Five tricks to promote jujube trees
Jujube trees have a large amount of flowers, but the fruit setting rate is very low, generally accounting for only about 0.6% of the flower amount. The fruit setting rate of old trees is lower, and some are less than 0.1%. So how can we encourage jujube trees to bear more fruit? Pruning and heart-plucking jujube trees are usually pruned for the first time when they germinate in spring, and summer pruning is carried out at the full and late flowering periods. Wipe away the useless shoots and other branches that consume the nutrients of the tree trunk and the stems of the inner trunk. When the new jujube head grows to 25 to 30 cm, topping is performed to control the growth of developing branches, increase the growth of secondary branches, and promote fruit setting. Open nail (ring cutting) For jujube trees in the vigorous growth period, the phloem is cut by opening the nail, so that the nutrients made by the leaves are concentrated for flowering and fruit setting. Kaijia is suitable for trees with a diameter of 10 to 15 cm or more. The proper period for opening a nail is the blooming period. The specific method is that the trunk is cut 10-20 cm from the ground, the width is 0.3-0.5 cm, and the depth is up to the xylem. After peeling, the wound is wrapped with plastic film. Before rational flowering (from late April to early May), each large tree topdressed with 0.5-0.75 kg of urea, the initial fruit trees topdressed with 0.25 kg, and nitrogen was applied again after the flowering young fruit development period (mid-late June) , Phosphorus, Potassium compound fertilizer, 0.75 kg per plant. Spraying 10%-50% gibberellin solution in the early flowering period or 0.3% borax solution in the flowering period can significantly improve fruit setting rate. Irrigate before flowering. If the soil is too dry before flowering during flowering, it should be watered in time 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 improve fruit setting rate. Putting bee jujube flowers in the jujube garden is a typical insect vector flower. Generally, a box of bees is placed every 6 acres to 10 acres of jujube garden.
