Udindo wa diammonium phosphate Mankhwala a diammonium phosphate ndi amchere, chifukwa chake ndi a feteleza wamchere. Diammonium phosphate ndi feteleza wothamanga kwambiri wa nayitrogeni ndi phosphorous feteleza wokhala ndi phosphorous monga chinthu chachikulu. Ndioyenera mbewu zambiri komanso yoyenera kugwiritsidwa ntchito m'nthaka zosiyanasiyana. Ili ndi ntchito zingapo ndipo itha kugwiritsidwa ntchito ngati feteleza woyambira kapena kuwongolerera. angathe.
Kugwiritsa ntchito diammonium phosphate Diammonium phosphate itha kugwiritsidwa ntchito kutengera mitundu ingapo ya nthaka m'minda ya paddy ndi minda youma. Ndioyenera mbewu zambiri monga mpunga, tirigu, chimanga, mbatata, mtedza, kugwiririra, ndi mtedza. Ndioyenera makamaka mbewu zomwe zimafunikira hydrogen ndi phosphorous monga nzimbe ndi mabokosi amadzi. Diammonium phosphate itha kugwiritsidwa ntchito limodzi ndi ammonium bicarbonate, urea, ammonium chloride, potaziyamu chloride, ammonium nitrate ndi feteleza ena. Pewani kugwiritsa ntchito feteleza wama acidic monga ammonium sulphate ndi superphosphate. Zotsatira pambuyo pogwiritsira ntchito ndizabwino. Limbikitsani kukula kwa mbewu.
Momwe mungagwiritsire ntchito diammonium phosphate
1. Kuyesera kwatsimikizira kuti diammonium phosphate itha kugwiritsidwa ntchito kutengera mitundu ingapo ya nthaka m'minda ya paddy ndi nthaka youma, yoyenera mbewu zambiri monga mpunga, tirigu, chimanga, mbatata, chiponde, kugwiririra, chiponde, ndi zina zambiri, makamaka zoyenera haidrojeni-phosphorous amafuna mbewu monga nzimbe ndi mabokosi amadzi.
2. Diammonium phosphate itha kugwiritsidwa ntchito limodzi ndi ammonium bicarbonate, urea, ammonium chloride, potaziyamu chloride, ammonium nitrate ndi feteleza wina. Pewani kugwiritsa ntchito feteleza wama acidic monga ammonium sulphate ndi superphosphate.
3. Kafukufuku akuwonetsa kuti diammonium phosphate kuphatikiza feteleza wa nayitrogeni ndi potaziyamu (feteleza wokhala ndi klorini sayenera kugwiritsidwa ntchito pazomera zopanda chlorine) ndizoyenera kuthira feteleza wosakaniza ndi mbeu ya 225 ～ 300kg / h; ntchito m'munda wa paddy: Mukatsegula khasu, phatikirani m'madzi osaya; Kugwiritsa ntchito nthaka youma: kugwiritsidwa ntchito kwambiri polima ndi kuphatikiza, kusakaniza nthaka yachonde. Sakanizani diammonium phosphate ndi feteleza wowola ndi pH yopanda ndale ndikugwiritsa ntchito mutapanga manyowa, feteleza ndi othandiza. Mukamapanga feteleza wa mbeu, iyenera kuthiridwa masiku 1 kapena 2 isanafike, mulingo wake ndi 100-150kg / h㎡, ndipo nthaka yachonde imasakanikirana mofananira kuti isakumane mwachindunji pakati pa mbewu ndi feteleza.
4. Pofuna kuthira feteleza wokhala ndi madzi amadzimadzi a phosphate, diammonium phosphate (feteleza wa nayitrogeni ndi potaziyamu kutengera mtundu wa mbeu) uyenera kusungunuka m'madzi ndi chiyerekezo cha 1: 5 kutentha kwapafupi pafupi ndi malo a umuna 1 mpaka 2 masiku asanachitike umuna. Mukasungunuka, tengani njira ya feteleza ndikuisungunula ndi madzi pa 1: 25-30, kapena gwiritsani ntchito mafuta a biogas kuti asungunuke, ndipo kuchuluka kwa njira yothetsera madzi ndi madzi nthawi 60-80. Msolo wa umuna uyenera kukhala wopepuka munthaka wa mbeu kapena nthaka ikauma; kuchuluka kwa umuna kumatha kukulitsidwa moyenera nthawi yazomera zazikulu ndipo dothi limakhala lonyowa.
Contraindications yogwiritsa ntchito diammonium phosphate Diammonium phosphate ili ndi ma phosphate ions ambiri. Pambuyo pothira feteleza mbewu, imakulitsa acidity ya nthaka panthaka ya acidic, yomwe ingakhudze kukula kwa mbewu. Samalani kuti musagwiritse ntchito ngati zovala zapamwamba. Kufalitsa granular diammonium phosphate pamwamba, mizu siyidzayamwa, ndipo zotsatira za feteleza zidzatayika. Pewani kusakanikirana ndi feteleza acidic, monga ammonium sulphate, superphosphate, etc.
