Legumes muaj peev xwm tsim tau kev sib raug zoo nrog nitrogen-kho av kab mob hu ua rhizobia. Qhov tshwm sim ntawm qhov symbiosis no yog tsim cov nodules ntawm cov nroj tsuag hauv paus, nyob rau hauv uas cov kab mob yuav hloov atmospheric nitrogen rau hauv ammonia uas yuav siv tau los ntawm cov nroj tsuag.
Yuav ua li cas cov nroj tsuag leguminous hloov nitrogen?
Cov hauv paus ntawm cov nroj tsuag leguminous muaj nitrogen kho cov kab mob xws li Rhizobium, cov kab mob no siv los hloov atmospheric nitrogen rau nitrate kom cov nroj tsuag tuaj yeem nqus cov nitrate thiab siv lawv. Yog li cov nroj tsuag leguminous pab hauv replenishing nitrogen hauv av.
Puas nitrogen kho tau los ntawm cov nroj tsuag?
Stage 1: Nitrogen Fixation
Yuav tsum tau siv los ntawm cov nroj tsuag, N2 yuav tsum tau hloov los ntawm cov txheej txheem hu ua nitrogen fixation. Fixation hloov nitrogen nyob rau hauv qhov chaw rau hauv cov ntaub ntawv uas cov nroj tsuag tuaj yeem nqus tau los ntawm lawv cov hauv paus system.
Yuav ua li cas tsiaj leguminous nroj tsuag kho nitrogen?
Ob yam ntawm nitrogen-fixing microorganisms raug lees paub: dawb-nyob (nonsymbiotic) kab mob, suav nrog cyanobacteria (los yog xiav-ntsuab algae) Anabaena thiab Nostoc thiab genera xws li Azotobacter, Beijerinckia, thiab Clostridium; thiab mutualistic (symbiotic) kab mob xws li Rhizobium, cuam tshuam nrog cov nroj tsuag leguminous, …
cov nroj tsuag leguminous pab nitrogen fixation li cas?
cov nroj tsuag Leguminous muaj cov kab mob rhizobium, uas nyob hauv nwshauv paus nodules. Cov no cov kab mob no hloov cov cua nitrogen rau hauv nitrites thiab nitratesuas tuaj yeem siv tau los ntawm cov nroj tsuag thiab yog li, pab kho nitrogen.

Cov dej mos puas ua rau cov nroj tsuag?
Cov sodium hauv cov dej softened tiag tiag cuam tshuam nrog cov dej tshuav hauvcov nroj tsuag thiab tuaj yeem tua cov nroj tsuag los ntawm "dag" lawv xav tias lawv tau haus dej ntau dua li lawv muaj. Softened dej yeej tseem ceeb ua rau cov nroj tsuag hauv koj lub vaj kom tuag nqhis dej.
Cov nroj tsuag hauv dej puas tsim cov pa oxygen?
Nyob rau hauv dej ib puag ncig, cov nroj tsuag tsis muaj ntab ntab uas paub tias yog algae, thiab cov nroj tsuag loj dua (macrophytes), tso oxygen ncaj qha rau hauv dej qhov twg nws siv los ntawm tsiaj thiab lwm yam kab mob, nrog rau cov nroj tsuag lawv tus kheej.
Puas yog ammoniacal nitrogen zoo rau cov nroj tsuag?
The H + cation ces reacts nrog qhov loj hlob nruab nrab ua rau txo qis hauv nws cov pH. Qhov siab dua qhov concentration ntawm ammoniacal nitrogen hauv cov chiv, qhov ntau dua qhov cuam tshuam nws tau txo qis qhov loj hlob nruab nrab pH. Ammoniacal nitrogen kuj tuaj yeem muaj rau cov nroj tsuag los ntawm cov txheej txheem hu ua nitrification.
Puas yog cov nroj tsuag carnivorous yog cov tsim khoom lossis cov neeg siv khoom?
As producers, cov nroj tsuag tsim lub hauv paus ntawm yuav luag txhua cov khoom noj hauv ntiaj teb. Carnivorous nroj tsuag zoo li "tig rooj" thaum lawv ua raws li cov neeg siv khoom, gobbling kab, qav, thiab cov tsiaj me me. Puas yog Venus flytrap yog tus neeg siv khoom thiab tsim khoom?
Cov nroj tsuag sab hauv tsev hauv cov nroj tsuag?
