Ndiyazibuza ukuba kutheni sinoyika kakhulu igama elithi "nitrate"? Kwizenzululwazi, ezi zizaziso ezingenakubungozi ze-nitric acid, izityalo ezithathayo emhlabeni njengento efunekayo yezinto eziphilayo. Imifuno ngaphandle kwe-nitrates kwaye isenzo sabo emzimbeni womntu asikho nje. Ubungakanani obuninzi! Ukuba le nkunkuma ikhula kakhulu kwisityalo (ngenxa yokuchumisa okusebenzayo komhlaba kunye ne-nitrate), imane ibeka ngaphandle kwesitokisi! Nangona kunjalo, i-culprit yecala lokutyhefu kunye nemifuno yasendle ayikho i-nitrates ngokwabo, kodwa i-nitrites eyakhiwe kubo emzimbeni. Ukungena kwegazi, kunokubangela ukuba i-oksijini yindlala, iphazamise umsebenzi wegciwane lesisu, ukwandisa i-oncorrhiza, kwaye ukusetyenziswa kwe-nitrate eyodwa enkulu kubangele ukutyhefuza. Kakade ke, ezi ngxaki zifumaneka kuphela xa zidla ukutya rhoqo kwe-nitrate. Nangona kunjalo, kunikezelwa ukuba akunakwenzeka ukucacisa inani le "chemistry" kwimifuno okanye kwisiqhamo ngamehlo, ukunyamekela akuyi kukuthintela.
Ngendlela, i-normate evumelekileyo yansuku zonke ye-nitrate, ngokwemiqathango ye-WHO, i-3.7 mg nganye nge-1 kg yesisindo somzimba.
Izityalo ziyahlukahlukana ngokwazi kwabo ukuqokelela i-nitrate kunye nemiphumo yazo emzimbeni womntu: amanqaku amaninzi (kufika ku-3000 mg) - imifuno enamagqabi, iibhotile, i-radishes kunye ne-melon; Phakathi (400-900 mg) - zucchini, ithanga, iklabishi, izaqathe, ukhukhamba; / ephantsi (50-100 mg) - i-legumes, sorrel, iitapile, anyanisi, utamatisi, izithelo kunye namajikijolo.
Ingxelo epheleleyo yomxholo we-nitrate (i-80% ngaphezu kwesiqhelo!) - isityalo sokuqala. Oku kubangelwe kwiipropati zayo ukuhambisa umswakama emhlabeni (kunye ne-nitrates).
Ngokuqhelekileyo imifuno ephezulu yokutshisa i-greenhouse isonwe ngemifuno eluhlaza.
Khetha iziqhamo ezivuthiweyo uze uzigcine kwifriji (kwindawo yokushisa kwegumbi, ukuxutywa kwe-nitrate ekudleni kwanda). Ngendlela, ama-saladi ezenziwe kwimifuno yasesekuqaleni, kuyinqweneleka ukusebenzisa i-baggy-bayakha i-nitric acid salts.
Umsebenzi wasekhaya
Ngethamsanqa, kukho iindlela ezininzi zokunciphisa umngcipheko wemifuno yokuqala ngaphandle kokushiya ikhitshi lakho! Okokuqala, kufuneka sikhuphe amaqonga aphezulu okanye amathathu kunye nesiphunzi - apho, njengokulawula, i-chemistry iqokelela. Emva koko susela isityalo ngokugqithisileyo (isisombululo sesoda: i-tablespoon e-1 nganye ilitha yamanzi, sukuma ngokuqhelekileyo). Yaye uyihlambulule ngokufanelekileyo: izaqathe kunye namakhukhamba - unqunyulwe kumacala omabili ngo-1 cm, uthinte ama-radishes ukusuka kwi-radishes kunye neetatayi. Kwi-green and lettuce kufuneka badle amaqabunga, kungekhona iziqu (baqokelela i-nitrate). Unokucocisa imifuno ngaphambi kokusebenzisa isigqibo seyure. Oku kuya kulahla i-25-50% ye-nitrate. Ukuba ukupheka okulandelayo kulandela, kubeka elinye i-25-50% ye "chemistry". Indlela eyona ndlela iphumelelayo - ukupheka: faka imifuno ehlutshiwe emanzini ngaphandle kweryuwa (ityuwa - ekuphekeni kokupheka), upheke, uze ucoce umhluzi. Ngendlela, xa udoba, i-nitrate yenzelwe ingozi inokusebenza kakhulu-kuphela ngo-10%. Kodwa omuncu, owamkelekileyo, owamkelekileyo: kwiklabishi elungiselelwe ngale ndlela, sele isele ngomhla wesihlanu inqanaba le-nitrate liyancitshiswa ngesiqingatha.
Kakade ke, kukho ukuphazamiseka ngale ndlela - inani lamavithamini, i-alas, nalo linciphile kakhulu. Yintoni endiyenzayo? Kukho ukhetho oluninzi: unokulibazisa ukuthenga "osemncinci nakusasa" (kwiziqhamo zomhlaba kunye ne-nitrate ngokuqhelekileyo ulawulo olupheleleyo), unako ukukhulisa umkhiqizo we-eco (isaladi, anyanisi, imifuno ecocekileyo) ekhaya kwifestile, okanye unciphise ukulahleka kwe-vitamin kunye ne-green tea okanye isiselo se-ascorbic. .. Okukhethwa nguwe!
Ayikho i-nitrate enoyikekayo ...
Ezinye izazinzulu zicinga ukuba i-nitrate kwiimodareyitha ezilinganayo ziyasebenza kumzimba wethu! Ngokuqhelekileyo umntu uvelisa ngokuzimeleyo ukuya kwi-25-50% yale micimbi yeekhemikhali, ezinye zifumaneka ngokutya. Kwaye ziqulethwe kwimveliso yenyama, amanzi, ubhiya. Kakade emlonyeni womlomo phantsi kweempembelelo ze-nitrate ziguqulwa zibe yi-nitrites, ngamathambo angene kwisisu. Ngokweziphumo zabaphandi baseSweden, kukho ama-nitrosamines angama-carcinogenic, enokubaluleka kwi-nitrogen oxide yabantu (ephucula ukujikeleza kwegazi esiswini, ukukhusela kwi-gastritis, izilonda kunye nemiphumo yeziyobisi ezinonya).
