Winter jujube seedlings generally sprout around April 15th, and open when the flowering amount reaches 40% around June 1-15. The part of the armor is not in the main pole, but not on the branches. Generally, the saplings can open 3/5 branches, the weak trees are opened less, and more branches are used as vegetative branches. The thick branches of a diameter of about 2 cm have a width of 6-8 mm, and the branches below 2 cm are 4-5 mm thick. The South is slightly wider. It usually takes 30-50 days for a mouth to heal. It starts from 3 to 5 days after the opening of the nail and wipes it with a 10% chlorpyrifos 300 times for 7 days until the mouth is healed and wiped two or three times. If the mouth of the mouth is healed too early, it can be stripped under the mouth of the mouth; if the mouth is healed too late, the lower part of the skin should be scraped off, smeared with 920, then wrapped with a cardboard clip, and wrapped with a plastic film on the outside. A mouth heals. Winter jujube seedlings are trimmed, and the jujube trees in the early fruiting stage should adopt the technical measures of adjusting the branch position, improving the light, cultivating the branch group, promoting its nutrient turn, and transforming it from vegetative growth to reproductive growth; It is necessary to implement a balanced tree, adjust the structure of the tree, adjust and improve the lighting conditions, and promote its stable production and high yield and successive years. The pruning technique is relatively simple. There are few jujube branches, and the winter pruning only carries out the cultivation of the backbone branches, the adjustment of the subordinates of the branches and the renewal of the senescence branches. In the orchard of some of the jujube grains in the city, only a few thin branches and short cuts are carried out in winter. Summer pruning is mainly carried out around the preservation of flowers and fruit preservation. After the winter jujube seedlings are sprayed, 920 (15ppm) (72% 920, 1g water 100 kg) plus 0.1% urea solution, can also spray borax, must be single spray, spraying time before 10 am, 4 pm after that.
