为探讨内蒙赤峰市北部甜菜产区的防风、保墒、增产、增糖栽培新措施，进行了４种栽培方式试验：纸筒育苗覆膜后移栽、纸筒育苗移栽、直播覆膜栽培、直播（对照）。结果表明，纸筒育苗覆膜移栽甜菜产量、含糖率、产糖量比直播分别提高１５３．５％、０．４度、１６２．４％，每亩农业和工业纯收入居４种栽培方式之首。纸筒育苗移栽甜菜产量、含糖率、产糖量比直播务别提高７５．６％、０．５度、８２．８％，每亩农业和工业纯收入在４种栽培方式中居第二位。直播覆膜栽培甜菜根产量、产糖量比直播分别提高５０．０％、４８．２％，含糖率下降了０．４度，每亩农业和工业纯收入在４种栽培方式中居第三位。
In order to explore the new measures of windbreak, soil moisture conservation, increase yield and sugar increase in the northern sugar beet producing area in Chifeng, Inner Mongolia, four cultivation methods were tested: transplanting of paper tube seedling after filming, transplanting of paper tube seedling, direct film mulching cultivation, Live (control). The results showed that the yield, sugar content and yield of sugarbeet transplanted by paper tube seedling increased 153.5%, 0.4% and 162.4% respectively than that of direct seeding, and the cultivation of four kinds of agricultural and industrial net income per acre First of all. The yield and sugar content of sugar beet transplanted in paper tube seedling increased by 75.6%, 0.5% and 82.8% respectively compared with those of live broadcast seedlings. The net agricultural and industrial income per acre ranked the second among the four cultivation methods Bit. The yield and the sugar yield of direct film mulching cultivation were increased by 50.0% and 48.2%, respectively, and the sugar content decreased by 0.4 degrees. The agricultural and industrial net income per acre ranked the third among the four cultivation methods Bit.
