The Beginning of Autumn will not accept both ends in June. Will the Beginning of Autumn really reduce production in the autumn harvest in June this year?

Recently, everyone is very concerned about the problem of the Beginning of Autumn, but now we can see that Greater Heat has not yet arrived, and it is still some time before the Beginning of Autumn. This year's the Beginning of Autumn is on the 26 of June of the lunar calendar, that is, August 7 of the Gregorian calendar. It just corresponds to the first half of the saying, "the Beginning of Autumn in June, don't take it at both ends."

What exactly does this sentence mean?

First, let's take a look at the Beginning of Autumn. The Beginning of Autumn is the first solar term in autumn, but although the Beginning of Autumn is the first solar term in autumn, the weather is not cool at this time, because there are still more than ten days between the Beginning of Autumn and the End of Heat, and the weather is still very hot.

Why is it bad for the Beginning of Autumn in June?

Because of the calculation of the astronomical calendar, the Beginning of Autumn's time varies from year to year. This year's the Beginning of Autumn is in June, but some years are in July. It is obvious that if the Beginning of Autumn stands in June, the weather will turn cooler earlier, and the cooling of crops during the growing period will naturally affect the grain harvest.

But why do you say "do not accept both ends"?

If you only talk about the autumn harvest, it is easier to understand, because during the autumn harvest season, if the weather turns cold earlier, it will naturally affect the growth of the autumn harvest crops. But why does it still affect the "summer harvest"?

Since the Beginning of Autumn is in June, the natural solar terms in front of the Beginning of Autumn are also higher than those in other years, which will naturally affect the summer harvest. For example, Qingming Festival, Qingming Festival this year is on the 20th of February in the lunar calendar. Naturally, the weather at this time is still very cold, which is very disadvantageous to the growth of wheat. Coincidentally, wheat in North China has been affected by the cold in late spring this year. This year's poor summer harvest has become a reality. However, the state of the autumn harvest depends on the next two months.

However, you may overlook one small problem, that is, the area produced by the 24 solar terms, which has a lot to do with the application of 24 solar terms. 24 solar terms existed as early as the Qin and Han dynasties. The resulting area is near the Yellow River basin. Therefore, most of the 24 solar terms related to agriculture are applicable to the agricultural activities of the Yellow River.

Here, let's take a small example. Take the Beginning of Autumn as an example. Although the Beginning of Autumn is a member, many parts of our country are not entering autumn in the real sense. Because the measure of whether to enter the autumn depends on the continuous accumulated temperature of a place. If there is a situation where the average temperature is below 22 degrees for more than five days, this place will really enter autumn. But the Beginning of Autumn, like the northeast region, has already entered the autumn mode, while the Huai-Hai region will be some time after the Beginning of Autumn.

Therefore, from this point of view, agricultural activities can not be determined entirely on the basis of rural sayings, and agricultural activities must be adopted in accordance with local conditions.

The above comes from promoting agriculture through science.
