfin, creeping apple species).
Crown Ceev
Ib qho tseem ceeb hauv kev npaj cov chaw ua si thiab lub vaj yog qhov ntom ntawm cov yas. Qhov siab tshaj plaws yog qhov uas qhov khoob yog 25%. 25-50% ntawm qhov khoob tsim ib qho nruab nrab ntom ntom ntom. Yog hais tias lawv nyob ntau tshaj ib nrab, lub crown ntawm tsob ntoo yog lub teeb thiab muag heev. Cov ntoo tuaj yeem ua tau ruaj khov lossis sib cais-compact, qhov twg muaj qhov sib txawv ntawm qib.
elongated shape
Cov duab no yog tus cwj pwm los ntawm cov duab spindle. Nyob rau hauv qhov chaw nws yog ntau voluminous, es nqaim ntawm lub hauv paus thiab elongated upwards. Poplar thiab Provencal cypress yog cov sawv cev ntawm daim ntawv no. Qhov no yog qhov kev xaiv yeej-yeej los tsim cov vaj me me. Tsim cov kab ntsug nruj, lawv cov yas tso tawm qhov tsis sib xws hauv txoj kev zoo tshaj plaws thiab ua rau kom qhov siab ntawm qhov siab.
Txoj ntoo ntawm cov duab no zoo kawg nkaus ua kom muaj sia nyob thiab tsim qhov kev xav nyob deb. Kab ntawm pyramidal poplars cog nyob rau hauv qab ntawm lub hollows tsim ib tug tshwj xeeb spectacle: lub nqaim silhouettes ntawm cov ntoo hais txog cov ntxhab slopes, contrasting nrog lawv. Tsis tas li ntawd, kev cog ntoo zoo li no ua rau muaj cua daj cua dub zoo heev.
Kab duab
daim ntawv no yog ze rau elongated, tab sis nws cov neeg sawv cev tsis muaj thickening nyob rau hauvnruab nrab ntawm lub crown, thiab muaj ib tug dav dav puag, yuav luag txuam qhov loj ntawm lub sab saum toj ntawm tsob ntoo, uas feem ntau muab lub tswv yim ntawm ib kem. Cov chaw ua si lom zem heev nrog cog ntoo ntawm cov duab zoo sib xws, muab rau lawv me ntsis qab qab tsw. Muab cog rau hauv cov qauv checkerboard, cov ntoo columnar muab kev tiv thaiv cua zoo.
Pyramid crown
Qhov ntxim nyiam tshaj plaws ntawm tsob ntoo yog pyramidal. Tsis ntev los no, nws yog kev cai hu rau txhua tsob ntoo nrog lub crown nyob rau hauv cov duab ntawm lub khob hliav qab nrog ib tug pronounced ntom ntim uas tsim ib tug meej geometric silhouette. Cov yas zoo sib xws tuaj yeem sib txawv ntawm ib leeg. Qhov sib txawv no yog txiav txim siab los ntawm kev loj hlob ntawm cov ceg: nce toj-loj hlob ceg tsim ib qho elongated tuab thav duab ntim, kab rov tav - me ntsis monumentality, poob sawv daws yuav muab cov nroj tsuag lush thiab romantic saib.
Tier crown
Cov yas zoo li no ua rau lub tswv yim tias tsob ntoo muaj ntau theem - kab rov tav txheej, yuav luag zoo tib yam hauv ntim. Cov ntoo qub no muaj nyob hauv Lebanese cedars, qee cov nroj tsuag: dogwood, dwarf conifers. Cov neeg tsim qauv niaj hnub siv cov kab hauv qab hauv cov toj roob hauv pes nthuav dav nrog cov kab geometric meej.
Nkauj ntsuag
Cov ceg nyias nyias poob rau hauv av, ilv zoo-groomed tsos. Weeping crown, lees paub, feem ntau kov thiab romantic. No tsob ntoo ntoo, daim duabuas tau nthuav tawm hauv tsab xov xwm, rau tag nrho nws cov kev lom zem, xav tau kev saib xyuas tas li thiab kev saib xyuas zoo. Xws li cov nroj tsuag yog tshwj xeeb tshaj yog zoo nyob ze dej los yog delimited poob.qib. Piv txwv li, ntawm toj roob hauv pes thiab hav tsis sib xws.
