Yuav ua li cas yog poov tshuaj ntsev

Lub ntsiab yam tsim nyog rau txhua tus nroj tsuag yog poov tshuaj, nitrogen thiab phosphorus. Lawv ua cov tshuaj ntxiv rau qhov kev txhawb nqa ntawm cov av, tab sis txhua tus nyias tau siv los txhawb qhov tsis muaj peev xwm ntawm ib los sis lwm yam khoom.

Tsab ntawv no yuav qhia txog txhua yam txog potash ntsev - nws yog dab tsi, yog dab tsi potassium chiv, lawv qhov tseem ceeb rau cov nroj tsuag, yuav ua li cas potassium ntsev yog mined, yuav ua li cas nws yog siv nyob rau hauv liaj teb, dab tsi muab poov tshuaj rau cov nroj tsuag thiab cov cim qhia ntawm nws tsis muaj.

Yuav ua li cas yog poov tshuaj ntsev

Tshuaj ntsev cov ntsev - nws yog ib qho chaw thev av uas yog ib qho uas tsis yog xim hlau, yooj yim soluble ntsev nyob rau hauv daim ntawv chemogenic sedimentary pob zeb. Phosphorus ntsev yog ib qho khoom siv rau kev lag luam cov chemical rau cov kua qoob loo thiab yog sib xyaw ntawm sylvinite, kainit thiab potassium chloride.

Ntsev muaju yog tsim los ntawm evaporation thiab ces txias lub brine ntawm potash pas dej. Nyob rau hauv cov xwm, potash ntsev yog tso nrog lo ntsiab muag los yog txheej nyob ze qhov tshwm sim ntawm pob zeb ntsev.

Koj puas paub? Nyob rau hauv ib qho kev phooj ywg nyob rau hauv ancient Rome, txhua tus qhua tuaj yeem ntsev, thiab nyob rau hauv Is Nrias teb qhov kev qhia "Kuv noj nws ntsev" txhais hais tias "nws muaj kuv, thiab kuv tshuav nws".

Potash ntsev tsuas

Muaj ntau ntau cov potash ntsev deposit, thiab lawv muaj nyob rau hauv ntau lub teb chaws ntawm lub ntiaj teb. Qhov loj tshaj plaws ntawm potash ntsev yog nyob rau hauv Canada, Russia, Belarus, Lub teb chaws Yelemees, Teb chaws USA, Is Nrias teb, Ltalis, Israel, Jordan, Great Britain, Tuam Tshoj thiab Ukraine.

Qhov loj tshaj plaws ntawm potash ntsev nyob rau hauv Ukraine yog Stebnikovskoye thiab Kalush-Golinskoye deposits, nyob rau hauv Russia - lub Perm Krai (Berezniki), thiab nyob rau hauv Belarus - lub nroog ntawm Soligorsk.

Extraction ntawm potash ntsev, raws li tau zoo raws li pob zeb, yog ua los ntawm txoj kev tsuas. Qhov no yog qhov txaus ntshai, vim hais tias cov ntsev cov kab ntsev yog cov yam ntxwv ntawm lawv cov tsis muaj kev ntxhov siab thiab kev tsis sib haum xeeb, uas ua rau ntau lub cev nyob hauv cov pob zeb.

Cov khoom qab zib uas muab rho tawm yog hloov dua siab tshiab los ntawm cov khoom noj khoom haus ua rau cov kua qaub kua txiv looj ntsej muag, uas tsuas muaj ob hom - Cainites thiab sylvinites. Yog li tsis heev concentrated txheej ntawm ntsev yog tiav. Cov nplua nuj cov tsiaj txhu yog ua tiav hauv cov tshuaj nroj tsuag.

Koj puas paub? Muaj ntau haiv neeg tau ua raws li kev cai "ntsev" me nyuam yug los txhawm rau tiv thaiv lawv ntawm cov ntsuj plig phem uas muaj lub plhom, kab mob, thiab cov menyuam yaus.

Qhov twg yog potassium ntsev siv nyob hauv kev ua liaj / teb

Tshuaj ntsev cov ntsev yog siv dav hauv lub teb chaws kev lag luam: thiab nyob rau hauv cov tawv nqaij thiab xim, thiab hauv pyrotechnics, thiab hauv cov tshuaj ua lag luam, thiab hauv kev siv hluav taws xob, thiab hauv tshuaj, thiab hauv cov khob thiab xab npum, tab sis kev siv cov kua ntsev hauv kev ua liaj ua teb raws li ib qho kev siv chiv feem ntau. Cov tshuaj qej chlorides tsuas yog qhov tseem ceeb tshaj rau kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag.

Muaj ob peb ntau yam ntawm potash chiv raws li potash ntsev: poov tshuaj sulphate, poov tshuaj magnesia, poov tshuaj chloride, potash ntsev, ntsev potash, kainit.

