Cov kua tshuaj chiv zoo li cas yog tsim los ntawm kev lag luam niaj hnub? Qhov no yog feem ntau poov tshuaj-magnesium (poov tshuaj oxide - txog li 25-26%, magnesium - txog 11-18%, tsis muaj tshuaj) Kalimag (poov tshuaj hydroxide txog 24%, kuj muaj tsis muaj tshuaj nyob rau hauv nws muaj pes tsawg leeg), poov tshuaj ntsev (ua ke Formula ntawm sylvinite thiab potassium chloride, potassium oxide - ntau tshaj 40%, cov ntsiab lus ntawm cov tshuaj chlorine).

Potash fertilizer rau txiv lws suav uas hais feem ntau poov tshuaj tshuaj dawb thiab poov tshuaj sulfate. Thawj ntawm cov no yog ib qho dawb crystalline hmoov, soluble hauv dej. Poov tshuaj chloride yog ua los ntawm sylvinite los ntawm qhov kev tshem tawm ntawm impurities, uas ua rau ib tug concentrate nrog ib tug high school cov kev faib ua feem ntawm cov mineral tshuaj (mus txog 62% ntawm cov poov tshuaj oxide). Lub txiaj ntsim ua rau tsis zoo absorbs noo, yog li nws tsis ncuav mog qab zib, yuav khaws cia rau hauv ntim yas thiab yooj yim tauj mus rau thaj av.

Potash rau txiv lws suav nyob rau hauv daim ntawv ntawm cov poov tshuaj tshuaj dawb yog ua lub caij nplooj zeeg mus tshaj tshuaj "tshuav" nyob rau hauv qis khaubncaws sab nraud povtseg ntawm cov av thiab twb tsis muaj rau cov nroj tsuag keeb kwm. Tab sis lwm yam khoom - potassium sulfate - lacks xws li ib tug tsis muaj cov ntsiab lus chlorine nyob rau hauv cov tshuaj lom neeg muaj pes tsawg leeg, uas tso cai rau nws mus rau feem ntau siv fertilizer ntawm no chav kawm nyob rau tam sim no lub sij hawm.

Qee ntawm poov tshuaj sulfate yog siv raws li lub ntsiab los yog caij nplooj ntoos hlav-lub caij ntuj sov potash rau txiv lws suav. Lawv tshuaj nyob tus yeees (txog peb feem pua ntawm magnesium, 18% cov leej faj, thiab hais txog 50% poov tshuaj oxide) los mus tiv thaiv wilting ntawm nplooj thiab tau ib tug zoo sau. Tus nqi ntawm chiv yog xaiv ib lub zuj zus nyob rau hauv txhua rooj plaub, nyob ntawm seb lub climatic tej yam kev mob, av acidity, theem ntawm cov qoob loo tig, cog ntau ntau yam thiab lwm yam chiv. Piv txwv li, qhov qhia txog ntawm manure (nitrogen pawg) txo cov txiaj ntsim ntawm assimilation ntawm poov tshuaj chiv.

Tom qab ntawd, koj yuav tsum txiav txim siab seb cov khoom siv ntshiab npaum li cas koj xav tau qib no (hais tias 20 gram potassium per square meter) thiab xam qhov uas yuav tsum tau siv cov chiv. Nyob rau hauv peb cov ntaub ntawv, uas cov nroj tsuag tau txais 20 g. Poov tshuaj, koj yuav tsum noj, piv txwv li, 40 grams potassium sulphate, vim hais tias nws tsuas ib nrab muaj oxide ntawm lub caij peb xav tau. Ib qho zauv yooj yim, tab sis tsis muaj txoj kev txiav txim siab txog kev cai yog ua raws li cov lus pom zoo ntawm lub ntim ntawm ib hom kev chiv.
