Izitshalo zihlala zinamandla okusimangaza. Sicabanga ukuthi siyabazi, kodwa iqiniso ukuthi kuningi okusamele kutholakale. Noma ngabe beziphatha ngendlela elindelekile, bangakudlula esikulindele. Yilokho nje okwenzeka kuye pando, esinye sezidalwa ezindala kunazo zonke nezisindayo kunazo zonke emhlabeni: kulinganiselwa ukuthi, awunasisindo esingaphansi noma esingaphansi kwamathani angama-6615.
Yisihlahla esaziwa nge-aspen, esivame kakhulu eNyakatho Melika. Lokhu kunamandla okuphindaphindeka ngokwe-asexually, okungukuthi, ngezindlela imbewu engadingekile ngazo, kepha kungaba ngokukhiqiza amahlumela empande, noma ngokusika. Endabeni yepando, Inhlanhla kubonakala sengathi imomotheka ohlelweni lwayo lwempande: kulinganiselwa ukuthi icishe ibe neminyaka engama-80.000 ubudala.
Uyini umlando wepando?
Umlando wepando awukacaci. Kucatshangwa ukuthi bekufanele ikhule ezimeni ezihamba phambili, okuyizimo zayo imililo ejwayelekile, nezimo zezulu ezilandela iphethini yemvelo enomswakama iye endaweni eyomile kakhulu. Ngakolunye uhlangothi, umlilo uvimbele ama-conifers, imbangi yawo enkulu, ukuthi ande; futhi ngakolunye uhlangothi, ukushintshashintsha kwezimvula ezivamile nesomiso kuvimbele imbewu yabo ukuthi ifinyelele ethekwini elihle kanye nemipopula esemncane ukuthi ingasinda.
Umbuzo ongase uzibuze wona uwukuthi: ukwazile kanjani ukudlula ngemuva komlilo? Ngenxa yezimpande zawo, okuthi lapho zikhula ngaphansi komhlaba, zivikelwe. Ngakho-ke, uhlelo lwayo lwempande lungaziqhenya ngokuba mdala emhlabeni: iminyaka engama-80.000 ubudala.
Namuhla imililo ifana nokufa, inhlekelele engokwemvelo, futhi ngesizathu esizwakalayo: iningi kakhulu libangelwa ngabantu abafuna ukuhlanganisa lezi zindawo eziluhlaza. Kepha kufanele sikugcine engqondweni lokho imililo yehlathi lemvelo, okungukuthi, leyo engadalwanga yisintu, kepha kunalokho yisimo sezulu sendawo, iyingxenye yalezi zinhlelo zemvelo.
Ngizophuma kancane manje endabeni, kepha ngokwesibonelo amahlathi e-eucalyptus ase-Australia adinga imililo ngezikhathi ezithile - ngiyasho, ezemvelo - ngoba uma kungenjalo izibonelo zingakhula futhi zikhule, kanti abasha bebengeke ithuba lokuphila. Ngokuhamba kwesikhathi, lelo hlathi lalizofa. Futhi lokho akushiwo izitshalo ezithile zase-Afrika esizithandayo namuhla, njenge eProtea. Imbewu yalezi zihlahlana ezikhiqiza izimbali ezimangazayo ingahluma kuphela ngemuva kokufakwa emazingeni okushisa aphezulu.
Njengoba ukwazi ukubona, imililo ibalulekile ezifundeni ezithile. Ngakho-ke, izitshalo ezifana nepando zingathathwa njengenhlanhla.
Ziziphi izici zayo?
Yize uma usibona esithombeni kungabonakala sengathi kunezinhlobo eziningi ze-aspen ezikhula ndawonye, empeleni zonke zivela ohlelweni olufanayo lwezimpande, okusho ukuthi zonke ziyafana. Leli koloni lama-clones ithatha indawo engamahektha angama-43 futhi yakhiwe ngeziqu ezingaba ngu-47.000. Isikhathi sokuphila ngasinye salezi ziqu cishe iminyaka eyi-130.
Into ethakazelisa kakhulu ukuthi isiqu ngasinye noma isiqu singakhiqiza izimpande ezisemaceleni ukukhuthaza ukukhula kweziqu ezintsha, lapho, i-pando inganweba kakhudlwana uma izimo zilungile.
Ngabe kwake kwageleza?

Sithe i-pando iyikho ngenxa yokukhiqizwa kwamahlumela ezimpande, kepha ... ngabe yake yachuma? Izitshalo eziningi ziyaphindaphindeka, ngaphezu kwakho konke, ngezimbewu, njengoba kuyindlela ephumelela kunazo zonke yokuqinisekisa ukuthi lezi zinhlobo ziyaphila, kepha kwenzekani ngezihlahla ezingakhiwa ngokwemvelo?
Impendulo ilula njengoba inzima: ipando liyakuqhakaza futhi likhiqize imbewu, kepha yilabo abaseduze namachibi noma nemithombo kuphela abayosinda, noma kugxilwe ezindaweni ezinezindawo ezidonsela kuzo noma kwezinye izindawo ezibonisa ukuma komhlaba.
Njengokulangazelela, ukusho ukuthi kukhona amanye amaqembu ezihlahla ze-aspen ezisentshonalanga yeNyakatho Melika ezingakaze zihlume okungenani iminyaka eyi-10.000 XNUMX, kusukela eminyakeni yokugcina yeqhwa.
Sitholakalaphi isihlahla sepando?
Uma ufuna ukuyobona lokho okubhekwe njengenye yezimangaliso ezingama-40 zaseMelika, kufanele uvakashele i- ithafa lesiziba sezinhlanzi, entshonalanga eyedlulele ye-Colorado Plateau, esifundazweni sase-Utah, e-United States. Ungakhohlwa ikhamera yakho kanye / noma iselula yakho, ngoba ubuhle bale ndawo buyamangalisa 😉.
Izici ze-Aspen
I-pando ingeyenhlobo I-Populus tremuloides, okungukuthi, i-aspen yaseMelika (eYurophu sine- I-Populus tremula, eyaziwa nangokuthi i-aspen). Kungumuthi onqabile odabuka eNyakatho Melika, ofinyelela kude enyakatho neCanada.
Ingafinyelela ubude obufinyelela kumamitha ayi-25, nesiqu esiphakathi kuka-20 nobude obungamasentimitha ayi-140 ububanzi. Amaqabunga acishe abe yindilinga, nosayizi ka-4 kuye ku-8 cm ububanzi, aluhlaza ngombala ngaphandle kwekwindla lapho eba phuzi.
Ikhiqiza izimbali kuma-catkins ngesikhathi sentwasahlobo, futhi angaba ngowesifazane noma owesilisa. Izithelo ziyi-capsule eyi-1cm ubude, kanti kuyo ngayinye kunezinhlamvu eziyi-10 ezine-cottony fluff enamathiselwe ezisiza ukuthi zihlakazeke kalula ngosizo lomoya.
Kuyinto isitshalo ukuthi imelana namazinga okushisa aphakeme kakhulu, kanye nesithwathwa esikhulu. Ngaphezu kwalokho, kubekezelela ukuthena, yingakho kuvame ukusetshenziswa njengothango oluphakeme.
