北方冬油菜科研、生产协作总结会于1983年4月11—15日在江苏淮阴市召开。会议认真总结交流了油菜科研、生产协作经验,回顾了1980年北方八省冬油菜生产技术考察以来,北方冬油菜在防冻保苗、高产栽培关键技术开展协作研究方面,取得了良好的效果。这个地区的油菜面积从1980年实收600万亩扩大到1000万亩左右,单产从102斤提高到158斤,提高80％,总产增加6.04亿斤。1981—1982年度油菜防冻保苗综合技术在河南省、苏北、皖北等地区推广应用,油菜保收率由28.8％提高到90.7％。
North winter rapeseed scientific research, production collaboration concluded in April 1983 April 11-15 in Huaiyin City, Jiangsu Province. The meeting earnestly summed up the exchange of rapeseed scientific research and production collaboration experience, reviewing the 1980 northern provinces rapeseed production technology inspection since the northern winter rape in frost-seedlings, high-yielding cultivation of key technologies to carry out collaborative research and achieved good results. Rapeseed area in this area was expanded from 600 million mu in 1980 to about 10 million mu, with the yield increasing from 102 to 158 kg, an increase of 80% and the total output increased by 604 million kg. The comprehensive technology of anti-freezing and seedling protection of rapeseed in 1981-1982 was applied and popularized in Henan, North Jiangsu, North Anhui and other regions. The coverage rate of rapeseed increased from 28.8% to 90.7%.
