The purpose of facility cultivation of strawberries is for early fruit and early market. The key measures are to promote flower bud differentiation and promote flowering. There are several ways to promote flowering:
Temperature and humidity management The temperature in the shed is around 30°C during the day and 10°C at night. Try to increase the ground temperature and promote root activity. The air humidity is 50% to 60%, and low humidity is not only good for flowering and pollination, but also good for preventing disease.
Supplementary lighting: Hang a 20-watt energy-saving lamp 1 meter above the plant, one light every 4 meters. Turn on the lights after sunset and turn off the lights at 10 pm.
Hormone supplementation. If the plant has dwarf dormancy due to low temperature, use gibberellin to break dormancy, spray 10ppm gibberellin once before budding, and then spray again after a week.
Arrange the plants. Arrange the plants to concentrate nutrients and promote flowering. Before the top inflorescence is extracted, only one terminal bud is left. After the top inflorescence is extracted, two axillary buds are selected and the redundant axillary buds are removed at any time. Plants with three buds generally have 3 to 5 inflorescences and retain about 15 leaves.
