1, teapot jujube can be planted on both sides of roads and around courtyards, which requires loose and fertile soil and high organic matter content. If the soil is poor, it is necessary to cultivate garden soil, pond mud or soil fertilizer to improve the soil. Select strong seedlings to plant in the pit in February and March; If potted, the diameter of the spout should be 50 ~ 100 cm. No matter how you plant potted plants in the field, you should apply sufficient organic fertilizer and spray sufficient root water.

2. Shaping and pruning: the ornamental trees are better in natural shape or small crown and sparse layer. After planting, the trunk is 30 ~ 40 cm high and divided into 3 ~ 4 main branches or culture dry layers; The main branch spacing is 5 ~ 15cm, so jujube trees should be dwarfed and reduced if they are potted for viewing. Choose 2 ~ 3 auxiliary main branches and appropriate auxiliary branches for each main branch. The pruning of ornamental jujube is mainly in early winter and summer, mainly pruning long branches, weak branches, dead branches, disease and insect branches and branches outside the crown that disturb the tree. In the peak season of growth, we should pay attention to wiping buds, thinning branches, removing cores and pulling branches to cultivate a beautiful and unique crown.

3. Fertilizer and water management: during the two-year planting period, nitrogen fertilizer was mainly applied, and phosphorus, potassium, fertilizer and trace elements were applied together. After 65 and 438+00 days of germination, 5 ~ 65 grams of urea and 438+00 grams of thin human and animal manure can be applied, and then topdressing should be done every 40 ~ 60 days, and the dosage will increase with the expansion of crown. In mid-June, 5438+ 10, base fertilizer and overwintering fertilizer were topdressing, mainly organic fertilizer and phosphate fertilizer. Adult jujube trees should be topdressing with pre-bud fertilizer, flower wilting fertilizer and fruit picking fertilizer once a year. If potted plants need to supplement strong fruit fertilizer, organic fertilizer or compound fertilizer should be used as the main fertilizer. The ratio of nitrogen, phosphorus and potassium is 1: 0.5: 0.8. In addition, spraying 0.2% borax, 0.2% potassium dihydrogen phosphate, 0.3% urea and rare earth compound foliar fertilizer on leaves from April to June every year can promote fruit development and prolong leaf life. Irrigation and drainage should be carried out in time during flowering and fruit expansion.

4. Flower and fruit management: Zizyphus jujuba is a multi-flowered tree species, and the natural fruit setting rate is less than 2%. In order to improve the fruit setting rate, it is necessary to strengthen the management of flowers and fruits. First of all, we should adjust the nutrient distribution of trees, pick tender branches and cut short hair branches. If the trees are lush, we should cut off roots or girdle them at the right time. Secondly, spraying 15 ~ 20mg/kg gibberellin once when most fruiting branches of the whole tree bloom for 5 ~ 6 times; Third, spraying water during flowering can promote pollen germination, and spraying water should generally be carried out in the evening or early morning when the temperature is low; In addition, spraying trace elements such as boron, zinc, manganese and rare earth or special flower fertilizer at flowering stage can also promote fruit setting. Fruits crack easily when they are ripe. Covering the tree with plastic film and irrigation in time can prevent the fruit from cracking a lot.

6. Disease control: Ziziphus jujuba mainly includes jujube rust, jujube madness, anthracnose, inchworm, peach borer, red spider, scale insect, longicorn beetle and so on. Its control methods are mainly to strengthen management, enhance tree vigor, and timely select high-efficiency, low-toxicity and low-residue chemicals for spraying. The specific control measures can be the same as the cultivation points.
