Strawberry seedlings should be strengthened in winter, especially in the north. Pull rods can be added to both sides of the greenhouse, and columns can also be added to the greenhouse. When it snows, clear the snow in time to prevent the greenhouse from collapsing. Keeping warm is also necessary. When the temperature is lower than 0℃, it should be covered with a film, and when it is lower than -5℃, it should be covered with another film. Uncover the film during the day to increase the temperature in the greenhouse and promote photosynthesis. The drainage ditch in the greenhouse should be cleaned in time to prevent water accumulation.

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. Strawberry in summer, 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. In early spring and flowering period, strawberry needs a lint percentage lower than 70% of the maximum soil water capacity. The demand for fruit growth and ripening is the highest, reaching more than 80%. After harvesting, stolons and new adventitious roots should be removed, and the soil moisture content should not be lower than 70%. Autumn is the period when plants accumulate nutrients and form flower buds, and the soil water content should not be lower than 60%. Strawberries are not resistant to waterlogging, which requires good soil permeability, and pay attention to drainage in rainy season.
