Propagation mode of strawberry: Seed propagation is mostly used for long-distance introduction or cultivation of strawberry seedlings to select new varieties, and can also be used for dual-purpose cultivation in courtyard greening. When fruits are harvested in May and June, well-developed and fully mature fruits are selected for seed collection.

Peel off the peel, put it in water, wash off the slurry, and take it out to dry; Or directly air-dry the peeled skin, and then crush it to separate the skin from the seeds. Seeding and seedling raising are mostly carried out in the spring of the following year, but they can also be carried out in July-August of the year of seed collection.

Before sowing, prepare a wide-mouth pottery jar, fill it with fine nutrient soil, flatten it, soak the seeds 8- 12 hours in advance, spread it on the soil surface after expansion, and then cover it with fine sand with a sieve about 0.2 cm thick.

In order to keep enough moisture in the soil and keep it loose, which is beneficial for the seeds to take root and sprout, the sowed clay earthen basin can be put into a shallow pool, taken out after the water slowly penetrates into the soil in the basin, covered with plastic film, and the seedlings can emerge in about 10 days.

Growth habit

Strawberries like warm and cool climate. The growth temperature of strawberry root system is 5-30℃, the optimum temperature is 15-22℃, the optimum temperature of stem and leaf growth is 20-30℃, the freezing temperature of flower bud is-10℃, and the temperature of flower bud differentiation must be kept at 5-15. When the temperature is higher than 30℃ and the sunshine is strong, shading measures should be taken.

Strawberry is a light-loving plant, but it has strong shade tolerance. Under the light intensity, the plant is short and strong, the fruit is small, the color is dark and the quality is good. Medium light, large fruit, light color, low sugar content and long harvest period; Weak light is bad for strawberry growth.

Strawberry has shallow root distribution, large transpiration and strict requirements for water, but its growth stages are different. Strawberries have slightly different water requirements. Strawberries should be planted in fertile, loose, neutral or slightly acidic loam. Too sticky soil is not suitable for cultivation. Strawberries can also be planted on sandy soil with more fertilizer and regular irrigation.
