Kwinqanaba lokuqala lokunqongophala kwe-potassium,isityalo sengcas zibonisa ukukhula kancinci kunye namagqabi aluhlaza okwesibhakabhaka. Iimpawu eziphambili zokunqongophala kwe-potassium: ngokuqhelekileyo amagqabi amadala kunye nemiphetho yamagqabi iba mthubi kuqala, emva koko ibe mdaka, itshiswe kwaye itshiswe, kwaye kuvela amabala amdaka kunye namabala amdaka kumagqabi, kodwa embindini, imithambo kunye neendawo ezikufutshane nemithambo zihlala ziluhlaza. Njengoko izinga lokunqongophala kwe-potassium likhula, lonke igqabi liba mdaka okanye lome, liyafa kwaye liwe; amanye amagqabi esityalo anombala webronze, agobile ezantsi, kunye nezicubu ze-mesophyll ezivuthulukileyo kumphezulu wegqabi kunye nemithambo etshonileyo. Xa izityalo zingena-potassium ngokwaneleyo, inkqubo yeengcambu nayo yonakele kakhulu, ineengcambu ezimfutshane nezimbalwa, ezilungele ukuguga ngaphambi kwexesha, zibola kwiimeko ezinzima, kwaye zihlala kwindawo yeengcambu. Xa izityalo zengca zingena-potassium ngokwaneleyo, kuvela amabala amdaka kumagqabi asezantsi, kwaye kwiimeko ezinzima, iimpawu ezifanayo zivela kumagqabi amatsha. Amagqabi athambile kwaye ayawa, iziqu zincinci kwaye zibuthathaka, kwaye ii-internodes zimfutshane; xa izityalo ze-leguminous zingena-potassium ngokwaneleyo, uluhlaza oluphakathi kwemithambo luya kuqala luvele, emva koko lube mthubi, lwenze amagqabi anamabala. Kwiimeko ezinzima, imiphetho yamagqabi iya kutsha ize igobe iye ezantsi, kwaye amabala amdaka aya kuvela ngaphakathi kwindawo ephakathi kwemithambo. I-epidermis yamagqabi ilahlekelwa ngamanzi kwaye iyancipha, umphezulu wamagqabi uyajika okanye ugobe, kwaye kancinci kancinci uyatsha aze awe, kwaye isityalo siyaguga ngaphambi kwexesha.
Ndingenza ntoni ukuba ingca ayinayo i-potassium? I-Potassium ayisiyongondlo ibalulekileyo kuphela kubomi bezityalo, kodwa ikwayenye yezinto ezintathu zesichumisi. Umxholo we-potassium kwizityalo ulandela i-nitrogen kuphela. Ukusetyenziswa ngokufanelekileyo kwesichumisi se-potassium kunokuphucula i-photosynthesis yezityalo zengca kunye nokumelana kwazo nezifo kunye nezinambuzane. Ukuba iimpawu zokunqongophala kwe-potassium zifunyenwe kulawulo lwengca, isichumisi se-potassium (esifana ne-potassium chloride, i-potassium sulfate, i-potassium phosphate, njl.njl.) kufuneka sisetyenziswe ukuthintela nokulawula. I-Potassium chloride kunye ne-potassium sulfate zombini zizichumisi ezisebenza ngokukhawuleza ezinokusetyenziswa njengesichumisi esisisiseko kunyeukunxiba ngaphezuluKungcono ukusebenzisa i-potassium sulfate kumhlaba one-asidi kunye ne-potassium nitrate kumhlaba one-alkaline.
Ukuba ingca inezi mpawu zingasentla, ezi ndlela zilandelayo zingasetyenziswa ukujongana nayo:
1. Faka isichumisi senitrogen esincinci uze usinkcenkceshele kwangoko emva kokufaka isichumisi senitrogen.
2. Sebenzisa iimveliso zeengcambu ezinee-amino acids kunye nee-trace elements ukutshiza, ikakhulu ekuvuseleleni iingcambu kunye nokongezelela ii-trace elements.
3. Faka i-potassium sulfate 2kg/ngexesha.
