Strawberry flower bud differentiation and fertilization management are very important to improve yield and quality.Commonly used chemicals include Gibberellic Acid (GA3), Brassinolide (BR) and Difenoconazole.

Gibberellic Acid GA3,strawberries can promote the formation of flower buds under low temperature and short daylight conditions.However, when strawberries are cultivated under protective facilities, or because the temperature during planting is too high and cannot meet the normal low temperature requirements, the plant growth will be dwarfed and the flower buds will differentiate,Reduced flowering and fruiting.

Cytokinin
Spraying with 10~20mg/L liquid after the flowers fall can increase the leaf color, thicken the leaves, increase the fruit setting rate by 22.4%, increase the single fruit weight by 13.2%, reduce the weight of the peach stone, increase the rate of large fruit, mature 4 days earlier, and improve Coloring, improving quality. The total sugar content increase by 0.6, the soluble solids increase by 1%, and the fruit acid decrease.

Root growing
Naphthalene acetic acid (NAA) ，
According to the test, using 500mg/L Naphthalene acetic acid (NAA) powder, dipping the apple dwarfing stock M4 and M2, the root rate was 50% and 25% respectively; After soaking in 50mg/L Naphthalene acetic acid (NAA) solution for 24 hours and inserting the rod, the rooting rate was 35.7%.
