Zhangye Prefecture in Gansu Province is located in the middle of Hexi Corridor, Gansu Province, adequate sunshine, long frost-free period, large temperature difference between day and night, good irrigation conditions, which will benefit the growth of sugar beet and sugar accumulation. However, in recent years, blackfoot disease is serious in the seedling stage, with the incidence rate of 15% -20% in normal years, 50% -70% in severe years and as high as 90% in individual plots.
