Yuav siv li cas poov tshuaj sulfate compound chiv:

(1) Nws tuaj yeem siv los ua chiv. Thaum twgpoov tshuaj sulfate yog siv los ua chiv hauv cov av qhuav, cov av yuav tsum tau ua kom tob tob txhawm rau txhawm rau txhim kho cov poov tshuaj potassium thiab pab txhawb kev nqus ntawm cov hauv paus qoob loo thiab nce kev siv.

(2) Siv ua khaub ncaws saum toj kawg nkaus. Txij li cov poov tshuaj muaj qhov ua tau me me hauv cov av, nws yuav tsum tau siv rau hauv cov kab sib txuas ua ke lossis qhov rau hauv cov av txheej nrog ntom ntom los txhawb kev nqus dej.

(3) Nws tuaj yeem siv los ua noob chiv thiab ntxiv rau hauv paus topdressing. Tus nqi ntawm cov noob chiv yog 1.5-2.5 kg rau ib mu, thiab nws kuj tseem tuaj yeem ua rau hauv 2% -3% kev daws teeb meem ntxiv rau hauv paus. Rau

Cov poov tshuaj sulfateyog ib hom tshuaj dawb uas tsis muaj tshuaj chlorine, muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo potassium, tshwj xeeb tshaj yog hauv kev cog qoob loo uas muaj cov tshuaj chlorine xws li haus luam yeeb, du txiv hmab, txiv hmab txiv ntoo qab zib, tshuaj yej ntoo, qos yaj ywm, paj noob hlis thiab ntau yam ntoo txiv ntoo. Nws yog qhov tsis tseem ceeb Cov chiv tseem ceeb; nws tseem yog cov khoom siv tseem ceeb ntawm cov nitrogen zoo, phosphorus thiab potassium ternary compound chiv.
Cov poov tshuaj sulfatehom tshuaj chiv yog tsim los ntawm kev hloov pauv kub tsawg ntawm cov tshuaj potassium chloride, tshuaj sib xyaw ua ke, thiab tshuaj tsuag txheej txheem. Nws muaj kev ruaj ntseg zoo. Ntxiv rau peb lub ntsiab lus tseem ceeb tsim nyog rau cov nroj tsuag, N, P thiab K, nws tseem muaj S thiab Ca, Mg, Zn, Fe, Cu thiab lwm yam kab kawm. Hom chiv no haum rau ntau yam qoob loo ntsuab, tshwj xeeb yog cov tshuaj nkag rau tshuaj chlorine.
