Yintoni potash izichumisi zeetumato ukungena kakuhle?

Yintoni kwenziwa kunye neefom apho kukho kwipotasi yesichumiso? Ukusetyenziswa kwezi zinto kwezolimo unendima ebalulekileyo, t. To. Ipotaziyam oxide kubalulekile kuphuhliso eyiyo izityalo ezininzi. okubonakalayo ukuze kuveliswe imveliso afunyenwe phambene ngokohlobo iityuwa, kainite, sylvite, karlinita, sheinita kunye nabanye. Of kuzo besila iimveliso zoomatshini ekwanti ezilula (kainite kunye sylvinite) kunye nezinto kunye ikhemikali kuqamba ezintsonkothileyo.

Ziziphi izichumisi potash wavelisa ishishini yemichiza mihla? Oku kakhulu Potassium-wemagniziyam (potassium oxide - ukuya kwi 25-26%, nemagnesium - malunga 11-18%, aliqulathanga ichlorine) Kalimag (potassium hayidroksayidi malunga nama-24%, kananjalo akaba neklorin nokubunjwa kwayo), potassium ityuwa (combined formula sylvite kunye potassium chloride, potassium oxide - 40%, ukunyuka umxholo chlorine).

Umanyolo isichumiso zeetumato zinikwa kuqala chloride potassium kunye potassium sulfate. Eyokuqala kuzo ngumgubo crystalline emhlophe, enyibilikayo emanzini. Ipotaziyam chloride into eyenziwe sylvinite ngokuthi kususwe ubumdaka, nto leyo mxube umlinganiselo ophezulu kweziyobisi izimbiwa (ukuya kwi-62% of potassium oxide). Le nkcazelo yahlaliswa kakubi ukufunxa ukufuma, ngoko musa ukuba zixinaniswe, ukuze igcinwe seplastiki ngokulula zathuthwa umhlaba.

Umanyolo zeetumato ngohlobo potassium chloride yenziwe lingahenyuzi yeKhlorini kwemfuneko "ekhohlo" ngokwemaleko asezantsi lomhlaba yaye akufumaneki ukuba kwiingcambu zezityalo. Kodwa enye into - sulfate Potassium - abangenabo ezifana enesiqulatho neklorin ekwakhiweni amachiza, angavumeli ukuba iklasi lusetyenziswa kakhulu isichumiso okwangoku.

Iinxalenye potassium sulfate yasetyenziswa njengoko umanyolo engundoqo okanye entwasahlobo-ehlotyeni zeetumato. ukwakhiwa kwawo chemical (malunga amathathu ekhulwini magnesium, 18% isalfure, yaye malunga ne-50% potassium oxide) ukuthintela ukubuna amagqabi kwaye ufumane isivuno esihle. Isixa isichumiso ukhethe ngamnye kwimeko nganye, ngokuxhomekeke kwiimeko zemozulu, ubumuncu bomhlaba, ibakala crop, izityalo iintlobo kunye nezinye isichumiso. Umzekelo, umgquba (group nitrogen) kunciphisa ukwanela ukufunxeka izichumisi potassium. Ilusini watyala phambi iitumato, thatha elininzi potassium emhlabeni nezityalo, phezu koko, ayikho ingqalelo le nto.

Ukuze umanyolo izichumisi zeetumato baba luncedo kakhulu, kubalulekile ukubala amazinga isicelo. Ukuza kuthi ga ngoku, kungakuhle ukuba ukwazi njani potassium eninzi eziqulathwe emhlabeni (isifundo zinoku-odolwa bokuba ezizodwa). Ngoko kuyimfuneko ukumisela umyalelo, ubuninzi ukwimo ecocekileyo kufuneka olu hlobo (nithi 20 iigrem potassium square metre nganye), kwaye mazibale imali efunekayo isichumiso. Kwimeko yethu, ukuze isityalo efunyenweyo 20 grams. potassium kuyimfuneko ukuba, umzekelo, 40 iigrem potassium sulfate, okt. k. Nguye kuphela isiqingatha iqulathe oxide efunekayo us element. A indlela elula, kodwa oluchanekileyo kangako ukufumanisa eqhelekileyo kukuba ulandele izikhokelo diphu uhlobo oluthile isichumiso.
