Introduction: "I am most afraid that the fourth day of November is a sunny day", today is the fourth day of November, what is so terrible about a sunny day?
In recent days, everyone has been talking about the cold wave weather, and the temperature drop in both the south and the north is very large, and there is even a drop of 20 degrees in some places, which is really not small! Everyone pay attention to keep warm, don't catch a cold.
Judging from the forecast, on the morning of December 15, there was even extremely cold weather below -40 °C in the northeast of Inner Mongolia and northern Heilongjiang in the mainland, of which the lowest temperature in Tuli River in Inner Mongolia was only -44.3 °C, which was very cold!
In addition, in the next two days, the minimum temperature in some parts of North China, Huanghuai and other places in the mainland will also be close to or break the record, encountering rare cold in the same period.
After all, it is normal for us to cool down and snowfall during the cold wave, but after all, the time is short, and a few days may have passed, which may not have such a big impact on the overall warmth of this winter.
In fact, it is a warm winter or a cold winter, and the impact on us is not so great. However, for the ancient laborers, the influence was greater, and they preferred the colder winters.
Because the cold winter can freeze the bacteria and pests in the soil, preventing them from overwintering, so that the crops will be less pests and diseases in the next year. After all, there were no pesticides in ancient times, and if you get pests and diseases, it will cause a large-scale reduction in production, or even extinction.
In addition, the cold winter means that there will be less "inverted spring cold" in the spring, which is beneficial for the growth of crops and the planting of crops in early spring.
Today is the fourth day of the eleventh month of the lunar calendar, and there is a saying among the people that "the fourth day of the eleventh month is the most afraid of a sunny day". What does that mean? What's so scary about this sunny day? Let's take a look at what the agricultural proverb says!
In January, the fourth day of November is warm, and the ducks will freeze to death in the spring of the next year
This agricultural proverb is an exaggerated statement, to the effect that if the weather on the fourth day of the 11th lunar month is very warm, then it indicates that there may be extremely cold weather in the spring of the next year, and may even cause ducks and other waterfowl to freeze to death, indicating that "spring cold" has come.
The sudden drop in temperature may cause crops to suffer from low temperature and frost damage, affecting their normal growth and development; may lead to low soil temperature, affect the germination and growth of seeds, and lead to the phenomenon of rotten seeds; it may also lead to the decline of crops' disease resistance, which is easy to cause various pests and diseases, affecting the yield and quality of crops; and may also lead to the obstruction of crop growth, delay the maturity period, and affect the harvest and market time of crops.
2. On the 4th day of November, the harvest was reduced by drought in winter and cold in spring
This agricultural proverb has a similar meaning to the effect that if the weather is clear on the fourth day of November, it will indicate that the winter will be mainly sunny and dry, which will lead to drought in the winter and cold weather in the spring, which will have a negative impact on the growth and harvest of crops.
The winter is cold and snowy, which is very beneficial to overwintering wheat and other crops, mainly reflected in the following aspects:
1. There is a lot of snow in winter, which can play a role in anti-freezing. Winter weather is cold, and wheat seedlings cannot withstand the severe cold. Through snowfall or watering, the ground temperature can be increased and the occurrence of wheat frost damage can be reduced.
2. There is a lot of snow in winter, which can alleviate the drought in spring, which is conducive to the growth of crops and the sowing of spring crops.
3. There is more snow in winter, more nitrogen, and when the wheat returns to green next year, the moisture in the field is maintained better, which is conducive to returning to green, and the root system is firmly rooted to promote the middle and late stage of strong seedlings.
4. There is a lot of snow in winter, which can reduce the temperature variation, narrow the temperature difference, and prevent freezing and death of seedlings caused by violent temperature fluctuations.
Therefore, there is a saying that "the fourth day of November is the most afraid of a sunny day." "Because a sunny day means that the winter is dry and has little rain and snow, it is a warm winter, which is not conducive to the growth of crops.
Today, the fourth day of November, it's a sunny day on our side, and I'm looking forward to sharing it! Thank you for reading.
