Ammonium nitrate ndi feteleza wachilengedwe yemwe amagwiritsidwa ntchito kwambiri polima mbewu zam'munda zosiyanasiyana. Amapangidwa momwe amapangira magawo ang'onoang'ono ngati mawonekedwe, oyera kapena oyera.
Makhalidwe azamankhwala
Manyowa ali ndi 34% nayitrogeni. Poti zimatha kumizidwa ndi mbeu, sulfure yaying'ono (mpaka 14%) imaphatikizidwanso pokonzekera. Kugwiritsa ntchito ammonium nitrate kumangokhala chifukwa chovala muzu, kugwiritsa ntchito mwachindunji mbewuyo m'njira yothetsera kungayambitse kutentha kwa masamba, zomwe zingachititse kuti mbewu zife.
Popeza nayitrogeni yemwe ali pokonzekerayo ali ndi katundu woti asatuluke, mutatsegula phukusi ndi feteleza liyenera kugwiritsidwa ntchito mwezi wamawa. Nitrate yosindikizidwa imatha kusungidwa osapitilira miyezi isanu ndi umodzi m'chipinda chozizira, chotetezedwa ndi dzuwa.
Pothira feteleza kutentha mpaka madigiri 33, amatha kuphulika.
Ammonium nitrate kanthu
Cholinga chachikulu cha feteleza ndikupereka mbewu zomwe zikukula ndi nayitrogeni. Komabe, fetelezayu amatetezanso mbewu ku mabakiteriya osiyanasiyana komanso bowa zomwe zimapezeka m'nthaka. Izi ndizofunikira makamaka ngati sizotheka kuyendetsa mbewu. Chizindikiro cha ammonium nitrate ndi momwe zimakhalira ndi kutentha kochepa.
Kuyambitsa munthawi yomweyo ammonium nitrate ndi utuchi, udzu kapena zinthu zina "zophatikizika" sikuloledwa. Mukamayanjana, amatha kugwira moto.
Zolemba zogwiritsira ntchito
Monga feteleza onse a nayitrogeni, ammonium nitrate imagwiritsidwa ntchito masika ndi chilimwe, pamene mbewu za m'munda zikukula mwachangu ndikufunika nayitrogeni. Kugwiritsa ntchito koyamba m'mundamu kuchitika ngakhale kubzala kusanayambike, kumwaza masamba m'malo ndikuwadzaza ndi peyala m'nthaka. Pa lalikulu. m. pamtunda adzafunika 20 mpaka 50 g wa mankhwalawo, kutengera ndi nthaka. Uwu ndiye chakudya chachikulu.
M'tsogolomu, feteleza wa ammonium nitrate amagwiritsidwa ntchito m'munda monga feteleza wowonjezera wamasamba:
- Mukabzala mbande za tomato, tsabola ndi mavwende - onjezani 1 tbsp. l saltpeter pachitsime chilichonse ndi kutsanulira bwino.
- Mukabzala mbatata - onjezerani mabowo.
- M'nyengo yachilimwe kudyetsa mbewu, pomwe limachita maluwa ndikupanga thumba losunga mazira, kuwaza feteleza pamalowo pamlingo wa 5 g pa 1 sq. Km. m
- Pothira feteleza mbewu - chovala chimodzi pamwamba popanga mankhwalawo mu kanjira (kapena mzere) wa 5 g pa 1 sq. m.Zikhale patatha milungu itatu mutamera kumera.
- Pothirira mbewu pakumera - konzani njira ya 30 g ya mankhwalawa ndi ndowa. Thirani pansi pa muzu, kupewa kugwa pamasamba. Zovala pamwamba pamatumbo mbatata zimachitika bwino nthawi yoyamba.
Sitikulimbikitsidwa kuphatikiza dzungu, nkhaka, squash ndi squash ndi ammonium nitrate kuti tipewe kudzikundikira kwa nitrate.
Chovala chomaliza chomaliza chikuyenera kuchitika masiku 15-20 musanakolole.
