The division between vegetative growth and reproductive growth of crops is usually based on flower bud differentiation, which used to be called vegetative growth and later belonged to reproductive growth. Actually, there is no strict boundary between vegetative growth and reproductive growth. For a considerable period of time, vegetative growth and reproductive growth were carried out at the same time, and there was obvious competition for nutrients.
Excessive growth of nutrients is not conducive to the formation of reproductive organs and nutrient accumulation, and the yield is not high. On the other hand, if the vegetative growth is too weak to meet the demand of reproductive growth for nutrients, premature aging will occur and the yield will not keep up.

Important significance
1, prolonging vegetative growth period and inhibiting flowering.
Arrange the cultivation season according to the characteristics of varieties, so that they have a long vegetative growth period to obtain a bumper harvest. For example, in North China and Central China, where the winter temperature is low but cold, autumn sowing of cabbage varieties with strong winterness can avoid immature bolting and obtain higher yield in the next spring.
2. Promote the transformation from vegetative growth to reproductive growth, and blossom and bear fruit early.
For crops with reproductive organs as their products, it is necessary to create an environment suitable for vegetative growth in the early stage of growth, and on this basis, create good conditions for turning to reproductive growth, so that they can normally enter reproductive growth and achieve the goal of early maturity and increase production.
