The process of strawberry formation is as follows:

1. Germination stage. When the ground temperature is generally stable at 2~5°C in spring, the strawberry root system begins to grow, and the root system will grow 7 to 10 days earlier than the above-ground part. You must know that the strawberry root system growth at this time is mainly the continued extension of the roots that grew last autumn, and will continue to grow as time goes by. As the ground temperature rises, new roots gradually sprout.

2. Budding period. Flower buds will appear about a month after the strawberry germinates. When the new stem of the strawberry grows 3 leaves, but the fourth leaf has not grown, the inflorescence will be exposed in the stipule of the fourth leaf, and then the peduncle will elongate. Expose the entire inflorescence.

3. Flowering and fruiting period. It takes about 15 days from the flower buds to the first flower to open, and about 30 days from flowering to fruit maturity. The length of the flowering period varies depending on the strawberry variety and planting environment conditions, and generally lasts about 20 days.

4. The vigorous growth period. After the first batch of strawberries are harvested, a large number of stolons appear in the axillary buds, and the branching of new stems accelerates their growth. Adventitious roots appear at the base of the new stems, forming a new root system. The large number of stolons and new stems form new strawberry plants, which enter vigorous growth. Expect.

5. Flower bud differentiation stage. After the strawberry has gone through a vigorous growth period, it begins the flower bud differentiation stage under the conditions of low external temperature (average daily low temperature 15~20℃) and short daylight (10~12 hours). It also starts from the differentiation of strawberry flower buds, marking the transformation of the plant from vegetative growth. Shift to reproductive growth.

6. Dormant period. Strawberries in the open air will also go through a dormant period. After the flower buds are formed, due to the gradual decrease in temperature and shortened sunshine, the strawberries will enter the dormant period. The main symptoms are short petioles, few leaves and small leaf area. The original upright and oblique leaves develop into It grows parallel to the ground and grows prostrate. The whole plant is dwarfed and has a rosette shape. It grows extremely slowly.

The development history of strawberry:

We humans have eaten strawberries for a long time. Archaeological evidence shows that as early as the Stone Age, humans have begun to collect and eat strawberries. Strawberries at that time were completely different from strawberries today. The species of Fragaria eaten at that time were wild strawberries, which were distributed in the northern hemisphere. The fruits were small and lacked flavor. The first people to grow wild strawberries were the ancient Persians.

Subsequently, Europeans also introduced this plant from the forest to farmland, but it was not always used as a fruit. Starting from ancient Roman times, Europeans regarded wild strawberries as a medicinal plant, and Fragaria genus The scientific name Fragaria is fragrant, which is where it comes from. In short, the status of strawberry as a fruit during this period was quite embarrassing.
