Emkhakheni okhulayo wamakhemikhali ezolimo nawezimboni, i-ammonium sulfate igqama futhi idlala indima ebalulekile. Ikakhulukazi, indima yeShayina ekukhiqizeni nasekudayiseni lo sawoti wezinto ezingaphili kunemithelela ebalulekile ezimbonini ezahlukahlukene. Ngezakhiwo zayo zamakhemikhali eziyingqayizivele kanye nezicelo zokuhweba, i-ammonium sulfate ingaphezu nje komanyolo; Iyisisekelo sezolimo nezimboni zesimanje.
Funda nge-ammonium sulfate
I-ammonium sulfate, ngokwesayensi imelelwe ngokuthi (NH4)2SO4, usawoti wezinto ezingaphili onothile wezinzuzo. Iqukethe u-21% we-nitrogen kanye no-24% wesulfure, ingumanyolo omuhle kakhulu wenhlabathi owandisa isivuno nekhwalithi yezitshalo. Amazinga e-nitrogen akhuthaza ukukhula kwezitshalo okunempilo, kanti isulfure ibalulekile kuma-amino acid kanye nokuhlanganiswa kwamaprotheni. Lokhu kusebenza okumbaxambili kwenza i-ammonium sulfate ibe yinketho yokuqala phakathi kwabalimi nochwepheshe bezolimo.
I-China iphethe ukukhiqizwa kwe-ammonium sulfate
Ngezinsiza zayo eziningi namandla okukhiqiza athuthukile, iChina isibe umholi womhlaba wonke ekukhiqizeni i-ammonium sulfate. Ukutshalwa kwezimali kwamasu kweShayina ezikhungweni zokukhiqiza amakhemikhali kuyenza ikwazi ukuhlangabezana ngokuphumelelayo nesidingo sasekhaya nesamazwe ngamazwe. Ngakho-ke,I-ammonium sulfate yaseChinaayigcini nje ngokuba nenani elincintisanayo kodwa futhi ihambisana nezindinganiso zekhwalithi ephezulu, okuyenza ibe ukukhetha okuthembekile emabhizinisini omhlaba.
Imboni yaseShayina i-ammonium sulfate ibonakala ngochungechunge oluqinile lokuhlinzeka kusuka ekuthengeni impahla eluhlaza kuya ekusatshalalisweni. Lokhu kusebenza kahle kwenza ukulethwa ngesikhathi kanye nokutholakala komkhiqizo okungaguquki, okubalulekile emjikelezweni wezolimo. Ukwengeza, ukuzibophezela kwezwe ekusunguleni nasekusimameni ekukhiqizweni kwamakhemikhali kugqugquzele ukuthuthukiswa kwezinqubo zokukhiqiza ezihambisana nemvelo, okuqhubekisela phambili ukukhanga kwayo ezimakethe zomhlaba.
Iqhaza lethimba labadayisi abaqeqeshiwe
Umnyombo walo mkhakha odlondlobalayo yithimba labadayisi elinochwepheshe elineminyaka engaphezu kwe-10 yokuhlangenwe nakho kwebhizinisi lokungenisa nokuthekelisa. Amalungu eqembu lethu ngaphambilini asebenzele abakhiqizi abakhulu, ebanikeza ukuqonda okujulile kwezidingo zamakhasimende kanye namandla emakethe. Lobu buchwepheshe busivumela ukuthi sinikeze izixazululo ezenziwe ngomthungo ezihlangabezana nezidingo ezithile zamakhasimende ethu, kungakhathaliseki ukuthi abalimi abafuna umanyolo osebenzayo noma amabhizinisi ezimboni afuna izinto ezithembekile zamakhemikhali.
Ithimba lethu labadayisi elichwepheshile linekhono lokuzulazula ezinkingeni zohwebo lwamazwe ngamazwe, liqinisekisa ukuthi amakhasimende ethu awatholi nje kuphela i-ammonium sulfate yekhwalithi ephezulu, kodwa futhi nenkonzo enhle kakhulu. Sibeka phambili ukwakha ubudlelwano besikhathi eside namakhasimende ethu, sazi ukuthi ukwethembana nokwethembeka kubalulekile embonini yamakhemikhali.
Ikusasa lemboni ye-ammonium sulfate
Njengoba izindlela zezolimo zithuthuka emhlabeni jikelele, isidingo somanyolo osebenzayo njengeumanyolo we-china ammonium sulfatekulindeleke ukuthi ikhule. Njengoba ukuqwashisa ngezinqubo zokulima ezisimeme kuqhubeka kukhula, ukugcizelelwa kokusebenzisa umanyolo osezingeni eliphezulu, ongangeni ndawo kuzokhula kuphela. Ngobuchwepheshe obuthuthukisiwe bokukhiqiza nokuzibophezela kwikhwalithi, imboni yaseShayina ye-ammonium sulfate isesimweni esihle sokuhlangabezana nalesi sidingo.
Ukwengeza, ukuguquguquka kwe-ammonium sulfate kudlulela ngalé kwezolimo. Ibuye isetshenziselwe izinhlelo ezahlukene zezimboni, okuhlanganisa ukwelashwa kwamanzi, ukucubungula ukudla kanye nemithi. Lolu hlu olubanzi lokusetshenziswa luqinisekisa ukuthi isidingo se-ammonium sulfate sizohlala siqinile, silolonge imboni iminyaka ezayo.
Ekuphetheni
Sekukonke, ukukhiqizwa kwe-ammonium sulfate yaseChina kungamandla abalulekile emakethe yomhlaba wonke, eqhutshwa izinga, ukusebenza kahle kanye nokuqonda okujulile kwezidingo zamakhasimende. Sinethimba labadayisi elichwepheshile elizinikele ekunikezeni isevisi enhle kakhulu futhi lizibophezele ekuhlinzekeni ngekhwalithi ephezulu ye-ammonium sulfate emikhakheni yezolimo neyezimboni. Uma sibheka phambili, indima ye-ammonium sulfate ekulolongeni imboni izoqhubeka nokukhula, okuyenza ibe yingxenye ebalulekile yentuthuko esimeme kanye nempumelelo yezolimo.
