Is it raining in the long summer?

Whether it rains in long summer is good or not, different situations will have different effects.

The long summer solar term is at the turn of spring and summer, which is quite special because some crops have reached the critical period of grain filling growth, such as winter wheat planted in the north. If a lot of rainfall is not conducive to the growth of wheat, as the saying goes, "an inch of land is not afraid of water, and a foot of wheat is afraid of water." In other words, irrigation should be increased when the wheat turns green in spring, and once the wheat enters the filling stage, it can't be flooded. Therefore, from the perspective of wheat farmers, it is not good to rain in long summer.

But at the same time, some new crops will be planted around the long summer, such as "there are big potatoes in the long summer, and a tree has a big basket." The long summer solar term is very suitable for planting sweet potatoes, because sweet potatoes are crops that are afraid of cold. Around the long summer, the national average temperature is 18-20℃, and sweet potatoes can already start to grow. If you don't plant it, it may not grow because of low temperature. People hope it will rain because sweet potato is a newly planted crop.
