基本情况 我区甜菜地膜覆盖栽培技术,自1980年试验以来,发展较快。赤峰试验结果,覆膜比未覆膜的亩增产1400斤,增长32.3％,含糖率亦有所提高。1982年巴盟在六个旗县对甜菜进行膜栽试验,面积17.93亩,平均单产9085.8斤,比对照亩增产4071.8斤。1982年赤峰五三公社18亩甜菜试验田,覆膜的亩产5517.4斤,比对照增产33.5％。在各点小面积试验取得成功的基础上,1983年发展到七盟二市扩大示范,面积达4000多亩,除少数未按栽培技术要求操作者外,都显示了增产、增收效益,并涌现了一批高产典型。如巴盟地区1983年甜菜地膜覆盖面积达2903亩,平均亩产达8500斤,含糖率比对照高0.5—0.9％,其中有323.5亩试验田平均亩产9444.7斤,比对照5625斤增产3464斤;临河县乌兰乡立新六社典型户乔玉玺覆膜甜菜9.1亩,平均亩产10249.6斤。赤峰五三公社覆膜甜菜520亩,在大旱之年平均亩产5071斤,比对照亩增产41.5％;呼市白庙子公社39亩示范田覆膜甜菜,平均亩产8721.6斤,比对照增产36.7％,含糖增0.4％。
Basic situation My sugar beet mulching cultivation techniques, since the 1980 test, the rapid development. The result of Chifeng test showed that the mu yield of mucilage film increased by 1400 pounds, an increase of 32.3% and the sugar content rate also increased. In 1982, Bamei film-tested sugarbeet in six flag counties, with an area of 17.93 mu and an average yield of 9085.8 kg, an increase of 4071.8 kg compared with the control. 1982 Chifeng 53 communes 18 acres of sugar beet trial field, covering 5517.4 kg per mu, 33.5% more yield than the control. On the basis of the success of small-area experiments at various points, the seven cities and two cities expanded their scale to more than 4,000 mu in 1983 with the exception of a few who did not require operators according to cultivation techniques, and all of them showed an increase in yield and increased income and emerged A number of high-yield typical. For example, in the Bameng area, the covered area of beet mulch covers an area of 2903 mu in 1983 with an average yield of 8,500 kg per mu and a sugar content of 0.5-0.9% higher than that of the control. An average of 9444.7 kg mu of 323.5 mu mu of paddy fields was produced, an increase of 3464 kg ; Linhe County Wulan Township Liuxinyu typical households Qiu Yuxi covered beet 9.1 acres, the average yield 10249.6 kg. Chifeng 53 commune covered 520 acres of sugar beet, in the dry year the average yield per annum 5071 pounds, 41.5% more than the control acres; 39 acres of Hohhot Baimiaozi commune demonstration mulch sugar beet, the average yield 8721.6 kg, compared with the control 36.7% increase in production, sugar increased by 0.4%.
