Ezigabeni zokuqala zokuntuleka kwe-potassium,isitshalo sotshanis zibonisa ukukhula kancane kanye namaqabunga aluhlaza okotshani. Izici eziyinhloko zokuntuleka kwe-potassium: ngokuvamile amaqabunga amadala kanye nemiphetho yamaqabunga kuba phuzi kuqala, bese kuba nsundu, kushiswe futhi kushiswe, bese kuvela amabala ansundu namabala amaqabunga, kodwa phakathi, imithambo kanye nezindawo eziseduze nemithambo zihlala ziluhlaza. Njengoba izinga lokuntuleka kwe-potassium landa, lonke iqabunga liba nsundu noma lome, liyafa bese liwa; amanye amaqabunga ezitshalo anombala wethusi, agobe phansi, anezicubu ze-mesophyll ezivuvukele ebusweni beqabunga kanye nemithambo ecwile. Lapho izitshalo zintula i-potassium, uhlelo lwezimpande nalo lonakaliswe kakhulu, lunezimpande ezimfushane nezimbalwa, luthambekele ekugugeni ngaphambi kwesikhathi, lubola ezimweni ezimbi kakhulu, futhi luhlala endaweni yezimpande. Lapho izitshalo zotshani zintula i-potassium, kuvela amabala ansundu emaqabunga angezansi, futhi ezimweni ezimbi kakhulu, kuvela izimpawu ezifanayo emaqabunga amasha. Amaqabunga athambile futhi ayagoba, iziqu zincane futhi zibuthakathaka, kanti ama-internode amafushane; lapho izitshalo ze-leguminous zintula i-potassium, uhlaza oluphakathi kwemithambo luzoqala luvele, bese luphenduka luphuzi, lwakhe amaqabunga anamabala. Ezimweni ezimbi kakhulu, imiphetho yamaqabunga izosha futhi igobe phansi, futhi amabala ansundu azokhula ngaphakathi esikhaleni esiphakathi kwemithambo. Isikhumba samaqabunga silahlekelwa amanzi futhi sinciphe, ubuso bamaqabunga bugobe noma bugobe, futhi kancane kancane bushise futhi buwe, futhi isitshalo siguga ngaphambi kwesikhathi.
Yini okufanele ngiyenze uma utshani lungenayo i-potassium? I-Potassium akuyona nje kuphela isakhi esibalulekile empilweni yezitshalo, kodwa futhi ingenye yezinto ezintathu zomanyolo. Okuqukethwe kwe-potassium ezitshalweni kungokwesibili ngemuva kwe-nitrogen. Ukusetshenziswa okunengqondo komanyolo we-potassium kungathuthukisa i-photosynthesis yezitshalo zotshani kanye nokumelana kwazo nezifo nezinambuzane. Uma izimpawu zokuntuleka kwe-potassium zitholakala ekuphathweni kotshani, umanyolo we-potassium (njenge-potassium chloride, i-potassium sulfate, i-potassium phosphate, njll.) kufanele usetshenziswe ukuvimbela nokulawula. I-Potassium chloride kanye ne-potassium sulfate zombili ziyizimanyolo ezisebenza ngokushesha ezingasetshenziswa njengomanyolo oyisisekelo kanyeukugqoka phezuluKungcono ukusebenzisa i-potassium sulfate enhlabathini ene-acidic kanye ne-potassium nitrate enhlabathini ene-alkaline.
Uma utshani bunezimpawu ezingenhla, izindlela ezilandelayo zingasetshenziswa ukubhekana nalo:
1. Faka umanyolo we-nitrogen omncane bese unisela ngokushesha ngemva kokufaka umanyolo we-nitrogen.
2. Sebenzisa imikhiqizo yezimpande enama-amino acid kanye nezinto ezincane ukuze ufafaze, ikakhulukazi ukuvuselela izimpande kanye nokwengeza izinto ezincane.
3. Faka i-potassium sulfate 2kg/ngesikhathi.
