Ferrous sulphate heptahydrate
Cov tsos ntawm ferrous sulfate yog xiav-ntsuab monoclinic siv lead ua, yog li nws feem ntau hu ua "ntsuab chiv" hauv kev ua liaj ua teb. Ferrous sulfate tsuas yog siv hauv kev ua liaj ua teb txhawm rau txhawm rau kho qhov pH ntawm cov av, txhawb kev tsim cov chlorophyll, thiab tiv thaiv cov mob daj daj daj los ntawm hlau tsis tuaj yeem hauv paj thiab ntoo. Nws yog qhov tseem ceeb tsis tau rau cov kua qaub-hlub paj thiab ntoo, tshwj xeeb yog ntoo ntoo. Ferrous sulfate muaj 19-20% hlau. Nws yog cov zoo hlau chiv, haum rau cov kua txiv hlub cov nroj tsuag, thiab tuaj yeem siv ntau zaus los tiv thaiv thiab kho cov kab mob daj. Hlau yog qhov tsim nyog rau kev tsim cov chlorophyll hauv nroj tsuag. Thaum cov hlau tsis txaus, qhov tsim los ntawm chlorophyll yog thaiv, ua rau cov nroj tsuag raug mob los ntawm chlorosis, thiab cov nplooj tig daj ntseg daj. Kev daws aubous ntawm ferrous sulfate tuaj yeem muab cov hlau uas tuaj yeem nqus tau thiab siv tau los ntawm cov nroj tsuag, thiab tuaj yeem txo cov alkalinity hauv av. Daim ntawv thov ntawm ferrous sulfate, feem ntau hais lus, yog tias cov av potting ncaj qha nrog dej nrog 0.2% -0.5% kev daws teeb meem, yuav muaj qee yam tshwm sim, tab sis vim yog cov hlau yaj hauv cov av uas tau nchuav, nws yuav nrawm rau hauv ib qho insoluble hlau-muaj cov pajlaum Nws ua tsis tiav. Yog li, txhawm rau kom tsis txhob poob cov hlau, 0.2-0.3% cov tshuaj ferrous sulfate tuaj yeem siv los tua cov nroj tsuag ntawm cov nplooj.
