1. The difference between winter wheat and spring wheat

Planting area: the planting area of spring wheat and winter wheat is bounded by the Great Wall. Spring wheat is planted in the colder place to the north of the Great Wall, and winter wheat is planted in the warmer area to the north of the Great Wall

Planting and harvesting time: spring wheat is planted north of the Great Wall. It is usually sown from March to April after the Spring Festival, and then harvested from August to September of that year. Winter wheat in the area south of the Great Wall is usually sown between September and October of the flour year, and then harvested between April and may of the following year

Its own characteristics: spring wheat is relatively drought resistant, with short plant type, large ears and short growth period, but its quality is worse than that of winter wheat, which is not as delicious as winter wheat. Winter wheat has strong cold resistance, so it can be sown in October, and its seedlings can survive the winter. When spring comes, its seedlings can soon tiller and squat and grow up. The quality of winter wheat is very good, and the flour is very delicious

Planting climate: spring wheat is planted in cold places in winter. Because the temperature in winter is too low to sow, it can only be sown after spring. Winter wheat is sown in warmer places. It is cold resistant and can carry through winter. It is sown in winter and harvested in summer

2. Origin of winter wheat and spring wheat

China's wheat is mainly planted in the north. The winter in the northeast is very cold, so it can only be sown after the temperature starts to rise in spring. The wheat sown at this time is called spring wheat. The growth cycle of spring wheat is relatively short and the harvest time is relatively early. The winter temperature in North China is slightly higher, so wheat can survive the winter safely, so this area can be sown in winter. Therefore, spring wheat is sown in spring and winter wheat is sown in winter
