In most mountainous areas of China, the wild jujube resources in the hills are rich in resources, and can be directly grafted into jujube seedlings by using jujube. In the place where the jujube resources are lacking, the jujube nuclear seedlings can also be grafted into winter jujube. First, use well-developed mature jujube fruit and water to wash away the outer skin, then soak for 50 hours. In the beginning of December, select the 0.5m deep pit in the shade, put 10cm thick wet sand, and mix the jujube core and sand into the pit. The straw mat and the soil cover are tight, so that the temperature inside the pit is maintained at 3 to 10 ° C and the humidity is 90%. The fertile sandy loam soil was selected and planted in batches according to the germination. The row spacing of the cultivated rootstocks was 5 cm × 30 cm, and the water was poured after the sowing, and the soil was covered with 3 cm, covered with a mulch or a shed film. After the emergence of the seedlings, the membrane is exposed in time, so that the buds are exposed, and timely cultivating, weeding, fertilizing, fighting, and pest control, the seedling height is 20 cm. Prevention and control of pests and diseases of winter jujube seedlings. Common insect pests of winter jujube include: jujube scorpion, jujube armyworm, yellow thorn moth, heartworm and other pests, combined with local actual conditions and timely prevention and control, jujube leaf rust, from mid-July to early August, late August to mid-September Each spray once 1:200 times Bordeaux mixture; the incidence of powder rusting 1000 times liquid, can control the disease. Jujube madness: For light disease trees, cut the mad branches before the leaves, and cut the rings before germination. After transplanting in the field, after thawing in the spring of the next year, the jujube seedlings that have been smelted in the greenhouse will be transplanted into the field for cultivation. The plant spacing will be 20cm×40cm, and the work of water and fertilizer management and pest control will be strengthened. The spring of the next year can be used for afforestation. . The winter jujube seedlings belong to the arbor-type tree species. No matter the seedlings or the seedlings, the growth of the main axis in the first 4 years greatly exceeds the growth of the lateral branches, and the growth of the better-growing seedlings can reach more than 1 meter.
