Jujube trees are also planted like other fruit trees. Planting large holes is appropriate. The width and depth of the holes must not be less than 70 cm, either square or round. When digging a planting hole, topsoil and subsoil should be stacked separately, and the bottom of the hole should be leveled to avoid being in the form of a pot bottom to prevent nesting. About 30 kg of organic fertilizer is applied to each hole, which is mixed with the topsoil and filled into the hole to make it become a mound in the middle and low around. After the seedlings are planted, the roots are stretched and the remaining topsoil is filled. When filling the soil, raise the seedlings upwards, and place the subsoil on the upper layer to facilitate the sun and accelerate the ripening. At the same time, we should pay attention to practicality and make the root system in close contact with the soil. Buried soil should not be too deep or too shallow. If the soil is buried too deeply, the ground temperature in the lower part of the hole is low, which is not conducive to the development of the root system; if the buried soil is too shallow, the root system will be easily exposed and hinder the survival, and it is also not conducive to drought resistance of the seedlings. When operating, it is better to match the depth of the original soil. Excessive soil can be used as a tree plate for timely irrigation and solidification, and further to make the root system and the soil close. After the irrigation water infiltrates, it can be covered with loose soil and cultivated into a hill shape to keep the water and prevent the seedlings from shaking, which is beneficial to survival. If the seedlings lose water before planting, the roots of the seedlings can be soaked in water for one day to allow them to suck enough water to plant them again. The forestry bureau of Yangqu County, Shanxi Province, tested and when planting, with 0.1% concentration of naphthaleneacetic acid or indole butyric acid, or rooting powder 0.05% concentration solution, dipping seedling roots for 5 to 10 seconds, the survival rate has been significantly improved. And it can promote the growth of roots and aboveground parts. In recent years, after planting jujube, some areas immediately covered planting holes with a plastic film of about 1 square meters, and they were smeared with fine soil. The surrounding area was compacted, leaving no gaps to prevent leakage and being blown away by the wind. In this way, moisturizing and warming can be beneficial to the healing of root wounds, and the survival rate can be greatly improved. For jujube seedlings that are never finished, attention should be paid to burying the roots with wet soil to prevent water loss from seedling roots and affect survival after planting. Jujube trees have "blister" and "back bud" phenomenon. The newly planted jujube trees did not sprout in the same year and should not be removed. In the coming year, these jujube trees may also germinate. The phenomenon that the sprouts that germinate after being planted and dried up for a while is called "return buds." The appearance of the above phenomenon is caused by poor seedling quality, poor root system, or improper management after planting. When this happens, if the seedlings are not dry and discolored, they still need to continue to manage, apply fertilizer and water, and properly loosen the soil to promote their survival. After the seedlings are alive, management must be strengthened. According to soil moisture, timely irrigation, loose soil to protect soil, reduce soil moisture evaporation, and pay attention to weeding to prevent grassland. To make the soil surface soft, moist, no weeds. Coastal areas in Shandong and Hebei provinces have improved the survival rate of jujube trees on the saline-alkali land and have achieved successful experiences. The practice is to dig a planting hole before the rainy season and leaching with rainwater to reduce the salt content of the soil inside the hole. Fill the pits after the rainy season to prevent efflorescence. When planting in the spring of the following year, open up the soil and apply organic fertilizer to the bottom of the hole. Fill in the soil around the roots of the seedlings. When filling, make the hole surface 15-29 cm lower than the surrounding ground. After planting, it is often necessary to loosen the surface of the cavern to reduce the evaporation of soil moisture, so as to slow the rate of returning salt in the soil inside the cave. After adopting this set of measures, the survival, growth and development of the jujube planted on the saline-alkali soil are all good.
