Juodos, \u012fdubusios d\u0117m\u0117s pomidor\u0173 apa\u010dioje da\u017enai i\u0161g\u0105sdina net patyrusius dar\u017eininkus, ta\u010diau daugeliu atvej\u0173 tai n\u0117ra infekcin\u0117 liga. Da\u017eniausiai kaltas fiziologinis sutrikimas, susij\u0119s ne su grybais ar bakterijomis, o su augalo mityba ir vandens re\u017eimu.<\/p>\n

Toks pa\u017eeidimas vadinamas pomidor\u0173 vir\u0161\u016bniniu puviniu. I\u0161 prad\u017ei\u0173 vaisiaus gale atsiranda vandeningas ar \u0161viesiai rusvas plotelis, v\u0117liau jis tams\u0117ja, kiet\u0117ja ir did\u0117ja. V\u0117liau \u012f pa\u017eeist\u0105 audin\u012f gali patekti mikroorganizmai, tod\u0117l pomidoras ima grei\u010diau p\u016bti.<\/p>\n

Kas i\u0161 ties\u0173 sukelia d\u0117mes?<\/h2>\n

Pagrindin\u0117 prie\u017eastis da\u017eniausiai yra sutrik\u0119s kalcio patekimas \u012f spar\u010diai augan\u010dius vaisius. Svarbu tai, kad problema da\u017enai kyla net tada, kai dirvoje kalcio pakanka, ta\u010diau augalas jo nesp\u0117ja \u201eatgabenti\u201c iki vaisi\u0173 d\u0117l netolygaus dr\u0117gm\u0117s re\u017eimo.<\/p>\n

Da\u017enas scenarijus toks: kelias dienas dirva perd\u017ei\u016bsta, o po to augalai gausiai palaistomi. Staig\u016bs dr\u0117gm\u0117s \u0161uoliai trikdo vandens jud\u0117jim\u0105 augale, o kartu ir kalcio perna\u0161\u0105, tod\u0117l pirmieji vaisiai tampa labiausiai pa\u017eeid\u017eiami.<\/p>\n

Kada rizika did\u017eiausia?<\/h2>\n

Vir\u0161\u016bninis puvinys da\u017eniausiai i\u0161ry\u0161k\u0117ja vasaros viduryje, kai kar\u0161ta ir dirva greitai netenka dr\u0117gm\u0117s. Didesn\u0117 rizika b\u016bna pomidorus auginant \u0161iltnamyje ar vazonuose, nes ten substratas d\u017ei\u016bsta spar\u010diau nei atvirame grunte.<\/p>\n

Da\u017eniau nuken\u010dia ir veisl\u0117s su pailgais vaisiais, pavyzd\u017eiui, slyviniai pomidorai. D\u0117m\u0117s da\u017eniausiai pasirodo ant pirm\u0173j\u0173 deran\u010di\u0173 vaisi\u0173, ta\u010diau nepalankiomis s\u0105lygomis problema gali kartotis vis\u0105 sezon\u0105.<\/p>\n

K\u0105 daryti, kad neplist\u0173?<\/h2>\n

Pa\u017eeistos d\u0117m\u0117s neatsistato, tod\u0117l labiausiai apgadintus vaisius verta pa\u0161alinti, kad augalas energij\u0105 skirt\u0173 naujiems. Svarbiausias \u017eingsnis yra pastovus laistymas ma\u017eesn\u0117mis normomis, kad dirvos dr\u0117gm\u0117 b\u016bt\u0173 kuo tolygesn\u0117, ypa\u010d per kar\u0161\u010dius.<\/p>\n

Padeda ir dirvos mul\u010diavimas, nes jis suma\u017eina vandens garavim\u0105 ir staigius dr\u0117gm\u0117s svyravimus. Taip pat verta vengti perteklini\u0173 azoto tr\u0105\u0161\u0173, kurios skatina labai spart\u0173 augim\u0105, ir atsargiai dirbti prie \u0161akn\u0173, kad j\u0173 nepa\u017eeistum\u0117te.<\/p>\n

Jei situacija kartojasi, verta \u012fvertinti dirvos reakcij\u0105 ir druskingum\u0105, nes netinkamas pH ar didesnis u\u017edrusk\u0117jimas apsunkina maisto med\u017eiag\u0173 pasisavinim\u0105. Vien tik kalcio pur\u0161kimai ant lap\u0173 ar vaisi\u0173 da\u017enai nei\u0161sprend\u017eia problemos, nes esm\u0117 paprastai yra ne kalcio tr\u016bkumas dirvoje, o jo perna\u0161os sutrikimai augale.<\/p>\n","protected":false},"excerpt":{"rendered":"
