油菜是越冬作物,头年秋季播种,第二年初夏收获,中间经历一段低温的寒冬,因而自然形成冬前和春后两个生长高峰,冬前是以营养生长为主,春后是以生殖生长为主。其栽培管理要点,在通常情况下,是利用冬前有效积温和光能,主攻冬发,达到冬壮,以旺盛的营养生长来累积较多的营养物质,为春发和高产奠定基础。但是,随着耕作制度的改变、复种指数的提高,油菜面积逐年扩大,明显地出现了油菜高产与前作争地、争季节的矛盾。我县省油菜劳模向多礼通过长期实践,采用培育壮苗移栽的方法,
Rape is a winter crop, the first year of autumn sowing, the second harvest in early summer, the middle of the cold through a period of cold, which naturally form the peak before and after the spring two growth peak, mainly by vegetative growth before winter, spring is reproductive Growth-based. The main points of its cultivation and management, under normal circumstances, is the use of winter effective temperature and light energy, the main winter hair to winter, strong vegetative growth to accumulate more nutrients for spring hair and high yield laid the foundation. However, with the change of farming system and the improvement of multiple cropping index, the area of rapeseed has been expanding year by year, which clearly shows the contradiction between the high output of rapeseed and the previous competition for the season. Our county rapeseed labor model to more ceremony through long-term practice, the use of nurturing strong seedling transplanting method,
