Iindaba

1. Isichumiso seNitrojeni: Sinokukhuthaza ukukhula kwamasebe namagqabi ezityalo, siphucule iphotosynthesis yezityalo, sandise umxholo wechlorophyll, kwaye siphucule ukuchuma komhlaba.
2. Isichumiso sePhosphate: Khuthaza ukumila kunye nokudumba kweentyatyambo, yenza izikhondo zezityalo kunye namasebe omelele, iziqhamo ezivuthiweyo kwangethuba, kwaye uphucule ukukhula kwezityalo nokuxhathisa imbalela.
3. Isichumiso sePotassium: Siphucula isiqu sesityalo, siphucula ukuxhathisa izifo zezityalo, ukuxhathisa kwezinambuzane, nokumelana nembalela, kunye nokuphucula umgangatho weziqhamo.

1. Indima yeIsichumisi se-NPK
I-N. P kunye ne-K zibhekisela kwisichumisi se-nitrogen, isichumisi se-phosphorus, kunye nesichumisi se-potassium, kwaye imisebenzi yazo ilandelayo.
1. Isichumiso se-nitrogen
(1) Ukuphucula iphotosynthesis yezityalo, ukukhuthaza ukukhula kwesebe lesityalo kunye namagqabi, ukwandisa umxholo we-chlorophyll, kunye nokuphucula ukuchuma komhlaba.
(2) Ukuba kukho ukunqongophala kwesichumiso senitrogen, izityalo ziya kuba mfutshane, amagqabi azo aya kuba tyheli kwaye abe luhlaza, ukukhula kwawo kuya kucotha, kwaye aziyi kukwazi ukuqhakaza.
(3) Ukuba kukho isichumiso senitrogen eninzi, izicubu zesityalo ziya kuba thambileyo, izikhondo namagqabi aya kuba made kakhulu, ukuxhathisa kwengqele kuya kuncipha, yaye kulula ukosulelwa zizifo nazizinambuzane.
2. Isichumiso sephosphate
(1) Umsebenzi wayo kukwenza iziqu kunye namasebe ezityalo omelele, ukukhuthaza ukubunjwa nokudumba kweentyatyambo, ukwenza iziqhamo zivuthwe kwangethuba, nokuphucula ukuxhathisa kwembalela nokubanda.
(2) Ukuba izityalo ziswele iphosphateisichumisi, zikhula kancinane, amagqabi, iintyatyambo neziqhamo zazo zincinane, yaye iziqhamo zazo zivuthwa kade.
3. Isichumiso sePotassium
(1) Umsebenzi wayo kukwenza izikhondo zezityalo zomelele, ukukhuthaza ukukhula kweengcambu, ukuphucula ukumelana nezifo zezityalo, ukuxhathisa kwezinambuzane, ukumelana nembalela, ukuxhathisa indawo yokuhlala, kunye nokuphucula umgangatho weziqhamo.
(2) Ukuba kukho ukunqongophala kwesichumisi se-potassium, amabala e-necrotic aya kubonakala kwimida yeqabunga lezityalo, kulandele ukubuna kunye necrosis.
(3) Isichumiso se<em>potassium esigqithisileyo sikhokelela ekubeni zibe mfutshane ii<em>internode zezityalo, zibe mfutshane imizimba yezityalo, amagqabi atyheli, yaye kwiimeko ezimandundu, ukufa.
2, Loluphi uhlobo lwesichumiso olulwenzayoIsichumisi se-NPKyeka?
1. Isichumiso se-nitrogen
(1) I-nitrojeni yeyona nto iphambili yezondlo zesichumisi, ingakumbi i-urea, i-Ammonium bicarbonate, i-ammonia, i-ammonium chloride, i-Ammonium nitrate, i-ammonium sulfate, njl njl. I-Urea sisichumisi esiqinileyo esinomxholo ophezulu we-nitrogen.
(2) Kukho iindidi ezahlukahlukeneyo zezichumiso zenitrogen, ezinokwahlulwa zibe sisichumiso senitrogen se<em>nitrate, i<em>ammonium nitrate nitrogen fertilizer, isichumiso se<em>cyanamide nitrogen, isichumiso se<em>ammonia nitrogen, isichumiso se<em>ammonium nitrogen nesichumiso se<em>amide nitrogen.
2. Isichumiso sephosphate
Esona sondlo sesichumiso yi phosphorus, ikakhulu iquka iSuperphosphate, icalcium magnesium phosphate, iphosphate rock powder, ukutya kwamathambo (ukutya kwamathambo esilwanyana, ukutya kwamathambo entlanzi), ibran yerayisi, isikali sentlanzi, iGuano, njl.
3. Isichumiso sePotassium
Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, etc. Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, njl.
