Fertilizers muab cov nroj tsuag muaj txiaj ntsig zoo uas, ntawm lwm yam, txhawb kev loj hlob lossis tiv thaiv kab tsuag thiab huab cua, kom lawv xis nyob hauv lawv lub tsev.
Fertilizer
Fertilizers los yog chiv muaj nyob rau hauv ntau hom: kua, khoom, granules los yog nyob rau hauv daim ntawv ntawm sticks. Ib qho kev sib txawv kuj yog tsim los ntawm qhov hu ua universal chiv thiab tshwj xeeb chiv. Fertilizers raug cais ntxiv raws li lawv cov khoom. Ib qho kev sib txawv yog tsim los ntawm kev siv cov organic thiab ntxhia. Potassium nitrate chiv yog cov ntxhia chiv.
Tshuaj muaj pes tsawg leeg thiab cov khoom
Potassium nitrate yog poov tshuaj ntsev ntawm nitric acid. Tias yog vim li cas ntsev feem ntau hu ua s altpeter los yog potassium s altpeter. Nyob rau hauv cov xwm, nws tshwm sim tsuas yog nyob rau hauv Tuam Tshoj thiab Southeast Asia, tab sis hnub no nws yog tsuas yog tau synthetically los ntawm nitric acid. Cov kua qaub nws tus kheej yog ib yam khoom tsis muaj zog, qhov ruaj khov tshaj plaws hauv cov kua qaub ntawm nitrogen. Lawv cov ntsev hu ua nitrates. Kev hais lus tshuaj, potassium nitrate muaj cov ntsiab lus no:
- Oxygen (O)
- Nitrogen (N)
- Potassium (K)
Cov tshuaj formula yog KNO3. Cov chiv yog cov ntxhia thiab nitrogen chiv tib lub sijhawm. S altpeter tsim cov xim tsis muaj kob uas yaj hauv dej. Potassium nitrate dissolves zoo tshaj plaws hauv dej sov. Potassium s altpeter tsis tsuas yog pom nyob rau hauv cov nroj tsuag chiv. Raws li E 252 nws kuj tseem siv los kho ntsev kom khaws zaub mov; Tsis tas li ntawd, potassium nitrate yog cov khoom tseem ceeb hauv cov hmoov dub. Thiab nws tseem pom muaj nyob rau hauv cov tshuaj txhuam hniav rau cov hniav rhiab.
Potassium nitrate yog hygroscopic, tab sis nws tsis khi dej zoo li sodium nitrates, piv txwv li. Txij li thaum potassium nitrate yog me ntsis oxidizing, ntshiab KNO3 yuav tsum tau ua tib zoo saib xyuas.
Siv li cog chiv
Potassium, nrog rau nitrogen thiab phosphorus, yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov nroj tsuag. Hauv lwm lo lus, potassium yog qhov tseem ceeb rau kev ciaj sia ntawm txhua tsob nroj, ua lag luam lossis ornamental, vim tias cov nroj tsuag xav tau cov ntxhia los nqus dej. Tias yog vim li cas sab hauv tsev lossis potted nroj tsuag tshwj xeeb yuav tsum tau muab cov khoom txaus ntawm lawv. Ntawm chav kawm, tus nqi tiag tiag xav tau nyob ntawm tus kheej cov nroj tsuag. Cov nroj tsuag uas xav tau cov poov tshuaj siab muaj xws li:
- Tomatoes
- Pumpkins
- Cucumbers
- Qos yaj ywm
- Aquatic nroj tsuag (Aquarium)
Cov nroj tsuag uas cog rau hauv lub lauj kaub lossis lub thoob xav tau qhov nruab nrab ntawm 49 grams ntawm poov tshuaj ib kilogram ntawm av.
Tip:
Rau cov nroj tsuag cog, kev tshuaj xyuas av yog pom zoo ua ntej siv cov poov tshuaj nitrate, vim tias cov poov tshuaj ntau dhau tuaj yeem ua rau muaj kev phom sij rau cov nroj tsuag.
Potassium pab cov nroj tsuag nqus lwm cov as-ham zoo dua. Qhov no txhais tau hais tias lawv muaj kev vam meej zoo dua thiab ntau dua tuaj yeem ua tiav los ntawm cov qoob loo. Tab sis cov khoom zoo ntawm cov poov tshuaj mus ntxiv:
- Txhim kho cov txiv hmab txiv ntoo khov thiab xim
- Txhim kho Frost tiv thaiv los ntawm kev tswj cov dej sib npaug
- promotes lub caij ntuj no hardiness
- Txoj kev tiv thaiv kab mob los ntawm kev txhim kho cov phab ntsa cell
- Kev tiv thaiv kab mob fungal
- Txhawb nqa cov khoom tsim tawm
Yog li ntawd cov nroj tsuag tuaj yeem nqus tau cov poov tshuaj zoo dua, lawv xav tau nitrate nitrogen. Nws tuaj yeem absorbed tam sim ntawd los ntawm cov nroj tsuag thiab nyob rau hauv lem txhawb kev loj hlob. Ntxiv nrog rau cov poov tshuaj, nitrate nitrogen kuj ua kom cov calcium thiab magnesium tuaj yeem nqus tau zoo dua los ntawm cov nroj tsuag.
