Ferrous sulphate heptahydrate
Kuonekwa kweferrous sulphate ibhuruu-girini monoclinic kristaro, saka inowanzonzi "girini manyowa" mune zvekurima. Ferrous sulfate inonyanya kushandiswa mune zvekurima kugadzirisa iyo pH yevhu, kusimudzira kuumbwa kweklorophyll, uye kudzivirira chirwere cheyero chinokonzerwa nekushomeka kwesimbi mumaruva nemiti. Icho chinhu chakakosha kune asidhi-anoda maruva nemiti, kunyanya miti yesimbi. Ferrous sulfate ine 19-20% iron. Iyo yakanaka fotereza fetiraiza, yakakodzera michero ine acid-inoda, uye inogona kushandiswa kazhinji kudzivirira nekubata chirwere cheyero. Iron inodiwa pakuumbwa kweklorophyll muzvirimwa. Kana simbi yashomeka, kuumbwa kweklorophyll kwakavharwa, zvichikonzera zvirimwa kutambura neklorosis, uye mashizha anochinja kuita yero. Iyo yemvura inogadziriswa yeferrous sulphate inogona kupa zvakananga simbi inogona kutorwa uye kushandiswa nezvirimwa, uye inogona kudzikamisa kuenzana kwevhu. Iko kushandiswa kwesimbi sulphate, kazhinji kutaura, kana ivhu rekuchera rakanyatsodiridzwa ne 0.2% -0.5% mhinduro, pachave nemhedzisiro, asi nekuda kwesimbi yakanyungudika muvhu rakadirwa, inokurumidza kugadziriswa insoluble iron-iine komputa Inotadza. Naizvozvo, kuitira kudzivirira kurasikirwa kwezvinhu zvematare, 0.2-0.3% ferrous sulphate solution inogona kushandiswa kupfira zvirimwa pamashizha. -
Upfu Ammonium Sulphate
Ammonium sulphate mhando yakanaka kwazvo senitrogen fetiraiza, inokodzera zvirimwa zvakajairika, inogona kushandiswa seyakafanira fetiraiza, inogona kuita matavi uye mashizha kukura, kunatsiridza michero mhando uye goho, kusimudzira zvirimwa kuramba, zvakare kushandiswa kune iyo kugadzirwa kweyakaunganidzwa fetiraiza, BB fetiraiza.
