Monga akatswiri ogulitsa feteleza ndi phukusi la feteleza, tadzipereka kupereka zinthu zapamwamba zomwe sizimangolimbikitsa kukula kwa mbewu komanso kuganizira momwe chilengedwe chimakhudzira ntchito yawo. Chimodzi mwazinthu zofunika kwambiri pazogulitsa zathu ndi ammonium chloride, feteleza wa potaziyamu (K) yemwe amagwira ntchito yofunika kwambiri popititsa patsogolo zokolola komanso mtundu wa zomera zomwe zimabzalidwa munthaka yopanda michere. Munkhani iyi, tiwona bwino za mankhwala aammonium kloridi mcherendikuwunika momwe amakhudzira chilengedwe.
Mankhwala a ammonium chloride:
Ammonium chloride, formula ya mankhwala NH4Cl, ndi mchere wa crystalline womwe umasungunuka kwambiri m'madzi. Ndi hygroscopic, kutanthauza kuti imatenga chinyezi kuchokera mumlengalenga. Katunduyu amaupanga kukhala gwero lofunikira la nayitrogeni pa ubwamuna wa zomera chifukwa umasungunuka mosavuta ndi kutengedwa ndi mizu ya zomera. Kuphatikiza apo, ammonium chloride imakhala ndi nayitrogeni wambiri, zomwe zimapangitsa kuti ikhale gwero lazakudya zofunika kwambiri pakukula kwa mbewu.
Ammonium chloride ikagwiritsidwa ntchito m'nthaka, imadutsa njira yotchedwa nitrification, momwe mabakiteriya a nthaka amasintha nayitrogeni mu mawonekedwe a ammonium (NH4+) kukhala nitrate (NO3-). Kutembenuka kumeneku n'kofunika chifukwa zomera makamaka zimayamwa nayitrogeni mu mawonekedwe a nitrates. Chifukwa chake, ammonium chloride imakhala ngati nkhokwe ya nayitrogeni yomwe imatha kumasulidwa pang'onopang'ono ndikugwiritsidwa ntchito ndi zomera pakapita nthawi.
Mphamvu ya ammonium chloride pa chilengedwe:
Pameneammonium kloridindi feteleza wogwira mtima, kugwiritsa ntchito kwake kumatha kuwononga chilengedwe ngati sikuyendetsedwa bwino. Chimodzi mwazinthu zomwe zimadetsa nkhawa kwambiri ndi kuthekera kwa kutulutsa nayitrogeni. Kugwiritsa ntchito kwambiri ammonium chloride kapena feteleza wina wopangidwa ndi nayitrogeni kumatha kupangitsa kuti ma nitrati alowe m'madzi apansi, zomwe zingawononge madzi abwino komanso zachilengedwe zam'madzi.
Kuphatikiza apo, njira ya nitrification m'nthaka imatsogolera kutulutsa kwa nitrous oxide (N2O), mpweya wowonjezera kutentha womwe umathandizira kusintha kwanyengo. Ndikofunikira kuti alimi ndi alimi atsatire njira zabwino zoyendetsera ntchito kuti achepetse kutayika kwa nayitrogeni ndikuchepetsa kuwononga chilengedwe chifukwa chogwiritsa ntchito ammonium chloride.
Kugwiritsiridwa ntchito kosatha kwa ammonium chloride:
Pofuna kuthana ndi zovuta zachilengedwe zomwe zimagwirizana ndiammonium kloridi mchere, ndikofunikira kutsatira njira zokhazikika pakugwiritsa ntchito kwake. Izi zikuphatikizapo kasamalidwe kabwino ka michere, komwe kumasintha kagwiridwe kake kuti kagwirizane ndi zosowa zenizeni za mbewu zomwe zikulimidwa. Kuphatikiza apo, kuphatikizira machitidwe monga kubzala mbewu zokulirapo, kasinthasintha wa mbewu, ndi kugwiritsa ntchito zoletsa nitrification zingathandize kuchepetsa kutulutsa kwa nayitrogeni ndikuchepetsa kutulutsa mpweya wowonjezera kutentha.
Mwachidule, ammonium chloride ndi feteleza wa potaziyamu wamtengo wapatali yemwe amakhudza kwambiri zakudya komanso kukula kwa mbewu. Komabe, mankhwala ake ndi zotsatira zake zachilengedwe ziyenera kumveka kuti zitsimikizire kuti zikugwiritsidwa ntchito moyenera. Mwa kulimbikitsa njira zokhazikika zaulimi ndikudziwitsa anthu za kugwiritsa ntchito bwino kwa ammonium chloride, titha kugwiritsa ntchito zopindulitsa zake ndikuchepetsa momwe chilengedwe chimakhalira. Monga ogulitsa odalirika, ndife odzipereka kuthandiza makasitomala athu kugwiritsa ntchito feteleza m'njira yosamalira zachilengedwe, zomwe zimathandizira kuti chilengedwe chathu chikhale ndi thanzi lanthawi yayitali.
