Ammonium nitrate yapeza ntchito yaikulu mu ulimi. Ichi ndi chofunika kwambiri cha fetereza, chomwe chimalimbikitsa kupanga mapangidwe a "maselo" a maselo a zomera. Kuwonjezera pa kugwiritsidwa ntchito monga mchere wamchere, ammonium nitrate ingagwiritsidwe ntchito popanga mabomba.
Chomera chabwino kwambiri padziko lonse
Monga feteleza, ammonium nitrate ndi yofunika kwambiri mu ulimi. Izi ndizoposa theka la nayitrogeni. Nayitrogeni, inanso, ikufunikira kuti mbewu iliyonse ikwaniritsidwe bwino. Kugwiritsidwa ntchito kwa ammonium nitrate kuli kofala m'mundamo, pa dacha payekha. Kuti mukhale osungirako ndi kusungira nthaka, komanso chifukwa chakuti mankhwalawa amatenga chinyezi bwino kwambiri, pakupanga izo kuwonjezera choko, mandimu, zinthu zina zothandizira. Amapangidwa ngati mawonekedwe a mtundu wa mazira-kirimu.
Chifukwa cha chilengedwe chonse, ammonium nitrate ntchito monga kasupe pamwamba kuvala asanadzalemo pafupifupi mitundu yonse ya zomera - masamba mbewu, munda minda. Kawirikawiri, ammonium nitrate amagwiritsidwa ntchito kumera maluwa. Ikhoza kugwiritsidwanso ntchito monga feteleza panthawi ya chitukuko komanso kukula kwa mbewu. Thupili ndiloyenera nthaka iliyonse. Amataya, kumasula nayitrogeni, pa nthaka ya podzolic yomwe imapangitsa mosavuta acidification. Mu dothi lina labwino, maonekedwe awo sasintha pambuyo pa kuwonjezera kwa ammonium nitrate. Kukhoza kwa ammonium nitrate kumadziwikanso kugwira ntchito ngakhale chisanu. Palibe feteleza wina amene amatha kugwira ntchito kutentha pamtunda. Mukamagwiritsa ntchito ammonium nitrate, imayamba kugwira ntchito mwamsanga. Izi sizimasiyana ndi fetereza ina iliyonse. Komabe, sikuvomerezedwa kuti tigwiritse ntchito popanga zovala, chifukwa zingayambitse kupsa kwazomera.
Nthawi ndi njira yopangira
Kodi manyowa zomera ndi ammonium nitrate? Tikulimbikitsidwa kuti tibweretse kuyambira kumayambiriro kwa nyengo yachisanu mpaka pakati pa chilimwe, pomwe pali nsonga zokhazokha za masamba. Mu theka lachiwiri la chilimwe, pamene chipatso chimapangidwa, ntchito yake iyenera kuimitsidwa, pamene kukula kwa tsinde ndi nsonga zingathe kuchepetsa kapangidwe ndi chitukuko cha mwana wosabadwayo. Pa feteleza yemweyo imakhala yakuya mokwanira ndi rakes kapena kumasula, kuti mankhwalawo asamatsukidwe panthawi yamvula kapena kuthirira. Koma ikhozanso kugwiritsidwa ntchito kuthetsera.
- Pamene feteleza ikulima munda, mlingo wa ntchito ya ammonium nitrate ndi 15-20 magalamu pa mita imodzi. Ndipo imabwera pansi pa tchire ndi mitengo pamodzi ndi chiwonetsero chonse cha korona.
- Mukamabzala masamba, 20-30 magalamu pa mita imodzi ya nthaka amagwiritsidwa ntchito kunthaka. Ngati dothi silinakhalepo mpaka pomwepo, ndiye kuti chiwerengero chawonjezeka kufika 50 g.
- Mukamabzala mbande yonjezerani 4-6 magalamu pa mamita kapena masentimita 3-4 patsiku. Mlingo wa ammonium nitrate kwa njirayi ndi 30-40 magalamu pa 10 malita a madzi. Yankho lotere limagwiritsidwa ntchito pa feteleza zomera pa nyengo yokula.
- Sungunulani ammonium nitrate monga fetereza kwa feteleza mitengo ya zipatso mu chiŵerengero cha 20-30 magalamu pa 10 malita a madzi. Ndikofunika kuti apange zovala zapamwamba patangotha sabata imodzi kumapeto kwa maluwa, ndiyeno pambuyo pa masabata 4-5.
Ntchito iliyonse ya ammonium nitrate iyenera kukhala ikuphatikizidwa ndi ulimi wothirira.
Zotsutsana ndi zosungirako
Simungathe kupanga ammonium nitrate ndi utuchi, udzu ndi peat. Pambuyo poyankha, mankhwalawa akhoza kugwira moto. Sikovomerezeka kuti mupange nthawi imodzi ndi feteleza - feteleza, superphosphate. Mwachidule, feteleza sangathe kugwiritsidwa ntchito ku nkhaka, dzungu, zukini ndi sikwashi . Manyowawa amachititsa kuti pakhale kuchuluka kwa nitrates mu zikhalidwe izi.
Kusungirako ammonium nitrate kumafuna chidwi chapadera. Popeza izi zikuphulika, malo osungirako ayenera kukhala kutali ndi zinthu zotentha. Ngati mkangano, mchere wa mchere ukhoza kuyambitsa kupasuka. Kuti muzisunge, mukufunikira malo ozizira ozizira. M'nyumba zapakhomo zimasungidwa pa pepala lapepala kapena mapepala apulasitiki.
