How does the fruit of the tree grow?

How do jujube trees protect flowers and fruits? Please give guidance on the method: jujube generally has a high self-flowering seed-setting rate, but it does not have pollination trees, but the flower and fruit drop is serious and the yield is low, so jujube management should be strengthened during the flowering and fruiting period. detailed methods can be listed as follows: 1. Trunk girdling. Cut twice with a sharp knife ring 10-20 cm from the ground with a sharp knife ring, 0.4-0.6 cm wide and as deep as xylem. Peel off the skin and the wound can heal after 1 month. Precautions: (1) do not peel weak trees; (2) do not peel before girdling time, and the appropriate period is in full bloom; (3) do not ring peel year after year, and pay attention to prevent peeling mouth from being harmed by diseases and pests. 2. Foliar fertilizer spraying at flowering stage. Jujube trees often encounter drought or dry and hot wind during the flowering period, which affects the fruit setting rate. Generally spraying 0.3% urea or trace element solutions such as boron, manganese, zinc, iron and so on, all have obvious yield increasing effect. 3. Do not spray pesticides during flowering. 4. Spraying auxin can increase fruit setting rate and yield. 5. Release bees in jujube orchard. Jujube is an insect-pollinated flower, and the rate of fruit setting can be increased by using bees to strengthen pollination.
