Kodi physiological function of rare earth pa zomera ndi chiyani?

Kafukufuku pa zotsatira zazosowa zapadziko lapansi on zomera physiology wasonyeza kuti osowa nthaka zinthu akhoza kuonjezera zili chlorophyll ndi photosynthetic mlingo mu mbewu; Kulimbikitsa kwambiri mizu ya zomera ndikufulumizitsa kukula kwa mizu; Kulimbitsa mayamwidwe ayoni ntchito ndi zokhudza thupi ntchito ya mizu, ndi bwanji ntchito zomera asafe fixation ndi michere ina; Zinapezeka kudzera mu kufufuza kwa atomiki kuti zinthu zosowa zapadziko lapansi zimatha kulimbikitsa kuyamwa ndi kunyamula nayitrogeni, phosphorous, ndi potaziyamu ndi zomera. Zinthu zosawerengeka zapadziko lapansi zimatha kulimbikitsa kukula ndi kukula kwa mbewu, komanso kukhala ndi zotsatira zabwino pa zokolola.

Zosowa zapadziko lapansikulimbikitsa kwambiri kumera kwa mbewu. Mlingo woyenera wa mankhwala osowa padziko lapansi olimbikitsa kumera kwa mbeu ndi 0.02-0.2 magalamu pa kilogalamu (2 pounds). Zinthu zosawerengeka zapadziko lapansi zimathanso kulimbikitsa kukula kwa zomera, kulimbikitsa kukula kwa zomera zatsopano ndi kulemera kwatsopano, ndipo zimakhala ndi zotsatira zolimbikitsa pakukula kwa tirigu, mpunga, chimanga, ndi nyemba zomwe zimakhala kuyambira 5 mpaka 100 ppm. Pamalo oyenerera, amakhudza kukula kwa mizu ya zomera, tsinde, ndi masamba, ndipo chodziwikiratu ndicho kukula kwa masamba. Zinthu zosawerengeka zapadziko lapansi zimakhudza kwambiri mizu ya zomera ndi kukula kwa mizu, ndipo ndende yabwino kwambiri yolimbikitsira mizu ndi 0.1-1ppm. Pamwamba pa izi, kuletsa kumachitika. Dothi losawerengeka limalimbikitsa kukula kwa mizu makamaka polimbikitsa kupezeka kwa mizu yodziwikiratu, zomwe zimakhudza kusiyanasiyana kwa maselo ndi mizu ya morphogenesis. Kuonjezera zinthu zachilendo zapadziko lapansi pakukula kwa mizu kumatha kulimbikitsa kuyamwa kwa phosphorous ndi mizu. Mulingo woyenera kwambiri pakuyamwa kwa mizu ya phosphorous ndi 0.1 ~ 1. Oppm; Ikhoza kulimbikitsanso kuyamwa kwa nayitrogeni ndi potaziyamu. Osowa lapansi zinthu akhoza kumapangitsanso zokhudza thupi ntchito ya mizu, kuwonetseredwa ndi zolimbikitsa exudation wa muzu kuyamwa ndi utithandize puloteni ntchito mu mizu. Zinthu zosowa zapadziko lapansi zimagwirizana kwambiri ndi photosynthesis ya zomera ndipo zimatha kulimbikitsa kukonza kwa zomera za carbon dioxide photosynthesis, potero kumapangitsa kuti photosynthesis ikhale bwino. Kuyeseraku kunawonetsa kuti kuchuluka kwa chlorophyll m'masamba a zomera zomwe zimathandizidwa ndi nthaka yosowa kunawonjezeka, makamaka kuchuluka kwa chlorophyll A, zomwe zimapangitsa kuti chiŵerengero cha chlorophyll A / B chiwonjezeke.

Komanso, kupopera mbewu mankhwalawa osowa lapansi zinthu kungathenso kuonjezera ntchito ya nitrate reductase mu zomera, kuchepetsa kwambiri zili nitrate asafe mu thupi. Zotsatira za zinthu zosowa zapadziko lapansi pakukonzekera kwa nayitrogeni zomwe zimaperekedwa ndi tinthu tating'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'onoting'ono zimawonekera pakuwonjezera kuchuluka kwa tinthu tating'onoting'ono komanso kukonza kwa nayitrogeni. Zinthu zosawerengeka zapadziko lapansi zimathanso kukulitsa luso lowongolera ma cytoplasmic nuclei kuti ma electrolyte atayike, potero amathandizira kuti mbewuyo isavutike ndi chilala, mchere, ndi alkali.
