Autumnal equinoxIf you don't see it, food is as expensive as gold, and this proverb is exactly what it isAutumnal equinoxAn old saying related to solar terms. It means ifAutumnal equinoxof the seasonWeatherStill hot, unable to feel the coolness of autumn and the drop in temperature, then it is likely to be a sign of the futureWeatherAbnormalities, such as floods, droughts, etcPour the spring coldand so onWeatherphenomenon, theseWeatherIt will seriously affect the growth of crops. If the production of food decreases, then the ** of the grain will decrease, **naturally**, so the grain is described as "expensive as gold".
Autumnal equinoxIt's our countryWeatherTurning cool turning point of this periodWeatherThe characteristics are mainly reflected in the following aspects:
1.Temperature drop: InAutumnal equinoxAfter that, the average daily temperature gradually dropped below 22 and we entered autumn. Cool breeze, crisp autumn, yesAutumnal equinoxOne of the great features of the season.
2.The temperature difference between day and night increases: withAutumnal equinoxAfter the direct sunlight moves southward, the daylight hours gradually shorten and the night hours gradually lengthen. Therefore,Autumnal equinoxAfter the diurnal temperature difference gradually increases, the crops pass through during the dayPhotosynthesisThe organic matter manufactured can be stored better, which promotes the ripening of the crop.
3.Crops ripen quickly:Autumnal equinoxDuring the season, crops ripen faster due to the increase in the temperature difference between day and night and the cooler temperatures. SoybeansCorn, pears and many other crops will enter the best picking or harvesting period one after another.
So why sayAutumnal equinoxWhat about the points?

If food production decreases, it will, which in turn leads to the high price of food, so it is described as "food is as expensive as gold".
This proverb reflectsFarmersYesWeatherSensitivity to change and emphasis on food production. FarmersWe are very dependent on stabilityWeatherconditions to ensure the growth of crops and a good harvest of grain, therefore,WeatherThe anomaly was a disaster for them.

In modern society, withAgricultureWith advances in science and technology and improved crop cultivation techniques, our crop yields in general are no longer as affected by extreme climate changes as they were in the past. The proverbs mentioned above are more based onFarmersLabor experience as the basis, and inModern agricultureScientific planting, irrigation technology, and weather forecasting can effectively cope with the impact of climate change, thereby stabilizing crop yields.
However, climate change remains a global problem, extremeWeatherEvents such as droughts, floods, heavy rains, etc., are frequent, and have been givenAgricultureProduction presents a huge challenge. Therefore,FarmerswithAgricultureExperts still need to pay close attention to climate change trends and take appropriate measures to adapt to and mitigate climate change impactsAgricultureimpact.
In general, although there is some truth in the old saying, and it contains the wisdom of the Chinese nationFarmersexperience, but in modern society,AgricultureTechnological advances and scientific crop management have been able to effectively and effectively cope with the effects of climate change.
