东北垄作区(包括内蒙古东部地区)是我国的甜菜主产区,种植面积占全国的70%以上,产量一直徘徊在每亩1吨左右,增产潜力很太。我们经过试验认为:甜菜大垄栽培具有改善生态环境,提高种植密度,协调群体结构,增强光合作用能力等优点,在保持该地区垄作特点的条件下,对提高甜菜单产,增加产糖量具有良好的作用。所谓大垄是指将传统垄距为66～70厘米的小垄改为垄距为132～140厘米或100～105厘米的大垄。在垄
The northeast ridge area (including the eastern part of Inner Mongolia) is the main beet producing area in China. Its planting area accounts for more than 70% of the national total. The output has been hovering around 1 ton per mu and the production potential is very high. We have experimented that the cultivation of beet big ridge has the advantages of improving ecological environment, increasing planting density, coordinating population structure and enhancing photosynthetic capacity. Under the condition of maintaining the characteristics of ridge cultivation in this area, it has a good effect on raising yield of sugar beet and increasing sugar yield Role. The so-called big ridge refers to the traditional ridge distance of 66 to 70 cm ridge changed to Ridge ridge distance of 132 to 140 cm or 100 to 105 cm wide ridge. In the ridge
