近年来,我省运城地区甘蓝露地越冬制种基地不断发展扩大,并有丰产经验报道。但也存在产量不稳问题,不同年份差异很大。要获得稳产丰产,从栽培管理方面来讲,培养大小适宜、健壮、抗逆性强的种株,安全越冬,是重要的基础;加强春夏季各个时期的管理则是又一重要方面。 In recent years, Yuncheng area of ​​our province open field winter cabbage seed production base to continue the development and expansion, and rich experience in the report. However, there are also problems with production instability, which vary greatly from year to year.

Strengthening management in all phases of spring and summer is another important aspect.
