1981年以来,我县油菜生产发展较快,种植面积大幅度增加。以往,全县油菜面积基本稳定在11万亩左右,占夏熟面积的35％,1981年秋种已扩大到15.86万亩,最近二年(1985～1986)都突破了20万亩。1986年达到26.15万亩,占夏熟面积的64％.不但油菜的种植面积增加,而且连年取得丰收,1981～1986的6年中,年年亩产超过270斤,平均年亩产量293.4斤,比前6年(1975～1980)平均年亩产242.5斤,增产50.9斤,平均每年递增8.5斤,递增率为3.5％,由于面积和单产同时上升,总产增加就更为明显,最近二年(1985～1986)全县油菜籽总产超过6500万斤,1986年总产超历史,达到
Since 1981, rapeseed production in our county has been developing rapidly with a sharp increase in planting area. In the past, the area rapeseed area basically stable at 11 million mu, accounting for 35% of summer ripening area, the autumn of 1981 species has been expanded to 158,600 mu, the last two years (1985 ~ 1986) have exceeded 200,000 mu. 1986 reached 26.15 hectares, accounting for 64% of summer area.Not only the rapeseed area increased, but also achieved bumper year after year, from 1981 to 1986, 6 years, every year more than 270 pounds per mu, the average annual yield of 293.4 kg per mu, Compared with the previous 6 years (1975-1980), the average annual output per mu yield was 242.5 kg, an increase of 50.9 kg and an average annual increase of 8.5 kg, an increasing rate of 3.5%. As the area and yield increased at the same time, the increase in total output was even more pronounced. In the recent two years (1985 ~ 1986) rapeseed production in the county more than 65 million kg, total production in 1986 ultra-history, achieved
