Abstract:Jumeiren is a new variety of soft seed and red skin derived from a cross between Hongruyi and Wonderful. In 2007, Hongruyi was used as female parent and Wonderful as male parent, to cross, and hybrid seeds were obtained in the same year. Layer treatment in winter. Sowing in 2008, 518 hybrid seedlings were obtained. A small number of hybrid seedlings bearing fruit in 2011. In 2012, 26 hybrid seedlings with good fruit quality were selected for regional trials using grafting and cuttage methods in experimental gardens of Yicheng District and Shizhong District, Zaozhuang City, Shandong province, and Shangqiu City, Henan Province. In 2013, Zj2007-26 individuals with excellent performance were propagated by cuttage. After 6 years of systematic observation, it was found that the superior plant had large fruit size, soft seed, sweet and sour flavor, high soluble solid content. Jumeiren had characteristics of distinctness, uniformity, stability, and the fine comprehensive characteristics. This species is a small tree, attaining a height of 2.5 m-3.0 m. The growth of trees is moderate, and the crown isnaturally rounded. The colour of trunk is taupe, young branches are green-gray, branch-forming force is strong. It has more branch thorns. The leaf shape is long elliptic, with 6.44 cm length and 2.1 cm width. Flowers is with dark red, single, higher proportion of bisexual flowers. The fruit is nearly spherical, with an average longitudinal diameter of 10 cm, an average transverse diameter of 11.85 cm, and a fruit type index of 0.84. The fruit surface is smooth, the skin dark red, the calyx tube closed, and the ribbed ribs are not obvious. This species is early maturing variety, surface light red. The average fruit weight is 452 g, the average weight per 100 arils is 44.6 g, the seed hardness is 2.12 kg·cm-2 , the soluble sugar content is 15.9 %, the ratio of sugar to acid is 50.0. The seeds purplish is red with a sweet and sour flavor. The fruit development period is 120 d and it matures in mid-to-late July in Mengzi city, Yunnan province. It is suitable to be cultivated in Yunnan province, Sichuan province, and other pomegranate producing areas in South China. Using facilities for cultivation to prevent tree freezing injury in northern pomegranate producing areas. Orchard should choose the section with deep soil layer, good site conditions and water irrigation conditions. This species likes strong light and warm climate. The absolute minimum temperature should above -10 ℃. Spacing in the rows and spacing between rows are(2 m~2.5 m)×4 m. Fertilization period includes fertilizer in autumn, and topdressing before flowering, young fruit expansion stage, fruit color turning stage. The fertilizer should be applied deep to 30 cm~40 cm. Watering period includes before germination, before fruit expansion and before freezing. Pomegranate is afraid of waterlogging, pay attention to drainage in rainy season. Shaping should be the main sparse layer-shaped, spindle-shaped, “Umbrella” type or “Inverted pyramid” tree, set dry height 80 cm -100 cm. Pruning is mainly used in spring, summer and autumn, the main methods are sprouting, removing sprout, thinning, picking and rubbing branches, truncation is only used in tree rejuvenation. In the growing season, it is necessary to take agricultural and physical prevention and control as the basis, biological prevention and control as the core, chemical prevention and control as the supplement, give full play to the control role of natural factors, and comprehensively prevent and control the occurrence and spread of diseases and insect pests. After defoliation and before sprouting, the whole garden sprayed with Bubomedo 3°~5° stone sulfur mixture. Put on white paper bag in time after physiological fall, spraying insecticide and fungicide before bagging. Hanging black light lamp, frequency-vibratory insecticidal lamp to control peach borer, yellow thorn moth and other pests.
