Feteleza wa Starter ndi Zolakwa Zofunika Kwambiri

Za zolakwitsa zofala kwambiri popanga ma feteleza oyambira, akatswiri a State University of Mississippi, USA, Larry Artham ndi Eric Larson amauzidwa.

Feteleza Wotentha

Ngati feteleza amalowetsedwa pamodzi ndi mbewu kapena pafupi kwambiri ndi iwo akabzala, ndizotheka kuwotcha.

Ma feteleza ambiri ndi mchere womwe umasungunuka mu ma ion omwe amafanane ndi madzi. Ingoganizirani mchere wamchere, womwe umasungunuka madzi kukhala oyenera komanso osalimbikitsa a Namani ndi zigawo. Kutha kumeneku kumapangitsa dontho lokakamiza, kotero madzi amasunthira kuchokera ku dothi lophukira (I.E. Osmosis). Zomera zimatha kuzimiririka, kubweza ndikufa chifukwa chosowa madzi. Izi zimatchedwa feteleza kuyaka ndipo zimatha kuwonongeka kwambiri kumera.

Izi muchikhalidwe mwambo mwamwambo sizimachitika, chifukwa zimagawidwa kudera lalikulu.

Momwemonso, kuyambira feteleza wokhala ndi ma cm 5 cm pamwamba ndi 5 cm pansipa ndi njira yopangidwira kulumikizana ndi mbande. Feteleza wosungunuka bwino wokhala ndi mndandanda wotsika wa saline ayenera kugwiritsidwa ntchito, monga ammonium polyphoshate (10-34-0) kapena Orthofosphatetes. Ogulitsa ogulitsa ndi alangizi ayenera kudziwa zoyenera kutsatira izi.

Ammonia poizoni

Mukamagwiritsa ntchito feteleza wina wa nayitrogeni, pali chiopsezo chowonjezera chovulala, chomwe chingayembekezeredwe pazinthu zamchere ngati ammonia amagawidwa nthaka polowa munthaka.

Ammonia ndi poizoni ndipo amatha kulowa momasuka mu maselo obzala.

Urea, Cas, ammonium thiosulpate ndi diammonamosphate (dap) imayimiranso zovuta zambiri zokhudzana ndi ma ammonia kuposa Mamal Map kapena ammonium nitrate.

Kuchuluka kwa ammonia kungathandize chifukwa cha mfundo zapamwamba kapena zochuluka za nthaka, kapena chifukwa cha zomwe mwakhala nazo pafupi ndi feteleza.

Nyengo ndi dothi ndizofunikira

Mikhalidwe ya dothi ndiyofunikira kuti mudziwe chifukwa chake kuvulala kumabwera zaka zingapo, osati kwa ena.

Kututa kotuta kamapezekanso ngati mbande zomera pamtunda wamchenga wokhala ndi zinthu zochepa zomwe zimakhudzidwa mwachindunji ndi feteleza.

Nyengo youma imakulitsa mwayi wovulala. M'dothi lonyowa, mchere wopanda feteleza umangofesedwa ndi kusiyanasiyana kuchokera ku Mzere, koma kusokonezeka sikuchitika m'madothi owuma. Feteleza wokhazikika umawonjezera chiopsezo chowotcha.

Dothi lokhala ndi ma cent yotsika mtengo wokhala ndi mawonekedwe otsika ndi zinthu zotsika kwambiri zomwe sizimatha kuphatikiza feteleza kuposa dothi lomwe limakhala ndi luso lapamwamba (lopindika).

Kutentha kwa nthaka kulinso gawo la vutoli, popeza mizu yake imamera pang'onopang'ono m'dothi lozizira, ndipo limayatsidwa ndi feteleza wautali kwambiri.
