Apple with rock candy heart is a kind of apple produced in Aksu. Because the sugar in its core is piled up into a transparent shape, it forms a unique "rock candy heart" in the world, so it is called "rock candy heart" apple.

The temperature difference between day and night in the high altitude area of Aksu is large, the sunlight is sufficient, and the soil is fertile, which makes the apples have high sugar content, and the sugar content is around 18 degrees, which makes them taste particularly sweet. Aksu apples are watered by glacier snow water and cultivated in sandy soil, and they produce "sugar-hearted" red Fuji apples.

Origin of apple with rock candy heart

Aksu means "clear water" in Uyghur language, and is known as the "south of the Great Wall". The rainfall here is scarce and the climate is dry, but it is densely covered with water systems and rich in water flow, nourishing a fat oasis; Rich in light and heat resources, the annual average total solar radiation is 130-14/kcal, the sunshine is 2855-2967 hours, the frost-free period is 205-2 19 days, the average annual temperature is 7℃-8℃, and the winter is cold.

There are few diseases and insect pests in the fruit growing period, and the high altitude, large temperature difference between day and night, sufficient sunshine, and the use of pollution-free glacier and snow-melting river-Kekeya River irrigation, sandy soil cultivation and other characteristics make the sugar in the core of apple pile up into a transparent shape, forming a unique "rock candy apple" in the world.

The last process to control the quality of rock candy heart is the frost period in Aksu area1early October, so the production of "rock candy heart" apples in Aksu is extremely regional, and the annual output of pure fruit is only 5,000 tons.
