Feem ntau, lawv coexist nrog ib hom dej noo-hlub dub ntau yam ntawm poplar, elm, alder, tamarisk, tab sis yuav tso tau nyob ib leeg.
Av, av noo
Fertile, moist, lub teeb substrates nrog kua zoo thiab nruab nrab acidity yog ib qho chaw zoo tshaj plaws rau unpretentious cuav dawb poplar. Tab sis nyob rau hauv qhov tsis ua li cas ntawm xws li ib tug zoo, cov nroj tsuag muaj peev xwm nrog me ntsis acid thiab alkaline xau, nyiaj ntev arid sandstones, hnyav loams, thiab txawm yuav pom kev loj hlob ntawm silt thiab rubble.
Nws tseem ceeb heev! Tsob ntoo yog heev nkag siab rau pruning.Tus cog tag nrho txaus siab rau cov dej ntws nyob ze thiab pas dej los yog av. Ntxiv mus, hauv paus system tsis raug kev txom nyem los ntawm lub caij nyoog dej nyab txhua. Tab sis lub drought siab tev taus ntawm tsob ntoo yog nruab nrab.
Cov Teeb Kom Ua Raws Cai
Tej zaum qhov no tsuas yog qhov kev mob categorical uas tseem ceeb heev hnub-hlub ntoo. Nws nyiam ntau ultraviolet teeb thiab xav tau nws. Nws muaj peev xwm hloov mus rau lub penumbra, tab sis nyob rau hauv xws li tej yam kev mob nws txoj kev loj hlob yuav qeeb. Txawm hais tias, judging los ntawm qhov loj ntawm lub poplar, tus duab ntxoov ntxoo tsis hem nws.
Frost tsis kam
Botanists ua kev zoo siab tsis kam ntawm cov nroj tsuag kom tsawg. Nws tau yooj yim overwinter ntawm -30 ° C.
Spruce, birch, larch, Sib tshooj cedar pine, aspen, juniper, willow, elm thiab Oak, zoo li dawb poplar, ntoo-resistant ntoo uas muaj lub peev xwm tso siab luv frosts.
Yug me nyuam
Yog xav tau ib qho tshiab cog seedling yog yooj yim heev. Nyob rau hauv chaw kub thiab muaj xyoob ntoo, qhov txheej txheem no yog ua tau los ntawm cov noob txoj kev, thiab nyob rau hauv temperate climatic aav, vegetative reproduction ntawm silver poplar yog ntau dua. Nws yog nqa los ntawm grafting los yog sib cais ntawm paus kev loj hlob. Peb yuav to taub cov subtleties hauv ntau yam.
Nws tseem ceeb heev! Poplar noob poob lawv cov txiaj ntsim tom qab ib xyoos. Qhov zoo tshaj plaws tej yam kev mob rau lawv cia yog txias thiab tsawg humidity.Yog hais tias koj nyiam botanical thwmsim thiab yog ib tus neeg mob thiab tus neeg zoo, ces koj tuaj yeem siv sij hawm nrog cog noob. Tab sis cia li npaj kom zoo tshaj plaws germination los ntawm lawv sai li sai tau tom qab sau. Nws yog ces hais tias koj yuav tsum tau sau peat pots thiab nqa tawm sowing.
Qhov no yog ua nyob rau hauv ntub substrate. Thaum sowing noob nyob sab nraum zoov, ib lub txaj yog ntshaw, yam tsis tau tos rau tua, yuav tsum tau them nrog ib tug nyias txheej ntawm straw mulch. Cov khoom yuav khaws cov dej noo thiab tiv thaiv lub lis ntawm huab cua thiab leaching los nag.
