Violetinis ar melsvas pomidor\u0173 lap\u0173 atspalvis da\u017eniausiai pasirodo staiga ir neretai i\u0161g\u0105sdina dar\u017eininkus. Vis d\u0117lto toks pakitimas ne visuomet rei\u0161kia lig\u0105 ar kenk\u0117j\u0173 antpl\u016bd\u012f \u2013 da\u017enai tai augalo streso signalas, susij\u0119s su temperat\u016bra ir mityba.<\/p>\n

Pomidorai, patirdami nepalankias s\u0105lygas, gali intensyviau kaupti antocianinus \u2013 nat\u016bralius pigmentus, suteikian\u010dius violetin\u012f atspalv\u012f. Da\u017eniausiai violetavimas matomas lap\u0173 apatin\u0117je pus\u0117je, lapko\u010diuose ar stiebo dalyse, ypa\u010d po keli\u0173 \u0161alt\u0173 nakt\u0173.<\/p>\n

Da\u017eniausia prie\u017eastis \u2013 \u0161altas dirvo\u017eemis<\/h2>\n

Viena tipi\u0161kiausi\u0173 prie\u017eas\u010di\u0173 yra ne pats fosforo tr\u016bkumas dirvoje, o tai, kad atv\u0117sus \u0161akn\u0173 zonai fosforas augalui tampa sunkiai pasisavinamas. Net jei fosforo dirvo\u017eemyje pakanka, \u0161altis pristabdo \u0161akn\u0173 darb\u0105 ir augalas ima rodyti vadinamuosius tr\u016bkumo simptomus.<\/p>\n

Praktikoje tai da\u017eniau nutinka ankstyv\u0105 pavasar\u012f, kai dien\u0105 \u0161il\u010diau, o naktimis temperat\u016bra \u017eenkliai krenta. Pana\u0161i reakcija pasitaiko ir \u0161iltnamiuose, jei dirva dar nesp\u0117jo \u012f\u0161ilti, o laistoma \u0161altu vandeniu.<\/p>\n

K\u0105 patikrinti pirmiausia?<\/h2>\n

Patikimiausias \u017eingsnis \u2013 pamatuoti dirvos temperat\u016br\u0105 ryte, kol jos dar ne\u012f\u0161ild\u0117 saul\u0117. Termometr\u0105 verta \u012fki\u0161ti ma\u017edaug 10\u201315 centimetr\u0173 gylyje netoli \u0161akn\u0173, nes b\u016btent ten sprend\u017eiasi maisto med\u017eiag\u0173 pasisavinimas.<\/p>\n

Jei dirva yra ai\u0161kiai per v\u0117si, skub\u0117ti berti tr\u0105\u0161\u0173 nereik\u0117t\u0173: tai da\u017enai neduoda greito efekto, o perteklinis tr\u0119\u0161imas gali apsunkinti \u0161akn\u0173 zon\u0105. Tokiu atveju svarbiausia stabilizuoti s\u0105lygas, kad \u0161aknys v\u0117l prad\u0117t\u0173 normaliai dirbti.<\/p>\n

Kada \u012ftarti tikr\u0105 fosforo tr\u016bkum\u0105?<\/h2>\n

Jei dirva jau pakankamai \u0161ilta, o violetinis atspalvis nema\u017e\u0117ja ir augalas akivaizd\u017eiai l\u0117\u010diau auga, galima \u012ftarti real\u0173 fosforo stygi\u0173. Papildomai verta \u012fvertinti, ar pomidoras neauga pernelyg susl\u0117gtame, u\u017emirkstan\u010diame substrate \u2013 tokioje dirvoje \u0161aknys ken\u010dia, o mityba blog\u0117ja.<\/p>\n

Esant \u012ftariamam fosforo tr\u016bkumui, da\u017enai pasirenkamas fosforo turintis lapinis tr\u0119\u0161imas, nes per lapus maisto med\u017eiagos pasisavinamos grei\u010diau nei i\u0161 dirvos, ypa\u010d kai s\u0105lygos nestabilios. Pur\u0161kim\u0105 geriausia atlikti ryte arba v\u0117lyv\u0105 popiet\u0119, laikantis etiket\u0117s norm\u0173 ir nedidinant tirpalo koncentracijos.<\/p>\n

Svarbu suprasti, kad senesni lapai ne visada gr\u012f\u017eta \u012f visi\u0161kai vienod\u0105 \u017eali\u0105 spalv\u0105. Tiksliausias rodiklis \u2013 nauji lapai ir bendras augimo tempas: jei nauji \u016bgliai sveiki, o violetavimas neplinta, priemon\u0117s grei\u010diausiai suveik\u0117.<\/p>\n","protected":false},"excerpt":{"rendered":"
