    Urea

    Lemandou urea nrog 46 feem pua ​​nitrogen cov ntsiab lus, yog qhov khoom lag luam nitrogen chiv zoo. Urea chiv siv dav hauv kev ua liaj ua teb. Nws yog daim ntawv tshaj plaws ntawm nitrogen fertilizer siv thoob ntiaj teb. Lawv suav tias yog qhov khoom lag luam nitrogen. Ua los ntawm ammonia thiab carbon dioxide, nws muaj cov ntsiab lus siab tshaj plaws ntawm ib qho ntawm cov khoom ntim nitrogen. Ua cov khoom lag luam, urea tuaj yeem siv ncaj qha rau cov av uas siv cov khoom siv sib kis tau yooj yim. Ntxiv nrog rau av thov, urea chiv kuj tseem siv tau hauv fertigation lossis ua daim ntawv thov foliar. Txawm li cas los xij, kev siv tshuaj urea yuav tsum tsis txhob siv cov av kab lis kev cai tsawg dua, vim tias urea yuav tso tawm tam sim ntawd tawm ntawm cov thawv.

  • Ammonium Sulphate

    Ammonium Sulphate

    Ib qho zoo nitrogen chiv (feem ntau hu ua chiv teb hmoov) yog qhov tsim nyog rau cov av thiab qoob loo. Nws tuaj yeem ua rau cov ceg thiab nplooj loj hlob zoo, txhim kho cov txiv hmab txiv ntoo zoo thiab muaj txiaj ntsig, thiab txhim kho cov qoob loo tsis kam rau kev puas tsuaj. Nws tuaj yeem raug siv los ua cov hauv paus chiv, topdressing chiv thiab noob chiv.

  • Magnesium Sulphate

    Magnesium Sulphate

    MagnesiumSulphate tuaj yeem muab cov khoom noj muaj txiaj ntsig zoo rau cov qoob loo uas nws ua rau cov qoob loo loj hlob thiab nce cov qoob loo, nws kuj pab xoob cov av thiab txhim kho av zoo.

  • Potassium Sulphate

    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.

  • Zinc Sulphate

    Zinc Sulphate

    Nws tuaj yeem siv los tiv thaiv cov kab mob ntawm cov txiv hmab txiv ntoo ntoo ntawm cov txiv ntoo, thiab nws tseem yog ib hom muaj tshuaj los siv ntxiv rau cov qoob loo zinc kab kawm chiv. Nws tuaj yeem raug siv los ua cov hauv paus chiv, quav chiv, thiab lwm yam. [6] Zinc yog ib qho tseem ceeb ntxiv rau cov nroj tsuag. Cov paj ntoo dawb yog yooj yim tshwm sim hauv pobkws vim zinc tsis txaus. Thaum lub zinc tsis txaus, lub yub yuav nres loj hlob lossis tuag. Tshwj xeeb rau qee qhov av xuab zeb loam av lossis thaj teb muaj pH tus nqi siab, zinc chiv xws li zinc sulfate yuav tsum tau siv. Qhov nce ntawm zinc chiv kuj muaj cov txiaj ntsig ntawm kev nce siab. Kev siv cov noob: siv 0.04 ~ 0.06 kg zinc chiv, dej 1 kg, noob hnav khaub ncaws 10 kg, teeb rau 2 ~ 3 teev tseb. Ua ntej sowing, zinc fertilizer tau thov rau rhizosphere txheej nrog 0.75-1kg / mu. Yog tias cov xim nplooj xim yog lub teeb nyob rau ntawm cov yub theem, zinc chiv tuaj yeem muab txau nrog 0.1kg / mu
