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℃, so that the water in the cells will continue to penetrate outward, resulting in dehydration of the cells, resulting in partial withering or complete death of the plants.

2. In the early stage of the cold wave, the temperature will drop sharply, and the immune ability of animals will drop sharply, causing epidemic diseases.

3. The temperature drops, the road is blocked by heavy snow, and it is difficult for animals to find food; Causing animals to continue to die in large numbers.

4. It is cold and dry in winter, which is not good for crop growth.

The favorable influence of cold wave on agricultural production;

1, snowfall has a certain protective effect on overwintering crops, and the melting of snow in the coming year will become a valuable water resource to alleviate the spring drought.

2. Cold wave and low temperature can freeze to death some pests and diseases, reduce the pests and diseases of crops in the coming year and reduce infectious diseases of livestock.

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 coming from polar regions or cold zones in winter half a year, which invades the middle and low latitudes on a large scale like tides.

When a cold wave strikes, the temperature will drop sharply, accompanied by strong winds, rain and snow. It has a serious impact on industrial and agricultural production, people's lives and human health.
