Mitundu ndi ntchito za feteleza

Feteleza monga ammonium mankwala feteleza, macroelement madzi sungunuka feteleza, sing'anga chigawo feteleza, feteleza kwachilengedwenso, feteleza organic, multidimensional munda mphamvu anaikira feteleza organic, etc. Feteleza akhoza kupereka zakudya zofunika kuti mbewu zikule ndi chitukuko, kusintha nthaka katundu, ndi kuonjezera mbewu. zokolola ndi khalidwe.Feteleza ndizofunikira pa ulimi.Zomwe zimafunikira pakukula kwa mbewu ndi nayitrogeni, phosphorous, potaziyamu, calcium, ndi magnesium.Kuperewera kwa chinthu chilichonse kudzakhudza kukula ndi kukula kwa mbewu.

Feteleza amatanthawuza gulu la zinthu zomwe zimapereka gawo limodzi kapena zingapo zofunika pazakudya, kukonza dothi, ndikuwonjezera chonde m'nthaka.Ndi imodzi mwazinthu zopangira ulimi.Mwachitsanzo, kusowa kwa nayitrogeni m'zomera kumayambitsa zomera zazifupi komanso zoonda, komanso masamba obiriwira obiriwira monga achikasu-wobiriwira ndi achikasu-lalanje.Nayitrogeni akusowa kwambiri, mbewu zimamera ndi kukhwima msanga, ndipo zokolola zimatsika kwambiri.Pokhapokha powonjezera feteleza wa nayitrogeni m’pamene kuwonongeka kungachepe.

Njira yosungira feteleza:

(1) Feteleza azisungidwa pamalo owuma komanso ozizira, makamaka posunga ammonium bicarbonate, zotengerazo ziyenera kutsekedwa mwamphamvu kuti zisakhudzidwe ndi mpweya.

(2) Manyowa a nayitrojeni asungidwe kutali ndi kuwala kwa dzuwa, zozimitsa moto ndizoletsedwa, ndipo zisaunjike pamodzi ndi dizilo, palafini, nkhuni ndi zinthu zina.

(3) Feteleza wa mankhwala sangaunjike ndi njere, ndipo musagwiritse ntchito feteleza wa mankhwala kulongedza njere, kuti zisasokoneze kumera kwa mbewu.
