寒地(黑龙江)萝卜生产中,存在着较严重的当年抽苔问题,影响萝卜的品质和产量,有时全部毁产。因此,提出解决“黑龙江省萝卜当年抽苔问题”的这一项科学研究题目。 根据过去前川十郎、岩间诚造、艾捷里斯坦等人的研究资料,他们都认为种子发芽后,在幼苗时期,遭到1—3℃的低温以后再遇着长日照和比较高的温度时,便促进了它迅速的抽苔,但是这种现象,是因品种不同而有显著的差别。否认了是由于种子
Cold (Heilongjiang) radish production, there is a more serious problem that year bolting, radish quality and yield, and sometimes all ruined. Therefore, it is proposed to solve the problem of bolting in Heilongjiang Radish that year. This is a scientific research topic. According to the research data of former Kanagawajuro, Iwao Seijo, and Aitelistan, they all think that after the seed germinates, it encounters long-day sunshine and relatively high temperature , It promotes its rapid bolting, but this phenomenon is due to different species have significant differences.
