In which areas of our country is cinnamon soil distributed? What is suitable for growing? Cinnamon soil refers to the brown soil, also known as brown forest soil, which is developed in the semi-humid area of warm temperate zone with good drainage, weak leaching and accumulation of carbonate and secondary stickiness. The parent material of soil formation is rich in lime, and the soil formation process is in the decalcification stage, which is a soil with the characteristics of sticking and calcareous leaching and deposition.

Cinnamon soil is widely distributed along the Mediterranean coast of Western Europe, northern Africa, Russia, the southwestern United States, northern Mexico, western South America, and Australia.

In which areas of our country is cinnamon soil distributed? In China, cinnamon soil is mainly distributed between latitude 3440 °N and longitude 103 °122 °E, that is, Guanzhong, southeast Shanxi, western Henan, Yanshan, Taihang Mountain, Luliang Mountain, Qinling Mountain and other mountain hills, alluvial fans and high terraces, the horizontal zone is located in the west of brown soil, and the vertical zone is located under brown soil. From the Piedmont of Yanshan and Taihang Mountains in the north, to the Piedmont low hills of Mount Tai and Yishan in the northwest and southwest, to the southeastern Shanxi and Guanzhong basins in Shaanxi Province in the west, and to the northern foot of Qinling Mountains and the first line of the Yellow River in the south, it is generally distributed below 500m above sea level. the groundwater table is below 3m, with a variety of parent materials and weathered materials of all kinds of rocks, but it is still dominated by loess.

The average annual temperature of cinnamon soil area is 10: 14 ℃, precipitation 500~800mm, evaporation 1500~2000mm, which belongs to the warm temperate semi-humid continental monsoon climate. Its natural vegetation is represented by the dry and bright forest of Liaodong, Robinia pseudoacacia and cypress, and the shrub steppe represented by sour jujube, bauhinia and thatch. The main producing areas of wheat, corn, cotton and apple in northern China generally have three crops in two years or two crops a year.

What is suitable for planting in cinnamon soil? The semi-dry and moist monsoon area of warm temperate zone distributed by cinnamon soil has better light and heat conditions, and most of them have been reclaimed as agricultural land, which is suitable for planting many kinds of dry crops. generally, they can be cropped three times a year or twice a year, with deep soil layer and good tillage, which is the main cultivated soil in the area. Due to the deep main body and moderate soil texture, it is widely suitable for growing grain and cash crops such as wheat (mostly winter wheat), corn, sweet potato, peanut, cotton, tobacco, apple and so on.
