Okokuqala, esimweni esinjalo, ungakweluleka ukuthi ungajahi. Ezinyangeni eziyisithupha ezichithwe ngaphansi kweqhwa, utshani buyafa - lokhu kuyinto ejwayelekile. Vele, emazweni ase-Yurobhu, i-USA neCanada, lapho isimo sezulu singesihle kangako, utshani bungathokozisa abanini ngamakhambi amasha unyaka wonke. Kepha uma iqhwa lihlala izinyanga eziyisithupha, nomhlaba uqiniswe yingxenye yemitha, akufanele uthembe ukuthi utshani lwentwasahlobo buzohluka ngobuhle.
Njengoba umkhuba ukhombisa, ngaphansi kwengqimba yeqhwa, ngokuya ngesikhathi sobusika kanye namazinga okushisa aphansi kakhulu, u-45 kuya ku-90% wotshani uyafa. Kepha lokhu akusho ukuthi uhlelo lwezimpande luyafa. Ngakho-ke, kufanelekile ukulinda kuze kufike ekugcineni iqhwa linyamalale, umhlaba uyoma kancane bese ufudumala. Cishe ngokuqinisekile, iningi lezimpande lizophila futhi linikeze amahlumela amasha. Maphakathi noMeyi - maphakathi noJuni (kuya ngesimo sezulu kanye nesifunda) utshani buzophola ngokuphelele. Utshani obabulala ebusika kufanele bususwe - kungcono ukusebenzisa i-fan fan noma umshanelo ngalokhu. Kepha okokuqala, linda utshani bome kancane emanzini ancibilikile. Ngaphandle kwalokho, imidwebo yezinyawo izosala ingaphezulu kwayo.
Vele, ungakhohlwa ngokugqoka. Ukwazi ukufaka umanyolo utshani nge-ammonium nitrate ngemuva kobusika, ungasiza utshani ngokushesha ukuba buhle.
Sifaka umanyolo ngokufanele
Uma ufuna umanyolo ofanele utshani, khona-ke ukuxuba kwe-nitrogen kuzoba yisinqumo esihle kusukela ngasekupheleni kwentwasahlobo kuya maphakathi nehlobo. Ngemuva kwakho konke, yi-nitrogen edingeka ngokuyinhloko utshani ukuze ibuyise inqwaba eluhlaza ngokushesha futhi ilondoloze ukubukeka okuhle ngisho nangokucheba okuvamile.
Omunye wabahlinzeki main of nitrogen kungaba ammonium nitrate. Okuqukethwe yi-nitrogen kuyo kufinyelela kuma-35%. Ngakho-ke, ngemuva kwezinsuku ezingama-7-10 ngemuva kokufaka ingxube enhlabathini, ngeke uwubone utshani bakho.
Ukugqoka kokuqala kungenziwa ekupheleni kuka-Ephreli, lapho umhlaba usufudumele ngokuphelele futhi womile, futhi notshani buyonikeza amahlumela okuqala. Into ebaluleke kakhulu lapha, njengokusetshenziswa kwanoma imuphi umanyolo wamakhemikhali, umthamo ofanele. Yebo, umquba we-nitrogen ulungele utshani. Kepha akufanele uthathe umthetho wokuthi "awukwazi ukonakalisa iphalishi ngebhotela." I-nitrogen engaphezulu ingashisa utshani, ikunikeze inkathazo enkulu yokuyibuyisela.
Inani elifanelekile le-ammonium nitrate limayelana nama-gramu angama-30- 40 nge-skwele ngasinye. Ungathola kabanzi ngokuthe ngqo emiyalweni eselebula. Kungcono ukuthi uzihlomise ngezikali eziqondile ukuze ungenzi iphutha ngengxenye. Ungasabalalisa umanyolo ngesandla, kodwa ukwenze ngokucophelela, futhi ngemuva kokuba inqubo isiqediwe, geza izandla zakho kahle.
Masinyane ngemuva kokusabalalisa umanyolo, kungakuhle ukuthi unisele kahle utshani ukuze inhlabathi ibe manzi futhi ibambe ngokushesha i-saltpeter.
Kungcono ukuphinda inqubo njalo ngenyanga kuze kube maphakathi no-Agasti. Ngalesi sikhathi, ukukhetha kufanele kunikezwe kumanyolo we-phosphorus ukuqinisa uhlelo lwezimpande, ukuqinisekisa ukuthi utshani obunotshani businda kalula ebusika futhi abadingi ukuhlwanyela imbewu entwasahlobo.
Kodwa-ke, i-saltpeter nayo kumele isetshenziswe ngokucophelela - i-acidity yenhlabathi inyuka kancane ngemuva kokufaka isicelo. Emhlabathini ongathathi hlangothi ne-alkaline akusiyo ingozi, kepha kulabo abane-acidity ephezulu kungadala isifo sezitshalo.
