Calcium nitrate: isici futhi isicelo endaweni

Calcium nitrate (calcium nitrate) kuyinto crystalline, emhlophe kakhulu kwakwakhe okuqinile, esingeyena iphunga.

Ingqikithi kuyinto hygroscopic kakhulu futhi kalula ancibilikisa emanzini. Kufanele kuqashelwe ukuthi i-calcium nitrate kusheshe crystallize. Lokhu kuveza izinhlobo ezintathu hydrates crystalline. Kuvele ethile ebalulekile eka- ikhekhe. Lokhu kufanele kunakwe isitoreji efanele. Ngakho, kufanele calcium nitrate elondolozwe ku ekhethekile amaphakheji uphawu (polypropylene izikhwama).

Kufanele kuphawulwe ukuthi ngaphansi kwezimo ezivamile le fire- lemagalagala ukuqhuma-ubufakazi, okungezona ezivuthayo oqine ku uhla -60 - +155 ° C, kodwa lapho esebenzelana nabo kufanele usebenzise izingubo ezivikelayo izembatho zokuzivikela.

Calcium nitrate: isicelo

Ukwakheka kufaka calcium nitrate 15% i-nitrogen ne-26% of Cao, okuvumela ukusetshenziswa kwayo kabanzi kwezolimo ukugcwalisa ukushoda izakhi idatha emhlabathini, kanye isitshalo umsoco.

Esanele nitrogen lokuhlushwa kuyadingeka zokuthuthukisa leaf mass, synthesis amino acid, amaprotheni kanye chlorophyll. Calcium unesibopho ukwakheka kwamaseli amasha, kuqinisa umzimba kanye izimpande zezitshalo. Ngenxa yalokhu, i-calcium nitrate asetshenziswe yellowing amaqabunga kanye coagulation yabo ringlet, ukubukeka iphuzu necrosis ngesimo round izindawo elincane umbala konsundu, futhi lapho ebuthaka uhlelo impande, uphelela abolile izitshalo futhi ekunqandeni ukukhula. Ngaphezu kwalokho, ukusetshenziswa Umanyolo kuvimbela ukuthuthukiswa kwe-bola apical e utamatisi, kanye ukusha ulethisi. Kufanele kuphawulwe ukuthi i-calcium nitrate lapho ifakwe enhlabathini acid aqede lokuhlushwa ngokweqile yensimbi manganese.

Calcium nitrate isetshenziswa ngendlela liquid noma impande isicelo foliar. Lokhu kungase kusetshenziswe drip irrigation eyenzeka, ukufakwa ekhethekile, hose, moya noma knapsack sprayers. Kufanele ukuthi izinga yesixazululo zokusebenza kwe-calcium nitrate kuyinto ezivamile futhi kuncike hlobo sigqoka nezitshalo.

Kufanele kuphawulwe ukuthi i-calcium nitrate kuyinto bokuphila ane-alikhali Umanyolo, ngakho-ke ingasetshenziswa zonke izinhlobo zenhlabathi. Ngeke kuhlangene superphosphate elula, kodwa nabanye umquba calcium nitrate ovunyelwe ukuhlanganisa ngokushesha ngaphambi ukusebenzisa. Ngemva komsebenzi, geza izandla kanye nobuso ngensipho namanzi.

Mangisho ukuthi nitrate calcium isetshenziswa hhayi kuphela njengoba nomanyolo for izitshalo. Kuyinto futhi okufakiwe for ukhonkolo, okuvumela ukuba ukwandisa ngamandla alo. Ngaphezu kwalokho, lokhu kwakwakhe kuvimbela ukugqwala ukuqinisa ivikela zokwakha nokusondelana okushisa aphansi lisetshenziswe ukukhiqizwa amafriji brine, reagents ahlukahlukene ne-fiberglass, kanye eqakathekileko iziqhumane.