Nyob rau hauv poov tshuaj chloride muaj 50-60% ntawm cov poov tshuaj thiab ib qho admixture of chlorine, ib qho tseem ceeb npaum li cas uas tsim kev puas tsuaj rau cov txiv hmab txiv ntoo ntoo. Yog li ntawd, nws yog ib qhov tsim nyog los cia nws nyob rau hauv cov qoob loo sensitive rau chlorine ua ntej (tshwj xeeb tshaj yog rau berries thiab strawberries) thiaj li chlorine yog ntxuav mus rau hauv tob txheej ntawm cov av.

Phosphorus sulphate - qhov zoo tshaj plaws ntawm potash chiv rau txiv hmab txiv ntoo thiab Berry cov qoob loo. Nws tsis muaj teeb meem impurities ntawm sodium, magnesium thiab chlorine.

Tshuaj ntsev cov ntsev sawv cev los ntawm ib tug sib tov ntawm poov tshuaj chloride nrog sylvinite, thiab nws yog pom zoo siv nws tsuas yog rau lub caij nplooj zeeg daim ntawv thov raws li lub ntsiab fertilizer rau kev khawb. Tus nqi ntawm daim ntawv thov mus rau cov av ntawm poov tshuaj ntsev yog 30-40 g ib square meter. 40% poov tshuaj ntsev yog contraindicated raws li ib tug fertilizer rau Berry cov qoob loo. Ntshav kua ntsev yog qhov tshwj xeeb tshaj yog thaum nws siv los hnav khaub ncaws saum taub hau.

Cov tshuaj nitrate nitrate siv rau pub cov nroj tsuag thaum lub sij hawm ripening ntawm lawv cov txiv hmab txiv ntoo thiab rau cog qoob loo.

Kalimagneziya tsim rau noj cov nroj tsuag uas muaj kev nkag mus rau chlorine thiab uas haus ntau ntawm magnesium nrog rau potassium (flax, clover, qos yaj ywm).

Ntoo tshauv Nws yog suav hais tias feem ntau cov nqis pob zeb hauv av fertilizer, uas muaj lub ntsiab macronutrients (phosphorus, poov tshuaj, magnesium, calcium). Tshauv tuaj rau lub sijhawm twg los tau ntawm lub xyoo. Tshauv yog heev tseem ceeb raws li ib tug to top hnav khaub ncaws rau paus cov qoob loo, qos yaj ywm, cabbage, currants thiab lwm cov qoob loo.

Tag nrho cov poov tshuaj chiv yog nkag soluble nyob rau hauv dej. Nws muaj ntau txoj kev uas yuav thov tau potash fertilizer rau cov av. Nyob rau hauv tag nrho cov txiv hmab txiv ntoo thiab Berry cov qoob loo nyob rau hauv qhib hauv av, nws yog ib qhov zoo tshaj plaws los coj lawv nyob rau hauv lub caij nplooj ntoos zeeg nyob rau hauv kev khawb raws li lub ntsiab fertilizer.

Kua mis chiv kuj tuaj yeem siv rau ntub qe nyob rau hauv thaum ntxov caij nplooj ntoos hlav. Hais txog thaum nws yog zoo dua ua potash chiv nyob rau hauv ib qho kev tiv thaiv hauv av, qhov no yuav ua tau thaum cog seedlings thiab paus dressings. Qhov zoo tshaj plaws tshwm sim yog tau thaum siv cov chiv nyob rau hauv lub caij nplooj ntoos zeeg.

Cov poov tshuaj chiv feem ntau yog siv ua ke nrog calcium chiv los sis txiv qaub, vim hais tias lawv tau cog nrog high acidity. Ib tug ntau ntawm poov tshuaj ua grapes tawm ntawm cov av, yog li ntawd nws yuav tsum tau fertilized nrog poov tshuaj-muaj chiv txhua xyoo.

Koj ua tsis tau chiv nrog chlorine rau txiv lws suav thiab qos yaj ywm, lawv impair lub saj thiab txo lub starchiness ntawm qos yaj ywm.

Nyhuv ntawm poov tshuaj on nroj tsuag

Poov tshuaj yog ib qho tseem ceeb ntawm cov khoom noj khoom haus cov khoom noj rau cov nroj tsuag. Properties ntawm poov tshuaj yog heev ntau:

