Carrots require high illumination, especially during fleshy root hypertrophy, so we must ensure sufficient illumination, otherwise the yield will be reduced and the quality will be affected. During planting, the soil should be moist, especially during germination. If the soil is too dry during plant formation, the fleshy roots will become smaller, rougher, irregular in shape and hard in texture.
