Abstract: In order to reduce the phenomenon of early bolting in the production of root chicory,Belgian root chicory was used as material to study the effect of different transplanting time on early bolting of chicory.The results showed that the suitable time for seedling raising and transplanting was 4 leaves and 1 heart stage,and the fresh weight of roots was 114.70 g and bolting rate was 21.11%.At this time,transplanting had little effect on the growth and bolting rate of fleshy roots.In production,it is suggested that chicory should be transplanted at 4 leaves and 1 heart stage to inhibit bolting.
