Ukusetshenziswa kwe-calcium nitrite kwezolimo

Izithako zomanyolo

 

I-calcium nitrite ingasetshenziswa njengesithako somanyolo ukunikeza izakhi ezidingekayo ze-nitrogen ne-calcium ezitshalweni. I-nitrogen ingenye yezinto ezibalulekile ekukhuleni kwezitshalo, kuyilapho i-calcium ibalulekile ekwakheni izindonga zamangqamuzana ezitshalo kanye nokuxhumana phakathi kwamangqamuzana. Ngokusebenzisa okunengqondo, i-calcium nitrite ingasiza ukuthuthukisa isivuno sezitshalo kanye nekhwalithi.

 

Ukuchitshiyelwa komhlabathi

 

I-calcium nitrite ingasebenza futhi njengesichibiyelo senhlabathi, isize ukuthuthukisa ukwakheka kwenhlabathi futhi ithuthukise umthamo wokugcina amanzi enhlabathini. Ezindaweni ezinokwakheka kwenhlabathi okungekuhle noma ukuntuleka kwemisoco edingekayo, ukusetshenziswa kwe-calcium nitrite kungathuthukisa ukuvunda komhlabathi futhi kukhuthaze ukukhula kwezitshalo.

 

umgqugquzeli wokukhula kwezitshalo

 

I-nitrite ion (NO2-) ku-calcium nitrite ingakhulula i-nitric oxide (NO) ngaphansi kwezimo ezithile, okuyisilawuli esibalulekile sokukhula kwezitshalo. Kungakhuthaza i-photosynthesis nokuphefumula kwezitshalo, futhi kuthuthukise ukumelana kwazo nezifo.

 

Ama-preservatives ekugcinweni nasekuhambeni

 

Kwezinye izimo, i-calcium nitrite ingasetshenziswa njengesilondolozi semikhiqizo yezolimo ngesikhathi sokugcinwa nokuhamba. Isibonelo, ekulondolozweni kwezithelo nemifino ethile, i-calcium nitrite inganciphisa inqubo ye-oxidation futhi yandise isikhathi sokugcina.

 

Ama-insecticides nama-fungicides

 

I-calcium nitrite nayo inezinga elithile lemiphumela ye-insecticidal kanye ne-bactericidal. Kweminye imikhuba yezolimo ephilayo noma enobuthi obuphansi, i-calcium nitrite ingasetshenziswa njengesibulala-zinambuzane esingokwemvelo noma esinobuthi obuphansi kanye nesibulala-sikhunta ukusiza ukulawula izinambuzane nezifo.

 

Ukucatshangelwa kokuphepha kanye nemvelo

 

Nakuba i-calcium nitrite inemisebenzi eminingi kwezolimo, ukusetshenziswa kwayo kufanele kuqaphe kakhulu njengoba inobuthi obuthile. Lapho usebenzisa i-calcium nitrite, kuyadingeka ukulandela umthamo ofanele kanye nendlela yokugwema ukulimala emvelweni nempilo yabantu. Ngaphezu kwalokho, ukusetshenziswa kwe-calcium nitrite kufanele futhi kuhambisane nemithetho yendawo yezolimo neyemvelo.

 

isiphetho

 

Ukusetshenziswa kwe-calcium nitrite kwezolimo kugxilwa kakhulu njengesithako somanyolo, ukuchitshiyelwa kwenhlabathi, umgqugquzeli wokukhula kwezitshalo, isivikelo, futhi kwezinye izimo, njengesibulala-zinambuzane nesibulala-sikhunta. Ngokusetshenziswa okunengqondo, i-calcium nitrite ingakhuphula isivuno nekhwalithi yezitshalo, ithuthukise ukwakheka kwenhlabathi, futhi yandise isikhathi sokugcinwa kwemikhiqizo yezolimo. Kodwa-ke, ngenxa yobuthi obungase bube khona, ukusetshenziswa kwe-calcium nitrite kudinga ukunamathela ngokuqinile emithethweni yokuphepha ukuze kuqinisekiswe ukuthi ayinayo imithelela emibi emvelweni nempilo yabantu. Ngokuthuthuka kobuchwepheshe bezolimo, kuzoba nocwaningo olunzulu kanye nokulawulwa okuqinile kokusetshenziswa kwamakhemikhali afana ne-calcium nitrite kwezolimo.
