1. The flowering period of jujube trees is generally from May to June. At this time, it is the period of rapid growth of jujube new shoots and new roots. This has the problem of nutrient growth and reproductive growth on nutrients. Therefore, if nutrients are supplied to If the amount of flowers is insufficient, the bracts are incompletely unfolded, pollination and fertilization are poor, and within 1 week after flowering, all of these flowers fall off.
2. During the flowering period of jujube trees, if there is a long-term dry weather, there will be a phenomenon that the pollen tube does not germinate and the pollen does not spread, so that the amount of flowers that complete pollination is reduced, and the flowers without pollination fall off.
3. When the jujube tree blooms, if it rains for a long time, the pollen will flow poorly and the number of insects will decrease. Therefore, the pollination will cause a large number of unfinished flowers to fall off.
