Cov muaj pes tsawg leeg yog txawv: chlorine fertilizer yog ib tug chiv nrog cov ntsiab lus chlorine siab. Feem ntau cov tshuaj chlorine muaj xws li potassium chloride, nrog cov ntsiab lus chlorine ntawm 48%. Sulfur-based compound chiv muaj cov ntsiab lus chlorine tsawg, tsawg dua 3% raws li lub teb chaws tus qauv, thiab muaj cov sulfur ntau.
Cov txheej txheem sib txawv: cov ntsiab lus chloride ion nyob rau hauv cov poov tshuaj sulfate compound fertilizer yog tsawg heev, thiab cov chloride ion raug tshem tawm thaum lub sij hawm tsim khoom; thaum cov tshuaj potassium chloride compound chiv tsis tshem tawm cov tshuaj chlorine uas tsim kev puas tsuaj rau cov qoob loo uas tsis muaj tshuaj chlorine thaum lub sij hawm tsim khoom, yog li cov khoom muaj ntau cov tshuaj chlorine.
Qhov ntau ntawm daim ntawv thov yog txawv: chlorine-based compound chiv muaj kev cuam tshuam tsis zoo rau cov qoob loo thiab zoo ntawm cov qoob loo uas tsis muaj tshuaj chlorine, txo cov txiaj ntsig zoo ntawm cov qoob loo kev lag luam; thaum sulfur-based compound chiv yog tsim rau ntau yam av thiab ntau yam qoob loo, thiab tuaj yeem txhim kho cov tsos thiab zoo ntawm ntau cov qoob loo kev lag luam tuaj yeem txhim kho qib ntawm cov khoom ua liaj ua teb.
Daim ntawv thov sib txawv: Cov tshuaj chlorine-based compound fertilizer tuaj yeem siv los ua cov chiv chiv thiab cov chiv ua chiv, tab sis tsis yog cov noob chiv. Thaum siv los ua chiv, nws yuav tsum tau siv ua ke nrog cov organic chiv thiab pob zeb phosphate hmoov ntawm nruab nrab thiab acidic av. Nws yuav tsum tau siv thaum ntxov thaum siv los ua topdressing fertilizer. Sulfur-based compound chiv tuaj yeem siv los ua cov chiv chiv, tshuaj pleev ib ce, cov noob chiv thiab cov hauv paus saum toj saud; sulfur-based compound fertilizer yog dav siv, thiab daim ntawv thov muaj txiaj ntsig zoo rau cov av tsis muaj sulfur thiab zaub uas xav tau cov sulfur ntau dua, xws li dos, leeks, qej, thiab lwm yam. Rapeseed, qab zib, txiv laum huab xeeb, taum pauv, thiab raum taum, uas. yog rhiab heev rau sulfur deficiency, teb zoo rau daim ntawv thov ntawm sulfur-raws li compound chiv, tab sis nws tsis haum rau siv rau hauv dej zaub.
Cov txiaj ntsig sib txawv: Cov tshuaj chlorine-based compound chiv tsim ntau cov tshuaj chloride ions nyob hauv cov av, uas tuaj yeem yooj yim ua rau muaj qhov tshwm sim tsis zoo xws li av compaction, salinization, thiab alkalization, yog li deteriorating cov av ib puag ncig thiab txo cov khoom noj muaj peev xwm ntawm cov qoob loo. . Cov tshuaj sulfur ntawm sulfur-based compound fertilizer yog thib plaub cov khoom noj loj tshaj plaws tom qab nitrogen, phosphorus, thiab potassium, uas tuaj yeem txhim kho lub xeev ntawm sulfur deficiency thiab ncaj qha muab sulfur zaub mov rau cov qoob loo.
Kev ceev faj rau cov tshuaj sulfur-based chiv: cov chiv yuav tsum tau siv rau hauv qab cov noob tsis muaj kev sib cuag ncaj qha kom tsis txhob hlawv cov noob; Yog hais tias lub compound fertilizer yog siv rau leguminous qoob loo, phosphorus fertilizer yuav tsum tau ntxiv.
Kev ceev faj rau cov tshuaj chlorine-raws li chiv: Vim muaj cov ntsiab lus chlorine siab, cov tshuaj chlorine-based compound chiv tsuas yog siv los ua cov chiv chiv thiab cov chiv chiv, thiab tsis tuaj yeem siv los ua cov noob chiv thiab cov hauv paus chiv keeb, txwv tsis pub nws yuav yooj yim ua rau cov hauv paus qoob loo thiab noob hlawv.
