Core Viewpoint - The Zhenning Honey Peach Association and the Industry Association have jointly released the "2025 Zhenning Honey Peach Harvest Grading Standard Guidance," which outlines specific quality standards for the harvesting of honey peaches to maintain brand integrity and product quality [2][11]. Group 1: Harvesting Standards - The harvesting standards include a minimum sugar content of ≥15%, maximum acidity of ≤0.85%, and a hardness greater than 9 Kgf/cm² as core indicators for harvesting [4][15]. - The guidance suggests conducting 2-3 concentrated harvests during the market period, ensuring that the fruit reaches the specified sugar and acidity levels before harvesting [14][15]. - The sensory standards require the fruit skin to be light yellow or light yellow-green, with a crisp texture and pleasant aroma, free from physical damage and pests [18][19]. Group 2: Harvesting Requirements - The guidelines stipulate that pesticide application should cease 15 days before harvesting, and no artificial watering should occur 5 days prior to harvest [20]. - Harvesting should be done on sunny days, avoiding rainy or dewy conditions, and the collection area should be cool and well-ventilated [21][22]. - Harvesting containers must be smooth and clean, treated with a disinfectant solution prior to use, and lined with cushioning material to prevent damage to the fruit [23][24]. Group 3: Grading Standards - The grading standards categorize the fruit into four grades based on size: Grade A (35-39 mm), Grade 2A (40-44 mm), Grade 3A (45-49 mm), and Grade 4A (50 mm and above) [30][31]. - These standards provide a scientific basis for the 220,100 acres of honey peach cultivation in the county, ensuring consistent quality and marketability [5].
