Jujube is a fruit with rich nutritional value, and its cultivation techniques are as follows:
Land selection: Choose deep, fertile, well-drained sandy soil for planting. Before planting, the land is prepared to a depth of about 30 cm, removing weeds and stones to make the soil soft.
Selection of varieties: Choose jujube varieties that are suitable for local climate and soil conditions for planting.
Sowing: Sowing in spring or autumn, generally by strip sowing or hole sowing. The spacing of the strip sowing row is 2 meters, the depth is 3-4 cm, and the amount of seed per mu is 1-2 kg. The row spacing of hole sowing is 1 meter 1 meter, 3-4 seeds are sown in each hole, the depth is 3-4 cm, and the amount of seeds per mu is 05-1 kg.
Reasonable dense planting: Determine the planting density according to soil fertility and management level. Generally speaking, it is advisable to plant 100-200 plants per mu.
Fertilization: Moderate fertilization is required during the growing period to provide adequate nutrients. Generally, fertilization is applied 2-3 times a year, and each application is applied with well-rotted farmhouse fertilizer or compound fertilizer.
Watering: Timely watering is required during the dry season to keep the soil moist. However, in the rainy season, it is necessary to pay attention to drainage to prevent root rot caused by stagnant water.
Pruning: Pruning is required during the growing process to keep the tree aesthetically pleasing and airy. Pruning is generally done in the spring to remove overly dense and diseased branches and allow the canopy to ventilate and let in light.
Pest control: Regularly check the growth of jujube trees, and find and control pests and diseases in time. Generally, the combination of biological control and chemical control is adopted, and low-toxicity and high-efficiency pesticides are used for control.
Harvesting: Jujube needs to be harvested in time after maturity. Generally, manual or mechanical picking is used. After picking, it should be washed, dried and packaged in time for sale and consumption.
In short, in order to successfully plant jujube, it is necessary to choose the right variety and land, and carry out scientific management measures such as land preparation, sowing, fertilization, watering, pruning, and pest control. At the same time, attention should be paid to reasonable dense planting and timely harvesting to ensure the quality and yield of jujube.
