Umahluko phakathi kwe-dap kunye ne-pik yesichumisi

Umahluko ophambili phakathi kwe-dap kunye ne-thatililizer kukuba isichumisi se-daP asinayoi-potassiumkanti isichumisi se-NPK siqulathe i-potassium.

Yintoni isichumisi se-daP?

Izichumisi ze-DAP zimiliselo ye-nitrogen kwaye inkangelene enesiseko esibanzi kwiinjongo zezolimo. Icandelo eliphambili kwesi sichumisi yidammonium phosphate eneefomula zekhemikhali (NH4) 2hpo4. Ngapha koko, igama le-IUPCAC le nqaku yi-dammonium hydrogen phosphate phosphate phosphate phosphate. Kwaye yi-Ammonium enyibilikayo ye-abmonium phosphate.

Kwinkqubo yokuvelisa esi sichumisi, sisabela nge-phosphoric acid nge-ammonia, eyenziwa sisilayidi esishushu esipholileyo, esiyiqengqelekayo kwaye siziinqile ukuze sisebenzise isichumisi esinokusisebenzisa kwifama. Ngapha koko, kufuneka siqhubeke ngokusabela phantsi kweemeko ezilawulwayo kuba impendulo isebenzisa i-acid yesalfuric acid, eyingozi ukuyiphatha. Ke ngoko, inqanaba lezondlo eliqhelekileyo lesi sichumisi yi-18-46-0. Oku kuthetha ukuba, inayo i-nitrogen kwaye iqhume ngomyinge we-18: 46, kodwa ayinayo iPotasium.

Ngokwesiqhelo, sifuna malunga ne-1.5 ukuya kwi-2 yeetoni zelitye le-phosphate, i-0.4 yeetoni zesalfur (kunye neetoni ze-Ammonia kwimveliso ye-DAP. Ngaphezu koko, i-pH yale nto i-7.5 ukuya kwi-8.0. Ke ngoko, ukuba songeza esi sichumisi emhlabeni, sinokwenza i-alkaline PH ijikeleze amaqhinga echumayo emhlabeni; Ke ngoko umsebenzisi kufuneka akuphephe ukongeza inani eliphezulu lesichumisi.

Yintoni isichumisi se-npk?

Izichumisi ze-NPK zingamacandelo amathathu anezichumisi eziluncedo kakhulu kwiinjongo zezolimo. Esi sichumisi sisebenza njengomthombo we-nitrogen, phosphorus kunye ne-potassium. Ke ngoko, ngumthombo obalulekileyo wazo zonke izondlo ezintathu eziphambili ukuba isityalo sifuna ukukhulisa, uphuhliso kunye nokusebenza ngokufanelekileyo. Igama leli gama likwachaza nesondlo esinokubonelela.

Inqanaba le-NPK lindibaniselwano yamanani anika umlinganiso phakathi kwe-nitrogen, phosphrous kunye ne-potassium ebonelelwe sisichumisi. Yindibaniselwano yamanani amathathu, eyahlulwe ngamadada ezimbini. Umzekelo, 10-10-10 ibonisa ukuba isichumisi sibonelela nge-10% yesondlo. Apho, inombolo yokuqala ibhekisa kwipesenti ye-nitrogen (N%), inombolo yesibini) yepesenti ye nkanf (kwiifom ze-P2O5%), kunye nesithathu se-potassium pesenti (K2O%).
