Obdobie po \u201ezamrznut\u00fdch\u201c je pre pestovate\u013eov paradajok najd\u00f4le\u017eitej\u0161\u00edm t\u00fd\u017ed\u0148om roka. Priesady id\u00fa definit\u00edvne do vo\u013enej p\u00f4dy a na internetov\u00fdch f\u00f3rach sa sp\u00fa\u0161\u0165aj\u00fa debaty o tom, ako im zabezpe\u010di\u0165 ten najlep\u0161\u00ed \u0161tart. Medzi star\u00fdmi z\u00e1hradk\u00e1rskymi radami sa \u010dasto objavuje bizarn\u00e1 praktika: hodi\u0165 na dno v\u00fdsadbovej jamy nieko\u013eko hrdzav\u00fdch klincov. Pre\u010do tento trik re\u00e1lne funguje a \u010do na\u0148 hovor\u00ed veda?<\/p>\n

\t\t\t\t\tGal\u00e9ria
\nPre\u010do paradajka potrebuje \u017eelezo?<\/p>\n

\u017delezo (Fe) patr\u00ed medzi esenci\u00e1lne mikroelementy, bez ktor\u00fdch paradajka nedok\u00e1\u017ee pre\u017ei\u0165. Hoci ho rastlina nespotreb\u00fava v tak\u00fdch mno\u017estv\u00e1ch ako dus\u00edk alebo drasl\u00edk, jeho \u00faloha je kritick\u00e1.<\/p>\n

\u017delezo je k\u013e\u00fa\u010dov\u00fdm katalyz\u00e1torom pri tvorbe zelen\u00e9ho listov\u00e9ho farbiva. Bez neho rastlina nedok\u00e1\u017ee efekt\u00edvne viaza\u0165 slne\u010dn\u00fa energiu. Je s\u00fa\u010das\u0165ou enz\u00fdmov, ktor\u00e9 riadia prenos energie a d\u00fdchacie procesy v bunk\u00e1ch rastliny.<\/p>\n

Ak m\u00e1 raj\u010diak nedostatok \u017eeleza, prejav\u00ed sa to takzvanou \u017eelezom vyvolanou chlor\u00f3zou. Listy za\u010dn\u00fa od vrchu \u017eltn\u00fa\u0165, pri\u010dom \u017eilnatina zost\u00e1va s\u00fdtozelen\u00e1. Rastlina chradne, slabne a \u00faroda je minim\u00e1lna.<\/p>\n

\nAko funguje hrdzav\u00fd klinec?<\/p>\n

Fundovan\u00fd z\u00e1hradk\u00e1r mo\u017eno teraz namietne, \u017ee \u010dist\u00e9 \u017eelezo alebo \u010dist\u00e1 hrdza (oxid \u017eelezit\u00fd) s\u00fa pre rastlinu v podstate nerozpustn\u00e9 a nevstrebate\u013en\u00e9. A m\u00e1 absol\u00fatnu pravdu. Rastliny dok\u00e1\u017eu prija\u0165 \u017eelezo z p\u00f4dy len vo forme rozpustn\u00fdch i\u00f3nov, prim\u00e1rne ako dvojmocn\u00e9 \u017eelezo.<\/p>\n

Vedeck\u00e1 biblia o v\u00fd\u017eive rastl\u00edn (Marschner\u2019s Mineral Nutrition of Higher Plants) uv\u00e1dza paradajku ako u\u010debnicov\u00fd pr\u00edklad rastliny, ktor\u00e1 si pri nedostatku \u017eeleza dok\u00e1\u017ee sama okysli\u0165 p\u00f4du okolo kore\u0148ov, aby z nej dok\u00e1zala rozpusti\u0165 a vytiahnu\u0165 aj pevne viazan\u00e9 formy tohto prvku.<\/p>\n

Ako teda klinec pom\u00f4\u017ee?<\/p>\n

Ke\u010f zakopete klinec do p\u00f4dy k paradajke, p\u00f4dna vlhkos\u0165 a kysl\u00edk na\u0161tartuj\u00fa kor\u00f3ziu. Klinec za\u010dne hrdzavie\u0165. Korene paradajky nie s\u00fa pas\u00edvne. Aby kore\u0148ov\u00fd syst\u00e9m dok\u00e1zal \u010derpa\u0165 \u017eiviny, vylu\u010duje do svojho okolia takzvan\u00e9 exud\u00e1ty \u2013 slab\u00e9 organick\u00e9 kyseliny (napr\u00edklad kyselinu citr\u00f3nov\u00fa alebo jabl\u010dn\u00fa) a takzvan\u00e9 siderof\u00f3ry. Tieto pr\u00edrodn\u00e9 kyseliny za\u010dn\u00fa hrdzu z klinca pomaly lepta\u0165 a premie\u0148a\u0165 ju na chel\u00e1ty \u017eeleza. A to je presne t\u00e1 forma, ktor\u00fa kore\u0148ov\u00fd syst\u00e9m paradajky dok\u00e1\u017ee bez probl\u00e9mov nasa\u0165 a transportova\u0165 do listov.<\/p>\n

Ide o prirodzen\u00fd, pomal\u00fd d\u00e1vkova\u010d \u017eeleza, ktor\u00fd funguje po\u010das celej sez\u00f3ny.<\/p>\n

Ako na to<\/p>\n

Ak chcete tento trik vysk\u00fa\u0161a\u0165, neurobte chyby, ktor\u00e9 by priesad\u00e1m ubl\u00ed\u017eili. Pou\u017eite len \u010dist\u00e9 a star\u00e9 klince (v\u00fdhradne klasick\u00e9, \u201e\u010dierne\u201c \u017eelezn\u00e9 klince, ktor\u00e9 u\u017e maj\u00fa hrdzu). Nikdy nepou\u017e\u00edvajte klince pozinkovan\u00e9 alebo nerezov\u00e9! Zinok by mohol vo vy\u0161\u0161ej koncentr\u00e1cii p\u00f4sobi\u0165 toxicky a nerez sa v p\u00f4de nerozlo\u017e\u00ed.<\/p>\n

Klince neh\u00e1d\u017ete priamo pod jemn\u00e9 korene priesady. Vykopte jamu o 10 cm hlb\u0161iu, na dno ho\u010fte 3 a\u017e 5 klincov, zasypte ich vrstvou kompostu alebo zeminy a a\u017e na t\u00fato \u201epriehradku\u201c vysa\u010fte paradajku. Korene si k \u017eelezu dorast\u00fa sam\u00e9, ke\u010f zosilnej\u00fa.<\/p>\n

\n\u010co prida\u0165 do jamky pre stopercentn\u00fd v\u00fdsledok?<\/p>\n

Ak chcete trik s klincami dotiahnu\u0165 k dokonalosti, pridajte k nim ly\u017eicu drevn\u00e9ho popola. Dod\u00e1 potrebn\u00fd drasl\u00edk a v\u00e1pnik, ktor\u00fd chr\u00e1ni plody pred hnilobou \u0161pi\u010diek. M\u00f4\u017eete prida\u0165 aj hrs\u0165 su\u0161en\u00fdch vaje\u010dn\u00fdch \u0161krup\u00edn ako pomal\u00fd zdroj v\u00e1pnika, ktor\u00fd stabilizuje bunkov\u00fa stenu raj\u010diaka.<\/p>\n
