I-Manganese yensimu

U-Ogorodniki onolwazi owaziyo - emzabalazweni wokuvuna kule nkambo cishe cishe yisiphi isikhali. Isibonelo, etholakalayo kunoma yikuphi ikhabhinethi yemithi, iodine, zelenka kanye nama-manganese. Sizokhuluma ngezindlela zokusebenzisa i-potassium permanganate ensimini yemifino namuhla.

Iwusizo kangakanani i-potassium permanganate yezitshalo?

Ngakho-ke, ukwelashwa kwe-potassium permanganate kwezitshalo:

1. Okokuqala, isixazululo esibuthakathaka se-potassium permanganate sisiza ukuvikela imbewu yezitshalo ezivela ezinambuzane eziqhamukayo kanye nezinhlamvu ze-fungal ezibusika. Yingakho ngaphambi kokutshala kwamukelwa ukuvimbela imbewu kanye nezilimo eziyizilimo eziyizigaxa zezitshalo isigamu sehora ngesisombululo esibuthakathaka se-potassium permanganate (ama-gramu angu-0.5 we-potassium permanganate ngamamitha ayizigidi eziyikhulu wamanzi).
2. Okwesibili, i-manganese ngokwayo imanyolo omuhle, ngenxa yokungena kwamanganese ne-potassium. Uma uchitha ingcosana ye-potassium permanganate ne-boric acid ebhakedeni lamanzi, uzothola ukugqoka okuphezulu kakhulu kwe-strawberries engadini, ama-currants, ama-blueberries, ama-raspberries nama-gooseberries. Kungcono ukufeza okunjalo ekuqaleni kwentwasahlobo. Basabela kahle ekugqokeni okuphezulu nge-potassium permanganate, cherry, iklabishi, i-peas, ubhontshisi, beet kanye namazambane.
3. Okwesithathu, isisombululo esibuthakathaka se-potassium permanganate sisetshenziswa ngokuphumelelayo njengendlela yokulungiselela ukwelashwa lapho ukwelapha izitshalo ezivela ezifweni ezihlukahlukene ezifisa emvelo. Isibonelo, ama-strawberries angasindiswa kusuka ekuboleni kwegrey, kanti utamatisi avela ku-phytophthora.

Ngesikhathi esifanayo, kufanele kukhunjulwe ukuthi i-permanganate ye-potassium ingokwalabo zinto okudingeka zisetshenziswe ngezinga elithile lokuqapha. Ukweqisa ngokweqile kwe-potassium permanganate engadini kungabangela izifo nokuwohloka kwezitshalo nokunciphisa ukuzala kwenhlabathi ngenxa yokugqithisa kwe-potassium kuyo. Sebenzisa i-potassium permanganate kungenzeka kuphela kulezo zindawo, inhlabathi ene-alkaline noma yokungathathi hlangothi.
