Yintoni oyifunayo ukwazi ngemifuno yasendle?

Kakade ekupheleni kukaFebruwari okanye ekuqaleni kukaKwindla, sinokukwazi ukuthenga imifuno yokuqala, emva koko, kuyinto enomdla ukuzithobela iivithamini emva kwebusika ende. Iimvithamini zendalo aziyingozi nakubani na, nangona zibiza kakhulu. Kodwa kungenjalo, kuba imifuno entsha ingaba yingozi kakhulu. "IiVithamini zamaGreenhouse"
Kwiimifuno ezitshatyalaliswayo kunye nemifuno yomhlaba ayinalo kuphela ukuthanda izinto, kodwa kunye nemichiza yeekhemikhali. Emva koko, ukwenza iifuno zivuthwe, zisebenzisa ezininzi izichumisi kunye nezinto ezikhuthaza. Kunengqiqo ukuba ngaphezu kokuchumisa, ukonakalisa isiqhamo ngakumbi.

Ubuninzi be nitrate
I-nitrate iyinxalenye ye-nitrogen enceda izityalo zikhule ngokukhawuleza. Ukuba akukho zincithamini ezingenayo i-antioxidant, i-nitrate ibonakala ngokukhawuleza, engabangeli nje utyhefu, kodwa i-oksijini yindlala yamathambo omzimba, kwaye ukuba isetyenziswe rhoqo, kwaye kukho umngcipheko wokufumana izicubu ezinzima.

Ukugqithiswa kwe-nitrate, umnqweno we-agronomist ukukhula imifuno ayikho rhoqo ngokukhawuleza, oku kuya kwenzeka ngenxa yokungabikho kokugcinwa kobugcisa bokulima, ukushisa okungafanelekanga, urhulumente wamanzi, ukunyuka kwamanzi.

Kodwa akusiyo yonke imifuno iqokelela i-nitrate. Isipinashi, i-dill, i-anyanisi, israyi, i-lettuce, iklabishi, israyi, izaqathe, isilimo esidliwayo esinamagatsha anamanzi, i-zucchini, i-broccoli, iicukom ziyakwazi ukuqokelela. Ekhuselekileyo kulo mbandela yiitamatati, amahluma aseBrussels, i-pepper, amazambane kunye namaqabunga.

Iingcebiso ezifanelekileyo zokuthenga imifuno

• xa uthengela umgqomo waseBulgaria, qaphela ukuba "indebe" yakhe kufuneka ibe luhlaza;
• Isihlunu akufanele sibe mkhulu kakhulu, nzima, singenazo izihlamba kunye neqhawulo;
• xa uthengela iklabishi encinane, ukhethe ngohlaza oluhlaza, olutsha, olumanzi;
• nayiphi imifuno kunye namakhukhamba kufuneka abe ngumbala omnyama obumnyama. Iikhukhamba akufanele zizithambile kwaye zikhuni;
• kwimifuno emikhulu kune "chemistry";
• Ukuba usenokugqiba ukuthenga imifuno emitsha, ungcono ukuya evenkile, kwaye ungahambi kwimarike. Ngoko unokuqiniseka ngokufumaneka kweziqinisekiso zekhwalithi ezithetha ngokukhuseleko kwemveliso kunye nezinga eliqhelekileyo le-nitrate.

Ewe, akunakwenzeka ukuba ungabandakanyi ngokupheleleyo ukuthengwa kwemveliso ngaphandle kwe-nitrate. Kodwa into encinci iyakwenzeka. Oku kwenziwa njani?

• ngaphambi kokuba uqale ukupheka imifuno, uhlambe kakuhle, ususe iindawo eziluhlaza zeziqhamo, ngokukodwa iifatati kunye neeqathi;
• ngoko kufuneka ubeke imifuno imizuzu engama-20 kumanzi abandayo, uwukhuphe, uze uyiguqule ngokucocekileyo kwakhona;
• Iikhukhamba kunye neerdish kungcono ukunqanda ulusu, unqumle umsila;
• ekudleni akufuneki ukuba adle iziqu zemifuno, kukho izinto ezinobungozi ngaphezu kwazo kuneziqu;
• ukuba imifuno ayinakunyango lokushushu, ufefe nge juisi ye-lemon - i-asidi iya kunciphisa i-nitrates;
• xa unyango lwamafutha, i-nitrate iya kuma-80%, kodwa awulibali ukukha amanzi ngokukhawuleza ukupheka, kwaye uwatyulele;
• Akufuneki ukugcina imifuno ixesha elide kubanda, ngakumbi ukusika imifuno.

Akunakwenzeka ukuba kunikwe abantwana abangaphantsi kweminyaka eyi-8 ubudala imifuno, njengoko inkqubo yabo yokugaya ayinamandla kakhulu ukuwamkela nokugaya i-nitrates. Ukuba umntu omdala engaboni nantoni na eyingozi, umntwana unokufumana ubunetyhefu obukhulu.

Kuyafana nabantu abadala, ngakumbi abo baneentliziyo okanye iingxaki zokuphefumula. Imifuno yexesha eliphambene nelokukhulelwa kwabamama abakhulelweyo nabangcolileyo, kuba kukho umngcipheko wesifo senkqubo yesifo somntwana.

Ukuba uvakalelwa kukuba unetyhefu, waqala ukuhlanza, uhudo, isisu, kufuneka uhlambulule isisu sakho ngokukhawuleza, ubangele ukuhlanza, kwaye usebenzise i-charcoal (1 tablet nganye nge-10 kg yesisindo somzimba womntu). Ukuba kungakapheli iiyure ezimbalwa imeko ayizange iphuculwe, kungcono ukubona ugqirha.
