Sera yog plaub uas tseem ceeb tshaj plaws hauv hom qoob loo tom qab nitrogen, phosphorus, phosphorus thiab potassium. Yav dhau los, cov nroj tsuag tau dawb xa cov sulphur ntawm cov ntug dej nag, tab sis raws li cov dej phwj tuaj ua kom cov txiv ntoo poob nrog cov nag, txo qis. Thiab agrariandians yuav tsum tau nkhaus tawm rau cov chiv nrog grey, txij li tsis muaj cov qoob loo tuaj yeem txo qis, qhia cov ntawv sau rau hauv nws tsab xov xwm ntawm portal www.aagricator.com.
Sulphur tsis txaus hauv cov nroj tsuag nplej zoo li no.
"Raws li txoj cai, nplej nrog cov ntses sulfur yog daj thiab qis dua thiab tau hais txog cov kws muaj txuj ci ua ntej, - Qhov twg cov av fertility tus kws tshaj lij los ntawm cov tsev kawm ntawv ntawm Kansas. - Koj tuaj yeem pom thaj chaw muaj qhov tsis txaus ntawm cov txiv leej txiv ntawm cov roob lossis nqes hav uas yaig tshwm sim thiab cov ntsiab lus ntawm cov organic tshuaj poob qis. Los yog hom nplej nyob rau hauv thaj chaw uas txheej txheej sab saud tau raug tshem tawm lossis txiav tawm yog ua - ua kom haum rau cov tsos mob kuj tseem muaj cov tsos mob. "
"Nco tseg: Qhov tsis muaj peev xwm ntawm cov qoob loo loj hlob feem ntau yuam kev rau tsis muaj nitrogen (n). Txawm li cas los xij, tsis zoo li nitrogen deficiency, thaum cov nplooj qub yog "hlawv" thiab daj, daj ntseg feem ntau tshwm sim ua ntej ntawm cov tub ntxhais hluas lossis sab saum toj ntawm nplooj ntoo. Cov nroj tsuag nplej nrog qhov tsis muaj peev xwm ntawm S thaum kawg ua chlorobic, "piav qhia Ruiz Diaz.
Cov tub rog Sulphur tsis txaus hauv cov qoob mog yog tshwm sim thaum ntxov, ua ntej cov kab mob organic ntawm cov av, thiab ua ntej cov kab mob organic ntawm cov av, thiab ua ntej cov kab mob organic ntawm cov av thiab cov orginic los ntawm cov khoom sib xyaw ua ke rau kev siv cov khoom siv salas s (sulfate).
"Qhov tsis muaj leej faj sulfur feem ntau nyuaj rau kev txheeb xyuas, vim tias Chlorosis tsis pom tseeb," Ruiz Daiz ceeb toom. - Cov kab lis kev cai nrog cov kab mob Sulphur tsis tuaj yeem ua tau qis, nyias-nplai thiab ntxaiv-puab. Hais txog cov nplej thiab lwm cov qoob loo cov qoob loo, kom loj hlob tau qeeb. Lub caij ntuj no kev sib tw Txhua xyoo ntawm cov txhauv no tseem muaj zog vim tias qeeb qeeb zuj zus thiab tsis muaj qhov zoo heev. "
Yog tias nyob rau hauv keeb kwm ntawm teb twb tau teeb tsa cov Sulfur tsis txaus siab, cov neeg ua liaj ua teb yuav xav txog kev siv S raws li kev tiv thaiv nyob rau lub caij ntuj no.
Cov khoom dab tsi nrog grey yuav siv tau
Muaj ntau ntau s-fertilizers uas zoo haum rau cov caij nyoog ua thiab tshem tawm cov sulfur tsis txaus ntseeg:
Ammonium sulfate yog cov khoom siv qhuav uas yog ib qho chaw ntawm ob qho tib si nitrogen thiab S. Txawm li cas los xij, nws muaj lub peev xwm siab tsim muaj peev xwm, thiab cov ntawv ntev. Ammonium sulfate hais txog cov kev xaiv zoo rau kev ua ntej sowing lossis pub mis kom kho cov kab mob uas twb muaj lawm.
Gypsum yog calcium sulfate thiab feem ntau muaj nyob rau hauv ib daim ntawv hydrated muaj 18.6% s, thiab hauv granules, uas tso cai rau koj sib xyaw nrog lwm cov ntaub ntawv. Txij li qhov no yog qhov chaw sulfate, nws yuav nkag tau tam sim ntawd thiab haum rau lub caij nplooj hlav pub mis. Txawm li cas los xij, tus gypsum tsis yog li soluble hauv dej raws li ntau chiv, suav nrog ammonium sulfate.
New cov khoom lag luam, xws li microessentions thiab lwm tus, yog cov khoom siv los ntawm ammonium phosphate, uas suav nrog S, thiab qee kis tau xws li zinc. Nyob rau hauv feem ntau ntawm cov khoom lag luam no, s yog tam sim no nyob rau hauv daim ntawv ntawm kev sib xyaw ntawm Elementary s thiab sulfate.
Ammonium thiosulfate yog cov nrov tshaj plaws s-muaj cov khoom siv nyob rau hauv kev tsim cov chiv ua kua chiv, vim nws tau tshaj cov kev daws teeb meem nitrogen thiab lwm cov khoom tiav ua tiav. Haum rau lub caij nplooj ntoos hlav pub mis.
Poov tshuaj thiosulfate yog cov khoom ua kua ua kua, nws tuaj yeem sib xyaw nrog lwm cov kua chiv. Zoo li thiosulfate, haum rau kev pub mis thaum ntxov nyob rau lub caij nplooj ntoo hlav.
Raws li plaub qhov tseem ceeb tshaj plaws uas tseem ceeb tshaj plaws yog lub luag haujlwm tseem ceeb hauv kev tsim cov amino acids, protein thiab cov roj thiab yog qhov tseem ceeb rau kev tsim cov chlorophyll.
Nitrogen thiab Sulphur muaj feem cuam tshuam rau qee yam, vim tias tus neeg sawv cev ua si lub luag haujlwm ntawm kev ua kom zoo nkauj ntawm nitratredundase enzyme, uas pab hloov cov amino acids. Yog li ntawd, kev ua tau zoo ntawm nitrogen siv yuav txo nrog ib tug tsis muaj leej faj, hais ruis diaz.
