Nayitrogeni imathandizira kuti chitukuko chitha msanga komanso bwino, ndipo sulufule amafunikira kubereka zipatso zokoma. Kupanga zinthu izi ndi zikhalidwe zimapereka kugwiritsa ntchito ammonium sulphate feteleza.
Ammonium sulphate - makhalidwe
Mu maonekedwe, feteleza amawoneka ngati ufa wonyezimira wonyezimira. Zili ndi ubwino wotere:
- wokhazikika bwino mmadzi;
- sichikudya mkate panthawi yosungirako;
- Mitengo imasankha sulfure ndi nayitrogeni padziko lapansi. Chosowa chimayambitsa kuwonongeka kwa masamba, zipatso komanso imfa ya zomera. Feteleza ndi othandiza kwambiri chifukwa chafutukuka, dothi losasunthika. Kugwiritsidwa ntchito kwakukulu ndi zinthu zina zothandiza kudzakhudza dziko lapansi ndi zinthu zofunikira.
Sulphate ya ammonium ndi feteleza, zomwe sizidzavulaza munthu kapena nyama. Choncho, siwonjezeka kokha ku mizu, koma imadzinso ndi masamba ndi zimayambira. Wothandizira akugwiritsidwa ntchito mosasamala nyengo ya nyengo. Ndikofunika kudziwa kuti zotsatirazi zidzagwiritsidwa ntchito mobwerezabwereza.
Ntchito ya ammonium sulphate
Sulphate ya ammonium yapeza ntchito yaikulu mu ulimi, imagwiritsidwa ntchito m'mayiko am'munda kumene kabichi, turnips, mbatata, beets, radishes amakula. Koma popeza izi siziri kuvala pamwamba, chigwiritsiro ntchitocho chidzakhala ndi zotsatira zowonongeka pa tirigu, soya, oats, buckwheat , flax.
Ammonium sulphate imagwiritsidwanso ntchito kwambiri m'dzikoli. Cholingacho chikakonzedwa kuti chikatengenso mbewu kuchokera kumadera mazana asanu ndi limodzi, ndiye kuti palibe chakudya chowonjezera chofunikira. Wothandizira sikuti amangoponyedwa pamabedi, koma amadziwika pamodzi ndi kukumba dziko lapansi. Koposa zonse, ndi oyenera masamba omwe alibe sulufule.
Nthawi yoyenera kugwiritsa ntchito feteleza ndi yophukira. Ngati muwonjezerapo kumapeto kwa nyengo, zidzalimbikitsa kukula kwa zomera, ndipo potsiriza mudzatha kukolola zochuluka.
Pogwiritsa ntchito ammonium sulfate, mfundo zotsatirazi ziyenera kuganiziridwa:
- Kawirikawiri kwa 1 sq.m. masamba 30-40 g ya feteleza. Ngati ndi bwino kuchepetsa kapena kuchulukitsa mlingo, zomera zokha zidzanena.
- Ngati chovala chokongoletsera chidawonjezeredwa kamodzi, izi sizingakhudze katundu wa nthaka. Pogwiritsa ntchito mobwerezabwereza, dziko lapansi lidzakhala lolimba kwambiri. Malowa sapezeka pa nthaka ya alkaline komanso yopanda ndale, koma ndibwino kulisakaniza ndi asidi kotero kuti amalepheretsa acidification m'nthaka.
- Ammonium sulphate sagwirizana ndi nkhuni ndi tomaslag.
- Sulphate ya ammonium yodalirika ikuphatikizidwa ndi mitundu ina ya feteleza. Izi ndizo chifukwa chakuti zilibe zinthu zina zofunika zofunika kwa zomera.
Choncho, ammonium sulfate idzakuthandizira kupeza zokolola zambiri za mbewu zina.
