The early yellow flat peach was bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences through hybridization using 8-21 as the female parent and a French flat peach as the male parent, and was named in 1997. It was introduced to Toutunhe Farm at the end of the last century. Through nearly ten years of trial planting observation, this variety is relatively suitable for the local natural conditions and can be developed and promoted in the **suburbs of towns along the economic belt on the northern slope of the Tianshan Mountains. 1) Overview of the introduction site. Toutunhe Farm is located in the western suburbs of Urumqi and belongs to the 12th Division of the XPCC. The soil is half sandy and half clay, and the soil pH is moderately acidic. It belongs to a mid-temperate semi-arid climate zone, with four distinct seasons,

Through nearly ten years of trial planting observation, this variety is relatively suitable for the local natural conditions and can be developed and promoted in the **suburbs of towns along the economic belt on the northern slope of the Tianshan Mountains. 1) Overview of the introduction site. Toutunhe Farm is located in the western suburbs of Urumqi and belongs to the 12th Division of the XPCC. The soil is half sandy and half clay, and the soil pH is moderately acidic. It belongs to a mid-temperate semi-arid climate zone, with four distinct seasons and a large day-night temperature difference. Winters are long, and annual precipitation is relatively low, but irrigation water is abundant. 2) Commercial traits of the variety. The fruit of the early yellow flat peach is flat, with a slightly concave top, a relatively deep suture, and symmetrical halves. The average single fruit weight is 180 g, and the maximum is 350 g. Near the fruit stem it is apricot yellow, and most of the fruit surface is rose red, making the appearance extremely beautiful. The flesh is orange-yellow, soft, juicy, with medium fiber, a sweet flavor, a slightly sour aftertaste, a rich peach aroma, and a pleasant fresh fragrance. Soluble solids 13%. 15%. The pit is small, semi-clinging, and the edible rate is high. 3) Biological characteristics. ① Phenological period. Cultivated in the Urumqi and Changji areas. Flower buds swell in early April, first flowering on April 10, full bloom on April 15-17, and petal fall and fruit set around April 20. Around June 28 the fruit expands and colors, the fruit growth period is 80-85 days, leaf fall begins at the end of October, and it enters the dormant period. ② Growth and fruiting habits. Young trees grow vigorously, and the crown is relatively open. Leaf glands are kidney-shaped, and the leaves are light green with a slight yellow tinge; the branches are relatively slender and long. The flowers are rose-like and naturally pollinated. Fruiting is mainly on bouquet-like fruiting branches and medium and long branches, and when heading back fruiting branches, longer cuts are preferable. The fruit-setting rate is high, so flowers and fruits should be thinned in a timely manner. 4) Management key points. ① To prevent fruit cracking, pre-flowering irrigation and fruit-swelling irrigation are crucial; calcium and boron micronutrient fertilizers can also be used, with control started in advance at flowering and fruit set. ② When pruning young trees, promptly remove competing branches on the upper part of each main branch and upright branches on the middle and lower parts of the back, and control vigorous water sprouts in the inner canopy. For 2-3 year old young trees, bend branches in autumn during water control so that they form a 45. angle with the ground. ③ In autumn, control water in a timely manner according to weather conditions to increase the degree of lignification of branches, which helps flower buds mature and ensures safe overwintering. Winter irrigation is especially important and must be thorough and fully soaked. ④ The main pests and diseases include powdery mildew, iron deficiency, peach fruit borer, red spider mites, and aphids, and chemical agents should be used promptly for prevention and control. To prevent damage from mice gnawing, scatter rodenticide around the crown and at mouse holes before burying the soil for overwintering.
