In order to strengthen the beet spring production guidance, the National Agricultural Technology Center, in conjunction with the relevant experts, has formulated and formulated the “Guidance on Beet Spring Production Technology” based on the production characteristics of different producing areas. The overall requirements are: timely sowing and transplanting, strengthen the prevention and control of pests and diseases at seedling stage, ensure the quality of whole seedlings. First, the North China beet producing spring production technology 1, paper tube seedling transplanting mode (1) to cultivate strong seedlings. Early nursery, nursery time is generally in late March to early April, seedbed soil selection, and mixed with the fertilizer. Shed promptly after sowing warming, in order to benefit Qi Miao. After emergence to strengthen seedbed temperature and humidity control, depending on the growth of the cotyledon and true leaves, ventilation and cooling, dehumidification. The first pair of true leaves millet size,
