Introduction to Xiangshan Sand Watermelon

Zhongwei Xiangshan Sand Watermelon, also known as "Zhongwei Selenium Sand Watermelon" due to its high content of the healthy element "selenium" in the product. The main production area of Zhongwei selenium sand melon is Xiangshan Township, where watermelons are known as "Gobi watermelons" and "watermelons in the crevices of rocks", and are a specialty of Zhongwei City, Ningxia Hui Autonomous Region. Named after its origin in the Xiangshan area of Zhongwei City and the use of sand compaction cultivation techniques. Combined with the local special precipitation, light, temperature difference, and soil conditions, the watermelons produced are not only large and sweet, but also have thick skin, hard texture, and are resistant to storage and transportation, with a natural shelf life of over 50 days

The so-called sand compaction refers to pressing stones on sandy land, which can reduce water evaporation during the day and condense water vapor into water when it cools at night and infiltrate through the stones. This can not only store water, retain moisture, and keep warm, but also increase the nutrition of crops. It can also avoid water and wind erosion and reduce soil erosion. Through sand compaction, the previously unused dry sandy land has become a treasure trove for growing watermelons. At the same time, due to the special climate experienced by gravel for many years, it is rich in various minerals and trace elements. When the rainwater that washes away the gravel is absorbed by the roots of selenium sand watermelon, it creates the sweet and delicious characteristics of Xiangshan pressed sand watermelon, which is rich in various nutrients

Xiangshan pressed sand watermelon is known as the "sweet melon grown in the crevices of stones". It is a characteristic melon planting model in which farmers in the Xiangshan area of Zhongwei cover a large amount of crushed sand and gravel on the surface of the mountain in the Xiangshan impact fan area with rich sand and gravel accumulation, and use the water-saving, warming, and moisture preservation effects of gravel paving to plant watermelons and sweet melons. The produced watermelons and cantaloupes have large and thick skin, are easy to transport, have bright red flesh, rich juice, sweet and refreshing taste, and are as comfortable as honey. The sugar content is as high as 13.8%. The nutritional content of the produced melons is comprehensive and reasonable, including 18 essential amino acids, 3 vitamins, and 5 trace elements for the human body. Among them, they contain 56 mg/kg of calcium and 1090 mg/kg of potassium, especially trace elements such as selenium and zinc that are essential for human health. They have the effects of improving human immunity, anti-aging, and cancer prevention

1. Sensory characteristics: The fruit is elliptical in shape, with a light green skin color and dark green stripes on top.

The flesh is bright red and crisp; The seeds are black brown in color, the skin is tough, the thickness is 10mm to 15mm, and they are resistant to storage and transportation

2. Physical and chemical characteristics: The average central sugar content is 11.9%, the average edge sugar content is 10.2%, the average gradient difference in sugar content is 1.7%, calcium is ≥ 50mg/kg, potassium is ≥ 1.09g/kg, zinc is ≥ 0.36mg/kg, selenium is ≥ 0.0056mg/kg, vitamin C is ≥ 250mg/kg, aspartic acid is ≥ 3.14g/kg, and total carotene is ≥ 1.72g/kg

Zhongwei City is located in the central part of Ningxia, at the junction of mountains and rivers. The arid zone in the middle is vast, with abundant light and heat resources. The average annual sunshine hours is 2854.9 hours, and the average frost free period is 153 days. The active accumulated temperature of ≥ 10 ℃ is 3178 ℃ (the accumulated temperature required for watermelon from flowering to maturity is 800 ℃ -1000 ℃), and the temperature difference between day and night is 12-16 ℃, especially during the flowering period. The suitable temperature difference between day and night and sufficient light are conducive to the accumulation of dry matter and sugar in melon crops
