Potassium chloride thiab potassium sulfate yog ob qho tib si potash chiv, dab tsi yog qhov txawv? Qhov twg zoo dua?
Potassium yog ib qho ntawm peb lub ntsiab tseem ceeb uas cov nroj tsuag xav tau, thiab lub luag haujlwm ntawm potassium chiv tseem ceeb heev, tshwj xeeb tshaj yog cov qoob loo xws li qos yaj ywm qab zib, radishes, thiab qos yaj ywm, uas yog inseparable ntawm poov tshuaj. Ntawm paj rwb, poov tshuaj chiv feem ntau yog poov tshuaj chloride, poov tshuaj sulfate thiab poov tshuaj dihydrogen phosphate, tab sis poov tshuaj dihydrogen phosphate feem ntau yog siv los ua phosphorus-potassium compound fertilizer, uas feem ntau yog siv rau foliar txau.
Kab lus no feem ntau yog tham txog potassium chloride thiab poov tshuaj sulfate, ob qho tib si ntawm cov poov tshuaj chiv. Qhov txawv ntawm lawv yog dab tsi?
1. Qhov sib txawv ntawm potassium chloride thiab potassium sulfate
（1）Zoo sib xws ntawm ob lub potash chiv
Ob qho poov tshuaj chloride thiab potassium sulfate tuaj yeem yaj hauv dej thiab tuaj yeem nqus ncaj qha thiab siv los ntawm cov qoob loo. Nyob rau tib lub sij hawm, lawv yog tag nrho cov physiologically acidic chiv, yog li ntawd lawv yuav tsum tsis txhob siv ib leeg ntev, tshwj xeeb tshaj yog nyob rau hauv acidic av, txwv tsis pub nws yuav ua rau av acidification thiab hardening. Yog li ntawd, nws yog qhov zoo tshaj plaws los siv nws nrog alkaline chiv (calcium magnesium phosphate fertilizer, txiv qaub). Tsis tas li ntawd, lawv yog tag nrho cov chiv tsis muaj organic, thiab cov poov tshuaj ions sib cais tom qab daim ntawv thov tuaj yeem nqus tau los ntawm cov av organic teeb meem, tab sis hauv cov av tsis muaj cov organic teeb meem, xws li cov av xuab zeb, cov poov tshuaj ions tau yooj yim poob nrog dej, yog li lawv yuav tsum tau siv rau hauv cov av. ua ke nrog cov organic chiv, thiab Siv ib qho tsim nyog ntawm cov txiv qaub kom tsis txhob cuam tshuam cov qauv thiab cov khoom ntawm cov av.
（2）Qhov sib txawv ntawm ob lub potash chiv
Potassium Chloride: Cov tsos yog dawb los yog lub teeb daj muaju, qee zaum muaj cov ntsev hlau uas liab. Nws yog yooj yim soluble nyob rau hauv dej thiab yog ib tug high-concentration ceev-acting poov tshuaj chiv. Nws yog hygroscopic thiab yooj yim agglomerated los ntawm noo noo, tab sis agglomeration tsis cuam tshuam rau kev siv cov nyhuv. Potassium chloride muaj cov poov tshuaj oxide siab, feem ntau 50 feem pua -60 feem pua, tuaj yeem yaj hauv dej, thiab muaj txiaj ntsig sai tom qab thov.
Potassium sulfate: dawb los yog dawb dawb crystals, poov tshuaj cov ntsiab lus ntawm txog 50 feem pua, sulfur ntsiab lus ntawm txog 18 feem pua, yooj yim soluble nyob rau hauv dej, tsis muaj hygroscopicity, tsis yooj yim rau agglomerate, yooj yim mus thov, yog ib tug zoo dej-soluble ceev-acting. poov tshuaj chiv.
Tus nqi ntawm cov poov tshuaj sulfate yog me ntsis siab dua li ntawm cov poov tshuaj chloride, tab sis los ntawm kev xav ntawm cov ntsiab lus ntawm cov khoom noj khoom haus, cov ntsiab lus ntawm cov poov tshuaj chloride yog li 10 feem pua siab dua li ntawm cov poov tshuaj sulfate. Nyob rau tib lub sijhawm, qhov solubility ntawm potassium chloride yog siab dua li ntawm cov poov tshuaj sulfate. Ua piv txwv li 10 degree, 100 grams dej tuaj yeem yaj 31 grams ntawm potassium chloride, thaum poov tshuaj sulfate tsuas yog yaj 10 grams. Nyob rau tib lub sijhawm, potassium chloride yog qhov nrawm dua li cov poov tshuaj sulfate, tsuas yog 11.2 feeb, qhov solubility ntawm chloride tuaj yeem ncav cuag 90 feem pua, thiab lub sijhawm tsuas yog 1/3 ntawm potassium sulfate.
