Nthawi yobereketsa Mukamathirira ndi kuthira feteleza, kutentha kwamadzi kuyenera kukhala pafupi kwambiri kutentha kwa pansi ndi kutentha kwa mpweya, ndipo musadzaze madzi. Kuthirira wowonjezera kutentha m'nyengo yozizira, yesetsani kuthirira m'mawa; chilimwe, yesani kuthirira masana kapena madzulo. Ngati simukusowa chotsitsa, yesani kuthira madzi pang'ono momwe mungathere.
Madzi osefukira ndiosavuta kuyambitsa kukhathamira kwa nthaka, kupuma kwa mizu kumalephereka, zomwe zimakhudza kuyamwa kwa michere, ndipo ndizosavuta kuvunda mizu ndi mitengo yakufa. Kulimbikitsa "kulima kwamtunda" kumathandizira kukolola kwambiri.
Manyowa osungunuka m'madzi amangopeza zokolola zabwino komanso zabwino mwa umuna wasayansi. Manyowa asayansi sikuti amangokhudza njira yogawa komanso mtundu wa magawidwewo, komanso mulingo wa sayansi.
Nthawi zambiri, 50% ya feteleza wosungunuka m'madzi amagwiritsidwa ntchito pazomera zam'munda, ndipo kuchuluka kwake mu pafupifupi makilogalamu 5, kuphatikiza pafupifupi 0,5 makilogalamu azinthu zosungunuka zamadzi humic acid, amino acid, chitin, ndi zina zambiri. nayitrogeni, phosphorous ndi potaziyamu michere, itha kuthandizanso kukaniza matenda, kukana chilala, kukana kuzizira, ndikuchepetsa kuchepa.
Madzi osungunuka feteleza sayansi yogwiritsa ntchito ukadaulo
Kutenga mbewu zamasamba monga nkhaka ndi tomato monga chitsanzo, nkhaka ndi tomato ndi mbewu zomwe zimafalikira, kubala, ndikukolola nthawi zonse. Malinga ndi kuyesa kwa Unduna wa Zamalonda, 1000 kg iliyonse ya nkhaka imafuna pafupifupi 3 kg ya nayitrogeni, 1 kg ya phosphorous pentoxide, ndi makutidwe ndi okosijeni. Potaziyamu 2.5 kg, calcium oxide 1.5 kg, magnesium oxide 0.5 kg.
Nkhaka, tomato ndi mbewu zina zimakhala ndi feteleza wochuluka wa nayitrogeni woyambirira kukula kwamasamba, ndipo phosphorous ndi boron siziyenera kusowa nthawi yamaluwa. Munthawi yobzala zipatso, potaziyamu ndi calcium ziyenera kuchulukitsidwa, ndipo feteleza wa magnesium ayenera kuwonjezeredwa pakati komanso mochedwa. Izi zikutanthauza kuti, kuchuluka kwa michere kuyenera kukwaniritsidwa nthawi yonse yakukula.
Pankhani yodziwa kuchuluka kwa michere, tiyeneranso kulabadira kuphatikiza kophatikizana kwa zinthu zosungunuka m'madzi, kuphatikiza kugwiritsa ntchito feteleza wa mpweya wa carbon dioxide.
Pewani kugwedeza mwachindunji ndikugwiritsanso ntchito kuchepetsedwa kwachiwiri. Manyowa osungunuka m'madzi amakhala ndi michere yambiri kuposa fetereza wamba, ndipo mulingo wake ndi wocheperako. Kupopera mbewu mankhwalawa mwachindunji kumapangitsa mbande zotentha kuwononga mizu ndi mbande zofooka. Kuchepetsa kwachiwiri sikuti kumangothandiza kugwiritsa ntchito feteleza yunifolomu, komanso kumathandizira kugwiritsa ntchito feteleza.
