What do you mean by April breeze?

Describe the weather in April, which is warm and soft.

The middle and late April is the time when the ears of wheat are getting fuller. At this time, the ears of wheat are heavy. If there is wind at this time, it is very bad for wheat, because if there is wind at this time, especially if it is strong, wheat will easily lodging. Everyone may have a deep impression of wheat lodging. Wheat lodging will not be full, and it will increase the difficulty of harvesting. Last year, my family's wheat fell, and the yield of one mu of wheat was not 200 Jin, but the harvest fee was 100 yuan per mu. At this time, there is nothing I can do. I know I will lose money, and I will gain. Otherwise, there will be no way to sow corn. In addition, by the end of April, wheat is about to mature. The wind at this time also refers to dry-hot wind, which is a disastrous weather and is very unfavorable to the high yield of wheat. Popularize the knowledge of dry-hot wind, which is also called fire wind, hot wind or dry wind. When dry hot wind occurs, the temperature can be as high as 30℃ or above, the air humidity is lower than 30%, and the wind speed can reach more than 2 meters per second. After the dry hot wind blows, the wheat plants transpiration. The photosynthesis of leaves can not be carried out well, which often leads to insufficient filling of wheat, and even makes plants wither and die. It can be said that as soon as the dry-hot wind appears, the wheat yield will be seriously reduced.