Yog li ntawd, kuj muaj qhov tsis zoo hauv kev siv cov poov tshuaj sulfate. Thaum daim ntawv thov cheeb tsam loj, cov tshuaj chiv siv kuj loj, thiab tus nqi dissolution qeeb. Tshwj xeeb tshaj yog nyob rau hauv Xinjiang, cov dej tsis zoo yog nyuaj. Kev siv cov poov tshuaj sulfate hauv paj paj yuav ua rau calcium sulfate los nag thiab thaiv cov dripper. .
2. qhov txawv ntawm qhov kev thov
（1）Siv cov qoob loo
Potassium chloride muaj chloride ions, thiab nws daim ntawv thov hauv ramie thiab paj rwb teb tuaj yeem txhim kho cov txiaj ntsig thiab fiber ntau zoo; Txawm li cas los xij, thaum siv rau cov qoob loo uas tsis muaj tshuaj chlorine tshwj xeeb rau cov tshuaj chlorine, xws li tshuaj yej tsob ntoo, haus luam yeeb, thiab qhiav, cov tshuaj tsw qab yuav raug txo kom tsawg, thiab cov tshuaj tsw qab ntawm cov luam yeeb yuav raug txo. Kev puas tsuaj; chloride ions yuav txo tau cov qoob loo thiab qhov zoo ntawm cov tshuaj chlorine-tsis txhob muaj cov qoob loo xws li beets, qos yaj ywm, qos yaj ywm qab zib, thiab txiv hmab txiv ntoo. Yog tias cov qoob loo no yuav tsum siv cov tshuaj poov tshuaj chloride, nws yog qhov zoo tshaj plaws los compost lawv nrog cov organic chiv ua chiv, los yog siv lawv thaum ntxov li sai tau. Potassium sulfate tsis muaj chlorine, thiab nws daim ntawv thov ntau yog dav dua li ntawm potassium chloride. Nws yog siv rau tag nrho cov qoob loo uas tsis muaj tshuaj chlorine xws li haus luam yeeb, qos yaj ywm qab zib, qab zib, thiab cov qoob loo cruciferous sulfur-hlub, thiab cov nyhuv zoo dua li cov poov tshuaj chloride.
（2）Siv cov av
Potassium sulfate yuav tsum tsis txhob siv rau thaj av uas tsis decomposed, txhawm rau tiv thaiv kev txo cov sulfide rau hydrogen sulfide thiab tshuaj lom rau hauv paus system ntawm cov qoob loo. Yog li ntawd, hom phiaj no yog tsim nyog rau daim ntawv thov ntawm poov tshuaj chloride, thiab cov tshuaj chloride ions nyob rau hauv cov poov tshuaj chloride yog leached mus rau hauv qab cov av txheej, uas yuav zam tau nws cov kev tsis zoo rau cov qoob loo. Tsis tas li ntawd, chloride ions muaj qhov tshwj xeeb inhibitory cuam tshuam rau cov kab mob nitrifying hauv av, uas tuaj yeem txo qhov poob ntawm denitrification los ntawm nitrification thiab denitrification ntawm ammonium nitrogen chiv. Txawm li cas los xij, rau cov av uas hnyav dua salinity thiab alkali, nws tsis tsim nyog siv cov tshuaj poov tshuaj chloride ntev, txwv tsis pub nws yuav ua rau salinity thiab alkali hnyav dua.
（3）Txoj kev thov
Ntxiv nrog rau kev siv cov chiv chiv thiab hnav khaub ncaws saum toj kawg nkaus, potassium sulfate kuj tseem siv tau los ua cov noob chiv thiab hnav khaub ncaws sab saum toj sab nraud. Tus nqi ntawm lub hauv paus chiv feem ntau yog {{{0}}} kg ib mu, tus nqi ntawm kev hnav khaub ncaws saum toj kawg nkaus yog 6-8 kg ib mu, tus nqi ntawm cov noob chiv feem ntau yog 2-3 kg ib mu, thiab qhov concentration ntawm foliar tshuaj chiv yog 0.5 feem pua -2 feem pua; thiab potassium chloride tsuas yog siv tau. Nws yog siv los ua lub hauv paus chiv thiab hnav khaub ncaws saum toj kawg nkaus, thiab tsis tuaj yeem siv los ua cov noob chiv thiab hnav khaub ncaws saum toj kawg nkaus sab nraum cov hauv paus hniav, vim chloride ions muaj kev kub nyhiab ntawm cov noob germination thiab cov tub ntxhais hluas stems thiab nplooj. Tus nqi ntawm lub hauv paus chiv feem ntau yog 15-20 kg ib mu, thiab tus nqi ntawm kev hnav khaub ncaws saum toj kawg nkaus yog 8-10 kg ib mu.
Nyob rau hauv luv luv, chiv yog tus yuam sij rau siab yield thiab zoo sau. Txawm hais tias nws yog cog los ntawm koj tus kheej lossis qhia lwm tus cog, koj yuav tsum siv txoj hauv kev kom yog fertilizing thiab fertilizing.
