Jujube trees have more than three tricks

First, rational control. Before flowering (about the beginning of May), each tree topdressing urea 0.5 ~ 0.75 kg, the initial result tree topdressing 0.25 kg, after the flowering young fruit development period (in late June) and then apply a nitrogen, phosphorus, potassium compound fertilizer About 0.75 kg per plant. Spraying 10-50ppm gibberellin solution or spraying 0.3% borax solution at full flowering stage at the early stage of flowering can significantly increase fruit setting rate.

Second, irrigation before flowering, flowering water spray. If the soil is too dry before flowering, it should be timely watered to ensure stable fruit setting. Spraying water every 2 to 3 days during the flowering period of jujube trees can promote pollination and fertilization and increase the fruit setting rate.

Third, the Zaoyuan bee. Jujube is a typical insect-like flower, and flowering at the flowering stage can increase the fruit setting rate. Generally, a box of bees can be placed every 6 to 10 mu of jujube garden.
