The Yantai hills account for 39.7% of the city's total area. The temperature difference between the ravine and the hills is large, suitable for the accumulation and full coloring of the cherry sugar. The warm temperate continental monsoon climate is extremely consistent with its growth cycle, and the country's unique North Sea climate is dry and not wet in summer. Winter is not dry, fruit trees are not suitable for mold and other diseases; sandy soil with deep soil, loose soil, good air permeability and strong water retention is most conducive to cherry growth.

China has cultivated cherries for more than 3,000 years, and it has been more than 100 years since the introduction of large cherries. There are about 120 species of cherries in the world. There are three kinds of cherries in our life: Chinese cherries, Chinese cherries and imported cherries. Chinese cherries are also called "peach", commonly known as small cherries, native to China. In the Zhou Dynasty's "Book of Rites and Moons", it is recorded that "the shame is the first to recommend the temple." The "peach-containing peach" here is the cherry. It can be seen that the cherry has been used as the precious fruit of the ancestors. The fruit is small, the flesh is soft and the skin is thin, and it is not resistant to storage and transportation, so it is basically digested locally. Chinese cherries and imported cherries are European cherries. European cherries include sweet cherries and sour cherries, originating from Asia Minor between the Black Sea and the Caspian Sea. The Greeks took the lead in planting cherries and were later promoted by the Romans. Around 1630, the British brought the cherries to the North American continent. Later, the Spanish missionaries who arrived in the United States made the cherry planting industry flourish, making the United States the cherry kingdom of the time. European cherries are constantly evolving, introducing, nurturing and becoming the imported cherries we eat now. As European cherries flourished in the United States, in 1871. American missionary J. L. Nevius introduced the first batch of 10 sweet cherry, sour cherry and hybrid cherry seedlings, and opened a demonstration farm of more than 10 acres on the southeast slope of Yantai dome, called "Guangxing Orchard". Nivis was cultivated by means of grafting and nursery, and the results were extremely successful. He provides fruit seedlings to farmers free of charge every year and introduces cultivation techniques. The Yantai Big Cherry has been promoted since then and has a history of 147 years. The Yantai hills account for 39.7% of the city's total area. The temperature difference between the ravine and the hills is large, suitable for the accumulation and full coloring of the cherry sugar. The warm temperate continental monsoon climate is extremely consistent with its growth cycle, and the country's unique North Sea climate is dry and not wet in summer. Winter is not dry, fruit trees are not suitable for mold and other diseases; sandy soil with deep soil, loose soil, good air permeability and strong water retention is most conducive to cherry growth.
