本地区是我省的向日葵主产区。自1980年以来,白城地区已被列为国家重点向日葵生产基地。我区种植面积逐年扩大,由1979年的110万亩发展到1985年的320万亩,占全国向日葵播种面积的六分之一,占全省70％;产量占全国总产近五分之一,占全省80％以上。然而由于价格政策和栽培措施等方面的原因,导致近年来向日葵生产呈滑坡趋势。为尽快恢复和发展我区的向日葵生产,解决多年来向日葵栽培上存在的技术难题,我们借鉴白城地区农业科学
The area is the main producing area of sunflower in our province. Since 1980, Baicheng area has been listed as a national key sunflower production base. The area under cultivation in our region has been expanding year by year from 1.1 million mu in 1979 to 320 million mu in 1985, accounting for one sixth of the national sunflower sown area and accounting for 70% of the province’s output. Its output accounts for nearly one fifth of the country’s total output , Accounting for more than 80% of the province. However, due to price policy and cultivation measures and other reasons, leading to the sunflower production in recent years showed a trend of landslide. In order to restore and develop sunflower production in our region as soon as possible and to solve the technical problems of sunflower cultivation over the years, we draw lessons from Baicheng District Agricultural Science
