Pertr\u0119\u0161tos petunijos da\u017enai auga labai ve\u0161liai, bet \u017eydi menkai: formuoja daug \u016bgli\u0173 ir tamsiai \u017eali\u0173 lap\u0173, o \u017eiedpumpuri\u0173 ma\u017e\u0117ja. Taip da\u017eniausiai nutinka, kai naudojama per daug universali\u0173 tr\u0105\u0161\u0173 arba vyrauja azotas, skatinantis lapij\u0105, o ne \u017eyd\u0117jim\u0105.<\/p>\n
Kitas ai\u0161kus signalas \u2013 vadinamasis tr\u0105\u0161\u0173 nudeginimas, kai lap\u0173 kra\u0161tai gelsta, ruduoja arba d\u017ei\u016bsta, o v\u0117liau lapai ima kristi. Tai susij\u0119 su substrato druskingumo did\u0117jimu: \u0161aknims tampa sunku pasisavinti vanden\u012f, net jei \u017eem\u0117 atrodo dr\u0117gna, tod\u0117l augalas patiria fiziologin\u0119 sausr\u0105.<\/p>\n
Ilgiau u\u017esit\u0119s\u0119s pertr\u0119\u0161imas silpnina augalo audinius, tod\u0117l petunijos tampa jautresn\u0117s ligoms, kenk\u0117jams ir mechaniniams pa\u017eeidimams. Kra\u0161tutiniais atvejais, ypa\u010d vazonuose, pa\u017eeid\u017eiama \u0161akn\u0173 sistema ir augalas gali nunykti.<\/p>\n
Pirmas \u017eingsnis \u2013 nedelsiant sustabdyti tr\u0119\u0161im\u0105 ir \u012fvertinti situacij\u0105: ar augalas auga vazone, ar grunte. Vazonuose problema pasirei\u0161kia grei\u010diau, nes druskos kaupiasi ribotame substrato kiekyje.<\/p>\n
Jei petunija auga vazone, pravartu nuimti vir\u0161utin\u012f substrato sluoksn\u012f ir augal\u0105 pastatyti ten, kur vanduo gal\u0117t\u0173 laisvai i\u0161b\u0117gti per drena\u017eo angas. Tuomet \u017eem\u0119 reik\u0117t\u0173 gausiai praplauti vandeniu taip, kad jis kelis kartus pertek\u0117t\u0173 per vazon\u0105, stengiantis ne\u0161lapinti lap\u0173 ir \u017eied\u0173.<\/p>\n
Jei petunijos auga grunte, vir\u0161utinio dirvos sluoksnio paprastai nuimti nereikia. Tokiu atveju padeda keli\u0173 minu\u010di\u0173 praplovimas \u0161velnia vandens srove, kad perteklin\u0117s druskos b\u016bt\u0173 i\u0161plautos giliau, o \u0161akn\u0173 zona pama\u017eu stabilizuot\u0173si.<\/p>\n
Pra\u0117jus ma\u017edaug 3 dienoms, verta pa\u0161alinti stipriai pa\u017eeistus, pageltusius ar deformuotus lapus ir \u016bgli\u0173 dalis. Jei b\u016bkl\u0117 neger\u0117ja, o augalas akivaizd\u017eiai silpsta, saugiausia i\u0161eitis \u2013 persodinti \u012f \u0161vie\u017ei\u0105, lengv\u0105 substrat\u0105 su gera drena\u017eo strukt\u016bra.<\/p>\n
Po pertr\u0119\u0161imo petunijoms reikia laiko atsigauti, tod\u0117l tr\u0105\u0161as geriau kuriam laikui atid\u0117ti. Jei buvo naudota \u017eem\u0117 su ilgai veikian\u010diomis tr\u0105\u0161omis, tr\u0119\u0161im\u0105 paprastai verta pristabdyti 3\u20134 savait\u0117ms, o jei sodinta \u012f \u012fprast\u0105 universali\u0105 \u017eem\u0119 \u2013 1\u20132 savait\u0117ms.<\/p>\n
Atsinaujinus tr\u0119\u0161imui, da\u017enai pakanka retesnio ritmo, pavyzd\u017eiui, kas 2\u20133 savaites, stebint augalo reakcij\u0105. Norint skatinti \u017eyd\u0117jim\u0105, verta rinktis tr\u0105\u0161as \u017eydintiems augalams, kuriose daugiau fosforo ir kalio, o azotas n\u0117ra dominuojantis.<\/p>\n
Svarbiausia taisykl\u0117 \u2013 tr\u0105\u0161as naudoti tik pagal gamintojo normas ir netr\u0119\u0161ti \u012f saus\u0105 substrat\u0105. Tr\u0105\u0161as saugiau pilti ant i\u0161 anksto sudr\u0117kintos \u017eem\u0117s, nes taip suma\u017e\u0117ja \u0161akn\u0173 pa\u017eeidimo ir druskingumo \u0161oko rizika.<\/p>\n
\u201eTr\u0105\u0161as visada naudokite ant dr\u0117gnos, i\u0161 anksto palaistytos \u017eem\u0117s \u2013 taip suma\u017einsite \u0161akn\u0173 nudeginimo rizik\u0105\u201c, \u2013 pabr\u0117\u017eia sodininkyst\u0117s specialistai.<\/p>\n","protected":false},"excerpt":{"rendered":"
