Sizinsinsi kuti kupambana kwa mbeu zambiri kumadalira makamaka kuwonjezerapo feteleza. Mmodzi mwa otchuka pakati pa mchere feteleza ndi saltpetre. Tiyeni timudziwe bwino.
Kodi feteleza wa saltpeter ndi chiyani?
Ndipotu, nitre nthawi zambiri amamvetsa ngati ammonium nitrate. Thupili, lotulutsidwa monga mawonekedwe a granules kapena ufa, amatchedwanso ammonium nitrate kapena ammonium nitrate. Saltpeter ndi gwero la nayitrogeni, chimanga chachikulu cha zomera, kukula kwake, chitukuko. Komanso, Kuwonjezera kwa ammonium nitrate kumalimbikitsa kuwonjezeka kwa mbewu zokolola ndi nthawi ya fruiting. Mwa njira, saltpetre ndi imodzi mwa mchere wambiri padziko lonse lapansi: ndi yotchipa, yogwira ntchito, yotsekemera mu madzi. Ili ndi 34% ya nitrojeni.
Kugwiritsa ntchito nitrate ya feteleza
Ammonium nitrate amagwiritsidwa ntchito monga fetereza kwa pafupifupi mbewu zonse ndi mitundu yonse ya dothi (kupatula podzolic). Kawirikawiri, ammonium nitrate amagwiritsidwa ntchito m'chaka pamene afesedwa, kenako ngati feteleza. Mwa njirayi, feteleza nitrate ikuphatikizapo potaziyamu ndi phosphorous kukwaniritsa zokolola zambiri.
Kuyeza mlingo, ammonium nitrate ndi chisindikizo cha nthaka nthawi zambiri amwazikana ndi kuchuluka kwa 10-20 g pa 1 m & sup2 yolima nthaka. M'mayiko osawonongeka, kuchuluka kwa saltpeter kungawonjezereke kufika 30-50 g pa m & sup2. Mukamabzala mbande mu dzenje lililonse limalimbikitsidwa kupanga 3-4 g wa feteleza. M'tsogolo, monga pamwamba kuvala, 30 g wa ammonium nitrate amasungunuka 10 malita a madzi ndipo njirayi imathiridwa ndi 10 m & sup2 dothi. Saltpeter ingayambe kufalikira pamwamba pa nthaka, ndikutsanulira madzi okwanira. Koma mulimonsemo, musati muwonjezere mlingo umenewu wokha.
Chonde dziwani kuti mwa kudya kwa foliar, ammonium nitrate sangagwiritsidwe ntchito! Izi zidzatentha zomera. Musagwiritse ntchito saltpeter kudyetsa zukini , nkhaka, dzungu, zomwe zingadzikundikire zoipa ku thanzi la nitrates.
