Is it late to plant wheat in the first frost?

The first frost planted wheat late, north of the middle and lower reaches of the Yangtze River. It is not too late to plant wheat in the first frost, south of the middle and lower reaches of the Yangtze River.

The area north of the middle and lower reaches of the Yangtze River should start sowing before the first frost, and the area south of the middle and lower reaches of the Yangtze River can sow after the first frost or postpone sowing until the winter festival. Generally speaking, the germination temperature of winter wheat is around 15℃, and the germination is very slow below 15℃, and the wheat does not germinate below 10℃. Low temperature in autumn and winter will affect the sowing, germination, emergence, tillering and seedling raising of wheat. It is suggested that wheat planting in the north of the middle and lower reaches of the Yangtze River should start from the Cold Dew Festival and not be postponed until the first first frost Festival. The area south of the middle and lower reaches of the Yangtze River should be planted before or after the first first frost Festival, and it cannot be postponed until the beginning of the winter festival.
