The key to authentic dried tangerine peel lies in "land". Without this "land", it is not authentic.
The authenticity of Xinhui Chenpi is inextricably linked with Xinhui's native land.
This is related to natural phenology and human wisdom.
Because of the climate, it is warm and humid here-surrounded by the sea on three sides.
Xinhui, as a whole, is in a subtropical monsoon climate, with the characteristics of high temperature and rainy summer and mild and rainy winter.
This climate is naturally very suitable for the growth of citrus, so Xinhui has the reputation of "Dongjia Orange and Jia Xi Citrus".
At the same time, Xinhui belongs to a plain area with slight hills, with Guifeng Mountain (545 meters above sea level) in the north, Dougu Mountain (982 meters above sea level) and Niuguling Mountain (392 meters above sea level) in the south, surrounded by Yinzhou Lake and its plain area, and facing the sea in the south, forming a small geographical pattern of "three mountains holding the ground and three mountains facing the sea", which is unique due to different landforms.
According to the temperature records of Novelty Retrieval Association for 44 years, the daily average maximum temperature in Xinhui is 27℃, while the daily average minimum temperature is 2 1℃.
This is almost completely consistent with the optimum temperature of Xinhui orange growth of 23℃-27℃. Good temperature can make the oil chamber of citrus grow freely and expand as much as possible, while the temperature difference is small, so that the growth of citrus will not be affected by the climate temperature difference, ensuring the continuous fullness and filling of the oil chamber, storing more specific volatile oil and forming rich aromatic quality characteristics.
The oil bubbles in the orange peel produced by it are obviously reduced, such as the orange peel produced in Shaoguan, Guangdong.
The size of the oil bubble is only half of that of Xinhui Tea Branch Citrus, with insufficient fragrance and obvious citrus flavor.
In summer and autumn, the growth of citrus in Xinhui is affected by the marine monsoon season as a whole. The humid air in the South China Sea goes from south to north along Yinzhou Lake, forming a continuous humid rain environment (75% of the normal air humidity), covering the whole territory of Xinhui, where "three mountains are flat and three mountains are close to the sea". The annual precipitation in Xinhui is about 1.5 times that in Yulin, a non-offshore area at the same latitude (the annual precipitation in Xinhui is 2 150).
At this time, citrus is in the period of fruit growth and expansion. The continuous rain ensures the water needed for citrus growth, promotes the transport of nutrients and promotes the growth of citrus, forming the characteristics of large peel and suitable thickness.
