Changping is located in the suburbs of the capital, 30 kilometers away from the urban area. The Yanshan Mountains traverse the east and west, forming a natural barrier. The north is bounded by the Yanshan and Nanzhao Jingmi diversion canals, and the middle is a narrow hilly hilly landform from east to west. It is the "warm belt in front of the mountain." At the southern end of the warm zone, the Jingmi diversion channel flows slowly from east to west, separating the mountains and plains organically, such as the same natural “air conditioning” to regulate the regional microclimate. The water that Changping apples drink is taken from the deep layer of water filtered by layer below 200M. From the test results of Beijing Municipal Center for Disease Control and Prevention, we can see that the water contains zinc, strontium, selenium, metasilicate and so on. Beneficial minerals, pure water quality, basically reach the standard of silicon-based natural drinking mineral water. The quality of Changping apples grown with mineral water is naturally different.

Changping Apple, a national geographical indication protection product. Changping Apple 1 special product in Changping District, Beijing. Changping apple has high sugar content, fast coloring and nutrient-rich. Changping is rich in apples. The earliest history is recorded in the Ming Dynasty's "Fragography". "Apple, out of the North, Yanzhao is especially good." The Taihang Mountains and Yanshan Mountains meet in the north of Changping, forming a "mountain warm belt" stretching for hundreds of miles. The Wenyu River originates from its yang, and the Bai River traverses its yin, moistening the rich land at the foot of the mountain. This "warm belt" starts from Shangyuan in the east and south to the south. It faces the south and the north, and faces the east and the west. It is neatly cut like a knife. It is magically dotted by nature, giving the apple a comfortable and superior “fengshui treasure”. Changping is one of the earliest regions in the country to introduce red Fuji apples. In April 1980, Changping officially introduced the original Red Fuji strain from Japan, planted in the Xishankou Orchard, and then transplanted it to the Daxinfeng Orchard in Cui Village. Subsequently, the fruit trees science and technology personnel of Changping District carried out a large number of experiments, observations and cultivation work on the introduced Red Fuji apples, and successfully selected the Fuji excellent varieties cultivated in Beijing. Changping has accumulated rich experience and heritage of cultivated Red Fuji apples. Natural conditions Changping has superior light and temperature resources. The average annual light reaches 2764.7 hours. Ample light is not only conducive to the coloration of the skin, but also catalyzes the chemical conversion of starch into sugar and vitamins. At the southern end of the warm zone, the Jingmi diversion channel flows slowly from east to west, separating the mountains and plains organically, such as the same natural “air conditioning” to regulate the regional microclimate. The annual average temperature is 12.1 °C, and the annual temperature index is 106. The average temperature during fruit development is 23.9 °C, and the frost-free period is more than 200 days, which makes the apples have sufficient growth time. The apple ripening period at the end of September and the beginning of October, the temperature difference between day and night reaches 9 -12 ° C, apple sugar content is high, coloring fast; annual average precipitation of 542.9mm, not only meets the needs of apple growth, but also avoids the fruit tree disease caused by excessive rainfall. In addition, according to the Beijing Academy of Agricultural Sciences, the organic matter content of the orchard soil reached 2.08%, and the effective phosphorus, potassium, iron, zinc and boron contents were 2-12 times higher than that of ordinary soil. These trace elements are transformed into apples to absorb trace elements and nutrients that are beneficial to the body, making Changping Fuji apples delicious and nutritious. Changping apple is sweet, but it is not too sweet. From the appearance, Changping apple is more red than the apple peel, the flesh is milky yellow, crisp, meat and refreshing. In recent years, Changping District has also promoted the planting of more than 6,000 acres of “short” apple trees, which are not more than 3 meters high. Not only are the results more, but the fruits are also sweeter, larger and more red, especially suitable for sightseeing and picking. Starting from mid-October, 34,000 mu of apples in Changping District entered the harvesting period, and large and small picking gardens opened the door to welcome tourists. Apple is Changping's "Ace" fruit. Every ripening season, Apple has not yet planted a tree, and most of it has already been ordered. Some apples even price according to the head, the best fruit can be sold for 50 yuan! Changping Apple's delicious and nutritious secret Changping has superior light and temperature resources.
