What are the adverse and beneficial effects of cold wave on agricultural production?

Adverse effects of cold wave on agricultural production:

1. When the cold wave brings frost, the temperature will drop below 0℃, causing the water in the cells to continuously penetrate outward, causing the cells to Dehydration causes partial wilting or complete death of the plant.

2. The cold wave will cause the temperature to drop sharply early, and the immunity of animals will drop sharply, causing the epidemic of epidemic diseases.

3. Due to the drop in temperature and road closures due to heavy snow, it has become difficult for animals to find food, leading to the continuous death of large numbers of animals.

4. Winter is cold and dry, which is detrimental to the growth of crops.

The beneficial effects of the cold wave on agricultural production:

1. Snowfall has a certain protective effect on overwintering crops. The melting of snow in the coming year will become valuable water resources to alleviate spring drought.

2. The cold wave and low temperature can freeze some pests and diseases to death, which will reduce crop diseases and pests in the coming year and reduce livestock infectious diseases.

3. The precipitation is large, the water source is sufficient, and the rain and heat are in the same period. Conducive to crop growth.

Cold wave: refers to the cold air from the polar regions or frigid zones in the winter half of the year, which invades mid- and low latitudes on a large scale like a tide.

When a cold wave hits, it will cause a sharp drop in temperature, accompanied by strong winds, rain and snow. It has a serious impact on industrial and agricultural production, people's lives and human health.