Sperical, oval crown
Spherical lossis oval crowns tuaj yeem hloov pauv, flattened, cylindrical, nthuav, thiab lwm yam. Cov neeg sawv cev zoo tshaj plaws ntawm cov ntoo ntawm cov duab no yog beeches, oaks, elms.
Daim ntawv no feem ntau siv rau hauv kev tsim vaj tsev niaj hnub. Creeping hom, raws li txoj cai, yog ntawm Far Eastern keeb kwm. Lawv yog cov kab txawv thiab picturesque: cov nroj tsuag kis raws hauv av, xws li nyob rau hauv tej yam kev mob ntawm ntug hiav txwv dej los yog nyob rau hauv highlands.
Umbrella crown
Txoj kab uas hla ntawm tsob ntoo yog undoubtedly lub kaus. Lub cev du tag nrog lub kaus zoo kawg nkaus. Tag nrho cov ntoo ntawm hom no, los ntawm classic umbrella ntoo thuv mus rau exquisite magnolia - lub kaus nkauj xwb, muaj ib tug monumental tsos. Lub crown ntawm cov duab no tuaj yeem tau txais kev tsim khoom, nrog rau cov cuab yeej tshwj xeeb tiv thaiv cov ceg ntawm qee hom quaj, xws li Sophora, los ntawm kev poob. Cov duab ntawm cov kaus tuaj yeem muaj ntau haiv neeg: domed, ntau dua lossis tsawg taw. Nws tuaj yeem muaj qhov pom tsis pom tseeb.
Kev tsim tsob ntoo ntoo
Yuav luag txhua hom ntoo ntoo loj hlob hauv cov chaw ua si hauv nroog lossis cov vaj tsev yuav tsum tsim kom raug. Qhov no yog tiav los ntawm kev txiav. Ntawm ntau cov txheej txheem tsim cov yas uas twb muaj lawm, txoj kev siv ntau yam yog sparse-kab ntev. Txoj kev pruning no siv tau rau txhua tsob ntoo txiv hmab txiv ntoo thiab cov qoob loo chaw ua si.
Qhov tseem ceeb ntawm txoj kev no yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txiav nws nws yuav tsum muaj 10-12 tsob ntoo, nws raug nquahu kom txiav 10-12 ceg ntawm cov ceg ntoo. seedlings los ntawm lub chaw zov me nyuam twb tau muag nrog ib tug tsim thawj theem ntawm ob peb sab ceg. Ntxiv tsim ntawm lub crown yog nqa tawm raws li cov nroj tsuag loj hlob. Muab hais tias kev loj hlob nyob rau hauv thawj xyoo ntawm tsob ntoo yog me me, lub formative pruning ntawm crown ntawm ntoo yog nqa tawm tsuas yog nyob rau hauv lub caij nplooj ntoos hlav ntawm peb lub xyoos. Lub cev yuav tsum tau txiav ntawm qhov siab ntawmm qhov siab los ntawm qhov pib ntawm thawj theem, tsis txhob hnov qab tawm txog 10 buds rau ntawm nws, los ntawm cov ceg tshiab sab nraud thiab txuas ntxiv tua yuav tshwm sim rau lub caij ntuj sov.
Nyob rau lub caij nplooj ntoos hlav xyoo plaub, los ntawm cov ceg tshiab sprouted, ob peb ntawm cov muaj zog tshaj tawm, teem ib lub voj voog, tshem tawm cov seem. Qhov no yuav yog theem ob ntawm lub crown. Hauv ob xyoos tom ntej no, lawv kuj tsim qhov thib peb ntawm 1-2 ceg. Ntawm qhov siab ntawm 4-4.5 m, kev loj hlob ntawm tsob ntoo yog nres los ntawm truncating lub pob tw saum lub hauv paus ntawm ib tug muaj zog qaum ceg. Kev tsim ntawm cov ntoo ntawm cov ntoo nyob rau theem no yog suav tias yog tiav. Kev pruning kom zoo tso cai rau koj kom tau txais tsob ntoo zoo nkauj, duab thiab saib uas ua rau muaj kev zoo nkauj tiag tiag.
