地膜覆盖栽培自1980年由内蒙古自治区农业厅引进,当年对甜菜进行有色膜小拱棚试验,结果对糖分有明显提高。由于成本高,1981年继之进行地面覆盖栽培预备试验,1982年展开全面布点正式试验和示范。当年对全盟六个旗县共布点十七处,面积17.93亩,示范面积20.57亩,1983年试点六处,面积67.4亩,试验内容有播期、品种、密度等共二十一项,示范和推广面积2835.6亩。1984年设试点八处,面积60.0亩,示范推广面积共为16984.0亩。1985年设试点四处面积53.5亩,推广面积达53640.0亩。从产质量结果看,1982—1984年三年对比试验平均亩产块根达9772.6斤,含糖率17.18％,亩产糖量1678.9斤,对照三年平均亩产块根6002.0斤,含糖率17.26％,亩产糖量1035.9斤,覆膜比对照平均亩增产块根62.8％,亩增糖率为62.1％。现将甜菜地膜覆盖播期和品种试验、示范情况报告如下:
Film mulching cultivation was introduced by Agriculture Department of Inner Mongolia Autonomous Region since 1980, when small-shed experiment of color film on sugar beet was carried out. As a result, the sugar content was obviously improved. Due to the high cost, a groundcover cultivation preliminary test was carried out in 1981 and a formal test and demonstration was carried out in 1982. In the same year, there were 17 points and 17.93 mu of demonstration sites covering an area of 17.93 mu and six pilot counties in 1983, covering an area of 67.4 mu. There were 21 sowing dates, varieties and densities in total. The demonstration And to promote the area of 2835.6 acres. 1984 set eight pilot, an area of 60.0 acres, demonstration and promotion of a total area of 16984.0 acres. In 1985 set up a pilot area of 53.5 acres around the area of 53,640.0 acres of promotion. From the quality of the results, 1982-1984 three years comparative test average yield of 9772.6 kg per mu, sugar content of 17.18%, yield of 1,678.9 kg of sugar per mu, control three years average yield of 6002.0 kg per mu root, sugar content of 17.26% , Mu yield of 1035.9 pounds of sugar, covering an average of 62.8% increase over the control of mu root tuber, mu by sugar rate was 62.1%. Now beet mulching sowing date and species trials, the demonstration of the situation reported as follows:
