1. Nitrogen fertilizer: E mafai ona faʻaleleia le tuputupu aʻe o lala laau ma laulaau, faʻaleleia le photosynthesis o laau, faʻateleina le chlorophyll content, ma faʻaleleia le faʻaleleia o le eleele.
2. Phosphate fertilizer: Faʻaleleia le faʻavaeina ma le fuga o fugalaʻau fugalaʻau, faʻamalosi laʻau ma lala laau, fua vave fua, ma faʻaleleia le malulu ma le lamala o laau.
3. Fugalaau o le potassium: Faʻaleleia le laʻau o laʻau, faʻaleleia le faʻamaʻi o laʻau, tetee atu i iniseti, ma le lamala, ma faʻaleleia le lelei o fualaau aina.
1. O le Matafaioi aNPK Fertilizer
O le N. P ma le K o loʻo faʻatatau i le faʻalaʻau o le nitrogen, phosphorus fertilizer, ma le potassium fertilizer, ma o latou galuega e faʻapea.
1. Faila nitrogen
(1) Faʻaleleia le photosynthesis o laʻau, faʻaleleia lala o laʻau ma lau laulaau, faʻateleina le chlorophyll, ma faʻaleleia le faʻaleleia o le eleele.
(2) Afai e leai se faʻamaʻi faʻamaʻi, o le a pupuʻu laau, o le a lanu samasama ma lanumeamata o latou lau, o le a tuai lo latou tuputupu ae, ma o le a le mafai ona fuga.
(3) Afai e tele naua le faʻamaʻi faʻamaʻi, o le a vaivai le aano o laʻau, o laʻau ma laulaau o le a umi tele, o le a faʻaitiitia le malulu, ma e faigofie ona aʻafia i faʻamaʻi ma faʻamaʻi.
2. Fugalaau phosphate
(1) O lona aoga o le faʻamalosia o laʻau ma lala o laʻau, faʻaleleia le faʻavaeina ma le fuga o fuga o fuga, faʻatupu fua vave ona matutua, ma faʻaleleia le lamala ma le malulu o laʻau.
(2) Afai e leai ni phosphate i laaufetilaisa, latou te tutupu lemu, o latou lau, fugalaau ma fua e laiti, ma o latou fua ua tuai ona matutua.
3. Fetila'i matala
(1) O lana galuega o le faʻamalosia o laʻau laʻau, faʻaleleia le atinaʻeina o aʻa, faʻaleleia le faʻamaʻi o laʻau, teteʻe iniseti, teteʻe o lamala, teteʻe nofo, ma faʻaleleia le lelei o fualaau aina.
(2) Afai e le lava le faʻamaʻi o le potassium, o le a aliali mai ni mea faʻafefete i luga o laulaau o laʻau, sosoo ai ma le mago ma le necrosis.
(3) O le tele o le fa'alaisa o le potassium e o'o atu ai i le fa'apu'upu'u o totonu o la'au, fa'apu'upu'u tino o la'au, lanu samasama, ma i tulaga ogaoga, oti.
2. O le a le ituaiga fetilaisa e faiNPK fertilizere iai?
1. Faila nitrogen
(1) Nitrogen o le vaega autu nutrient o le fetilaisa, aemaise lava e aofia ai le urea, Ammonium bicarbonate, ammonia, ammonium chloride, Ammonium nitrate, ammonium sulfate, ma isi.
(2) E i ai ituaiga eseese o le nitrogen fertilizers, lea e mafai ona vaevaeina i le nitrate nitrogen fertilizer, ammonium nitrate nitrogen fertilizer, cyanamide nitrogen fertilizer, ammonia nitrogen fertilizer, ammonium nitrogen fertilizer, ma amide nitrogen fertilizer.
2. Fugalaau phosphate
O le meaʻai autu o le faʻalaʻau o le phosphorus, aemaise lava e aofia ai le Superphosphate, calcium magnesium phosphate, phosphate rock powder, meaʻai ponaivi (meaʻai ponaivi manu, meaʻai ponaivi iʻa), araisa bran, fua iʻa, Guano, ma isi.
3. Fetila'i matala
Patasa sulfate, Potassium nitrate, Potassium chloride, Wood efu, ma isi.
