我国的甜菜单产长期在1吨左右徘徊,低于世界平均水平。从1983年起,农牧渔业部全国农业技术推广总站把“甜菜亩产两吨综合栽培技术”作为重点农业技术推广项目,在黑龙江、吉林、内蒙古三省、区的4个县市组织示范、推广。1984、1985年扩大到6个县市共有59万亩,占这些地区种植面积的30％,达到亩产两吨。因地制宜地将亩产两吨的栽培技术进行大面积推广,将对提高我国甜菜生产水平起重要作用。其要点如下:
China’s sugar beet production lingered for a long time in about 1 ton, below the world average. Since 1983, the National Agricultural Technology Extension Station of the Ministry of Agriculture, Animal and Animal Husbandry has organized and promoted “two-ton comprehensive cultivation techniques for sugar beet mu production” as a key agricultural technology promotion project in four counties and cities in Heilongjiang, Jilin and Inner Mongolia provinces and regions . In 1984 and 1985, the area expanded to 6 counties with a total area of 59 million mu, accounting for 30% of the acreage planted in these areas, reaching a yield of 2 tons per mu. The large-scale popularization of cultivation techniques of two tons per mu according to the local conditions will play an important role in raising the level of sugar beet production in our country. The main points are as follows:
