Trimming in three situations. If the jujube tree enters the aging period, the growth momentum of the jujube tree gradually weakens, the new jujube head that germinates decreases, the secondary branch begins to die, and the stem branches have a light pole phenomenon, and 1/3 of the total length of the stem branches can be cut off to stimulate the pumping. New jujube head; when the juniper tree tree vigor obviously weakened, the backbone of the majority of bare bald, apex back to dry, the second branch appeared a large number of deaths, can be selected in the branches of the vitality of strong, extended outstretched stocks and lurking The buds saw 1/2 of their total length so that they germinate new branches. At the same time, they strengthen tree management and raise trees for 1 to 2 years (without opening A); when the jujube tree is extremely old, the backbone branches are severely rejuvenated, and effective dates Shares are reduced, and stocks and potential buds can be selected, sawing out 2/3 of the branches, causing them to sprout new branches, re-forming the crowns, and then strengthening the trees under the tree to manage the trees for 2 years (without opening). At the same time, to update the old trees, we must pay attention to the relationship between master and slave, and proceed in order. Cut out the mouth with a wax coating to prevent cracking of the wound. Store the rain to rot. Backbone branch updates must be completed at one time and cannot be performed in batches. Most importantly, renewal pruning should be carried out on the basis of strengthening the management of underground manure and water.
