Characteristics of the Xiahui No. 1 Peach Variety
Bred by the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences, from a cross of Zhaohui × Zhaoxia. The original code was 75-8-6, and it was named in 1985. The average single fruit weight is 130 g, and the largest fruit weighs 210 g; the ground color of the skin is creamy yellow, with a rose-red blush on the top; the flesh is white to creamy yellow, with a sweet flavor; soluble solids are 9%-10%. Clingstone. The tree vigor is relatively strong, and the tree posture is semi-spreading. All types of fruiting branches can bear fruit, with many compound flower buds, and it is high-yielding. However, the pollen is sterile, so pollinizer trees need to be planted. In the Zhengzhou area of Henan

Control Methods and Key Technical Points for the Peach Fruit Borer in Plum Trees
Symptoms: The hatched larvae bore into the fruit from the base of the fruit stalk, tunnel along the pit into the fruit to feed, and the gum flowing from the bore hole together with the brown frass excreted by the larvae sticks to the fruit surface, causing the tunnel to overflow with frass and making the fruit unfit to eat. Control method: During the peak egg-laying periods of the first and second generations of adults in April to May, when most of the eggs on the fruit turn red, promptly spray 2.5% deltamethrin at 2500 times dilution, 50% phoxim emulsifiable concentrate at 1000 times dilution, or 40% omethoate at 1000 times dilution.

Detailed Explanation of Integrated Pest Management (IPM) Technology in Peach Orchards
The 6 core components of IPM technology in peach orchards: (1) Agricultural control measures for pests and diseases in peach orchards. During winter pruning, remove diseased and pest-infested branches and mummified fruit, and destroy them in a centralized manner; adjust the tree structure, improve ventilation and light penetration conditions, and strengthen tree vigor; (2) Frequency-vibration insect-killing lamp technology for trapping and killing pests. Install 1 insect-killing lamp per 3.3 hm2 of orchard, and use it from early April to mid-October, which can achieve a good insect-killing effect; (3) Sugar-vinegar basin technology for trapping and killing pests. Starting in mid-March, placing sugar-vinegar basins in the orchard has a clear effect on trapping and killing overwintering-generation adults of the peach leafminer moth; (4) Sex phero

Characteristics of the peach cultivar Chashan Zaomi
1 Breeding process In July 1994, 169 well-developed seeds from pure Yuhualu peach obtained by natural pollination were collected. After stratification treatment, they were sown and raised as seedlings. In 1995, 126 progeny seedlings were obtained, numbered 001--126, and in 1996 they were planted at the Chashan practice base of Linyi Normal University. From 1998 to 1999, they fruited successively. In 2000, 5 better-performing lines were top-grafted in the high-tech experimental orchard and production orchard of the Chashan base. After 3 years of trait observation, No. 026 showed early fruiting

Storage Methods and Technical Key Points for Peaches, Plums, and Apricots
(1) Room-temperature storage: Peaches are not suitable for room-temperature storage, but due to the needs of transportation and shelf-life preservation, certain measures can be taken to extend the room-temperature freshness life of peaches. 1. Calcium treatment: Soak peach fruit in a 0.2%-1.5% CaCl2 solution for 2 min or vacuum-soak for several minutes, drain the liquid, and leave bare indoors; for mid- and late-maturing cultivars this can improve storability. 2. Heat treatment: Soak fruit in constant-temperature water at 52°C for 2 min, or hold in steam at 54°C for 15 min, which can

Storage and Fresh-keeping Techniques for Peach, Plum and Apricot Fruits (Part Two)
III. Pre-storage Agricultural Measures for Peach, Plum and Apricot 1. Selection of Storage Varieties Early-maturing varieties are not tolerant of storage and transport, such as honey peach and Wuyuexian. Mid- and late-maturing varieties have better storage and transport tolerance, such as Feicheng peach, Qingzhou honey peach and Shaanxi winter peach, which are relatively tolerant of storage and transport; varieties such as Okubo and Gangshanbai, Yanhong also have good storage and transport tolerance. Clingstone varieties and soft-fleshed varieties have poor storage and transport tolerance. The storage and transport tolerance of plum and apricot is similar to that of peach; varieties such as Niuxin plum and Hebei rock sugar plum have good quality and are also tolerant of storage. 2. Pre-harvest Agricultural Technical Measures Pre-harvest

What are the characteristics of the economic traits of the Xinchuan Zhongdao peach fruit?
Economic traits of the fruit: The fruit is large, with a single fruit weight of 260-350 g. It is round or oval, with a flat fruit apex and an inconspicuous suture. The fruit is bright red with a gorgeous color, the fruit surface is smooth, and the fuzz is sparse and short. The flesh is yellow-white, pale red near the pit, semi-clingstone, with a small pit, and an edible rate as high as 97%. The flesh is crisp and firm, and juicy. At room temperature, it can be stored for 1015 days, has good marketability, and is extremely tolerant of storage and transport. The fruit has a sugar content of more than 13.5%, low acidity at 0.15%, is sweet and sour and palatable, with a distinctive flavor and rich aroma, and

What methods are there to prevent chilling injury in stored peaches?
Peaches are climacteric fruits, with a respiratory peak and poor storage tolerance; at room temperature they can be stored for only a few days, and most cultivars can be stored at 0°C or below for only 15~30 days. After harvest, peach fruit enzyme activity and respiration are both very strong, so at room temperature the fruit easily softens and rots; low temperature, low oxygen and higher carbon dioxide can inhibit respiration and enzyme activity. At 0°C, using film bag packaging and controlled atmosphere storage, controlling 1%~2% oxygen and 3%~5% carbon dioxide, and applying an ethylene absorbent, the fruit can be stored for 2 months, but care must be taken

Detailed Explanation of Key Technical Points for Greenhouse Peach Cultivation and Management
I. Early training, early shaping, early fruiting. Because greenhouse peach trees are planted at high density, in order to obtain relatively high early income, shaping and flower bud development must be completed within one year: vigorously promote growth in the early stage for early shaping, then control growth in the later stage to produce more flowers. When shaping, whether using the slender spindle form or the "Y" form, yield must be given top priority. Not only should pinching be done multiple times under the premise of adequate fertilizer and water supply to promote more secondary and tertiary branches, but permanent fruiting must also be considered, that is, the branches being trained should not be tipped so they maintain a certain

New extremely late-ripening peach variety Qiuhong Wanmi has arrived
China has few extremely late-ripening peach varieties. Existing varieties such as Zhonghua Shengtao and Zhonghua Shoutao have poor cold resistance, resulting in a relatively small market supply in late October. An excellent strain, 'Yuhong Wanmi', was selected from the local excellent peach resource strain 'Qiumi' in Fengrun District, Tangshan City, Hebei Province. In December 2006, it passed the examination and approval of the Hebei Provincial Forest Tree Variety Approval Committee and was named 'Qiuhong Wanmi'. Variety characteristics: strong tree vigor, semi-spreading tree habit, average trunk circumference of 48cm for 8-year-old trees, tree height 3.1m, crown width
