油菜对温度的反应很敏感,诸如苗期生长、花芽分化、现蕾、开花、成熟,均对温度有较严的要求。温度是决定油菜分布的一个重要生态因素,也是决定栽培措施的有力依据。过去对油菜积温的研究所见不多,特别是对杂交油菜的积温尚无报 Rape response to temperature is very sensitive, such as seedling growth, flower bud differentiation, budding, flowering, mature, are more stringent temperature requirements. Temperature is an important ecological factor that determines the distribution of rape and is also a strong basis for determining cultivation measures. In the past, there was not much research on the accumulated temperature of rapeseed, especially for the accumulated temperature of rapeseed
