Cold dew wheat or first frost wheat?

On the issue of wheat sowing time, there is a folk saying that "the autumnal equinox is early, the first frost is late, and the cold dew is planting wheat at that time", which means that the sowing in the autumnal equinox is still a little early, and the sowing in the first frost is a little late. The period of cold dew and solar terms is the best time to sow wheat. Judging from the actual situation of sowing wheat in many places, this agricultural proverb is applicable to most major wheat producing areas.

For example, the Huang-Huai-Hai region is the main producing area of winter wheat. Except for the northern and southern regions, most of them are planted in the cold dew solar terms. Sowing wheat in the cold dew solar terms does not mean that it must be sowed on the day when the cold dew comes. This is unrealistic, as long as it is sowed in the cold dew solar terms. The cold dew solar term is from June 7, 2008 to June 9, 2008. This year's cold dew solar term is from June 8, 2008 to June 23, 2008, which belongs to the cold dew solar term.

Sowing time

In the eastern part of Henan province, where the little helper is located, the peak sowing time of wheat here is 65438+ 10/0-15. However, this year has encountered special circumstances. After entering 10, it has been raining. At present, the soil moisture in the field is relatively high, which is not suitable for sowing, and machinery can't work in the field. It is estimated that the peak sowing time this year will be 10+05-20.

In some areas or farmers, wheat will be sown in the autumn equinox and solar terms. The autumnal equinox starts from September 22nd to 24th and ends on or before June 7th and 8th. 10. For the relatively northern planting areas, wheat can be sown after 10, especially after10 May. The local cooling time is earlier, and the sowing date of wheat can be advanced appropriately without affecting the normal growth.
