What's the effect of cold spring?

The so-called late spring cold is that when the weather starts to get warmer in spring, a cold current suddenly returns to winter, and the effects of late spring cold are as follows:

First, it is unfavorable to crop production. Especially in the north, wheat will start to grow when the temperature exceeds 15 degrees. If the weather is warm for a period of time and the wheat grows taller and then it is cold again in spring, then the wheat may freeze to death. So farmers sometimes don't want to plant wheat a few days later, because the wheat may grow a little later and harvest a few days later, but they are not afraid of freezing wheat at the end of winter. When the wheat is not picked, it is not afraid of freezing. In addition, wheat is generally grown in the north. In spring, the weather is relatively dry. Years later, everyone is fertilizing and watering to fight drought. Once the drought comes, the cold spring suddenly comes. At this time, the wheat field is wet, which makes it easier to freeze to death. Therefore, the late spring cold is not conducive to the production of wheat and other crops.

Second, it is not good for people's health. Because after spring came, we thought it was warm, and everyone began to put on spring clothes. As a result, I caught a cold in spring At this time, people may wear less clothes and add clothes in time, which may cause some diseases such as colds and colds. Many diseases are caused by abnormal cold and warm weather, so the cold in late spring may cause a large area of cold.

In a word, the cold in late spring is an abnormal weather phenomenon. I suggest that you can always look at the weather forecast and try to avoid the harm that the cold in late spring brings to crops and people.
