Why should wheat be put in the second place?

Wheat is a temperate plant with long sunshine and wide adaptability, ranging from north latitude 17 ~ 50, from plain to plateau at an altitude of about 4000m (such as Tibet and Xinjiang Plateau in China).

Influenced by objective factors such as climate and geographical conditions, the internationally and domestically recognized high-quality wheat producing area is about 36 N, and the domestic Shandong Gaomi wheat is recognized as the "golden wheat area" with high quality, and it is known as "Northeast rice, high-density wheat (flour)" among the people.

Wheat is a gramineous plant, which is widely planted all over the world. It originated from the fertile crescent zone in the Middle East and is one of the earliest cultivated crops in the world. The caryopsis of wheat is one of the staple foods of human beings, which can be made into bread, steamed bread, biscuits, noodles and other foods after being ground into flour. After fermentation, it can be made into beer, alcohol, vodka, or biomass fuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, nicotinic acid, vitamin A and vitamin C, etc.

Wheat is one of the three major cereals. Almost all of its output [1] is edible, and only about one sixth of it is used as feed. In 20 10 year, wheat was the second largest grain crop in the world (65 100 tons), second only to corn (844 million tons).
