The bigger the radish leaves, the smaller the radish: the ratio of carbon to nitrogen in the early stage of vegetative growth is beneficial to the growth of leaves, and the high nitrogen content in the later stage makes the aboveground parts grow in vain, and the underground parts cannot accumulate nutrients. Radish Cruciferae Radish is biennial or millet, with a height of 20- 100 cm, straight roots, rectangles, spheres or cones, and green, white or red skins.
