The growth cycle of strawberries can be divided into the following stages:
(1) budding stage
When the ground temperature is stable at 2℃-5℃ in spring, the roots begin to grow. The root system grows 7- 10 days earlier than the aboveground part. At this time, the root growth is mainly due to the continuous elongation of the roots that grew last autumn, and new roots appear with the increase of local temperature.
⑵ Buding period
The shoots grew for about a month and appeared buds. When the new stem grows three leaves, but the fourth leaf does not grow, the inflorescence is exposed to the leaf sheath of the fourth leaf, and then the peduncle is extended to expose the whole inflorescence.
(3) fruiting period
It takes about 15 days from the bud to the first flower. It takes about 30 days from flowering to fruit ripening. The length of flowering period varies with varieties and environmental conditions. The general duration will be around 20 days.
(4) vigorous growth period
After the berries are harvested, the plants enter a vigorous growth period. First, a large number of stolons occur in axillary buds, and the branches of new stems grow faster, and adventitious roots occur at the base of new stems, forming new roots. A large number of stolons and new stems will form new seedlings.
5] flower bud differentiation stage
After the vigorous growth period, strawberry flower bud differentiation began under the conditions of external low temperature (daily average low temperature 15-20℃) and short sunshine (10- 12 hours). The beginning of flower bud differentiation marks the transition from vegetative growth to reproductive growth.
[6] dormant period
After the formation of flower buds, the temperature gradually decreased, the sunshine became shorter, and strawberries entered the dormant period, which was characterized by short petioles, few leaves and small leaf area. The incidence angle of leaves changed from vertical inclination to creeping growth parallel to the ground, and the whole plant was dwarfed like a rosette, which grew very slowly.
