Ntxiv ntawm qhov tseem ceeb ntawm seedlings yog ib qho tseem ceeb heev mob rau lub cog kev loj hlob ntawm cov tub ntxhais hluas cov nroj tsuag. Nrog tsawg illumination nyob rau hauv cov nroj tsuag, tus txheej txheem ntawm photosynthesis yog lethargic, thiaj li hais tias seedlings loj hlob qeeb thiab feem ntau muaj mob. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xaiv qhov tseeb teeb rau me nyuam yaus teeb. Xav txog cov kev xaiv muaj hnub no kom nkag siab tias yuav ua haujlwm zoo li cas.
Dab tsi ntawm lub teeb uas yuav tsum tau ua kom pom kev yos hav zoov?
Teeb txaij siv rau seedling seedlings yog cov ntau. Cov ntsiab lus tseem ceeb yog sawv cev ntawm cov hom nram qab no:
- Lub backlighting ntawm seedlings by daylight mercury yaj tsis sufficiently zoo, vim hais tias lub teeb txawb dawb lub teeb, uas yog tsis tseem ceeb rau cov nroj tsuag. Lawv xav tau ntau tshaj qhov liab thiab liab liab ntawm cov spectrum, uas tsis tuaj yeem muab tau los ntawm lub teeb nruab hnub nrig.
- Lub backlighting ntawm seedlings nrog ib tug conventional incandescent teeb yog tsis tsuas yog siv tsis tau rau seedling, tab sis kuj uneconomical hais txog hluav taws xob noj. Cov kev lag luam no tsuas hloov 5% ntawm lawv lub zog mus rau hauv lub teeb, so rau hauv thermal hluav taws xob. Los ntawm no seedling yog ncav us txog, Burns, dries.
- Cov roj teeb ntawm "Suav" muaj zog tuaj yeem siv tau rau cov ntoo. Feem ntau cov nyiam yog xws li ntau yam xws li DNaZ, DNaT, DRiZ thiab lawv ua ke kom tau tag nrho spectrum. Qhov zoo ntawm cov roj teeb nyob rau hauv lawv cov muaj zog, kev ua haujlwm siab, muaj lub teeb nyob ruaj khov. Disadvantages - tus nqi siab thiab xav tau kev txhim kho kev ntxawg.
- Fluorescent teeb - lub illumination ntawm seedlings los ntawm lawv yog heev ntau. Txawm li cas los xij, nws yuav tsum raug coj mus rau hauv tus account tias lawv tsis muaj zog txaus rau lub hom phiaj no, dhau mus, tsis muaj kev liab txaus hauv lawv cov spectrum. Rau qhov tseem ceeb ntawm cov noob qoob loo nrog cov roj teeb, lawv yuav tsum tau muab tso rau ntawm ib qhov siab ntawm 15-30 cm, thiab rau teeb pom kev zoo ib lub dab hluav taws xob nrog seedlings 2 yaj ntawm 40 W txhua tus yuav tsum xav tau.
- Phytolamp (photoluminescent teeb) - eco-tus phooj ywg, siv tau rau kev yub, ua haujlwm, kev cog lus thiab kev nyab xeeb. Txawm li cas los xij, nws tawm ib lub lilac-pink glow, uas khaus lub qhov muag ntawm ib tug neeg, ua rau mob taub hau. Yog li ntawd, nws tsis pom zoo siv xws li yaj tsis muaj reflectors.

Cov roj teeb lawv tus kheej yog cov muaj zog, muaj kev ua tau zoo, thiab cov spectrum ntawm lub cev tau yooj yim kho ntawm ntau theem ntawm seedling kev loj hlob.
