Morphological characteristics and appearance of strawberries Strawberries are perennial herbs. Height 10-40 cm, stem lower than leaves or nearly equal length, densely yellow pilose. The leaves are trifoliate, the leaflets are short-stalked, the texture is thick, obovate or rhombic, the upper part is dark green, almost hairless, the lower part is pale white-green, sparsely hairy, densely along the veins, and the petiole is densely yellow. Suitable growing environment and conditions for strawberries Strawberries are produced in South America, mainly in Asia, Europe and America. Strawberries are distributed in Hebei, Shandong and many provinces and cities in southern China. The national strawberry area is 6.5438+0.5 million mu, and the producing areas are mainly distributed in Sichuan, Hebei, Anhui, Liaoning, Dushan and other places. In what environment do strawberries grow? Strawberries are light-loving plants, but they have 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. Strawberry has shallow root distribution, large transpiration and strict requirements for water. However, at different growth stages, strawberry has slightly different requirements for water.

In early spring and flowering period, the amount of coral and strawberry should be less than 70% of the maximum soil water capacity. The demand for fruit growth and ripening is the highest, reaching more than 80%. After harvesting, the soil water content of stolons and adventitious roots should be not less than 70%.

Autumn is the period of plant nutrient accumulation and flower bud formation, and the soil moisture should not be lower than 60%. 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. Generally speaking, the suitable growth temperature for strawberries is a warm and cool climate. The growth temperature of strawberry roots is 5-30℃, the suitable temperature is 15-22℃, the suitable temperature for stem and leaf growth is 20-30℃, the bud is frozen at-15- 10℃, and the temperature during flower bud differentiation must be maintained at 5-65438+. Strawberry in summer, when the temperature is higher than 30℃ and the sunshine is strong, shading measures should be taken.
