Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau dua ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov cog: nitrogen , phosphorus , thiab poov tshuaj . Qhov tseem ceeb thib ob yog cov ntsiab lus leej faj , magnesium, thiab calcium.
Yog li ntawd, dab tsi yog cov ntsiab lus pom nyob rau hauv chiv?
Nitrogen , phosphorus thiab poov tshuaj, los yog NPK, yog "Big 3" cov khoom noj khoom haus tseem ceeb hauv kev lag luam chiv. Txhua yam ntawm cov as-ham tseem ceeb no ua lub luag haujlwm tseem ceeb hauv cov zaub mov ntawm cov nroj tsuag. Nitrogen suav tias yog cov khoom noj tseem ceeb tshaj plaws, thiab cov nroj tsuag nqus tau ntau dua nitrogen tshaj lwm yam.
Tsis tas li ntawd, cov ntsiab lus twg tseem ceeb tshaj plaws rau cov nroj tsuag? Tsawg kawg yog 17 lub ntsiab lus paub tias yog cov khoom noj tseem ceeb rau cov nroj tsuag. Nyob rau hauv tus nqi loj, cov av muab nitrogen, phosphorus, potassium, calcium, magnesium , thiab sulfur; cov no feem ntau hu ua macronutrients.
Xav txog qhov no, dab tsi yog chiv ua los ntawm?
Feem ntau, chiv yog muaj li ntawm nitrogen, phosphorus, thiab potassium compounds. Lawv kuj muaj cov kab kawm uas txhim kho kev loj hlob ntawm cov nroj tsuag. Cov khoom tseem ceeb hauv chiv yog cov as-ham uas tseem ceeb rau cov nroj tsuag loj hlob. Cov nroj tsuag siv nitrogen hauv kev sib txuas ntawm cov protein, nucleic acids, thiab cov tshuaj hormones.
Cov npe ntawm cov chiv yog dab tsi?
Daim ntawv teev cov tshuaj chiv ua liaj ua teb
- Urea.
- Ammonium nitrate.
- Ammonium sulfate.
- Calcium nitrate.
- Diammonium Phosphate.
- Monoammonium phosphate.
- Triple Super Phosphate.
- Potassium nitrate.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Lub ntsiab lus twg yog pom nyob rau hauv qhov tsuas yog nyob rau hauv tebchaw quizlet?
Halogens yeej ib txwm pom nyob rau hauv cov xwm txheej incompounds vim hais tias halogens yog heev reactivenonmetals
Qhov twg ntawm cov ntsiab lus hauv qab no yog qhov tseem ceeb ntawm kev sib txawv?
Lub hom phiaj tseem ceeb ntawm kev sib txawv yog cov hauv qab no: hnub nyoog, haiv neeg, poj niam txiv neej, lub cev muaj peev xwm / zoo, haiv neeg thiab kev sib deev
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
