The main disastrous weather that harms Guangdong's agricultural production in winter is cold wave.

Cold wave is a natural weather phenomenon. As the name implies, cold air rushes in like a flood. It belongs to a form of air (cold air) flow. Cold wave is cold air from high latitudes, which rapidly intensifies and invades middle and low latitudes under certain weather conditions, resulting in a wide range of severe cooling, strong winds and rain and snow weather along the way. When this cold air reaches a certain standard, it is called a cold wave.

Cold wave is cold air from polar regions or cold zones in winter, 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.

Preventive measures of cold wave

Step 2 take measures

Ensure the safety of agricultural production. Counties (cities, districts) and the Municipal Bureau of Agriculture should organize agricultural technicians to go deep into the front line, actively guide and help the masses to take various defensive and remedial measures, and minimize disaster losses. Take facility agriculture as the defense focus, and do a good job in the defense work such as shed reinforcement, shed film compaction, warmth and antifreeze. Strengthen fence reinforcement and livestock immunization, keep young animals warm, improve the cold and disease resistance of livestock and poultry, and ensure safety.
