In which solar term was the sowing of wheat carried out?

We belong to the Huang-Huai River Basin. Wheat is planted from the cold dew to the first frost every year, that is, from 10 to 25 every year. There are also some growers who plant wheat late because of the wrong stubble. As one of the main food crops in Anhui Province, the planting area in Anhui Province in recent years is basically over 36 million mu, which can be described as a large planting area and a wide region. Basically, rice-wheat rotation is mainly along the Yangtze River in southern Anhui and south of Huaihe River. As the saying goes, the Millennium is early and cold, and the autumn equinox is the time to plant wheat. This refers to the sowing time of winter wheat. Due to the influence of the current climate warming, the sowing date was postponed until after the autumnal equinox and before the cold dew.

There is a proverb called "Look at the early wheat on both sides of the cold dew", which can be about 10 days later than the solar term of the cold dew. Some weather is sometimes warm in winter and solar terms in beginning of winter, so it is not suitable for planting. If you really want to plant, I suggest a variety of wheat. Not too early. If the temperature is too high and too early, the sowing date of wheat will be different in different regions. It is normal for the north and the south to differ by half a month. In some special areas, this difference can be one month. However, the best time for sowing wheat is in June 5438+ 10 every year.

The increase of the second temperature leads to the obvious increase of the accumulated temperature before winter. The accumulated temperature before winter affects the growth and development of wheat before winter. If the seeds are sown too early, the wheat will thrive before winter comes. It is very unfavorable to the cold resistance during the wintering period. As the saying goes, there is no prosperity of wheat. As for the sowing time of wheat, it will vary from region to region. It is normal for the north and the south to differ by half a month. In some special areas, this difference can be one month. So from the time analysis alone, it is probably in the following time period.

At present, China's wheat planting areas include northeast spring wheat area, north spring wheat area, northwest spring wheat area, north winter wheat area, Huanghuai winter wheat area, middle and lower reaches of the Yangtze River, southwest winter wheat area and so on. . . .
