The invention discloses a method for planting selenium-rich and SOD-rich jujube trees. The method comprises the following steps that 1, neutral alkali rich soil with sufficient lighting and even rainwater is selected as a site; 2, planting is carried out, wherein holes are dug every 1.5 m to 2.5 m, the distance between every two rows of saplings is controlled to range from 2 m to 3.5 m, and jujube tree seedlings with the height of 1 m to 3 m are planted; 3, nursery garden nursing is carried out, wherein weeds, miscellaneous trees and sundries on planting land and ridges are removed; 4, watering maintaining is carried out, wherein watering is carried out once every other 10 days, and watering is continuously carried out 3-6 times till the jujube tree survive; 5, the selenium-rich and SOD-rich jujube trees are cultivated, wherein nutritional factors are sprayed to the jujube trees in the growing period of the jujube trees; 6, picking is carried out, wherein after jujubes are mature, a manual picking method is adopted, jujube fruits are held with the hand, force is slightly applied in the direction opposite to the bending direction of fruit stems, and the jujube fruits naturally fall off. According to the planted jujube trees, after SOD enzymes are sprayed, the SOD average enzyme activity of each gram of jujube fruits is remarkably increased, the selenium content is obviously increased, and the effect of improving the nutritional value of the jujube fruits is very remarkable.
