Known as the "Queen of Fruits", it is rich in vitamin C, vitamin A, vitamin E, vitamin PP, vitamin B1, vitamin B2, carotene, tannic acid, aspartic acid, copper, strawberry amine, pectin, and fiber.

Especially the vitamin C content, which is 7-10 times higher than that of apples and grapes. The content of malic acid, citric acid, vitamin B1, vitamin B2, carotene, calcium, phosphorus, and iron is also 3 to 4 times higher than that of apples, pears, and grapes.
2. Growth habits of strawberries
Strawberries like warm and cool climates. The growth temperature of strawberry roots is 5-30℃, the optimum temperature is 15-22℃, and the optimum temperature for stem and leaf growth is 20-20℃. 30℃, buds will be damaged by freezing at -15-10℃, the temperature must be maintained at 5-15℃ during the flower bud differentiation period, and 4-40℃ during the flowering and fruiting period. When strawberries are over summer, when the temperature is higher than 30°C and the sunshine is strong, shading measures must be taken.
Strawberries are light-loving plants, but they also have strong shade tolerance. When the light is strong, the plants will be short and sturdy, the fruits will be small, dark in color and of good quality. Medium light, large fruit, light color, low sugar content, long harvest period; too weak light is detrimental to strawberry growth.
Strawberry has shallow root system distribution, large transpiration volume, and strict water requirements, but it has different growth stages. Strawberries have slightly different moisture requirements. In early spring and during the flowering period, strawberries require a minimum of 70% lint content below the soil's maximum water holding capacity. The fruit needs the most during the growth and maturity period, reaching more than 80%. After harvesting, the soil moisture content must not be less than 70% when extracting stolons and developing new adventitious roots. Autumn is the period when plants accumulate nutrients and flower buds form, and the soil moisture must not be less than 60%. , Strawberries are not tolerant to waterlogging, and require good soil permeability, and pay attention to field drainage during the rainy season.
Strawberries should grow in fertile, loose neutral or slightly acidic loam. Too heavy soil is not suitable for cultivation. Apply more manure on sandy soil and irrigate frequently. Strawberries can also be grown in sandy soil.
