Growth characteristics of rapeseed bud bolts

The bud bolting stage of rapeseed is the growth stage from the budding of rape to the first flowering, and the bud bolting stage of rape is the period of vegetative growth and reproductive growth. The most prominent performance in this stage is the substantial increase in leaf area, and the leaf area index reaches the maximum in the whole life at the early flowering stage. The bud bolting stage of rapeseed is the key period in which rape grows steadily in spring, reaching strong roots, strong culms and many branches, which lays the foundation for more horns, more grains and grain weight. It is also the period when rape absorbs the most nitrogen and potassium nutrients.