Potassium deficiency thiab ntau dhau
Fertilizers feem ntau yog siv los muab cov nroj tsuag nrog cov as-ham tsim nyog. Raws li cov zaub mov cog, ntxiv rau dej thiab carbon dioxide, lawv yuav tsum tau muab tsis tu ncua thaum lub caij loj hlob. Tsis muab cov as-ham tuaj yeem ua rau cov tsos mob tsis txaus. Koj paub qhov tsis muaj poov tshuaj:
- nplooj bleached nyob rau hauv qhov chaw (chlorosis), yellowing
- xim daj ntawm nplooj (necrosis, tuag ntawm nplooj cov ntaub so ntswg)
- muab nplooj tuag ntawm ntug
- txoj kev ruaj ntseg ntawm cov nroj tsuag
- Growth Disorders
- cov txiv hmab txiv ntoo tawg (tshwj xeeb yog txiv lws suav)
Zuag qhia tag nrho, cov nroj tsuag zoo li qaug zog thaum muaj cov poov tshuaj tsis txaus. Cov poov tshuaj ntau dhau ntawm cov av kuj tuaj yeem ua rau cov hauv paus hniav puas tsuaj, ua rau cov hauv paus hniav hlawv, ua rau lawv tuag.
Tip:
Cov qauv tsis zoo ntawm cov av yog qhov qhia tau zoo ntawm cov poov tshuaj ntau dhau hauv cov av.
Txawm hais tias cov poov tshuaj yog qhov tsim nyog rau cov nroj tsuag ciaj sia, ntau tshaj ntawm cov poov tshuaj tsuas yog tsim kev puas tsuaj rau cov nroj tsuag raws li qhov tsis txaus ntawm cov khoom noj tseem ceeb. Yog tias cov nroj tsuag tau txais cov poov tshuaj ntau dhau lawm, lawv tsis tuaj yeem nqus cov khoom tseem ceeb magnesium ntxiv lawm, uas tsim nyog rau ntau cov txheej txheem metabolic hauv cov nroj tsuag, suav nrog photosynthesis. Nyob rau tib lub sijhawm, ntau tshaj ntawm magnesium inhibits kev nqus ntawm potassium. Kuj tseem muaj kev cuam tshuam thaum nqus nrog calcium. Cov poov tshuaj ntau dhau tuaj yeem ua rau nws nyuaj rau nqus, uas ua rau txo qis kev loj hlob.
Tip:
Yog tias cov nroj tsuag raug kev txom nyem los ntawm cov poov tshuaj ntau dhau, ntxiv cov khoom noj ntxiv yuav tsum raug ncua rau lub sijhawm. Tsis tas li ntawd, tej zaum koj yuav tau muab magnesium ntxiv kom coj cov nroj tsuag rov qab mus rau qhov sib npaug.
Potassium nitrate chiv hauv khw
Potassium nitrate chiv tuaj yeem yuav los ntawm cov khw muag khoom kho vajtse lossis cov khw muag khoom tshwj xeeb. Cov chiv tshwj xeeb feem ntau tuaj yeem pom nyob rau hauv lub npe NK chiv. "NK" sawv cev rau cov tshuaj uas nws muaj, nitrate nitrogen thiab potassium. Yog li ntawd cov poov tshuaj nitrate kuj tuaj yeem siv los tsim cov khoom tawg thiab lwm yam kev sib xyaw pyrotechnic, koj tuaj yeem nug koj tus ID thaum yuav khoom. Universal chiv muaj nyob rau hauv lub npe N-K-P chiv. Lawv muaj cov ntsiab lus tseem ceeb nitrogen (N), potassium (K) thiab phosphorus (P). Qhov kev faib ua feem ntawm tus kheej cov as-ham txawv nyob ntawm cov chiv.
Ntxiv nrog rau cov chiv thoob ntiaj teb, cov poov tshuaj kuj tuaj yeem pom nyob rau hauv cov npe hu ua potassium chiv. Ntxiv nrog rau cov poov tshuaj, cov chiv no kuj muaj magnesium, sulfur lossis sodium. Muaj cov poov tshuaj ntsev tshwj xeeb rau cov nroj tsuag dej hauv thoob dej yug ntses. Lawv muaj nyob rau hauv daim ntawv kua tsis tau tsuas yog nyob rau hauv lub khw muag khoom kho vajtse, tab sis kuj nyob rau hauv lub khw muag tsiaj. Koj yuav tsum tsis txhob siv cov khoom lag luam N-K-P chiv rau cov nroj tsuag thoob dej yug ntses. Tej zaum lawv yuav muaj cov ntsiab lus tooj liab uas tsis paub meej, uas yog qhov txaus ntshai, yog tias tsis tuag, rau ntses thiab qwj.
Tip:
Nws feem ntau hais tias potassium nitrate kuj tuaj yeem yuav los ntawm lub tsev muag tshuaj uas ntseeg siab. Txij li thaum nyob rau hauv rooj plaub no koj feem ntau cuam tshuam nrog "tus tsim foob pob", qhov chaw ntawm cov khoom siv no tsis pom zoo, tshwj xeeb tshaj yog nyob rau hnub no thiab hnub nyoog, rau qhov laj thawj zoo.
