近年来我国甜菜生产有较大发展,种植面积已达五百多万亩,但机械化程度很低,主要用人畜力作业。国外栽培一亩甜菜,先进水平仅用0.27～0.33工,一般为0.5～0.7工,而我们需要10～11工,约为玉米、大豆的2.5倍。甜菜集中产区常与大田作物争工争时争畜,出现顾此失彼,管理不善等现象,迫切需要实现机械化。吉林省甜菜播种主要采用人工刨掩种。每亩用2.7～3.3工,约占全部栽培工时四分之一;用种量大,达2.7斤/亩,大多数
In recent years, there has been a great development in the production of sugar beet in China. The cultivated area has reached over 5 million mu. However, the degree of mechanization is very low, mainly using manpower and force operations. Cultivation of foreign acres of beets, the advanced level only 0.27 ~ 0.33 workers, usually 0.5 ~ 0.7 workers, and we need 10 to 11 workers, about 2.5 times the corn, soybeans. Beet concentrated areas often compete with the field crops fight for livestock, appear to defeat one another, poor management and other phenomena, the urgent need to achieve mechanization. Jilin Province beet seeding planted mainly by artificial planing. 2.7 ~ 3.3 workers per acre, accounting for about one-fourth of the total training time; with a large amount, up to 2.7 kg / mu, most
