我市油菜常年种植面积85万亩左右,占油料作物种植总面积的83.6%,总产10万吨以上。主要栽培品种有农林43、中油821、秦油2号等。这些品种推广多年后,表现出产量不稳定,增产潜力有限,品质下降,出油率低等。1988年,我们引进华中农业大学付廷栋教授选育的低芥酸油菜三系杂交种华杂2号进行试验示范。几年来,累计示范推广2万多亩,平均单产150～160公斤,比大面积中油821增产13.6～16.2%。在
The annual planting area of rape in our city is about 850,000 mu, accounting for 83.6% of the total area planted with oil crops and the total output is over 100,000 tons. Main cultivars include agriculture and forestry 43, CNPC 821, and Qinyou 2. After many years of promotion of these varieties, they have shown unstable output, limited production potential, poor quality and low oil yield. In 1988, we introduced Hua-Zhong No.2, a low-erucic acid rapeseed hybrid, bred by Prof. Ting-Dong Hu from Huazhong Agricultural University. Over the past few years, a total of 20000 acres of demonstration and extension, the average yield of 150 to 160 kg, 821 larger than the large area of 13.6 to 16.2% increase. in
