Dub, raws li tau hais tseg, yog siv los ua ib qho npog npog, thiab tseem muaj xim dub thiab dawb spunbond uas yog muab cov khoom ntawm npog thiab cov ntaub ntawv pov thawj. Tsis tas li ntawd, qee qhov chaw lag luam muaj ntawv ci thiab muaj zog dua. Cov qub pib ua kev loj hlob los ntawm kev xav txog hnub ci rau ntawm cov nroj tsuag, thaum lub caij nyoog kawg yog npaj rau greenhouses thiab hotbeds ntawm nce zog.
