1. Munda waulimi

(1) Kuletsa nitrification:DMPP CAS 202842-98-6Zingalepheretse kwambiri kusintha kwa ammonium nayitrogeni kukhala nitrate nayitrogeni m'nthaka. Zikawonjezeredwa ku feteleza zaulimi monga feteleza wa nayitrogeni ndi feteleza wophatikizika, zimatha kuchepetsa kutuluka kwa nayitrogeni kapena kusinthasintha kwa feteleza, kusunga ammonium nayitrogeni m'nthaka kwa nthawi yayitali, kukweza kuchuluka kwa nayitrogeni yomwe imagwiritsidwa ntchito mu feteleza, ndikuwonjezera nthawi yogwira ntchito ya feteleza, mpaka milungu 4-10.

(2) Limbikitsani kuyamwa kwa michere:DMPPZimathandiza kupititsa patsogolo kuyamwa bwino kwa zinthu zochepa ndi michere ina ndi mbewu, kulamulira pH ya nthaka ya rhizosphere, kusintha kapangidwe ka nthaka, ndikuwonjezera ntchito ya nthaka.

(3) Kukweza ubwino wa mbewu:DMPPZingachepetse kuchuluka kwa NO₃⁻ m'mbewu ndi zinthu zokolola, kuwonjezera kuchuluka kwa vitamini C, amino acid, shuga wosungunuka ndi zinc m'zinthu zaulimi, ndikukweza ubwino wa mbewu.

(4) Kukweza phindu la zachuma: Mwa kuwonjezera zokolola, kuchepetsa kuchuluka kwa feteleza zomwe zimagwiritsidwa ntchito komanso kuchuluka kwa feteleza zomwe zimagwiritsidwa ntchito, phindu la feteleza likhoza kuwonjezeka.

2. Gawo la zamankhwala:DMPPndipo zochokera ku mankhwalawa zili ndi phindu lalikulu pamankhwala ndipo zingagwiritsidwe ntchito ngati mankhwala oyenera kugwiritsa ntchito mankhwala oletsa mabakiteriya, mavairasi kapena oletsa chotupa. Akuyembekezeka kupanga mankhwala atsopano ogwira ntchito bwino, poizoni wochepa komanso osiyanasiyana, koma ambiri a iwo akadali mu gawo lofufuza.

3. Gawo la sayansi ya zipangizo:DMPPingagwiritsidwe ntchito ngati choyambira kapena chowonjezera pa zinthu zogwirira ntchito komanso kuphatikiza ndi ma polima, zinthu zosapangidwa ndi chilengedwe, ndi zina zotero kuti ikonzekere zinthu zatsopano zomwe zili ndi ntchito zinazake. DMPP ili ndi mwayi waukulu wogwiritsidwa ntchito mu zamagetsi, zamagetsi, mphamvu ndi zina.

Ubwino

(1) Zobiriwira komanso zosawononga chilengedwe: Zinthu zomwe zimawonongeka m'nthaka ndi phosphate, madzi, carbon dioxide, ndi nitrogen oxides. Ndi zotetezeka ku zinthu zachilengedwe monga nthaka, tizilombo toyambitsa matenda, ndi madzi, sizingayambitse kuipitsa chilengedwe kwa nthawi yayitali, ndipo zimakwaniritsa zofunikira za ulimi wobiriwira ndi chitukuko chokhazikika.

(2) Chitetezo chapamwamba:DMPPSichivulaza zomera, chilibe zotsalira mu zinthu zaulimi, ndipo ndi chotetezeka kwa anthu ndi nyama. (3) Sichidzavulaza thanzi la anthu ndi kukula kwa ziweto, ndipo ndi chotetezeka komanso chodalirika kugwiritsa ntchito.

Kukhazikika bwino kwa mankhwala: DMPP ili ndi kukhazikika bwino kwa mankhwala. Pansi pa nthawi yosungira ndi kugwiritsa ntchito bwino, imatha kusunga kukhazikika kwa kapangidwe ka mankhwala ndi zinthu zake, sikophweka kuwola ndi kuwonongeka, ndipo ndi yosavuta kusunga ndi kunyamula.

(4) Yosavuta kugwiritsa ntchito:DMPPIli ndi madzi osungunuka bwino ndipo imatha kusakanizidwa ndi feteleza mu mawonekedwe olimba kapena amadzimadzi. Ndi yosinthasintha kwambiri komanso yosavuta kugwiritsa ntchito m'njira zosiyanasiyana zopangira ulimi ndi njira zoberekera.

(5) Kugwiritsa ntchito bwino kwambiri komanso poizoni wochepa: Kungowonjezera pang'ono kokha kumafunika kuti pakhale mphamvu yoletsa nitrification. Kuwonjezera pang'ono kungathandize kwambiri kugwiritsa ntchito feteleza wa nayitrogeni, kuchepetsa kutayika kwa feteleza ndi kuipitsa chilengedwe, komanso kumachepetsa poizoni komanso kuwononga chilengedwe.
