Strawberry prefer warm and cool climate, strawberry root growth temperature 5-30 ℃, 15-22 ℃, stem and leaf growth temperature of 20-30 ℃, buds at -15-10 ℃ frost, bud differentiation period temperature must remain 5-15 ℃, flowering and fruiting period 4-40 ℃. Strawberry summer, the temperature is higher than 30 ℃ and strong sunshine, need to take shade measures.
