萝卜属于半耐寒性蔬菜,生长期温度范围为5℃～25℃,地上部生长的最适温度为15℃～20℃,地下部生长的最适温度为13℃～18℃。萝卜的根系入土层较浅,故耐旱能力弱,土壤含水量以70％～80％为宜。萝卜生长一般要求中等光照强度,在长日照条件下容易引起抽薹。日平均温度10℃～12℃的冷凉
Radish belongs to half-hardy vegetables, the temperature range of growth stage is 5 ℃ ~ 25 ℃, the optimum temperature of shoot growth is 15 ℃ ~ 20 ℃, and the optimum temperature of underground growth is 13 ℃ ~ 18 ℃. Roots of radish into the soil is shallow, so weak drought tolerance, soil moisture content of 70% to 80% is appropriate. Radish growth generally require moderate light intensity, easy to cause bolting under long-day conditions. The average daily temperature of 10 ℃ ~ 12 ℃ cold
