Beet is one of the main cashmere crops in Emin County. Due to the small beet seeds and the emergence of seedlings, in addition, there is little snowfall in autumn and winter in Emin County. As the spring monsoon is strong and the soil is vulnerable to moisture, it is very difficult to maintain the seedlings. Through the application of sugar beet mulching and drip irrigating technology, it can achieve the purpose of preserving soil moisture, raising ground temperature, sowing early, raising germination rate, increasing seedling growth and eliminating weeds. First, the cultivation requirements 1 selected beet root developed, requiring large amount of water needed to select the soil is rich, fertile soil, water and fertilizer ability, organic matter content of more than 1.5% of loam, sandy loam plots is appropriate. Beet stubble to wheat, rapeseed,
