What should be planted in the north from the Millennium to the autumnal equinox?

Winter wheat should be planted in the north from the Millennium to the autumnal equinox. The 24 solar terms can guide agricultural production. For example, planting winter wheat in Shandong and Henan means "early dew and late cold dew, and planting wheat in autumn equinox is just the time".

Winter wheat is planted in a slightly warmer place. Generally, it is sown 10 from the middle and late September to the early June, and ripens from the end of May to the middle and late June of the following year. For example, North China and its south are all winter wheat. In China, it is generally bounded by the Great Wall, with spring wheat in the north and winter wheat in the south. China is dominated by winter wheat.
