Kusakanikirana kwa sodium nitrofnolates ndi urea ngati feteleza wokwera ndi feteleza wopaka

① base feteleza kusakaniza quio

Sodium Nitronolates ndi urea amasakanizidwa ngati feteleza wokwera, ndiye kuti, musanafesere kapena kubzala. Chigawo chosakanikirana ndi: 1.8% sodium nitrofnolate (20-30 magalamu), kilogalamu 45 ya urea. Chifukwa chosakaniza, acre amodzi amakhala okwanira. Kuphatikiza apo, kuchuluka kwa urea kumatha kusinthidwa moyenerera, makamaka malinga ndi dothi.

② Pakulucha pang'ono kusakaniza

Ponena za kuchuluka kosakanikirana kovuta, palinso njira ziwiri zosiyana: nthaka yolimba ndi yosangalatsa kwambiri.

Choyamba, njira yolimbikitsira dothi, chiwerengero chosakanikirana ndi 1.8% sodium nitronolates (5-10 ml / g) ndi ma kilogalamu 35 a urea. Malingaliro awa alinso pafupifupi 1 acre. Kukhazikika kwa dothi kumagwiritsa ntchito chiwerengero chosakanikirana ichi, ndipo tikulimbikitsidwa kugwiritsa ntchito njira yogwiritsiridwa ntchito, yomwe ikhale ndi zotsatira zabwino.

Chachiwiri, feteleza feteleza wothira njira, ratio yosakaniza ndi: 1.8% sodium nitfoamments (3 ml g), 50 magalamu a urea, kilogalamu 60 ya madzi.

Komabe, kupopera mbewu kumakhudzidwa ndi nyengo ya mbewu, ndipo iyenera kugwiritsidwa ntchito pakukolola bwino kwambiri. Mwachitsanzo: Mmera womera, maluwa ndi zipatso, ndikutupa, kupopera mbewu mankhwalawa mu nthawi yokolola idzathandiza kwambiri kukula.

Chidule: Mphamvu yakusakanikirana sodium nitrofnolates ndi urea ndi 1 + 1 wamkulu kuposa 2. Urea ndi feteleza wautali, ndi sodium yothetsera bwino kwambiri kulamulidwa ndi mbewu. Kugwiritsa ntchito kosakanikirana kwa urea ndi sodium kumatha kukulitsa zithunzi za masamba, kukonza bwino feteleza wa nayitrogeni, ndikuchulukitsa. Amatchedwa "Colude" kapena "njira yaulimi" ya feteleza ndi mankhwala osokoneza bongo.
