Ukunikezwa ngokweqile kwe-nitrogen kuvimbela ukukhula kwezitshalo futhi kukhiqiza ubuthi obunobuthi be-nitrite
Umanyolo we-nitrogen ngumanyolo wamakhemikhali odingakalayo kakhulu ekukhiqizweni kwezolimo, okubamba iqhaza elibalulekile ekukhuliseni isivuno sokwengeza kanye nokwenza ngcono ikhwalithi yemikhiqizo yezolimo. Kodwa-ke, uma ukuhlinzekwa kukhulu kakhulu, kuzokwenza izilimo eziluhlaza okwesibhakabhaka zikhule sekwephuze isikhathi, isikhathi sokukhula isikhathi eside, ikakhulukazi ezindongeni zeseli elincane, izitshalo ezithambile, ezisengozini) nokuhlaselwa kwezifo (ikhanda likakolweni I-Blight, iRice Brown Spot). Ngasikhathi sinye, ukusebenzisa inani elikhulu lomanyolo we-nitrogen kungenza nekotini futhi i-boll indlala futhi kube lula ukuwa, izinga lokukhiqiza ushukela likashukela we-beet izimpande ukwehla, ukuncipha kwekhwalithi yefayibha.
Ukunakwa okukhethekile kufanele kukhokhwe kulowo manyolo we-nitrogen owedlulele kukhiqize imifino "n", into edliwayo, njengeqabunga le-stem yalo kwakungukungcola kwalo kwemifino kukhulisiwe, bese kuguqulwa ku-nitrite, futhi i-nitrite inobuthi kakhulu Izinto, kungadala umzimba womzimba we-hypoxia, futhi kungadala umdlavuza, ukulimala okukhulu.
Isicelo se-phosphorus ngokweqile siphumela ku-chlorosis yezilimo ezingenakuphikwa inhlabathi
Ukusetshenziswa kwe-superphosphate ejwayelekile akukwazi ukuhlinzeka ngokudla kwe-phosphorus kwezilimo, kepha futhi yenza izilimo zithole umsoco we-sulfur. Kepha ngenxa yokuqukethwe kwayo okuphansi kwe-phosphorus kanye nezakhi eziningi, i-superphosphate esindayo isetshenziswa kakhulu ekukhiqizweni komanyolo we-phosphate. I-superphosphate esindayo ayinayo ukungcola efana ne-calcium sulfate, ukuze okuqukethwe kwe-phosphorus kukhuphuke kakhulu, kube ukugcwala okuphezulu komanyolo we-phosphate. Ngakho-ke, ukusetshenziswa kwe-perennial kwe-superphosphate esindayo kuzoholela ekushoneni kwesibabule.
Izimpawu zokuntulwa kwezilimo ze-sulfur kanye nokuntuleka kwe-nitrogen kufana kakhulu, isici esiyinhloko siyiqabunga le-chlorobis, kodwa kusuka kwinkulumo ecashile, zihlukile. Izimpawu zokuntuleka kwe-nitrogen ziqala kuqala kusuka emaqabungeni amadala aphansi, kanti izimpawu zokuntuleka kwesibabule ziqala emaqabunga amasha aphezulu, okuholela emaqabunga aluhlaza aphuzi.
Ngakho-ke, ukuze kuncishiswe ukuvela kwenhlabathi ukuntuleka kwenhlabathi, i-superphosphate ejwayelekile kufanele ikhethwe lapho kutshalwa izilimo ezithanda izibulfur, noma okunye ukusetshenziswa kwe-superphosphate ejwayelekile ne-superphosphate esindayo kufanele kwamukelwe.
Ukunikeza i-potassium eyeqile kuthinta ukukhula kwezitshalo futhi kubhubhise ukwakheka kwenhlabathi
Umanyolo we-potassium uluhlobo lomanyolo wokukhula kwezitshalo. Ukusetshenziswa okufanele komanyolo we-potassium kungaphonsa okusanhlamvu, ukukhulisa izimpande zamazambane namazambane, kukhuphule okuqukethwe koshukela, ukolweni nezinye izitshalo, zenza izitshalo zithambekele ekufakweni, futhi zithuthukise ukumelana nesomiso, Ukuphikiswa okubandayo nokumelana nezifo.
Umanyolo we-potassium uluhlobo lomanyolo wokukhula kwezitshalo. Ukusetshenziswa okufanele komanyolo we-potassium kungaphonsa ukusanhlamvu nokukhuthaza ukukhula kwamazambane, amazambane nezinye izimpande
Yize umanyolo we-potassium unezinzuzo eziningi, kepha hhayi okungcono kakhulu, uhlelo lokusebenza oluningi luzoletha imiphumela emibi ezitshalweni: Ukusetshenziswa ngokweqile komanyolo we-potassium kuzodala ukwehla kwezitshalo ze-magnesium, okubangela ukuvela kwemifino yeqabunga "ukubola Isifo senhliziyo ", i-Apple" Pox ebabayo "nezinye izifo; Ukusetshenziswa ngokweqile komanyolo we-potassium kuzophinde kuvinjelwe ukukhula kwezilimo, okuholele ekutheni isivuno esithambekele endaweni yokuhlala nezinye izimpawu; Ukusetshenziswa ngokweqile komanyolo we-potassium kuzodala izinsimbi ezilimazayo namagciwane kwezinye iziza, kuchithe isakhiwo senhlabathi kanye nokulinganisela, futhi kuholele ekuwohlokeni kwezakhiwo zenhlabathi nokungcoliswa komhlaba. Ukusetshenziswa ngokweqile komanyolo we-potash kuzophinde kunciphise ukukhiqizwa kwezilimo, kwenze buthaka kanzima umthamo wokukhiqiza wezitshalo, unciphise isivuno.
