Biennial herb, plant height 50-100cm. Smooth is Creme. Root hypertrophy, nearly conical, diameter 2-3cm, long 20-30cm, khaki-colored surface, with short stripes and a few fibrous roots. Basal leaf rosette Radix special for seeds, oblong blade to wide oblanceolate, long 5-15cm, width 1.5-4cm, apex obtuse, margin entire, or slightly shallow wave tooth, round leaves ear or obvious; the top of the stem and leaf width strip, entire, sessile. Or axillary racemes, composed in the top branches conical; sepals 4, broadly ovate or broadly lanceolate, long 2-3mm; petals 4, yellow, wide wedge, long 3-4mm, apex truncate margin entire, base with no obvious short claw; stamens 6,4 long 2 short and long stamens long 3-3.2mm Radix seed supply, short stamens long 2-2.2mm; pistil 1, ovary nearly cylindrical, style boundaries obvious, stigma truncated. Short pod nearly oblong, flat, glabrous, margin membranous wings, especially the ends of the wide-winged fruit flap with the veins. Seeds 1, oblong, light brown. Flowering from April to May, fruiting from May to June. Radix on climate and soil conditions adaptable, resistant to cold, like warm, but the fear of water damage Radix seed origin, the majority of China's Yangtze River basin and northern areas could grow normally. Seeds germinate easily, are sprouting within the range of 15C ~ 30C good germination rate is generally more than 80%, seed longevity for l ~ 2 years. Radix normal growth and development must go through the winter cold stage, can only flowering seed, so the production will take advantage of this feature, take the spring or summer sowing, harvesting the leaves and then dig their roots, planting time is 5 to 7 months. As the normal growth period cultivation, leaving only for breeding. Adaptable, the natural environment and soil strict, cold, likes the warm, deep-rooted plants should be planted deep in the soil loose and fertile, sandy loam, avoid low-lying land, easy to mess root, so pay attention to drainage during the rainy season.
