近年来,油菜春播、在长江流域有些地区已实行,产量可喜。但由于对春播改变了原来冬播的生态环境,植株的生态表现和形态特征,还没有足够的了解,耕作栽培措施就往往缺乏针对性。为此,于1980年2月到1981年6月,在江西南昌地区连续二年进行油菜春播生育规律研究,探讨供试材科往春播生态条件下的表现,找出春播生育性状变化与冬播相应性状的 In recent years, rape spring sowing, in some areas of the Yangtze River has been implemented, yield gratifying. However, due to the spring seeding has changed the original winter sowing ecological environment, plant ecological performance and morphological characteristics, there is not enough understanding of the cultivation and cultivation measures are often lack of pertinence. To this end, from February 1980 to June 1981 in Nanchang, Jiangxi Province for two consecutive years of spring rape sowing law to study for the test material to spring sowing ecological conditions, to find out the changes in spring sowing and winter sowing Corresponding traits
