Ngokuwa, amahlathi agqithisileyo adla ngokuphelelwa ngamagqabi. Amaqondo obushushu asezantsi ayabanyanzela ukuba baye kuphumla, kuba kungenjalo ngekhe baphile. Nangona kunjalo, Kukho uhlobo lwesityalo, nangona sithathwa njengesinqumlayo, sinophawu olwenza ukuba imbonakalo yomhlaba othile ibonakale, kulungile, yahlukile.
Yinto eyaziwa ngokuba yi-marcescente, kwaye asiyifumani emahlathini kuphela, kodwa inokuthi ikhule nakweyiphi na indawo apho kukho intwasahlobo, ihlobo, ukwindla nasebusika, kwaye amaxesha amane onyaka ahlukile omnye komnye.
Zithini iimpawu zesityalo seMarcescente?
Kwisityalo esinqabileyo, masithi siqhelekile, ukufika kokwindla kuphawula ukuqala kokuphela kokutya kwamagqabi. Ngamanye amagama, njengokuba imozulu iyaphola kwaye iqabaka yokuqala iqala ukubhalisa, umthi okanye ityholwana liyakuphuma ngamagqabi, anokutshintsha umbala (ukusuka kuluhlaza, tyheli, orenji okanye bomvu, kuxhomekeke kuhlobo) njengoko uphela. izondlo.
Xa sele yomile kwaphela, oko kukuthi, wakube umdaka kunye nepetiole (isiqu esidibanisa nesebe) nayo ilahlekelwa bubomi, umoya uya kuyikhathalela ukuyivumela iwele emhlabeni. Ukuba le ndawo ayicocwanga (into ethi ngendlela esingayicebisi ukuyenzela into esiza kuphawula ngayo ngoku), entwasahlobo isityalo siyakwazi ukubuyisa inxenye yezakhamzimba ebizisebenzisa ukuvelisa loo magqabi.
Kodwa oku, njengoko sisitsho, kwenzeka ntoni kwiintlobo eziqhelekileyo ezinqabileyo, ezinjengezo zohlobo Acer (iimaphu) umzekelo. Kodwa oku akunjalo kuzo zonke iimeko.
Kukho uhlobo lwesityalo, i-marcescente, ethi xa kubanda, ewe, ayeke ukunika amagqabi izondlo, kodwa xa zomile, zihlala emasebeni, zihlala zide ziphume kwakamsinya nje ukuba imozulu iphucuke. Kungenxa yokuba i-petiole ihlala iphila, okanye ubuncinci ixesha elide ngokwaneleyo ukuze loo mthi okanye isihlahla singaphumi emagqabini.
Ngokombono wethu, ayiqhelekanga intle. Kusengqiqweni ke oko, ingakumbi ukuba sizinikele kwizityalo ezikhulayo. Igqabi elomileyo lihlala lifana nengxaki, okanye ukufa kweso sivuno. Kodwa imarcescente isibonisa ukuba inokuba ntle, kwaye iluncedo.
Izibonelelo zezityalo zemarcescent
Ngaba sikhona isibonelelo sokugcina amagqabi omile ebusika? Nabani na onokucinga ukuba yinkcitha-xesha yamandla, kunye nokuchitha ixesha kuba, okukhona bethatha ixesha elide ukuwa, kokukhona kuya kuthatha ixesha elide ukuba isityalo sibe nezakhamzimba eziza kukhutshwa msinyane nje ukuba zibole.
Kodwa kwakhona, ubukumkani bezityalo buyasimangalisa.
Njengoko sisazi, zininzi izilwanyana ezitya uhlaza, kwaye kuzo, zininzi ezinye ezondla emasebeni, njengexhama okanye ielk. Kuba, Ngokugcina la magqabi, omile kwaye kungoko angekho mnandi njengoko enencasa engathandekiyo, ayakhuselwa. Kodwa kusekho okungakumbi.
Kwiindawo ezineentaba zeetropiki, ngakumbi kwiindawo eziphakamileyo, kukho ezinye iintlobo ezisebenzisa amagqabi ukuzikhusela engqeleninjenge U-Espeletia schultzii. Esi sisityalo esikhula ngokukhawuleza esikhula endle kwiiAndes zaseColombia, e-Ecuador naseVenezuela, kwindawo ephakame kangangeemitha ezingama-4300 ngaphezulu komphakamo wolwandle.
Ngexesha lentwasahlobo nasehlotyeni ikhula ngaphandle kwengxaki, kodwa xa kufika ubusika iyayeka ukukhula. Amagqabi awomileyo eminye iminyaka ayagcinwa, ekhusela isiqu. Ngale ndlela, inokuhluma ngaphandle komzamo omkhulu xa iimeko ziphucuka.
El ISenecio keniodendron lolunye uhlobo esinokuthi siqwalasele i-marcescente. Ixhaphakile kwiNtaba yaseKenya, apho ikhula khona phakathi kweemitha ezingama-3900 kunye ne-4500 ngaphezulu komphakamo wolwandle. Emini kushushu kakhulu kangangokuba amaqondo obushushu angadlula kuma-40ºC; hayi ngelize, zikufutshane neikhweyitha, kodwa ebusika loo maqondo obushushu ehla kwaye anokwehla aye -30ºC. Ukuphila, into eyenzayo kukugcina amagqabi omile ixesha elide kangangoko kunokwenzeka, ukukhusela umboko.; kwaye ukongeza, i-rosette yamagqabi aluhlaza ivala ebusuku, igcina isikhokelo sokukhula sikhuselekile.
Zininzi iintlobo zezityalo zemarcescent
Sithethile malunga nezinye iintlobo, kodwa ... ngaba sinayo nayiphi na eYurophu kunye / okanye naseMelika engumkhenkce? Ngapha koko, ayisiyiyo enye kuphela, kodwa uninzi. Njengokuba, zonke ICarpinus (uphondo), UQuercus (oki), kunye Fagus (Uhlobo lwe-beech) zi. Benza amahlathi ethu abonakale emdaka ebusika. Emva koko kuphuma amagqabi aluhlaza, endaweni yawo omileyo.
Ezi zintathu ziziganeko ezibonakaliswa ngokuba yimithi emikhulu, enezithsaba ezixineneyo. Kuqhelekile ukuba badlule kwi-20 yeemitha ukuphakama, kwaye inqanaba lokukhula kwabo liyacotha. Zisetyenziswa kakhulu kwizitiya logama nje imozulu ithambile kwaye kukho iqabaka. Ngokunjalo, bafuna umhlaba one-pH ene-asidi, etyebile kwizinto eziphilayo, enzulu kunye nomsele olungileyo.
