cold dew solar terms bring harm to

1. Affect production. During the perennial cold dew period, the rainfall in South China is also decreasing. Most of the western part of South China is about 20mm, and the eastern part is about 30 to 40mm. Continuous rain is very frequent, day and night, and Ming Ming is falling, which affects the "three autumn" production and has become a disastrous weather in most parts of southern China.

2. Affect sowing. The climatic characteristics accompanied by continuous rain are: high humidity, more clouds, less sunshine, more cloudy days, and fog days have increased significantly since then. However, whether autumn rain is serious or not directly affects the progress and quality of "three autumn". Therefore, on the one hand, we should use weather forecast to harvest and sow in sunny days; on the other hand, we should also take various effective farming measures such as deep ditch and high compartment according to local conditions to reduce wet damage and improve sowing quality.

Farmers should pay attention to preventing the freezing injury in the field.

2. When fishing in autumn, the sun is not as fierce as in summer, and it is difficult to get through in the deep water, so fish and crabs move to warmer shallow water, which is a good time for fishing near the water.
