Emizamweni yokondla inani labantu emhlabeni wonke elikhula ngokushesha, isidingo sezinqubo zezolimo ezisimeme sesibaluleke kakhulu kunanini ngaphambili.Izindlela zokulima zendabuko zivame ukuncika kakhulu ekusetshenzisweni kukamanyolo wamakhemikhali, ongagcini nje ngokubeka usongo endaweni ezungezile kodwa futhi okuholela ekuwohlokeni kwenhlabathi ngokuhamba kwesikhathi.Kodwa-ke, ngokwethulwa kwe-formamidine acetate, ikhemikhali eyaziwa ngezici zayo ezisebenzayo zokulungisa i-nitrogen, umkhakha wezolimo olusimeme ubhekene noguquko oluthembisayo.
I-Formamidine acetate, ngenombolo yayo ye-CAS 3473-63-0, ithole ukunakwa ngekhono layo eliyingqayizivele lokuguqula i-nitrogen yasemkhathini ibe uhlobo olusebenzisekayo lwezitshalo.I-nitrogen iyisakhamzimba esibalulekile ekukhuleni kwezitshalo, kanti nakuba yenza cishe u-78% womkhathi womhlaba, izitshalo zingawusebenzisa kuphela uma usesimweni esimisiwe.Ngokwesiko, abalimi bebethembele kumanyolo we-nitrogen wokwenziwa adinga amandla amaningi ukuze akhe futhi abe nomthelela omubi kwezemvelo lapho efakwa emanzini.Kodwa-ke, i-formamidine acetate inikeza enye indlela eqhubekayo ngokwenza izitshalo zikwazi ukufinyelela ngokuqondile i-nitrogen yasemkhathini, ukunciphisa isidingo somanyolo wamakhemikhali.
Enye yezinzuzo eziyinhloko ze-formamidine acetate kwezolimo esimeme isivuno sezitshalo esithuthukisiwe.Njengoba izitshalo zinomthombo ongashintshi we-nitrogen, zingakhula futhi zikhule ngesivinini esisheshayo.I-nitrogen iyingxenye ebalulekile yokukhiqiza amaprotheni, ama-enzyme, ne-chlorophyll, konke okubalulekile ekukhuleni kwezitshalo.Ngezakhiwo zokulungiswa kwe-nitrogen ye-formamidine acetate, izitshalo zingafinyelela amandla azo ofuzo aphelele, okuholela ekuvuneni okuphezulu kanye nekhwalithi ethuthukisiwe.
Ngaphandle kokuthuthukiswa kwesivuno,i-formamidine acetatefuthi idlala indima ebalulekile ekukhuthazeni ukumelana nezifo ezitshalweni.I-nitrogen iyisakhi esibalulekile sama-amino acid, izakhi zamaprotheni ezihilelekile ezindleleni zokuzivikela zezitshalo.Ngokuhlinzeka izitshalo ngokunikezwa okuqhubekayo kwe-nitrogen, i-formamidine acetate iqinisa isimiso somzimba sokuzivikela ezifweni, ibenza bakwazi ukugwema izifo kanye namagciwane ngokuphumelelayo.Lokhu akunciphisi nje kuphela isidingo sezibulala-zinambuzane eziyingozi kodwa futhi kufaka isandla ekusimameni okuphelele kwezinqubo zezolimo.
Ukusetshenziswa kwei-formamidine acetateinamandla okuguqula izindlela zokulima emhlabeni wonke, ukuqinisekisa ukutholakala kokudla kanye nokunciphisa umthelela wemvelo wezolimo.Ngokunciphisa ukuthembela kumanyolo we-nitrogen wokwenziwa, ukukhululwa kwamagesi abamba ukushisa nokugeleza okungcolile emanzini kungancishiswa kakhulu.Ngaphezu kwalokho, ukusetshenziswa kwe-formamidine acetate kungathuthukisa impilo yenhlabathi ngokuvimbela ukugeleza kwe-nitrogen nokugcina izakhi zayo ezinomsoco, okuholela ekuvundeni kwenhlabathi okusimeme ezizukulwaneni ezizayo.
Kubalulekile ukuqaphela ukuthi i-formamidine acetate kufanele isetshenziswe ngokuzibophezela nangokuhambisana nezinye izindlela zokulima ezisimeme.Ukujikeleziswa kwezitshalo, ukunqampuna kwekhava, kanye namasu okulawula izinambuzane kufanele kusetshenziswe kanyekanye ukuze kutholakale imiphumela emihle.Ukwengeza, ucwaningo olwengeziwe nokuthuthukiswa ekwakhiweni nasekusetshenzisweni kwe-formamidine acetate kubalulekile ukuze kuqinisekiswe ukusebenza kwayo futhi kuncishiswe noma yimiphi imiphumela emibi engaba khona.
Ekuphetheni,i-formamidine acetateunesithembiso esikhulu ekuguquleni umkhakha wezolimo olusimeme.Izici zayo zokulungisa i-nitrogen azigcini nje ngokuthuthukisa isivuno kodwa futhi zikhuthaza ukumelana nezifo ezitshalweni.Ngokunciphisa ukuthembela kumanyolo wamakhemikhali, i-formamidine acetate ingadlala indima ebalulekile ekuqinisekiseni ukuvikeleka kokudla kanye nokunciphisa umthelela wemvelo wezinqubo zezolimo.Ngocwaningo oluqhubekayo kanye nokuqaliswa okunomthwalo wemfanelo, i-formamidine acetate inamandla okuvula indlela yekusasa elisimeme nelivikelekile kwezolimo.
