甘兰型油菜原产欧洲,是近百年来才应用于农业生产的油菜新类型。解放以后开始在我国试种推广。由于抗病、耐肥、高产、稳产,较其它油菜类型有显著优点,推广至今,不到二十年时间,巳成为我国栽培面积最大的油菜类型。种植面积占全国油菜总面积的一半以上。正如伟大领袖毛主席所说:“有了优良品种,即不增加劳动力、肥料,也可获得较多的收成。”解放以后,甘兰型油菜在我国生产上的应用,对于增加油料产量起了很大作用。甘兰型油菜,从生物学上说,是一个异源多倍体作物,具有特殊的生长优势。因此,在近代农业发展中,为了提高油菜产量,许多国家都经历了换种甘兰型油菜的过程。目前世界上
Brandy-type rape native Europe, is a new type of rapeseed applied to agricultural production in the past century. After liberation began to promote cultivation in our country.
