Pinggu Peach is well-known both at home and abroad for its large, colorful, high-intensity, and non-pollution, and is favored by consumers. In April 2006, the General Administration of Quality Supervision, Inspection and Quarantine approved the protection of GI products for Pinggu Dao. Temperature The annual average temperature is 11.5°C, and the average temperature from May to August is above 20°C. The average daily temperature in July is 26.1°C, while the average temperature in the coldest month is -5.5°C. Extreme maximum temperature 40.2 °C, extreme minimum temperature -26 °C, according to the 80% guarantee rate, the accumulated temperature greater than 0 °C 4470 °C, the accumulated temperature greater than 10 °C 4121 °C ~ 4945 °C, the average annual frost-free period 191d, the longest 205d, the shortest 160d. There is a large temperature difference between day and night, rain and heat in the same season. illumination The annual sunshine duration is 2729.4 hours. The average annual sunshine percentage is 62%. The amount of solar radiation is 559.24 kJ/m2. Sunshine hours were the highest in May, at 287.3 hours, compared with 268.9 hours in June. precipitation The average annual precipitation is 639.5mm. Precipitation seasons are unevenly distributed. Precipitation in winter is only 9.6mm, accounting for 1.5% of the annual precipitation. In general years, from October to May the following year, there is arid and lack of rain, and in summer the most, the annual average is 479.1mm, accounting for 74.9% of annual precipitation. %. Evaporation The average annual evaporation is 1762.3mm, which is the highest in May. Evaporation is far greater than precipitation is the main characteristics of the climatic conditions in this area. Water resources With abundant water resources, the annual average annual runoff of surface water is 310 million cubic meters (including 110 million cubic meters of surface water). The annual average amount of groundwater recharge is 297 million cubic meters, and the amount of groundwater recoverable is 220 million cubic meters per year. soil Sandy loam and light loam. The pH value is 6.0 to 8.0, the salt content (in terms of NaCl) is ≤0.14%, and the organic matter content is ≥0.8%. Delicious mysteries First, independent water system, excellent water quality. There are many rivers in Pinggu, and there are more than 10 rivers and seasonal rivers in the year. The average annual runoff is 450 million cubic meters. Rich in groundwater resources, with a reserve of 450 million cubic meters, it is an independent water system with good water quality and no pollution. It is called "Shen Shui". Second, sufficient sunshine, large temperature difference between day and night. Pinggu County is an open terrain surrounded by mountains on three sides and open in the southwest. The piedmont warm belt stretching over 100 kilometers is very suitable for fruit production. Here, the average total light radiation is 5103 Joules per square meter, and the average daily sunshine rate is 58%. It is in the long-wave radiation zone. The temperature difference between day and night is large, which effectively forms the accumulation of peach peach nutrients and nutrients. Third, unique soil, rich in nutrition. Pinggu Plain is formed by the impact and siltation of the Suihe River and the Weihe River. It belongs to the slightly acidic, sandy, breathable soil. With the unique geographical features of the surrounding mountains that store a large number of potassium-rich volcanic rocks, it is suitable not only for growing peaches, but also for natural peaches. The growth provides a lot of micronutrients. Fourth, Pinggu Peach strictly in accordance with the standard peach fruit production requirements of the technical regulations, scientific thinning and fruit thinning, increase the amount of farm fertilizer, as far as possible with or without chemical fertilizers, eliminate the use of chemical pesticides, to ensure that the fruit production of intrinsic quality and food safety . Pinggu Peach was 100% liquified at the time of export inspection. None of the pesticide residues exceeded the standard and reached the green food standard. According to the "Regulations on the Protection of Geographical Indications Products", the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) organized a review of applications for protection of geographical indications of Pinggu Da Tao. After passing the review, it was approved to implement the protection of GI products for Pinggu DaPin from April 16, 2006. protected range The protection scope of Pinggu Da Tao’s geographical indication products shall be based on the scope of the “Letter of Defining the Protection Range of National Geographical Marks of Pinggu Da Tao†of the People’s Government of Pinggu District of Beijing City (Jingping Zhengwen [2005] No. 65), which is the jurisdiction of Pinggu District of Beijing Municipality. Administrative regions. Quality and technical requirements (a) Variety. Okubo, Qingfeng (Beijing No. 26), Jingyan (Beijing No. 24), Yanhong (Green No. 9), August Crisp (Beijing No. 33), Yanfeng No. 1, Lu Wangxian, Huayu, Dahongtao, Twenty In the first century, there were 10 white peach varieties. (b) site conditions. No heavy metal pollution of sandy loam and light loam. pH 6.0 to 8.0, salt content ≤ 0.14%, organic matter content ≥ 0.8%. (c) Cultivation and management. 1. Breeding of seedlings: The rootstock was selected as the rootstock, and the scion was grafted and propagated from the superior plants. 2. Tree: "Y" or naturally happy. 3. Planting density ≤ 55 strains/667 square meters (mu). 4. Fertilization: The main application of decomposed organic fertilizer. (d) Harvesting and storage. 1. Harvesting: The maturity of the fruit can be harvested when it reaches seven maturity levels. 2. Storage: Peach must be refrigerated for long-distance transportation. Precooling should be carried out before the fruit is put into storage. The pre-cooling temperature is 4°C, the storage temperature is 0°C to 3°C, and the storage time limit is within 15 days. (five) quality characteristics. 1. Sensory characteristics: must meet the characteristics of this species. (1) Okubo: with red, single fruit weight ≥ 225 grams, soft and juicy, dense meat, sweet and sour taste. (2) Qingfeng (Beijing No. 26): red and yellow, single fruit weight ≥ 150 grams, soft and juicy, sweet. (3) Yan Hong (Green No. 9): The ground color is milky, the fruit surface is red, the single fruit weight is ≥ 250 grams, the meat is dense, the juice is plentiful, sweet and fragrant. (4) Jingyan (Beijing No. 24): Yellow and white background, red fruit surface, single fruit weight ≥ 250 g, fine and dense flesh, soft, scented and sweet.

The large fruit tastes less than Jiu Bao and is quite expensive. Special signs use Producers within the scope of protection of Pinggu Da Tao's geographical indication products may apply to the Pinggu District Bureau of Quality and Technical Supervision of Beijing for the use of “Special Marks for Geographical Indication Productsâ€, which shall be approved by the AQSIQ.
