I-potassium nitrate, okubunjwa kwayo kuhlanganisa i-potassium ne-nitrogen, ingenye yamanyolo ama-potassium athandwa kakhulu. Kuhle ngoba, uma kuqhathaniswa namanye amakhemikhali ayenziwe nge-potassium, okungenani kuyingozi emhlabathini. I-nitassium nitrate inesicelo esikhulu kakhulu, ikakhulukazi kuyadingeka izitshalo zezimbali. Kumele kuqashelwe ukuthi izindawo zayo eziwusizo ziye zaphawulwa isikhathi eside, futhi lapho kungekho ukukhiqizwa kwamakhemikhali, abalimi benza izitrate ngokwabo, baxuba umlotha nomquba.
Isenzo
Umbuzo wokuqala esizoxoxa ngawo yilokho okudingekayo nge-potassium nitrate. I-potassium ne-nitrogen yizinto ezimbili ezidingekayo kunoma yisiphi isitshalo. Ngokuvamile, i-nitrogen inomthelela omkhulu ekuthuthukiseni umthamo ohlaza okwesibhakabhaka, futhi i-potassium iyadingeka ukuze kube nezimbali eziningi nezimbali. I-potassium nitrate iqukethe kokubili izinto, futhi ithinta kahle isitshalo kusukela ezinsukwini zokuqala zokuphila. Okokuqala, amandla okulwela izimpande athuthukisa, okungukuthi, isitshalo "sondla" singcono - futhi lokhu kuyisihluthulelo sokuvuna okuhle. Ngaphezu kwalokho, lesi sitshalo sithuthukiswe ukuphefumula kanye nenqubo ye-photosynthesis, okuholela ekuthuthukiseni isitshalo sonke, kuyilapho izicubu zinesakhiwo esinamandla, esingaphansi kwezifo.
Isicelo
I-potassium nitrate ngumanyolo osetshenziselwa kokubili njengokuyisisekelo kanye nokugqoka amafutha. Njengazo zonke izidakamizwa ezine-nitrogen, kungcono ukuyenza enhlabathini entwasahlobo, ekuqaleni kokukhula kwezitshalo, ngesilinganiso sama-gramu angu-20 kumitha wendawo ngayinye. Uma usebenzisa elinye i-potassium nitrate (i- ammonium nitrate , i- carbamide , njll) ngaphandle kwe-nitrate ye-potassium, ubuningi babo bungcono ukunciphisa - ukudlula ngisho nemithi ewusizo kakhulu kungaholela ekuthuthukiseni okungalungile kwesitshalo.
Ngaphezu kwalokho, i-potassium nitrate ifakwa ngendlela yokufaka umquba, ikakhulukazi kusukela ngesikhathi sokubukeka kweziqu bese kuphelelwa ukuvuthwa kwesithelo. Inani le-nitrogen kulo liyingcosana, ngakho-ke izitshalo ezithela izithelo lokhu kuyindlela enhle yomanyolo. Khumbula ukuthi kusuka kwamanye umanyolo we-nitrogen oqukethe isikhathi sokusila, kungcono ukwenqaba. Ukutshala amagremu ama-25 e-saltpeter akhiwe ngamalitha angu-10 amanzi, ukuchelela kwenziwa njalo ezinsukwini ezingu-10 noma ezingu-15, kuye ngokuthi inhlabathi nesimo sesitshalo. Uma kunesidingo se-potassium - isibonelo, amaqabunga amancane akhiwa noma i-ovary ikhula kabi - khona-ke kungenzeka ukuba ugqoke ama-foliar phezulu kusuka ku-nitrate ye-nitrate. Ngenxa yalokhu, ukuhlushwa kufanele kube kancane kancane - ama-gram angu-25 ngamalitha ayi-15, ngaphandle kwalokho kukhona ingozi yokushisa amaqabunga. Lelixazululo kumele lifakwe ngesitshalo, kungcono ukuyikhiqiza kusihlwa noma ekuseni, lapho kungekho ilanga, esesimweni esomile, esingenamoya.
I-potassium nitrate ingumanyolo owenza i-flowering and fruiting, ngakho-ke akunakwenzeka ukuyisebenzisa izimpande zezitshalo nezinye izitshalo ezibiza izingxenye zemifino. Kulesi simo, kwanele ukwengeza u-saltpeter entwasahlobo enhlabathini, nokufaka umanyolo wokufaka umquba wokufaka umquba omanyolo onomuthi ophezulu we-nitrogen nokunciphisa i-potassium, ngaphandle kwalokho amazambane akho angaba umbhede wembali.
Izinyathelo zokuphepha
I-nitassium nitrate iyi-oxidizer, iphendula ngokushesha ngezinsimbi ezihlukahlukene zokuncipha kanye nezinto ezinokushisa, ngakho-ke
Inqubo yokusebenzisa i-potassium nitrate ubuchwepheshe bokuphepha bufana nanoma imuphi umuthi wamakhemikhali. Amaglovu enqabile - ayisebenzise kuphela izitsha ezingezona ukudla, futhi ngokugqoka okuphezulu kwe-foliar kuyoba usizo ukuvikela iphefumula ngokuphefumula.
