Alias Mozi jujube, Hulu jujube (Hebei), medicinal gourd jujube (Gansu). Widely distributed, Shaanxi big litchi, Gansu Qingyang, Hebei Jiaohe, Qingxian, Xianxian, Quyang, Daming, Wei County, Shandong Leling, Wudi, Xiajin and other places are cultivated, the number is very small, sporadic planting around. Cultivation has a long history. The tree is strong, large and medium-dry, with a natural semicircle crown and open posture. The 23-year-old tree has a dry height of 1.1m, a stem circumference of 60cm, a height of 7.35m and a crown diameter of about 7m. The trunk is grayish brown, the skin is deeply cracked and is not easy to peel off. The jujube head is purple-brown, the growth potential is strong, the wood is soft, the growth is 50~80cm, the secondary branch naturally grows 5-7 nodes, and the acupuncture is well developed. The leather eyes are large and dense, round or oval, protruding, dehiscing. Jujube stock is large, cylindrical, long 2.6cm, coarse 1.2cm, lasting for about 8 years. The lifting force is strong, generally 3-5 per share, mostly up to 7-8, jujube hanging length 12~20cm, a few jujube hangers have secondary hanging growth phenomenon. The leaves are large or large, lanceolate, dark green, long 4.7~5.7cm, wide 2.3~2.7cm, apex acuminate, leaf base rounded, leaf level serrated shallow and sparse. There are more than 7 flowers in each inflorescence in the middle of jujube hanging. The flower is big, the zero grade flower diameter is 8mm, the first grade flower diameter is 7.5mm, diurnal blooming type. The honey plate is large and light yellow. The fruit is large and stone-shaped, with a constriction in the middle of the fruit, 2~3mm in depth and width, small in the upper part and large in the lower part. Vertical diameter 2.6~3.4cm, horizontal diameter 2.4~3.2cm, the average fruit weight is about 7g, the maximum fruit weight is 13.7g, the size is uneven. The fruiting pedicel is medium-long, medium-thick, medium-wide and medium-deep. Fruit apex flat or retuse, stigma remaining, inconspicuous. The pulp is thicker, green-white, fleshy, sweet, less juicy, suitable for drying, the quality of dried jujube is medium and low, and the drying rate is 50.5%. Fresh jujube contains 3033% soluble solids. The nucleus is large, fusiform or oval, longitudinal diameter 1.8cm, transverse diameter 0.9cm, weight 0.9g, edible rate 93.5%. The nuclear grain is deep, the nuclear tip is short, the nuclear surface is rough and the kernel content is low. As a result, root tiller propagation was used in a few producing areas, and grafting propagation was used in most producing areas. The root tiller seedlings began to bear fruit 2-3 years after planting, with poor fruiting, 1-13 nodes in the fruit-setting part, and 2-5 nodes in the main fruit-setting part, accounting for 73.33% of the total fruit-setting. The yield is low or medium, the tree in full fruit stage, the plant produces fresh jujube 15~25kg. In the producing area, it matured in mid-and late September, and the fruit growth period was about 100 days. The variety has strong adaptability, low or medium yield, medium-large fruit, medium-low quality, suitable for drying, rain resistance to cracking during maturity. There is a constriction in the middle of the fruit, the fruit is obviously divided into two parts, the shape of the fruit is strange and beautiful, and can be cultivated as a courtyard ornamental tree.
