What vegetables are suitable for rainy and solar terms in North China?
In terms of physical geography, North China generally refers to the vast area north of the Qinling-Huaihe line and south of the Great Wall in China, and borders northeast China and Inner Mongolia Autonomous Region in the north. It is roughly bounded by the isoline of accumulated temperature ≥ 10℃ (3000℃ in the northwest section) and the isoline of 65438+ monthly average temperature-10℃ (-8℃ in the northwest section).
The political, economic and geographical scope of North China includes five provincial administrative units: Beijing, Tianjin, Hebei, Shanxi and Inner Mongolia Autonomous Region. The soil in North China belongs to alluvial yellow soil dryland type, which is the main wheat producing area in China. Its Beijing-Tianjin-Hebei region is the largest and most dynamic region in northern China.
During the period of Three Emperors and Five Emperors, North China belonged to Jizhou, one of the ancient Kyushu. During the Yao and Shun period, China was divided into twelve states due to floods, while the north and south of Yu Shun were too far away from Jizhou, so it was separated from Youzhou in the northeast and merged into due north. After the flood control, Yu was reunited with Kyushu and belonged to Jizhou.
