The winter jujube seedlings are bent and buried in the soil for heat preservation and cold protection. The annual jujube seedlings are less than 1 m high, and the small-sized winter jujube seedlings with a base diameter of 1 cm or less are planted, and then the jujube seedlings are gently bent down. In order to prevent the breakage of winter jujube seedlings, the soil pillows were piled up in the head of Dongzao jujube, and the winter jujube seedlings were buried with soil, first covering 20 cm thick soil, then gradually thickening the soil with the decrease of temperature, and adding the soil to the local frozen soil layer in the harsh winter. In the following year, as the temperature increases, the soil cover will be gradually removed, the cover soil will be removed before germination, and the seedlings will be corrected. The management of winter jujube seedlings after grafting is an important measure to ensure the high quality and firmness of winter jujube seedlings. It takes about half a month from the grafting of winter jujube seedlings to the scion. Since the nutrient substance germinates at the base of the rootstock, it should be removed in time to facilitate the germination and growth of the scion, and the grafted seedling is used as the scion. The strong jujube tree head can grow directly, or it can be planted first. In order to stimulate the main bud to form the jujube head, the jujube should be hung and cut at about 0.5 cm at the bottom. When the seedlings grow to 1,520 cm, they should be tied up with wooden sticks or bamboo rafts in time.  The seedlings of the splicing or abdomen are also required to be tied up; when the grafted seedlings and rootstocks have healed firmly, the plastic film is cut longitudinally with a knife to prevent the scarring of the seedlings and the growth of the seedlings; from June to July Timely topdressing, every 6 6 7 m 2 topdressing urea 15 ---20 kg or ammonium sulfate 30 ~ 40 kg, timely watering after topdressing.
