Cov tshuaj ua liaj ua teb ib txwm muaj xws li urea, superphosphate, thiab compound chiv. Nyob rau hauv niaj hnub kev ua liaj ua teb ntau lawm, dej-soluble chiv sawv tawm los ntawm cov tsoos chiv thiab ceev ceev nyob rau hauv ib qho chaw nyob rau hauv lub lag luam chiv los ntawm kev tsim txiaj ntawm qhov zoo ntawm ntau yam khoom noj khoom haus thiab kev nqus siab thiab kev hloov pauv siab. Yog li, dab tsi yog qhov zoo ntawm cov dej soluble fertilizer? Nws tus nqi piv nrog cov tshuaj chiv li cas?
Nws cov nyhuv dej-soluble tuaj yeem yaj thaum nws ntsib dej, thiab yuav tsis muaj cov khoom seem. Nws tuaj yeem yaj tag nrho hauv dej. Los ntawm kev siv dej, tshuaj tsuag, thiab lwm yam, nws ncaj qha ua rau hauv paus system thiab nplooj nplooj ntawm cov qoob loo kom ua tiav lub hom phiaj ntawm kev siv hluav taws xob siab. Txawm li cas los xij, muaj cov tsis muaj dej-soluble impurities hauv cov tshuaj chiv, uas yuav tsum tau yaj thiab lim ua ntej irrigation thiab fertilization. Kev nqus ntawm cov as-ham los ntawm cov qoob loo tseem yuav cuam tshuam los ntawm impurities. Thaum siv cov tshuaj chiv, nws yog ib qho tsim nyog yuav tau muab cov chiv chiv rau ntawm cov qoob loo ua ntej, thiab tom qab ntawd irrigate. Cov txheej txheem fertilization yog qhov nyuaj thiab cov qoob loo nqus cov nyhuv tsis zoo. Piv nrog rau cov dej-soluble chiv siv tam sim no, nws muaj teeb meem ntau dua. Niaj hnub nimno dej-soluble chiv muaj ntau yam formulations. Los ntawm kev siv txoj siv dej siv chiv thiab dej-fertilizer kev koom ua ke, feem ntau ntawm cov nplua nuj cov as-ham tuaj yeem nqus tau los ntawm cov qoob loo, thiab qhov kev nqus hloov pauv ntau dua ob npaug ntawm cov chiv zoo tib yam, siab txog 80% -90%.
Piv nrog cov tshuaj chiv, dej-soluble chiv muaj ntau nplua nuj nyob rau hauv cov as-ham. Nws tsis tsuas yog muaj nitrogen, phosphorus, thiab poov tshuaj xav tau rau kev loj hlob qoob loo, tab sis kuj yog nplua nuj nyob rau hauv nruab nrab thiab kab kawm, tshwj xeeb tshaj yog ntxiv "nplua nuj micro-carbon", uas yog siv rau cov qoob loo ua lub luag haujlwm tseem ceeb hauv kev muab cov pa roj carbon me me. cov ntsiab lus los daws qhov teeb meem ntawm qoob loo cov pa roj carbon monoxide.
