地膜覆盖甜莱栽培是叨年代初引进的先进技术，经过十几年的试验、示范推广结果表明，可有效克服新疆早春低温、干旱等不良自然因素，提高保苗率，促进幼苗早发，延长甜菜生育期，大幅度提高块根产量，是发展甜菜生产，提高单产，增加经济效益的有效措施。据统计，目前新疆地膜 Film mulch cultivation is the advanced technology introduced in the early 1980s. After more than ten years of experiments, the result of demonstration and popularization shows that it can effectively overcome the natural factors such as low temperature and drought in Xinjiang in early spring, improve the seedling protection rate, promote early seedling emergence, Growth period, a substantial increase in tuber yield, is the development of sugar beet production, increase yields, increase economic efficiency of the effective measures. According to statistics, the current film in Xinjiang
