The fourth national cold wave is coming! What impact will it have on industrial and agricultural production?

Cold wave weather refers to the sudden drop of temperature, accompanied by strong winds, rain and snow. This will have a serious impact on our industrial and agricultural production.

First, low temperature freezing injury.

Cold wave weather has a serious impact on agriculture. Winter wheat is mainly planted in China, and the freezing injury of winter wheat is caused by many factors. But the most important factor is low temperature freezing injury. Generally speaking, winter wheat can withstand a certain degree of low temperature, but below 0℃ it will cause damage to winter wheat. If the temperature is below-10℃, the wheat seedlings will wither to some extent, even lead to the death of the wheat seedlings.

Second, there is not enough light.

Cold wave weather is often accompanied by weak light. At this time, crops will have the following conditions: slow metabolism, slow growth of various tissues and organs of crops, and sometimes crops will not die directly, but they may not wither but will not grow. This situation is generally called. Dead seedlings? .

For fruits and vegetables, the influence of cold wave weather is also very great. Under the condition of low temperature and insufficient light, the fruits of fruits and vegetables will bloom and their fertilization will be affected. That is to say, although there is no effect in a short time, when it really blooms and bears fruit, there may be fruit deformity, hollow fruit and so on. The disaster caused by this cold wave weather is also irreparable.

Third, the impact on land.

Cold weather will lead to weak growth of agricultural products. In severe cases, many crops may get sick and be infected with some fungal viruses, such as Sclerotinia sclerotiorum and root rot. Under the infection of these fungal viruses, it often affects not only the harvest of the year, but also the subsequent land planting.

So the cold wave weather is very harmful to the development of industrial and agricultural production. We can give early warning and take corresponding defensive measures to reduce losses within our ability. Implement precise anti-freezing measures to allow farmers to resume production as soon as possible.
