Characteristics of flowering and pollination of jujube trees

Jujube is a small and typical insect-pollinated flower, and most varieties can bear fruit by themselves. The jujube flower blossoms first from the bottom to the top, and the central flower blossoms first and the lateral flower then blossoms in the same inflorescence. The single flower blooming time of jujube is completed in one day, the pollination time can be as long as 2 days, the optimum temperature for pollination is 24 to 26 degrees, and the air temperature is 80%. High temperature (higher than 38 degrees), low temperature (lower than 20 degrees) and too dry air are not conducive to pollination and fertilization.
