Dab tsi ua rau kev siv ntawm superphosphate thiab hais tias nws yog ib tug fertilizer

Muaj ib zaug, nyob rau hauv 1669 xyoo, ib tug alchemist H.Brandt ua raws li nram no xyaum ua tej yam: zis nws twb evaporated rau dryness, lub resulting precipitate tau tov nrog xuab zeb thiab hluav ncaig, thiab ces tus sib tov twb rhuab nyob rau hauv ib tug kaw retort. Raws li ib tug tshwm sim, nws tau txais ib yam khoom uas muaj tej yam yees siv thaj chaw ntawm lub teeb nyob rau hauv qhov tsaus ntuj. Li ntawd, kuv twb xub tau phosphorus. Txij thaum ntawd los, nws coj ntau tshaj li peb puas xyoo tam sim no, qhov no tshuaj caij yog dav siv nyob rau hauv ntau yam teb kev lag luam thiab ua liaj ua teb. Wb tham txog dab tsi yuav muab rau lawv lub caij ntuj sov tsev siv ntawm superphosphate thiab qhov sib txawv ntau yam ntawm nws. Hopefully no tsab xov xwm yuav tsum xwm heev rau tag nrho cov neeg uas koom nyob rau hauv cov sau qoob rau ntawm cov qoob loo nyob rau hauv koj lub vaj.

Fertilizer nrog lub prefix "super"

Lub chaw ntawm no yam khoom uas yog kev cob cog rua nrog lub fact tias nws muaj, firstly, ib tug uas tsis yog-tshuaj lom, resistant rau hluav taws thiab tawg, thiab tib ob yog haum rau yuav luag txhua hom ntawm cov av. Daim ntawv thov ntawm superphosphate ua heev high loo ntawm maize, beet, qos yaj ywm, flax, zaub, cereals thiab lwm cov qoob loo. Ntxiv mus, kws txawj pom zoo kom zoo tau muab cov kev siv ntawm no substance nyob rau hauv nyob tus yeees ntawm lub ntsiab pub nrog ib tug me me npaum li cas mus rau hauv lub qhov dej ntawm kab los yog ncaj qha ua ntej lub sowing. Tej zaum koj twb sawv los ntawm lub sij hawm no rau lo lus nug ntawm yuav ua li cas npaum li cas koj yuav tsum tau ua kom qhov no chiv. Nco ntsoov tias kev siv ntawm superphosphate nyob nyob rau theem ntawm fertility ntawm cov av, thiab kev siv ntawm cov organic additives los ntawm cov loj hlob rau cov qoob loo. Ntxiv mus, nws yuav tsum coj mus rau hauv tus account lub hom chiv siv. Piv txwv li, rau ib tug nruab nrab koob tshuaj zaub yog 40-60 (thaum nyob rau hauv lub xub ntiag ntawm ib tug yooj yim) los yog 20-30 grams tauj ib 1 m ² (Yog hais tias koj npaj yuav siv ob superphosphate). Daim ntawv thov ntawm chiv pom zoo nyob rau hauv tej thaj chaw nyob qhov twg cov tawm los nyob rau ntawm cov leej faj cov ntsiab lus ntawm cov av, uas yog ib qho tseem ceeb thaum loj hlob oleaginous, cereals thiab legumes. Superphosphate ua kom zoo dua nyob rau hauv kab - nyob rau hauv cov ntaub ntawv no, lub siv tus nqi ntawm phosphorus yog ob peb lub sij hawm ntau dua nyob rau hauv kev sib piv nrog across ua ntej plowing. Nyob rau tib lub sij hawm tsim txom cov ntaub ntawv ntawm lub chiv yog tsis tsim nyog. Tshwj xeeb tshaj yog yog hais tias peb coj mus rau hauv tus account uas nyob rau hauv 2-3 lub xyoo ntawm phosphorus assimilation tshem superphosphate yog kwv yees li 40%.

Muaj pes tsawg leeg thiab hom

Nyob rau hauv tas li ntawd rau nws cov ntsiab tivthaiv, tam sim no chiv kuj muaj nitrogen, sulfur, magnesium thiab calcium. Nyob ntawm seb qhov feem pua ntawm assimilable nrog / x kev lis kev cai phosphorus, superphosphate yuav ua tau tej yam yooj yim, muab ob npaug rau thiab enriched. Xeem nyob rau cov qauv occupies ib nrab txoj hauj lwm ntawm thawj ob tug. Rau hnub tim, qhov no chiv yuav yuav nyob rau hauv cov hmoov los yog nyob rau hauv granular daim ntawv. Nyob rau hauv thawj cov ntaub ntawv, daim ntawv thov ntawm superphosphate neeg raug nqi ntau heev cheaper. Vim hais tias ntawm nws yooj yim nws qhov no zoo ntawm chiv yog zoo tshaj plaws rau qhov kev npaj ntawm composts. Nyob rau lwm cov tes, ib tug hmoov npaj, tej zaum, theem tsis zoo tshaj granulated superphosphate. Siv ntawm lub yav tas kom tsis txhob muaj caking, muaj zoo dissipated, thiab phosphorus nws muaj ntau (mus txog rau 22%).
