Lub caij nplooj zeeg cog feem ntau siv rau qhov no. Caij nplooj ntoos hlav cog paj noob yuav tsum tau kho kom germination yuav siv qhov chaw thawj lub caij loj hlob. Hu rau koj tus neeg muag khoom kom paub meej. Ntawm qhov chaw me me, noob tuaj yeem muab tes sown thiab maj mam raked rau hauv av txog 1/8 nti tob.
Dab tsi yog prairies siv rau?
