Feem ntau ntawm cov zaub thiab paj cov qoob loo nyob rau hauv peb cov latitudes yog cog los ntawm seedlings. Noob yog sown nyob rau hauv Lub ib hlis ntuj-Lub ob hlis ntuj, thaum lub teeb hnub tseem heev luv luv, thiab xws li tej yam kev mob tsis txaus rau high school qib photosynthesis. Yog li, cov neeg ua liaj ua teb siv dag teeb pom kev zoo thaum loj hlob seedlings. Nws muaj peev xwm ua tau ntau yam: raws li txoj cai, cov no yog cov phytolamps tshwj xeeb, thiab cov mercury, sodium (pa thiab metalloallogenic), luminescent thiab teeb roj teeb rau lub qhov rais hauv qhov rais. Cov roj teeb rau cov laj thawj no tsis siv, vim hais tias lawv yog uneconomical heev thiab tsis ntau lub teeb ua cua sov, thiab me me yoog tua tau yooj yim tau hlawv.
Feem ntau niaj hnub no siv ob hom - phytolamps thiab LED teeb pom kev zoo. Txawm li cas los xij, phytolamps yeej kim heev, lawv yuav them cov nqi yog tias koj cog nroj tsuag tom qab muag. Tab sis lub illumination ntawm seedlings nyob rau ntawm lub tsev los ntawm LED teeb tau ua ntau thoob plaws vim cov nram qab no zoo.
Zoo ntawm LED teeb rau qhov tseem ceeb ntawm seedlings
Nyob rau hauv kev sib piv nrog rau lwm yam ntawm lub teeb rau seedlings, LED backlighting muaj ntau yam hnyav "pluses":
- kev lag luam thiab durability ntawm tsawg voltage, tsawg zog noj thiab tsis xav hloov burnt tawm qhov muag teev;
- cov kev xaiv ntawm lub spectrum ntawm lub teeb thiab ua ke ntawm qhov tseem ceeb tshaj plaws ntawm lawv (xiav thiab liab);
- kev hloov kho ntawm kev siv lub teeb taws;
- Cov LEDs tsis yoov thiab tsis ua daim duab hluav taws xob los sis hluav taws xob ultraviolet;
- Cov teeb roj teeb tsis muaj roj, mercury thiab lwm yam tshuaj lom neeg, tsis ua rau muaj teeb meem nrog lawv qhov chaw pov tseg;
- Yog tias qhov kev xav tau, lub teeb taws tuaj yeem raug tsim tawm ntawm nws tus kheej. Qhov chaw ntawm lub LED strips rau qib siab seedling teeb yuav tsum muaj ib tug ratio ntawm 2: 1 (2 liab, 1 xiav, 1 liab, 1 xiav, thiab lwm yam).
