Xinjiang is located in the inland region of Northwest China. It is far away from the ocean and surrounded by mountains. The wet air on the ocean is difficult to reach, so the rainfall is very small and the climate is dry. The temperature changes a lot day and night, especially in the summer when the sun shines during the day. The temperature is very high and drops sharply from night to night, people use "early wear leather jacket Wu yarn" to describe the temperature difference between day and night.
It is this seemingly harsh climate that produces high-quality fruits.
Because there are few rainy days and many sunny days, the sunshine here is very long. plants can fully perform photosynthesis to produce a large amount of starch, sugar and other substances. At night, the temperature drops very low, and the respiration of plants decreases, which reduces the nutrient consumption. Therefore, the fruit can accumulate a large amount of nutrients, not only grow large, but also have sufficient nutrients. The big and sweet secret of fruits produced in Xinjiang is here.
