Chrysanthemum flowering control

Chrysanthemum is a short-day plant. Flower bud differentiation occurs only under short-day conditions, so the flowering period can be controlled by controlling the length of daylight. For this reason, flowers must bloom under long-day conditions and short days should be handled. When the plants are vigorously grown in advance and the shoots grow to 9-12 cm, they are only given 9-10 hours of light each day. The rest of the time can be covered with black cloth or black plastic film (appropriate for morning and evening, overheated at noon). . The effective induction of short days is at the top, so the upper part must be completely dark and the base is lax. After about 30-40 days of treatment, chrysanthemums can form buds, and later they can go to cover and strengthen fertilizer and water management. In order to delay flowering, late flowering varieties can also be selected. The method of prolonging sunshine can prevent flower bud formation and delay flowering. China Agricultural Network Editor
