Proverbs about late spring and cold weather
There is nothing worse than cold spring, as the proverb goes. It means that the cold weather in late spring can easily lead to diseases.
Late spring cold: a weather phenomenon in which the temperature is warm in early spring and low in late spring. There is nothing worse than a late spring cold when it is dark and cold. It means that the cold weather in late spring can easily lead to diseases.
The late spring cold is mainly caused by long-term rainy weather or frequent intrusion of cold air, or strong radiation cooling on clear nights often controlled by cold anticyclones.
If the average temperature in the last ten days of spring is more than 2℃ lower than normal, it is considered to be a serious late-spring cold weather, which can cause harm to agricultural production, especially if the early temperature is higher than normal and the later temperature is lower than normal. The harm of late spring cold is more serious. It often causes rotten seedlings of early rice in southern my country, as well as rotten seeds or dead seedlings of peanuts, vegetables, cotton and wheat in northern China.
To prevent late spring cold, in addition to improving the level of cultivation and management and keeping warm seedlings and other measures, we must also determine a reasonable sowing period based on the occurrence patterns of late spring cold in various places to avoid its harm.
To put it simply, it means: in the spring, when the weather warms up, the temperature drops significantly due to the intrusion of cold air, thus causing harm to crops. This kind of weather is "warm in the first spring and cold in the second". It is called late spring cold.
