Gladiolus can be divided into two varieties: spring flower and summer flower. Different varieties have different growth periods. The early varieties bloom in 50-601 days, medium maturity in 65-80 days and late maturity in 80-120 days.
Gladiolus like long sunshine, in the sunny environment (more than 14 hours of light), the temperature is suitable, flowering earlier. The flowering time of Gladiolus can be effectively controlled by adjusting light time and temperature.
Gladiolus has a dormancy period of 2-3 months every year. The environment is suitable in time and it will not grow. In order to make it bloom earlier, it is necessary to break its dormancy period. The seed balls were stored at 0 ~ 4 ℃ for 30 ~ 50 days, or soaked in 39 ℃ water for 2 weeks, and the dormancy was relieved. In such a way, as long as the seed ball is allowed to sleep in advance, the seed ball will blossom earlier than the ordinary seed ball after planting.
It's simple. It's necessary to delay flowering, let the seed ball sleep for a while, and put it in a dry and low-temperature environment. Before the flowering time is planned, the temperature rises and the humidity increases, breaking the dormancy. The rest is the same as the method of promoting flowers. Normal maintenance is OK.
However, it should be noted that repeated tossing of the seed ball will accelerate the degradation and pay attention to seed retention. In addition, promoting and prolonging flowers can be used alternately to ensure the robust growth of seed balls.
