Qab Zib Sulphate
Cov poov tshuaj sulfate yog cov inorganic ntsev nrog rau tus qauv tshuaj K Ψ so Ψ. Feem ntau, cov ntsiab lus ntawm K yog 50% - 52%, thiab cov ntsiab lus ntawm S yog li 18%. Cov ntshiab sodium sulfate yog cov tsis muaj xim siv lead ua, thiab cov tsos ntawm kev ua liaj ua teb potassium sulfate feem ntau yog lub teeb daj. Cov poov tshuaj sulfate yog cov dej-soluble poov tshuaj zoo vim tias nws tsawg hygroscopicity, tsis noj, muaj lub cev zoo thiab daim ntawv thov yooj yim. Cov poov tshuaj sulphate tshwj xeeb tshaj yog rau cov kev lag luam cog qoob loo, xws li haus luam yeeb, txiv quav ntswv nyoos, kab qab zib beet, tshuaj yej cog, qos, flax thiab ntau yam txiv ntoo. Nws tseem yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj chlorine dawb nitrogen, phosphorus, potassium ternary compound fertilizer. Cov poov tshuaj sulfate yog tshuaj lom neeg hauv nruab nrog cev, muaj lub cev ua kua qaub, uas tsim nyog rau ntau hom av (tsis suav cov av uas dej nyab) thiab cov qoob loo. Tom qab ua ntawv thov rau cov av, cov poov tshuaj ion tuaj yeem nqus ncaj qha los ntawm cov qoob loo lossis nqus tau los ntawm cov av colloids. Cov txiaj ntsig tau pom tias poov tshuaj sulfate tuaj yeem siv rau Cruciferae cov qoob loo thiab lwm cov qoob loo uas xav tau ntau leej faj hauv av nrog cov leej faj.
