Sugar beet in the process of phylogeny, the constant assimilation of external conditions, forming a series of biological characteristics. People through their own production practices, and gradually understand and master these characteristics, so as to improve cultivation techniques to make it as much as possible to meet the characteristics of beet characteristics in order to achieve high yield and quality beets. Small beet seeds, grain weight of only 7 grams, seed germination more water, about 1.5 times the weight of bulbs above the cotyledons shaft top soil is weak, is the top soil of soybeans
