This year (2022) frost falls on October 23rd of the Gregorian calendar and the 28th of the September 20th of the lunar calendar. The specific time is 18:35:31 seconds. There are also many proverbs about frost and frost reduction among the folk. The meanings contained in some proverbs are still of reference significance until now.
For example, the proverb "Frost falls and frost will rot next year Chencang " is analyzed from the literal meaning. If frost falls on the day of frost fall (some are also said to be during frost fall), then when the next year comes, the crops will rot in the warehouse (two meanings).
Some friends may have questions, is it good or not to fall into frost? What is the statement? The author will talk about this in detail about the content of this article, and you will have the answer after reading it.
From the perspective of agricultural planting, in the proverb "Frost falls and frost will be blown away in the warehouse next year", crops rot in the granary, which has two meanings.
One of them refers to the excessive moisture content in the grain and cannot be dried well, which leads to mold and rotting of the grain. The condition for the formation of frost is that when the temperature drops below zero degrees Celsius, the white crystalline frost of water vapor in the air near the ground, and the frost under the ground indicates that the temperature drops significantly and the temperature is relatively low.
The time for frost falls is in late October every year. In some areas of the Yangtze River basin, as well as some areas in the south, late rice has entered the late stage of growth and has not yet been harvested. Many areas have entered the harvest period after frost falls. If frost is applied on the day of the frost, it means that the local temperature is low, which is not conducive to the later growth of late rice.
At the same time, after frosting, the humidity in the air increases relatively. After the late rice is mature and harvested, the moisture content in the rice grains is relatively large. If it is not dried in time or the drying is insufficient, it will be stored in the granary, which will increase the chance of mold and rot. This is the first explanation of "Frost falls and frost will be damaged next year". From this point of view, frost falls on the day is bad weather.
The second refers to the excessive production of grain, stored in a granary, and even moldy and rotten, it cannot be eaten. implies that frost is applied on the day of frost, which is conducive to the growth of crops and promotes the increase in yield.
From the perspective of wheat cultivation, the Cold Dew period is the peak period for wheat cultivation. After entering frost, most wheat cultivation areas have been sown and some areas have emerged. If you encounter frost after entering the fall, the temperature is relatively low. However, during noon, the temperature is relatively high, and the daily average temperature is still around 10 degrees, which has little impact on wheat seedling emergence.
The frost on the surface, on the one hand, is sublimated into water vapor, and on the other hand, melts into water. It is these water that provides convenient conditions for wheat to germinate and emerge in seedlings. Especially for wheat sowing, there is no irrigation after sowing. The water melted in frost will alleviate soil drought to a certain extent, increase the wheat seedling rate, and lay the foundation for the high yield of wheat in the coming year.
This is the second explanation of "Frost falls and frost will be damaged next year". From this point of view, frost falls on the day is a good weather.
From the above two explanations, it can be seen that frost is good and bad when it comes to frost. The reason is that this proverb is explained from different angles. Different regions and crops will also be different. Rice is planted in the southern region and wheat is planted in the northern region. One is about to mature and harvest, and the other is about to emerge after sowing. From a growth perspective, different weather is required.
So, there are also results that are good and good (the difference between the north and the south). In fact, both are correct, and it depends on which angle it is. With the development of technology, from the precise conditions today, frost falls under normal natural phenomena. As for the subsequent weather, it depends on the local specific weather forecast.
