十字花科蔬菜在高寒地区栽培时容易发生早期抽苔是一个比较普遍的现象,尤其结球白菜早期抽苔的现象更为严重,由于早期抽苔开花而不能形成叶球或结球不良,不仅产量受到严重影响,而且产品质量也严重下降。因此,研究高寒地区气候条件对结球白菜生长发育的影响、发生早期抽苔的原因、以及防止早期抽苔的技术措施等问题,是值得十分注意的问题。现就我所已往的试验资料,并参阅国内有关报导作一初步分析。 It is a common phenomenon that cruciferous vegetables are prone to early bolting when cultivated in the alpine region. In particular, bolting of cabbage is more serious in the early stage. Early bolting and flowering can not form leaf or bad knot, not only Production is severely affected, and product quality is also severely degraded. Therefore, the study of climatic conditions in the cold region on the growth and development of cabbage, the reasons for the occurrence of early bolting, as well as to prevent the technical measures of early bolting and other issues, is worthy of attention. Now I have to the test data, and refer to the domestic reports for a preliminary analysis.
