Ptelea (lat. Ptelea) - genus ntawm cov ntoo txiav ntoo thiab cov ntoo loj hlob ntawm tsev neeg Rutovye. Lwm lub npe yog elm lossis tawv tsho. Lub genus suav nrog 10 hom. Ntuj ntau - North America thiab Mexico. Pteleia yog tsob ntoo zib ntab zoo nkauj; nws kuj tseem muaj txiaj ntsig zoo rau nws cov khoom zoo nkauj.
Yam ntxwv ntawm kab lis kev cai
Pteley yog tsob ntoo lossis tsob ntoo siab txog 6-8 m siab nrog cov yas nyias nyias thiab cov ceg muaj zog zoo nkauj. Cov tub ntxhais hluas tua yog pubescent, xim av xim av. Cov nplooj yog ntom, ci, hloov pauv, qog, petiolar, muaj cov ntxhiab tsw, suav nrog 3-5 yam tsis muaj ovoid lossis nplooj elliptical-oval.
Cov paj yog cov tsis nyiam poj niam, ntsuab-dawb lossis grey-ntsuab, nrog rau cov ntxhiab tsw tshwj xeeb, sau hauv paniculate inflorescences nyob hauv axils ntawm cov nplooj sab saud thiab ntawm qhov kawg ntawm cov ceg. Lub calyx muaj 4-6 sepals, ntog sai. Cov txiv hmab txiv ntoo yog oblong lionfish, feem ntau yog xim daj, muaj qhov tsw ntxhiab, muaj 2-3 noob.
Pteley yog qhov tiv taus te tiv taus. Hom kab mob uas tiv taus khaub thuas feem ntau suav tias yog peb nplooj nplooj (lat. Eletelea trifoliata), yog li nws tau nthuav dav hauv Urals thiab Siberia. Txawm hais tias qhov tseeb tias tsob ntoo feem ntau khov me ntsis thaum lub caij ntuj sov, lawv nquag tawg paj thiab txi txiv thaum lub caij cog qoob loo.
Ntawm cov ntawv zoo nkauj, ptelei kuj tau sau tseg:
* Pentaphylla - tsob ntoo nrog nplooj uas muaj tsib nplooj;
* Fastigiata - shrubs nrog lub hauv paus pyramidal;
* Glauca - cov nroj tsuag nrog cov nplooj ntsuab ntsuab, pubescent thoob plaws saum npoo.
Lawv tsis muaj qhov ntxim nyiam hauv kev ua vaj zaub: noog serrata (lat. Ptelea serrata) - yog tsob ntoo siab txog 3.5 m siab nrog cov nplooj trifoliate nyuaj; Ptelea ci ntsa iab (lat. Ptelea nitens) yog tsob ntoo siab txog 3 m siab nrog cov xim daj-xim av thiab cov nplooj nyuaj, suav nrog 3-5 rhombic-lanceolate nplooj.
Cov subtleties ntawm kev cog qoob loo thiab luam tawm
Pteleia yog tsob ntoo photophilous uas xav tau teeb pom kev zoo rau kev loj hlob ib txwm muaj thiab kev txhim kho. Yuav lees txais qhov ntxoov ntxoo me ntsis. Fertile, moist, nruab nrab cov av yog qhov zoo dua. Cov ntsev, swampy, cov kua qaub heev yuav tsis haum rau kev coj noj coj ua. Nrog kev yooj yim, tus noog yuav tiv taus lub sijhawm qhuav qhuav thiab tsis muaj dej noo.
Pteley feem ntau nthuav tawm los ntawm cov noob. Kev cog qoob loo tsawg, tsuas yog 10-20%. Noob xav tau kev faib tawm ua ntej hauv 3-4 lub hlis. Kev txiav kuj tseem siv tau, tab sis cov txheej txheem no nthuav tawm ntau qhov teeb meem. Rooting tus nqi ntawm cov noog yog 5-8%. Kev cog cov ptelei cov yub yog nqa tawm thaum lub caij nplooj ntoo hlav, qhov zoo tshaj ntawm cov nroj tsuag yog 2-3 m.
Saib xyuas
Tsis xav tau kev saib xyuas tshwj xeeb rau tus noog. Kev ywg dej kom zoo, cog thiab xoob yog qhov tseem ceeb. Sab saum toj hnav khaub ncaws nrog cov ntxhia thiab cov organic chiv tau txais tos. Pteley zam rau kev rov ua dua tshiab thiab ua kom huv huv yam tsis muaj teeb meem, rov zoo sai.
Pab
Pteleia tau nquag siv hauv kev tsim kho vaj tsev tus kheej thaj av, ob qho tib si hauv kev cog ib leeg thiab hauv kev tsim cov pab pawg zoo nkauj. Thunberg barberry, tshuaj yej hav txwv yeem, Ottawa barberry, qee qhov conifers thiab cov paj ntoo muaj hnub nyoog tuaj yeem yog phooj ywg zoo rau ptelee.
