地膜覆盖栽培具有操作简单、省工、成本低、增产幅度大和经济效益高等特点。 1982年全盟共17个试验点,覆膜面积17.93亩,覆膜的平均亩产为9085.8斤,亩产糖量1544.5斤,不覆膜的平均亩产5014.0斤,亩产糖853.9斤,结果覆膜的亩增产量4071.8斤,增糖690.6斤,增产率为81.2％和80.8％,经济收入每亩可增加150元左右。由于经济效益明显,到1983年全盟覆膜甜菜面积已达2903亩,据各旗县共同初步测产,亩产平均达8545斤, Film mulching cultivation has the advantages of simple operation, labor saving, low cost, large yield increase and high economic benefits. 1982 alliance a total of 17 test points, covering an area of ​​17.93 acres, covering an average of 9085.8 kg per mu, mu yield of 1544.5 pounds of sugar, not muffling the average yield of 5014.0 kg, 853.9 kg per mu of sugar, the results Mulch yield 4071.8 kg, 690.6 kg of sugar, the yield was 81.2% and 80.8%, economic income per acre can increase about 150 yuan. Due to the obvious economic benefits, by 1983, the area covered by membrane covered bee reached 2903 mu. According to the common preliminarily measured output of each flag county, the average mu yield reached 8545 kg,
