Litchi trees like high temperature and humidity, light and sunshine. The genetic requirement is that the temperature of flower bud differentiation is relatively low, but the lowest temperature is -2 ~-4℃. Sunny, warm, dry and hot weather, low humidity, continuous rainfall, dry and hot weather or strong north wind are not conducive to flowering and pollination. Unfavorable weather disasters in the flower and fruit period may lead to falling flowers and fruits, and even cause harvest loss.

There are four types of litchi flowers: female flowers, male flowers, bisexual flowers and deformed flowers. There are many hermaphroditic flowers, but few hermaphroditic flowers, and abnormal flowers are not pollinated well.