  • Nws ua rau lub cev metabolic nyob rau hauv cov nroj tsuag lub cev thiab li ua rau lawv tsis kam mus ua drought. Yog hais tias poov tshuaj tsis txaus, ces cov nroj tsuag ntau ntau wilted.
  • Cov tshuaj yaj yeeb muaj feem xyuam rau cov khoom siv roj nitrogen thiab carbohydrate, hauv photosynthesis thiab muaj cov nyhuv rau cov uas muaj cov organic acids thiab oxidation processes. Yog hais tias cov nroj tsuag tsis muaj potassium, ces protein synthesis yog inhibited, thiab cov txheej txheem metabolic yog cuam tshuam raws li ib tug.
  • Tsub kom Frost tsis kam ntawm cov nroj tsuag thiab pab nyob rau hauv tsim ntawm kev tiv thaiv rau ntau cov kab mob.
  • Nws activates enzymes muab kev koom tes hauv cov metabolism ntawm carbohydrates, thiab contributes rau cov qos yaj ywm starchiness thiab qab zib cov ntsiab lus ntawm beets thiab lwm cov qoob loo cov qoob loo.
  • Nws muab kev ruaj ntseg thiab lub zog rau cov nroj tsuag vim muaj kev nthuav dav ntawm cov fibers. Vim hais tias ntawm tsis muaj poov tshuaj, qhov ua me nyuam plab hnyuv siab raum ntawm cov nroj tsuag yog inhibited, thiab raws li ib tug tshwm sim, lub buds ntawm inflorescences maj mam daim ntawv, lub grains tsis tsim, thiab germination txo.
  • Txhim kho cellular metabolism.
  • Pab hloov cov monosaccharides rau poly-thiab oligosaccharides.
  • Txhawb nqa nplua nuj paj txiv hmab txiv ntoo thiab tag nrho fruiting.
  • Nws txhawb rau sau nrog siab saj thiab nce preservation.
Koj puas paub? Thawj cov tshuaj potassium tau tshawb pom los ntawm cov kws tshuaj Askiv Davy thiab muab nws lub npe "potash", thiab lub npe "potassium" tau hais nyob hauv 1809 los ntawm L.V. Gilbert. Nyob rau hauv cov xwm, poov tshuaj tsuas yog muaj nyob hauv seawater lossis minerals.

Cov cim qhia ntawm cov potassium deficiency nyob rau hauv cov nroj tsuag

Cov cim qhia ntawm ib tug tsis muaj poov tshuaj hauv nroj tsuag yog:

  • Cov nplooj yog them nrog xeb xo nqaij.
  • Lub extinction ntawm tus sawv thiab cov tswv yim ntawm nplooj.
  • Cov duab ntawm lub qia yog curved, nws maj mam tsim thiab ua daj ntseg hauv xim.
  • Hauv paus system yog tsim tsis zoo, uas tom qab cuam tshuam lub tawm los. Cov txiv hmab txiv ntoo yuav tsum me me thiab xoob.
  • Cov nroj tsuag yuav raug rau ntau kab mob.

Nws tseem ceeb heev! Sib txawv nroj tsuag muaj ib tug sib txawv xav tau rau poov tshuaj. Sunflower, qos yaj ywm, beets, cabbage, buckwheat thiab txiv hmab txiv ntoo ntoo yuav tsum no lub ntsiab lus tshaj plaws.

Av qeeg nrog cov tshuaj tiv thaiv kab mob

Cov qauv thiab cov yam ntxwv ntawm cov av sib txawv ntawm cov ntsiab lus ntawm potassium nyob rau hauv nws. Nws yog qhov zoo tshaj plaws kom poov hlau hnyav xau (av nplaum, loam), nyob rau hauv uas cov ntsiab lus ntawm lub tseem ceeb caij yog 3%. Nyob rau hauv lub teeb xau (xuab zeb thiab zeb) nws tsawg dua, tsis pub ntau tshaj 0.05%. Tsis tas yuav tsum tau pub noj no tsuas yog ntsev cov kua roj thiab cov av dub xwb.

Nws tseem ceeb heev! Peaty xau yog cov pluag tshaj nyob rau hauv cov nqe lus ntawm cov poov tshuaj ntsiab lus.
Qhov siab tshaj plaws ntawm potassium yog nyob rau hauv av sab ntug, tab sis ib tug loj npaum li cas ntawm lub keeb tsis tau absorbed los ntawm cov nroj tsuag, vim hais tias nws yog ib feem ntawm cov tsis zoo soluble tshuaj. Thiab tsuas yog 10% ntawm cov potassium yog muaj rau absorption.

Tias yog vim li cas, thiaj li nce lub tawm los, lub deficiency ntawm muab kev pab cuam yuav tsum tau sau nrog potash chiv. Lawv dissolve zoo nyob rau hauv dej, thiab poov tshuaj ua tau npaj muaj rau cov qoob loo cog.

Potash chiv - ib qho ntawm cov pob zeb hauv av thawj chiv siv hauv kev ua liaj / teb. Daim ntawv teev cov khaub ncaws saum toj kawg nkaus yuav tso cai rau koj kom tau ib lub siab dav thiab tiv thaiv koj tus kheej los ntawm ntau cov kab thiab kab mob.
