Yuav ua li cas yog fertilizer?

Raws li ib txoj kev ua tag nrho cov niaj hnub compound chiv raug muab faib ua mixed, nyuaj thiab tsis yooj-mixed. Qhov thib ob pab pawg neeg tau txais attribute xws li ammophos, poov tshuaj nitrate, diammonium phosphate. Cov tshuaj no yog tau los ntawm kev sib raug zoo ntawm cov tshuaj. Cov khoom xyaw ntawm cov kua thiab cov khoom chiv ua kom paub cov qauv kab, tshuaj ntsuab thiab qee tshuaj tua kab.

Combined (complex) tov complex chiv, uas tau txais raws li ib tug ntawm ib tug txheej txheem technological. Xws li chemicals nyob rau hauv ib qho pellet muaj ob los yog peb qho as ham tseem ceeb rau kev loj hlob ntawm cov nroj tsuag, nyob rau hauv daim ntawv ntawm cov sib txuas. Kev sib xyaw muaj xws li: nitrophos thiab nitrophos, nitroammophoska thiab nitroammophos, potassium thiab ammonium polyphosphates, carboammophoses, kua sib tov sib xyaw.

Mixed yog lub compositions ntawm yooj yim chiv, uas tau muab nyob rau hauv tus txheej txheem ntawm qhuav mixing.

Txoj kev sib xyaw thiab sib xyaw ua ke yog cov yeeb yaj kiab los ntawm cov ntsiab lus ntawm cov as-ham, thaum lawv tau siv nyiaj ntau heev.

Dua li ntawm tag nrho nws qhov kev vam meej, ua cov chiv muaj ib qho teeb meem loj - cov kev faib tawm hauv NPK cov ntsiab lus nyob rau hauv lawv sib txawv nyob rau hauv theej vam txwv.

Hauv kev npaj, qhov feem pua ntawm cov ntsiab lus ntawm cov ntsiab lus yog feem ntau nruj pom, tab sis, yog tias qee yam kev hloov, ces, ua cov lus yooj yim, cov kev hloov no tuaj yeem ua nws tus kheej. Piv txwv li, yog tias cov chiv ua rau cov zaub muaj nitrogen hauv cov khoom tsis txaus, ib qho tshuaj yooj yim uas muaj nitrogen cov ntsiab lus tau ntxiv rau lawv, tab sis tsuas yog cov kev cob qhia agrotechnics tuaj yeem txo cov ntsiab lus ntawm kev tivthaiv.

Thaum lub sij hawm ntawm kev khawb lub ntiaj teb nyob rau hauv lub caij nplooj ntoos hlav los yog lub caij nplooj zeeg lub sij hawm rau zoo kawm av minerals yuav siv formulations uas muaj concentration ntawm ib yam khoom xws li calcium carbonate, uas yog zoo dampens acidity. Qhov no tseem ceeb heev rau cov cheeb tsam uas muaj txiv lws suav nyob.

Complex fertilizer rau txiv lws suav nyob rau hauv ib tug seedling loj hlob txoj kev yog ua thaum cog seedlings nyob rau hauv cov av. 500 grams humus tov nrog ib tug tablespoon ntawm tshauv thiab ib teaspoon ntawm superphosphate yog ntxiv rau qhov zoo rau cov nroj tsuag. Sab saum toj hnav khaub ncaws ntawm lws suav seedlings yuav nqa tawm twb kaum hnub tom qab cog thiab rooting.

Thawj lub sij hawm txiv lws suav yog pub nrog mullein, thiab ua chiv yuav nkag tau thaum lub sij hawm thib ob zoo li tus txheej txheem.

Ob zaug thiab cov pa superphosphate yog cov feem nrov thiab hom tshuaj siv los cog cov lws suav. Cov tshuaj no muaj xws li: phosphorus, calcium, sulfur, magnesium thiab nitrogen. Txhua qhov ntawm cov ntsiab lus tau nws tus kheej tseem ceeb. Piv txwv li, calcium zoo lowers tus acidity ntawm cov av, thiab magnesium yog ib tug yuav tsum Solanaceae nroj tsuag rau cov qub thiab active kev loj hlob. Ua tiav chiv feem ntau yog ua nyob rau hauv daim ntawv ntawm hmoov los yog granules.
