Granular urea: khalidwe mankhwala

Kufotokozera Kwachidule:

Granular urea imakhala ndi ammonia komanso kukoma kwamchere ndipo ndi feteleza wokhala ndi nayitrogeni yemwe amagwira ntchito yofunika kwambiri polimbikitsa kukula kwa mbewu. Ikagwiritsidwa ntchito kunthaka, imadutsa njira ya hydrolysis, kutulutsa ayoni ammonium omwe amatengedwa mosavuta ndi mizu ya zomera.

Izi zimawonjezera kuchuluka kwa nayitrogeni, potero zimalimbikitsa kukula ndikukula kwa mbewu.

Kugwiritsa Ntchito Nayitrogeni Feteleza Urea

kugwiritsa ntchito urea

Zotsatira

1. Paulimi, kugwiritsa ntchito feteleza ndikofunikira kuti mbewu zikule bwino ndikukulitsa zokolola.

2. Granular urea ali ndi kukoma kwake kwa ammonia komanso amchere ndipo ndi feteleza wokhala ndi nayitrogeni wambiri yemwe amagwira ntchito yofunika kwambiri polimbikitsa kukula kwa mbewu. Ikagwiritsidwa ntchito kunthaka, imadutsa njira ya hydrolysis, kutulutsa ayoni ammonium omwe amatengedwa mosavuta ndi mizu ya zomera. Izi zimawonjezera kuchuluka kwa nayitrogeni, potero zimalimbikitsa kukula ndikukula kwa mbewu.

3. Paulimi, kugwiritsa ntchito feteleza ndikofunikira kuti mbewu zikule bwino ndikukulitsa zokolola.

Ubwino

1. Ubwino umodzi waukulu wa urea granular ndi kusungunuka kwake kwakukulu m'madzi ndi ma alcohols osiyanasiyana, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito ndikuwonetsetsa kuti zomera zimadya bwino.
2. Kusinthasintha kwake komanso kugwirizana ndi njira zosiyanasiyana zophatikizira monga kuwulutsa, kuvala pamwamba kapena kuthirira kumapangitsa kukhala chisankho choyamba kwa alimi omwe akufuna kukulitsa kasamalidwe ka feteleza.
3. mankhwala zikuchokera granularurea, kuphatikizira kuwonongeka kwake kukhala biuret, ammonia ndi cyanic acid pa kutentha kwakukulu, kumawonetsa kuthekera kwake kwa kumasulidwa kolamulirika ndi zotsatira zokhalitsa pa zakudya za zomera. Izi zimapangitsa kukhala koyenera kuperekera zakudya zopatsa thanzi nthawi yonse yakukula, kuchepetsa kufunika kobwerezabwereza pafupipafupi.
